Description

信道信息的确定方法、网络设备及终端设备 技术领域
本申请涉及通信领域,尤其涉及一种信道信息的确定方法、网络设备及终端设备。
背景技术
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)对新无线(New radio,NR)通信系统的标准制定过程中,将系统支持的工作频段提升至6GHz以上。高频段具有较为丰富的空闲频率资源,可以为数据传输提供更大的吞吐量。高频信号的波长短与同低频段相比,能够在同样大小的面板上布置更多的天线阵元,利用波束赋形技术形成指向性更强、波瓣更窄的波束。
模拟波束赋形是全带宽发射的,并且每个高频天线阵列的面板上的每个极化方向阵元仅能以时分复用的方式发送模拟波束。模拟波束的赋形权值通过调整射频前端移相器等设备的参数来实现。
目前在学术界和工业界,通常是使用轮询的方式进行模拟波束赋形向量的训练,即每个天线面板的每个极化方向的阵元以时分复用方式依次在约定时间发送训练信号(即候选的赋形向量),终端经过测量后反馈波束报告,供网络侧在下一次传输业务时采用该训练信号来实现模拟波束发射。波束报告的内容通常包括最优的若干个发射波束标识以及测量出的每个发射波束的接收功率。
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,用于网络与终端之间建立波束链路,实现信道或参考信号的传输。现有技术中,按照以下方式进行波束指示:
对于物理下行控制信道(Physical Downlink Control Channe,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(Transmission Configuration Indication,TCI)状态(state),当K>1时,由媒体访问控制(Media Access Control,MAC)控制单元(CE)指示或激活1个TCI state,当K=1时,不需要额外的MAC CE命令。终端设备(User Equipment,UE)在监听PDCCH时,对CORESET内的全部搜索空间使用相同的准共址(Quasi-colocation,QCL),即相同的TCI state来监听PDCCH。该TCI状态中的参考信号(reference Signal,RS)与UE特定的PDCCH解调参考信号(DemodulationReference Sgnal,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。
对于物理下行共享信道(Physical Downlink Shared Channel,PDSCH)的波束指示,网络通过无线资源控制协议(Radio Resource Control,RRC)信令配置M个TCI state,再使用MAC CE命令激活2 N个TCI state,然后通过下行控制信息(Downlink Control Information,DCI)N-bit TCI字段来通知TCI state,该TCI state中的RS与要调度的PDSCH的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。
对于信道状态信息参考信号(Channel State Information-Reference Signals,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 resource set中激活一个CSI-RS资源时指示其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。
对于物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH)的波束指示,网络使用RRC信令通过参数PUCCH-SpetialRelationInfo为每个PUCCH资源配置空间关系信息(spatial relation information),当为PUCCH资源配置的spatial relation information包含多个时,使用MAC CE指示或激活其中一个spatial relation information。当为PUCCH资源配置的spatial relation information只包含1个时,不需要额外的MAC CE命令。
对于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的波束指示,PUSCH 的spatial relation information是当PDCCH承载的DCI调度PUSCH时,DCI中的资源指示信息(resource indicater SRS,SRI)字段的每个SRI代码点指示一个SRI,该SRI用于指示PUSCH的spatial relation information。
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spatial relation information。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spatial relation information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spatial relation information。
可见,现有技术中对信道信息的配置或指示方式并不完善,其不适用于一些多成员载波(Component Carrier,CC)、多带宽部分(Bandwidth Part,BWP)或多发送接收点(transmit Reception Point,TRP)的场景。

在一个实施例中,参数信息包括PL RS;预设条件包括未配置PUCCH或SRS资源集的PL RS。
本实施例中,第一信道包括PUCCH,第一RS包括SRS资源集。网络设备利用MAC CE命令从多个DL RS中指示一个DL RS。基于此,终端设备确定第二RS的PL RS即为MAC CE命令从多个DL RS中所指示的DL RS。这种情况下,终端设备接收到的MAC CE命令中可携带有所指示的DL RS的标识信息。当然,MAC CE命令中携带的信息内容并不局限于此。

可选地,第一信道与第一关联信道对应相同的CORESET信息和/或TRP信息;第一RS与第一关联RS对应相同的CORESET信息和/或TRP信息。
此外,多TRP场景可与其他任一预设条件相结合。即,预设条件包括多TRP场景的情况下,还可包括其它至少一个场景。以下通过具体实施例来说明多TRP场景与其它预设条件结合的场景。
例如,预设条件包括多CC场景下配置了多个PUCCH资源,且为多TRP场景。第一信道与第一关联信道对应相同的TRP信息;第一RS与第一关联RS对应相同的TRP信息。MAC CE命令中携带有TRP信息,假设MAC CE命令中携带的TRP信息用于指示第一信道或第一RS对应的TRP为TRP1。由上述实施例可知,在多CC场景下配置了多个PUCCH资源的情况下,网络设备可利用MAC CE命令更新、激活或指示第一CC列表中的第一CC的第二BWP上的第二PUCCH资源的空间关系信息为第二空间关系信息,由于第一信道或第一RS对应的TRP为TRP1,因此终端设备可确定第一CC列表中的全部CC的全部BWP上对应TRP1的全部PUCCH资源的空间关系信息为第二空间关系信息。即,终端设备确定第二信道(或第一关联信道)或第二RS(或第二关联RS)的空间关系信息时,针对的是与第一信道或第一RS对应的同一TRP内的空间关系信息。
再例如,预设条件包括多CC场景下配置了多个PUCCH资源组,且为多TRP场景。第一信道与第一关联信道对应相同的TRP信息;第一RS与第一关联RS对应相同的TRP信息。MAC CE命令中携带有TRP信息,假设MAC CE命令中携带的TRP信息用于指示第一信道或第一RS对应的TRP为TRP2。由上述实施例可知,在多CC场景下配置了多个PUCCH资源组的情况下,网络设备可利用MAC CE命令更新、激活或指示第二CC列表中的第二CC的第三BWP上的第二PUCCH资源组中全部PUCCH资源的空间关系信息为第三空间关系信息,由于第一信道或第一RS对应的TRP为TRP2,因此终端设备可确定第二CC列表中的全部CC的全部BWP上对应TRP2的全部PUCCH资源的空间关系信息为第二空间关系信息。即,终端设备确定第二信道(或第一关联信道)或第二RS(或第二 关联RS)的空间关系信息时,针对的是与第一信道或第一RS对应的同一TRP内的空间关系信息。
以上列举了多TRP场景与其它两种预设条件结合的场景下,终端设备如何根据第一信道或第一RS的参数信息确定第二信道或第二RS的参数信息。需要说明的是,多TRP场景与其它任一预设条件结合的场景下,终端设备确定的对象均为与第一信道或第一RS所对应的同一TRP内的第二信道或第二RS参数信息。
此外,还需说明的是,上述任一实施例中提及的“标识”也可意指“索引”,本说明书实施例对此不作限定。例如,“PUCCH资源组标识”也可称之为“PUCCH资源组索引”;再例如,“SRS资源集标识”也可称之为“SRS资源集索引”;等等。
上述对本说明书特定实施例进行了描述。其它实施例在所附权利要求书的范围内。在一些情况下,在权利要求书中记载的动作或步骤可以按照不同于实施例中的顺序来执行并且仍然可以实现期望的结果。另外,在附图中描绘的过程不一定要求示出的特定顺序或者连续顺序才能实现期望的结果。在某些实施方式中,多任务处理和并行处理也是可以的或者可能是有利的。
