Background technique
[0002]
Introducing LTE (Long Term Evolution) 12th edition small cell (small cell), small cell radio access node is a low power, which work in unlicensed spectrum authorization, may cover a range of 10 meters to 200 meters . It will be widely deployed around the world in the licensed band LTE network deployment. In order to further expand the LTE network capacity to adapt to the rapid growth of demand for data, you can adjust the radio interface and the LTE transmission mechanism so that it can use unlicensed spectrum resources for data transmission. This technique is called the LAA (secondary access authorization) -LTE.
[0003]
From the user's perspective, efficient use of unlicensed spectrum resources so that users can get better quality service. Transparent transmission and improve the user experience unlicensed bands can provide more flexibility to the operator, the operator can also obtain higher benefits from the exploitation of the unlicensed band. This in turn will enable operators to develop more unlicensed spectrum.
[0004]
For example, the 5GHz unlicensed frequency band as the target band, some additional criteria need to be formulated to meet the different needs of different regions. To implement the detection of semi-static, non-reducing interference of IMT (International Mobile Telecommunications) system and other systems such as radar, the DFS (Dynamic Frequency Selection) mechanism is widely used in all areas. LBT (listen before reading the first check) coexistence mechanisms provide flexible and fair and non-IMT IMT different systems. LBT such unlicensed band channel can ensure rapid detection and dynamic channel occupancy. TPC (Transmit Power Control) technology, while not widely used, but the method is still a neighbor cell power limits for leakage.

detailed description
[0029]
It will now be described with reference to the accompanying drawings of embodiments of the present invention. Elements and features of the elements and features described in one figure or one embodiment of the present invention may be illustrated embodiment with one or more other drawings or embodiments described combination. It should be noted that for purposes of clarity, the drawings and the description is omitted irrelevant to the present invention, shown and described are known to those of ordinary skill in the components and processes.
[0030]
1, the wireless communication device 100 according to the present embodiment comprises a processor 110. It is noted that, although the figures shown in the processor 110 as a functional module in the determination unit 111 and a generating unit 113, it should be understood that determining function unit 111 and a generating unit 113 may be by the processor 110 as a whole, to achieve, and not necessarily by the processor 110 in the separate components to achieve practical. Further, while a dashed box in the figure shows a processor 110, however, the communication device 100 may include a plurality of processors, the determination unit 111 may function generation unit 113 and distributed to the plurality of processors to a plurality of processing It is cooperate to perform these functions.
[0031]
Determination unit 111 is configured to determine a communication content to be transmitted to the base station of the user equipment (the traffic) in the unlicensed band and is expected to target the transfer process (transmission schedule).
[0032]
It is noted that, in some examples, only the LAA (Licensed Assisted Access) frequency band to transmit data, the communication with the content of pure data transmission, while in other examples, in addition to the data may also transmit signaling information through the LAA band. Here, the LAA bands usually licensed band is jointly used by carrier aggregation manner, a sample application unlicensed band in a cellular communication system as, in some examples, the unlicensed band resource can be independently (stand-alone ) is used, the present invention is not intended to be limiting.
[0033]
Further, the transmission schedule may be the remaining time of communication content transmission, e.g., data size and the current transmission transfer rate can be estimated by calculating the remaining time of transmission. However, the present invention is not limited thereto, for example, may also be an amount of remaining data to be transmitted to indicate the transmission schedule. As another example, in a case where the user equipment is performed only on the unlicensed band transmitted within a predetermined length of time, the transmission schedule may indicate the passage time has been transferred.
[0034]
Generating unit 113 generates the instruction information on transmission schedule and the indication information added to the communication frame the user equipment to transmit the indication information.
[0035]
According to one embodiment, the generated indication information may be contained for coordination with other communication devices in a broadcast subframe. More specifically, the broadcast subframe may, accordingly, the generation unit 113 may also be information contained in the common channel subframe for other communication device is a common channel subframe physical cell identity of the base station (PCI) coordination, e.g., PCI to indicate implicitly by transmitting a synchronization signal in common channel subframe. In a preferred example, the wireless communication device 100 may indicate information added to the communication frame includes be transferring the content to target unlicensed band transmission, thereby reducing other device detects the object unlicensed band transmission schedule / idle time the complexity. Alternatively, the information may be added to indicate a broadcast subframe without licensed band to be transmitted are transmitted along with the content, wherein, in the sub-frame needs to include the broadcast unlicensed band indication information corresponding to the ID.
[0036]
According to the 3GPP (Third Generation Partnership Project) RAN1 78 meeting to discuss the results, LTE users must follow the discontinuous transmission limited maximum transmission time in an unlicensed band carriers. According to the present invention, when the base station in an unlicensed band for transmission, for example, a periodic signal in the transmission data is added indicating the remaining time to pass, for example, to indicate the transmission schedule other carriers remaining time of the current band transmission, e.g. . Thus, the transmission may be transmitted unlicensed band indication signal broadcast subframe to allow different operators and users of the base station can detect this information to implement coordination / coexistence between different operators use the unlicensed band. For example, a second operator LTE communication system may operate in accordance with a first operator in a LTE communication system on the progress of the transfer of the unlicensed band, the determined remaining within this limited maximum transmission time available transmission time and transmission preparation.
[0037]
According to a particular embodiment, the broadcast subframe is a multicast broadcast single frequency network (MBSFN) subframe.
[0038]
Multimedia Broadcast Multicast Service (MBMS) cellular system multicast, broadcast services, thereby simultaneously providing a multicast, broadcast traffic and unicast traffic in a network. For LTE, the spread of this called MBMS single frequency network (MBSFN), involved in the conventional MBSFN transmission plurality of cells MBSFN transmission frames over a transmission identical (Identical) information specified MBSFN subframe, the user equipment for signal waveforms from a plurality of identical cells, can be considered as a single cell from a received multi-path transmission experienced a single signal, thus it provides the following benefits:
[0039]
Increase the strength of the received signal, the signal energy may be used in particular, received from a plurality of cells between the cells involved in the MBSFN transmission boundary, the terminal;
[0040]
Reducing the interference level, too, the boundary between cells participate particularly in MBSFN transmission, the signal received from the adjacent cell is no longer an interference signal, but the useful signal;
[0041]
Generating the additional diversity against channel fading, since the information received from several geographically separated locations, which are usually such that the overall composite channel exhibits strong time dispersion, or strong frequency selectivity.
[0042]
In the present invention, the inventors subvert the traditional knowledge of the MBSFN transmission, the same is not required to transfer information in a multi-cell multi-cell MBSFN transmission, the user equipment is no longer necessary to transfer the content from multiple MBSFN cell are combined, and each cell design uses MBSFN subframe are each carried in the unlicensed band transmission schedule information, whereby, LTE communication system, a user equipment / or base station can be readily (e.g., a unified set of predetermined frequency and a subframe at a particular transmission resource ) unlicensed band transmission schedule read from a plurality of cells (e.g. MBSFN transmission content managed by different operators), the decoding result based on the MBSFN subframe determining respective cell. This process does not force interaction between the cells, there is no need to design a new sub-frame structure, thus making coordination of unlicensed spectrum between different operators use made simple.
[0043]
Next, the base station estimates the remaining time as the transmission of communication content transmitted progress exemplary way of an example by the transmission schedule MBSFN indication.
[0044]
Suppose the base station estimated transmission time is ten frames and four frame has been transferred, for example, the base station may transmit two frames every instruction signal to indicate a remaining transmission time it needs. For example, when the user or other base stations in the MBSFN detected sequence "11", they can know that the band has three remaining MBSFN subframe, i.e., the base station being transmitted, and six frames to be transmitted. Other base stations can use this information to decide whether to wait until the current access is completed after the transmission band. Further, there may also be added MBSFN PCI information of the base to help distinguish the UE received the cell from which the MBSFN subframe. Wherein the signal indicative of a base station transmission interval may be set depending on the maximum transmission time limit is limited to a different value, for example, when the maximum transmission length is limited in the case of less than 30ms, and each frame can be arranged to send an indication signal.
[0045]
Further, UE, for example such as white list (white list) on the SIB information carriers that PCI with the base station of the present cell through the system information, if the user is not detected in the white list PCI above, the UE may determine whether the PCI belonging to other operators. If the PCI is detected in the white list, it may be determined with the signal from an adjacent carrier. Whereby, UE may feed back the respective detection results to the serving base station for policy decisions coexist in the unlicensed band.
[0046]
Next, with reference to FIG. 2 illustrates a wireless communication device for a base station side according to another embodiment. 2, the wireless communication apparatus 200 according to the present embodiment includes a processor 210, a processor includes a determining unit 211, generating unit 213 and the detection unit 215. Similar determination unit determining unit 211 and a generating unit 213 described above with reference to FIG. 1 111 113 and a generating unit.
[0047]
Detection unit 215 is configured to detect unlicensed band, the estimated available unlicensed band, and a user equipment for selecting one or more candidate bands based on the detection result.
[0048]
The wireless communication apparatus 200 according to the present embodiment further includes a transceiver unit 220, which is configured to inform the user equipment of the selected one or more candidate bands.
[0049]
220 detection unit 215 can be detected by the control unlicensed band transceiver.
[0050]
Next, an embodiment of the present embodiment will be described by way of specific examples. It is understood that the invention is not limited to the details of the following specific examples.
[0051]
In an unlicensed band 5470MHz ~ 5725MHz as an example, the band may be occupied with a radar system or Wi-Fi users. The wireless communication device may be, for example, full-band detector for unlicensed band, and generates a detection result based on the list information unlicensed band may be used, for example, the following Table 1.
[0052]
Table 1: idle channel list
[0053]
[0054]
After generating a list of each base station may transmit the available frequency bands to each information obtained in the unlicensed band requires the user to transmit data. More specifically, the base station may allocate the available band according to the different needs of the user data transmission. For example, a larger user data transmission needs can be preferentially obtained wider unlicensed band resource.
[0055]
Further, according to one embodiment, upon receiving the band information from the base station, the user equipment itself may detect the specific frequency band to reduce interference may cause the current system. The user is detected after the frequency band information corresponding to the feedback information sent to the base station.
[0056]
Typically, the user equipment feedback delay is about 4ms mechanism, although other systems such as WiFi access time of the system is likely to be shorter than 4ms. Therefore, in this period of time the user feedback, it is possible to detect a WiFi device and found that the frequency band currently available, so it is possible to access the WiFi device in 4ms time band. In this case, lead to the LTE base station can not occupy the band or the base station continues to access the resulting two band system conflicts.
[0057]
View of the above problems, according to one embodiment, transceiver 220 is configured to notify a predetermined time period after the user equipment transmits candidate band signal occupying the inner band candidates. For example, the signal may be occupied by beacon (Beacon) signal.
[0058]
Accordingly, in one embodiment of the invention, the wireless communication device for a base station side comprising one or more processors, the processor may include a detecting unit, dispensing unit and a generating unit. A detection unit configured to detect the availability of unlicensed band. Allocation unit is configured based on the availability of unlicensed band corresponding initial unlicensed band allocated to the base station the user equipment. Occupied signal generating unit configured to generate a pilot cell including a base station corresponding to pilot sequence does not contain such data to the respective corresponding non-authorized for unlicensed band, in particular a base station intended to indicate an access band period. Further, the radio communication apparatus according to the present embodiment may further include a transceiver, transceiving device, for example, can be tested in the unlicensed band under control of a processor and transmitting a pilot sequence generated by the processor.
[0059]
Next, an embodiment of the present embodiment will be described by way of specific examples. It is understood that the invention is not limited to the details of the following specific examples.
[0060]
When the base station in an unlicensed band detected idle frequency band assigned to the user and at the same time, which can be transmitted in the frequency band occupied by the periodic signal to prevent other devices that access the user feedback during band. Occupancy signal may be designed, for example, cell-specific reference signals (CRS). From the time domain point of view, there are two signals within a LTE CRS slot. This means that the maximum time interval of the signal CRS is three OFDM symbols, about 200us. As shown in the schematic diagram in FIG. 14, the base station can always send feedback information to the user until receiving a signal occupancy.
[0061]
The transmission can be prevented to a large extent occupied by the signal in the feedback device such as a WiFi access time to improve the access probability of the band in the unlicensed band of the LTE.
[0062]
As described above, according to one embodiment, the user equipment may be detected for a certain frequency band, and transmits the feedback information to the base station. Next, with reference to the embodiment of Figure 3 will be described.
[0063]
3, wireless communication apparatus 300 according to this embodiment includes a processor 310 and a transceiver 320. The processor includes a determination unit 311, generating unit 313, detection unit 315 and dispensing unit 317. Determination unit 311, generating unit 313 and the detection unit 315 described above with reference to FIG. 1 determining unit 111, generating unit 113 and a detection means similar to that described with reference to FIG. 2 215.
[0064]
The transceiver unit 320 is configured to receive a user equipment a detection result of the candidate band. Dispensing unit 317 is configured to determine at least a user equipment assigned to the unlicensed bands target user equipment according to a detection result of the candidate band. In other words, according to this embodiment, may be determined according to the unlicensed band allocated feedback information of the user equipment, or may be determined according to the unlicensed band assigned both to a base station the feedback information unlicensed band detection results and the user equipment .
[0065]
In the case where the allocation is determined according to the unlicensed band of both the base station the feedback information unlicensed band detection results and the user equipment, the detection unit 315 may be configured to obtain a detection result in the case where the user equipment again candidate band detecting candidate frequency bands, and allocating unit 317 may determine the target device assigned to the user based on the user equipment unlicensed bands candidate frequency band and a detection result of the detection unit 315 is detected again result.
[0066]
Next, an embodiment of the present embodiment will be described by way of specific examples. It is understood that the invention is not limited to the details of the following specific examples.
[0067]
The user equipment can indicate, for example, the detection result of the target unlicensed band 2 by the following bit sequence:
[0068]
00: the transmission signal is not detected
[0069]
01: There LTE signal transmission from the same carrier
[0070]
10: there is an LTE signal transmissions from different carriers
[0071]
11: unknown signal transmission from other systems
[0072]
For the case where the base station transmits signals to occupy after allocating frequency bands to the user equipment, the user equipment detects that the channel occupancy time will detect this signal issued by the base station. For the user equipment, if the signal is detected only occupying the present base station, it may be considered that the band is available, a feedback 00.
[0073]
The base station and the user equipment, if the detected signal is initially detected, for example, other base stations transmitted signal CRS, the band may be determined directly unavailable (low probability of this situation, because the base station time of about 4ms only feedback CRS will be sent within the signal, then access will choose to give up or to wait, so this situation simply choose to give access and does not significantly affect the probability of unauthorized access band).
[0074]
In addition, the base station may assign to a user equipment simultaneously two or more target unlicensed band, in this case, the user equipment may detect that these bands are obtained the corresponding feedback information and specifically with a single band detection system a similar situation. The base station according to their joint detection result of the frequency band is determined whether allocated can be used to give the user feedback after the results for the two bands, or only a portion of the frequency band may be used.
[0075]
When two or more base station allocates unlicensed bands to a user, in order to better distinguish between different frequency bands, the channel label may be, for example, as shown in Table 2 below:
[0076]
Table 2: single-user multi-band number
[0077]
[0078]
[0079]
The base station allocates the n channels to a user equipment, the user equipment are detected in the received channel assignment After all the n channels, after all the channel detecting completion of user n detection result of the channel, respectively, to the base station, such as channel 1: "00"; channel 2: "01"; ......; channel n: "11". Each base station independently determines the feedback channel is available and the results of their test results.
[0080]
Examples similar to those described previously, may each represent a detection result of a user equipment and a base station frequency band by the two-bit information sequence, for example, listed in Table 3 below.
[0081]
Table 3: Combined results of the detection
[0082]
[0083]
Depending on the application and combination of requirements, the base station may be based on the detection result according to different criteria to determine the target allocation for the unlicensed band.
[0084]
For example, the band may be allocated in the base station and the user equipment was not detected in the other base station apparatus using the target or unlicensed bands.
[0085]
Alternatively, in the case where only the target is detected using the same according to other base station operators unlicensed band, and the band allocation can be determined. In this case, the use of the target frequency band may coordinate with other base stations, will later be described in conjunction with specific embodiments.
[0086]
Further, the case of one embodiment, the transmission schedule includes information indicative of the signal from another base station can be expected available time corresponding unlicensed band based on the indication information, the corresponding band to use or detect the appropriate time.
[0087]
4, the wireless communication apparatus 400 according to the present embodiment includes a processor 410 and a transceiver 420. The processor 410 includes a determination unit 411, generating unit 413, a detection unit 415 and the unit 417 is expected. Determination unit 411, the detection unit described in the second generation unit 413 and the detection unit 415 previously described with reference to FIG. 1 determining unit 111, generating unit 113 and the reference view similar to 215, similar to the transceiver means 420 previously described with reference to FIG 2 a transceiver apparatus described 220 .
[0088]
Expected unit 417 is configured as an estimated available time corresponding unlicensed band based on transmission schedule information indicating a signal detected in the other base stations.
[0089]
Next, with reference to FIG. 5 illustrates an embodiment of the target frequency band used in coordination with other base stations.
[0090]
5, the wireless communication device 500 of the present embodiment includes a processor 510 and a transceiver 520. The processor 510 includes a determination unit 511, a generating unit 513, detection unit 515 and a coordination unit 517. Determination unit 511, the detection unit described in the second determining unit 111 explained in the first generation unit 513 and detecting unit 515 previously described with reference to FIG, generating unit 113 and the reference view similar to 215, 520 previously transceiver reference to a transceiver device 520 illustrated in Figure 2 is similar to .
[0091]
Coordination unit 517 is configured in a case where the detected signal from another base station in the same system in the unlicensed band, the use of unlicensed band coordination with other base stations. It should be noted, here the other base stations with other base station system is the same carrier LTE system.
[0092]
Next, a specific example illustrating a process of coordination with other base station uses unlicensed band is, in this example, based on the detection result of the base station and the unlicensed band of the user equipment to coordinate with other base stations, but the present invention is not limited to here, only the coordinate may be performed based on the detection result of the detection result of the base station or user equipment.
[0093]
When the base station or the user equipment detects an LTE signal with a target frequency band from the same carrier. The base station may be coordinated through, for example, an X2 interface and the other base stations have been accessed. For existing LTE standard, and we have defined a number of inter-cell interference coordination (ICIC) associated X2 message, such as a high interference indication (the HII) and overload indication (OI) message and the like. HII can be seen as a proactive tool ICIC, to avoid low signal to interference noise ratio situation as much as possible. And OI is a passive tool ICIC, substantially in three levels (low, medium, high) indicating the level of interference experienced in a cell on different resource faster. OI to neighboring base stations, for example, can change its scheduling behavior to change the interference situation of the base station sent the OI.
[0094]
In a base station or user equipment detects other carriers occupy the target base station frequency band, the information may indicate MBSFN is determined by detecting the remaining transmission time, for example. Detecting again the base station may wait time corresponding to the target frequency band. Further, if the detected base stations of different operators in the use of a target frequency band and to be waiting time according to the indication information corresponding to the target frequency band after detection.
[0095]
At the base station and the user equipment are detected base stations of different operators are using the target frequency band: If the base station and the user equipment detects that the information from the same base station, the base station would only need to wait for access to the transfer is complete; If the detected information from the base station is not, then there are two different base stations described in the transmission band, the base station can re-select a new target frequency band, or the base station may have to wait for access using the two base stations after transmission is completed the target band.
[0096]
It is understood that the invention is not limited to the details of the above specific examples.
[0097]
One embodiment, the coordination unit 517 may identify the other base station systems based on the same physical cell identity (PCI) signal from the other base station or a synchronization signal (SS) in accordance with. For example, the synchronization signal comprises a primary synchronization signal (PSS) and secondary synchronization signal (SSS), may be used to calculate the PCI.
[0098]
Next, with reference to FIG. 6 illustrates a wireless communication device according to another embodiment.
[0099]
6, a processor 610 and a transceiver apparatus 620 according to wireless communication apparatus 600 of the present embodiment comprises. The processor 610 includes a determination unit 611, generating unit 613, detection unit 615 and a trigger unit 617.

[0100]
The trigger unit 617 is configured to request the user equipment based on the quality and / or unlicensed bands for communication with the user equipment, the trigger detector on the unlicensed band. That is, the wireless communication apparatus according to the present embodiment may be based on detection of a predetermined condition triggering the unlicensed band, the predetermined condition may be a request from a user device, or may employ a licensed band communication quality is lower than a predetermined criterion requiring applicable unlicensed band.
[0101]
For triggered based on a user request is detected, for example, in the case where user discovery transmission rate of the licensed band is below a predetermined level, the user device may request access to the base station unlicensed band. Further, the user equipment may detect unlicensed band, for example, and generates frequency information list transmitted to the base station via a physical uplink control channel (PUCCH). The base station may be provided with a list of user equipment than own list, and selects the base station and the user equipment are detected blank unlicensed band, and band allocation.
[0102]
