HARQ上行反馈信息的处理方法和装置  Method and device for processing HARQ uplink feedback information
技术领域 本发明属于移动通信领域， 尤其涉及一种混合自动重传请求 （Hybrid Automatic Repeat request, HARQ )上行反馈信息的处理方法和装置。 The present invention relates to the field of mobile communications, and in particular, to a method and apparatus for processing hybrid feedback information of Hybrid Automatic Repeat Request (HARQ).
背景技术 中继（Relay )技术作为一种新兴的技术， 引起了越来越广泛的关注， 被 视为 B3G/4G的关键技术。由于未来无线通信或蜂窝系统要求完善网络覆盖， 支持更高速率传输， 这对无线通信技术提出了新的挑战。 同时， 系统建造和 维护的费用问题更加突出。 随着传输速率及通信距离的增加， 电池的耗能问 题也变得突出， 而且未来的无线通信将会釆用更高频率， 由此造成的路径损 耗衰减更加严重。通过中继技术，可以将传统的单跳链路分成多个多跳链路， 由于距离缩短， 这将极大地减小路径损耗， 有助于提高传输质量， 扩大通信 范围， 从而为用户提供更快速更优质的服务。 在引入中继节点 （Relay Node, RN )的网络中， 如图 1所示， 网络中基 站（ Evolved NodeB, eNB ) 与宏小区用户（Macro User Equipment, M-UE)间 的链路称为直传链路（Direct Link ) , 基站与中继节点间的链路称为回程链 路 ( Backhaul Link ) , 中继节点与中继域用户终端 (Relay User Equipment, R-UE)间的链路称为接入链路（ Access Link ) 。 在 LTE系统中， eNB与 UE之间对于信号的传输需要建立 HARQ过程 并进行相应的反馈。 当 UE接收到 eNB的信号后， 根据信号的接收解码情况 生成对此 HARQ 进程的上行反馈信息， 如接收正确即生成确认 ( Acknowledgement, ACK )反馈信息， 接收不正确即生成非确认（Negative Acknowledgement , NACK )反馈信息，并将 ACK/NACK信息上行发送给 eNB。 eNB根据接收到的反馈信息进行下一步处理，如果收到 ACK,则继续传输新 的数据， 若收到 NACK, 则将接收失败的数据重新传输给 UE。 在长期演进（ Long Term Evolution, LTE )系统的直传链路上， ACK/NACK 上行反馈信息承载在物理上行控制信道（Physical Uplink Control Channel, PUCCH )上， 分为 PUCCH格式（format ) la/lb, 如图 2和图 3所示。 当系统帧结构釆用普通循环前缀（ Normal Cyclic Prefix, Normal CP )时， 每个子帧含有 14 个单载波频分多址 ( Single Carrier-Frequency Division Multiple Access, SC-FDMA )符号， 如图 2所示， 分为 2个时隙（slot ) , 每 个 slot上包括 7个 SC-FDMA符号，在 slot间进行跳频（ Hopping )。 图 2 ( a ) 为普通结构，其中 #0、 #1、 #5 , #6、 #7、 #8、 #12和 #13符号上承载 ACK/NACK 信息，剩余的 #2、#3、#4、#9、#10和 #11符号上映射导频信号（Reference Signal, RS ) , 图 2 ( b )为同时承载测量参考信号（ Sounding Reference Signal, SRS ) 的截短（Shortened ) 结构， 其中 #0、 #1、 #5 , #6、 #7、 #8和 #12符号上承载 ACK/NACK信息， #13符号承载 SRS , 剩余的 #2、 #3、 #4、 #9、 #10和 #11 符号上映射导频信号。 当系统帧结构釆用扩展循环前缀（ Extended Cyclic Prefix, Extended CP ) 时，每子帧含有 12个 SC-FDMA符号，如图 3所示，分为 2个 slot,每个 slot 上包括 6个 SC-FDMA符号， 在 slot间进行跳频 （Hopping ) , 图 3 ( a )为 普通结构，其中的 #0、 #1、 #4, #5、 #6、 #7、 #10和 #11符号上承载 ACK/NACK 信息， 剩余的 #2、 #3、 #8和 #9符号上映射 RS信号， 图 3 ( b )为 Shortened 结构， 其中 #0、 #1、 #4 , #5、 #6、 #7和 #10符号上承载 ACK/NACK信息， #11符号承载 SRS, 剩余的 #2、 #3、 #8和 #9符号上映射导频。 在 Direct Link上 , M-UE对生成的 ACK/NACK信息根据系统配置进行 频域扩展和时域扩展等处理后， 映射在所分配的 PUCCH物理资源上。 另外 在相应符号位置映射 RS, 发送给 eNB。 同时， eNB可以分配相同的 PUCCH 物理资源给多个 UE, 由于各个 UE使用的频域扩展索引 CS— index和时域扩 展索引 OC— index具有正交性， 在相同的 PUCCH物理资源上可以复用多个 UE的 ACK/NACK反馈信息，相关参数及资源分配由 eNB配置指示 UE。eNB 在一个子帧内向调度服务的 UE传输一个数据包， 并配置指示与 HARQ反馈 相关的信息， 即 ACK/NACK信息处理相关的参数及资源配置， UE接收数据 后生成 ACK/NACK信息，并根据配置指示对自身的 ACK/NACK信息进行处 理， 上行发射给 eNB。 M-UE根据 eNB的配置指示及相应的计算方式对生成的 ACK/NACK信 息进行处理， 步骤如下： 步骤 10, 获取参数配置指示 BACKGROUND OF THE INVENTION Relay technology, as an emerging technology, has attracted more and more attention and is regarded as a key technology of B3G/4G. Since future wireless communication or cellular systems require complete network coverage and support for higher rate transmission, this poses new challenges for wireless communication technologies. At the same time, the cost of system construction and maintenance is more prominent. As the transmission rate and communication distance increase, the problem of battery energy consumption becomes prominent, and future wireless communication will use higher frequencies, resulting in more serious path loss attenuation. Through the relay technology, the traditional single-hop link can be divided into multiple multi-hop links. This will greatly reduce the path loss due to the shortened distance, which will improve the transmission quality and expand the communication range, thus providing users with more Fast and better service. In the network where the relay node (RN) is introduced, as shown in FIG. 1, the link between the Evolved NodeB (eNB) and the Macro User Equipment (M-UE) in the network is called straight. The link between the base station and the relay node is called a backhaul link, and the link between the relay node and the relay user equipment (R-UE) is called a link. For the access link (Access Link). In the LTE system, the transmission of signals between the eNB and the UE needs to establish a HARQ process and perform corresponding feedback. After receiving the signal of the eNB, the UE generates uplink feedback information for the HARQ process according to the received decoding condition of the signal, and generates Acknowledgement (ACK) feedback information if the receiving is correct, and generates a non-acknowledgment if the receiving is incorrect (Negative Acknowledgement, NACK) feedback information and uplink ACK/NACK information is sent to the eNB. The eNB performs next processing according to the received feedback information. If an ACK is received, the eNB continues to transmit new data. If a NACK is received, the eNB fails to retransmit the received data to the UE. ACK/NACK on the direct link of the Long Term Evolution (LTE) system The uplink feedback information is carried on the Physical Uplink Control Channel (PUCCH) and is divided into PUCCH format (la), as shown in FIG. 2 and FIG. When the system frame structure uses Normal Cyclic Prefix (Normal CP), each subframe contains 14 Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols, as shown in Figure 2. The display is divided into 2 slots, each slot includes 7 SC-FDMA symbols, and hopping is performed between the slots. Figure 2 (a) is a common structure in which #0, #1, #5, #6, #7, #8, #12, and #13 symbols carry ACK/NACK information, and the remaining #2, #3, # 4. The reference signal (RS) is mapped on the #9, #10, and #11 symbols, and FIG. 2(b) is a shortened structure that simultaneously carries a Sounding Reference Signal (SRS), where #0, #1, #5, #6, #7, #8, and #12 symbols carry ACK/NACK information, #13 symbol carries SRS, and the remaining #2, #3, #4, #9, #10 The pilot signal is mapped on the #11 symbol. When the system frame structure uses Extended Cyclic Prefix (Extended CP), each subframe contains 12 SC-FDMA symbols. As shown in Figure 3, it is divided into 2 slots, and each slot includes 6 SCs. -FDMA symbol, frequency hopping (Hopping) between slots, Figure 3 (a) is a common structure, where #0, #1, #4, #5, #6, #7, #10 and #11 symbols The ACK/NACK information is carried, and the remaining #2, #3, #8, and #9 symbols are mapped to the RS signal, and FIG. 3(b) is a Shortened structure, where #0, #1, #4, #5, #6, The #7 and #10 symbols carry ACK/NACK information, the #11 symbol carries SRS, and the remaining #2, #3, #8, and #9 symbols map pilots. On the Direct Link, the M-UE maps the generated ACK/NACK information to the allocated PUCCH physical resources after performing frequency domain extension and time domain extension according to the system configuration. In addition, the RS is mapped at the corresponding symbol position and sent to the eNB. At the same time, the eNB can allocate the same PUCCH physical resource to multiple UEs. The frequency domain extended index CS_index and the time domain extended index OC_index used by each UE have orthogonality and can be reused on the same PUCCH physical resource. The ACK/NACK feedback information of multiple UEs, related parameters and resource allocation are indicated by the eNB to indicate the UE. The eNB transmits a data packet to the UE that schedules the service in one subframe, and configures information indicating the HARQ feedback, that is, the ACK/NACK information processing related parameters and resource configuration, and the UE generates the ACK/NACK information after receiving the data, and according to the eNB, The configuration indication processes the ACK/NACK information of itself and transmits the uplink to the eNB. The M-UE processes the generated ACK/NACK information according to the configuration indication of the eNB and the corresponding calculation manner, and the steps are as follows: Step 10: Acquire a parameter configuration indication

3d) 映射 M-UE将时域扩展后的 z(0序列按照先频域后时域的顺序依次填充到所 分配的 RB对上， 最终完成 ACK/NACK信息向物理资源的映射。 在 Backhaul Link上， HARQ反馈信息与 Direct Link有所不同， eNB下 行发送给 RN的数据包括传输给 RN本身的数据， 以及需 RN中继给 R-UE 个子帧内传输多个数据包、 以及聚合数据包传输等， 使 Backhaul Link 的 HARQ反馈信息与 Direct Link的反馈信息内容可能不同， 可能需要在一个 Backhaul Link上行子帧中上报多顶 ACK/NACK反馈信息。 另一方面， 由于 RN在信号中继转发的收发转换之间需要一定的转换时间间隔， RN在配置的 Backhaul Link上行子帧上， 可实际用于上行传输的 SC-FDMA符号数小于一 个子帧所包含的符号数， 即在 Normal CP时可用符号数小于 14, Extended CP 时可用符号数小于 12, 因此 Backhaul Link的物理上行控制信道（R-PUCCH ) 的信道结构与 Direct Link的 PUCCH也有所不同。 上述信息内容与物理上行 控制信道结构的不同， 使 Backhaul Link的 ACK/NACK上行反馈信息的处理 无法依照 Direct Link方法进行。 3d) mapping The M-UE fills the time-domain extended z (the 0 sequence is sequentially padded to the allocated RB pair in the order of the pre-frequency domain and the time domain, and finally completes mapping of the ACK/NACK information to the physical resource. On the Backhaul Link, the HARQ The feedback information is different from that of the Direct Link. The data that the eNB sends to the RN in the downlink includes the data transmitted to the RN itself, and the RN relays the R-UE sub-frames to transmit multiple data packets, and the aggregated data packet transmission. The HARQ feedback information of the Backhaul Link may be different from the feedback information of the Direct Link. It may be necessary to report multiple ACK/NACK feedback information in a Backhaul Link uplink subframe. On the other hand, the RN performs the transmission and reception conversion of the signal relay. The number of SC-FDMA symbols that can be actually used for uplink transmission is less than the number of symbols included in one subframe, that is, the number of symbols available in Normal CP is less than the number of symbols in the configured Backhaul Link uplink subframe. 14. The number of available symbols in the Extended CP is less than 12, so the channel structure of the Physical Uplink Control Channel (R-PUCCH) of the Backhaul Link is different from that of the Direct Link. Said different information content and structure of the physical uplink control channel, so Backhaul Link ACK / NACK of uplink feedback information can not be treated in accordance with the method of Direct Link.
发明内容 本发明提出了一种 HARQ 上行反馈信息的处理方法和装置， 有效实现 RN将 ACK/NACK上行反馈信息承载于回程链路的 PUCCH上传输给 eNB, 并充分利用 Backhaul link信道条件，提高 Backhaul Link上行反馈信息的传输 效率。 为了解决上述问题， 本发明提供了一种混合自动重传请求 （HARQ )上 行反馈信息的处理方法， 用于回程链路， 该方法包括： 对接收到的数据生成一项反馈信息， 编码得到反馈信息序列； 或者， 对 接收到的多项数据生成多项反馈信息， 编码得到多项反馈信息序列， 对所述 多项反馈信息序列进行复用得到复用后的反馈信息序列； 对所述反馈信息序列或复用后的反馈信息序列进行调制， 得到调制后的 反馈信息序列； SUMMARY OF THE INVENTION The present invention provides a method and a device for processing HARQ uplink feedback information, which effectively implements an RN to transmit ACK/NACK uplink feedback information on a PUCCH of a backhaul link to an eNB, and fully utilizes Backhaul link channel conditions to improve Backhaul.
