本申请实施例提供了一种无线通信方法,可用于确定发送SRS的时隙。
为便于对本申请实施例的理解,下面对SRS进行介绍。
探测参考信号(Sounding Reference Signal,SRS)信号是5G/NR系统中重要的参考信号,广泛用于NR系统中的各种功能中,例如,SRS可以用于以下场景:
1.用于下行信道状态信息的获取(UE sounding procedure for DL CSI acquisition)
2.用于上行传输的频域调度和预编码确定;
3.用于天线切换(Antenna Switching)功能;
4.用于载波切换(Carrier Switching)功能(UE sounding procedure between component carriers);
5.用于定位功能;
6.配合基于码本(codebook-based)的上行传输;
7.配合基于非码本(Non-Codebook based)的上行传输。
网络设备可以给一个终端设备配置一个或多个SRS资源组(SRS Resource set),每个SRS Resource set可以配置1个或多个SRS resource(SRS资源)。
SRS的传输可以分为周期性(Periodic)、半持续(Semi-persistent)、非周期(Aperiodic)。
周期SRS是指周期性传输的SRS,其周期和时隙偏移由RRC信令配置,终端设备一旦接收到相应的配置参数,就按照一定的周期发送SRS,直到所述RRC配置失效。周期性SRS的空间相关信息(Spatial Relation Info)也由RRC信令配置。所述空间相关信息可以指示一个信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),同步信号/物理广播信道块(Synchronization Signal/PBCH Block,SSB)或者参考SRS。例如,可以通过隐式的方式来指示周期SRS的发送波束。例如,终端设备根据指示的CSI-RS/SSB来确定周期SRS的发送波束。再如, 终端设备可以通过SRS资源的空间相关信息确定在SRS资源上传输SRS所用的发送波束。
半持续性SRS的周期和时隙偏移(slot offset)由RRC信令配置,但其激活和去激活信令是通过MAC CE承载的。终端设备在接收到激活信令后开始传输SRS,直到接收到去激活信令为止。半持续SRS的空间相关信息(发送波束)通过激活SRS的MAC CE一起承载。
终端设备接收到RRC配置的周期和时隙偏移后,根据以下公式确定能够用于传输SRS的时隙:

其中,T SRS和T offset为配置的周期和偏移,n f
Figure PCTCN2020117812-appb-000002
分别为无线帧和时隙编号。
非周期SRS传输指网络设备可以通过DCI触发终端设备的SRS传输。用于触发非周期SRS传输的触发信令既可以通过UE专属搜索空间或公共搜索空间(Common search space)中用于调度PUSCH/PDSCH的DCI承载,也可以通过公共搜索空间中的DCI format 2_3来承载。
其中,DCI format 2_3不仅可以用于触发非周期SRS传输,也可以同时用于配置一组UE或一组载波上的SRS的功率控制指令(TPC)命令。
表1 SRS触发信令

例如,若DCI中的SRS请求域的值为11,则SRS的触发信令指示使用更高层参数非周期SRS资源触发(aperiodicSRS-ResourceTrigger)设置为3的SRS资源组进行SRS传输。
终端设备接收到非周期SRS触发信令(例如DCI)后,在触发信令所指示的非周期SRS资源组上进行SRS传输。其中,触发信令与SRS传输之间的时隙偏移(slot offset)可以由高层信令(RRC)配置。网络设备预先通过高层信令指示终端设备每个SRS资源组的配置参数,包括时频资源、序列参数、功率控制参数等。另外,对于触发的SRS资源组中的每个SRS资源,终端设备还可以通过该资源的空间相关信息确定在该资源上传输SRS所用的发送波束,该空间相关信息可通过RRC配置给每个SRS资源。
在新空口(New Radio,NR)系统中,为了支持各种可能的部署场景,以及未来各种新型业务类型,系统设计非常灵活,例如,上下行的资源可以通过高层信令以及物理层信令来指示和调整。因此,针对一个时隙(slot)或一个slot上的某些符号在不同的时刻可能可以用于不同方向的传输,例如,某个时刻可以用于上行传输,某个时刻用于下行传输。
但是,如前所述,针对非周期探测参考信号(Sounding Reference Signal,SRS),其时隙偏移(slot offset)可以由高层信令配置,相当于,在RRC信令重新配置其他取值之前,每次触发信令与SRS传输之间的时隙偏移是不变的,导致用于接收触发信令的时隙和用于发送SRS的时隙相对位置是固定的,增加了限制性并降低了系统灵活性。
例如,假设时隙偏移为k,如果要触发SRS在slot n+k上传输,那么对应的触发信令只能在slot n上发送,这就限制了发送触发信令的时机,给网络设备的调度工作增加了额外不必要的限制。
再如,当某个slot,或者某个slot上某些符号被动态地从可以上行传输变成下行传输时,可能会使得某次非周期SRS无法传输。例如,若slot n+k被更改为用于下行传输,则在slot n上发送的触发SRS信令是无效的,或者不能在slot n上发送触发信令。
在本申请的一些实施例中,若网络设备在slot n上发送SRS触发信令,则终端设备可以在slot n+k或之后的第一个有效slot上传输SRS。通过在slot n+k或之后的第一个有效slot上传输SRS,虽然可以提高传输SRS的成功率,但效率不高,还会增加网络设备的配置和调度复杂度,主要原因在于有效slot不是固定的,需要根据相关配置或因素(例如上下行时隙配置和/或指示)来确定。
进一步的,本申请实施例提供了一种无线通信方法,。
需要说明的是,本申请实施例中,将能够或可用于传输SRS的时隙称为有效时隙(valid slot)。
图2示出了根据本申请实施例的无线通信方法200的示意性流程图,所述方法200可以由终端设备和网络设备交互执行。图2中所示的终端设备可以是如图1所示的终端设备,图2中所示的网络设备可以是如图1所示的接入网设备。

S210,接收第一指示信息;

例如,所述终端设备根据所述第一指示信息确定至少一个小区组中的目标小区组。
通过所述第一指示信息,使得第一小区上的非周期SRS触发信令,可触发终端设备在目标小区组中的活跃小区上的SRS传输,换言之,能够实现针对多小区场景下的跨小区(或跨载波)或多小区(或多载波)的非周期SRS的触发传输。
此外,避免了为每个小区仅通过自己接收的非周期SRS触发信令触发SRS,不仅能够提高触发信令的灵活性,还能够降低非周期SRS触发信令(DCI)的资源消耗。
在本申请的一些实施例中,所述第一指示信息通过所述非周期SRS触发信令中的第一触发状态指示所述目标小区组。
在本申请的一些实施例中,所述非周期探测参考信号SRS触发信令可以通过下行控制信息DCI格式0_1、或DCI格式0_2、DCI格式1_1、或DCI格式1_2之一进行传输,或者,也可以通过进行DCI格式2_3传输。

SRS资源指示(SRS resource indicator)域;
预编码信息和层数(Precoding information and number of layers)域;或
天线端口类型(Antenna ports)域。
例如,载波指示域的bit数目可以是3,相当于,所述目标小区组可以最多可以是8个小区组中的小区组,在复杂度和灵活性之间比较好的折中。时域资源分配域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。频域资源分配域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。调制编码方案域的bit数目固定,最大支持的组也固定,可以降低终端和网络复杂度。HARQ进程号域的bit数目固定,最大支持的组也固定,可以降低终端和网络复杂度。用于预定的PUSCH的发射功率控制TPC命令域的bit数目固定,最大支持的组也固定,可以降低终端和网络复杂度。SRS资源指示域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。预编码信息和层数域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。天线端口类型域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。
此外,通过第一域中的部分或全部比特位承载所述第一指示信息,相当于,复用所述第一域的比特承载所述第一指示信息,能够降低信令开销。
在本申请的一些实施例中,所述同一信令为下行控制信息DCI格式0_1或DCI格式0_2。
在本申请的一些实施例中,所述第一域为所述第一指示信息专用的域。
换言之,所述第一域中的比特专门用于承载所述第一指示信息。
在本申请的一些实施例中,所述同一信令为下行控制信息DCI格式0_1、或DCI格式0_2、DCI格式1_1、或DCI格式1_2。

如图3所示,所述MAC CE信令可包括服务小区标识(Serving Cell ID)和T个小区组的位图,其中,所述MAC CE信令中针对每个小区组的位图的长度为8。即,所述MAC CE信令中针对每个小区组的位图为C 0~C 7。如果所述终端配置的小区少于8个,则位图中部分比特不起作用,或者终端可以忽略位图中部分比特,或者位图中部分比特可以为预留比特。换言之,若前述MAC CE信令中的可用于位图的比特位的数量为X,且实际ServCellIndex最大值小于X,则X个比特位中的部分比特位可作为保留比特位。可选的,所述保留比特位可不用于实际用途。换言之,所述X个比特位可以包括所述用于指示所述第一小区组的除位图之外的保留比特位。所述保留比特位也可称为剩余的比特位。应理解,其他实施例中类似处理,为避免重复,不再一一赘述。
服务小区标识可以是上文所述的第一小区的标识。
换言之,服务小区标识可用于指示上文所述的MAC CE用于哪个小区(indicates the identity of the Serving Cell for which the MAC CE applies)。例如,所述服务小区标识可占用5bit。
例如,C 0~C 7分别为上文所述的至少一个小区组中每一个小区组中的小区的标识对应的bit。
换言之,C 0~C 7分别对应8个小区。例如,C 0~C 7中的C i对应服务小区索引(ServCellIndex)为i的小区,如果C i的取值为1,表示ServCellIndex为i的小区属于对应的小区组;如果C i的取值为0,表示ServCellIndex为i的小区不属于对应的小区组。当然,在其他可替代实施例中,如果C i的取值为0,表示ServCellIndex为i的小区属于对应的小区组;如果C i的取值为1,表示ServCellIndex为i的小区不属于对应的小区组。
需要说明的是,本申请对未标注或者说明的bit不限制具体用途。例如,可以用于指示,也可用于Reserved bit。
例如,未标注或者说明的bit可以是R,R表示预留比特(reseved bit),例如,其取值可为0。

即,所述MAC CE信令中针对每个小区组的位图为C 0~C 31
应理解,图3至图7仅为本申请的示例,不应理解为对本申请的限制。
例如,在其他可替代实施例中,所述MAC CE信令中针对每个小区组的位图,可从由左向右的排列顺序,变更为由右向左的排列顺序。换言之,只要保证终端设备和网络设备对每一个小区组中小区的排列顺序理解一致,本申请对所述每一个小区组中小区的排列顺序不作具体限定。
再如,在其他可替代实施例中,所述MAC CE信令还可以包括其他信息。再如,在其他可替代的实施例中,所述MAC CE信令中的各个信息的位置可以更换,例如R可以放在第一行的末尾,也可以放在第一行的前面。
此外,可以基于终端设备配置的服务小区索引(ServCellIndex)的最大值确定所述MAC CE信令的格式。
例如,网络设备可以通过RRC信令确定或者切换所述至少一个比特位的长度,即确定或切换所述MAC CE信令的格式。例如,若所述终端设备配置的ServCellIndex的最大值小于8,可以使用位图的长度为8bit的MAC CE;若所述终端设备配置的ServCellIndex的最大值大于等于8,且小于16,可以使用位图的长度为16bit的MAC CE;若所述终端设备配置的ServCellIndex的最大值大于等于16,且小于24,可以使用位图的长度为24bit的MAC CE;若所述终端设备配置的ServCellIndex的最大值大于等于24,可以使用位图的长度为32bit的MAC CE。
当然,也可以将可位图的长度的划分粒度也可以大于8。
例如,若所述终端设备配置的ServCellIndex的最大值大于等于8,且小于32,可以使用位图的长度为16bit或32bit的MAC CE。

换言之,所述X 1_2,X 1_1,X 1_0~X T_2,X T_1,X T_0可以用于承载上文所述的第二信息。
或者说,可以将MAC CE信令中的第三信息替换为第二信息。

实施例1:
本实施例中,所述第三指示信息是针对所述第一小区或所述第一BWP配置的。
步骤1:
终端设备接收网络设备通过RRC信令发送的小区配置信息。
例如,小区聚合(Carrier Aggregation,CA)配置信息。其中配置有A个小区。针对A个小区中的1个或多个(记为B,B<=A)中的每一个小区(部分情况下,可能有的小区不配置对应的非周期SRS,因此写成A中的1个或多个),网络设备通过RRC信令携带SRS配置信息,配置1个或多个SRS资源组,每个SRS资源组包含1个或多个SRS资源。下面描述是针对B个小区中的某个小区进行描述,不同小区上的配置可以独立。下面以小区Z为例来描述。
可选的,小区Z上所述SRS资源组通过RRC信令SRS-ResourceSet配置,所述SRS资源通过RRC信令SRS-Resource配置。

可选的,所述RRC信令通过SRS-Config配置。

可选的,第一信令通过DCI Format 0_1,或DCI Format 0_2指示。

例如,载波指示域的bit数目可以是3,相当于,所述目标小区组可以最多可以是8个小区组中的小区组,在复杂度和灵活性之间比较好的折中。时域资源分配域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。频域资源分配域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。调制编码方案域的bit数目固定,最大支持的组也固定,可以降低终端和网络复杂度。HARQ进程号域的bit数目固定,最大支持的组也固定,可以降低终端和网络复杂度。用于预定的PUSCH的发射功率控制TPC命令域的bit数目固定,最大支持的组也固定,可以降低终端和网络复杂度。SRS资源指示域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。预编码信息和层数域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。天线端口类型域的bit数目可以较多,相当于,可以更灵活的指示所述目标小区组。

可选的,所述第一域是一个新增的域,其是否存在,根据网络RRC信令确定。
可选的,所述第一信令通过DCI Format 0_1,或DCI Format 0_2,或者DCI Format 1_1,或DCI Format 1_2指示。
步骤3:
终端设备根据第一信令可以在1个或多个小区上发送非周期SRS。
选项1:
终端设备根据第一信令可以在小区组t中的1个或多个小区中的活跃小区上发送对应的非周期SRS,其中任意活跃小区记为Z’。可以实现只触发其他小区的非周期SRS传输,这可以为网络提供更大的灵活性。
选项2:
终端设备根据第一信令可以在小区Z,以及小区组t中的1个或多个小区中的活跃小区上发送对应的非周期SRS,其中任意活跃小区记为Z’,可以包括小区Z在内。和选项1相比,可以减少RRC或者MAC CE指示T个小区组时的信令开销。
针对上述确定的小区中的每一个小区Z’,发送第一信令取值value对应的SRS资源组对应的非周期SRS,由于在Z’上的非周期SRS资源组里面配置有触发状态,因此每个Z’上会有和第一信令取值value对应的非周期SRS资源组。对应的SRS资源组配置有1个时隙偏移(slot offset)或多个时隙偏移。

可选的,若第一信令中UL-SCH indicator取值为0,所述第一域可以使用DCI以下域中的全部或者部分bit来指示相关信息:
载波指示(Carrier indicator)域;

可选的,所述第一域与非周期SRS触发信令在同一个DCI信令中(第一信令)。
可选的,所述第一域是一个新增的域,其是否存在,有网络RRC信令配置。
可选的,所述第一信令通过DCI Format 0_1,或DCI Format 0_2,或者DCI Format 1_1,或DCI Format 1_2指示。
步骤3:应理解,实施例3中的步骤3可参考实施例1中的步骤3,为避免重复,此处不再赘述。
上面结合实施例1至实施例3对第一指示信息用于触发SRS资源组对应的SRS的方案进行了说明,下面结合实施例4至实施例6对所述第一指示信息用于触发SRS资源对应的SRS进行说明。
实施例4:
本实施例中,所述第三指示信息是针对所述第一小区或所述第一BWP配置的。
步骤1:
终端设备接收网络设备通过RRC信令发送的小区配置信息。
例如,小区聚合(Carrier Aggregation,CA)配置信息。其中配置有A个小区。针对A个小区中的1个或多个(记为B,B<=A)中的每一个小区(部分情况下,可能有的小区不配置对应的非周期SRS,因此写成A中的1个或多个),网络设备通过RRC信令携带SRS配置信息,配置1个或多个SRS资源组,每个SRS资源组包含1个或多个SRS资源。下面描述是针对B个小区中的某个小区进行描述,不同小区上的配置可以独立。下面以小区Z为例来描述。
可选的,所述SRS资源组通过RRC信令SRS-PosResourceSet-r16配置,所述SRS资源通过RRC信令SRS-PosResource-r16配置。
可选的,针对至少一个所述SRS资源组(记为Set X)配置有多个(记为M个,M>=1)触发状态。可选的,每个触发状态对应非周期SRS触发信令中SRS请求域的一个取值,即一个码点(code point)。例如表1的触发状态的取值。
可选的,多个触发状态通过SRS-PosResourceSet-r16中的aperiodicSRS-ResourceTriggerList-r16来配置。
可选的,aperiodicSRS-ResourceTriggerList-r16中每个元素的取值为1到N-1的一个整数。
例如,N可以等于非周期SRS触发状态数目(maxNrofSRS-TriggerStates),取值为4。
再如,根据网络设备发送的配置信息确定N的取值为4或更大值(例如,8或16);当然,在其他可替代实施例中,可采用其他命名。通过增加非周期SRS触发信令所对应的状态数,可以提高DCI触发非周期SRS的灵活性,提高系统性能,从而可以实现跨小区触发非周期SRS,降低DCI开销,增加系统灵活性。
可选的,所述配置信息通过RRC信令,或者MAC CE信令指示终端设备。
可选的,终端设备通过终端设备能力上报信息通知网络设备可以支持更多的非周期SRS触发状态(Maximum number of SRS trigger states),即N大于4,以便网络设备基于终端设备上报的能力确定N。
可选的,所述RRC信令通过SRS-Config配置
步骤2:应理解,实施例4中的步骤2可参见实施例1中的步骤2,为避免重复,此处不再赘述。
步骤3:
终端设备在小区Z上接收到非周期SRS触发信令(记为第一信令),所述第一信令对应的触发状态大于0(其取值记为value,简称为第一取值),即非零触发状态,则在前述确定的小区上发送对应的非周期SRS。
针对上述确定的小区中的每一个小区上(记为Z’),可以包括小区Z在内,发送第一信令取值value对应的SRS资源组对应的非周期SRS,由于在Z’上的非周期SRS资源组里面配置有触发状态,因此每个Z’上会有和第一信令取值value对应的非周期SRS资源组。对应的SRS资源配置有1个时隙偏移(slot offset)或多个时隙偏移
可选的,终端设备在小区Z的时隙slot n上接收到非周期SRS触发信令(例如DCI),终端设备根据SRS资源对应的时隙偏移确定小区Z’对应的slot n’上传输SRS资源。
可选的,根据SRS资源对应的时隙偏移k(在SRS资源配置1个时隙偏移的情况下,或在激活了一个时隙偏移的情况下),或者MAC信令激活的SRS资源对应的时隙偏移k(在SRS资源配置有1个或多个时隙偏移的情况下),或者非周期SRS触发信令指示的SRS资源对应的时隙偏移k(在SRS资源配置多个时隙偏移的情况下),确定的SRS的发送slot,即slot n’。
例如,可参见实施例1中涉及的公式确定所述slot n’。
可选的,根据SRS资源对应的时隙偏移k(在SRS资源配置1个时隙偏移的情况下,或在激活了一个时隙偏移的情况下),或者MAC信令激活的SRS资源对应的时隙偏移k(在SRS资源配置有1个或多个时隙偏移的情况下),或者非周期SRS触发信令指示的SRS资源对应的时隙偏移k(在SRS资源配置多个时隙偏移的情况下),非周期SRS触发信令所在时隙之后的在小区Z’上的第k个或者第k+1个有效时隙为slot n’。由此,可以更灵活地触发非周期SRS,减少响应非周期SRS触发信令拥挤概率。可选的,所述有效时隙为可以传输所述SRS的时隙。
实施例5:
本实施例中,所述第三指示信息是针对非周期SRS触发状态配置的。
步骤1:终端设备接收网络设备通过RRC信令发送的小区配置信息。
应理解,实施例5中的步骤1可参考实施例4中的步骤1,为避免重复,此处不再赘述。
步骤2:应理解,实施例5中的步骤2可参见实施例2中的步骤2,为避免重复,此处不再赘述。
步骤3:应理解,实施例5中的步骤3可参见实施例4中的步骤3,为避免重复,此处不再赘述。
实施例6:

步骤1:终端设备接收网络设备通过RRC信令发送的小区配置信息。
应理解,实施例5中的步骤1可参考实施例3中的步骤1,为避免重复,此处不再赘述。
步骤2:应理解,实施例6中的步骤2可参见实施例3中的步骤2,为避免重复,此处不再赘述。
步骤3:应理解,实施例6中的步骤3可参见实施例4中的步骤3,为避免重复,此处不再赘述。
