为使本领域技术人员能够更好地理解本申请实施例,先进行如下说明。
一、关于波束指示(beam indication)机制:
在经过波束测量和波束报告后,网络可以对下行与上行链路的信道或参考信号做波束指示,用于网络与终端UE之间建立波束链路,实现信道或参考信号的传输。
1、对于物理下行控制信道(Physical Downlink Control Channel,PDCCH)的波束指示,网络使用无线资源控制(Radio Resource Control,RRC)信令为每个控制资源集(Control Resource Set CORESET)配置K个传输配置指示状态(Transmission Configuration Indication state,TCI state),当K>1时,由媒体接入层控制单元(Medium Access Control Element,MAC CE)指示或激活1个TCI state,当K=1时,不需要额外的MAC CE命令。UE在监听PDCCH时,对CORESET内全部搜索空间(Search Space)使用相同的准共 址(Quasi-Colocation,QCL),即使用相同的TCI state来监听PDCCH。该TCI state中的参考信号(Reference Signal,RS),例如周期信道状态信息参考信号资源(Channel State Information Reference Signal resource,CSI-RS)、半持续CSI-RS资源、同步信号(Synchronic Signal Block,SSB)等,与终端物理下行控制信道特定解调参考信号(Physical Downlink Control Channel-specific Demodulation Reference Signal,UE-specific PDCCH DMRS)端口是空间QCL的。UE根据该TCI state即可获知使用哪个接收波束来接收PDCCH。
2、对于物理下行共享信道(Physical Downlink shared Channel,PDSCH)的波束指示,网络通过RRC信令配置M个TCI state,再使用MAC CE命令激活2N个TCI state,然后通过下行控制信息(Downlink Control Information,DCI)的N个TCI位域(N-bit TCI field)来通知TCI state,该TCI state中的参考信号与要调度的PDSCH的解调参考信号(Demodulation Reference Signal,DMRS)端口是QCL的。UE根据该TCI state即可获知使用哪个接收波束来接收PDSCH。
3、对于信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)的波束指示,当CSI-RS类型为周期CSI-RS时,网络通过RRC信令为CSI-RS资源配置QCL信息。当CSI-RS类型为半持续CSI-RS时,网络通过MAC CE命令来从RRC配置的CSI-RS资源集中激活一个CSI-RS resource时指示其QCL信息。当CSI-RS类型为非周期CSI-RS时,网络通过RRC信令为CSI-RS资源配置QCL,并使用DCI来触发CSI-RS。
4、对于物理上行控制信道(Physical Uplink Control Channel,PUCCH)的波束指示,网络使用RRC信令通过物理上行控制信道空间关系信息(PUCCH-Spatial RelationInfo)为每个PUCCH资源配置空间关系信息,当为PUCCH资源配置的空间关系信息包含多个时,使用MAC-CE指示或激活其中一个参数空间关系信息。当为PUCCH资源配置的空间关系信息只包含1个时,不需要额外的MACCE命令。
5、对于PUSCH(Physical Uplink shared Channel物理上行共享信道)的波束指示,PUSCH的空间关系信息是当PDCCH承载的DCI调度PUSCH时, DCI中的上行调度请求指示域(Scheduling Request Indication field,SRI field)的每个SRI位点(code point)指示一个SRI,该SRI用于指示PUSCH的空间关系信息。
6、对于信道探测参考信号(Sounding Reference Signal,SRS)的波束指示,当SRS类型为周期SRS时,网络通过RRC信令为SRS资源配置空间关系信息。当SRS类型为半持续SRS时,网络通过MAC CE命令来从RRC配置的一组空间关系信息中激活一个。当SRS类型为非周期SRS时,网络通过RRC信令为SRS资源配置空间关系信息,还可以使用MAC CE命令更新非周期SRS资源的空间关系信息。
二、关于多传输接收点(multi-Transmission Reception Point,multi-TRP)场景中的波束指示:
在3GPP版本16中引入了multi-TRP场景,根据控制信息的发送方式,可以区分为DCI单发送和DCI多发送,前者是在一个TRP发送DCI来调度多个TRP上的数据传输,后者是允许在多个TRP发送DCI来分别调度在各自TRP上的数据传输。
在DCI调度PDSCH时,当DCI与PDSCH之间的调度间隔(scheduling offset or time offset)小于或等于预设门限时,需要使用默认波束来传输PDSCH。现有技术中规定如下:
1、对于基于多传输接收点或天线(multi-Transmission Reception Point/multi-Transmission Reception Panel)的DCI多发送,如果配置了控制资源集池索引(CORESET Pool Index),当上述调度间隔小于或等于预设门限时,则UE假设PDSCH DMRS端口与配置了相同控制资源集池索引值的控制资源集池索引最低值(CORESET with lowest index)的PDCCH的QCL信息中的参考信息是QCL的
上述的CORESET with lowest index是在最近时隙(latest slot)中与各自CORESET Pool Index值对应的需UE监听的CORESET中的CORESET with lowest index。其中,latest slot是指在服务小区激活宽带部分(Bandwidth Part,BWP),中存在至少一个关联了相应CORESET Pool Index的CORESET的时隙。
如果UE不支持该特性,则无论CORESET Pool Index怎样配置,都重用3GPP版本15的规则,即CORESET with lowest index是在latest slot中需UE监听的CORESET中的CORESET with lowest index,而与CORESET Pool Index无关。
2、对于基于单传输接收点或天线(single-single-Transmission Reception Point/single-Transmission Reception Panel)的DCI单发送,当上述调度间隔小于或等于预设门限时,且接收到UE特定PDSCH的TCI状态的激活命令之后,则UE假设PDSCH DMRS端口使用预设TCI状态的QCL参数。即,在用于PDSCH的激活的TCI状态中,从包含2个不同TCI状态的TCI码位中选择最低码位(lowest code point)对应的TCI状态。
如果所有的TCI码位都对应单个TCI状态,则使用Release 15的规则。
需要说明的是,所提及的波束信息,也可以称为:空间关系(spatial relation)信息、空域发送滤波器(spatial domain transmission filter)信息、空域滤波器(spatial filter)信息、传输配置指示状态(TCI state)信息、准共址(QCL)信息或QCL参数等。其中,下行波束信息通常可使用TCI state信息或QCL信息表示。上行波束信息通常可使用spatial relation信息表示。
所提及的天线面板,也可以称为:天线组、天线端口组、天线集合、天线端口集合、波束集合、波束子集合、天线阵列、天线端口阵列、天线子阵列、天线端口子阵列、逻辑实体、实体或天线实体等。
Panel的标识可以为:天线面板的标识、参考信号资源标识、参考信号资源集标识、TCI状态标识、QCL信息标识、空间关系标识等。
