Description

一种通信方法、装置及计算机可读存储介质 技术领域
本申请涉及无线通信技术领域,具体涉及一种通信方法、装置及计算机可读存储介质。
背景技术
通信系统中可通过参考信号获得信道的信道状态信息,网络设备能够基于信道状态信息,选择更加合适的调制编码方式以及预编码等信息。例如,网络设备可通过接收终端发送的探测参考信号(sounding reference signal,SRS),获得信道状态信息。其中,SRS可以是非周期性的参考信号。网络设备会为终端设备配置SRS资源集合,还会通过高层信令给每个SRS资源集合配置有效时序偏移值列表,该列表包括多个有效时序偏移值,再通过下行控制信息(downlink control information,DCI)信令指示该有效的时序偏移列表中的一个有效时序偏移值t,该DCI还用于触发非周期的SRS的发送。
当网络设备通过DCI触发SRS的发送时,终端设备可基于DCI信令指示的有效时序偏移值t,在以参考时隙起始的第t+1个有效的时隙发送该非周期的SRS。
然而,通常为了减少DCI开销,提高覆盖,DCI信令可能并不存在指示有效时序偏移值的字域,此时终端设备将无法确定在哪个时隙上发送SRS,以致降低了传输效率。
发明内容
本申请提供了一种通信方法、装置及计算机可读存储介质,可以在DCI信令中不存在用于指示有效时序偏移值的字域时,确定发送SRS的时隙,提高传输效率。
第一方面,本申请提供了一种通信方法。该通信方法可以用于在DCI信令中不存在字域指示有效时序偏移值时,确定发送SRS的时隙。一种情况下,该通信方法可以应用于终端设备,也可以应用于终端设备侧的各种形态的装置/设备(例如,芯片)。另一种情况下,该通信方法可以应用于网络设备,也可以应用于网络设备侧的各种形态的装置/设备(例如,芯片)。下面以应用于终端设备为例进行描述。通信方法可以包括:在第一时间单元上接收第一指示信息,第一指示信息用于触发第一参考信号资源集合;当第一指示信息中不包括第一字域时,确定第一参考信号资源集合的目标有效时序偏移值,第一字域用于指示第一参考信号资源集合的目标有效时序偏移值;根据第一参考信号资源集合的目标有效时序偏移值,在第二时间单元上的第一参考信号资源集合上发送第一参考信号资源集合对应的参考信号。
在本申请提供的方案中,通常网络设备会向终端设备发送指示第一参考信号资源集合对应的有效时序偏移值列表的指示信息,以及用于触发第一参考信号资源集合的指示信息,用于触发第一参考信号资源集合的指示信息中携带有第一字域,第一字域指示第一参考信号资源集合对应的有效时序偏移值列表中的一个有效时序偏移值。终端设备将第一字域中指示的有效时序偏移值确定为第一参考信号资源集合的目标有效时序偏移值。如果接收到用于触发第一参考信号资源集合的指示信息中,不存在指示有效时序偏移值的字域时,本申请的技术方案,终端设备可以根据预设规则确定发送第一参考信号资源集合对应的参考 信号的时间单元。从而可以解决现有技术中的,当不存在指示有效时序偏移值的字域时,终端设备无法确定在哪个时隙上发送第一参考信号资源集合对应的参考信号的问题,进而提高了传输效率。
有效时序偏移值,可以理解为,是用于指示有效时间单元中的时序偏移。例如,有效时序偏移值为t,该指示有效时间单元中的第t+1个时间单元或者第t个时间单元。其中,有效时间单元是指可以用于发送参考信号的时间单元。具体地,有效时间单元可以是满足以下一个或多个条件的时间单元:时间单元为灵活时间单元和/或上行时间单元;时间单元中参考信号占用的时域资源与触发该参考信号资源集合的DCI占用的时域资源之间的时域资源偏移,大于或等于参考信号的处理时延;时间单元中允许用于发送参考信号的时域资源的数量大于或等于参考信号占用的时域资源的数量。又例如,有效时间单元是指不包括下行时间单元的可以用于传输参考信号的时间单元。又例如,有效时间单元可以是通过高层信令(如RRC或MAC CE信令)指示的时间单元。有效时间单元还可以有其它的定义方式,本申请不作限定。
在一种可能的实现方式中,该通信方法还包括:接收第二指示信息,第二指示信息用于指示第一参考信号资源集合对应的有效时序偏移值列表;第一参考信号资源集合包括一个参考信号资源集合,确定第一参考信号资源集合的目标有效时序偏移值包括:将第一参考信号资源集合对应的有效时序偏移值列表中的第一个有效时序偏移值确定为第一参考信号资源集合的目标有效时序偏移值。

在本申请提供的方案中,当第一参考信号资源集合包括一个参考信号资源集合时,第三时间单元可以是第一参考信号资源集合的参考时间单元。第三时间单元可以等于第一时间单元,即第三时间单元为接收第一指示信息的时间单元;也可以通过高层信令配置,即高层信令直接指示第三时间单元是哪个时间单元,或者指示第一参考信号资源集合的参考时序偏移值,从而可以更加灵活地指示第二时间单元。

具体实施方式
为了便于理解本申请,首先在此介绍本申请实施例涉及的相关术语。
1、PDCCH
为了提高终端设备盲检控制信道的效率,NR标准制定过程中提出了控制资源集合的概念。网络设备可为终端设备配置一个或多个资源集合,用于发送物理下行控制信道(physical downlink control channel,PDCCH)。网络设备可以在终端设备对应的任一控制资源集合上, 向终端设备发送控制信道。此外,网络设备还需要通知终端设备所述控制资源集合的相关联的其他配置,例如搜索空间集合等。每个控制资源集合的配置信息存在差异,例如频域宽度差异、时域长度差异等。可扩展地,本申请中的控制资源集合可以是5G移动通信系统定义的CORESET或控制区域(control region)或增强物理下行控制信道(enhanced-physical downlink control channel,ePDCCH)集合(set)。
PDCCH所占用的时频位置可以称之为下行控制区域。在LTE中,PDCCH始终位于一个子帧的前m个(m可能的取值为1、2、3和4)符号。应注意,LTE中E-PDCCH和R-PDCCH的位置未处于前m个符号。
在NR中,下行控制区域可以由无线资源控制(radio resource control,RRC)信令通过控制资源集合(control resource set,CORESET)和搜索空间集合(search space set)灵活配置:
控制资源集合可以配置PDCCH或控制信道单元(control channel element,CCE)的频域位置,时域的持续符号数等信息;
搜索空间集合可配置PDCCH的检测周期以及偏移量,在一个时隙内的起始符号等信息。
例如,搜索空间集合可配置PDCCH周期为1个时隙,而时域起始符号为符号0,则终端设备可以在每个时隙的起始位置检测PDCCH。
PDCCH用于传输DCI。不同内容的DCI采用不同的RNTI来进行CRC加扰,UE通过盲检RNTI可以得知当前的PDCCH的功能。
2、天线端口(antenna port)
天线端口也可以简称端口。被接收端设备所识别的发射天线,或者在空间上可以区分的发射天线。针对每个虚拟天线可以配置一个天线端口,每个虚拟天线可以为多个物理天线的加权组合,每个天线端口可以与一个参考信号端口对应。
3、带宽区域(bandwidth part,BWP)
网络设备可为终端设备配置一个或多个下行/上行带宽区域,该BWP可以是由频域上连续的PRB组成,BWP为终端设备带宽内的一个子集。该BWP在频域上的最小粒度是1个PRB。系统可为终端设备配置一个或多个带宽区域,且所述多个带宽区域在频域上可以重叠(overlap)。
在单载波场景下,一个终端设备在同一时刻可以只有一个激活的BWP,终端设备只能在激活的BWP(active BWP)上接收数据/参考信号,或者发送数据/参考信号。
在本申请中,适用于BWP场景的情况中,特定的BWP也可以是一个特定的频率上的带宽集合,或者是多个RB组成的集合。
4、单元载波(component carrier,CC)
单元载波又可以称为分量载波,组成载波,或成员载波等。多载波聚合中的每个载波都可以称为“CC”。终端设备可以在多个CC上接收数据。每个载波由一个或多个物理资源块(physical resource block,PRB)组成,每个载波上可以有各自对应的PDCCH,调度各自CC的PDSCH;或者,有些载波没有PDCCH,此时所述载波可以进行跨载波调度(cross-carrier scheduling)。
跨载波调度:网络设备在一个CC上发送PDCCH来调度另一个CC上的数据传输,即,在另一个CC上传输PDSCH,或者,在另一个CC上传输PUSCH。更具体地,网络设备可以在一个CC的带宽部分(BWP)上发送PDCCH来调度另一个CC上的BWP的PDSCH或PUSCH的传输。即,控制信道在一个CC上传输,而对应的数据信道在另一个CC上传输。
还应理解,本申请实施例中,“载波”可以理解为“服务小区”、“小区”。
可选地,小区包括下行载波、上行(uplink,UL)载波、上行补充(supplementary uplink,SUL)载波中的至少一个。具体地,小区可以包括下行载波、上行载波;或者小区可以包括下行载波、上行补充载波;或者小区包括下行载波、上行载波、上行补充载波。
可选地,上行补充载波的载频低于上行载波,用以提高上行覆盖。
可选地,一般情况下,FDD系统中,上行载波与下行载波的载频不同;TDD系统中,上行载波与下行载波的载频相同。
还应理解,本申请实施例中,上行资源在上行载波上;下行资源在下行载波上。
还应理解,本申请实施例中,上行载波可以是正常的上行载波,还可以是补充上行(supplementary uplink,SUL)载波。
5、时间单元、上行时间单元、下行时间单元以及灵活时间单元
时间单元是,例如但不限于,一个或多个无线帧,或是一个或多个子帧,或是一个或多个时隙,或是一个或多个微时隙(mini slot),或是一个或多个次时隙(sub slot),或是一个或多个符号,或者是多个帧或子帧构成的时间窗口,例如系统信息(system information,SI)窗口。一个符号的时间长度不做限制。针对不同的子载波间隔,一个符号的长度可以有所不同。
时域资源是,例如但不限于,一个或多个ofdm符号。例如,RS占用的时域资源可以通过网络设备配置的起始符号(或起始位置)和符号数量指示。
符号包括上行符号和下行符号,其中,上行符号可以称为单载波频分多址(single carrier-frequency division multiple access,SC-FDMA)符号或正交频分多址(orthogonal frequency division multiplexing,OFDM)符号;下行符号可以为OFDM符号。
通信系统基于上下行时间单元配比,将时域上的各时间单元划分为上行时间单元、下行时间单元、或灵活时间单元中的至少一种。
上行时间单元为包括的时域资源为用于上行传输的时间单元。下行时间单元为包括的时域资源为用于下行传输的时间单元。
灵活时间单元为包括灵活传输的时域资源的时间单元。灵活时间单元,可通过RRC信令指示该灵活传输的时域资源为上行传输的时域资源,或者下行传输的时域资源;或者,根据业务需求动态的指示该灵活传输的时域资源为上行传输的时域资源或下行传输的时域资源。例如,通过DCI信令指示该灵活传输的时域资源为上行传输的时域资源或下行传输的时域资源。可以理解的,灵活时间单元中灵活传输的时域资源还可作为保护间隔,从而利用预留的保护间隔避免上下行传输转换所带来的干扰。可以理解的,本申请各实施例中,灵活传输符号也可称为灵活符号(flexible symbol)。还可以理解的,本申请各实施例中,“灵活传输的时域资源”可以替换为“灵活符号”。例如,灵活时间单元为一个时隙,一个灵活传 输的时域资源为一个符号。
应理解,上述各个术语的定义可以参考现有技术(如3GPP协议38.214,38.213,38.212,38.211等)。但随着技术的不断发展,上述定义也有可能发生变化,本申请各实施例不作限制。
通信系统中可通过参考信号获得信道的信道状态信息,网络设备能够基于信道状态信息,选择更加合适的调制编码方式以及预编码等信息。例如,网络设备可通过接收终端设备发送的探测参考信号(sounding reference signal,SRS),获得信道状态信息。其中,SRS可以是非周期性的参考信号。网络设备会为终端设备配置SRS资源集合;当网络设备通过下行控制信息(downlink control information,DCI)触发SRS时,终端设备可基于SRS资源集合中的时序偏移(slot offset)的取值X,在该DCI所在的时间单元之后的时序偏移为X的时间单元上发送该SRS。例如,请参阅图1,图1是现有技术中的一种非周期SRS的发送示意图。如图1所示,假设SRS资源集合中配置的X=6,当网络设备需要终端设备在slot 8上发送SRS时,就需要严格提前在slot(8减6),即slot 2上发送DCI,以触发终端设备在slot 8上发送SRS。
现有技术中,网络设备通过RRC信令给每个SRS资源集合配置有效的时隙偏移列表,该列表中包括多个有效的时隙偏移值。网络设备再通过DCI信令指示该有效的时隙偏移列表中的一个时隙偏移值t,该DCI还触发非周期的SRS的发送。那么在以参考时隙起始的第t+1个有效的时隙发送该非周期的SRS。其中,参考时隙可以是上述DCI所在的时隙,或者参考时隙是由RRC信令指示的。其中,有效的时隙可以是满足以下一个或多个条件的时隙:
时隙为灵活时隙和/或上行时隙;
时隙中SRS占用的时域资源与触发该SRS的DCI占用的时域资源之间的时域资源偏移,大于或等于SRS的处理时延;
时隙中允许用于发送SRS的时域资源的数量大于或等于SRS占用的时域资源的数量。
该方案的技术缺陷,主要包括以下几个方面:
1、为减少DCI开销,提高覆盖,DCI信令可能并不存在字域指示有效的时隙偏移,此时很难确定在哪个时隙上发送SRS。
2、当一个DCI同时触发多个SRS资源集合时,很难确定在哪个时隙上发送SRS。
3、通过DCI指示每个非周期SRS资源集合的有效的时隙时,都要通过有效的时隙的定义先确定参考时隙后确定哪些时隙是有效的时隙,再在该有效的时隙中确定DCI指示的第t+1个有效的时隙,最终在该第t+1个有效的时隙上发送上述SRS。这种SRS的指示方式,使得终端设备和网络设备的实现复杂度较高。
因此,本申请实施例所要解决的技术问题可以包括如下:
1、当触发SRS资源的DCI中不存在字域用于指示该SRS资源的时隙信息时,终端设备可以通过定义默认的时隙偏移确定发送SRS的时隙;2、当一个DCI同时触发多个SRS资源集合时,特别是DCI同时触发多个用于天线切换的SRS资源集合(如1T4R,2T8R等)或者多个TRP对应的SRS资源集合时,通过本技术方案,可以确定在哪个时隙上发送SRS, 从而有效避免由于终端设备能力无法同时发送多个SRS资源集合(resource set)带来的资源集合丢弃的问题;3、通过使用本申请中的SRS的时隙的指示方法,可以有效降低终端设备和网络设备实现的复杂度。

501、网络设备在第一时间单元上向终端设备发送用于触发第一参考信号资源集合的第一指示信息。
相应地,终端设备在第一时间单元上接收来自网络设备的用于触发第一参考信号资源集合的第一指示信息。
其中,第一参考信号可以包括SRS、解调参考信号(demodulation reference signal,DMRS)等。第一参考信号资源集合可以是一个或多个参考信号资源集合,一个参考信号资源集合可以对应一个或多个参考信号,参考信号可以为非周期参考信号。第一指示信息可以是DCI。
可选地,网络设备向终端设备发送第二指示信息,该第二指示信息指示第一参考信号资源集合对应的有效时序偏移值列表。该第二指示信息可以是RRC,也可以是媒体接入控制控制元素(media access control control element,MAC CE)。
可选地,第二指示信息通常会给每个参考信号资源集合(resource set)指示一个有效时序偏移值列表,该列表包括一个或多个有效时序偏移值。
可选地,如果是下行,第一参考信号还可以包括信道状态信息参考信号(channel state information reference signal,CSI-RS)。例如,网络设备向终端设备发送第二指示信息和参考信号,终端设备可以根据第二指示信息确定第二时间单元,在第二时间单元接收网络设备发送的参考信号。
有效时序偏移值,可以理解为,是用于指示有效时间单元中的时序偏移。例如,有效时序偏移值为t,该指示有效时间单元中的第t+1个时间单元或者第t个时间单元。其中,有效时间单元是指可以用于发送参考信号的时间单元。具体地,有效时间单元可以是满足以下一个或多个条件的时间单元:时间单元为灵活时间单元和/或上行时间单元;时间单元中参考信号占用的时域资源与触发该参考信号资源集合的DCI占用的时域资源之间的时域资源偏移,大于或等于参考信号的处理时延;时间单元中允许用于发送参考信号的时域资源的数量大于或等于参考信号占用的时域资源的数量。又例如,有效时间单元是指不包括下行时间单元的可以用于传输参考信号的时间单元。又例如,有效时间单元可以是通过高层信令(如RRC或MAC CE信令)指示的时间单元。有效时间单元还可以有其它的定义方式,本申请不作限定。
502、当第一指示信息中不包括用于指示第一参考信号资源集合的目标有效时序偏移值的第一字域时,终端设备确定第一参考信号资源集合的目标有效时序偏移值。
可以理解,字域(filed)也可以称为字段,本申请对此不作限定。
通常,网络设备会向终端设备发送第二指示信息,第二指示信息指示第一参考信号资源集合对应的有效时序偏移值的列表,再发送第一指示信息触发该第一参考信号资源集合,第一指示信息包括第一字域,第一字域指示该列表中的一个有效时序偏移值,则终端设备可以将第一字域指示的这个有效时序偏移值确定为第一参考信号资源集合的目标有效时序偏移值。
在一种实现方式中,第一指示信息是否包括第一字域可以取决于第一指示信息的格式。
在另一种实现方式中,第一指示信息是否包括第一字域可以取决于第一指示信息的格式和高层信令。如第一格式的第一指示信息中是否存在第一字域,由高层信令配置。高层信令可以是RRC信令,也可以是MAC CE,还可以是其它能够实现配置第一指示信息中是否存在第一字域,这一功能的其它信令。
在又一种实现方式中,第一指示信息中是否包括第一字域取决于第一指示信息所在的控制资源集合(CORESET)和高层信令。如高层信令指示控制资源集合中检测的第一指示信息是否包括第一字域。
在又一种实现方式中,第一指示信息中是否包括第一字域取决于第一指示信息所在的控制资源集合(CORESET)、第一指示信息的格式和高层信令。如高层信令指示控制资源集合中检测的第一格式的第一指示信息是否包括第一字域。
可选的,若第一指示信息是DCI,DCI不包括指示第一参考信号资源集合的目标有效时序偏移值的第一字域,那么第一格式可以是DCI格式(format)0-2,也可以是DCI格式1-2,还可以是DCI格式2-3。
若第一指示信息中不包括第一字域,则终端设备确定第一参考信号资源集合的目标有效时序偏移值的实现方式可以如下:
第一种情况:触发的第一参考信号资源集合包括一个参考信号资源集合。
一种实现方式1.1中,可以将第二指示信息指示的第一参考信号资源集合对应的有效时序偏移值列表中的,第一个有效时序偏移值,确定为第一参考信号资源集合的目标有效时序偏移值。例如,第二指示信息指示的第一参考信号资源集合对应的有效时序偏移值列表为{1,2,3,4},则第一参考信号资源集合的目标有效时序偏移值为1。
一种实现方式1.2中,可以确定第一参考信号资源集合的目标有效时序偏移值等于0。
第二种情况:触发的第一参考信号资源集合包括N个参考信号资源集合,N为大于1的正整数。
其中,第二指示信息指示的第一参考信号资源集合对应的有效时序偏移值列表包括N个有效时序偏移值列表,N个参考信号资源集合与N个有效时序偏移值列表对应。N个参考信号资源可以按照预设次序进行排序。预设次序可以是指N个参考信号资源集合按照集合索引值从小到大(或者从大到小)的次序,也可以是指N个参考信号资源集合按照优先级排序后的次序。
一种实现方式2.1中,将N个参考信号资源集合中的第一个参考信号资源集合对应的有效时序偏移值列表中的,第一个有效时序偏移值,确定为第一个参考信号资源集合的目标有效时序偏移值。其中,第一个参考信号资源集合对应的有效时序偏移值列表为N个有效时序偏移值列表中的列表。将N个参考信号资源集合中的第i个参考信号资源集合对应的有效时序偏移值列表中的,与N个参考信号资源集合中的前i-1个参考信号资源集合的有效时序偏移值确定的第二时间单元均不同的,第一个有效时序偏移值,确定为第i个参考信号资源集合的目标有效时序偏移值。其中,第i个参考信号资源集合对应的有效时序偏移值列表为N个有效时序偏移值列表中的列表,i=2,3,…,N。例如,请参阅图6,图6是本申请实施例提供的一种第一参考信号传输时序示意图。如图6的(a)所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合,N=2,触发的非周期SRS资源集合包括2个参考信号资源集合(SRS resource set#1和SRS resource set#2),第二指示信息指示的该非周期SRS资源集合对应的有效时序偏移值列表包括2个有效时序偏移值列表(如{0,1,2,3}和{0,2,3,5}),这2个有效时序偏移值列表分别为2个参考信号资源集合对应的有效时序偏移值列表(如第一个参考信号资源集合对应{0,1,2,3},第二个参考信号资源集合对应{0,2,3,5})。第一个参考信号资源集合的目标有效时序偏移值为0,根据目标有效时序偏移值0确定的第二时间单元是2(在时隙2上第一个参考信号资源集合上发送第一个参考信号资源集合对应的参考信号);若第二个参考信号资源集合的有效时序偏移值为0,根据有效时序偏移值0确定的第二时间单元也是时隙2,该第二时间单元与第一个参考信号资源集合的第二时间单元相同,无法在同一时间单元上同时发送第一个参考信号资源集合和第二个参考信号资源集合对应的参考信号,则第二个参考信号资源集合的目标有效时序偏移值就为第二个参考信号资源集合对应的有效时序偏移值列表中,与第一个参考信号资源集合的目标有效时序偏移值0确定的第二时间单元(时隙2)不同的,第一个有效时序偏移值2,根据有效时序偏移值2确定第二个参考信号资源集合的第二时间单元是7,在时隙7上第二个参考信号资源集合上发送其(第二个参考信号资源集合)对应的参考信号。
一种实现方式2.2中,确定N个参考信号资源集合中的第i个参考信号资源集合的目标有效时序偏移值为i-1,i=1,2,…,N。例如,N=2,触发的第一参考信号资源集合包括2个参考信号资源集合,第一个参考信号资源集合的目标有效时序偏移值为0,第二个参考信号资源集合的目标有效时序偏移值为1。
一种实现方式2.3中,确定N个参考信号资源集合中的第i个参考信号资源集合的目标有效时序偏移值为0,i=1,2,…,N。例如,N=2,触发的第一参考信号资源集合包括2个参考信号资源集合,第一个参考信号资源集合的目标有效时序偏移值为0,第二个参考信号资源集合的目标有效时序偏移值为0。
相应地,若网络设备发送给终端设备的第一指示信息中不包括第一字域,则网络设备可以确定第一参考信号资源集合的目标有效时序偏移值,从而使得网络设备可以在目标有效时序偏移值确定的第二时间单元上接收第一参考信号。网络设备确定第一参考信号资源集合的目标有效时序偏移值的具体实现方式,可以参照上述终端设备确定第一参考信号资源集合的目标有效时序偏移值的具体实现,为避免重复,在此不再赘述。
可以理解,本申请各实施例中,因为终端设备没有能力同时传输两个参考信号,或者终端设备在一个时刻仅有部分天线用于发送,因此需要避免多个参考信号的同时传输。一种场景下,第一指示信息中不包括第一字域,且第一指示信息触发至少两个参考信号资源集合,若至少两个参考信号资源集合在同一个时间单元上没有重叠(overlap)时,可以在同一个时间单元上确定至少两个参考信号资源集合的第二时间单元,此时可以将N个参考信号资源集合中的第i个参考信号资源集合对应的有效时序偏移值列表中的,第一个有效时序偏移值,确定为第i个参考信号资源集合的目标有效时序偏移值;也可以将N个参考信号资源集合中的第一个参考信号资源集合对应的有效时序偏移值列表中的,第一个有效时序偏移值,确定为第i个参考信号资源集合的目标有效时序偏移值,i=1,2,3,…,N,例如,N=2,可以将第一个参考信号资源集合对应的有效时序偏移值列表中的,第一个有效时序偏移值,确定为第一个参考信号资源集合和第二个参考信号资源集合的目标有效时序偏移值。另一种场景下,第一指示信息中不包括第一字域,且第一指示信息触发至少两个参考信号资源集合,至少两个参考信号资源集合在不同第二时间单元进行传输。在一种可能的实现方式中,在不同第二时间单元进行传输的该至少两个参考信号资源集合是用于天线切换的SRS资源集合(如1T4R,2T8R等)。在另一种可能的实现方式中,在不同第二时间单元进行传输的该至少两个参考信号资源集合对应多个TRP。本申请实施例,可以有效避免由于终端能力无法同时在多个SRS资源集合上发送多个SRS带来的SRS丢弃的问题。
503、终端设备根据第一参考信号资源集合的目标有效时序偏移值,在第二时间单元上的第一参考信号资源集合上发送第一参考信号资源集合对应的参考信号。
第二时间单元为以第三时间单元为起始,有效的传输时间单元中,第一参考信号资源集合的目标有效时序偏移值指示的时间单元。
在上述实现方式1.1和1.2中,第三时间单元等于第一时间单元,或者第三时间单元可以通过高层信令配置。
在上述实现方式2.1和2.2中,N个参考信号资源集合中的第一个参考信号资源集合的第三时间单元可以等于第一时间单元,也可以通过高层信令配置。N个参考信号资源集合 中的第i个参考信号资源集合的第三时间单元可以等于第一时间单元,也可以通过高层信令配置,还可以为第i-1个参考信号资源集合的第二时间单元。
在上述实现方式2.3中,N个参考信号资源集合中的第一个参考信号资源集合的第三时间单元可以等于第一时间单元,也可以通过高层信令配置。N个参考信号资源集合中的第i个参考信号资源集合的第三时间单元为第i-1个参考信号资源集合的第二时间单元,或者N个参考信号资源集合中的第i个参考信号资源集合的第三时间单元为第i-1个参考信号资源集合的第二时间单元+1。
上述的各个实现方式中,第三时间单元可以为:

相应地,网络设备可以根据第一参考信号资源集合的目标有效时序偏移值,在第二时间单元上的第一参考信号资源集合上接收第一参考信号。
在一个实施例中,以第一参考信号是非周期SRS,第二指示信息是DCI为例。请参阅图7,图7是本申请实施例提供的一种第一参考信号传输时序示意图。如图7所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合,且该DCI中不包括指示非周期SRS资源集合的目标有效时序偏移值的第一字域,该触发的SRS资源集合是一个SRS资源集合。
一种情况下,如图7的(a),高层信令配置SRS资源集合的参考时序偏移值为6,SRS资源集合对应的有效时序偏移值列表为{0,1,2,3,4,5,6,7}。那么可以确定SRS资源集合的目标有效时序偏移值为有效时序偏移值列表中的第一个有效时序偏移值0,则在DCI所在的时隙0后偏移6个时隙(即时隙6为第三时间单元),再在时隙6后的第1个有效的时隙上的SRS资源集合上发送SRS。由于F和U均为有效的时隙,时隙6后的第1个有效的时隙是时隙7,因此最终在时隙7上SRS资源集合上发送SRS。或者,高层信令配置SRS资源集合的第三时间单元为时隙6,SRS资源集合对应的有效时序偏移值列表为{0,1,2,3,4,5,6,7}。那么可以确定SRS资源集合的目标有效时序偏移值为有效时序偏移值列表中的第一个有效时序偏移值0,则在时隙6后的第1个有效的时隙上的SRS资源集合上发送SRS。由于F和U均为有效的时隙,时隙6后的第1个有效的时隙是时隙7,因此最终在时隙7上SRS资源集合上发送SRS。
另一种情况下,如图7的(b),SRS资源集合的(第三时间单元)参考时隙是触发SRS资源集合的DCI所在的时隙,则参考时隙为时隙0,SRS资源集合对应的有效时序偏移值列表为{0,1,2,3,4,5,6,7}。那么可以确定SRS资源集合的目标有效时序偏移值为有效时序偏移值列表中的第一个有效时序偏移值0,则在时隙0后的第1个有效的时隙上的SRS资源集合上发 送SRS。由于F和U均为有效的时隙,时隙0后的第1个有效的时隙是时隙7,因此最终在时隙7上SRS资源集合上发送SRS。
在另一个实施例中,以第一参考信号是非周期SRS,第二指示信息是DCI为例。如图6所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。一种情况下,如图6的(b),终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合,且该DCI中不包括指示非周期SRS资源集合的目标有效时序偏移值的第一字域,该触发的SRS资源集合是两个SRS资源集合,第一个SRS资源集合#1(SRS resource set#1)对应的有效时序偏移值列表为{0,1},第二个SRS资源集合#2(SRS resource set#2)对应的有效时序偏移值列表为{0,1}。那么可以确定第一个SRS资源集合的目标有效时序偏移值为有效时序偏移值列表中的第一个有效时序偏移值0,在DCI所在的时隙0后的第1个有效的时隙上第一个SRS资源集合上发送第一个SRS资源集合对应的SRS,由于F和U对于第一个SRS资源集合均为有效的时隙,时隙0后的第1个有效的时隙是时隙2,因此最终在时隙2上第一个SRS资源集合上发送其(第一个SRS资源集合)对应的SRS。第二个SRS资源集合的目标有效时序偏移值为有效时序偏移值列表中的,与第一个SRS资源集合的目标有效时序偏移值0确定的有效时隙(时隙2)不同的,第一个有效时序偏移值为1(即确定第二个SRS资源集合的目标有效时序偏移值为1)。在DCI所在的时隙0后的第2个有效的时隙上第二个SRS资源集合上发送第二个SRS资源集合对应的SRS,由于F和U对于第二个SRS资源集合均为有效的时隙,时隙0后的第2个有效的时隙是时隙3,因此最终在时隙3上第二个SRS资源集合上发送第二个SRS资源集合对应的SRS。
另一种情况下,如图6的(c),终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合,且该DCI中不包括指示非周期SRS资源集合的目标有效时序偏移值的第一字域,该触发的SRS资源集合是两个SRS资源集合,第一个SRS(SRS#1)资源集合对应的有效时序偏移值列表为{0,1},第二个SRS(SRS#2)资源集合对应的有效时序偏移值列表为{0,2}。那么可以确定第一个SRS资源集合的目标有效时序偏移值为对应的有效时序偏移值列表中的第一个有效时序偏移值0,在DCI所在的时隙0后的第1个有效的时隙上第一个SRS资源集合上发送其(第一个SRS资源集合)对应的SRS,由于F和U对于第一个SRS资源集合均为有效的时隙,时隙0后的第1个有效的时隙是时隙2,因此最终在时隙2上第一个SRS资源集合上发送第一个SRS资源集合对应的SRS。将时隙2作为第二个SRS资源集合的参考时间单元(第三时间单元),第二个SRS资源集合的目标有效时序偏移值为对应的有效时序偏移值列表中的第一个有效时序偏移值0,在时隙2后的第一个有效的时隙上第二个SRS资源集合上发送第二个SRS资源集合对应的SRS,由于F和U对于第二个SRS资源集合均为有效的时隙,时隙2后的第一个有效的时隙是时隙3,因此最终在时隙3上第二个SRS资源集合上发送第二个SRS资源集合对应的SRS。又例如,如图6的(c),终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合,且该DCI中不包括指示非周期SRS资源集合的目标有效时序偏移值的第一字域,该触发的SRS资源集合是两个SRS资源集合,第一个SRS(SRS#1)资源集合对应的有效时序偏移值列表为{0,1},第二个SRS(SRS#2)资源集合对应的有效时序偏移值列表为{0,2}。那么可以确定第一个SRS资源集合的目标有效时序偏移值为对应的有效时序偏移值列表中的第一个有效时序偏移值0,在DCI所在的时隙0为起始的第1个有效的 时隙上第一个SRS资源集合上发送其(第一个SRS资源集合)对应的SRS,由于F和U对于第一个SRS资源集合均为有效的时隙,时隙0为起始的第1个有效的时隙是时隙2,因此最终在时隙2上第一个SRS资源集合上发送第一个SRS资源集合对应的SRS。将时隙2作为第二个SRS资源集合的参考时间单元(第三时间单元),第二个SRS资源集合的目标有效时序偏移值为对应的有效时序偏移值列表中的第一个有效时序偏移值0,在时隙2+1(3)为起始的第1个有效的时隙上第二个SRS资源集合上发送第二个SRS资源集合对应的SRS,由于F和U对于第二个SRS资源集合均为有效的时隙,时隙2+1(3)为起始的第1个有效的时隙是时隙3,因此最终在时隙3上第二个SRS资源集合上发送第二个SRS资源集合对应的SRS。
基于上述的网络架构,请参阅图8,图8是本申请实施例提供的另一种通信方法的流程示意图。其中,本申请中由终端设备执行的功能也可以由终端设备侧的各种形态的装置/设备(例如,芯片)来执行,本申请中由网络设备执行的功能也可以由网络设备侧的各种形态的装置/设备(例如,芯片)来执行。如图8所示,该通信方法可以包括以下步骤。
801、网络设备向终端设备发送用于指示第一参考信号资源集合对应的参考时序偏移值列表的第三指示信息。
相应地,终端设备接收来自网络设备的用于指示第一参考信号资源集合对应的参考时序偏移值列表的第三指示信息。
其中,第一参考信号可以包括SRS、DMRS等。第一参考信号资源集合可以是一个或多个参考信号资源集合,一个参考信号资源集合可以对应一个或多个参考信号,参考信号可以为非周期参考信号。
第三指示信息可以是RRC,也可以是MAC CE。
可选地,第三指示信息通常会给每个参考信号资源集合(resource set)指示一个参考时序偏移值列表,该列表包括一个或多个参考时序偏移值。
可选地,如果是下行,第一参考信号还可以包括CSI-RS。例如,网络设备向终端设备发送第三指示信息和参考信号,终端设备可以根据第三指示信息确定参考时间单元,在参考时间单元后的第一个有效的时间单元上接收网络设备发送的参考信号。
802、网络设备在第一时间单元上向网络设备发送触发第一参考信号资源集合的第一指示信息。
相应地,终端设备在第一时间单元上接收来自网络设备的触发第一参考信号资源集合的第一指示信息。第一指示信息可以是DCI。
可选地,第一指示信息可以携带有第二字域,第二字域指示第一参考信号资源集合对应的参考时序偏移值列表中的一个参考时序偏移值。终端设备可以将第二字域指示的这个参考时序偏移值确定为第一参考信号资源集合的目标参考时序偏移值。
可以理解,字域(filed)也可以称为字段,本申请对此不作限定。
803、终端设备判断第一指示信息中是否包括指示第一参考信号资源集合的目标参考时序偏移值的第二字域,若包括,执行步骤804;若不包括,执行步骤805。
在一种实现方式中,第一指示信息是否包括第二字域可以取决于第一指示信息的格式。
在另一种实现方式中,第一指示信息是否包括第二字域可以取决于第一指示信息的格 式和高层信令。如第一格式的第一指示信息中是否存在第二字域,由高层信令配置。高层信令可以是RRC信令,也可以是MAC CE,还可以是其它能够实现配置第一指示信息中是否存在第二字域,这一功能的其它信令。
在又一种实现方式中,第一指示信息中是否包括第二字域取决于第一指示信息所在的控制资源集合(CORESET)和高层信令。如高层信令指示控制资源集合中检测的第一指示信息是否包括第二字域。
在又一种实现方式中,第一指示信息中是否包括第二字域取决于第一指示信息所在的控制资源集合(CORESET)、第一指示信息的格式和高层信令。如高层信令指示控制资源集合中检测的第一格式的第一指示信息是否包括第二字域。
可选的,若第一指示信息是DCI,DCI不包括指示第一参考信号资源集合的目标参考时序偏移值的第二字域,第一格式可以是DCI格式(format)0-2,也可以是DCI格式1-2,还可以是DCI格式2-3。
终端设备接收到来自网络设备的第一指示信息后,若判断到第一指示信息中包括第二字域,则可以执行步骤804;若判断到第一指示信息中不包括第二字域,则可以执行步骤805。
804、终端设备根据目标参考时序偏移值确定第一参考信号资源集合的参考时间单元。
终端设备判断到第一指示信息包括第二字域,第二字域指示第一参考信号资源集合的目标参考时序偏移值。那么终端设备可以直接根据第二字域确定第一参考信号资源集合的目标参考时序偏移值。再根据目标参考时序偏移值确定第一参考信号资源集合的参考时间单元:可以确定第一参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,目标参考时序偏移值指示的时间单元。其中,第四时间单元可以等于第一时间单元,也可以通过高层信令配置。
可以理解,传输时间单元不同于上述的有效时间单元。传输时间单元指的是包括下行的时间单元的所有时间单元。
在一个实施例中,请参阅图9,图9是本申请实施例提供的又一种第一参考信号传输时序示意图。如图9所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合且携带第二字域指示参考时序偏移值,则可以实现非周期SRS的灵活传输。例如:如图9的(a)所示,触发非周期SRS资源集合的DCI中,第二字域指示SRS资源集合的参考偏移值为0,即目标参考时隙为时隙0,由于在该参考时隙0后的第一个有效时隙为时隙2,那么终端设备在时隙2上SRS资源集合上发送SRS。又例如:如图9的(b)所示,触发非周期SRS资源集合的DCI中,第二字域指示SRS资源集合的参考偏移值为6,即目标参考时隙为时隙6,由于在该参考时隙6后的第一个有效时隙为时隙7,那么终端设备在时隙7上SRS资源集合上发送SRS。
在一个实施例中,网络设备会向终端设备发送第一参考信号资源集合对应的参考时序偏移值的列表为{1,2,3,4},第一指示信息中的第二字域为该列表中的参考时序偏移值3,则终端设备设备可以根据第二字域确定第一参考信号资源集合的目标参考时序偏移值为3。终端设备在时隙0上接收到第一指示信息,则终端设备可以在第一指示信息所在的时隙0后偏移3个时隙(即时隙3),则确定时隙3为第一参考信号资源集合对应的参考时间单元;或者终端设备在时隙0上接收到第一指示信息,高层信令配置第四时间单元为时隙1,则终端设 备可以在时隙1后偏移3个时隙(即时隙4),则确定时隙4为第一参考信号资源集合对应的参考时间单元。
805、终端设备根据第一参考信号资源集合对应的参考时序偏移值列表确定第一参考信号资源集合的参考时间单元。
终端设备判断到第一指示信息不包括第二字域,第二字域指示第一参考信号资源集合的目标参考时序偏移值。那么终端设备可以根据第一参考信号资源集合对应的参考时序偏移值列表确定第一参考信号资源集合的参考时间单元,具体实现方式可以如下:
第一种情况:触发的第一参考信号资源集合包括一个参考信号资源集合。
一种实现方式3.1中,将第一参考信号资源集合对应的参考时序偏移值列表中的第一个参考时序偏移值,确定为第一参考信号资源集合的目标参考时序偏移值,确定第一参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,第一参考信号资源集合的目标参考时序偏移值指示的时间单元。例如,第三指示信息指示的第一参考信号资源集合对应的参考时序偏移值列表为{1,2,3,4},则第一参考信号资源集合的目标参考时序偏移值为1。第一参考信号资源集合的参考时间单元为第四时间单元+1的时间单元。第四时间单元可以等于第一时间单元,也可以通过高层信令配置。
一种实现方式3.2中,确定第一参考信号资源集合的目标参考时序偏移值等于0,确定第一参考信号资源集合的参考时间单元为第四时间单元。第四时间单元可以等于第一时间单元,也可以通过高层信令配置。
第二种情况:触发的第一参考信号资源集合包括N个参考信号资源集合,N为大于1的正整数。
其中,第三指示信息指示的第一参考信号资源集合对应的参考时序偏移值列表包括N个参考时序偏移值列表,N个参考信号资源集合与N个参考时序偏移值列表对应。N个参考信号资源可以按照预设次序进行排序。预设次序可以是指N个参考信号资源集合按照集合索引值从小到大(或者从大到小)的次序,也可以是指N个参考信号资源集合按照优先级排序后的次序。
一种实现方式4.1中,将N个参考信号资源集合中的第一个参考信号资源集合对应的参考时序偏移值列表中的,第一个参考时序偏移值,确定为第一个参考信号资源集合的目标参考时序偏移值。其中,第一个参考信号资源集合对应的参考时序偏移值列表为N个参考时序偏移值列表中的列表。确定第一个参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,第一个参考信号资源集合的目标参考时序偏移值指示的时间单元。在该参考时间单元后的第一个有效时间单元上第一个参考信号资源集合上发送其(第一个参考信号资源集合)对应的参考信号。
将N个参考信号资源集合中的第i-1个参考信号资源集合的参考时间单元后的第一个有效时间单元确定为N个参考信号资源集合中的第i个参考信号资源集合的参考时间单元,在该参考时间单元后的第一个有效时间单元上第i个参考信号资源集合上发送其(第i个参考信号资源集合)对应的参考信号,i=2,3,…,N。如图6的(d)所示,例如,N=2,触发的第一参考信号资源集合包括2个参考信号资源集合,第三指示信息指示的第一参考信号资源集合对应的参考时序偏移值列表包括2个参考时序偏移值列表(如{1,2,3,4}和{1,2,7,8}),这2个 参考时序偏移值列表分别为2个参考信号资源集合对应的参考时序偏移值列表(如第一个参考信号资源集合对应{1,2,3,4},第二个参考信号资源集合对应{1,2,7,8})。第一个参考信号资源集合的目标参考时序偏移值为1,根据目标有效时序偏移值1确定的参考时间单元是1,则在时隙1后的第1个有效时间单元(时隙2)上第一个参考信号资源集合上发送第一个参考信号资源集合对应的参考信号;第二个参考信号资源集合的参考时间单元为时隙2,在时隙2后的第一个有效时间单元(时隙3)上第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号。
其中,N个参考信号资源集合中的第一个参考信号资源集合的第四时间单元可以等于第一时间单元,也可以通过高层信令配置。N个参考信号资源集合中的第i个参考信号资源集合的第四时间单元可以等于第一时间单元,也可以通过高层信令配置,还可以为第i-1个参考信号资源集合的参考时间单元。
一种实现方式4.2中,将N个参考信号资源集合中的第一个参考信号资源集合对应的参考时序偏移值列表中的,第一个参考时序偏移值,确定为第一个参考信号资源集合的目标参考时序偏移值。其中,第一个参考信号资源集合对应的参考时序偏移值列表为N个参考时序偏移值列表中的列表。确定第一个参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,第一个参考信号资源集合的目标参考时序偏移值指示的时间单元。在该参考时间单元后的第一个有效时间单元上第一个参考信号资源集合上发送其(第一个参考信号资源集合)对应的参考信号。
将N个参考信号资源集合中的第i个参考信号资源集合对应的参考时序偏移值列表中的,与N个参考信号资源集合中的前i-1个参考信号资源集合的参考时序偏移值确定的用于发送参考信号的时间单元均不同的,第一个参考时序偏移值,确定为第i个参考信号资源集合的目标参考时序偏移值。其中,第i个参考信号资源集合对应的参考时序偏移值列表为N个参考时序偏移值列表中的列表,i=2,3,…,N。确定第i个参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,第i个参考信号资源集合的目标参考时序偏移值指示的时间单元。在该参考时间单元后的第一个有效时间单元上第i个参考信号资源集合上发送其(第i个参考信号资源集合)对应的参考信号。
其中,N个参考信号资源集合中的第一个参考信号资源集合的第四时间单元可以等于第一时间单元,也可以通过高层信令配置。N个参考信号资源集合中的第i个参考信号资源集合的第四时间单元可以等于第一时间单元,也可以通过高层信令配置,还可以为第i-1个参考信号资源集合的参考时间单元,还可以为第i-1个参考信号资源集合的参考时间单元+1。
例如,如图6的(b)所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合。N=2,触发的非周期SRS资源集合包括2个参考信号资源集合(SRS resource set#1和SRS resource set#2),第二指示信息指示的该非周期SRS资源集合对应的参考时序偏移值列表包括2个参考时序偏移值列表(如{1,2}和{1,2}),这2个参考时序偏移值列表分别为2个参考信号资源集合对应的参考时序偏移值列表(如第一个参考信号资源集合对应{1,2},第二个参考信号资源集合对应{1,2})。第一个参考信号资源集合的目标参考时序偏移值为1,根据目标参考时序偏移值1确定的参 考时间单元是1,则在时隙1后第一个有效时间单元上(时隙2)第一个参考信号资源集合上发送第一个参考信号资源集合对应的参考信号;若第二个参考信号资源集合的参考时序偏移值为1,根据参考时序偏移值1确定的参考时间单元是1,则在时隙1后第一个有效时间单元上(时隙2)第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号,由于发送第二个参考信号资源集合对应的参考信号的时间单元与发送第一个参考信号资源集合对应的参考信号的时间单元相同,无法在同一时间单元上同时发送第一个参考信号资源集合和第二个参考信号资源集合对应的参考信号,因此第二个参考信号资源集合的目标参考时序偏移值就为第二个参考信号资源集合对应的参考时序偏移值列表中,与第一个参考信号资源集合的目标参考时序偏移值1确定的参考时间单元(时隙1)后的第一个有效时间单元(时隙2)不同的,第一个参考时序偏移值2,根据参考时序偏移值2确定参考时间单元是2,在时隙2后的第一个有效时间单元(时隙3)上第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号。
又例如,如图6的(b)所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合。N=2,触发的非周期SRS资源集合包括2个参考信号资源集合(SRS resource set#1和SRS resource set#2),第二指示信息指示的该非周期SRS资源集合对应的参考时序偏移值列表包括2个参考时序偏移值列表(如{0,1}和{0,2}),这2个参考时序偏移值列表分别为2个参考信号资源集合对应的参考时序偏移值列表(如第一个参考信号资源集合对应{0,1},第二个参考信号资源集合对应{0,2})。第一个参考信号资源集合的目标参考时序偏移值为0,根据目标参考时序偏移值0确定的参考时间单元是0,则在时隙0为起始的第一个有效时间单元上(时隙2)第一个参考信号资源集合上发送第一个参考信号资源集合对应的参考信号;若第二个参考信号资源集合的参考时序偏移值为0,根据参考时序偏移值0确定的参考时间单元是0,则在时隙0+1为起始的第一个有效时间单元上(时隙2)第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号,由于发送第二个参考信号资源集合对应的参考信号的时间单元与发送第一个参考信号资源集合对应的参考信号的时间单元相同,无法在同一时间单元上同时发送第一个参考信号资源集合和第二个参考信号资源集合对应的参考信号,因此第二个参考信号资源集合的目标参考时序偏移值就为第二个参考信号资源集合对应的参考时序偏移值列表中,与第一个参考信号资源集合的目标参考时序偏移值0确定的参考时间单元(时隙1)为起始的第一个有效时间单元(时隙2)不同的,第一个参考时序偏移值2,根据参考时序偏移值2确定参考时间单元是2,在时隙2+1为起始的第一个有效时间单元(时隙3)上第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号。
例如,如图6的(d)所示,D表示下行时隙,F表示灵活时隙,U表示上行时隙。终端设备在时隙0接收到DCI,该DCI触发了非周期SRS资源集合。N=2,触发的非周期SRS资源集合包括2个参考信号资源集合(SRS resource set#1和SRS resource set#2),第二指示信息指示的该非周期SRS资源集合对应的参考时序偏移值列表包括2个参考时序偏移值列表(如{1,2}和{1,3}),这2个参考时序偏移值列表分别为2个参考信号资源集合对应的参考时序偏移值列表(如第一个参考信号资源集合对应{1,2},第二个参考信号资源集合对应{1,3})。第一个参考信号资源集合的目标参考时序偏移值为1,根据目标参考时序偏移值1确定的参 考时间单元是1,则在时隙1后第一个有效时间单元上(时隙2)第一个参考信号资源集合上发送第一个参考信号资源集合对应的参考信号);第二个参考信号资源集合的参考时序偏移值为1,根据参考时序偏移值1确定的参考时间单元是1,则在时隙1后第一个有效时间单元上(时隙2)第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号。由于发送第二个参考信号资源集合对应的参考信号的时间单元与发送第一个参考信号资源集合对应的参考信号的时间单元相同,无法在同一时间单元上同时发送第一个参考信号资源集合和第二个参考信号资源集合对应的参考信号,则第二个参考信号资源集合的目标参考时序偏移值就为第二个参考信号资源集合对应的参考时序偏移值列表中,与第一个参考信号资源集合的目标参考时序偏移值1确定的参考时间单元起的第一个有效时间单元不同的,第一个参考时序偏移值3,根据参考时序偏移值3确定参考时间单元是3,在时隙3后的第一个有效时间单元(时隙7)上第二个参考信号资源集合上发送第二个参考信号资源集合对应的参考信号。
一个实现方式4.3中,确定N个参考信号资源集合中的第i个参考信号资源集合的目标参考时序偏移值为i-1,i=1,2,…,N。例如,N=2,触发的第一参考信号资源集合包括2个参考信号资源集合,第一个参考信号资源集合的目标参考时序偏移值为0,第二个参考信号资源集合的目标参考时序偏移值为1。确定第i个参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,第i个参考信号资源集合的目标参考时序偏移值指示的时间单元。在该参考时间单元后的第一个有效时间单元上第i个参考信号资源集合上发送其(第i个参考信号资源集合)对应的参考信号。N个参考信号资源集合中的第一个参考信号资源集合的第四时间单元可以等于第一时间单元,也可以通过高层信令配置。N个参考信号资源集合中的第i个参考信号资源集合的第四时间单元为第i-1个参考信号资源集合的参考时间单元后的第一个有效时间单元+1。
一种实现方式4.4中,确定N个参考信号资源集合中的第i个参考信号资源集合的目标参考时序偏移值为0,i=1,2,…,N。例如,N=2,触发的第一参考信号资源集合包括2个参考信号资源集合,第一个参考信号资源集合的目标参考时序偏移值为0,第二个参考信号资源集合的目标参考时序偏移值为0。确定第i个参考信号资源集合的参考时间单元为以第四时间单元为起始,传输时间单元中,第i个参考信号资源集合的目标参考时序偏移值指示的时间单元。在该参考时间单元后的第一个有效时间单元上第i个参考信号资源集合上发送其(第i个参考信号资源集合)对应的参考信号。N个参考信号资源集合中的第一个参考信号资源集合的第四时间单元可以等于第一时间单元,也可以通过高层信令配置。N个参考信号资源集合中的第i个参考信号资源集合的第四时间单元为第i-1个参考信号资源集合的参考时间单元后的第一个有效时间单元+1。
上述的各个实现方式中,参考时间单元可以为:

相应地,若网络设备发送给终端设备的第一指示信息中不包括第二字域,则网络设备可以确定第一参考信号资源集合的目标参考时序偏移值,从而使得网络设备可以在目标参考时序偏移值确定的参考时间单元上后的第一个有效时间单元上接收第一参考信号。网络设备确定第一参考信号资源集合的参考时间单元的具体实现方式,可以参照上述终端设备确定第一参考信号资源集合的参考时间单元的具体实现,为避免重复,在此不再赘述。
可以理解,本申请各实施例中,因为终端设备没有能力同时传输两个参考信号,或者终端设备在一个时刻仅有部分天线用于发送,因此需要避免多个参考信号的同时传输。一种场景下,第一指示信息中不包括第二字域,且第一指示信息触发至少两个参考信号资源集合,若至少两个参考信号资源集合在同一个时间单元上没有重叠(overlap)时,可以在同一个时间单元上确定至少两个参考信号资源集合的发送参考信号资源集合对应参考信号的时间单元,此时可以将N个参考信号资源集合中的第i个参考信号资源集合对应的参考时序偏移值列表中的,第一个参考时序偏移值,确定为第i个参考信号资源集合的目标参考时序偏移值;也可以将N个参考信号资源集合中的第一个参考信号资源集合对应的参考时序偏移值列表中的,第一个参考时序偏移值,确定为第i个参考信号资源集合的目标参考时序偏移值,i=1,2,3,…,N,例如,N=2,可以将第一个参考信号资源集合对应的参考时序偏移值列表中的,第一个参考时序偏移值,确定为第一个参考信号资源集合和第二个参考信号资源集合的目标参考时序偏移值。另一种场景下,第一指示信息中不包括第二字域,且第一指示信息触发至少两个参考信号资源集合,至少两个参考信号资源集合在不同第二时间单元进行传输。在一种可能的实现方式中,在不同发送参考信号的时间单元进行传输的该至少两个参考信号资源集合是用于天线切换的SRS资源集合(如1T4R,2T8R等)。在另一种可能的实现方式中,在不同发送参考信号的时间单元进行传输的该至少两个参考信号资源集合对应多个TRP。本申请实施例,可以有效避免由于终端能力无法同时在多个SRS资源集合上发送多个SRS带来的SRS丢弃的问题。
806、终端设备在参考时间单元后的第一个有效时间单元上的第一参考信号资源集合上发送第一参考信号资源集合对应的参考信号。
