实施例3
本实施例提供一种反馈信息的处理方法，作为可选实施例，用于对本申请进行详细和具体的说明，本实施例包括多个具体实施例：
具体实施例一
图8是根据本公开实施例的反馈信息处理方法的流程图一，包括：
步骤1：多个终端(UEs)选择同一个调度时刻(TTI)发送上行传输块(上行链路共享信道PUSCH)，多个UE随机选择资源发送PUSCH信道。 其中终端随机选择的资源包括时频资源以及扩频序列(码资源)。
具体地，资源是终端随机选择的，多个终端选择相同的时频资源甚至选择相同的扩频序列的情况无法避免。
举例来说，在本实施例中一个调度时刻(TTI)仅一个时频资源，多个终端在当前调度时刻选择一个时频资源。对于一个调度时刻多个时频资源的情况，反馈信息生成方式也可以采用本实施例的实现方式，在本实施例不单独说明。在本实施例中多个UE随机选择的扩频序列是冲突的(两个或者多个用户选择相同的扩频序列)。
步骤2：基站(eNB)正确接收多个终端的传输块(PUSCH信道)，判断针对哪些终端生成对应的反馈信息。
具体的，基站在同一个TTI接收到多个终端的上行传输块(PUSCH信道)。基站正确接收到终端的发送的上行传输块后，才能判断该终端在当前TTI有发送PUSCH信道；对于未正确接收的传输块，基站无法判断是哪些终端发送的PUSCH信道。综上所述，基站仅对于正确接收的终端(基站正确解码该终端发送的传输块)生成对应的反馈信息。
步骤3：基站根据正确接收的终端的传输块，生成对应的反馈信息；其中反馈信息包含多个比特信息。
具体地，基站接收到终端的当前TTI的传输块后，需要进行CRC校验。CRC校验通过，表示基站正确接收该传输块。CRC校验通过后，基站侧保存该传输块对应的CRC校验序列。反馈信息为基站侧保存的CRC检验序列。其中不同终端的传输块不同，生成的CRC检验序列也不相同。反馈信息的生成方式，基站和终端已经统一。
举例来说：
终端的MAC层生成传输块(传输块包含的比特为：UE ID(40bits)+有效业务比特(例如0101010101010101))递交给物理层，物理层接收到传输块后添加CRC检验比特，这时传输块包含的比特为UE ID+有效业务比特(0101010101010101)+CRC检验比特。添加CRC后的处理流程，本实施 不一一说明。
基站收到传输块(UE ID+有效业务比特(0101010101010101)+CRC检验比特)，先进行CRC校验，CRC检验通过后表示基站正确接收到终端传输的传输块。
基站侧生成的反馈信息为该传输块(UE ID(40bits)+有效业务比特(例如0101010101010101))生成的CRC校验比特。
步骤4：基站按照既定反馈方式对正确接收的多个终端的传输块下发反馈信息。
反馈方式为基站MAC实体通过一个MAC PDU下发多个用户反馈信息，图9是根据本公开实施例的N个用户的反馈信息的格式示意图，也就是反馈信息的逻辑排列格式。图10是本公开实施例的反馈信息MAC PDU示意图一；图11是本公开实施例的单用户反馈信息构成的协议数据单元示意图，图12是本公开实施例的反馈信息PDU示意图二；图13是本公开实施例的多用户反馈信息构成的PDU示意图，见图9、图10、图11、图12以及图13。
图10中，MAC头(MAC header)由一个或多个MAC子头(MAC subheader)组成。每个子头(subheader)对应一个MAC PDU，或一个MAC CE(Medium Access Control control element)，或padding。其中subheader也由4个域组成：R/R/E/LCID，LCID是Logical Channel ID的简称，用于指示该对应的PDU、MAC CE的类型、或对应的padding；R为保留比特，设置为0；E为扩展比特，指示该子头后是否存在子头。
其中，每个用户的反馈信息可以单独构成一个MAC CE，不同的MAC CE通过级联方式排列；
或者，多个用户的反馈信息构成一个PDU，每个用户占据相应地字节数，不同用户反馈信息采用级联方式。
具体地，基站侧根据正确接收的终端的上行传输块(PUSCH信道)所在的物理上行共享信道PUSCH的时域位置计算出对应的RNTI。基站侧下发 计算所得的RNTI加扰的物理下行控制信道PDCCH指示携带了反馈信息所在的下行传输块(PDSCH信道)。
步骤5：终端解码物理下行控制链路(PDCCH)，根据解码的PDCCH解码对应的PDSCH。终端解码PDSCH，并递交到MAC层，确认MAC CE或者MAC PDU中是否存在自己的反馈信息。终端确认存在自己的反馈信息，流程结束；否则回到步骤1。
通过上述流程，不同的UE可是识别对应的反馈信息，有效的避免了反馈信息的冲突以及反馈信息量大的问题。
具体实施例二
图14是根据本公开实施例的反馈信息处理方法的流程图二，包括：
步骤1：多个终端(UE)选择同一个调度时刻(TTI)发送上行传输块(上行链路共享信道PUSCH)，多个UE随机选择资源发送PUSCH信道。其中终端随机选择的资源包括时频资源以及扩频序列。
具体地，因资源是终端随机选择的，多个终端选择相同的时频资源甚至选择相同的扩频序列的情况都无法避免。
举例来说，在本实施例中一个调度时刻仅一个时频资源，多个终端在当前调度时刻选择一个时频资源。对于一个调度时刻多个时频资源的情况，反馈信息生成方式也可以采用本实施例的实现方式，在本实施例不单独说明。在本实施例中多个UE随机选择的扩频序列是冲突的(两个或者多个用户选择相同的扩频序列)。
步骤2：基站正确接收多个终端的传输块(PUSCH信道)，判断针对哪些终端生成对应的反馈信息
具体的，基站在同一个TTI接收到多个终端的上行传输块(PUSCH信道)。基站正确接收到终端的发送的上行传输块后，才能判断该终端在当前TTI有发送PUSCH信道；对于未正确接收的传输块，基站无法判断是哪些终端发送的PUSCH信道。综上所述，基站仅对于正确接收的终端(基站正确解码该终端发送的传输块)生成对应的反馈信息。
步骤3：基站根据正确接收的终端的传输块，生成对应的反馈信息；其中反馈信息包含多个比特信息
具体地，基站接收到终端的当前TTI的传输块后，需要进行CRC校验。CRC校验通过，表示基站正确接收该传输块。针对正确接收的传输块，提取部分数据信息，数据信息包括UE ID序列或者数据信息中的某些连续的比特，根据UE ID序列或者数据信息中的某些连续的比特生成对应的CRC加扰序列，其中UE ID不同以及数据信息中的某些连续的比特不同，生成的CRC加扰序列也不相同。某些连续比特为不同UE相关性低与一定门限的比特序列，所选择的数据序列UE和基站已经确定好。反馈信息为生成的CRC加扰序列。反馈信息的生成方式，基站和终端已经统一。
举例来说：
终端的MAC层生成传输块(传输块包含的比特为：UE ID(40bits)+有效业务比特(例如0101010101010101))递交给物理层，物理层接收到传输块后添加CRC检验比特，这时传输块包含的比特为UE ID+有效业务比特(0101010101010101)+CRC检验比特。添加CRC后的处理流程，本实施不一一说明。

步骤5：终端解码物理下行控制链路(PDCCH)，根据解码的PDCCH解码对应的PDSCH。终端解码PDSCH，并递交到MAC层，确认MAC CE或者MAC PDU中是否存在自己的反馈信息。终端确认存在自己的反馈信息，流程结束；否则回到步骤1。

举例来说，在本实施例中一个调度时刻仅一个时频资源，多个终端在当前调度时刻选择一个时频资源。对于一个调度时刻多个时频资源的情况，反馈信息生成方式也可以采用本实施例的实现方式，在本实施例不单独说明。在本实施例中多个UE随机选择的扩频序列是冲突的(两个或者多个 用户选择相同的扩频序列)。
