波束指示方法、网络侧设备和终端
相关申请的交叉引用
本申请主张在2020年05月27日在中国提交的中国专利申请号202010463308.5的优先权,其全部内容通过引用包含于此。
技术领域
本申请涉及通信领域,尤其涉及一种波束指示方法、网络侧设备和终端。
背景技术
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,用于网络与用户设备(User Equipment,UE)之间建立波束链路,实现信道或参考信号的传输。
在相关技术中,对于物理下行控制信道(Physical Downlink Control Channel,PDCCH)的波束指示,网络侧使用无线资源控制(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,由媒体接入控制(Media Access Control,MAC)控制单元(Control Element,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根据该TCI状态即可获知接收PDCCH的接收波束。对于PDSCH的波束指示,网络侧通过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-bit TCI field(域)来通知TCI状态。UE根据该TCI状态即可获知接收PDSCH的接收波束。对于信道状态信息参考信号(Channel-State Information reference Signal,CSI-RS)的波束指示,网络侧为终端配置或激活一个CSI-RS资源(resource)时,指示其准共址(Quasi-colocation,QCL)信息。UE根据该QCL信息即可获知接收CSI-RS的接收波束。对于物理上行控制信道(Physical Uplink Control Channel,PUCCH)的波束指示,网络侧使用RRC信令为每个PUCCH resource配置空间关系信息(spatial relation information),若为PUCCH resource配置的空间关系信息包含多个,则使用MAC-CE指示或激活其中一个空间关系信息。UE根据该空间关系信息即可获知PUCCH的发射波束。对于物理上行共享信息(Physical Uplink Shared Channel,PUSCH)的波束指示,PUSCH的spatial relation信息是当PDCCH承载的DCI调度PUSCH时,DCI中指示一个探测参考信号资源指示(Sounding Reference Signal Resource Indicator,SRI),该SRI用于指示PUSCH的空间关系信息。UE根据该空间关系信息即可获知PUSCH的发射波束。对于探测参考信号(Sounding Reference Signal,SRS)的波束指示,当SRS类型为周期SRS时,网络侧为SRS resource配置、激活或更新一个spatial relation information。UE根据该空间关系信息即可获知SRS的发射波束。
而在multi-TRP(多传输节点)场景中,根据控制信息的发送方式,可以将波束指示分为单下行控制信息(single Downlink Control Information,single DCI)和多下行控制信息multi-DCI,前者是在一个TRP(传输节点)发送DCI来调度多个TRP上的数据传输,后者是在多个TRP发送DCI来分别调度在各自TRP上的数据传输。
由此可见,在相关技术中各种信道和参考信号的波束指示机制不相同,从而导致波束的指示信令开销较大。

下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的波束指示方法、网络侧设备和终端进行详细地说明。
图2为本申请实施例提供的波束指示方法的一种流程示意图,该方法可以由网络侧设备执行。换言之,所述方法200可以由安装在网络侧设备上的软件或硬件来执行。如图2所示,该方法可以包括以下步骤。
S201:使用指示信道,向目标终端指示多个目标对象的公共波束信息,其中,公共波束信息用于指示多个目标对象的波束信息,目标对象包括以下至少一项:目标信道和目标参考信号。
在本申请实施例中,目标信道包括但不限于:PDCCH、PDSCH、PUSCH以及PUCCH等;目标参 考信号包括但不限于:同步信号块(Synchronization Signal Block,SSB)、CSI-RS和SRS等。
对于高频通信系统来说,网络和终端之间的通信链路通常可以使用单波束方式,即控制信道、数据信道、参考信号等的波束方向基本一致,因此,在本申请实施例中,网络侧设备可以通过指示信道,向目标终端指示或更新后续的多个目标对象的波束信息,从而可以实现为多个目标对象指示统一的公共波束信息,降低波束指示的信令开销,并且可以较快的切换目标对象的波束信息,提高波束信息指示的灵活性。
需要说明的是,在本申请的一个可能的实现方式中,指示信道可以为预先约定的信道,也可以为网络配置的信道。
在一个可能的实现方式中,在所述指示信道上,可以采用预定格式的DCI指示所述公共波束信息。因此,上述S201可以包括:使用指示信道,发送预设格式的DCI指示多个目标对象的公共波束信息,其中,预定格式的DCI包括用于指示公共波束信息的信令域。
其中,预定格式的DCI可以包括以下任一项:
(1)物理下行控制信道(Physical Downlink Control Channel,PDCCH)所承载的DCI;例如,可以使用调度信道或参考信号传输时的任意DCI format(格式)中的波束指示信息指示所述公共波束信息,例如,DCI format 1_1或DCI format 0_1。
(2)用于调度数据信道传输的DCI;即该DCI可以为PDCCH所承载的特定DCI format,例如,可以使用调度下行共享物理信道(Physical Downlink Shared Channel,PDSCH)的DCI format 1_1中的波束指示信息指示所述公共波束信息。
(3)专用于指示公共波束信息的DCI。即专用于传输所述公共波束信息的DCI格式,该DCI包括用于指示公共波束信息的信令域。
在一个可能的实现方式中,公共波束信息可以包括但不限于以下任一项:公共的传输配置指示(Transmission Configuration Indication,TCI)状态信息、公共的准共址(Quasi-colocation,QCL)信息和公共的空间关系(spatial relation)信息。即多个目标对象的波束信息是公共的TCI状态信息、公共的QCL信息、或公共的空间关系信息。
可能地,指示信道可以在预设的控制资源集(CORESET)上传输,也可以在预设控制资源集之外的控制资源集上传输。例如,指示信道可以在CORESET标识为最小的CORESET上传输,或者在CORESET标识为最小的CORESET之外的其他CORESET上传输。也可以只在CORESET#0(即CORESET标识为最小的CORESET)上传输,或者在除CORESET#0之外的其他CORESET上传输。
在一个可能的实现方式中,指示信道可以使用组公共PDCCH,也可以使用专用PDCCH。即指示信道可以为一组终端的组公共PDCCH,也可以为一个终端的专用PDCCH。
因此,在一个可能的实现方式中,所述指示信道可以包括:第一组公共PDCCH(group common PDCCH),S201可以包括:在第一组公共PDCCH上,指示至少一个终端的公共波束信息,其中,至少一个终端包括目标终端。在该可能的实现方式中,网络侧设备可以在第一组公共PDCCH上,按照预设位置或预设顺序承载所述至少一个终端中各个终端的公共波束信息。即网络侧设备在第一个组公共PDCCH上指示至少一个终端的公共波束信息,该至少一个终端中的各个终端的公共波束信息,在第一组公共PDCCH上按照预设位置或预设顺序排列。
在一个可能的实现方式中,为了使至少一个终端中的各个终端可以获知第一组PDCCH的信息,在S201之前,该波束指示方法还可以包括:为所述至少一个终端配置第一组公共PDCCH的信息,或向所述至少一个终端指示第一组公共PDCCH的信息。所述至少一个终端中各个终端根据配置或指示的第一组公共PDCCH的信息,可以确定第一组公共PDCCH,至少一个终端监听该组PDCCH。
在另一个可能的实现方式中,为了使至少一个终端中各个终端能够获知各个终端的公共波束信息在第一组公共PDCCH上的位置或顺序,在第一组公共PDCCH上,指示至少一个终端的公共波束信息之前,该波束指示方法还可以包括:向所述至少一个终端发送第一指示信息,第一指示信息指示所述至少一个终端中各个终端的公共波束信息在第一组公共PDCCH上的预定位置或预定顺序。通过该第一指示 信息,至少一个终端中的各个终端可以获知其公共波束信息在第一组公共PDCCH上的位置或顺序。
在上述可能的实现方式中,在为至少一个终端配置第一组公共PDCCH之后,其中某个终端的状态可能发生变化,例如,某个终端的位置移动(如达到一定的位移)或旋转(如达到一定的角度)等,则可以改为使用其它的组公共PDCCH传输该终端的公共波束信息。因此,该波束指示方法还可以包括:若至少一个终端中的第一终端的状态发生变化,则使用第二组公共PDCCH指示第一终端的公共波束信息,其中,第二组公共PDCCH为第一组公共PDCCH之外的组公共PDCCH。
在上述可能的实现方式中,网络侧设备还可以为第一终端重配置或指示第二组公共PDCCH的信息,以使第一终端可以获知并监听第二组公共PDCCH。其中第二组公共PDCCH可以为第一终端与其它终端(可能不包含所述至少一个终端中状态未发生改变的终端)共用的,即第一终端与其它终端为一组终端。
可以理解的是,第二组公共PDCCH可以是网络侧设备在第一终端发生变化前配置的,也就可以是在检测到第一终端发生变化后配置的,本申请实施例中不做具体限定。
在一个可能的实现方式中,上述配置或指示的组公共PDCCH的信息中可以包括group common PDCCH的TCI state信息。则所述第一终端可以使用所述重配置或指示的group common PDCCH(即第二组公共PDCCH)的信息中的TCI state信息,监听所述group common PDCCH(即第二组公共PDCCH);而所述至少一个终端中状态未发生变化的终端,则监听原组公共PDCCH(即第一组公共PDCCH)。而网络侧设备分别发送第一组公共PDCCH和第二组公共PDCCH。
在另一个可能的实现方式中,在为至少一个终端配置第一组公共PDCCH的信息,或向至少一个终端指示第一组公共PDCCH的信息之后,若至少一个终端中的第一终端的状态发生变化,该波束指示方法还可以包括:使用第一波束信息发送第一组公共PDCCH,指示第一终端的公共波束信息,其中,第一波束信息与第二波束信息不同,第二波束信息为在第一终端的状态发生变化前传输的第一组公共PDCCH的波束信息。也就是说,在该可能的实现方式中,网络侧重配置或指示第一组公共PDCCH的波束信息(即第一波束信息),网络侧利用第一波束信息发送第一组公共PDCCH,通过利用第一波束信息发送的第一组公共PDCCH,指示状态发生变化的第一终端的公共波束信息,而利用原波束信息(即第二波束信息)发送的第一组公共PDCCH指示未发生状态变化的其它终端的公共波束信息。
可以理解的是,第一波束信息可以是网络侧设备在第一终端发生变化前配置或指示的,也就可以是在检测到第一终端状态发生变化后配置或指示的,本申请实施例中不做具体限定。
可选地,上述第二组公共PDCCH或第一波束信息可以通过以下任一项确定:第一终端当前所用的上行反馈资源;第一终端发送指示信道的反馈信息所用的上行反馈资源;第一终端发送的波束报告;第一终端发送上行信道使用的波束信息;第一终端发送的物理随机接入信道(Physical Random Access Channel,PRACH)资源。
可选地,可以预先设置的UE所用的上行反馈资源与组公共PDCCH或组公共PDCCH的波束信息的对应关系,则可以根据第一终端当前所使用的上行反馈资源或第一终端反馈指示信道的反馈信息所用的上行反馈资源,确定第二组公共PDCCH或第一波束信息。
在上述可能的实现方式中,由于第一终端的状态发生变化,则第一组公共PDCCH上承载的公共波束信息的位置或顺序可能发生改变,因此,该波束指示方法还可以包括:向所述至少一个终端发送第二指示信息,其中,所述第二指示信息用于更新至少一个终端中各个终端的公共波束信息在第一组公共PDCCH或者第二组公共PDCCH上的预设位置或预设顺序。也就是说,当至少一个终端中的某个终端的状态发生变化,网络侧设备可以通过第二指示信息指示或更新各个终端的公共波束信息在第一公共组PDCCH或第二公共组PDCCH的位置或承载顺序。
在另一个可能的实现方式中,指示信道也可以使用专用PDCCH,即各个终端专用的PDCCH。因此,在上述S201,可以执行如下内容:在专用PDCCH上的DCI中的公共波束信息信令域中携带公共波束信息。
在一个可能的实现方式中,为了使网络侧设备可以获知目标终端是否成功的接收到所述公共波束信 息,目标终端可以向网络侧设备发送反馈信息。因此,在该可能的实施例中,在S201之后,该波束指示方法还可以包括:接收目标终端针对所述公共波束信息的第一反馈信息。
在上述可能的实现方式中,可选地,在接收目标终端针对公共波束信息的第一反馈信息之后,该方法还可以包括:若第一反馈信息为确认信息,则使用所述公共波束信息,向目标终端传输目标对象;若第一反馈信息为非确认信息,则使用目标对象当前使用的波束信息,向目标终端传输目标对象。
可选地,在本申请另一个可能的实施例中,在S201之后,该波束指示方法还可以包括:若在预定时间内未接收到目标终端针对公共波束信息的第一反馈信息,则使用目标对象当前使用的波束信息,或者使用指示的公共波束信息和目标对象当前使用的波束信息传输目标对象,向目标终端传输目标对象。也就是,网络侧设备在向目标终端指示公共波束信息后,有可能接收不到第一反馈信息(可能是目标终端未接收到公共波束信息,因此未发送第一反馈信息,也可能是第一反馈信息(例如,ACK或NACK)在传输过程中丢失),则网络侧设备在后续可以仍使用目标对象当前使用的波束信息(即原波束信息)传输目标对象,也可以使用指示的公共波束信息和目标对象当前使用的波束信息传输目标对象,以确保目标终端可以正确传输目标对象。
在上述可能的实现方式中,目标终端发送第一反馈信息的资源可以是预先约定地,也可以是网络侧设备,分配或指示的上行反馈资源。因此,在一个可能的实现方式中,该波束指示方法还可以包括:为目标终端分配发送第一反馈信息的资源,并根据该资源接收所述第一反馈信息。例如,网络侧设备可以预先为目标终端分配上行反馈资源,并在该上行反馈资源上监听目标终端反馈的第一反馈信息。
在另一个可能的实现方式中,也可以不使用反馈机制,则在S201之后,该波束指示方法还可以包括:使用公共波束信息和目标对象当前使用的波束信息,向目标终端传输目标对象。即在该可能的实现方式中,终端在接收到公共波束信息之后,并不对是否成功接收到该公共波束信息进行反馈,在这种情况下,在后续的传输过程中,网络侧设备同时在公共波束信息和目标对象当前使用的波束信息,向目标终端传输目标对象。通过该可能的实现方式,可以减少上行资源的占用。
在另一个可能的实现方式中,在不使用反馈机制的情况下,也可以将CORESET分组,在该可能的实现方式中,该波束指示方法还可以包括:将第三波束信息确定为第一CORESET组中各CORESET的波束信息,将第四波束信息确定为第二CORESET组中各CORESET的波束信息。
在上述可能的实现方式中,可选地,可以将CORESET标识最小的CORESET和其它CORESET分成两组,即第一CORESET组包括CORESET标识最小的CORESET(例如,CORESET#0),第二CORESET组包括除CORESET标识最小的CORESET之外的CORESET(例如,除CORESET#0之外的其他CORESET)。
在上述可能的实现方式中,可选地,在将第三波束信息确定为第一CORESET组中各CORESET的波束信息,将第四波束信息确定为第二CORESET组中各CORESET的波束信息之前,该波束指示方法还可以包括:向目标终端发送第三指示信息,其中,第三指示信息用于指示第三波束信息和/或第四波束信息。即在该可能的实现方式中,第三指示信息可以用于指示其中一组CORESET的波束信息,也可以同时指示两组CORESET的波束信息。在实际应用中,可以通过指示信道发送第三指示信息,也可以通过媒体接入控制层(Medium Access Control,MAC)控制单元(Control Element,CE)命令发送所述第三指示信息。
其中,第三指示信息可以包括:第一CORESET组的组标识与第三波束信息,和/或,第二CORESET组的组标识与第四波束信息。也就是说,在第三指示信息中可以显式的指示各个波束信息对应的CORESET组;或者,第三指示信息中第三波束信息和/或第四波束信息按预设位置或预设顺序排列,即在第三指示信息中并不显式的指示各个波束信息对应的CORESET组,而是按照预设位置或预设顺序排列第三波束信息和/或第四波束信息。
在上述可能的实现方式中,指示信道可以在不同的CORESET组中的一个或多个CORESET组中传输。即所述指示信道可以在所述第一CORESET组和/或第二CORESET组上传输,则在第三波束信息和第四波束信息中,一个为指示信道当前使用的波束信息,另一个为指示信道指示的或MAC CE命令 指示的指示信道的波束信息。从而,增强指示信道的传输可靠性和鲁棒性。
在上述可能的实现方式中,当某个目标对象为控制信道(例如PDCCH)时,该目标对象承载的DCI可以在不同的CORESET组中的一个或多个CORESET组中传输,即所述目标对象在所述第一CORESET组和/或第二CORESET组上传输,则第三波束信息和第四波束信息中,一个是目标对象当前使用的波束信息,另一个是指示信道指示的公共波束信息。从而,增强控制信令的传输可靠性和鲁棒性。
在上述可能的实现方式中,网络可以仅指示一个CORESET组的波束信息,则另一个CORESET组的波束信息仍为其当前使用的波束信息(即原波束信息)。
在上述的各个可能的实现方式中,多个目标对象可以包括所述指示信道,即指示信道所指示的公共波束信息,也是指示信道的波束信息。
或者,在上述各个可能的实现方式中,多个目标对象也可以不包括指示信道,即多个目标对象包括指示信道以外的信道和参考信号。
当上述多个目标对象包括指示信道以外的信道和参考信号时,在一个可能的实现方式中,指示信道还用于指示该指示信道的波束信息。也就是,指示信道不仅可以指示公共波束信息,还可以指示自己的波束信息。在该可能的实现方式中,所述指示信道可以在特定的CORESET上传输,如CORESET#0或除CORESET#0以外的其它CORESET。
在上述可能的实现方式中,指示信道中可以包括:第一信令域和第二信令域,其中,第一信令域用于指示多个目标对象的公共波束信息,第二信令域用于指示该指示信道的波束信息。例如,指示信道中可以包括公共波束信息信令域和指示信道波束信息信令域,所述公共波束信息信令域用于指示所述其它信道和参考信号的波束信息;所述指示信道波束信息信令域用于指示所述指示信道的波束信息。
或者,也可以通过指示信道的格式或资源来指示所指示的波束信息所属的信道或参考信号,即使用不同格式或不同资源,分别用于指示所述指示信道的波束信息和多个所述目标对象的波束信息。例如,在一个可能的实现方式中,指示信道可以通过以下方式指示公共波束信息和指示该指示信道的波束信息:采用预先设置的第一指示信道格式指示该指示信道的波束信息,采用预先设置的第二指示信道格式指示多个目标对象的公共波束信息;或者采用预先设置的第一资源,指示该指示信道的波束信息,采用预先设置的第二资源,指示多个目标对象的公共波束信息。其中指示信道格式可以是DCI格式。
或者,也可以使用同一格式或同一资源,指示所述指示信道的波束信息和所述其它信道和参考信号的波束信息,即所述指示信道和所述其它信道和参考信号的波束信息相同。因此,在另一个可能的实现方式中,指示信道还可以通过以下方式指示公共波束信息和指示该指示信道的波束信息:采用预定格式的指示信道和/或在预定资源上传输指示信道,指示公共波束信息和指示信道的波束信息,其中,公共波束信息与指示信道的波束信息相同。
在上述可能的实现方式中,指示信道的波束信息可以为指示信道所在的CORESET的TCI状态信息。
在上述可能的实现方式中,若指示信道为第一组公共PDCCH,则第一组公共PDCCH指示的波束信息中,指示信道的波束信息与多个目标对象的公共波束信息不同。也就是说,若指示信道为第一组公共PDCCH,则在第一组公共PDCCH指示的波束信息中包括指示信道的波束信息和至少一个终端中各个终端的所述公共波束信息,
其中,指示信道的波束信息与多个目标对象的公共波束信息不同,可以是与所述至少一个终端中所有终端的公共波束信息均不相同,也可以是与所述至少一个终端的部分终端的公共波束信息不同。
在一个可能的实现方式中,在使用指示信道,指示该指示信道的波束信息之后,该波束指示方法还可以包括:接收目标终端针对指示信道的波束信息的第二反馈信息,若第二反馈信息为确认信息,则使用指示的指示信道的波束信息,向目标终端传输指示信道;若第二反馈信息为非确认信息,则使用指示信道当前的波束信息。
在实际应用中,还可能未接收到第二反馈信息,例如,目标终端未接收到所述指示信息的波束信息,因此,未反馈所述第二反馈信息,或者,目标终端反馈了所述第二反馈信息(可能为ACK,也可能为 NACK),但在传输过程中丢失,从而导致未接收到。因此,在一个可能的实现方式中,该方法还可以若在预设时间内未接收到第二反馈信息,则使用所述指示信道当前的波束信息,向所述目标终端传输所述指示信道,或者,使用指示的指示信道的波束信息和指示信道当前的波束信息,向目标终端传输指示信道。
在本申请实施例中,目标终端可以针对指示的指示信道的波束信息和公共波束信息分别发送反馈信息,即第一反馈信息和第二反馈信息,或者,目标终端也可以针对指示的指示信道的波束信息和公共波束信息,统一发送一个反馈信息,即第一反馈信息和第二反馈信息为同一反馈信息,该反馈信息同时指示目标终端是否成功接收指示信道的波束信息和公共波束信息,如果目标终端成功接收指示信道的波束信息和公共波束信息,则反馈确认信息,如果目标终端未成功接收指示信道的波束信息和公共波束信息中的任意一个,则反馈非确认信息。网络侧设备在接收到目标终端发送的该反馈信息之后,如果该反馈信息为确认信息,则使用指示的指示信道的波束信息传输指示信道,使用公共波束信息传输多个所述目标对象,如果该反馈信息为非确认信息,则使用目标对象当前使用的波束信息,向目标终端传输目标对象,以及使用指示信道当前使用的波束信息,向目标终端传输指示信道。在预设时间内未接收到反馈信息,则使用目标对象当前使用的波束信息,或所述公共波束信息和目标对象当前使用的波束信息,向目标终端传输目标对象;使用指示信道当前使用的波束信息,或者使用指示的指示信道的波束信息和指示信道当前使用的波束信息,向目标终端传输指示信道。
在一个可能的实现方式中,为了保证传输的可靠性和鲁棒性,在使用所述指示信道指示所述公共波束信息和所述指示信道的波束信息之后,该波束指示方法还可以包括以下至少之一:使用公共波束信息和目标对象当前使用的波束信息,向目标终端传输目标对象;使用指示的指示信道的波束信息和指示信道当前使用的波束信息,向目标终端传输指示信道。
在一个可能的实现方式中,为了使目标终端可以接收到指示信道,在S201之前,该波束指示方法还可以包括:使用预设命令指示该指示信道的波束信息。
其中,预设命令可以是MAC CE命令。
其中,所述预设命令指示的波束信息可以是指示信道所在的CORESET的波束信息。
在上述可能的实现方式中,在S201之后,该波束指示方法还可以包括:使用所述预设命令指示的指示信道的波束信息和指示信道当前使用的波束信息,向目标终端传输指示信道。
或者,在另一个可能的实现方式中,网络侧设备也可以根据目标终端的反馈,确定指示信道所使用的波束信息。因此,在一个可能的实现方式中,在使用预设命令指示该指示信道的波束信息之后,该波束指示方法还可以包括:接收目标终端针对预设命令的第三反馈信息,若第三反馈信息为确认信息,则使用预设命令指示的指示信道的波束信息,发送指示信道;若第三反馈信息为非确认信息,则使用指示信道当前的波束信息,发送指示信道。
在上述可能的实现方式中,网络侧可能未接收到第三反馈信息(可能是目标终端未接收到所述预设命令,也可能是目标终端反馈的第三反馈信息在传输过程中丢失),则可选地,该方法还可以包括:若在预定时间内未接收到第三反馈信息,则使用指示信道当前的波束信息,发送指示信道,或者,使用指示的指示信道的波束信息和指示信道当前使用的波束信息,发送指示信道。
由上述实施例可知,通过本申请实施例的波束指示方法,可以在降低各信道和参考信道波束指示的信令开销、较快波束切换过程的同时,增加波束指示的鲁棒性和灵活性。

可以理解的是,在终端的状态发生变化的情况下,终端监听网络侧设备发送的新的组公共PDCCH即第二组公共PDCCH,以获取第一目标指示信息。
在一个可能的实现方式中,监听第一组公共PDCCH,可以包括:若终端的状态发生变化,则根据第一波束信息监听第一组公共PDCCH,获取第一组公共PDCCH上传输的第一目标指示信息,其中,第一波束信息与第二波束信息不同,第二波束信息为在终端的状态发生变化前监听的第一组公共PDCCH的波束信息。

可以理解的是,至少一个终端的第一目标指示信息在第一组公共PDCCH上的预设位置或预设顺序是网络侧设备通过第一指示信息发送至各个终端的,然后各个终端可以通过监听第一组公共PDCCH,获取第一目标指示信息。
在一个可能的实现方式中,该波束指示方法还可以包括:接收第二指示信息,其中,第二指示信息用于更新至少一个终端中的各个终端的第一目标指示信息在第一组公共PDCCH或第二组公共PDCCH上的预设位置或预设顺序。例如,当至少一个终端中的某个终端的状态发生变化,网络侧设备可以指示或更新第一组公共PDCCH或第二组公共PDCCH上各个终端的公共波束信息的位置或承载顺序。

(2)根据预设的资源信息并结合终端的无线网络临时标识(Radio Network Tempory Identity,RNTI),确定第一上行反馈资源、第二上行反馈资源或第三上行反馈资源;

在上述可能的实现方式中,RNTI可以为小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)。
可以理解的是,确定第一上行反馈资源、第二上行反馈资源或第三上行反馈资源可以是根据预设的资源信息,结合用于唯一标识终端的终端id或RNTI(如C-RNTI小区-RNTI),确定各终端自己的上行反馈资源信息;还可以是从网络配置的上行反馈资源中,各终端使用唯一标识终端的终端id或RNTI(如C-RNTI),选择自己的上行反馈资源信息;还可以是根据预设的资源信息,各终端对应的预设码信息确定自己的上行反馈资源信息,即各终端通过码分的方式使用预设的资源信息;还可以是根据预设的资源信息,各终端对应的预设时域参数(如时域偏移、周期等)确定自己的上行反馈资源信息,即各终端通过时分的方式使用预设的资源信息;还可以是根据预设的资源信息,各终端对应的预设频域参数(如频域偏移、跳频参数等)确定自己的上行反馈资源信息,即各终端通过频分的方式使用预设的资源信息。

可选地,第一上行反馈资源、第二上行反馈资源或第三上行反馈资源也可以是周期资源或非周期资源。
在上述各个可能的实现方式中,由于指示信道指示切换目标对象和/或指示信道的波束信息,或预设命令指示所述指示信道的波束信息,而指示信道或目标对象可能在预定CORESET上传输,从而可能导致预定CORESET的波束信息发生切换,进而使得终端需要更新该预定CORESET的监听时机。因此,在一个可能的实现方式中,该方法还可以包括:若根据所述指示信道的指示或预设命令的指示确定预定CORESET的波束发生切换,则按照以下任一项确定所述预定CORESET的监听时机:
(1)根据切换后的所述预定CORESET的波束信息或根据所述预定CORESET对应的同步信号块SSB确定;

在上述可能的实现方式中,对CORESET#0的波束指示信息,可根据终端反馈的确认信息/非确认信息确定CORESET#0的传输行为,具体参见上述各个可能的实现方式中的具体描述。
