应理解,本文中术语“系统”和“网络”在本文中常可互换使用。本文中术语“和/或”用来描述关联对象的关联关系,例如表示前后关联对象可存在三种关系,举例说明,A和/或B,可以表示:单独存在A、同时存在A和B、单独存在B这三种情况。本文中字符“/”一般表示前后关联对象是“或”的关系。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。

为了清楚地阐述本申请实施例的思想,首先对通信系统中的HARQ机制的相关内容进行简要描述。
在RTT较大的场景下例如NTN系统中,为了提升gNB和UE之间的数据传输吞吐量,gNB可以为UE的某个HARQ进程配置HARQ-ACK反馈去使能。对于被配置去使能的HARQ进程,gNB不需要接收到UE反馈的HARQ-ACK信息,即可重用该HARQ进程进行数据传输。因此,gNB可以使用去使能的HARQ进程为UE进行多个数据包的调度,从而可以减少RTT带来的影响。
图2示意性地示出了下行数据传输中HARQ反馈去使能的HARQ进程7的下行传输,其中,当UE收到gNB对该HARQ进程7的调度,且该HARQ进程7对应的NDI信息翻转,那么说明该HARQ进程7用于传输新的数据包。对于HARQ进程7中传输的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)例如PDSCH 0,UE可以不需要向gNB反馈PDSCH 0的译码结果,或者,UE在向gNB反馈PDSCH 0的译码结果前可以接收gNB通过HARQ进程7调度的新的数据包。在例如NTN系统的下行数据传输中,gNB可以为UE指示去使能某个或某些下行HARQ进程,引入去使能态的HARQ进程后,UE如何确定HARQ进程的反馈时序,有待进一步研究制定和优化。
为此,本申请实施例提供一种信息处理方法,应用于终端设备,参考图3,该方法包括以下内容中的至少部分内容:
S101,终端设备获取第一配置集合,所述第一配置集合包括一个或多个与HARQ反馈时序信息对应的配置参数;
S102,所述终端设备接收第一下行控制信息DCI,所述第一DCI用于指示所述终端设备通过第一HARQ进程传输第一下行物理信道;
S103,如果所述第一HARQ进程对应使能态,则所述终端设备基于所述第一配置集合获取所述第一HARQ进程对应的HARQ反馈时序;或者,
S104,如果所述第一HARQ进程对应非使能态,则所述终端设备不获取所述第一HARQ进程对应的HARQ反馈时序。
根据本申请的实施例,所述第一配置集合可以是网络设备配置的或者是预设的。该第一配置集合中包括至少一个配置参数,配置参数与HARQ反馈时序信息对应,或者说,配置参数可以用于指示HARQ反馈时序信息。可选地,第一配置集合可以是网络设备配置的HARQ反馈时序集合。终端设备接收下行控制信息(Downlink Control Information,DCI),DCI用于指示终端设备通过某个HARQ进程(例如本文中的第一HARQ进程)传输下行物理信道,那么终端设备能够根据该第一HARQ进程对应于使能态或非使能态,来确定可以根据第一配置集合获取该第一HARQ进程对应的HARQ反馈时序,或者确定不需要获取该第一HARQ进程对应的HARQ反馈时序。
可选地,第一配置集合包括HARQ反馈时序集合。可选地,所述HARQ反馈时序集合可以是预设的或网络设备配置的。可选地,第一配置集合是标准预设的,或第一配置集合是通过第一配置信息配置的。
例如,对于DCI格式1_0调度的PDSCH,HARQ反馈时序集合是预设的;对于DCI格式1_1或DCI格式1_2调度的PDSCH,HARQ反馈时序集合可以是网络设备配置的。预设的HARQ反馈时序集合中包括多个值,网络设备配置的HARQ反馈时序集合中可以包括一个或多个值。其中,HARQ反馈时序集合中的一个值可以认为是一个配置参数,或者说,HARQ反馈时序集合中的一个值可以对应一个HARQ反馈时序信息。HARQ反馈时序集合中的值可以用K1表示。
如果HARQ反馈时序集合中包括一个值(或者说被配置一个值),则终端设备在反馈 HARQ-ACK时的传输时序是根据HARQ反馈时序集合中的该配置值确定的。如果HARQ反馈时序集合中包括多个值,则DCI格式中包括HARQ反馈时序指示(PDSCH-to-HARQ_feedback timing indicator)信息,或简称为HARQ timing信息。HARQ反馈时序指示信息用于从HARQ反馈时序集合中动态指示HARQ反馈资源的时域位置例如HARQ反馈资源的时隙。
作为示例,HARQ反馈时序集合中包括8个值,HARQ反馈时序指示信息包括3比特,该HARQ反馈时序指示信息为000时,指示HARQ反馈时序集合中的第一个K1值,该HARQ反馈时序指示信息为001时,指示HARQ反馈时序集合中的第二个K1值,等等。终端设备在反馈HARQ-ACK时的传输时序是根据DCI中的HARQ反馈时序指示信息指示的HARQ反馈时序集合中的K1值确定的。
可选地,HARQ反馈时序集合中的K1值可以包括有效值和/或无效值。
可选地,有效值也可以称为有效K1值或可用的K1值。有效K1值可以指:该K1值对应可用的HARQ反馈时序信息,或终端设备可以根据该K1值确定有效的HARQ反馈时序。作为示例,有效K1值的取值大于或等于0。
可选地,无效值也可以称为无效K1值或不可用的K1值。无效K1值可以指:该K1值对应不可用的HARQ反馈时序信息,或终端设备不能根据该K1值确定有效的HARQ反馈时序。作为示例,无效K1值的取值为-1。
相对应地,本申请还提供一种信息处理方法,应用于网络设备,参考图4,所述方法包括:
S201,网络设备向终端设备发送第一配置集合,所述第一配置集合包括一个或多个与HARQ反馈时序信息对应的配置参数;
S202,所述网络设备向所述终端设备发送第一下行控制信息DCI,所述第一DCI用于指示所述终端设备通过第一HARQ进程传输第一下行物理信道;
其中,在所述第一HARQ进程对应使能态时,所述第一配置集合用于所述终端设备基于所述第一配置集合获取所述第一HARQ进程对应的HARQ反馈时序;或者,在所述第一HARQ进程对应非使能态时,所述第一配置集合不用于所述终端设备获取所述第一HARQ进程对应的HARQ反馈时序。
利用本申请的实施例,终端设备可以根据用于传输下行物理信道的HARQ进程对应的非使能态或使能态,来确定如何获取HARQ反馈时序。利用本申请至少一个实施例,在调度下行物理信道传输的下行控制信息中可以不包括HARQ反馈时序指示信息,可节省信令开销。
在本申请实施例中,HARQ进程的状态可以包括使能态和非使能态。可选地,随着标准的演进,也可以包括更多种状态,例如半使能态等,本申请并不限于此。
可选地,在本申请实施例中,每个HARQ进程具有对应的状态,其中,HARQ进程对应的状态也可以表述为HARQ进程的状态,或者,表述为HARQ进程被配置为使能态或非使能态。
从HARQ-ACK反馈的角度来讲,HARQ进程的状态为使能态或非使能态也可以表述为HARQ进程对应的HARQ反馈功能状态可以为使能态或非使能态。或者说,HARQ进程对应的HARQ反馈功能状态被配置为使能态或非使能态。
在本申请实施例中,非使能态也被称为去使能(disabled)态。
可选地,在一些实施例中,所述HARQ进程的状态可以是高层信令配置的,或者,也可以是通过动态信令,例如DCI动态指示的,或者,也可以是隐式确定的,本申请对于HARQ进程的状态的配置方式不作限定。

可选地,如果所述HARQ反馈时序指示信息指示所述第二类配置参数中的第五配置参数,则所述终端设备确定所述第一HARQ进程对应非使能态,所述终端设备不获取所述第一HARQ进程对应的HARQ反馈时序,或者,所述终端设备确定所述第一HARQ进程对应的HARQ反馈时序与所述第五配置参数相对应。或者,如果所述HARQ反馈时序指示信息指示第五配置参数,所述第五配置参数属于第二类配置参数(或者说,所述第五配置参数为无效K1值),则所述终端设备确定所述第一HARQ进程对应非使能态,所述终端设备不获取所述第一HARQ进程对应的HARQ反馈时序,或者,所述终端设备确定所述第一HARQ进程对应的HARQ反馈时序与所述第五配置参数相对应。

作为一个示例,假设HARQ反馈时序集合中包括1个无效K1值(例如K1=-1)和N个有效K1值,N大于或等于1,第一DCI对应的DCI格式中包括的HARQ反馈时序指示信息域的比特数是根据ceil(log2(N+1))确定的,其中,ceil()表示上取整操作。例如N=2时,第一DCI中包括的HARQ反馈时序指示信息域的比特数为2比特。

情况四:第一DCI对应第一DCI格式或第二DCI格式
在本申请的实施例中,可选地,如果所述第一DCI对应第一DCI格式,所述第一DCI格式中不包括HARQ反馈时序指示信息,那么,所述终端设备确定所述第一HARQ进程对应非使能态,所述终端设备不获取所述第一HARQ进程对应的HARQ反馈时序。
在本申请的实施例中,可选地,如果所述第一DCI对应第二DCI格式,所述第二DCI格式中包括HARQ反馈时序指示信息,那么,所述终端设备确定所述第一HARQ进程对应使能态,并基于所述第二DCI格式中的HARQ反馈时序指示信息指示的所述第一配置集合中的配置参数,获取所述第一HARQ进程对应的HARQ反馈时序。
可选地,UE可以根据第一DCI确定第一HARQ进程对应非使能态或使能态。例如,第一DCI格式对应非使能态的HARQ进程的调度,第二DCI格式对应使能态的HARQ进程的调度。如果UE收到的第一DCI对应第一DCI格式,那么UE确定第一HARQ进程对应非使能态,或者,如果UE收到的第一DCI对应第二DCI格式,那么UE确定第一HARQ进程对应使能态。
可选地,第一DCI格式包括DCI格式1_1或DCI格式1_2或除DCI格式1_0外的一种DCI格式。
可选地,第二DCI格式包括DCI格式1_0。
可选地,第二DCI格式中包括HARQ反馈时序指示信息域,如前所述,HARQ反馈时序指示信息域用于动态指示HARQ反馈资源的时域位置例如HARQ反馈资源的时隙,用K1表示。
作为一个示例,例如HARQ反馈时序指示信息包括3比特,该HARQ反馈时序指示信息为000时,指示HARQ反馈时序集合中的第一个值,该HARQ反馈时序指示信息为001时,指示HARQ反馈时序集合中的第二个值,等等。
可选地,HARQ反馈时序集合中包括至少两个有效K1值。作为示例,HARQ反馈时序集合可以是通过第一配置信息例如dl-DataToUL-ACK或dl-DataToUL-ACKForDCIFormat1_2配置的。
作为一个示例,假设HARQ反馈时序集合中包括N个K1值,N大于或等于2,第二DCI格式中包括的HARQ反馈时序指示信息域的比特数是根据ceil(log2(N))确定的。例如N=3时,第二DCI格式中包括的HARQ反馈时序指示信息域的比特数为2比特。
对于上述任一个实施例或多个实施例的组合,可选地,UE在确定第一HARQ进程对应的HARQ反馈时序时,还考虑偏移值Koffset。可选地,Koffset值是根据往返时间RTT或定时提前TA确定的。可选地,Koffset值是gNB指示的,或Koffset值是UE自行确定的,或Koffset值是预设的。
在本申请的实施例中,可选地,所述第一指示信息还用于指示第一HARQ进程集合和/或第二HARQ进程集合中的HARQ进程数,所述第一HARQ进程集合中包括对应使能态的HARQ进程,所述第二HARQ进程集合中包括对应非使能态的HARQ进程,则所述终端设备可以根据所述第一HARQ进程所属的HARQ进程集合确定所述第一HARQ进程对应使能态或者非使能态。
通过上述多个实施例中的任一实施例或者多个实施例的组合,本申请实施例的终端设备能够确定如何获取HARQ反馈时序。以下通过具体的例子,描述本申请实施例的具体实现过程。
在本申请的实施例中,可选地,UE接收gNB发送的RRC配置信息,该RRC配置信息用于配置上行HARQ-ACK反馈去使能的下行HARQ进程。其中,UE被配置的HARQ进程数为16,该RRC配置信息用于配置第二HARQ进程集合中的HARQ进程数为1,则UE可以确定第二HARQ进程集合中包括HARQ进程0,第一HARQ进程集合中包括HARQ进程1~15。该RRC配置信息还用于配置第二HARQ进程集合为上行HARQ-ACK反馈去使能的HARQ进程集合。即,HARQ进程0对应非使能态,HARQ进程1~15对应使能态。
UE被配置的调度PDSCH的DCI格式中不包括HARQ反馈时序指示信息域,且UE被gNB通过高层参数(即第一配置信息)例如dl-DataToUL-ACK或dl-DataToUL-ACKForDCIFormat1_2配置一个有效K1值(即第一配置参数)。
①当UE收到gNB通过第一DCI调度的使用第一HARQ进程传输的第一PDSCH时,如果第一HARQ进程对应使能态,则UE根据高层参数配置的有效K1值确定第一PDSCH的译码结果对应的HARQ反馈时序。
②当UE收到gNB通过第一DCI调度的使用第一HARQ进程传输的第一PDSCH时,如果第一HARQ进程对应非使能态,则UE不确定第一PDSCH的译码结果对应的HARQ反馈时序,或UE确定不反馈第一PDSCH的译码结果。
如图5所示,如果UE收到DCI调度的PDSCH 0,且该PDSCH 0对应的HARQ进程属于第二HARQ进程集合,例如为HARQ进程1,则UE根据高层参数(第一配置信息)配置的有效K1值确定PDSCH 0对应的HARQ反馈时序,进而确定PDSCH 0的译码结果对应的PUCCH资源的时域位置。
如果UE收到DCI调度的PDSCH 1,PDSCH 2或PDSCH 3,且该PDSCH 1,PDSCH 2或PDSCH 3对应的HARQ进程属于第一HARQ进程集合,例如均为HARQ进程0,则UE不确定PDSCH 1,PDSCH 2或PDSCH 3对应的HARQ反馈时序,或UE确定不反馈PDSCH 1,PDSCH 2或PDSCH 3的译码结果。
根据本申请的以上至少一个实施例,当UE被配置某个或某些HARQ进程对应非使能 态时,调度PDSCH传输的DCI格式中可以不包括HARQ反馈时序指示信息,UE根据用于传输PDSCH的HARQ进程对应的非使能态或使能态,确定是否根据高层配置参数确定HARQ反馈时序,可以减小DCI中的信令开销。

利用本申请的实施例,终端设备可以根据用于传输下行物理信道的HARQ进程对应于非使能态或使能态,来确定如何获取HARQ反馈时序。利用本申请中的部分实施例,在调度下行物理信道传输的下行控制信息中可以不包括HARQ反馈时序指示信息,可节省信令开销。
