Description

HARQ-ACK处理方法及装置、通信设备及存储介质 技术领域
本公开实施例涉及无线通信领域但不限于无线通信领域，尤其涉及一种混合自动重传请求应答(Hybrid Automatic Repeat request acknowledgement，HARQ-ACK)处理方法及装置、通信设备及存储介质。
背景技术
在第五代(5th Generation，5G)新无线(New Radio，NR)中，基站在调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)资源(配置为PDSCH的通信资源)时，需要为该PDSCH资源传输的数据指示其对应的HARQ-ACK传输的资源。
在5G NR非授权信道(NR-Unlicense，NR-U)中提出了一种一次性(one shot)HARQ-ACK机制，用于指示将所有HARQ进程的HARQ-ACK一次性反馈。如果基站给用户设备(User Equipment，UE)配置了一次性HARQ-ACK机制，那么UE在每次反馈HARQ-ACK时，需要一次反馈所有HARQ进程(不管是对应HARQ-ACK进程的PDSCH资源被调度了还是没调度的)的HARQ-ACK。

第一下发模块，被配置为下发在非授权信道上使用一次性HARQ-ACK机制传输HARQ-ACK的配置信令；

基于上述方案，在不触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，所述DCI包含携带第二取值的时域偏移量信息域，其中，所述第二取值不同于所述第一取值。
基于上述方案，所述DCI还包括：物理上行控制信道资源指示符PRI信息域，其中，所述PRI信息域，用于指示承载所述HARQ-ACK的PUCCH资源的资源标识。

基于上述方案，所述装置还包括：

本公开实施例提供的技术方案，在非授权信道上若为UE配置了使用一次性HARQ-ACK机制传输HARQ-ACK时，会在携带有PDSCH资源的调度指令的DCI中携带有时域偏移量信息域，若在确定要触发使用一次性HARQ-ACK机制时，则使得时域偏移量信息域携带有第一取值，而第一取值可为基站和UE都预先知道的是触发使用一次性HARQ-ACK机制进行HARQ-ACK传输的取值，如此，在不改变DCI格式的情况下，就实现了利用现有格式DCI的时域偏移量信息域触发UE使用一次性HARQ-ACK机制进行HARQ-ACK传输。且该被时域偏移量信息域携带的第一取值，还用于指示被调度的PDSCH资源与传输该PDSCH资源传输数据的HARQ-ACK的PUCCH资源之间的时域偏移量。故该时域偏移量信息域携带的第一取值具有两种功能，实现了功能复用，相对于每一种功能有一种信息域来指示，减少了信息域的数量，并减少了多个信息域所导致的信令开销。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个基站12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户 单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。该无线通信系统可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统可以是支持新空口非授权频谱通信(NR-U，New Radio-Unlicense)的系统。或者该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站12可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Medium Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
如图2所示，本实施例提供一种触发HARQ-ACK的方法，其中，应用于基站中，包括：
S110：下发在非授权信道上使用一次性HARQ-ACK机制传输HARQ-ACK的配置信令；
S120：下发调度PDSCH资源的DCI；其中，在触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，所述DCI包含携带第一取值的时域偏移量信息域，所述第一取值，还用于指示承载所述HARQ-ACK承载的物理上行控制信道PUCCH资源所在时隙和所述PDSCH资源所在时隙的偏移量。
在非授权信道上，若使用一次性HARQ-ACK机制传输HARQ-ACK，则UE会一次性将所有HARQ进程所对应的HARQ-ACK传输给基站。例如，若HARQ进程的个数为16个，则使用一次性HARQ-ACK传输HARQ-ACK时，则UE会一次性向基站发送16个HARQ进程的HARQ-ACK，则基站会接收到UE一次性上报的16个HARQ-ACK。例 如，HARQ进程的个数为8个，则使用一次性HARQ-ACK传输HARQ-ACK时，则UE会一次性向基站发送8个HARQ进程的HARQ-ACK，则基站会接收到UE一次性上报的8个HARQ-ACK。
该HARQ-ACK可包括：ACK和NACK。ACK指示数据接收成功，NACK指示数据接收失败。
该HARQ-ACK为所述PDSCH资源发送的数据的反馈信息。
该配置信令的下发可是由基站通过高层信令下发的。该高层信令包括但不限于：无线资源控制信令(Radio Resource Control，RRC)。
该配置信令的下发可在所述DCI之前，也可以与所述DCI同时下发。
该DCI携带有PDSCH资源的调度指令，该调度指令调度PDSCH资源供UE进行数据传输。
调度该PDSCH资源的DCI中包含一个k1信息域和PRI信息域。该k1信息域即为前述的时域偏移量信息域。该k1值即为时域偏移量信息域携带的任意取值。该k1信息域携带的k1值指示了HARQ-ACK所使用的时隙与PDSCH资源所在时隙之间的间隔。该PRI信息域指示了承载该HARQ-ACK的PUCCH资源的标识(Identification，ID)。根据该DCI中的k1值指示可以确定承载HARQ-ACK的PUCCH资源所在的时隙。根据需要反馈HARQ-ACK的比特数的多少可以确定PUCCH资源集合的索引，即PUCCH资源集合的ID。由于HARQ-ACK比特数的多少是基站和UE都已经知道的共同信息，因而不需要在DCI中指示。根据DCI中的信息域可以用于确定在PUCCH资源集合中使用的PUCCH资源的索引，也即PUCCH资源的ID。在还有一些情况下，在确定传输HARQ-ACK的PUCCH资源，需要联合承载该DCI的控制信道资源来一起判断PUCCH资源的ID。
在一些实施例中，在不触发使用所述一次性HARQ-ACK机制传输 HARQ-ACK时，所述DCI包含携带第二取值的时域偏移量信息域，其中，所述第二取值不同于所述第一取值。
在一些实施例中，在不触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，所述DCI可以不携带时域偏移量信息域，或者，DCI携带时域偏移量信息域时，但是该时域偏移量信息域未携带内容。
而本公开实施例中，在不触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，若在DCI中还携带有时域偏移量信息域，与触发使用一次性HARQ-ACK机制传输HARQ-ACK不同的是：域偏移量信息域携带的是第二取值。采用这种方式，相对于不携带域偏移量信息域，可以在触发和不触发的两种情况下，维持了DCI的格式不变，从而减少了DCI格式变化导致的UE盲解DCI的难度大的现象。相对于域偏移量信息域不携带内容的情况下，减少UE误以为解码错误的现象。且本公开在不触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，DCI还携带有时域偏移量信息域，且时域偏移量信息域携带有信息内容，具有与现有技术兼容性大的特点。
值得注意的是：所述第一取值可以来自第一集合，所述第二取值可来自第二集合，所述第一集合包括的备选取值个数多于所述第二集合包含的备选取值个数。
例如，所述时域偏移量信息域为3个比特，则这3个比特具有0至7这8种取值，这8种取值中的一种取值划分到第二集合中，剩余的7种取值划分到第一集合中，如此，满足所述第一取值指示不同的时隙偏移量的需求。
在一些实施例中，所述DCI还包括：PRI信息域，其中，所述PRI信息域，用于指示承载所述HARQ-ACK的PUCCH资源的资源标识。
该资源标识可至少用于确定承载所述HARQ-ACK的资源集合，然后 结合k1所指示的时隙偏移量，可以从该资源集合中选择对应的PUCCH资源传输所述HARQ-ACK。
在一些实施例中，所述方法还包括：
确定是否触发一次性HARQ-ACK机制传输所述HARQ-ACK。
所述确定是否触发一次性HARQ-ACK机制传输所述HARQ-ACK，可包括：
当下行数据缓存中没有待传输数据时，确定触发所述一次性HARQ-ACK机制；
或者，
在完成所有HARQ进程所对应的数据传输时，确定触发所述一次性HARQ-ACK机制。
如图3所示，本公开实施例还提供一种触发HARQ-ACK的方法，其中，应用于UE中，包括：
S210：接收在非授权信道上使用一次性HARQ-ACK机制传输HARQ-ACK的配置信令；
S220：接收在非授权信道上调度物理下行共享信道PDSCH资源的DCI；
S231：当所述DCI包含的时域偏移量信息域携带第一取值时，基于所述一次性HARQ-ACK机制发送所有HARQ进程的HARQ-ACK。
在本公开实施例中，UE会在非授权信道上接收到配置其使用一次性HARQ-ACK机制传输HARQ-ACK的配置信令。
UE接收到该配置信令之后，在进行HARQ-ACK传输时，会一次性将所有HARQ-ACK进程所对应数据的接收状况，生成ACK或NACK，并拼接成HARQ-ACK码本一次性反馈。
一个HARQ-ACK可对应1个比特(bit)的反馈信息，如此，在调度 N个HARQ进程用于数据传输时，则UE基于一次性HARQ-ACK机制进行HARQ-ACK传输时，则一次性会传输N个比特的HARQ-ACK。
在一些实施例中，这N个比特的排序是按照HARQ进程号的大小顺序排列的。例如，HARQ进程号较小的HARQ进程所对应的反馈信息排列在N个比特的高位，HARQ进程号较大的HARQ进程所对应的反馈信息排列的低位。
如图4所示，所述方法还包括：
S232：当所述DCI包含的时域偏移量信息域携带第二取值时，不发送HARQ-ACK；其中，所述第二取值不同于所述第一取值。
在本公开中所述时域偏移量信息域中携带的取值不同，就可以区分出基站是否触发UE使用一次性HARQ-ACK机制传输所述HARQ-ACK，同时，在指示触发使用一次性HARQ-ACK机制传输所述HARQ-ACK，第一取值还用于指示UE上传所述HARQ-ACK的PUCCH资源与物理下行共享信道(PDSCH)资源之间的时隙偏移量。此处的时隙偏移量为PDSCH资源和PUCCH资源之间相差的时隙个数。通常情况下，PDSCH资源，在时域上位于承载该PDSCH资源所数据的HARQ-ACK的PUCCH资源之前。
在一些实施例中，所述方法还包括：
根据所述DCI包含的物理上行控制信道资源指示符PRI信息域携带的PUCCH的资源标识及所述第一取值，确定承载所述HARQ-ACK的物理上行控制信道PUCCH资源的资源位置，其中，所述资源标识，用于指示承载述HARQ-ACK的PUCCH资源；所述第一取值，用于指示承载所述HARQ-ACK传输的PUCCH资源所在时隙和所述PDSCH资源所在时隙的偏移量。
如图5所示，本实施例提供一种触发HARQ-ACK的装置，应用于 基站中，包括：
第一下发模块510，被配置为下发在非授权信道上使用一次性HARQ-ACK机制传输HARQ-ACK的配置信令；
第二下发模块520，被配置为下发PDSCH资源的下行控制信息DCI；其中，在触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，所述DCI包含携带第一取值的时域偏移量信息域，所述第一取值，还用于指示承载所述HARQ-ACK承载的物理上行控制信道PUCCH资源所在时隙和所述PDSCH资源所在时隙的偏移量。
在一些实施例中，所述第一下发模块510及所述第二下发模块520可为程序模块，该程序模块被处理器执行之后，能够实现配置信令和DCI的下发。
在另一些实施例中，所述第一下发模块510及所述第二下发模块520可为软硬结合模块，该软硬结合模块包括但不限于可编程阵列；所述可编程阵列包括但不限于现场可编程阵列或复杂可编程阵列。
在还有一些实施例中，所述第一下发模块510及所述第二下发模块520可包括纯硬件模块，该纯硬件模块包括但不限于专用集成电路。
基于上述方案，在不触发使用所述一次性HARQ-ACK机制传输HARQ-ACK时，所述DCI包含携带第二取值的时域偏移量信息域，其中，所述第二取值不同于所述第一取值。
基于上述方案，所述DCI还包括：物理上行控制信道资源指示符PRI信息域，其中，所述PRI信息域，用于指示承载所述HARQ-ACK的PUCCH资源的资源标识。
