Definitions

  • the present disclosure relates to the field of communication technology, and in particular to a HARQ mechanism processing method, indication method, terminal and network side equipment.
  • the Hybrid Automatic Repeat reQuest (HARQ) mechanism is widely used in mobile communication networks.
  • the HARQ mechanism can improve the system’s spectrum efficiency by combining the receiving end to improve the link performance.
  • multiple parallel HARQ processes make the A HARQ round-trip time (Round-Trip Time, RTT) can be used for data transmission through other HARQ processes, thereby increasing the transmission rate.
  • the cell radius is relatively small, and the transmission delay is not large.
  • RTT mainly depends on the duration of the physical channel and the processing time of the receiving and sending end.
  • An important difference between the satellite communication system and the terrestrial cellular system is that the satellite communication system The distance between the terminal and the network is very long, and the transmission delay is very large, which has become the main factor affecting RTT. Therefore, the number of HARQ processes in the satellite communication system is much more than that in the ground cellular system, for example, tens to hundreds of processes.
  • a direct problem caused by a large number of HARQ processes is that the buffer size at the receiving end increases linearly.
  • Deactivating HARQ means that the HARQ mechanism is not used in the physical layer, including that the receiving end does not perform HARQ-ACK feedback on the data packet, the transmitting end does not perform HARQ retransmission of the data packet, and the receiving end does not perform HARQ combining accordingly.
  • HARQ deactivation can be semi-static or dynamic. For the semi-static mode, the terminal does not use HARQ for all data packets within a period of time.

技术领域
本公开涉及通信技术领域，尤其是指一种HARQ机制的处理方法、指示方法、终端及网络侧设备。
背景技术
混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)机制广泛应用于移动通信网络，采用HARQ机制可以通过接收端合并提升链路性能从而提高***的频谱效率，此外，多个并行的HARQ进程使得在一个HARQ进行的往返时间(Round-Trip Time，RTT)内可以通过其他的HARQ进程进行数据传输从而提升了传输速率。
对于地面蜂窝***，小区半径相对较小，传输时延不大，RTT主要取决于物理信道的持续时间以及收发端的处理时间，而卫星通信***相对于地面蜂窝***的一个重要区别在于卫星通信***中终端和网络间的距离很远，传输时延非常大，成为了影响RTT的主要因素。因此，卫星通信***中的HARQ进程数相对地面蜂窝***多得多，例如几十到几百个进程。大量的HARQ进程带来的一个直接问题是接收端的缓存大小线性增加。
为了应对卫星通信***中HARQ进程数过多的问题，一种解决方案是去激活HARQ。去激活HARQ是指在物理层不采用HARQ机制，包括接收端不对数据包进行HARQ-ACK反馈，发送端也不对数据包进行HARQ重传，相应地接收端也不进行HARQ合并。去激活HARQ可以是半静态或者动态的。对于半静态的方式，终端在一段时间内对于所有的数据包都不采用HARQ。对于动态去激活HARQ的方式，发送端则可以对每一个数据包动态得选择是否采用HARQ机制。相对于半静态去激活HARQ机制的方式，动态去激活 HARQ机制的方式更加灵活。但是目前关于如何动态去激活HARQ机制还在研究中，尚无明确的方案。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开实施例提供一种混合自动重传请求HARQ机制的处理方法，应用于终端，包括：
步骤11，接收调度信息，所述调度信息用于调度数据包的传输；
步骤12，根据所述调度信息，确定所述调度信息调度的数据包是否采用HARQ机制。
可选的，调度信息可以为下行控制信息DCI、旁链路控制信息SCI等，在此不做具体限定。
在所述调度信息调度的数据包不采用HARQ机制的情况下，接收所述数据包的接收端不对所述数据包进行HARQ反馈(HARQ-ACK或HARQ-NACK)；发送端也不对该数据包进行HARQ重传。
在所述调度信息调度的数据包采用HARQ机制的情况下，接收端反馈该数据包对应的HARQ反馈(HARQ-ACK或HARQ-NACK)，发送端可以对该数据包进行HARQ重传。
作为一个可选实施例，所述调度信息包括第一比特域，所述第一比特域用于指示激活HARQ或者去激活HARQ；
相应的，步骤12包括：
在所述第一比特域指示激活HARQ的情况下，确定所述调度信息调度的数据包采用HARQ机制；
在所述第一比特域指示去激活HARQ的情况下，确定所述调度信息调度的数据包不采用HARQ机制。
例如，在调度信息中使用一个比特域(即第一比特域)指示是否去激活HARQ。例如，DCI中使用1比特，其两种取值(‘0’和‘1’)分别表示激活HARQ和去激活HARQ。接收端根据该比特域的取值确定是否激活HARQ。若DCI指示去激活HARQ，则不采用HARQ机制，接收端不反馈该数据包对应的HARQ-ACK，并且不缓存该数据包；反之若DCI指示激活HARQ，则采用HARQ机制，接收端反馈该数据包对应的HARQ-ACK，并且如果解码 失败则缓存该数据包到调度信息指示的HARQ进程对应的缓存中，用于后续重传的合并。
进一步，较优地，当DCI指示去激活HARQ时，DCI中与HARQ相关的信息域，例如HARQ进程号、冗余版本信息、新数据指示和/或反馈信道的指示等信息域可以重新定义用于其它的用途。
作为另一个可选实施例，所述调度信息包括第二比特域，所述第二比特域用于指示HARQ进程号；
相应的，步骤12包括：
在所述第二比特域的取值为预先设置的指示去激活HARQ的目标值的情况下，确定所述调度信息调度的数据包不采用HARQ机制；
在所述第二比特域的取值不是所述目标值的情况下，确定所述调度信息调度的数据包采用HARQ机制。
作为另一个实施例，所述方法还包括：
获取加扰所述调度信息的加扰值；
在所述加扰值为预设值的情况下，若所述第二比特域的取值为所述目标值所述调度信息调度的数据包不采用HARQ机制；若所述第二比特域的取值不是所述目标值，所述调度信息调度的数据包采用HARQ机制。若所述加扰值不是所述预设值，确定所述调度信息调度的数据包采用HARQ机制。
具体的，所述根据所述第二比特域的取值确定所述调度信息调度的数据包是否采用HARQ机制，包括：
在所述第二比特域的取值为预先设置的指示去激活HARQ的目标值的情况下，确定所述调度信息调度的数据包不采用HARQ机制；
在所述第二比特域的取值不是所述目标值的情况下，确定所述调度信息调度的数据包采用HARQ机制。
换言之，采用调度信息中指示HARQ进程号的第二比特域的特定取值(即目标值)指示去激活HARQ。若调度信息指示的HARQ进程号为所述特定取值，则不采用HARQ机制，接收端不反馈该数据包对应的HARQ-ACK，并且不缓存该数据包；反之，若调度信息指示的HARQ进程号不是所述特定取值，则采用HARQ机制，接收端反馈该数据包对应的HARQ-ACK，并且如 果解码失败则缓存该数据包到调度信息指示的HARQ进程对应的缓存中，用于后续重传的合并。
例如，约定DCI中用于指示HARQ进程号的比特域的全0状态，即HARQ进程号为0，用于指示去激活HARQ，即使用一个HARQ进程指示不采用HARQ机制的传输。假设基于RTT和传输时间间隔(Transmission Time Interval，TTI)确定要支持连续调度需要500个HARQ进程，网络侧配置HARQ进程个数，事先约定所述HARQ进程个数是否包含用于指示去激活HARQ的取值对应的一个不采用HARQ机制的进程。假设配置的HARQ进程个数包含用于指示去激活HARQ的取值对应的一个不采用HARQ机制的进程，则支持HARQ机制的进程个数为网络侧配置的HARQ进程个数减1；反之，支持HARQ机制的进程个数为网络侧配置的HARQ进程个数。
假设网络侧配置的HARQ进程个数包含用于指示去激活HARQ的取值对应的一个不采用HARQ机制的进程，且网络侧配置HARQ进程个数为501，则DCI采用9比特指示HARQ进程，网络侧既可以对所有的HARQ进程都采用HARQ机制，也可以对其中的部分HARQ进程不采用HARQ机制，此时通过将指示HARQ进程号的第二比特域设置为全0来指示。
再假设网络侧配置的HARQ进程个数包含用于指示去激活HARQ的取值对应的一个不采用HARQ机制的进程，且网络侧配置HARQ进程个数为256，则DCI采用8比特指示HARQ进程，在一个RTT当中，最多255个HARQ进程支持HARQ机制，其它的HARQ进程则可以通过将指示HARQ进程号的比特域设置为全0来指示去激活HARQ机制的传输。
再假设网络侧配置的HARQ进程个数不包含用于指示去激活HARQ的取值对应的一个不采用HARQ机制的进程，DCI可以指示的HARQ进程个数至少为网络侧配置的HARQ进程个数加1。假设网络侧配置HARQ进程个数为255，则DCI采用8比特指示HARQ进程，在一个RTT当中，最多255个HARQ进程支持HARQ机制，其它的HARQ进程则可以通过将指示HARQ进程号的比特域设置为全0来指示去激活HARQ机制的传输。
较优地，当HARQ进程为所述目标值，即不采用HARQ机制，则DCI中与HARQ相关的信息域，例如冗余版本信息、新数据指示和/或反馈信道的指 示等信息域可以重新定义用于其它的用途。
进一步地，考虑到HARQ进程号为0可能用于半持续调度或者配置的传输，在通过调度信息中指示的HARQ进程号是否为全0之前，判断加扰调度信息的RNTI，在所述RNTI为特定取值的情况下，基于调度信息中指示的HARQ进程号是否为全0判断是否去激活HARQ；否则，默认激活HARQ。例如，判断RNTI为C-RNTI时，基于调度信息中指示的HARQ进程号是否为全0判断是否去激活HARQ；而当RNTI为CS-RNTI时，默认激活HARQ。
或者，为了避免到半持续调度或者配置的传输进程号冲突，将指示HARQ进程号的比特域的全1状态用来指示去激活HARQ，网络侧通过将半持续调度、配置的传输的HARQ进程个数设置为小于总的HARQ进程个数来避免使用HARQ进程号为全1。
作为另一个可选实施例，步骤12包括：
获取所述调度信息指示的HARQ进程；调度信息包括指示HARQ进程号的比特域；
在所述调度信息指示的HARQ进程属于激活HARQ的HARQ进程集合的情况下，确定所述调度信息调度的数据包采用HARQ机制；
在所述调度信息指示的HARQ进程属于去激活HARQ的HARQ进程集合的情况下，确定所述调度信息调度的数据包不采用HARQ机制。
相应的，所述方法还包括：
获取半静态配置的下述任意一项信息：
激活HARQ的HARQ进程集合包含的HARQ进程号以及去激活HARQ的HARQ进程集合包含的HARQ进程号；
激活HARQ的HARQ进程集合包含的HARQ进程号；
去激活HARQ的HARQ进程集合包含的HARQ进程号；
激活HARQ的HARQ进程集合包含的HARQ进程的个数；
去激活HARQ的HARQ进程集合包含的HARQ进程的个数；
每个HARQ进程集合包含的HARQ进程的最大传输次数。
网络侧将HARQ进程划分为两个集合，其中一个集合中的HARQ进程都去激活HARQ功能，另一个集合中的HARQ进程都激活HARQ功能。较 优地，所述HARQ进程集合的划分为半静态的。接收端根据HARQ进程号所属的集合判断是否激活或者去激活HARQ功能。
具体地，网络侧可以通过HARQ进程号或者HARQ进程个数进行集合划分，例如分别通知每个集合中的HARQ进程；或者通知一个集合中的所有HARQ进程，其余HARQ进程属于另一个集合；或者网络侧通知一个集合中的HARQ进程个数，采用预定义的规则确定该集合对应的HARQ进程，其余的HARQ进程属于另一个集合；或者网络侧分别通知两个集合的HARQ进程个数。
例如，网络侧设备基于RTT和TTI确定要支持连续调度需要500个HARQ进程，网络侧可以分别通知激活HARQ的HARQ进程集合以及去激活HARQ的HARQ进程集合。或者，网络侧通知激活HARQ的HARQ进程集合，则其它的HARQ进程为去激活HARQ功能，反之相同。或者网络侧通知激活HARQ的HARQ进程个数，例如为M个，则进程0至进程M-1为激活HARQ功能的HARQ进程，其它进程为去激活HARQ功能的进程，反之类似。或者网络侧通知激活HARQ的HARQ进程个数，例如为M个，则进程0至进程M-1为激活HARQ功能的HARQ进程，网络侧通知去激活HARQ的HARQ进程个数，例如为N个，则进程499-N至进程499为去激活HARQ功能的HARQ进程，反之类似。
网络还可以通过配置HARQ最大传输次数进行集合划分，例如对于每个HARQ进程或者对于一组HARQ进程配置HARQ最大传输次数，若所述配置的HARQ最大传输次数为1，则表示所述HARQ进程属于去激活HARQ功能的进程集合。具体地，例如网络侧配置进程0至进程N的HARQ最大传输次数为1，其余HARQ进程的最大传输次数为8，则进程0至进程N属于去激活HARQ的HARQ进程集合，其它的HARQ进程属于激活HARQ的HARQ进程集合。
较优地，接收端根据激活HARQ的HARQ进程个数划分HARQ缓存。
较优地，对于去激活HARQ的HARQ进程，调度信息中与HARQ相关的信息域，例如冗余版本信息、新数据指示和/或反馈信道的指示等信息域可以重新定义用于其它的用途。
作为又一个可选实施例，步骤12包括：
根据加扰所述调度信息的加扰值，确定所述调度信息调度的数据包是否采用HARQ机制；例如，采用两个不同的RNTI，其中一个对应激活HARQ机制，另一个对应去激活HARQ机制，基于加扰DCI的RNTI隐式指示是否激活HARQ机制。
或者，步骤12包括：
根据所述调度信息所在的搜索空间，确定所述调度信息调度的数据包是否采用HARQ机制；例如对于每个搜索空间配置或者约定其DCI对应激活HARQ机制或者去激活HARQ机制，通过DCI所在的搜索空间隐式指示是否激活HARQ机制。
或者，步骤12包括：
根据所述调度信息的格式，确定所述调度信息调度的数据包是否采用HARQ机制；例如对于激活HARQ机制和去激活HARQ机制设计不同的DCI格式，UE盲检不同的DCI格式，通过DCI格式隐式指示是否激活HARQ机制。
或者，步骤12包括：
根据所述调度信息的长度，确定所述调度信息调度的数据包是否采用HARQ机制；例如对于激活HARQ功能的调度设计DCI长度为S1，对于去激活HARQ功能的调度设计DCI长度为S2。其中，与HARQ相关的信息域可以删除，例如HARQ进程指示、新数据指示、冗余版本指示、反馈信道的指示、等，因此较为典型地，S1>S2。终端按照两种DCI长度进行盲检，若正确解码DCI，则根据DCI长度判断当前数据包是否激活HARQ功能。
简言之，通过加扰调度信息的RNTI、调度信息所在的搜索空间、调度信息格式或者调度信息的长度隐式指示是否去激活HARQ。
综上，本公开的上述实施例通过调度信息动态指示该调度信息调度的数据包是否激活或去激活HARQ功能，从而实现针对每一个数据包动态选择是否采用HARQ机制，提升数据包传输的灵活性。
如图2所示，本公开实施例还提供一种混合自动重传请求HARQ机制的指示方法，应用于网络侧设备，包括：

进一步，较优地，当DCI指示去激活HARQ时，DCI中与HARQ相关的信息域，例如HARQ进程号、冗余版本信息、新数据指示和/或反馈信道的指示等信息域可以重新定义用于其它的用途。
作为另一个可选实施例，所述调度信息包括第二比特域，所述第二比特域用于指示HARQ进程号；
在所述第二比特域的取值为预先设置的指示去激活HARQ的目标值的情况下，所述调度信息调度的数据包不采用HARQ机制；
在所述第二比特域的取值不是所述目标值的情况下，所述调度信息调度的数据包采用HARQ机制。

较优地，当HARQ进程为所述目标值，即不采用HARQ机制，则DCI中与HARQ相关的信息域，例如冗余版本信息、新数据指示和/或反馈信道的指示等信息域可以重新定义用于其它的用途。
作为另一个可选实施例，所述方法还包括：
半静态配置下述任意一项信息：

网络侧将HARQ进程划分为两个集合，其中一个集合中的HARQ进程都去激活HARQ功能，另一个集合中的HARQ进程都激活HARQ功能。较优地，所述HARQ进程集合的划分为半静态的。接收端根据HARQ进程号所属的集合判断是否激活或者去激活HARQ功能。

网络还可以通过配置HARQ最大传输次数进行集合划分，例如对于每个 HARQ进程或者对于一组HARQ进程配置HARQ最大传输次数，若所述配置的HARQ最大传输次数为1，则表示所述HARQ进程属于去激活HARQ功能的进程集合。具体地，例如网络侧配置进程0至进程N的HARQ最大传输次数为1，其余HARQ进程的最大传输次数为8，则进程0至进程N属于去激活HARQ的HARQ进程集合，其它的HARQ进程属于激活HARQ的HARQ进程集合。
较优地，接收端根据激活HARQ的HARQ进程个数划分HARQ缓存。
较优地，对于去激活HARQ的HARQ进程，调度信息中与HARQ相关的信息域，例如冗余版本信息、新数据指示和/或反馈信道的指示等信息域可以重新定义用于其它的用途。
作为又一个可选实施例，
