在又一个可能的实现方式中,在S212中,UE还可以根据第一目标DCI的格式是否为预定DCI格式,以及第一目标DCI调度的目标上行信道为所述配置授权对应的PUSCH来确定目标上行信道的传输参数。在该可能的实现方式中,S212可以包括:在所述第一目标DCI的格式为预定DCI格式,且所述第一目标DCI调度的所述目标上行信道为所述配置授权对应的PUSCH(即第一目标DCI用于激活配置授权PUSCH)的情况下,根据目标资源和所述配置授权中的重复参数,确定所述目标上行信道的传输参数。

可选地,根据目标资源和所述配置授权中的重复参数,确定所述目标上行信道的传输参数,包括:在所述重复参数的值大于1的情况下,根据所述目标资源配置或关联的目标信息,确定所述目标上行信道的多个目标空间关系和/或多个目标路损参考信号。也就是说,在重复参数指示进行重复传输的情况下,根据所述目标资源配置或关联的目标信息,确定所述目标上行信道的多个目标空间关系和/或多个目标路损参考信号。
在上述可能的实现方式中,可选地,所述目标资源可以包括:

通过本申请实施例提供的上述方法,可以实现不同DCI格式的DCI分别调度分别单TRP和多TRP传输,从而可以使得单TRP场景的DCI开销能得到有效降低,提升调度的可靠性。
在DCI在调度PUSCH时,带宽部分(Bandwidth Part,BWP)指示域可以指示一个与当前激活的BWP不同的BWP,以实现上行BWP切换。当从多TRP配置的BWP切换到单TRP配置的BWP或者从单TRP配置的BWP切换到多TRP配置的BWP时,解读目标BWP所需要的目标域的数量与接收到的DCI中包含的目标域的数量可能不相同,从而可能导致终端不知道该如何对DCI各个域进行解读,进而可能会造成终端与网络调度理解不一致, 造成调度失败,进一步影响数据的传输可靠性与时延。针对该问题,本申请实施例提供了一种DCI解析方法。
图3示出本申请实施例中的DCI解析方法的一种流程示意图,该方法300可以由终端执行。换言之,所述方法可以由安装在终端上的软件或硬件来执行。如图3所示,该方法可以包括以下步骤。
S310,终端接收第二目标DCI,其中,所述第二目标DCI的BWP指示域指示的目标BWP不是激活的BWP;
S312,根据所述第二目标DCI中包含的目标域的数量X与调度所述目标BWP需要解读的所述目标域的数量Y,对所述第二目标DCI中的所述目标域进行解析,其中,X和Y为大于或等于0的整数。
在一个可能的实现方式中,根据所述第二目标DCI中包含的目标域的数量X与调度所述目标BWP需要解读的所述目标域的数量Y,对所述第二目标DCI中的所述目标域进行解析,包括:在X大于或等于Y的情况下,解析所述第二目标DCI中的前或后Y个的所述目标域。在该可能的实现方式中,在第二目标DCI中包含的目标域的数量X大于或等于调度所述目标BWP需要解读的所述目标域的数量Y时,只解析所述第二目标DCI中的前或后Y个的所述目标域。例如,在从多TRP配置的BWP切换到单TRP配置的BWP时,第二目标DCI中包含的目标域的数量为N(N>1),调度所述目标BWP需要解读的所述目标域的数量为1,则只解析第二目标DCI中包含的第一个目标域。
在上述可能的实现方式中,可选地,在Y为0的情况下,不解析所述第二目标DCI中的所述目标域。
在一个可能的实现方式中,根据所述第二目标DCI中包含的目标域的数量X与调度所述目标BWP需要解读的所述目标域的数量Y,对所述第二目标DCI中的所述目标域进行解析,包括:在X小于Y的情况下,所述终端假定所述第二目标DCI中包含Y个目标域,其中,所述Y个目标域由Y-X 个目标域与所述第二目标DCI中的X个目标域顺序组成,或者由所述X个目标域与所述Y-X个目标域顺序组成,所述Y-X个目标域的值为0;对Y个所述目标域进行解析。也就是说,在该可能的实现方式中,如果X小于Y,则在X个目标域的前面补值为0的Y-X个目标域,或在X个目标域的后面被值为0的Y-X个目标域,补的比特数与Y-X个目标域所包含的比特数相同。
在上述可能的实现方式中,在X为0的情况下,所述终端假定所述目标BWP上没有对应目标域。即在X为0时,终端认为目标BWP上没有对应的目标域。
或者,在另一个可能的实现方式中,根据所述第二目标DCI中包含的目标域的数量X与调度所述目标BWP需要解读的所述目标域的数量Y,对所述第二目标DCI中的所述目标域进行解析,包括:在X小于Y的情况下,所述终端假定所述目标BWP上仅有X个有效SRS资源集与所述第二目标DCI中的X个所述目标域关联;按照所述X个有效SRS资源集对所述第二目标DCI中的X个所述目标域进行解析。
在上述可能的实现方式中,所述X个有效SRS资源集包括以下之一:所述目标BWP配置的多个SRS资源集按照目标顺序进行排序后的前或后X个效SRS资源集;
其中,所述目标顺序包括以下之一:
配置顺序;
索引值从大到小的顺序;
索引值从小到大的顺序;
与Y个目标域的关联顺序。
在又一个可能的实现方式中,根据所述第二目标DCI中包含的目标域的数量X与调度所述目标BWP需要解读的所述目标域的数量Y,对所述第二目标DCI中的所述目标域进行解析,包括:在所述X不等于Y的情况下,所述终端解析所述第二目标DCI中的一个目标域;其中,所述一个目标域包 括以下之一:所述第二目标DCI中的第一个目标域;所述第二目标DCI中与一个目标SRS资源集对应的目标域,其中,所述目标SRS资源集为所述目标BWP或激活BWP上配置的多个SRS资源集中的一个。
在上述可能的实现方式中,所述目标SRS资源集为所述目标BWP或激活BWP上配置的多个SRS资源集中索引值最小的一个SRS资源集。
在一个可能的实现方式中,在对所述第二目标DCI中的所述目标域进行解析之前,所述方法还包括:
在所述第二目标DCI的所述目标域所占的第一比特数小于调度所述目标BWP需要解读的所述目标域(即目标BWP上的DCI中的目标域)所占的第二比特数的情况下,在所述第二目标DCI的目标域的比特串前补零,直到所述比特串的长度为所述第二比特数;和/或,
在所述第一比特数大于或等于所述第二比特数的情况下,从所述第二目标DCI的目标域的比特串的最低有效比特位开始,删除其中的部分比特,使得所述比特串的长度为所述第二比特数。
例如,所述第二目标DCI的所述目标域所占的比特数为x,目标BWP的DCI的所述目标域所占的比特数为y,如果x<y,则在第二目标DCI的目标域的x个比特前补(y-x)个0,如果x<=y,则从最低位开始,从第二目标DCI的目标域的x个比特中删除(x-y)个比特。
在上述各个可能的实现方式中,可选地,所述目标域包括但不限于以下至少一项:
动态切换指示域;
SRI域;
TPMI域;
TPC域;
PTRS-DMRS关联域;
开环功率控制参数集指示。
在上述各个可能的实现方式中,可选地,所述第二目标DCI中的SRI域对应指示激活BWP上配置的SRS资源集中的SRS资源。
例如,UE接收DCI,所述DCI包含BWP指示域,该BWP指示域指示的BWP(即目标BWP)不是当前激活的BWP(当前BWP),则所述DCI的解读方法如下:
对于某个信息域I,所述DCI包含X个信息域I,目标BWP上的调度需要解读Y个信息域I。
(1)如果X>Y,则:
(1.1)UE只翻译当前DCI的前或后Y个信息域I;
(1.2)如果Y=0,则UE不解读当前DCI的所述信息域I。
(2)如果X<Y,则:
(2.1)UE假定当前DCI有Y个信息域I,其中前Y-X个信息域补0,或者其中后Y-X个信息域补0。其中,补0的比特数与目标BWP所需要的对应信息域I的比特数相同。
特别地,如果X=0则UE假定目标BWP没有信息域I。
(2.2)UE假定目标BWP上DCI的前/后Y-X个目标域无效。
UE假定目标BWP上仅有X个有效SRS资源集与所述DCI的X个信息域关联。
其中,所述SRS资源集按照配置顺序取前/后X个SRS资源集;或者,
所述SRS资源集按照索引值大小排序,前/后X个SRS资源集;或者,
所述SRS资源集按照与目标BWP的DCI中的Y个信息域I的关联顺序排序,取前/后X个SRS资源集;
(3)如果X不等于Y,UE假定只有一个信息域I生效。
(3.1)所述信息域I为第一个信息域I。
(3.2)UE假定当前BWP或目标BWP上仅有一个用于PUSCH传输的SRS resource set。可选地,所述SRS resource set为索引值小的一个SRS资 源集。
对于以上情况,如果当前DCI的信息域I的大小小于目标BWP上DCI对应的信息域I的大小,则对当前信息域I前面补零,如果大于则从当前信息域I的最低有效比特使其等于目标BWP上的DCI对应的信息域I。
信息域I为以下至少一种:
SRI域;
TPMI域;
TPC域;
PTRS-DMRS关联域;
开环功率控制参数集指示域。
其中,接收到的DCI的SRI field对应指示的是当前BWP配置的SRS resource set。
例如,当前DCI包含两个SRI域,当前DCI的BWP指示域指示的BWP配置了两个用于码本或非码本传输的SRS资源集,则所需要的SRI域也是两个,UE认为当前DCI的两个SRI域与目标BWP上配置的两个SRS资源集一一关联。
又例如,当前DCI包含两个SRI域,当前DCI的BWP指示域指示的BWP配置了两个用于码本或非码本传输的SRS资源集,其中一个SRS资源集仅配置了一个SRS资源,则其所需要的SRI域是两个,其中一个域的比特大小是0,则UE认为当前DCI的第一个SRI域与目标BWP上所需要的SRI域对应,第二个SRI域的比特大小是0。
又例如,当前DCI包含两个SRI域,当前DCI的BWP指示域指示的BWP配置了一个用于码本或非码本传输的SRS资源集,则其所需要的SRI域是1个,则UE认为当前DCI的第一个SRI域与目标BWP上所需要的SRI域对应。
