信息反馈及接收方法和设备 And a feedback receiving method and apparatus

技术领域 FIELD

[0001] 本发明涉及无线通信领域,尤其涉及一种信息反馈及接收方法和设备。 [0001] The present invention relates to the field of wireless communications, and more particularly to a feedback information receiving method and apparatus. 背景技术 Background technique

[0002] 在长期演进(Long Term Evolution, LTE)及以前的无线通信系统中,一个小区中只有一个载波,在LTE系统中最大带宽为20MHz,如图1所示: [0002] In the LTE (Long Term Evolution, LTE), and before a wireless communication system, a cell is only one carrier in the LTE system maximum bandwidth of 20MHz, shown in Figure 1:

[0003] 在长期演进升级(LTE Advanced, LTE-A)系统中,系统的峰值速率比LTE系统有巨大的提高,要求达到下行mbps,上行500Mbps。 [0003] In Long Term Evolution (LTE Advanced, LTE-A) system, the peak rate of the system has a huge improvement over the LTE system, required to achieve Mbps downlink, uplink 500Mbps. 如果只使用一个最大带宽为20MHz的载波是无法达到峰值速率要求的。 If only a maximum bandwidth of 20MHz carrier is not required to reach peak rate. 因此,LTE-A系统需要扩展终端(UE)可以使用的带宽,由此引入了载波聚合(Carrier Aggregation,CA)技术,即将同一个基站(eNB)下的多个连续或不连续的载波聚合在一起,同时为UE服务,以提供所需的速率。 Therefore, LTE-A system requires a terminal that can be used to expand the bandwidth (the UE), thereby introducing the carrier aggregation (Carrier Aggregation, CA) technology, a plurality of base stations is about the same at (eNB) continuous or discontinuous carrier aggregation together, at the same time serving the UE to provide the desired rate. 这些聚合在一起的载波又称为成员载波(component carrier,CC)。 These carriers, also known as polymerized together carrier (component carrier, CC). 每个小区都可以是一个成员载波,不同eNB下的小区(成员载波)不能聚合。 Each cell may be a carrier, a cell (carrier) at different eNB can not be aggregated. 为了保证LTE系统的UE能在每一个聚合的载波下工作,每一个载波最大不超过20MHz。 In order to ensure UE LTE system capable of operating at each of aggregated carriers, each carrier does not exceed the maximum 20MHz. LTE-A的CA技术如图2所示。 CA technology the LTE-A as shown in FIG.

[0004] 图2所示的LTE-A系统的基站下有4个可以聚合的载波,基站可以同时在4个载波上与UE进行数据传输,以提高系统吞吐量。 [0004] The base station has the LTE-A system shown in FIG. 2 four carriers can be aggregated, the base station may simultaneously with the UE for data transmission on the four carriers, in order to improve system throughput.

[0005] LTE-A版本10 (Rel-IO)中最多支持2个成员载波进行聚合,而LTE-A版本Il(Rel-Il)中将支持最多5个成员载波进行聚合。 In [0005] LTE-A version 10 (Rel-IO) supports up to two carriers polymerization, while in the LTE-A version Il (Rel-Il) supports up to five carriers polymerization.

[0006] 肯定应答/否定应答(ACK/NACK)信息反馈方案如下: [0006] acknowledgment / negative acknowledgment (ACK / NACK) feedback scheme is as follows:

[0007] 对于频分双工(FDD)系统,UE在子帧n_4中接收下行数据,在上行子帧η中反馈该下行子帧上的数据是否需要重传的信令,即ACK/NACK信息。 [0007] For a frequency division duplex (FDD) system, the UE in subframe n_4 receives downlink data, if the uplink subframe η feedback in the downlink sub-frame of data to be retransmitted signaling, i.e. ACK / NACK information . 载波聚合时,子帧η-4中多个下行载波对应的ACK/NACK信息将同时在上行子帧η中反馈。 Carrier aggregation, subframe η-4 ACK / NACK information corresponding to multiple downlink carriers simultaneously feedback in the uplink sub-frame [eta].

[0008] 对于时分双工(TDD)系统,UE可能在同一个上行子帧反馈多个下行子帧所对应的ACK/NACK信息,即UE在下行子帧nk中接收下行数据,在上行子帧η中反馈对应的ACK/ NACK信息,ke K,集合K的取值与系统的上下行配置及具体的子帧编号有关,如表1所示。 [0008] For time division duplex (TDD) system, the frame could UE transmitting ACK / NACK information corresponding to a plurality of downlink subframes with an uplink subframe in which the UE receives downlink data in a downlink subframe nk, the uplink sub-frame ACK / NACK feedback information corresponding to η, KE K, uplink and downlink set value K of the system and the specific configuration of the relevant sub-frame number, as shown in table 1.

[0009] [0009]

Figure CN102394725AD00071

[0010] 表1 [0010] TABLE 1

[0011] 表1中,多个无线帧顺序排列,即若无线帧a中最后一个子帧为k,则无线帧a+Ι中第一个子帧为k+Ι,表2只以一个无线帧为例给出了每个上行子帧所对于的K的情况,其中nk < 0则表示前一无线帧中的下行子帧。 [0011] In Table 1, arranged in a plurality of radio frames sequentially, i.e., when the last radio frame a subframe k, the radio frame a + Ι first subframe is k + Ι, to a wireless Table 2 Example given of the case frame of K for each of the uplink subframe, where nk <0 indicates a radio frame before a downlink subframe.

[0012] ACK/NACK信息可使用物理上行控制信道(PUCCH)传输,且存在多种反馈方式,不同的反馈方式所使用的PUCCH格式也不同,具体包括:基于PUCCH格式la/lb的传输方式、 基于PUCCH格式Ib的信道选择的传输方式、基于PUCCH格式3的复用传输方式。 [0012] ACK / NACK information using a physical uplink control channel (PUCCH) transmission, and plural feedback schemes exist, PUCCH format different feedback method used is also different, comprises: transmission based on the PUCCH format la / lb, and transmission channel based on the PUCCH format Ib is selected, based on PUCCH format multiplexed transmission 3.

[0013] 其中,PUCCH格式la/lb能够承载1或2比特信息;基于PUCCH格式Ib的信道选择最多可承载4比特信息;PUCCH格式3能够承载的信息数量较多,最多可承载48个编码比特。 [0013] wherein, PUCCH format la / lb can carry 1 or 2 bit information; based on channel PUCCH format Ib selection up to carry 4-bit information; larger number information PUCCH format 3 can carry up to carry 48 coded bits . 使用PUCCH格式3传输ACK/NACK信息时,具体所使用的PUCCH由基站通过信令通知UE。 Transmitted using PUCCH format 3 ACK / NACK information when the specific PUCCH used by the base station notifies the UE through signaling.

[0014] 信道状态信息(Channle State Information, CSI)反馈的方案如下: [0014] channel status information signal (Channle State Information, CSI) feedback scheme is as follows:

[0015] LTE系统中,UE需要向基站反馈CSI。 [0015] LTE system, UE needs to feed back CSI to the base station. 基站利用UE反馈的CSI,进行下行动态调度。 The base station uses the UE feeds back the CSI, the downlink dynamic scheduling.

[0016] 根据触发机制的不同,CSI分为两类:周期CSI和非周期CSI。 [0016] Depending on the trigger mechanism, CSI divided into two categories: periodic and aperiodic CSI CSI. 周期CSI的上报周期及周期内的偏移由基站通过无线资源控制(RRC)信令半静态配置,UE根据配置信息在特定的上行子帧中传输CSI。 CSI reporting cycle and offset within the cycle period by the base station through radio resource control (RRC) signaling semi-statically configured, UE transmitting CSI In certain uplink sub-frame according to the configuration information. 在无上行数据传输的子帧中,使用PUCCH上报周期CSI。 In the subframe is no uplink data transmission, using PUCCH reporting period CSI.

[0017] LTE-A Rel-IO的载波聚合系统中,不同成员载波的周期CSI的参数独立配置,UE 在每个上报子帧内只反馈一个成员载波的周期CSI,若多个成员载波的周期CSI发生碰撞, 则按照预定的优先级,反馈对应优先级最高的周期CSI。 [0017] LTE-A Rel-IO polymeric carrier system, different carrier members independent of the periodic CSI configuration parameters, the UE feeds back only one component carrier in each sub-frame period CSI reporting, the period when the plurality of component carriers CSI collision, according to the predetermined priority, the highest priority corresponding to the feedback CSI period.

[0018] 非周期CSI由基站通过下行调度信令触发,UE只有在收到触发信令后才进行CSI 上报,且使用物理上行共享信道(PUSCH)传输非周期CSI。 [0018] CSI aperiodic downlink scheduling signaling is triggered by the base station, the UE only for CSI is reported after receiving the trigger signaling and a physical uplink shared channel (PUSCH) transmission of aperiodic CSI. UE根据基站的触发情况,可同时上报多个成员载波的非周期CSI。 The UE triggers the base station can also reported CSI aperiodic plurality of component carriers.

[0019] ACK/NACK信息与周期CSI同时反馈的方案如下: [0019] ACK / NACK feedback information of the same time period CSI scheme is as follows:

[0020] LTE系统中,基站通过高层信令方式配置UE是否支持使用PUCCH同时传输ACK/ NACK信息和CSI的能力,对于不能同时传输ACK/NACK信息和CSI的终端,当两个信令发送碰撞时,CSI将被丢弃。 [0020] LTE system, the base station through higher layer signaling protocol on the PUCCH whether the UE supports simultaneous transmission of ACK / NACK information and CSI ability to not simultaneously transmit ACK / NACK information and the CSI terminal, signaling collision when two when, CSI is discarded.

[0021] 在LTE-A Rel-IO的载波聚合系统中,即便基站配置UE可以同时传输ACK/NACK信息和CSI,当UE在多个成员载波上接收到下行数据时,若对应的上行子帧中无PUSCH,则CSI 也将被丢弃。 [0021] In the LTE-A Rel-IO carrier aggregation system, even if the base station configures the UE can transmit ACK / NACK information and the CSI, when the UE receives downlink data on multiple carriers if the corresponding uplink subframe no PUSCH, the CSI will also be discarded. 即UE只在主载波上收到下行数据,且配置可以同时传输ACK/NACK信息和CSI 时,才能够将ACK/NACK信息和CSI在PUCCH中同时反馈给基站。 I.e. UE receives downlink data only on the primary carrier, and may be transmitted simultaneously configuration information and the CSI, it is possible to ACK / NACK information and CSI to the base station simultaneously in a PUCCH ACK / NACK.

[0022] PUCCH功率控制的方案如下: [0022] PUCCH power control scheme is as follows:

[0023] LTE系统中,子帧i中PUCCH的UE传输功率Ppura的设置定义如下: [0023] LTE system, provided in the definition of PUCCH in the subframe i Ppura UE transmission power is as follows:

[0094] 步骤31中,终端可以采用级联方式或交织聚合方式,将B比特的编码信息与待反馈的C比特的CSI进行聚合,得到D比特的聚合信息。 In [0094] Step 31, the terminal may interleave the polymerization or in cascade manner, the encoded information bits B and C bits of CSI to be fed back to the polymerization, the polymerization to obtain information D bits.

[0095] 具体的,在采用级联方式时,终端按照系统预定义的或基站通过信令指示的级联顺序,将B比特的编码信息与待反馈的C比特的CSI进行级联,得到D比特的聚合信息; [0095] Specifically, when the cascade mode, the terminal system according to a predefined order cascade or signaling by the base station indicated by the coded information bits B C bits cascaded with CSI to be fed back to give D aggregated information bits;

[0096] 举例说明,在级联顺序为接收应答信息在前、CSI在后时,将B比特的编码信息与C 比特的CSI进行级联的示例如图5A所示。 [0096] way of example, in order to receive the response information cascade front, when the CSI after, the example cascade coding information bits CSI B and C bits is shown in Figure 5A.

[0101] 上述将D比特的聚合信息划分为多组,其具体实现方式可以有多种,其中一种方式是,对于A比特的接收应答信息中的每一个信息比特,将该信息比特对应在B比特的编码信息中的所有编码比特分在同一组内。 [0101] The polymerization of the D-bits of information are divided into a plurality of groups, which can be many specific implementation, one way is for receiving the response of the A-bit of each information bit information, the information bits corresponding to the All the coded bits encoded information bits in the sub-B in the same group. 比如,A比特的接收应答信息为&1,32,33,34,在采用重复编码方式时,B比特的编码信息为a1; a2,a3,a4,B1, a2,a3,a4,B1, ει2,则将B比特的编码信息与C比特的CSI进行聚合后的聚合信息进行分组后,χ相同的\在同一分组内,χ在1 到4之间取值。 For example, A receives the response information bit is & 1,32,33,34, when using repetition coding mode the encoded information bits B is a1; a2, a3, a4, B1, a2, a3, a4, B1, ει2, after the polymerization the information bits will be encoded B and C bits of information for CSI polymerization group, the same [chi] \ in the same group, [chi] values ​​between 1-4.

[0102] 当然,将D比特的聚合信息划分为多组的方式并不局限于上述方式,还可以采用奇偶分组方式,将奇数位上的信息比特分在一组内,将偶数位上的信息比特分在另一组内; 或者采用等分分组方式,将前半部分的信息比特分在一组内,将剩余部分的信息比特分在 [0102] Of course, the aggregated information is divided into groups D of bits is not limited to the manner described above, may also be employed parity packets embodiment, the information bits on the odd bit in a sub-group, the information on the even bit in another set of points within a bit; or with aliquots grouping, the first half of the information bits in a set of points, the rest of the message bits divided in
