示例地,在本公开实施例中,网络设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或预编码传输或波束赋形传输等。
在一些无线通信系统,例如新空口(new radio,NR)系统、长期演进(long term evolution,LTE)系统等中,支持单码字传输和两码字传输。在下行控制信息(downlink control information,DCI)包括1个或2个传输块(transport block,TB),一个TB可以理解为一个码字(codeword,CW)。
在当前的NR系统中,只有下行共享信道(physical downlink Share channel,PDSCH)支持2码字传输。基于码本的上行共享信道(physical uplink share channel,PUSCH)传输的预编码,是基于基站指示的预编码矩阵确定的,基于非码本PUSCH传输的预编码是基于基站指示的探测参考信号(sounding reference signaling,SRS)资源确定的,且传输层数等于基站指示的SRS资源的数目。
随着PUSCH传输支持的天线端口数的增多,PUSCH传输对应的预编码矩阵的数目、层数和探测参考信号资源的数目均会增加,使得通过上行调度信息指示预编码矩阵、层数或者信道探测参考信号资源时,会导致上行调度信息中用于指示预编码矩阵、层数或者信道探测参考信号资源的指示信息开销较大的问题。
为了解决随着天线端口数的增多,导致的用于指示预编码矩阵、层数或者信道探测参考信号资源的指示信息开销较大的问题,本公开实施例提供了一种信息确定方法,终端接收网络设备发送的第一传输对应的参数信息和指示信息,参数信息用于确定码字个数,指示信息用于指示目标信息,目标信息包括预编码矩阵、层数或者信道探测参考信号资源中的至少一个;并基于参数信息和指示信息,确定第一传输对应的目标信息。这样结
合用于确定第一传输的码字个数的参数信息共同确定第一传输对应的目标信息,可以有效地降低指示信息的开销,从而解决了随着天线端口数的增多,导致的用于指示预编码矩阵、层数或者信道探测参考信号资源的指示信息开销较大的问题,从而降低了指示信息开销。
示例地,在执行本公开实施例提供的技术方案之前,可以先确定第一传输对应的天线端口数量,在第一传输对应的天线端口数量为预设数量的情况下,例如,天线端口数量为8,可以执行本公开实施例提供的信息确定方法,即基于参数信息和指示信息,确定第一传输对应的目标信息。否则,可以采用现有的信息确定方法,确定第一传输对应的目标信息,具体可以根据实际需要进行设置。
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,并不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
图1为本公开实施例提供的信息确定方法的流程示意图一,该信息确定方法可应用于终端,例如,手机等。示例地,请参见图1所示,该信息确定方法可以包括:
S101、接收网络设备发送的第一传输对应的参数信息和指示信息,参数信息用于确定码字个数,指示信息用于指示目标信息,目标信息包括预编码矩阵、层数或者信道探测参考信号资源中的至少一个。
示例地,第一传输可以为PUSCH传输,也可以为PDSCH传输等,具体可以根据实际需要进行设置。以PUSCH传输为例,其具体可以为:在PUSCH上进行数据的传输,或者,传输PUSCH携带的信息等。
示例地,在本公开实施例中,参数信息可以包括下述至少一种:
码字个数信息;
第一传输的调制编码方式MCS指示信息;
第一传输的冗余版本RV指示信息。
可以理解的是,当所述参数信息包括码字个数信息时,可以理解为网络设备显示地向终端指示第一传输的码字个数;当参数信息包括第一传输的调制编码方式MCS指示信息和第一传输的冗余版本RV指示信息时,可以理解为网络设备隐式地向终端指示第一传输的码字个数。
可选的,一个码字对应一个传输块TB(Transmission block)。以第一传输为PUSCH传输为例,在确定码字个数时,若PUSCH传输的调度信息中只有一个TB对应的控制信息使能,则可以确定PUSCH传输的码字个数为1,即PUSCH传输的调度信息中包括的2个TB中,另一个TB对应的控制信息非使能。若PUSCH传输的调度信息中包括的2个TB对应的控制信息都被使能,则可以确定PUSCH传输的码字个数为2。
可以理解的是,在本公开实施例中,指示以第一传输支持2码字的情况为例进行说明,但并不局限于2个码字,也可以3码字,4码字等,具体可以根据实际需要进行设置。
在分别获取到用于确定码字个数的参数信息,和用于指示目标信息的指示信息后,就可以执行下述S102:
S102、基于参数信息和指示信息,确定第一传输对应的目标信息。
示例地,在本公开实施例中,基于参数信息和指示信息,确定第一传输对应的目标信息时,可以先基于参数信息,确定码字个数;再基于码字个数和指示信息,确定第一传输对应的目标信息。
示例地,基于参数信息,确定码字个数时,若一个TB对应的MCS指示信息和RV指示信息对应于给定值时,则说明TB对应的目标信息非使能。例如,一个TB对应的MCS指示信息MCS=26,RV指示信息RV=1时,则说明TB对应的目标信息非使能。又例如,一个TB对应的MCS指示信息MCS=0,RV指示信息RV=0时,则说明TB对应的目标信息非使能;否则,说明TB对应的控制信息使能,具体可以根据实际需要进行设置。在本示例中,一个TB的目标信息非使能意味着不能使用该目标信息进行传输。
示例地,基于参数信息和指示信息,确定第一传输对应的目标信息时,
若参数信息为TB对应的MCS指示信息和RV指示信息时,基于TB对应的MCS指示信息、RV指示信息和指示信息,确定第一传输对应的目标信息。
示例地,指示信息可以为基于预设比特编码进行编码得到的指示信息。
示例地,在本公开实施例中,基于码字个数和指示信息,确定第一传输对应的目标信息时,可以先确定预设的映射关系,其中,预设的映射关系用于表征指示信息和目标信息之间的映射关系;并根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的目标信息。其中,预设的映射关系用于表征指示信息和目标信息之间的映射关系。
示例地,预设的映射关系的表达方式包括下述至少一种:
码本方式;
表格方式;
位图方式;
函数方式。
需要说明的是,在描述预设的映射关系的表达方式时,本公开实施例中只是以上述至少一种表达方式为例进行说明,但并不代表本公开实施例仅局限于此。
可以看出,本公开实施例中,终端通过接收网络设备发送的第一传输对应的参数信息和指示信息,参数信息用于确定码字个数,指示信息用于指示目标信息,目标信息包括预编码矩阵、层数或者信道探测参考信号资源中的至少一个;并基于参数信息和指示信息,确定第一传输对应的目标信息。这样结合用于确定第一传输的码字个数的参数信息共同确定第一传输对应的目标信息,可以有效地降低指示信息的开销,从而解决了随着天线端口数的增多,导致的用于指示预编码矩阵、层数或者信道探测参考信号资源的指示信息开销较大的问题,从而降低了指示信息开销。
为了便于理解在本公开实施例中,如何根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的目标信息,下面,将结合两种
不同的场景进行描述。示例地,一种可能的场景为基于码本的PUSCH传输场景,另一种可能的场景为基于非码本的PUSCH传输。
示例地,当网络设备为终端配置基于码本的PUSCH传输时,目标指示域为第二传输预编码矩阵指示(transmission pre-coding matrix indicator,TPMI)域;当网络设备为终端配置基于非码本的PUSCH传输时,目标指示域为第二探测参考信号(sounding reference signaling,SRI)域。
示例地,在一种可能的场景中,即基于码本的PUSCH传输场景。在基于码本的PUSCH传输场景中,通常需要确定PUSCH传输对应的预编码矩阵和层数,并基于PUSCH传输对应的预编码矩阵和/或层数,进行PUSCH传输。
可以理解的是,在本公开实施例中,在确定PUSCH传输对应的预编码矩阵和层数时,预编码矩阵和层数可以独立指示,即预编码矩阵和层数均对应有各自的指示信息,也可以联合指示,即编码矩阵和层数对应一个指示信息,基于该指示信息可以同时确定预编码矩阵和层数。
示例地,在该种可能的场景中,为了便于理解根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的目标信息,可以包括下述至少三种可能的实现方式:
在一种可能的实现方式中,PUSCH传输对应的目标信息包括预编码矩阵。在根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的预编码矩阵时,在码字个数为第一数量的情况下,指示信息指示的预编码矩阵为第一层数范围内的层数对应的预编码矩阵。
在码字个数为第二数量的情况下,指示信息指示的预编码矩阵为第二层数范围内的层数对应的预编码矩阵;其中,第一层数范围和第二层数范围不同。
示例地,在本公开实施例中,第一层数范围和第二层数范围的层数最大值是基于下述一项或多项确定的:
基于层数限制信息确定的最大层数;
网络设备配置的层数;
终端支持的最大层数。
可以理解的是,在本公开实施例中,层数限制信息可以用于指示最大层数的信息;也可以是用来指示层数的取值范围的信息;例如,指示PUSCH传输只能是1、2、4、6层等。
示例地,在本公开实施例中,用于指示预编码矩阵的指示信息的比特宽度是基于第一层数范围,和/或,第二层数范围确定的。
示例地,在基于第一层数范围和第二层数范围共同确定指示信息的比特宽度时,可以分别确定第一层数范围内的层数对应的预编码矩阵的数量,和第二层数范围内的层数对应的预编码矩阵的数量,将该两个数量中的最大值,确定为用于指示预编码矩阵的指示信息的比特宽度。
示例地,在本公开实施例中,以PUSCH传输支持的天线端口数量为8为例,在PUSCH的码字个数为1的情况下,指示信息指示的预编码矩阵为层数不大于4的层数对应的预编码矩阵,即码字个数为1的情况下,第一层数范围可以为层数1至层数4的层数范围;在PUSCH的码字个数为2的情况下,指示信息指示的预编码矩阵为层数大于4的层数对应的预编码矩阵,即码字个数为2的情况下,第一层数范围可以为层数5至层数8的层数范围,具体可以根据实际需要进行设置,在此,本公开实施例只是以此为例进行说明,但并不代表本公开实施例仅局限于此。
在该种可能的实现方式中,以预设的映射关系包括码本方式为例,示例地,在根据基于码字个数、指示信息,以及预设的码本,确定第一传输对应的预编码矩阵时,可参见下述实施例1。

步骤2、在确定PUSCH的码字个数为1的情况下,基于指示信息和第一码本确定PUSCH传输对应的预编码矩阵;在确定PUSCH的码字个数为2的情况下,基于指示信息和第二码本确定PUSCH传输对应的预编
码矩阵。
示例地,第一码本可以为层数不大于4的层数对应的预编码矩阵构成的码本,第二码本可以为层数不大于4的层数对应的预编码矩阵构成的码本。
示例地,当预设的映射关系包括码本方式时,用于指示预编码矩阵的指示信息的比特宽度是基于第一码本中包括的预编码矩阵的数量,和/或,第二码本中包括的预编码矩阵的数量确定的。
示例地,在本公开实施例中,用于指示预编码矩阵的指示信息的比特宽度可以为2,即指示信息为2比特,具体可以根据实际需要进行设置。
示例地,在基于第一码本中包括的预编码矩阵的数量和第二码本中包括的预编码矩阵的数量确定共同确定指示信息的比特宽度时,可以将该两个数量中的最大值,确定为用于指示预编码矩阵的指示信息的比特宽度。

示例地,第一表格中任意一个entry指示的预编码矩阵对应的层数均不大于4,第二表格中任意一个entry指示的预编码矩阵对应的层数均大于4。
示例地,以天线端口数量为8为例,层数信息可以为2比特,在确定PUSCH的码字个数为1的情况下,基于指示信息和第一表格确定PUSCH
传输对应的预编码矩阵时,可参见下述表1,即PUSCH的码字个数为1的情况,对应第一表格;在确定PUSCH的码字个数为2的情况下,基于指示信息和第二表格确定PUSCH传输对应的预编码矩阵是,可参见下述表2,即PUSCH的码字个数为2的情况,对应第二表格。
表1
结合表1可以看出,在确定PUSCH的码字个数为1的情况下,指示信息为0时,对应确定出的预编码矩阵为层数1对应的预编码信息中的预编码矩阵;在确定PUSCH的码字个数为1的情况下,指示信息为1的情况下,对应确定出的预编码矩阵为层数2对应的预编码信息中的预编码矩阵;在确定PUSCH的码字个数为1的情况下,指示信息为2的情况下,对应确定出的预编码矩阵为层数3对应的预编码信息中的预编码矩阵;在确定PUSCH的码字个数为1的情况下,指示信息为3时,对应确定出的预编码矩阵为层数4对应的预编码信息中的预编码矩阵。
表2
结合表1可以看出,在确定PUSCH的码字个数为2的情况下,指示信息为0时,对应确定出的预编码矩阵为层数5对应的预编码信息中的预编码矩阵;在确定PUSCH的码字个数为2的情况下,指示信息为1的情况下,对应确定出的预编码矩阵为层数6对应的预编码信息中的预编码矩

在该种可能的实现方式中,以预设的映射关系包括编码方式为例,示例地,在根据基于码字个数、指示信息,以及预设的码本,确定第一传输对应的预编码矩阵时,可参见下述实施例3。
实施例3
步骤1、接收网络设备发送的PUSCH传输的调度消息;其中,调度消息包括PUSCH传输的参数信息和指示信息,参数信息用于确定码字个数,指示信息用于指示预编码矩阵。
步骤2、在确定PUSCH的码字个数为1的情况下,基于指示信息和第一编码方式确定PUSCH传输对应的预编码矩阵;在确定PUSCH的码字个数为2的情况下,基于指示信息和第二编码方式确定PUSCH传输对应的预编码矩阵。
示例地,第一编码方式中任意一个指示信息的取值对应的层数均不大于4,第二编码方式中任意一个指示信息的取值对应的层数均大于4。
基于上述描述可以看出,在maxRank大于4,且PUSCH的码字个数为2的情况下,基于第二表格确定PUSCH传输对应的预编码矩阵,和/或,基于第二码本确定PUSCH传输对应的预编码矩阵;PUSCH的码字个数为1的情况下,基于第一表格确定PUSCH传输对应的预编码矩阵,和/或,基于第一码本确定PUSCH传输对应的预编码矩阵。
和/或,

其中,第三表格中的任意一个用于指示预编码矩阵的entry指示的预编码矩阵对应的层数为1到maxRank中的一项;第三码本为层数为1到maxRank的预编码矩阵构成的码本。
其中,maxRank是基于层数限制信息确定的最大层数,或者,PUSCH可以被调度的最大MIMO层数,即网络设备配置的层数;或者,UE支持的PUSCH可以传输的最大MIMO层数,即终端支持的最大层数终端中至少一种确定的。
示例地,在本公开实施例中,用于调度PUSCH的DCI类型DCI format 0_1和DCI format 0_2可以对应同一个maxRank参数。也可以对应不同的maxRank参数,例如,一个用maxRankDCI-0-1指示,一个用maxRankDCI-0-2指示,具体可以根据实际需要进行设置,在此,本公开实施例不做具体限制。
在另一种可能的实现方式中,PUSCH传输对应的目标信息包括层数。在根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的层数时,在码字个数为第一数量的情况下,指示信息指示的层数为第一层数范围内的层数。
在码字个数为第二数量的情况下,指示信息指示的层数为第二层数范围内的层数;其中,第一层数范围和第二层数范围不同。
示例地,在本公开实施例中,第一层数范围和第二层数范围的层数最大值是基于下述一项或多项确定的:
基于层数限制信息确定的最大层数;
网络设备配置的层数;
终端支持的最大层数。
示例地,在本公开实施例中,用于指示预编码矩阵的指示信息的比特宽度是基于第一层数范围,和/或,第二层数范围确定的。
示例地,在基于第一层数范围和第二层数范围共同确定指示信息的比特宽度时,可以分别确定第一层数范围内的层数的第三数量,和/或,第二层数范围内的层数的第四数量,将第三数量和第四数量中的最大值,确定为用于指示层数的指示信息的比特宽度。
示例地,在本公开实施例中,以PUSCH传输支持的天线端口数量为8为例,在PUSCH的码字个数为1的情况下,指示信息指示的层数为层
数不大于4的层数,即码字个数为1的情况下,第一层数范围可以为层数1至层数4的层数范围;在PUSCH的码字个数为2的情况下,指示信息指示的层数为层数大于4的层数,即码字个数为2的情况下,第二层数范围可以为层数5至层数8的层数范围,具体可以根据实际需要进行设置,在此,本公开实施例只是以此为例进行说明,但并不代表本公开实施例仅局限于此。
需要说明的是,在该种可能的实现方式中,预设的映射关系的表达方式包括下述至少一种:
表格方式;
位图方式;
函数方式。
需要说明的是,当采用表格的方式表达时,其具体实现与上述当目标信息包括预编码矩阵时,采用表格的方式的具体实现类似,可参见上述相关描述,在此,本公开实施例不再进行赘述。
在又一种可能的实现方式中,PUSCH传输对应的目标信息包括预编码矩阵和层数。在根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的预编码矩阵和层数时,在码字个数为第一数量的情况下,在码字个数为第一数量的情况下,指示信息指示的预编码矩阵为第一层数范围内的层数对应的预编码矩阵,指示信息指示的层数为第一层数范围内的层数;在码字个数为第二数量的情况下,指示信息指示的预编码矩阵为第二层数范围内的层数对应的预编码矩阵,指示信息指示的层数为第二层数范围内的层数。
需要说明的是,在该种可能的实现方式中,基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的预编码矩阵,与上述可能的实现方式中,当目标信息包括预编码矩阵时,基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的预编码矩阵的实现方式类似,可参见上述相关描述,在此,本公开实施例不再进行赘述。
基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应
的层数,与上述可能的实现方式中,当目标信息包括层数时,基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的层数的实现方式类似,可参见上述相关描述,在此,本公开实施例不再进行赘述。
可以理解的是,当目标信息包括预编码矩阵和层数时,预编码矩阵和层数可以独立指示,也可以联合指示,具体可以根据实际需要进行设置。其中,独立指示可以理解为预编码矩阵和层数分别通过两个指示信息进行指示,即预编码矩阵和层数均对应有各自的指示信息,联合指示可以理解为编码矩阵和层数分别通过同一个指示信息进行指示,即编码矩阵和层数对应一个指示信息,基于该指示信息可以同时确定预编码矩阵和层数。
当目标信息包括预编码矩阵和层数独立指示时,示例地,在PUSCH的码字个数为1的情况下,用于指示预编码矩阵的指示信息指示的预编码矩阵为层数不大于4的层数,用于指示层数的指示信息指示的预编码矩阵为层数不大于4的层数对应的预编码矩阵;在PUSCH的码字个数为2的情况下,用于指示预编码矩阵的指示信息指示的预编码矩阵为层数大于4的层数,用于指示层数的指示信息指示的预编码矩阵为层数大于4的层数对应的预编码矩阵。
当目标信息包括预编码矩阵和层数联合指示时,示例地,在PUSCH的码字个数为1的情况下,指示信息指示的预编码矩阵为层数不大于4的层数,指示的预编码矩阵为层数不大于4的层数对应的预编码矩阵;在PUSCH的码字个数为2的情况下,指示信息指示的预编码矩阵为层数不大于4的层数,指示的预编码矩阵为层数不大于4的层数对应的预编码矩阵。
示例地,在另一种可能的场景中,即基于非码本的PUSCH传输场景。在基于非码本的PUSCH传输场景中,通常需要确定PUSCH传输对应的信道探测参考信号资源和层数,并基于信道探测参考信号资源进一步确定预编码矩阵,再基于PUSCH传输对应的预编码矩阵和/或层数,进行PUSCH传输。
需要说明的是,在该种场景中,确定PUSCH传输对应的层数的具体
实现,与上述基于码本的PUSCH传输场景中,确定PUSCH传输对应的层数的具体实现类似,可参见上述相关描述,在此,本公开实施例不再进行赘述。下面,将针对该种场景中,如何确定PUSCH传输对应的信道探测参考信号资源进行详细描述。
示例地,当PUSCH传输对应的目标信息包括探测参考信号资源时,根据基于码字个数、指示信息,以及预设的映射关系,确定第一传输对应的预编码矩阵时,在码字个数为第一数量的情况下,指示信息指示的信道探测参考信号资源的数量为第一范围内的一个取值;在码字个数为第二数量的情况下,指示信息指示的信道探测参考信号资源的数量为第一范围内的一个取值;其中,第一范围和第二范围不同,第五数量即为第一范围内的取值数量,第六数量即为第二范围内的取值数量。
示例地,在本公开实施例中,用于信道探测参考信号资源的指示信息的比特宽度是基于第一范围,和/或,第二范围确定的。
示例地,在基于第一范围和第二范围共同确定指示信息的比特宽度时,可以分别确定第一范围包括的取值的第五数量和第一范围包括的取值的第六数量,将该两个数量中的最大值,确定为用于指示预编码矩阵的指示信息的比特宽度。
示例地,在本公开实施例中,以PUSCH传输支持的天线端口数量为8为例,在PUSCH的码字个数为1的情况下,指示信息指示的信道探测参考信号资源为SRS资源数量不大于4的信道探测参考信号资源,即码字个数为1的情况下,第一范围可以SRS资源数量不大于4的范围;在PUSCH的码字个数为2的情况下,指示信息指示的信道探测参考信号资源为SRS资源个数均大于4的信道探测参考信号资源,即码字个数为2的情况下,第二范围为SRS资源数量大于4的范围,具体可以根据实际需要进行设置,在此,本公开实施例只是以此为例进行说明,但并不代表本公开实施例仅局限于此。
在该可能的场景中,以预设的映射关系包括表格方式为例,示例地,在根据基于码字个数、指示信息,以及预设的码本,确定第一传输对应的
信道探测参考信号资源时,可参见下述实施例4。
实施例4
步骤1、接收网络设备发送的PUSCH传输的调度消息;其中,调度消息包括PUSCH传输的参数信息和指示信息,参数信息用于确定码字个数,指示信息用于指示信道探测参考信号资源。
步骤2、在确定PUSCH的码字个数为1的情况下,基于指示信息和第四表格确定PUSCH传输对应的信道探测参考信号资源;在确定PUSCH的码字个数为2的情况下,基于指示信息和第五表格确定PUSCH传输对应的信道探测参考信号资源。
示例地,第四表格中任意一个entry指示的SRS资源数量不大于4,第五表格中任意一个entry指示的SRS资源数量均大于4。
在该可能的场景中,以预设的映射关系包括编码方式为例,示例地,在根据基于码字个数、指示信息,以及预设的码本,确定第一传输对应的信道探测参考信号资源时,可参见下述实施例5。
实施例5
步骤1、接收网络设备发送的PUSCH传输的调度消息;其中,调度消息包括PUSCH传输的参数信息和指示信息,参数信息用于确定码字个数,指示信息用于指示信道探测参考信号资源。
步骤2、在确定PUSCH的码字个数为1的情况下,基于指示信息和第四编码方式确定PUSCH传输对应的信道探测参考信号资源;在确定PUSCH的码字个数为2的情况下,基于指示信息和第五编码方式确定PUSCH传输对应的信道探测参考信号资源。
示例地,第四编码方式中任意一个指示信息指示的SRS资源数量不大于4,第五编码方式中任意一个指示信息指示的SRS资源数量均不大于4。
基于上述描述可以看出,在maxMIMOLayers大于4,且PUSCH的码字个数为2的情况下,基于第四表格确定PUSCH传输对应的SRS资源,和/或,基于第四编码方式确定PUSCH传输对应的SRS资源;PUSCH的码字个数为1的情况下,基于第五表格确定PUSCH传输对应的SRS资源,
和/或,基于第五编码方式确定PUSCH传输对应的SRS资源。
和/或,
在maxMIMOLayers小于或等于4时,基于第六表格确定PUSCH传输对应的SRS资源,和/或,基于第六编码方式确定PUSCH传输对应的SRS资源。
其中,第六表格中任意一个entry指示的SRS资源数量为1到maxMIMOLayers中的一项;第三编码方式中任意一个指示信息指示的SRS资源数量为1到maxMIMOLayers中的一项。
其中,maxMIMOLayers是基于层数限制信息确定的最大层数,或者,PUSCH可以被调度的最大MIMO层数,即网络设备配置的层数;或者,UE支持的PUSCH可以传输的最大MIMO层数,即终端支持的最大层数终端中至少一种确定的。
示例地,在本公开实施例中,用于调度PUSCH的DCI类型DCI format 0_1和DCI format 0_2可以对应同一个maxMIMOLayers参数。也可以对应不同的maxMIMOLayers参数,例如,一个用maxMIMOLayersDCI-0-1指示,一个用maxMIMOLayersDCI-0-2指示,具体可以根据实际需要进行设置,在此,本公开实施例不做具体限制。
上述各实施例中,PUSCH的调度信息可以指DCI,也可以是RRC信令配置的调度信息,即本公开实施例提供的信息确定方法既可以用于基于DCI调度的PUSCH传输,也可以用于基于配置的授权的PUSCH传输。
需要说明的是,针对基于非码本的PUSCH场景,SRS资源和层数可以独立指示,即预编码矩阵和层数均对应有各自的指示信息,SRS资源的数目等于层数。在PUSCH的码字个数为1的情况下,指示信息指示的信道探测参考信号资源为SRS资源数量不大于4的信道探测参考信号资源;在PUSCH的码字个数为2的情况下,指示信息指示的信道探测参考信号资源为SRS资源个数均大于4的信道探测参考信号资源。
在PUSCH的码字个数为1的情况下,指示信息指示的层数为层数不大于4的层数;在PUSCH的码字个数为2的情况下,指示信息指示的层
数为层数大于4的层数。
需要说明的是,上述实施例只是以PUSCH传输为例进行说明,在未来系统中,或许可以扩展至更多的上行传输,例如上行控制信道(Physical Uplink Control Channel,PUCCH)传输等,具体可以根据实际需要进行设置。

示例地,在目标信息包括信道探测参考信号资源时;在码字个数为第一数量的情况下,指示信息指示的信道探测参考信号资源的数量为第一范围内的一个取值。
在码字个数为第二数量的情况下,指示信息指示的信道探测参考信号资源的数量为第二范围内的一个取值;其中,第一范围和第二范围不同。
示例地,指示信息的比特宽度是基于第一范围,和/或,第二范围确定的。
示例地,指示信息的比特宽度是基于第一范围包括的取值的第五数量,和/或,第二范围包括的取值的第六数量确定的;其中,在指示信息的比特宽度是基于第五数量和第六数量确定的情况下,指示信息的比特宽度为第五数量和第六数量的最大值。
需要说明的是,在本公开实施例中,其具体实现可参见上述实施例中的相关描述,在此,本公开实施例不再进行赘述。
示例地,在本公开实施例中,网络设备向终端发送的相关信息时,例如,参数信息、指示信息等,可以通过无线资源控制(Radio Resource Control,RRC)信令、媒体接入控制的控制单元MAC-CE信令、DCI信令中的一项或多项进行指示,具体可以根据实际需要进行设置。
可以看出,本公开实施例中,网络设备通过确定第一传输对应的参数信息、和第一传输对应的目标信息对应的指示信息;其中,参数信息用于确定码字个数,目标信息包括预编码矩阵、层数或者信道探测参考信号资源中的至少一个,指示信息用于指示目标信息;并向终端发送参数信息和指示信息;使得终端基于参数信息和指示信息,确定第一传输对应的目标信息。这样结合用于确定第一传输的码字个数的参数信息共同确定第一传输对应的目标信息,可以有效地降低指示信息的开销,从而解决了随着天线端口数的增多,导致的用于指示预编码矩阵、层数或者信道探测参考信号资源的指示信息开销较大的问题,从而降低了指示信息开销。
