Description

发送反馈信息的方法和设备
本申请要求于2017年03月23日提交中国专利局、申请号为201710179901.5、申请名称为“发送反馈信息的方法和设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信领域，尤其涉及一种发送反馈信息的方法和设备。
背景技术
在无线通信系统中，为了减小编译码的复杂度，一个传输块(transport block，TB)被划分为多个编码块(code block，CB)，每个CB都具有独立的校验功能，此外，每个TB也具有独立的校验功能，当一个TB中的每个CB都校验成功后，接收设备还需要对该TB进行校验，以便于及时发现虚警(即，某些CB解码错误却通过校验的情况)，减小重传的时延。
第五代(5th-Generation，5G)通信系统提出了支持超高可靠性与超低时延(ultra reliable&low latency communication，URLLC)业务的要求，在URLLC场景中，一般要求无线空口的传输时延在1ms以内且达到99.999％的传输可靠性，并且对数据传输的时延提出了苛刻的要求。
为了满足URLLC场景对数据传输的要求，发送设备会优先发送优先级较高的数据，例如，对已经开始传输的TB进行打孔(即，覆盖已经生成的数据)，或者同时发送优先级较高的数据和已经生成的TB，从而这些TB中部分CB或者全部CB极有可能解码失败，发送端需要重传解码失败的CB。
因此，如何确定TB中解码失败的CB以提高重传效率是当前亟需解决的问题。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了一种适用本申请的通信系统100。该通信系统100包括接入网设备110和 终端设备120，接入网设备110与终端设备120通过无线网络进行通信，当终端设备120发送数据时，无线通信模块可对信息进行编码以用于传输，具体地，无线通信模块可获取要通过信道发送至接入网设备110的一定数目的数据比特，这些数据比特例如是处理模块生成的、从其它设备接收的或者在存储模块中保存的数据比特。这些数据比特可包含在一个或多个传输块(也可称为信息块或数据块)中，传输块可被分段以产生多个编码块。
在本申请中，终端设备可称为接入终端、用户设备(user equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G通信系统中的用户设备。
接入网设备可以是码分多址(code division multiple access，CDMA)系统中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(node B，NB)，还可以是长期演进(long term evolution，LTE)系统中的演进型基站(evolutional node B，eNB)，还可以是5G通信系统中的基站(gNB)，上述基站仅是举例说明，接入网设备还可以为中继站、接入点、车载设备、可穿戴设备以及其它类型的设备。
上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，例如，通信系统中包括的接入网设备和终端设备的数量还可以是其它的数量。
为了便于理解本申请，在介绍本申请提供的发送反馈信息的方法前，首先对本申请涉及的概念做简要介绍。
在本申请中，一个TB可以被划分为一个或多个CBG，每个CBG包括至少一个CB。例如，一个TB被划分成的CBG的数量，可以根据该TB的比特数多少来确定，也可以根据该TB所占的时域和/或频域资源的多少来确定，还可以通过高层信令直接配置。
TB中的CB可以按照预定的映射规则映射到时频资源上，例如，该预定的映射规则为：按照CB索引且按照先频域后时域的顺序依次映射；或者该预定的映射规则为：把要映射的频域划分为多个子频域，然后在每个子频域内分别进行映射。
基于上述映射规则，一个TB被划分成CBG的划分方式可以为基于该TB所映射到的时频资源来划分，比如时间维度、频率维度或时频两维划分方式，此种方式下，被划分成的多个CBG中可能会存在相同的某个CB，也可能不存在相同的CB，被划分成的多个CBG中是否存在相同的CB取决于上述最终的资源映射结果；
TB中的CB还可以通过其它规则(比如划分方式与TB映射到的时频资源无关，且与传输块的比特数量有关)或信令通知将CB划分为多个CBG，此种方式下，被划分成的多个CBG中一般不存在相同的CB。
本申请对TB的划分方式不做限定，下面举出两个例子，该两个例子不应理解为对本申请的TB的划分方式的限定。
TB的划分方式1：
第一TB包括4个CB，分别为CB1、CB2、CB3和CB4，可以根据上述其它规则或者高层信令的指示将该第一TB划分为2个CBG，即CBG1和CBG2，其中，CBG1包括CB1和CB2，CBG2包括CB3和CB4；
第一TB包括8个CB，分别为CB1、CB2、CB3、CB4、CB5、CB6、CB7和CB8，可以根据上述映射规则或者高层信令的指示将第一TB划分为2个CBG，即CBG1和CBG2，其中，CBG1包括CB1、CB2、CB3和CB4，CBG2包括CB5、CB6、CB7和CB8；
第一TB包括8个CB，分别为CB1、CB2、CB3、CB4、CB5、CB6、CB7和CB8，可以根据上述映射规则或者高层信令的指示将该第一TB划分为4个CBG，即CBG1、CBG2、CBG3和CBG4，其中，CBG1包括CB1和CB2，CBG2包括CB3和CB4，CBG3包括CB5和CB6，CBG4包括CB7和CB8。
TB的划分方式2：
图2示出了本申请提供的一种TB的划分方式的示意图。如图2所示，第一TB由42个CB组成，按照先频域后时域的顺序映射到12个时域符号上，并按照时域符号的维度将第一TB划分为12个CBG，由于单个时域符号对应的频域资源有限，部分CB未能全部映射至同一个时域符号上，例如，CBG1包括CB1至CB4，CBG2包括CB4至CB7，CB4为CBG1和CBG2的公共CB。
当通信系统中传输的TB划分为多个CBG时，接收端可以根据每个CBG的解码状态向发送端发送反馈信息，当少量CBG解码失败时，发送端仅需重传解码失败的CBG，无需重传整个TB，提高了资源利用率以及数据传输的效率。
发送端根据接收到的反馈信息确定TB传输成功后，可以向接收端发送新的TB。例如，基站可以通过调度信息中的混合自动重传请求(hybrid automatic repeat request，HARQ)进程号字段和新数据指示(new data indicator，NDI)字段指示当前传输的数据是初传还是重传。终端设备先后接收到两个调度信息后，如果该两个调度信息携带的HARQ进程号字段相同，且该两个调度信息携带的NDI字段状态不同，则终端设备可确定后一个调度信息调度的HARQ进程对应的是新数据的传输；如果该两个调度信息携带的HARQ进程号字段相同，且该两个调度信息携带的NDI字段状态相同，则终端设备可确定后一个调度信息调度的HARQ进程对应的是旧数据的重传。当重传的数据是TB的部分CBG时，可以通过在调度信息中加入新的指示字段指示部分重传，也可以通过复用调度信息中现有的字段进行字段的重新解读，例如，重新解读调度信息中的调制编码方式(modulation coding scheme，MCS)字段。上述方法仅是举例说明，本申请不限于此。
接收端接收到发送端发送的CBG后进行解码，其中，解码成功是指接收端获取CBG包括的全部有效信息比特并且校验成功，本申请对CBG的校验方法不做限定，作为一个可选的示例，CBG可以通过循环冗余校验(cyclic redundancy check，CRC)进行校验，或者通过CBG相对应的预设校验矩阵来校验。解码失败是指UE未获取CBG包括的全部有效信息比特，或者UE获取了CBG包括的全部有效信息比特但是该CBG校验失败。
需要指出的是，对于一个TB来说，即使该TB的每一个CBG都解码成功，也不能认为该TB解码成功，因此，在TB包括的每一个CBG都解码成功后，还需要对TB进行校验，当该TB整体校验成功后(比如通过TB CRC进行校验)，才能确定该TB解码成功，。
接收端对接收到的CBG进行解码处理后需要向发送端反馈各个CBG的解码状态，接收端可以通过肯定应答(acknowledge，ACK)反馈CBG解码成功的状态或TB解码成功的状态，接收端还可以通过否定应答(negative acknowledgement，NACK)反馈CBG解码失败或TB解码失败的状态。每个CBG反馈信息可以为一个比特，接收端在一个时间 单元内发送的全部反馈信息(即，反馈信息集合)的码本大小与接收到的CBG的数量相关，但是并不意味着反馈信息集合的码本大小就等于接收到的CBG的数量，反馈信息集合的码本还可以包括TB是否通过校验的信息和/或表征距离该TB可以被正确解码的冗余信息等。
下面，将详细描述本申请提供的发送反馈信息的方法。
图3是本申请提供的一种发送反馈信息的方法的示意性流程图。方法300包括：
S310，第二设备从第一设备接收第一TB，所述第一TB包括多个CBG，所述多个CBG包括所述第二设备在第一时间单元内接收到的第一CBG和第二CBG，所述第一时间单元内接收到的所述第一CBG为解码成功的CBG，所述第一时间单元内接收到的所述第二CBG为未解码成功的CBG。
S320，所述第二设备生成第一反馈信息集合，其中，所述第一反馈信息集合包括第一反馈信息和第二反馈信息，所述第一反馈信息用于反馈所述第一CBG在所述第一时间单元至第二时间单元之间的解码状态，所述第二反馈信息用于反馈所述第二CBG在所述第二时间单元之后的解码状态，所述第二时间单元是所述第二设备在所述第一时间单元之后接收到所述第二CBG的时间单元，所述第二设备在所述第二时间单元内未接收到所述第一CBG。
S330，所述第二设备在第三时间单元内向所述第一设备发送所述第一反馈信息集合。
方法300中，第二设备可以是终端设备，也可以是接入网设备，当第二设备为终端设备时，第一设备为接入网设备，当第一设备为接入网设备时，第二设备为终端设备。为方便理解，以下，以第一设备是基站、第二设备是UE为例对本申请的技术方案进行说明。
第一TB为第一设备向第二设备发送的任意一个TB，第一TB可以按照预定义的规则划分为多个CBG，每个CBG包括至少一个CB。基站向UE发送的第一TB可以在一个时间单元内完成发送，也可以在多个时间单元内完成发送，本申请对此不做限定。相应地，UE在第一时间单元内接收到的第一CBG和第二CBG可以是第一TB包括的全部CBG，也可以是第一TB包括的部分CBG。
应理解，在本申请中，一个时间单元的长度可以任意设定，本申请对此不做限定。
例如，1个时间单元可以包括一个或多个子帧。
或者，1个时间单元可以包括一个或多个时隙(slot)或微时隙(mini-slot)。
或者，1个时间单元可以包括一个或多个时域符号。
或者，1个时间单元可以包括一个或多个传输时间间隔(transmission time interval，TTI)或短传输时间间隔(short transmission time interval，sTTI)。
或者，1个时间单元的长度为1毫秒(ms)。
或者，1个时间单元的长度小于1ms。
此外，本申请对于第一TB的传输方式和传输第一TB使用的资源均不做限定。例如，第一TB可以通过基于调度(grant-based)的方式传输，也可以通过免调度(grant-free)的方式传输，传输第一TB使用的频谱资源可以是授权频谱，也可以是非授权频谱或者其它共享频谱。
当UE在第一时间单元接收到第一TB包括的CBG后，UE对第一TB包括的CBG进行解码，第一CBG为解码成功的CBG，第二CBG为解码失败的CBG。应理解，第一CBG 可以是一个CBG，也可以是多个CBG，第二CBG可以是一个CBG，也可以是多个CBG。
在一个可选的实施例中，所述第一反馈信息用于反馈在所述第一时间单元内接收到的所述第一CBG的解码状态；在又一个可选的实施例中，所述第二反馈信息用于反馈在所述第二时间单元内接收到的所述第二CBG的解码状态。
此外，在URLLC场景中，基站可能无需等待UE的反馈连续传输K次CBG，则第一时间单元应被理解为UE接收到该K次传输所用的时间单元。
例如，当K＝3时，UE在第一时间单元内接收到的CBG为基站三次传输的CBG，则第一CBG可以指UE将基站三次传输的CBG进行合并解码后确定的解码成功的CBG，第二CBG可以指UE将基站三次传输的CBG进行合并解码后确定的解码失败的CBG。
针对第一CBG和第二CBG，UE可以仅反馈一次解码状态，也可以反馈多次解码状态。
基站收到UE针对第一CBG和第二CBG发送的反馈信息后，确定重传第二CBG以及不再重传第一CBG，UE在第二时间单元内接收到第二CBG后对第二CBG进行解码，随后生成第二反馈信息，并在第三时间单元内向基站发送包括该第二反馈信息的第一反馈信息集合。
当UE在第二时间单元内接收到的第二CBG仍然解码失败时，第二反馈信息为NACK，为了保证基站能够识别虚警，即，为了保证基站能够识别该第二反馈信息是指示第二CBG解码失败还是指示第一TB校验失败，UE需要同时指示第一CBG在第一时间单元至第二时间单元之间的解码状态，即，第一反馈信息集合需要同时包括第一反馈信息和第二反馈信息。
在本申请中，第一反馈信息包括两种情况：ACK和NACK。其中，
当第二CBG在第二时间单元至第三时间单元之间解码成功且第一TB在第二时间单元至第三时间单元之间校验成功时，第一CBG在所述第一时间单元至第二时间单元之间的解码状态为解码成功，即，第一反馈信息为ACK；
当第二CBG在第二时间单元至第三时间单元之间解码成功且第一TB在第二时间单元至第三时间单元之间校验失败时，说明第一CBG在第二时间单元之前的解码成功的状态实际是不正确的或者第二CBG在第二时间单元至第三时间单元之间解码成功的状态实际是不正确的或者两者实际都是不正确的，即此时第一CBG和第二CBG中至少一个出现了解码校验虚警，第一CBG在第一时间单元至第二时间单元之间的解码状态应为解码失败，即，第一反馈信息为NACK；
当第二CBG在第二时间单元至第三时间单元之间解码失败时，UE不会对第一TB进行校验或者由于第二CBG的解码失败会导致第一TB的校验基本上是无法通过的，UE暂且认为第一CBG在第一时间单元至第二时间单元之间的解码状态为解码成功，即，第一反馈信息为ACK。
例如，当第一反馈信息为ACK且第二反馈信息为NACK时，基站确定第二CBG解码失败，基站可以在第三时间单元之后仅重传第二CBG，无需重传整个第一TB，从而提高了重传效率。
又例如，当第一反馈信息为ACK且第二反馈信息为ACK时，基站确定第二CBG解码成功且第一TB解码成功。
再例如，当第一反馈信息为NACK且第二反馈信息为NACK时，基站确定第一TB校验失败，基站可以在第三时间单元之后重传第一TB。
应理解，在本申请中，“当…时”、“若”以及“如果”均指在某种客观情况下UE或者基站会做出相应的处理，并非是限定时间，且也不要求UE或基站实现时一定要有该判断的动作，也不意味着存在其它限定。
上述实施例仅是举例说明，本申请不限于此。
例如，当基站未接收到UE在第一时间单元至第二时间单元之间发送的反馈信息时，基站可能会重传第一CBG(简称为“重传第一CBG”)，当UE在第二时间单元前接收到该重传第一CBG时，UE可以直接确定第一CBG的解码状态为ACK，此时，第一反馈信息仍然用于反馈第一CBG在第一时间单元至第二时间单元之间的解码状态。
此外，本申请对UE发送第一反馈信息集合的具体方式不做限定，第一反馈信息集合可以是UE主动发送的，也可以是UE根据基站发送的触发信息(例如，征集信息)发送的。
综上，本申请提供的发送反馈信息的方法，能够使得传输TB的设备识别出虚警与非虚警，从而提高了重传的效率。
可选地，所述第一反馈信息包括至少一个NACK，其中，所述第一反馈信息用于反馈所述第一TB校验失败且所述多个CBG分别校验成功。
例如，第一CBG包括3个CBG。当没有出现虚警时，第一反馈信息为3个ACK；当出现虚警时，第一反馈信息可以为1个NACK和2个ACK。
从而，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述至少一个NACK与所述第一CBG一一对应。
例如，第一CBG包括3个CBG。当没有出现虚警时，第一反馈信息为3个ACK；当出现虚警时，第一反馈信息可以为3个NACK。
从而，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述第一反馈信息包括与所述第一CBG一一对应的ACK，其中，所述第二CBG在所述第二时间单元至所述第三时间单元之间解码失败，或者，所述第二CBG在所述第二时间单元至所述第三时间单元之间解码成功且所述第一TB校验成功。
从而，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述第一反馈信息集合包括与所述多个CBG一一对应的多个ACK，所述第一TB对应第一传输进程，方法300还包括：
S340，所述第二设备从所述第一设备接收征集信息，所述征集信息用于指示所述第二设备上报至少一个传输进程对应的CBG的反馈信息，所述至少一个传输进程包括所述第一传输进程。
S350，所述第二设备在第四时间单元内向所述第一设备发送与所述第一传输进程对应的第二反馈信息集合，其中，所述第二反馈信息集合包括与所述多个CBG一一对应的多个NACK，所述第二设备在所述第三时间单元至所述第四时间单元之间未接收到与所述第一传输进程对应的CBG。
当第一反馈信息集合包括与属于第一TB的多个CBG一一对应的ACK时，说明该多个CBG分别解码成功且第一TB校验成功。随后，基站可以向UE发送新的TB，新TB 对应第一传输进程和/或第二传输进程，第二传输进程与第一传输进程不同。随后，基站向UE征集第一传输进程和第二传输进程的反馈信息。
由于UE可能没有接收到与第一传输进程对应的TB(例如，基站没有调度第一传输进程，或者基站调度了第一传输进程但UE没有接收到调度信息)，因此，当基站向UE发送征集信息征集第一传输进程对应的CBG的反馈信息时，UE会误认为基站征集第一TB的反馈信息，并向基站发送ACK，实际上，UE并未接收到与第一传输进程对应的新TB，从而会导致数据传输错误，引发后续的高层重传，降低了重传效率。
为了避免出现上述情况，UE在发送了不包括NACK的第一反馈信息集合后，当UE接收到征集信息时，如果UE接收到了与第一传输进程对应的CBG，则根据解码状态进行反馈；如果UE没有接收到与第一传输进程对应的CBG，则反馈与第一TB对应的多个CBG一一对应的多个NACK，该多个NACK属于第二反馈信息集合，第二反馈信息集合还可以包括第一传输进程的进程号。
因此，根据本申请提供的发送反馈信息的方法，接收端在未接收到与第一传输进程对应的CBG却收到要求反馈第一传输进程的征集信息时，可以反馈多个NACK，从而避免了数据传输错误，以及避免了接收端由于漏检了第一传输进程的控制信道却上报ACK而导致的物理层数据包的丢失。

S410，第二设备从第一设备接收第一TB，所述第一TB包括多个CBG。
S420，所述第二设备对所述多个CBG分别进行解码。
S430，所述第二设备向所述第一设备发送第三反馈信息集合，其中，所述第三反馈信息集合包括与所述多个CBG一一对应的多个NACK，所述第三反馈信息集合用于指示所述多个CBG校验成功且所述第一TB校验失败。
方法400中，第一设备例如是基站，第二设备例如是UE。
S410中，所述多个CBG可以是UE在一个时间单元内接收到的CBG，也可以是UE在多个时间单元内接收到的CBG，本申请对该多个CBG的传输方式不做限定。该多个CBG解码结果包括以下四种情况。
情况1：该多个CBG分别校验成功且第一TB校验成功，UE发送与该多个CBG一一对应的多个ACK。
情况2：该多个CBG部分校验成功部分校验失败，UE发送相应的ACK和NACK。
情况3：该多个CBG全部校验失败，UE发送一个NACK。
情况4：该多个CBG分别校验成功但是第一TB校验失败(即，虚警)，UE发送与该多个CBG一一对应的多个NACK。
S430中，第三反馈信息集合还可以包括其它信息。此外，第二设备可以自动发送第三信息集合，也可以根据第一设备发送的触发信息发送第三信息集合。
综上，本申请提供的发送反馈信息的方法，能够使得传输TB的设备识别出虚警与非虚警，从而提高了重传的效率。
可选地，方法400还包括：
S440，所述第二设备在第一时间单元内从所述第一设备接收所述多个CBG，其中，所述多个CBG包括第一CBG和第二CBG，所述第一时间单元内接收到的所述第一CBG 为解码成功的CBG，所述第一时间单元内接收到的所述第二CBG为解码失败的CBG。

S470，所述第二设备在第三时间单元内向所述第一设备发送所述第一反馈信息集合。

基站在第五时间单元至第六时间单元之间接收到第一TB的反馈信息，并根据该反馈信息确定第一TB中部分CBG(即，第一CBG)解码成功，部分CBG(即，第二CBG)解码失败。
基站在第六时间单元内向UE发送第二CBG，并且不再发送第一CBG。
随后，基站在第七时间单元内接收到UE发送的第一反馈信息集合，该第一反馈信息集合包括第一反馈信息以及第二反馈信息，方法500中的第一反馈信息集合可以与方法300中的第一反馈信息集合相同，方法500中的基站也可以与方法300中的基站相同，为了简洁，在次不再赘述。

基站征集反馈信息时可能会征集全部传输进程的反馈信息，由于基站没有调度第一传输进程，因此，基站会接收到与第一传输进程对应的多个NACK，且该多个NACK与第一TB所包括的多个CBG是一一对应的。具体过程可参考S330和S340对应的实施例，在此不再赘述。

根据本申请提供的发送反馈信息的方法，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述第一反馈信息包括至少一个NACK，其中，所述第一反馈信息用于反馈所述第一TB校验失败且所述多个CBG分别校验成功。
从而，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述至少一个NACK与所述第一CBG一一对应。
从而，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述第一反馈信息包括与所述第一CBG一一对应的ACK，其中，所述第二CBG在所述第二时间单元至所述第三时间单元之间解码失败，或者，所述第二CBG在所述第二时间单元至所述第三时间单元之间解码成功且所述第一TB校验成功。
从而，传输TB的设备可以识别出虚警和非虚警，能够提高重传的效率。
可选地，所述第一反馈信息集合包括与所述多个CBG一一对应的多个ACK，所述第一TB对应第一传输进程，方法600还包括：
S670，所述第一设备向所述第二设备发送第二TB，所述第二TB包括至少一个CBG，所述第二TB对应第二传输进程。

当第一反馈信息集合包括与属于第一TB的多个CBG一一对应的ACK时，说明该多个CBG分别解码成功且第一TB校验成功。随后，基站可以向UE发送新的TB，新TB例如为第二TB，第二TB对应第二传输进程，第二传输进程与第一传输进程不同。随后，基站向UE征集反馈信息。
基站征集反馈信息时可能会征集全部传输进程的反馈信息，由于基站没有调度第一传输进程，因此，基站会接收到与第一传输进程对应的多个NACK，且该多个NACK与第一TB所包括的多个CBG是一一对应的。具体过程可参考S330和S340对应的实施例，在此不再赘述。
因此，根据本申请提供的接收反馈信息的方法，接收端在未接收到与第一传输进程对应的CBG却收到要求反馈第一传输进程的征集信息时，可以反馈多个NACK，从而避免了数据传输错误，以及避免了接收端由于漏检了第一传输进程的控制信道却上报ACK而导致的物理层数据包的丢失。
