为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
在第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)标准化进展中,第15版本(Release15,Rel-15)中提出了传输配置指示(Transmission Configuration Indicator,TCI)状态的概念,用于下行的空间域QCL(波束)指示,以及时域频域的QCL信息的传递。具体来说,准共址(Quasi-co-located,QCL)关系可以简单描述为从某一个源参考信号指向一个目标参考信号的大尺度衰落的关系。对于波束指示来说,当终端设备在从网络得到两个源和目标参考信号的QCL关系后,在对目标参考信号的接收时可以使用之前接收源参考信号的接收波束。具体的介绍如下:
TCI状态的配置和指示包括无线资源控制(Radio Resource Control,RRC)配置,媒体接入控制层控制单元(Media Access Control Control Element,MAC CE)激活以及下行控制信息(Downlink Control Information,DCI)指示三个步骤,其具体过程如下:
RRC通过PDSCH配置(PDSCH-Config)为终端配置最多M个TCI状态,其中M的取值由终端能力确定。
MAC CE激活最多8个TCI状态组用以映射到DCI中的3比特TCI信息域。其中MAC CE激活的每个TCI状态组可以包含1个或2个TCI状态。如果高层参数配置DCI中包含TCI指示域时,DCI格式1_1可以从MAC激活的TCI状态组中指示一个TCI状态组。如果高层参数配置DCI中不包含TCI指示域或者数据是通过DCI格式1_0来调度时,DCI中将不包含TCI状态指示域。
其中,一个TCI状态可以包含如下配置:
TCI状态ID,用于标识一个TCI状态;
QCL信息1;
QCL信息2。
其中,一个QCL信息又包含如下信息:
QCL类型(type)配置,可以是QCL type A,QCL type B,QCL type C,QCL type D中的一个;
QCL参考信号配置,包括参考信号所在的小区标识(Identity,ID),带宽部分(Band Width Part,BWP)ID以及参考信号信息(可以是信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)资源ID或同步信号块(Synchronization Signal Block,SSB)索引)。
其中,不同QCL类型配置的定义如下:
'QCL-TypeA':{多普勒频移(Doppler shift),多普勒扩展(Doppler spread),平均时延(average delay),延时扩展(delay spread)};
'QCL-TypeB':{多普勒频移(Doppler shift),多普勒扩展(Doppler spread)};
'QCL-TypeC':{多普勒频移(Doppler shift),平均时延(average delay)};
'QCL-TypeD':{空间接收参数(Spatial Rx parameter)}。
上述TCI状态(state)的指示机制仅适用于下行的信道和信号,且在NR系统中应用起来有诸多的限制。为了给NR系统提供一个更统一的上下行波束管理机制,在参照第15版本(Release15,Rel-15)或第16版本(Release16,Rel-16)的TCI状态的设计基础上,第17版本(Release17,Rel-17)提出了统一的TCI state(unified TCI state)的概念,它增加了重要新功能举例如下:
设计了3种unified TCI state的模式,即联合TCI状态(joint TCI state)适用于上下行的信道和信号;下行TCI state仅适用于下行的信道和信号;上行TCI state仅适用于上行的信道和信号。
下行信道(部分物理下行控制信道(Physical Downlink Control Channel,PDCCH),物理下行共享信道(Physical Downlink Shared Channel,PDSCH))和信号(非周期信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS))使用相同的下行发射指示波束,使用下行TCI state或联合TCI state。
上行信道(物理上行控制信道(Physical Uplink Control Channel,PUCCH),物理上行共享信道(Physical Uplink Shared Channel,PUSCH))和信号(探测参考信号(Sounding Reference Signal,SRS))使用相同的上行发射波束,使用上行TCI state或联合TCI state。
统一的TCI state可以使用MAC CE和/或DCI动态更新和指示。
适用于载波聚合(Carrier Aggregation,CA)的场景,单载波单元(Component carrier,CC)上的波束指示可以适用于多个不同的CC。
支持小区间的波束管理功能。
由于Rel-17中统一的TCI state的第一种指示方式可以通过RRC配置、MAC CE来激活,或者第二种指示方式可以通过RRC配置、MAC CE激活并通过DCI动态指示的方式。对于DCI动态指示统一的TCI state的情况,该DCI中指示的TCI state对应的新波束(beam)会在波束应用时间后生效。对于MAC CE激活的TCI state对应的新beam,会遵循MAC CE的生效时间。
波束应用时间(Beam Application Time,BAT):在Rel-17中,BAT如图2所示,通过下行DCI指示统一的TCI state,并且该下行DCI可以有对应调度的PDSCH,也可以没有对应调度的PDSCH,BAT的时间起点是承载对应的混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈的PUCCH的最后一个符号,假设BAT为Y个符号,从该PUCCH的最后一个符号到时隙n的第一个符号之间大于或等于Y个符号。因此在时隙n及之后时隙传输的各信道和信号采用新beam,在时隙n之前传输的各信道和信号采用旧beam。其中,旧beam为波束应用时间之前的beam,或波束更新之前的beam。
为便于更好的理解本申请实施例,对本申请相关的Rel-15/Rel-16/Rel-17中各信道的波束确定进行说明。
上行信道或信号:对于PUSCH,PUCCH,UE接收到DCI或MAC CE指示的TCI state,则在BAT之后的第一个时隙采用该TCI state对应的beam;若在BAT之后的第一个时隙之前,则采用旧beam。对于SRS,可以通过RRC信令配置是否应用Rel-17规定的unified TCI机制,若配置为‘是’,则也按照BAT时间线,若配置为‘否’,则不应用Rel-17的机制。
下行信道或信号:对于PDSCH,UE接收到DCI或MAC CE指示的TCI state,则在BAT之后的第一个时隙采用该TCI state对应的beam;若在BAT之后的第一个时隙之前,则采用旧beam。对于非周期CSI-RS,可以通过RRC信令配置是否应用Rel-17规定的unified TCI机制,若配置为‘是’,则也按照BAT时间线,若配置为‘否’,则不应用Rel-17的机制。对于周期CSI-RS和半持续CSI-RS,不应用Rel-17规定的unified TCI机制。
为便于更好的理解本申请实施例,对本申请相关的Rel-17多发送接收点(Transmission Reception Point,TRP)的PUSCH传输和PUCCH传输进行说明。
在NR Rel-17中讨论了单DCI调度的上行的多TRP PUSCH传输方案,但NR Rel-17中只讨论了 PUSCH时分复用(time-division multiplexing,TDM)重复传输(repetition)的方案。如果RRC配置了两个SRS资源集合,则UE可以以TDM repetition的方式向两个TRP发送PUSCH。UE向两个TRP发送的PUSCH repetition按照循环映射(cyclic mapping)或顺序映射(sequential mapping)的方式进行TDM repetition。
对于NR Rel-17中讨论的多TRP PUCCH传输,每个PUCCH资源可以配置与一个空间关系或两个空间关系相关联。若配置为与两个空间关系相关联,则按照循环映射(cyclic mapping)或顺序映射(sequential mapping)的方式进行TDM repetiton。
为便于更好的理解本申请实施例,对本申请解决的问题进行说明。
在NR Rel-17中,统一的TCI机制只应用到单TRP系统中,并未涉及PUSCH repetition,PUCCH repetition,PDSCH repetition的场景。如图3所示,以PUSCH repetition为例,若在PUSCH repetition的期间,新beam生效(新的TCI),此种场景下终端侧和网络设备侧对波束的认知可能不同。
对于第18版本(Release18,Rel-18),统一的TCI机制会扩展应用到多个TRP/天线面板(panel)的场景,在此场景下,存在如下可能的情况:
下行DCI/MAC CE指示2个联合TCI state,或者,2个上行TCI state和/或2个下行的TCI state,UE通过2个TCI state发送上行信道或信号,或者UE通过2个TCI state接收下行信道或信号;
下行DCI/MAC CE指示2个联合TCI state,或者,2个上行TCI state和/或2个下行的TCI state,UE向通过1个TCI state发送上行信道或信号,或者UE通过1个TCI state接收下行信道或信号;
下行DCI指示1个联合TCI state,或者,1个上行TCI state和/或1个下行的TCI state,UE通过2个TCI state发送上行信道或信号,或者UE通过2个TCI state接收下行信道或信号;
下行DCI指示1个联合TCI state,或者,1个上行TCI state和/或1个下行的TCI state,UE通过1个TCI state发送上行信道或信号,或者UE通过1个TCI state接收下行信道或信号。
在这些场景下,上行或下行信道在时域进行多次发送的期间,若新beam生效,应如何定义UE行为。
基于上述问题,本申请提出了一种信道或信号重复传输的方案,在信道或信号的重复期间明确新的TCI状态是否生效,或者,在信道或信号的重复之后明确新的TCI状态的生效时间,能够保证终端与网络对波束理解的一致性。
以下通过具体实施例详述本申请的技术方案。

以下通过实施例1和实施例2详述本申请技术方案。
实施例1,第一TCI信息用于确定第一TCI状态,也即,在上述S230中,终端设备确定在第二时域位置之后是否应用第一TCI状态传输第一信道或信号。具体的,实施例1可以对应单TRP,以及第一信道或信号的传输次数为m。
在实施例1的一些实现方式中,若该第一信道或信号的m次传输的第一次传输的起始位置位于该第二时域位置之前,该终端设备确定该第一信道或信号的m次传输均应用第二TCI信息,其中,该第二TCI信息为该终端设备在该第二时域位置之前应用的TCI信息(假设为实施例1的方案1)。也即,终端设备不期望在m次传输的期间切换TCI状态。具体的,m次传输采用相同的TCI状态,即采用相同的波束(beam)发送该m次传输,从而,能够保持波束的一致性,两次相邻的传输之间的时间间隔可能不足够用来切换beam,避免因为切换波束带来的切换延迟。
在实施例1的一些实现方式中,若该第一信道或信号的m次传输中的前m 1次传输的起始位置位于该第二时域位置之前,且该第一信道或信号的m次传输中的后m-m 1次传输的起始位置位于该第二时域位置之后,该终端设备确定在该第二时域位置之后应用该第一TCI状态传输该第一信道或信号;其中,该第一信道或信号的m次传输中的前m 1次传输应用第二TCI信息,以及该第一信道或信号的m次传输中的后m-m 1次传输应用该第一TCI状态,该第二TCI信息为该终端设备在该第二时域位置之前应用的TCI信息,m和m 1均为正整数(假设为实施例1的方案2)。可选地,该第一信道或信号的第m 1次传输与第m 1+1次传输之间的时间间隔大于波束切换时间。由于采用统一的TCI状态机制,在第二时间位置之后,第一TCI信息会更新所有对应信道的波束,第一信道也采用第一TCI信息可以保持系统的波束一致性,可以避免与第二时间位置之后的其他信道的波束发生冲突。
在一些实施例中,波束切换时间的时间单位可以是符号,时隙,或者绝对时间等。具体的,对于单载波场景,波束切换时间可以采用载波配置的SCS,或者,波束切换时间可以采用激活BWP配置的子载波间隔,或者,波束切换时间可以采用初始BWP配置的子载波间隔。对于多载波的场景,波束切换时间可以采用多载波中配置的最小的SCS,或者,波束切换时间可以采用多载波的激活BWP中配置的最小的SCS,或者,波束切换时间可以采用多载波的初始BWP中配置的最小的SCS,或者, 波束切换时间可以采用多载波的初始BWP和激活BWP中配置的最小SCS。
在实施例1的一些实现方式中,若该第一信道或信号的m次传输中的前m 1次传输的起始位置位于该第二时域位置之前,且该第一信道或信号的m次传输中的后m-m 1次传输的起始位置位于该第二时域位置之后,该终端设备确定丢弃位于该第二时域位置之后的该第一信道或信号的后m-m 1次传输;其中,该第一信道或信号的m次传输中的前m 1次传输应用第二TCI信息,该第二TCI信息为该终端设备在该第二时域位置之前应用的TCI信息,m和m 1均为正整数(假设为实施例1的方案3)。从而,可以避免波束冲突,也可以避免因不满足波束切换时间而无法切换的问题。
需要说明的是,在本申请实施例中,“丢弃”可以替换为“不发送”。
在实施例1的一些实现方式中,若该第一信道或信号的m次传输中的前m 1次传输的起始位置位于该第二时域位置之前,该第一信道或信号的m次传输中的后m-m 1次传输的起始位置位于该第二时域位置之后,该终端设备确定将该第一TCI状态的应用时间延迟到该第一信道或信号的后m-m 1次传输结束,或者,该终端设备确定将该第一TCI状态的应用时间延迟到该第一信道或信号的传输结束后的第一个时间单元;其中,该第一信道或信号的m次传输中的前m 1次传输应用第二TCI信息,该第二TCI信息为该终端设备在该第二时域位置之前应用的TCI信息,m和m 1均为正整数(假设为实施例1的方案4)。从而,可以避免波束冲突。
具体例如,如图6所示,第一TCI信息通过PDCCH中的DCI承载,且第一TCI信息用于确定第一TCI状态。如图6中的A所示,第一信道或信号为PUSCH,且PUSCH在时域上至少传输4次,PUSCH1的起始位置位于第二时域位置之前,PUSCH2、PUSCH3和PUSCH4的起始位置位于第二时域位置之后,终端设备可以基于上述实施例1的方案确定在第二时域位置之后是否应用第一TCI状态传输PUSCH,或者,终端设备可以基于上述实施例1的方案确定在第二时域位置之后是否应用第一TCI状态对应的波束传输PUSCH。如图6中的B所示,第一信道或信号为PUCCH,且PUCCH在时域上至少传输4次,PUCCH1的起始位置位于第二时域位置之前,PUCCH2、PUCCH3和PUCCH4的起始位置位于第二时域位置之后,终端设备可以基于上述实施例1的方案确定在第二时域位置之后是否应用第一TCI状态传输PUCCH,或者,终端设备可以基于上述实施例1的方案确定在第二时域位置之后是否应用第一TCI状态对应的波束传输PUCCH。如图6中的C所示,第一信道或信号为PDSCH,且PDSCH在时域上至少传输4次,PDSCH1的起始位置位于第二时域位置之前,PDSCH2、PDSCH3和PDSCH4的起始位置位于第二时域位置之后,终端设备可以基于上述实施例1的方案确定在第二时域位置之后是否应用第一TCI状态传输PDSCH,或者,终端设备可以基于上述实施例1的方案确定在第二时域位置之后是否应用第一TCI状态对应的波束传输PDSCH。
具体的,在实施例1中,终端设备确定用哪个方案是基于网络设备配置的实施例1的方案1至方案4中的一种或多种确定的,或者是协议约定的,或者是根据终端设备的能力来确定的,或者是根据终端设备的能力+网络设备配置的实施例1的方案1至方案4中的一种或多种确定的。换句话说,网络设备可以配置使用实施例1的方案1至方案4中的某个方案,或者,网络设备可以基于终端设备的能力配置使用实施例1的方案1至方案4中的某个方案,或者,网络设备可以基于协议约定使用实施例1的方案1至方案4中的某个方案。
实施例2,第一TCI信息用于确定第二TCI状态和第三TCI状态,也即,在上述S230中,终端设备确定在第三时域位置之后是否应用第二TCI状态传输第一信道或信号,以及在第四时域位置之后是否应用第三TCI状态传输第一信道或信号。具体的,实施例2可以对应多TRP,第二时间间隔关联第一空间参数,第三时间间隔关联第二空间参数,以及第一信道或信号的传输次数为m。
在实施例2的一些实现方式中,若第一信道或信号的m次传输中的第一次传输的起始位置早于第三时域位置和第四时域位置中在时域上较早的时域位置,终端设备确定第一信道或信号的m次传输均应用第二TCI信息;其中,第二TCI信息为终端设备在第三时域位置和第四时域位置中在时域上较早的时域位置之前应用的TCI信息,m为正整数(假设为实施例2的方案1)。具体的,不区分与不同空间参数关联的传输,采用统一的机制来确定m次传输的TCI,实现比较简单。
在实施例2的一些实现方式中,若第一信道或信号的m次传输中与第一空间参数关联的第一次传输在第三时域位置之前,终端设备确定第一信道或信号的m次传输均应用第二TCI信息;或者,若第一信道或信号的m次传输中与第二空间参数关联的第一次传输在第四时域位置之前,终端设备确定第一信道或信号的m次传输均应用第二TCI信息;其中,第二TCI信息为终端设备在第三时域位置和第四时域位置中在时域上较早的时域位置之前应用的TCI信息,m为正整数(假设为实施例2的方案2)。具体的,m次传输采用相同的TCI state,即采用相同的波束(beam)发送m次传输,能够保持波束的一致性,两次相邻的传输之间的时间间隔可能不足够用来切换beam,避免因为切换波束带来的切换延迟。
也即,第一信道或信号的m次传输中与第一空间参数和第二空间参数关联的传输分别确定TCI状态。具体的,若第一信道或信号的m次传输与第一空间参数关联的第一次传输在第三时域位置之前,则与第一空间参数关联的m次传输中的所有传输应用第二TCI信息,即第一空间参数不发生更新。若第一信道或信号的m次传输与第二空间参数关联的第一次传输在第四时域位置之前,则与第二空间参数关联的m次传输中的所有传输应用第二TCI信息,即第二空间参数不发生更新。
在实施例2的一些实现方式中,终端设备确定第一信道或信号的m次传输中位于第三时域位置之后且与第一空间参数关联的传输应用第二TCI状态,以及第一信道或信号的m次传输中位于第四时域位置之后且与第二空间参数关联的传输应用第三TCI状态(假设为实施例2的方案3)。可选地,与相同空间参数关联的相邻两次传输之间的时间间隔大于波束切换时间。由于采用统一的TCI状态机制,不同空间参数对应的时域位置之后,第一TCI信息会更新所有对应信道的波束,第一信道或信号也采用第一TCI信息,可以保持系统的波束一致性,可以避免与其他信道的波束发生冲突。
在实施例2的一些实现方式中,终端设备确定丢弃第一信道或信号的m次传输中位于第三时域位置之后且与第一空间参数关联的传输,以及丢弃第一信道或信号的m次传输中位于第四时域位置之后且与第二空间参数关联的传输(假设为实施例2的方案4)。从而,可以避免波束冲突,也可以避免因不满足波束切换时间而无法切换的问题。
在实施例2的一些实现方式中,终端设备确定将第二TCI状态和第三TCI状态的应用时间延迟到第一信道或信号的m次传输结束(假设为实施例2的方案5)。
在实施例2的一些实现方式中,终端设备确定将第二TCI状态的应用时间延迟到第一信道或信号的m次传输中与第一空间参数关联的传输结束,或者,终端设备确定将第二TCI状态的应用时间延迟到第一信道或信号的m次传输中与第一空间参数关联的传输结束后的第一个时间单元;以及终端设备确定将第三TCI状态的应用时间延迟到第一信道或信号的m次传输中与第二空间参数关联的传输结束,或者,终端设备确定将第三TCI状态的应用时间延迟到第一信道或信号的m次传输中与第二空间参数关联的传输结束后的第一个时间单元(假设为实施例2的方案6)。
具体例如,如图7所示,第一TCI信息通过PDCCH中的DCI承载,且第一TCI信息用于确定第二TCI状态和第三TCI状态,第二时间间隔关联第一空间参数,第三时间间隔关联第二空间参数。如图7所示,第一信道或信号为PUSCH,且PUSCH在时域上至少传输4次,PUSCH1的起始位置位于第三时域位置之前,PUSCH2和PUSCH3的起始位置位于第三时域位置之后,且PUSCH2和PUSCH3的起始位置位于第四时域位置之前,PUSCH4的起始位置位于第四时域位置之后,终端设备可以基于上述实施例2的方案确定在第三时域位置之后是否应用第二TCI状态传输PUSCH,以及在第四时域位置之后是否应用第三TCI状态传输PUSCH,或者,终端设备可以基于上述实施例2的方案确定在第三时域位置之后是否应用第二TCI状态对应的波束传输PUSCH,以及在第四时域位置之后是否应用第三TCI状态对应的波束传输PUSCH。
具体的,在实施例2中,终端设备确定用哪个方案是基于网络设备配置的实施例2的方案1至方案6中的一种或多种确定的,或者是协议约定的,或者是根据终端设备的能力来确定的,或者是根据终端设备的能力+网络设备配置的实施例2的方案1至方案6中的一种或多种确定的。换句话说,网络设备可以配置使用实施例2的方案1至方案6中的某个方案,或者,网络设备可以基于终端设备的能力配置使用实施例2的方案1至方案6中的某个方案,或者,网络设备可以基于协议约定使用实施例2的方案1至方案6中的某个方案。
在一些实施例中,第二TCI信息是通过DCI指示的,或者是MAC CE激活的。
在一些实施例中,第二TCI信息是根据默认规则确定的,默认规则包括:
与终端设备初始接入的SSB具体QCL关联的TCI state,例如,第一信道或信号为PDSCH的DMRS,或第一信道或信号为PDCCH的DMRS,或第一信道或信号为CSI-RS等;
与终端设备随机接入的SSB或CSI-RS具体QCL关系的TCI state,例如,第一信道或信号为PDSCH的DMRS,或第一信道或信号为PDCCH的DMRS,或第一信道或信号为CSI-RS等;

因此,在本申请实施例中,在第一TCI信息用于确定第一TCI状态的情况下,终端设备确定在第二时域位置之后是否应用第一TCI状态传输第一信道或信号,通过明确在第二时域位置之后是否应用第一TCI状态传输第一信道或信号,从而可以保证终端与网络对波束理解的一致性。或者,在第一TCI信息用于确定第二TCI状态和第三TCI状态的情况下,终端设备确定在第三时域位置之后是否应用第二TCI状态传输第一信道或信号,以及在第四时域位置之后是否应用第三TCI状态传输第一信道 或信号,通过明确在第三时域位置之后是否应用第二TCI状态传输第一信道或信号,以及在第四时域位置之后是否应用第三TCI状态传输第一信道或信号,从而可以保证终端与网络对波束理解的一致性。
