TECHNICAL FIELD The present invention relates to a communication, and particularly to the upstream channel power limited circumstances user equipment under power control method, a user equipment and a communication system. Background technique In the long term evolution (LTE, Long Term Evolution) system, the user equipment transmits a physical uplink shared channel (PUSCH, Physical Uplink Share Channel), a physical uplink control channel (PUCCH, Physical Uplink Control Channel) for the uplink sounding reference signal (SRS, Sounding the power control method Reference signal) and a physical random access channel (PRACH, physical random access channel) when defined. When you configure multiple carriers, independent of the power of the uplink transmission signal power control in each cell, wherein: When not simultaneously transmit PUSCH and PUCCH, PUSCH power control formula is: <,. F corpse CMAX, c ( ''), -RrT EARTH (i) = mm 1 ' [l01og10 ( pUSCHjC( ) + ¾_PUSCH, (7) + ac (j) · PLC + ATF，C ('') + fc [DBm] (1); when the PUSCH and PUCCH can transmit power control for PUSCH formula: p 、 = mm. i 11 0 1ο§10 (^CMAX.c (0 - -PpUCCH ( ) , ^ PUSCH c\l) I r ' 10 log10 ( PUSCHjC ('■)) + i¾_PUSCH,c (J) + ac (j) .

When a user is configured to simultaneously transmit PUSCH and PUCCH, the same user device in the same sub-frame in a while or send PUSCH and PUCCH on multiple carriers. But only in the main members of the PUCCH transmission carrier (PCC, Primary Component Carrier) on. PUSCH carried by the uplink control information (UCI, Uplink Control Information) contains all the control information for the corresponding uplink carrier, and the information only within the uplink PUSCH transmission on a carrier. That is all the corresponding uplink carrier control information, either combined or discarded based in part on a predetermined criterion, ultimately only on a CC PUCCH and / or PUSCH transmission. When the transmission power of the uplink signal exceeds a user-configured maximum power output device (PCMAX, Configured Maximum Output Power), it shall become a user of power output overflow, the user device when sending the uplink signal transmission power used by the user equipment will be equal to the maximum output power configuration. The user equipment will be corresponding uplink channel power adjustment. Figure 1 is a schematic view of LTE-A system, a user device in the same sub-frame to send on different cells simultaneously multiple PUCCH; Figure 2 is a LTE-A system, a user device in the same sub-frame in different simultaneously transmitting on a plurality of cell schematic PUSCH; Figure 3 is a LTE-a system, a user device in the same sub-frame to send schematic PUSCH and PUCCH in different cells at the same time; Figure 4 is a LTE-a system user devices in the same sub-frame to send schematic PUSCH and PUCCH at the same time on the main serving cell. Shown in Figure 1, the use of carrier aggregation technology, so when the user device is configured with more than one service area, will appear in the same sub-frame, a plurality of PUCCH sent on different cell service at the same time; or, as shown in Figure 2 , on the different services simultaneously transmit multiple cell PUSCH; or, 3, and sends PUSCH Hekou PUCCH. On the other hand, since the user device capabilities have been enhanced, shown in Figure 4, the user equipment can transmit in the main serving cell while PUCCH and PUSCH (Primary Serving Cell) on the same sub-frame. When this occurs, that is, in the same sub-frame user devices need to send multiple PUSCH, or user equipment needs to simultaneously transmit PUSCH and PUCCH, there will be more than the sum of the PUSCH transmission power is greater than the maximum configuration of a user device output power, or the sum of the PUCCH and PUSCH transmission power is greater than the maximum output power of user equipment. In order to guide the user equipment transmit power allocation in this case, in the standardization of LTE-A power control method defined in the user equipment transmits power limited circumstances. Specifically: When multiple PUSCH only without the need to send the UCI the same time, if at this time to obtain the total transmission power exceeds the maximum output power of user equipment, the user equipment on each PUSCH equal shares to reduce the transmission power until the total guarantee the transmission power is less than or equal to the maximum output power of user equipment. When PUSCH and PUCCH with no need to send the UCI the same time, if at this time to obtain the total transmission power exceeds the maximum output power of user equipment, the user equipment first ensure that meet the PUCCH transmission power, Then PUSCH on each share equally the UCI without reducing transmission power, to ensuring that the total transmission power is less than or equal to the maximum output power of the user equipment, as shown in equation (4 For example, when the PUSCH and PUCCH does not contain UCI simultaneous transmission priority to ensuring the transmission power PUCCH channel Σ W (· 4uSCH, c (0≤ ((0 - 4uCCH () ( 4) When PUSCH PUSCH without UCI and the UCI with the need to send the same time, if at this time to obtain the total transmission power exceeds the maximum output power of user equipment, the user equipment first guarantee to meet with UCI transmission power of the PUSCH, then PUSCH on each share equally the UCI without reducing transmission power, to ensuring that the total transmission power is less than or equal to the maximum output power of the user equipment, as shown in equation (5 For example, when the PUSCH PUSCH containing UCI and UCI do not contain simultaneous transmission priority to ensuring the transmission power of the PUSCH containing UCI, In AuSCH;, C (0≤ (^ CMAX (0 - AuSCH ,; () When PUCCH, PUSCH PUSCH without UCI and the UCI with the need to send the same time, if at this time to obtain the total transmission power exceeds the maximum output power of user equipment, the user equipment first PUCCH transmission power guaranteed to meet, followed by guarantee meet with UCI PUSCH transmission power, and then on each PUSCH without UCI equal share to decrease the transmission power until ensure that the total transmit power is less than or equal to the maximum output power of user equipment, such as formula (6 For example, when the PUCCH, PUSCH PUSCH containing UCI and the UCI does not contain simultaneous transmission priority to ensuring PUCCH, PUSCH reassurance containing the UCI, the UCI PUSCH without reassurance, Uscj '(VERSION = the ' not (Uscj ( '(Change of Control _ High ()) S) · A (0≤ ((0 - AuCCH (0 - AuSCHj- () (6) However, the present inventors have found that standard only defines a serving cell for uplink power control channel or multi-carrier technology at primary and secondary serving cell the serving cell (Secondary Serving Cell) uplink transmission power control channel. However, with the development of small base stations are present in Rel-12 will be how the scene of small base stations within a macro base station coverage.

More typical non-ideal, ie larger transmission delay and limited transmission capacity. The current standard does not take into account these scenarios, the user equipment uplink power control channel.

Due to the small base stations and macro base stations belonging to different eNB, and the non-ideal circuit, the uplink control signal is more suitable for transmitting in each eNB uplink channel. Well, that may appear on a small base station and on the macro base station transmit PUCCH simultaneously; or send containing the UCI PUSCH on a small base, and in the macro base station also sends containing the UCI PUSCH, or on a small base station transmits contain the UCI PUSCH , and sent on the macro base station PUCCH; or send in a small base station PUCCH, on a small base station transmits contain the UCI PUSCH; or send PUCCH and PUSCH contains the UCI on a small base, and in the macro base station transmits only PUCCH; or send in the macro base station containing PUCCH and PUSCH contains the UCI, but only on a small base station transmits PUCCH; or send in a small base station Get PUCCH and contain the UCI PUSCH, and in the macro base station transmits only contain the UCI PUSCH; or send PUCCH and PUSCH contained UCI in the macro base station, but on a small base station sends only contain the UCI PUSCH; or on a small base station send PUCCH and PUSCH contains the UCI, the macro base station can transmit the PUCCH and PUSCH contains UCI; for PUCCH, PUSCH combinations containing the UCI and the UCI without the PUSCH, I am not tired. It is worth noting that the above only macro base station and the user equipment and base station maintains a small connection schematic, but the present invention is not limited thereto. The following scene only 5 to 7 of the diagram, for example, embodiments of the present invention will be described in detail. Example 1 Power control method of the present invention to provide an uplink channel, is applied to at least two cells and keep the user connected equipment side. FIG 8 is a flowchart of a power control method according to an embodiment of the present invention, as shown in Figure 8, the method comprising: At step 801, the user equipment for at least two cells containing the UCI sent uplink channel signal in the same sub-frame, at least two cells of the upstream channel to prioritize; Step 802, the user equipment based on the results of the prioritization of at least two cells of the upstream channel power allocation, or upstream channel selection. In the present embodiment, at least two cells as shown in Fig 5-7 may be formed by a macro base station and the small base station. For example, may be one or more small cell and small cell base station of a macro macro base stations (Macro eNB) under (Small Cell eNB) under, it can be a primary cell in a dominant position and one or more subordinate times a cell can also be a plurality of small cells, and so on. The present invention is not limited only to these two cells as an example, the case of more than two cells is similar. In the present embodiment, it may have a non-ideal circuit (Non-Ideal Backhaul) between the at least two base stations of the cells, but the present invention is not limited thereto. For eNB and belong to the same cell over a plurality of circuit connection, it can be processed according to the prior art. In this embodiment, the same sub-frame may refer to a sub-frame number of the same sub-frame, but the present invention is not limited thereto. For example, if two cells are not synchronized, a sub-frame of the same is not limited to the sub-frame number, but may be along the time dimension of a sub-frame length is the same period of time. In this embodiment, prior to step 801, the user device may generate ACK / NACK feedback downlink signal received; or based on periodic CSI configured cycle and offset, or CSI trigger indication based on the received aperiodic , or depending on the desired upstream service resource request, generates a corresponding uplink control information. After step 802, the user equipment according to uplink channel power allocation results, or the results of the upstream channel selection, transmit an uplink channel signal. About generation and upstream channel UCI Specific content transmission, etc., you can refer to the prior art. In the present embodiment, in order to PUCCH for example, that at least two cells in the uplink channel include: PUCCH for the PUCCH and another cell for a cell. You may first need to determine whether the user equipment in the same sub-frame, transmitting PUCCH on a serving cell, but also in the other services send PUCCH cell. In step 801, at least two cells uplink channel prioritization may include: Depending on the type PUCCH included in UCI and / or at least two cell types or index number, to determine the PUCCH priority. In one embodiment, when the user equipment needs in the same sub-frame, transmitting a signal on a PUCCH serving cell, the cell also sends another service PUCCH signal, power distribution can be determined according to the type carried by the UCI PUCCH priority. Wherein, PUCCH can be carried ACK / NACK feedback, scheduling request (SR, Schedule Request) or periodic channel state information (CSI, Channel State Information) report. It can be used to prioritize one of the following conditions or a combination of: Condition 1: Contains an ACK / NACK PUCCH priority higher than the CSI comprises a periodic PUCCH priority; Condition 2: Including the SR PUCCH PUCCH contain priority higher than the priority of the periodic CSI; Condition 3: Including the ACK / NACK PUCCH priority higher than the SR PUCCH contain priority. In addition, the method may further comprise: Condition 4: PUCCH contain different types of periodic CSI prioritize. Wherein periodically reported CSI can be a variety of combinations or one of the following: · Type 1: report supports CQI feedback for the UE selected sub-bands (user feedback comes selective CQI) • Type la: report supports subband CQI and second PMI feedback (CQI sub-band, and the second PMI) • Type 2, Type 2b, and Type 2c: report supports wideband CQI and PMI feedback (宽带 CQI和 PMI) • Type 2a: report supports wideband PMI feedback (宽带 PMI) • Type 3： report supports RI feedback (秩 RJ ) • Type 4: report supports wideband CQI (宽带 PMI) · Type 5： report supports RI and wideband PMI feedback (RI和宽带 PMI) 參 Type 6： report supports RI and PTI feedback (RI禾口 PTI) Wherein, PUCCH contain different types of CSI reporting period can be determined by priority: highest priority: Types 3, 5, 6, 2a Second priority: Types 2, 2b, 2c, 4 Third priority: Types 1, la Further, when the PUCCH same priority contains periodic CSI can be further prioritized according to the CSI Process ID size. Such as CSI Process ID smaller the lower the priority. It is worth noting that the above conditions can be used alone, or several of which can also be used in combination, all or in combination, but the present invention is not limited thereto. In this embodiment, when the PUCCH contain two or more of the UCI, the PUCCH may be determined according to the priority of two or more of the UCI priority. Specifically, if a PUCCH carries in more than one type of UCI, then comparing multiple PUCCH priority to compare against each PUCCH highest priority UCI; if the highest priority UCI priority the same, compared, and so on according to each of the second PUCCH priority UCI. For example, PUCCH 1 on a cell carries ACK / NACK and periodic CSI, PUCCH 2 on another cell carries SR, since cell 1 on the highest priority ACK / NACK 2 on the highest priority SR than cell higher priority can be judged PUCCH cell 1 on a higher priority than the PUCCH cell 2 on the priority. In another embodiment, when the user equipment needs in the same sub-frame, transmitting PUCCH signals on a serving cell, and transmitting PUCCH signal on another serving cell can be determined based on the power of each cell index number / type assigned priority. Among them, a cell can mainly serving cell, the serving cell for the other times serving cell. Alternatively, a cell-based services, all other cells as subordinate primary or secondary serving cell the serving cell. Alternatively, a cell of a macro cell, another cell of the small cell. Or based on some sort of guidelines cells, such as bearer control Plane made cell signal takes precedence over user plane bearer cell signal priority, and so on. In the present embodiment, prioritizing one of them can be used or a combination of the following conditions: a priority for the main cell PUCCH for times greater than the priority of the cell PUCCH; for macrocell PUCCH priority higher than for small cell PUCCH priority; priority for the index number of small cells is greater than the priority of the PUCCH for large cell index number of the PUCCH. It is worth noting that the above conditions can be used alone, or several of which can also be used in combination, all or in combination, but the present invention is not limited thereto. In another embodiment, when the user equipment needs in the same sub-frame, transmitting PUCCH signals on a serving cell, and transmitting PUCCH signal on another serving cell, according to the type PUCCH carried UCI and each cell the index number / type of joint is determined power allocation priority. Specifically, there can be prioritized according to the type of PUCCH UCI carried, if the same priority is determined based on the priority of the cell index number / type. For example, if the user equipment needs to send a macro base station on a periodic carrier reported CSI the PUCCH, the base station transmits a small carrying ACK / NACK in the PUCCH, according to the ACK / NACK period is higher than the reported CSI conditions, determine the small base station the PUCCH highest priority. As another example, if the user equipment needs to be sent on the macro base station carries PUCCH periodic CSI report on a small base station 1 transmits carrying the ACK / NACK PUCCH, on a small base station 2 transmits PUCCH carries a periodic CSI report, and the periodic CSI report and on the same type of macro base stations, for example, are type 3 (type 3). According to ACK / NACK reporting higher CSI cycle conditions, to determine the PUCCH 1 on a small base station with the highest priority; and according to the macro base station forming a cell is better than the small cell base station forming conditions, determine PUCCH macro base station on the first priority Second, while PUCCH 2 on the small base station has the lowest priority. In particular, it can be prioritized based on cell index number / type, if the same priority is prioritized according to the type of PUCCH UCI carried. For example, if the user equipment needs to be sent on the macro base station carries PUCCH periodic CSI report on a small base station transmits carries an ACK / NACK PUCCH; according to the macro base station forming a cell is better than the small cell base station forming conditions, PUCCH determine the highest priority on the macro base station. It is worth noting that the above only schematically illustrates at least two cells PUCCH how to prioritize, but the present invention is not limited thereto, and can identify specific priority determination mode according to the actual situation. After making the above prioritization, multiple PUCCH case with the same priority can exist. For the following transmission power of the user equipment limited circumstances, for PUCCH prioritized after the allocation of transmission power will be described. In one embodiment, step 702, based on the result of the prioritization of at least two cells of the upstream channel power allocation, it may include: one or more higher priority PUCCH allocated power and have a residual power the case will be assigned to the remaining power of a next priority or more PUCCH; Specifically, when the user equipment is determined in the same sub-frame needs to send a signal on a PUCCH serving cell, but also in other signal transmission PUCCH serving cell, the user equipment transmission power and may exceed the maximum transmission power dish, then in the said subframe signal for PUCCH power allocation. According to a predetermined priority for each cell on the PUCCH sort. High priority PUCCH priority in the allocation of power and reduce the transmission power of a relatively low priority signal transmission priority to ensure a relatively high signal. In the following description, the remaining transmission power is the maximum output power of the user equipment transmission power by subtracting the allocated transmit power remaining after. That is the highest priority PUCCH can follow the formula (3) calculation, assuming the highest priority PUCCH transmission on the j-th carrier / cell, r I Z I = PUCC" (3) If the same priority PUCCH have more than one, ∑w(i)-P¥l]CCU>c(i)k . 10 lo io V CMAX,c (0 PUSCH [l01og 10 (p USCHjC ( If the same priority PUSCH have more than one, S.

If the highest priority PUSCH power has not yet reached the maximum transmission power of the user equipment ^ dish, you can think that the second priority of the PUSCH allocated power, assuming that the second priority of the PUSCH transmitted on the first carrier c / cell, P C (i) = m (P C (i), (P CM4x (i) - P K \ / J C ≠ K (13) and so, if in addition to the lowest priority PUSCH alia the power of PUSCH and have not yet reached the maximum transmit power of the user equipment dish, you can think that lowest priority PUSCH power distribution, assuming the lowest priority PUSCH transmitted on the first carrier d / cell, PUSCH ^ (0 (0 _ ^ PUSCH (0 _ ^ PUSCH (0 - ? ^ ≠ ... ≠ C ≠ J (14) If the lowest priority PUSCH have more than one, ∑ H PpuscH (0≤ ( (0 - PpuscH (0 - HuscH (0 -… ·)，…≠ c≠ ( 15 ) d j In the above manner is to determine whether the highest priority PUSCH can transmit full power still exceeds the maximum transmission power of user equipment; if exceeded, for the highest priority of all the PUSCH equal power allocation, other lower-priority PUSCH not send; if not exceed, the highest priority is to ensure full power to send PUSCH. If there is a surplus of power, then to see whether all PUSCH second highest priority can transmit full power still exceeds the maximum transmission power of user equipment; if exceeded, all times PUSCH high priority will be equal power allocation, other lower priority level PUSCH not send; if not exceeded, the second highest priority to ensure the full power of PUSCH transmitted. If there is a surplus of power, continue to the next priority PUSCH power distribution. And so on. In one embodiment, the results of prioritization of at least two cells of the upstream channel power allocation, may include: the results of prioritized transmission power PUSCH are weighted according to weights power for each PUSCH distribution. Specifically, the various priorities were done PUSCH power distribution, high priority PUSCH ensure relatively high power, low priority PUSCH ensure relatively low power. Through the above method, when you need to send the same PUSCH sub-frame simultaneously on different service area, multiple PUSCH power allocation, thereby reducing the transmission power of the user equipment to solve the sub-frame in the same cell in different services while the sum of the transmission power may result when transmitting PUSCH greater than the maximum output power configuration problem. Example 3 Power control method of the present invention to provide an uplink channel, is applied to at least two cells and keep the user connected equipment side. In this embodiment, for at least two cells PUCCH and PUSCH as an example, the same content as in Example 1 or 2 is omitted. Among them, carrying two cell PUSCH and PUCCH, which can be the same cell type under different base / index number, for example, they are the primary cell of the macro base station at carrying PUCCH, the small cell base station under the main bearer PUSCH, or the macro base station primary cell under bearer PUSCH, the main cell of small base stations under the bearing PUCCH; also be cells of different types of different base stations under / index number, for example, are the primary cell macro base station under bearer PUCCH, secondary cell carrying the small base station under PUSCH, or secondary cells under the macro base station carrying PUSCH, the small cell base station under the main bearing PUCCH; eNB under the same or different cell types / index number. However, the present invention is not limited thereto. In this embodiment, it is assumed user equipment can support PUSCH and PUCCH transmitted simultaneously on the same or a different carrier, and does not distinguish whether on the same or a different carrier. That does not exist only support sending on the same carrier simultaneously PUSCH and PUCCH, and does not support sending PUSCH and PUCCH on different carriers; or does not exist only support sending PUSCH and PUCCH on different carriers, but not supported on the same carrier simultaneously transmits PUSCH and PUCCH. In this configuration, if simultaneously transmit the PUCCH and PUSCH, the following combination (with two cells as an example): (1) for cell 1 has no PUCCH and PUSCH, PUCCH for cell 2 without having PUSCH, such a case has been described in Example 1. (2) for cell 1 has no PUCCH and PUSCH, PUCCH and PUSCH for having a cell 2. In the case of the cell that is hosted on PUCCH 2 comparing the cell 1, described in Example 1 has been implemented. In this description is only relations on PUCCH PUSCH 2 and 1 on cell-cell, for example, it can be divided into the following categories: PUCCH 1 cells carrying ACK / NACK, PUSCH carrying cell 2 of the periodic / aperiodic CSI; cell PUCCH 1 carrying SR, PUSCH carrying cell 2 of the periodic / aperiodic CSI; PUCCH 1 cells carrying periodic CSI, PUSCH carrying cell 2 of the periodic / aperiodic CSI. (3) having a cell 1 for PUCCH and PUSCH, PUCCH and PUSCH for having a cell 2, cell 1 and the situation is hosted on 2 cell PUCCH comparison, described in Example 1 has been implemented, and that is hosted on 2 cell 1 and cell PUSCH were compared, it has been described in Example 2. Relationship PUCCH and cell 1 on the cell 2 on PUSCH, the above (2) in the cell 1 having PUCCH without PUSCH, the relationship between cell-cell having a PUCCH and PUSCH when 2 PUSCH 2 on PUCCH and the cell 1 on the same . For the following two cases will be described. In this embodiment, at least two cells in the uplink channel comprises: for a cell PUCCH and PUSCH for another cell; and at least two cells in the uplink channel prioritization may include: according to the uplink channel included type of UCI, the type of at least two cell types or index number, and the upstream channel in which one or a combination, to determine the priority of the uplink channel. In one embodiment, when the user equipment needs in the same sub-frame, transmitting a signal on a PUCCH serving cell transmits PUSCH signal on another serving cell, power distribution can be determined according to the type PUCCH or PUSCH carried by the UCI priority. In particular, prioritization may be used for the following conditions in which one or a combination of: contains ACK / upstream channel NACK of priority higher than contain uplink channel periodic CSI priority; contain SR upstream channel priority higher than containing priority upstream channel periodic CSI; and contains ACK / upstream channel NACK of priority higher than the uplink channel comprises the SR priority; contain SR upstream channel priority level greater than the uplink channel comprises aperiodic CSI's priority ; priority aperiodic CSI contains the upstream channel is greater than the upstream channel contains periodic CSI's priority. In addition, the method may further comprise: a periodic CSI upstream channel contains different types prioritize, how you can sort Reference Example 1. Alternatively, the upstream channel contains different types of aperiodic CSI prioritize, how you can sort Reference Example 2. In addition, when the uplink channel comprises a periodic CSI of the same priority can be further prioritized according to the CSI Process ID size. Alternatively, when the aperiodic CSI contains upstream channel the same priority can be further prioritized according to the CSI Process ID size. In the present embodiment, when the uplink channel comprises two or more of the UCI, may also be used to determine the priority of the uplink channel according to two or more of the UCI priority. Specifically, if a PUCCH carries more than one type of uplink control signal, in comparison PUCCH / PUSCH when the priority, you can compare against PUCCH highest priority UCI, the UCI if the highest priority priority the same level, and then compares the PUCCH and so on according to a second priority UCI. For example, PUCCH 1 on a cell carries ACK / NACK and periodic CSI, PUSCH 2 on another cell carries the aperiodic CSI, since cell 1 on the highest priority ACK / NACK ratio on cell aperiodic 2 CSI higher priority, PUCCH can determine the priority of the cell 1 is higher than the cell 2 on PUSCH. In another embodiment, when the user equipment needs in the same sub-frame, is sent on a serving cell PUCCH signal transmitting PUSCH signal on another serving cell, power allocation may be determined according to the priority of at least two cell types or index number. In particular, prioritization may be used for the following conditions in which one or a combination of: a priority for the main cell upstream channel is greater than the priority for secondary cell uplink channel; for upstream channel macrocell priority higher than for small priority cell uplink channel; priority for the index number of small cells upstream channel is greater than the index for the large number of cell I bow upstream channel priority. In another embodiment, when the user equipment needs in the same sub-frame, is sent on a serving cell PUCCH signal transmitting PUSCH signal on another serving cell, power allocation may be determined according to the type of priority of the uplink channel. Specifically, PUCCH PUSCH may be greater than the priority of the priority. Type UCI in another embodiment, when the user equipment needs in the same sub-frame, transmitting a signal on a PUCCH serving cell transmits PUSCH signal on another serving cell, can carry according to the PUCCH or PUSCH and at least two cell types or index number, to determine a joint power allocation priority. In another embodiment, when the user equipment needs in the same sub-frame, is sent on a serving cell PUCCH signal transmitting PUSCH signal on another serving cell, according to the type and the type of UCI upstream channel PUCCH or PUSCH carried to jointly determine the power allocation priority. In another embodiment, when the user equipment needs in the same sub-frame, is sent on a serving cell PUCCH signal transmitting PUSCH signal on another serving cell, according to the type of the uplink channel and at least two cell types or index number, to determine a joint power allocation priority. In another embodiment, when the user equipment needs in the same sub-frame, transmitting a signal on a PUCCH serving cell transmits PUSCH signal on another serving cell, according to the type PUCCH or PUSCH carried by the UCI, the uplink type channel and at least two cell types or index number, to determine a joint power allocation priority. These are only a schematic illustration of the at least two cells PUCCH / PUSCH how to prioritize, but the present invention is not limited thereto, and can identify specific priority determination mode according to the actual situation. After making the above prioritization, there can be multiple PUCCH / PUSCH have the same priority situation. For the following transmission power of the user equipment limited circumstances, for PUCCH priority sorted / PUSCH how to allocate transmission power will be described. The case of the high priority of one or more upstream channel allocation power, and have residual power: In one embodiment, the results of prioritization of at least two cells of the upstream channel power allocation, specifically including the remaining power is assigned to one or more of the priority of the next upstream channel. Specifically, when the user equipment is determined in the same sub-frame needs to send PUCCH on one or more of the serving cell sends PUSCH on another one or more service areas, and the transmission power of the user equipment may exceed the maximum transmission power ^ dish , then in the sub-frame signal for PUSCH and PUCCH signal power allocation. According to a predetermined priority for PUSCH / PUCCH on each cell to sort. High priority uplink channel can be preferentially allocated power and reduce the transmission power of a relatively low priority signal transmission priority to ensure a relatively high signal. In the following description, the remaining transmission power is the maximum output power of the terminal equipment allocated by subtracting the transmission power of the transmission power remaining after. (3) calculation that is the highest priority PUCCH can follow the formula, or the highest priority PUSCH can follow the formula (1) calculations. If the same priority PUSCH / PUCCH have more than one, the same priority with the same power allocation weights. The second highest priority, and if after a high priority uplink channel assignment complete power, the remaining transmission power is still greater than zero, the remaining transmission power allocated to the highest priority of the upstream channel. For example, to determine whether or not the highest priority of the uplink channel may be full power to send still exceeds the maximum transmission power of the user equipment; if exceeded, then the highest priority of all upstream channel equal power allocation, other lower-priority upstream channel Do not send; if not exceed, the highest priority is to ensure that the uplink channel transmitting at full power. If there is a surplus of power, it is determined that the second highest priority of all upstream channel whether full power to send still more than a user device the maximum transmit power; if it exceeds, then the second highest priority of all upstream channel equal power allocation, other lower priority does not transmit an uplink channel; if not exceeded, the second highest priority to ensure the uplink channel transmitting at full power. If there is a surplus of power, continue to the next priority upstream channel power allocation. And so on. In another embodiment, the results of prioritization of at least two cells of the upstream channel power allocation, may include: the results of prioritization of the transmission power of the uplink channel are weighted according to the weights for each uplink channel power allocation. Specifically, the various priorities are upstream channel power allocation, high priority upstream channel to ensure a relatively high power, low priority upstream channel to ensure a relatively low power. Through the above method, when you need to send in the same sub-frame PUSCH and PUCCH on different serving cell simultaneously, a plurality of PUSCH / PUCCH power allocation, thereby reducing the transmit power of the terminal device, resolved in the same subframe at the same time send PUSCH and PUCCH different services on the internal cell total transmit power may lead to greater than the maximum output power configuration problem. Example 4 On the basis of Example 1, 2, 3, the embodiment of the invention of a power control method for uplink channel will be further explained. In this embodiment, an embodiment can be 1, 2, 3 together applied. Wherein two embodiments may be performed in the embodiment; embodiments or all three embodiments. For example, Example 1 and Example 3 may be implemented together. If the send PUCCH1 on cell 1 and contains the UCI PUSCH (PUSCH 1 with UCI), send PUCCH2 on cell 2, respectively, related to the comparison and PUCCH2 PUCCH 1, as well as the comparison PUCCH2 and PUSCH1. Suppose, PUCCH1 carrying ACK / NACK, PUSCH1 carrying aperiodic CSI, PUCCH2 bearing cycle CSI; so, according to a way of Example 1 and Example 3, can be preferentially allocated to PUCCH1 power; if there is a surplus power can be allocated to PUSCH1; if there is a surplus of power redistribution to PUCCH2. As another example, the embodiments may be 1, Example 2 and Example 3 together. If the send PUCCH 1 and PUSCH1 on cell 1 with UCI, cell transmits PUCCH2 2 and PUSCH2 with UCI; respectively, and to compare Compare PUCCH1 and PUCCH2, more PUCCH1 and PUSCH2, more PUCCH2 and PUSCH1 of PUSCH1 and PUSCH2 of. Suppose, PUCCH1 carrying ACK / NACK, PUSCH 1 carrying aperiodic CSI, PUCCH2 carrying ACK / NACK, PUSCH2 bearing cycle CSI. Then, according to Example 1, Example 2, and one of the ways of Example 3, and the PUCCH PUCCH2 1 may have the same highest priority (if only according to the type of UCI, and not on the type of cell sorting), followed PUSCH1, the minimum is PUSCH2. Then the priority (no decrease) as PUCCH1 PUCCH2 and distribution power; if there is a surplus of power is allocated to PUSCH1; if there is a surplus of power redistribution to PUSCH2. As another example, assuming only Example 1 and Example 2 in the effective implementation of the program, regardless of the implementation of the program in Example 3. That PUSCH and PUCCH comparison, only according to the prior art, PUCCH carries a higher priority than the priority of the UCI PUSCH, PUSCH carrying the UCI does not carry a higher priority than the UCI on PUSCH. So, if sent PUCCH1 on cell 1 (containing the ACK / NACK) and PUSCH1 with UCI (contains aperiodic CSI), send PUCCH2 2 cells (with periodic CSI); the PUCCH1 the highest priority, followed by PUCCH2, PUSCH1 priority lowest. In addition, if the user equipment can transmit the PUCCH and PUSCH on different carriers at the same time, but can not be transmitted on the same carrier simultaneously PUCCH and PUSCH; PUSCH and PUCCH is different carriers priorities can be sorted according to UCI type, or may be according cell / carrier number sorting, or may be sorted according to the uplink channel type. Among them, the different types of upstream channel can be sorted, Upstream channel parameter contains ACK / NACK of the uplink channel> SR contains upstream channel> contains CSI • Includes upstream channel of aperiodic CSI> CSI uplink channel comprises the period And uplink channel includes periodic CSI different types of reports can be sorted, you can not sort 1-3 in the same specific power allocation method of Example, no longer tired. Through the above method, when you need to send in the same sub-frame PUSCH / PUCCH on different serving cell simultaneously, a plurality of PUSCH / PUCCH power allocation, thereby reducing the transmit power of the terminal device, resolved in the same subframe while simultaneously transmitting PUSCH / PUCCH different services on the internal cell total transmit power may lead to greater than the maximum output power configuration problem.
