Title: Method deactivating the secondary cell, and a communication system means

FIELD

[0001]

Embodiment of the invention relates to communication technologies, and in particular relates to activate one of the secondary cell method, apparatus and a communication system.

Background technique

[0002]

Currently, when a user equipment (UE, User Equipment) required range of Carrier Aggregation (CA, Carrier Aggregation) when the capacity of the base station considering CA capabilities of the UE, the UE selects an available carrier, and through radio resource control (RRC, Radio Resource Control) this message will be configured for the UE cell secondary cell (SCell, secondary cell).

[0003]

For timeliness, if deemed configure the SCell can be immediately used for data transmission; then consider resource efficiency, the SCell when not in use, need to remove the SCell, UE no longer transmit data using resources of the SCell; if need this area again when data transmission is required through the RRC re-configuration message to the cell SCell.

[0004]

Considering the frequent, but short duration and the business volume of business types, such frequent configure / delete behavior SCell will consume a lot of RRC message; at the same time, poor timeliness RRC message, and then by if needed RRC configuration message SCell, may not be sufficient to meet the timeliness of such services. Conversely, if the RRC message in order to save operational effectiveness and guarantee performance, so this has been a SCell cell, even if no traffic transmission, then the resource can not be fully utilized, spectrum utilization rate, cell throughput decreases.

[0005]

Therefore, for the SCell introduced a new status: active or the inactive state. UE only listens SCell active state, data transmission is performed only on the SCell active state. When the base station is configured SCell available CAUE, the base station and the UE default SCell in the deactivated state. When desired, the base station control element (CE, Control Element) activation by a medium access control (MAC, Media Access Control) SCell put this status, if by this SCell deactivation MAC CE is placed in a deactivated state.

[0006]

In some cases, deactivation of a SCell deactivation MAC CE transmission may fail, so that the base station SCell in the deactivated state, and the UE in an active state that the SCell; UE may send an uplink transmission of the UE in the autonomous SCell , such as sounding reference signal (SRS, sounding reference signal), which may be an interference to other uplink transmission, and not conducive to energy conservation. For this reason, the introduction of self-deactivation mechanisms UE.

[0007]

That is, in order to unify the UE and the base station understanding of the secondary cells activated state, introduced UE autonomously deactivated, i.e. each secondary cell to maintain a deactivation timer. When the base station activates a SCell by activation MAC CE, the base station and the UE at the same time that the SCell is activated, and starts a deactivation timer for the SCell; CE when the successful transmission or an associated deactivation MAC SCell deactivation timer expires, UE the base station and think this SCell is deactivated.

[0008]

If authorization is received indicating the uplink (Uplink grant) on the downlink assignment or activation of the SCell (Downlink assignment) physical downlink control channel (PDCCH, Physical Downlink Control Channel), or if the received PDCCH scheduling the SCell serving cell in other , including downlink assignment and uplink grant, the UE to restart with the associated SCell deactivation timer.

[0009]

When the UE based on business needs, a SCell no need, the base station may deactivate the SCell; even if the UE does not receive the deactivation MAC CE, the base station does not schedule the SCell long period of time, not transmitting the PDCCH on the SCell then by deactivating the timer, the UE SCell can be self-deactivation.

[0010]

Based on UE autonomous deactivation mechanism, can be appropriately maintained substantially active state of the secondary cell of the CA UE. Although the base station and the UE maintain a deactivation timer for each SCell, but the values ​​of these timers are the same, provided by the base station to the UE RRC configuration message, if the default timer value, is applied infinite value.

[0011]

On the other hand, the current LTE system, the UE for carrier aggregation, only the primary cell arranged on the (PCell, Primary Cell) physical uplink control channel (PUCCH, Physical Uplink Control Channel), almost all cells in all of the uplink control information (UCI, Uplink Control Information) PUCCH on PCell have been uploaded to the base station (e.g. eNB).

[0012]

As new business needs, the number of downlink carriers carrier aggregation more and more, taking into account the user equipment (including non-polymeric carrier with carrier aggregation user equipment) more and more, there is a problem UCI is only transmitted on the PCell . For load UCI transmission, in addition to transmission of the PUCCH on the PCell, the base station may also be capable UE has UL CA select one SCell, for transmitting PUCCH. Thus, the PCell PCell associated UCI transmission, the PUCCH carries SCell UCI transmission on the SCell, the SCell other UCI by a base station disposed on the PCell transmission or a transmission arranged on the SCell carrying the PUCCH.

[0013]

I.e., the current carrier aggregation, the presence of two PUCCH carries a serving cell, one of which is the PCell, SCell other is carrying the PUCCH. PCell and SCell all common control information through the uplink PUCCH transmission PCell cell composition of the primary PUCCH packet; PUCCH carries all common and all the SCell SCell PUCCH transmission control information through the uplink PUCCH SCell secondary cell composition group. Primary and secondary packet cell PUCCH PUCCH PUCCH referred to as a cell packet cell packet.

[0014]

It should be noted that the above description of the technical background for convenience only technical solution of the present invention will be clear and complete instructions, and to facilitate the understanding of the skilled in the art and forth. Just because these solutions are set forth in the background section of the present invention that the above technical solutions known to those skilled in the art.

detailed description

[0060]

Referring to the drawings, the following description, the foregoing and other features of the present invention will become apparent. In the description and drawings, particular embodiments specifically disclosed embodiment of the present invention, which shows the principles of the invention may be employed from the first embodiment, it is understood that the present invention is not limited to the described embodiments, on the contrary, the present invention includes all modifications falling within the scope of the appended claims, modifications and equivalents thereof.

[0061]

The following example presents a scenario to occur specify under what circumstances the following questions: "carry PUCCH base believes the SCell is active, while the UE think this SCell in a deactivated state."

[0062]

1 is a view of an example of a scene embodiment of the present invention. As shown in FIG. L, at a transmission time interval (TTI, Transmission Time Interval), the base station through the PDCCH is transmitted on 1 SCell, scheduling SCell 1 or other cross-carrier scheduling SCell. But PDCCH transmission failure, UE does not receive the PDCCH. Thus only the base station associated SCell 1 and restart a deactivation timer, and the UE does not restart the timer.

[0063]

For example, at time t1, the base station that SCell 1 and SCell 2 are active, their deactivation timer in operation; SCell 1 and the UE that has been deactivated, Tl times out; SCell 2 simultaneously active, T2 is still running .

[0064]

In this case, the base station may schedule downlink data transmission SCell 1/2. In the case of self-scheduling, by the base station from the scheduling SCell 1 SCell 1 failed because the UE considers SCell 1 deactivated, without listening SCell 1. In addition, the base station may transmit a downlink allocation by PDCCH SCell 2, 2 SCell scheduling downlink transmissions, but it does not work, because the feedback on the downlink data transmitted on the PUCCH needs to be sent SCell the SCell. 1, and cognition is common to activated SCell can not transmit uplink control information. For cross-carrier scheduling, the base station 1 SCell cross-carrier scheduling by SCell 2 failed, because the UE does not listen to it that has been deactivated SCell 1; or the base station 1 can not be achieved by cross-carrier scheduling SCell SCell 2, because the UE I think SCell 1 is deactivated.

[0065]

The problem actually exists in the previous version of carrier aggregation in, but because it involves only a single SCell, no effect on the transmission of other SCell, so you can wait for the base station's own testing found and processed. However, after the introduction of PUCCH on SCell, if this problem occurs on SCell carry PUCCH, then in addition to the SCell, for uplink transmission of control information for all downlink SCell will not be able to work through this PUCCH SCell, which It is a serious quality degradation. Therefore, it is necessary to solve this problem.

[0066]

Example 1

[0067]

Deactivation method of the present invention provides a secondary cell, applied to the user equipment, the user equipment is configured with a first carry PUCCH secondary cell does not carry the PUCCH and a second secondary cell, the secondary cell and the first transmitting the uplink control one or more second secondary cell composition information packet through said secondary cell PUCCH PUCCG.

[0068]

FIG 2 is a schematic diagram to the embodiment of the activation method of the present invention, shown in Figure 2, the method comprising:

[0069]

Step 201, the user equipment determines a second secondary cell according to any of the secondary cell PUCCH packet, indicating deactivation timer is restarted or the channel quality report is transmitted;

[0070]

Step 202, the user reboot carrying first secondary cell PUCCH associated deactivation timer.

[0071]

In the present embodiment, the PUCCH may carry SCell (first secondary cell) introducing a new trigger mechanism to activate the timer to restart.

[0072]

In the case of one embodiment, in the secondary user equipment of any one of the second packet cell PUCCH secondary cell deactivation timer is restarted, and restarting the PUCCH carries a first cell associated with a secondary deactivation timing of device.

[0073]

Specifically, the user equipment may determine whether the received downlink assignment or uplink grant indicating on said second secondary cell of any one of the PDCCH, or the received other services in the scheduling cell according to any uplink grant indication or a second secondary cell assignment of downlink PDCCH. Under these circumstances, restarting the second secondary cell of any one of deactivation timer; and restart PUCCH carrying first secondary cell associated deactivation timer.

[0074]

In another embodiment, the user equipment in any case where the secondary cell packet PUCCH secondary cell a second channel quality indication (CQI, Channel Quality Indicator) report is to be transmitted, carrying the first restart the PUCCH secondary cell associated deactivation timer.

[0075]

Specifically, the user equipment may determine whether the received downlink assignment or uplink grant indicating on said second secondary cell of any one of the PDCCH, or the received other services in the scheduling cell according to any uplink grant indication or a second secondary cell downlink assignment PDCCH, or the second secondary cell of any one of whether to transmit a CQI report. Under these circumstances, restarting the PUCCH carrying a first cell associated with a secondary deactivation timer.

[0076]

Thus, as long as the secondary cell PUCCH packet to any one SCell deactivation timer is restarted, or the CQI report is transmitted, then the PUCCH carries associated SCell deactivation timer will be restarted, downlink transmission does not occur in ordinary SCell the situation can not work. This approach ensures that after the introduction of the PUCCH on SCell, carrier aggregation of at least the same performance as before.

[0077]

Seen from the above embodiments, the introduction of a new trigger mechanism for the deactivation timer to restart the PUCCH carrying the secondary cell; Accordingly, the user equipment and the base station does not occur due to the activation mechanism to customize the user equipment caused by the active state of the secondary cell, understand the inconsistencies.

[0078]

Example 2

[0079]

Embodiment to provide a secondary cell of the embodiment of the present invention the activation means, arranged in the user equipment, for example, corresponding to the deactivation method of Example 1, the content of the same embodiment of the present invention is not repeated.

[0080]

In the present embodiment, the PUCCH carries a user device is configured with a first and a secondary cell does not carry a second PUCCH secondary cell, a secondary cell and to transmit a first uplink control information or a plurality of the PUCCH by The second secondary cell composed of the secondary cell PUCCH packet.

[0081]

Figure 3 is a schematic of an embodiment of the present invention, deactivation of the device, as shown in FIG said deactivation apparatus 300 includes:

[0082]

A case where the restart unit 301, any packet in the secondary cell of a second PUCCH secondary cell, the deactivation timer is restarted or CQI reports are transmitted, to restart the secondary cell carrying the first PUCCH associated to activate the timer.

[0083]

As shown, the apparatus 300 may deactivate 3 further comprising:

[0084]

Determination unit 302 determines whether the received downlink assignment or uplink grant indicating on said second secondary cell of any one of the PDCCH, or the received other services in the scheduling cell according to any indication of a second uplink grant or downlink secondary cell assigned PDCCH.

[0085]

In one embodiment, the determination unit 302 determines any of the secondary cell received at a second uplink grant indicating the PDCCH or downlink assignment, or receiving other services in the scheduling cell according to any indication of a second auxiliary cell PDCCH downlink assignment or uplink grant; restart restarting the unit 301 to any of a second auxiliary cell deactivation timer and restart the PUCCH carries a first cell associated with a secondary deactivation timer.

[0086]

In another embodiment, the determination unit 302 determines any of the secondary cell received at a second uplink grant indicating the PDCCH or downlink assignment, or receiving other services in the scheduling cell to the second secondary cell of any one of It indicates downlink assignment or uplink grant PDCCH, or a second secondary cell according to any CQI report transmission; restarting section 301 to restart the PUCCH carries a first cell associated with a secondary deactivation timer.

[0087]

Seen from the above embodiments, the introduction of a new trigger mechanism for the deactivation timer to restart the PUCCH carrying the secondary cell; Accordingly, the user equipment and the base station does not occur due to the activation mechanism to customize the user equipment caused by the active state of the secondary cell, understand the inconsistencies.

[0091]

Step 401, the user equipment to the PUCCH carries a first secondary cell is configured not to run deactivation timer; or the first secondary cell deactivating than the second secondary cell configuration of the timer deactivation timer is greater.

[0092]

In the present embodiment, the PUCCH for carrying SCell, UE may not be provided to customize the activation mechanism.

[0093]

In one embodiment, the PUCCH carries a user equipment to the first secondary cell, deactivation timer is not running; PUCCH does not carry to the second secondary cell, it starts to activate the timer.

[0094]

In another embodiment, a user device, the first secondary cell deactivation timer value is greater than the secondary cell is disposed a second deactivation timer. Specifically, the first secondary cell deactivation timer configured to a value larger than the second deactivation timer of the secondary cell, for example, infinity.

[0095]

That can be introduced different for different SCell deactivation timer value, which carry a PUCCH SCell deactivation timer is set for example to infinity; and other common SCell do not carry PUCCH value, in order to try to reuse the current mechanism can be set the same value. Such a timer value applies only to the base station configured SCell general do not carry the PUCCH.

[0096]

When SCell is activated, start deactivation timer: If this SCell carrying SCell PUCCH, then the default value is infinite; otherwise the SCell is not carrying ordinary SCell PUCCH, then according to the current mechanism, the base station configuration using timers value, if the base station is not configured, the default infinity.

[0097]

However, the present invention is not limited to the value of the secondary cell of the first deactivation timer is infinite, e.g. deactivation timer than the second setting value of the secondary cell may be much larger. A first secondary cell may be, for example, a deactivation timer value can have a maximum value for the timer and the like, may be determined based on the actual value of the specific situation.

[0098]

In the present embodiment, the PUCCH carries SCell deactivating MAC CE only through deactivation, without the presence of the technical problem: "the base station that the SCell is active, but the UE considers the SCell in the deactivated state."

[0099]

Seen from the above embodiments, the PUCCH that carries the secondary cell does not configure the user equipment to customize the activation mechanism; thus, will not be inconsistent with the user equipment to the base station because the user equipment independent activation mechanism of activation state caused by the secondary cell appreciated Happening.

[0100]
