Only when the terminal feeds back ACK information and the base station successfully receives the terminal's ACK information will the RS/PDCCH transmission be updated according to the preconfigured information associated with the signaling. Correspondingly, the terminal will trigger the preconfigured information group of the signaling indication to take effect only after feedback ACK, that is, do not monitor off/monitor on the PDCCH on the TRP exclusive CORESET, and update the measurement associated RS and/or broadcast signal resources. If it is predefined that no ACK/NACK feedback is required, the terminal will update its behavior immediately after successfully receiving the signaling. Correspondingly, the base station will also update the RS/PDCCH transmission after sending the signaling.
- the PDCCH signaling proposed by the embodiment of the present disclosure to dynamically indicate TRP on or off can ensure reliability when only one or part of the TRP services are served during Multi-TRP transmission.
- the remaining TRPs are turned off to save energy consumption of network equipment, and signaling is issued to instruct the UE to trigger terminal energy-saving behavior: do not detect (or use a long listening period) to detect PDCCH and reference signals on part of the Search Space (for example, , SSB, CSI-RS, etc.) measurement behavior update can save energy consumption overhead on both the network side and the terminal side.
- the UE will always monitor the PDCCH corresponding to the TRP on these configured CORESET. If the network device closes some TRP and sends signaling to instruct the UE not to detect Turning off the Search Space corresponding to TRP can save the power consumption of unnecessary blind detection by the terminal.
- DCP will wake up the UE to listen on all Search Spaces on the current BWP. If the UE supports Multi-TRP transmission, then the UE will listen on all Search Spaces corresponding to TRP. However, except for a few scenarios, the UE can ensure reliable transmission by selecting an optimal TRP/link. At this time, there will also be additional energy consumption of the TRP on the base station side and the power consumption overhead of the UE side detecting the PDCCH at the CORESET position corresponding to these TRPs.
- a closed TRP may not send (or send a reference signal (for example, SSB, CSI-RS) with a long listening period); among them, the terminal cannot distinguish the CSI-RS resource configuration of Multi-TRP.
- a reference signal for example, SSB, CSI-RS
- the first signaling used in this disclosure carries the reference signal configuration information associated with the closed TRP to enable the UE to update the CSI-RS measurement behavior on the closed TRP. , further reducing the power consumption of UE measuring CSI-RS.

本公开涉及通信技术领域,特别涉及一种信息指示、处理方法、装置、网络设备及终端设备。
多传输接收点(Multi-Transmission and Receiving Point,Multi-TRP)传输中一个用户设备(User Equipment,UE)同时被多个TRP同时服务,虽然可以保证高可靠性的传输但会导致基站侧极大的能耗开销。在未来第六代移动通信(The 4th Generation mobile communication technology,6G)研究中,随着业务量增大,可靠性要求增高,TRP的个数也会趋于更多,基站侧的能耗开销也会更大。
在***内负载低或信道条件良好的情况下,UE选择一个/组传输质量最好的TRP/链路(link)就可保证高可靠传输,此时,其他的TRP进入休眠状态且指示UE不监听关闭TRP专属的控制资源集(Control resource set,CORESET)上的物理下行控制信道(Physical downlink control channel,PDCCH),但相关技术中并不支持动态TRP开启或关闭的指示,终端无法根据TRP的开关更新相关行为。

目前标准支持在一个带宽部分(Bandwidth Part,BWP)上两个TRP同时给一个UE服务,版本16(R16)的Multi-TRP传输场景分为多下行控制信息(Multiple-Downlink Control Information,M-DCI)框架下的物理下行共享信道(Physical downlink shared channel,PDSCH)和单下行控制信息(Single-Downlink Control Information,S-DCI)框架下的PDSCH传输和以及基于Multi-TRP/panel的超可靠和低时延通信(Ultra-Reliable and Low Latency Communications,URLLC)增强。
1)M-DCI:每个PDSCH只通过一个TRP进行传输,两个TRP独立调度各自的PDSCH。网络侧利用无线资源控制(Radio resource control,RRC)为支持M-DCI传输的UE配置了两种控制资源集池标识(Coresetpoolindex)(0和1)对应的控制资源集(Control Resource Set,CORESET),Multi-TRP在不同的Coresetpoolindex对应的CORESET上传输各自的控制信息。相应地,UE在两种Coresetpoolindex对应的CORESET上都需要检测盲检DCI信息。
2)S-DCI:通过单个物理下行控制信道(Physical downlink control channel,PDCCH)调度一个PDSCH,该PDSCH的每个层(layer)只映射到一个TRP/面板(panel)上去,PDSCH的两个不同的数据流从两个TRP同时发送占用相同的时频资源,或选择其中一个TRP发送。
3)URLLC场景增强:Multi-TRP应用在PDSCH重复传输中,两个TRP发送时分/频分复用的两个相同的PDSCH,这两个PDSCH由一个下行DCI调度,其中DCI的传输配置指示(Transmission Configuration Indication)指示域中一个码点(codepoint)对应两个传输配置指示(Transmission Configuration Indicator,TCI)状态(state),这两个TCI state分别对应两个TRP。
本公开实施例提供了信息指示、处理方法、装置、网络设备及终端设备,用以解决相关技术中并不支持动态TRP开启或关闭的指示,终端无法根据TRP的开关更新行为的问题。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
如图2所示,本公开实施例提供一种信息指示方法,由网络设备执行,包括:
步骤S201,向终端发送第一信令;
其中,所述第一信令用于指示至少一个或一组传输接收点(TRP)的开启和/或关闭。
需要说明的是,该第一信令可以同时实现对一个或多个TRP的指示,也可以同时实现对一组或多组TRP的指示。
可选地,该第一信令还用于触发配置信息组切换后的行为;
当终端收到该第一信令之后,便能后知道具体切换到哪一个配置信息组,然后执行切换到的配置信息组相对应的行为。
需要说明的是,本公开实施例中所说的网络设备可以理解为是能够为终端服务的多个TRP中的一个,多个TRP之间能够进行协调,即各个TRP相互通知各自是开启还是关闭,然后由一个TRP进行开启或关闭的动态指示。
可选地,本公开的至少一个实施例中,该第一信令中携带第一指示域,所述第一指示域通过比特位图或码点方式指示至少一个或一组TRP的开启和/或关闭。
例如,假设存在N个TRP,当采用比特位图方式指示时,第一指示域携带N个比特,每个比特对应指示一个TRP的开启或关闭的状态,例如,当某一个比特位的值为0时,指示该比特位对应的TRP为关闭状态,当某一个比特位的值为1时,指示该比特位对应的TRP为开启状态;或者,例如,当某一个比特位的值为1时,指示该比特位对应的TRP为关闭状态,当某一个比特位的值为0时,指示该比特位对应的TRP为开启状态。当采用码点方式指示时,第一指示域携带的比特位的值用于指示具体开启的TRP的索引。
可选地,所述第一信令包括动态信令和/或无线资源控制(RRC)信令。
可选地,所述动态信令包括以下至少一项:
组公共控制物理下行控制信道(PDCCH)、非调度PDCCH、调度PDCCH或媒体接入控制-控制单元(MAC-Control Element,MAC-CE)。
优选地,该RRC信令为组公共RRC信令。
可选地,所述RRC信令通过以下至少一项承载:

可选地,该非调度PDCCH用于传输非调度下行控制信息(DCI);例如,该非调度DCI可以为DCI格式2_0(format 2_0)、DCI格式2_6(format 2_6)等。
当第一信令为MAC CE时,说明该第一信令为MAC层的第一信令。
可选地,所述第一信令的配置粒度包括以下至少一项:

可以理解为该第一信令是终端专属的。
A12、终端组;
可以理解为该第一信令是终端组专属的。
A13、小区;
可以理解为该第一信令是小区专属的。
可选地,所述第一信令通过显式方式或隐式方式进行至少一个或一组TRP的开启和/或关闭的指示;
其中,所述显式方式包括以下至少一项:休眠BWP切换指示、配置信息组指示、TRP状态指示、TRP标识指示;
所述隐式方式包括以下至少一项:准共址(Quasi Co-Location,QCL)信息、PDCCH发送位置、搜索空间集组(Search Space Set Group,SSSG)切换指示信息、PDCCH跳过指示信息。
下面分别对不同的指示方式进行详细说明如下。
一、所述第一信令基于休眠BWP切换指示进行至少一个或一组TRP的开启和/或关闭的指示
在此种情况下,所述方法还包括:
向终端发送与TRP状态具有关联关系的至少一个休眠BWP对应的配置信息组;
其中,每个休眠BWP对应一个TRP或一组TRP,所述每个休眠BWP对应TRP关闭状态下所使用的一个配置信息组;
所述配置信息组包括以下至少一项:

可选地,每一个休眠BWP关联一个目标BWP,所述目标BWP为当前激活BWP或除当前激活BWP之外的其他BWP。
可选地,当目标BWP为当前激活BWP的情况下,当第一信令的指示生效后,终端在当前激活BWP上切换配置信息;当目标BWP为当前激活BWP之外的其他BWP的情况下,当第一信令的指示生效后,终端要从当前激活BWP切换到其他BWP上。
需要注意的是,此应用情况下,终端设备在基于第一指示域进行TRP开启或关闭的确定时,需要基于接收到第一信令时该TRP的开关或关闭状态决定,例如,当第一指示域中指示了TRP1的休眠BWP,若终端设备接收到第一信令时,该TRP1处于开启状态,则终端设备确定该第一指示域的指示TRP1关闭,则终端在TRP1上切换到TRP1对应的休眠BWP对应的配置信息组;若终端设备接收到第一信令时,该TRP1处于关闭状态,则终端设备确定该第一指示域的指示TRP1开启,则终端在TRP1上切换到TRP1开启状态所关联的配置信息组或者是恢复激活BWP上的初始行为。
此种情况下,可以理解为第一指示域为TRP指示域,承载动态指示开启/关闭TRP信息;当采用比特位图方式指示时,TRP指示域中的N个比特对应N个或N组TRP,比特取值为0指示TRP关闭,比特取值为1指示TRP开启。当采用码点方式指示时,TRP指示域中的比特位的取值指示开启(或关闭)TRP索引(index)(也可以为TRP组index或休眠BWP index)。
还需要说明的是,此种情况下,终端设备获取的至少一个休眠BWP与TRP状态的关联关系可以预配置、预定义或网络设备配置的。
二、所述第一信令基于配置信息组指示进行至少一个或一组TRP的开启和/或关闭的指示

其中,每个配置信息组对应一个TRP或一组TRP,所述每个配置信息组对应TRP关闭状态下所使用的一组配置信息;
其中,每个配置信息组包括以下至少一项:
RS配置信息组、广播信号配置信息组、CORESET配置信息。
需要注意的是,此应用情况下,终端设备在基于第一指示域进行TRP开启或关闭的确定时,需要基于接收到第一信令时该TRP的开关或关闭状态决定,例如,当第一指示域中指示了TRP1的配置信息组,若终端设备接收到第一信令时,该TRP1处于开启状态,则终端设备确定该第一指示域的指示TRP1关闭,则终端在TRP1上切换到TRP1对应的配置信息组;若终端设备接收到第一信令时,该TRP1处于关闭状态,则终端设备确定该第一指示域的指示TRP1开启,则终端在TRP1上切换到TRP1开启状态所关联的配置信息组或者是恢复激活BWP上的初始行为。
此种情况下,可以理解为第一指示域为配置信息组指示域,承载动态指示开启/关闭TRP信息;当采用比特位图方式指示时,配置信息组指示域中的N个比特对应N个配置信息组,比特取值为0指示配置信息组去激活,比特取值为1指示配置信息组激活。当采用码点方式指示时,TRP指示域中的比特位的取值指示切换的配置信息组。
还需要说明的是,此种情况下,终端设备获取的至少一个配置信息组与TRP状态的关联关系可以预配置、预定义或网络设备配置的。
三、所述第一信令基于TRP状态指示进行至少一个或一组TRP的开启和/或关闭的指示
此种情况下,所述方法,还包括:
向终端发送与TRP的状态具有关联关系的至少一套配置信息;
其中,每套配置信息对应一个TRP或一组TRP,一套配置信息包括第一个配置信息组和第二个配置信息组,所述第一个配置信息组对应TRP关闭状态下所使用的配置信息,所述第二个配置信息组对应TRP打开状态下所使用的配置信息;
其中,所述配置信息组包括以下至少一项:
RS配置信息组、广播信号配置信息组、CORESET配置信息。
此种情况下,可以理解为第一指示域为TRP指示域,承载动态指示开启/关闭TRP信息;当采用比特位图方式指示时,TRP指示域中的N个比特对
应N个或N组TRP的开启(或关闭)的指示,比特取值为0指示TRP关闭,比特取值为1指示TRP开启。当采用码点方式指示时,TRP指示域中的比特位的取值指示开启(或关闭)TRP index(也可以为TRP组index)。
当终端确定开启某一个TRP时,切换到该TRP对应的第二个配置信息组;当终端确定关闭某一个TRP时,切换到该TRP对应的第一个配置信息组。
还需要说明的是,此种情况下,终端设备获取的至少一套配置信息与TRP状态的关联关系可以预配置、预定义或网络设备配置的。
四、所述第一信令基于TRP标识指示进行至少一个或一组TRP的开启和/或关闭的指示
可选地,该TRP标识可以理解为TRP索引(index),或者TRP编号,例如,第一信令中携带的第一指示域中指示了TRP1和TRP2的索引,则第一信令用于指示关闭TRP1和TRP2。
需要说明的是,此种情况下,主要是采用TRP标识指示需要关闭的TRP,即若第一信令中携带了哪几个或哪几组TRP的标识,则终端便确定关闭这几个或几组TRP,进一步地,可以预配置、预定义或网络设备配置TRP关闭状态下所对应的配置信息组,当终端确定关闭某一个TRP时,则切换到该TRP对应的配置信息组。
该配置信息组包括以下至少一项:
RS配置信息组、广播信号配置信息组、CORESET配置信息。
五、在所述第一信令基于第一信息进行至少一个或一组TRP的开启和/或关闭的指示
具体地,该第一信息为QCL信息或PDCCH发送位置;可选地,该QCL信息包括传输配置指示(TCI)状态信息。
在此种情况下,所述方法,还包括:

的配置信息;
其中,所述配置信息组包括以下至少一项:
RS配置信息组、广播信号配置信息组和CORESET配置信息。
例如,当第一信息为QCL信息的情况下,可以理解为是复用现有指示域进行TRP开启(或关闭)的指示;此种情况下,可以理解为第一指示域为QCL相关指示域(例如为TCI指示域),QCL相关指示域中指示的内容与TRP存在关联关系,例如,当QCL相关指示域中指示的TCI状态为0时对应TRP1,当QCL相关指示域中指示的TCI状态为1时对应TRP 2。
例如,当第一信息为PDCCH发送位置的情况下,可以理解为若TRP没有专属的区分信息,则为每一个TRP或每一组TRP关联一个PDCCH发送位置(例如,该发送位置可以为CORESET或搜索空间(Search Space,SS)),网络设备在开启(或关闭)TRP的专属的发送位置上发送特定TRP对应的PDCCH。
需要注意的是,以第一信息为QCL信息为例,此应用情况下,终端设备在基于第一指示域进行TRP开启或关闭的确定时,需要基于接收到第一信令时该TRP的开关或关闭状态决定,例如,当第一指示域中指示了TRP1对应的TCI状态,若终端设备接收到第一信令时,该TRP1处于开启状态,则终端设备确定该第一指示域的指示TRP1关闭,则终端在TRP1上切换到TRP1对应的配置信息组;若终端设备接收到第一信令时,该TRP1处于关闭状态,则终端设备确定该第一指示域的指示TRP1开启,则终端在TRP1上切换到TRP1开启状态所关联的配置信息组。
还需要说明的是,此种情况下,终端设备获取的至少一个QCL信息或至少一个PDCCH发送位置与TRP状态的关联关系可以预配置、预定义或网络设备配置的。
六、在所述第一信令基于SSSG切换指示信息进行至少一个或一组TRP的开启和/或关闭的指示
此种情况下,所述方法,还包括:
向终端发送与TRP状态具有关联关系的至少一个CORESET上的SSSG切换指示信息对应的SSSG;
其中,每一个CORESET对应一个TRP或一组TRP,所述SSSG切换指示信息对应配置两个SSSG或所述SSSG切换指示信息对应配置一个SSSG;所述两个SSSG包括第一SSSG和第二SSSG,所述第一SSSG对应TRP关闭状态下所使用的PDCCH监听周期,所述第二SSSG对应TRP开启状态下所使用的PDCCH监听周期;在SSSG切换指示信息对应配置一个SSSG的情况下,指示终端在TRP关闭情况下不进行PDCCH监听。
此种情况下,可以理解为第一指示域为SSSG切换指示域,即复用现有的SSSG切换指示域进行TRP开启(或关闭)的指示;具体地,可以在TRP专属CORESET上配置两个SSSG,分别对应TRP开启(或关闭)状态的PDCCH监听周期;也可以仅在TRP专属CORESET上配置一个SSSG,该SSSG对应TRP开启状态所使用的PDCCH监听周期,而在TRP关闭状态不监听PDCCH,网络设备根据开启(或关闭)TRP在关联的位置上发送此第一信令。
还需要说明的是,此种情况下,终端设备获取的至少一个CORESET上的SSSG切换指示信息对应的SSSG与TRP状态的关联关系可以预配置、预定义或网络设备配置的。
七、所述第一信令基于PDCCH跳过(Skipping)指示信息进行至少一个或一组TRP的开启和/或关闭的指示
此种情况下,所述方法,还包括:
向终端发送与TRP状态具有关联关系的至少一个PDCCH跳过步数;
其中,每一PDCCH跳过步数对应一个TRP或一组TRP的开启或关闭状态。
此种情况下,可以理解为第一指示域为PDCCH Skipping指示域,即复用现有的PDCCH Skipping指示域进行TRP开启(或关闭)的指示;具体地,先分别为不同的TRP的开启(或关闭)关联一个PDCCH跳过步数,当终端设备获取到PDCCH Skipping指示域中的PDCCH跳过步数时,便能基于该PDCCH跳过步数与TRP状态的关联关系,确定是开启还是关闭某一个TRP。
需要注意的是,此应用情况下,终端设备在基于第一指示域进行TRP开启或关闭的确定时,需要基于接收到第一信令时该TRP的开关或关闭状态决
定,例如,当第一指示域中指示了TRP1的PDCCH跳过步数,若终端设备接收到第一信令时,该TRP1处于开启状态,则终端设备确定该第一指示域的指示TRP1关闭,则终端在TRP1上不监听TRP1对应的一个或一组搜索空间上的PDCCH;若终端设备接收到第一信令时,该TRP1处于关闭状态,则终端设备确定该第一指示域的指示TRP1开启,则终端在TRP1上触发测量TRP1对应的TRS资源。
还需要说明的是,此种情况下,终端设备获取的至少一个PDCCH跳过步数与TRP状态的关联关系可以预配置、预定义或网络设备配置的。
需要说明的是,终端设备在接收到第一信令后,只需要解析得到第一信令中承载的特定信息,然后基于特定信息与TRP状态的关联关系,确定是否开启TRP还是关闭TRP,然后执行对应的动作即可。
例如,在终端根据所述第一信令确定第一TRP关闭的情况下,执行第一操作;
其中,所述第一操作包括以下至少一项:
B11、不监听所述第一TRP对应的一个或一组搜索空间上的PDCCH;
B12、以第一周期监听所述第一TRP对应的一个或一组搜索空间上的PDCCH,所述第一周期的周期长度大于所述第一TRP开启情况下所使用的监听周期的长度;
B13、切换到第一TRP关闭状态所关联的配置信息组,所述配置信息组包括以下至少一项:参考信号RS配置信息组、广播信号配置信息组和控制资源集CORESET配置信息。

其中,所述第二操作包括以下至少一项:
B21、恢复激活BWP上的初始行为;
B22、切换到第二TRP开启状态所关联的配置信息组,所述配置信息组包括以下至少一项:RS配置信息组、广播信号配置信息组和CORESET配置信息;
B23、触发测量所述第二TRP对应的TRS资源。
可选地,本公开的至少一个实施例中,在所述向终端发送第一信令之前,所述方法,还包括:
向终端发送第一指示信息,所述第一指示信息用于指示是否支持第一信令重传的功能。
终端设备接收到该第一指示信息后,在后续接收第一信令的过程中,若支持第一信令重传的功能,则根据所述第一信令的接收情况,在混合自动重传请求应答(Hybrid automatic repeat request acknowledgement,HARQ-ACK)反馈位置向网络设备发送HARQ-ACK信息,所述HARQ-ACK信息包括:确认信息或非确认信息。在支持第一信令重传的功能的情况下,若网络设备在HARQ-ACK反馈位置未收到确认信息,则重新向所述终端发送所述第一信令。
例如,当网络设备不支持信令的重传时,网络设备根据TRP开启(或关闭)状态的转换下发一次第一信令,网络设备默认终端设备可以接收正确,按照TRP状态更新相应开启(或关闭)的行为。当网络设备支持信令的重传,网络设备在信令中携带/预定义反馈肯定确认(Acknowledgement,ACK)/否定确认(Negative Acknowledge,NACK)位置,终端正确接收到后在信令指示位置反馈ACK/NACK信息,网络设备未接收到ACK信息后继续下发该信令,直到终端设备正确接收或第一信令达到最大重传次数。
可选地,本公开的至少一个实施例中,所述方法,还包括:
向所述终端发送针对每个跟踪参考信号(tracking reference signal,TRS)资源或每组TRS资源的资源配置信息,所述资源配置信息用于指示所述终端在目标TRP由关闭到开启时触发所述目标TRP对应的TRS资源生效。
需要说明的是,通过此种配置可以使得在目标TRP开启时,终端设备能够快速的接入该目标TRP。
下面对本公开的具体应用举例说明如下。
应用情况一、基于休眠BWP切换的动态TRP开启(或关闭)指示
具体包括如下过程:
步骤110,网络设备根据可支持的Multi-TRP个数或组数配置N个休眠BWP(第一休眠BWP,第二休眠BWP…第N休眠BWP,N>1),每个休眠BWP对应一个或一组TRP关闭且关闭的TRP专属的CORESET不配置
Search Space和关闭TRP对应的RS信号(例如,信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS),同步信号/物理广播信道信号块(Synchronization Signal and PBCH block,SSB,也可以称为同步信号块),信道探测参考信号(sounding reference signals,SRS))和/或广播信号长周期(或非周期)配置,同时每个休眠关联一个BWP配置:1)关联BWP是当前激活BWP表示信令生效后在当前BWP上切换配置信息;2)关联的BWP是其他BWP则信令生效后切换至关联BWP。
步骤120,当网络设备触发Multi-TRP中一个或一组由TRP开启状态转换到关闭状态(关闭状态转换到开启状态),网络下发组公共(group common)DCI以比特位图(bitmap)/码点(codepoint)方式指示一个(或一组)UE的一个或(一组)TRP的关闭(或开启)的信息;
步骤130,接收到信令的UE按照指示中关闭的TRP关联的休眠BWP配置信息触发行为:不检测休眠BWP关联的CORESET上的PDCCH,休眠BWP关联的RS配置更新RS测量;信令中指示开启的TRP,UE继续监测TRP专属CORESET上PDCCH,按照原始配置的RS配置测量。如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP。
其中,如果同时指示多个(或多组)TRP关闭时,这些关闭TRP对应的休眠BWP同时生效,即UE同时不监听这些关联休眠BWP上关闭TRP专属CORESET上PDCCH,长周期/非周期测量关联的RS资源。
下面分别以2个TRP和4个TRP下动态TRP开关信令内容设计为例,详细介绍此实施例中提出的指示方法。

或广播信号,如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP;
[0,1]指示第二休眠BWP配置信息生效,该BWP的CORESETpoolindex1上不配置SS,TRP2只配置长周期/非周期的RS信号和/或广播信号,如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP;
[0,0]指示原始的激活BWP配置信息生效,原始的BWP的CORESETpoolindex0和1维持原本Search Space配置,维持原始的BWP上RS信号和/或广播信号的配置。
b)TRP指示域采用1比特指示:

[1]指示TRP 2开启/关闭间状态切换:第二休眠BWP配置信息生效,该BWP的CORESETpool index1对应的CORESET上不配置SS,TRP2只配置长周期(或非周期)的RS信号和/或广播信号,如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP;
其中当关闭的TRP再次打开为UE提供服务时,仍然下发此信令(TRP指示域与TRP关闭时比特域设置一致),代表TRP重新打开。
2、在4个TRP为一个UE服务的情况下
a)单个TRP关闭指示:

与上述两种指示内容类似,[1,0]和[1,1]对应TRP3和4on/off间状态切换:UE切换到/离开第三休眠BWP和第四休眠BWP,该休眠BWP上对应关闭TRP专属对应的CORESET上不配置SS,关闭TRP只配置长周期(或非周期)的RS信号和/或广播信号,如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP。
其中,当关闭的TRP再次打开为UE提供服务时,仍然下发此信令(TRP指示域与TRP关闭时比特域设置一致),代表TRP重新打开。
2)TRP指示域采用4比特bitmap指示
四个比特分别对应四个TRP,比特0-TRP OFF,比特1-TRP ON,UE接收此信令后,切换到/离开网络侧配置的对应休眠BWP,该BWP上关闭的TRP专属的CORESET上不配置SS,关闭的TRP只配置长周期(或非周期)的RS信号和/或广播信号。相应的,UE在不配置SS的CORESET上监听PDCCH,长周期/非周期RS信号和/或广播信号。如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP
b)TRP组开启/关闭指示:
以4个TRP分两组,每组两个TRP为例,网络设备为UE配置第一休眠BWP和第二休眠BWP分别对应TRP组1关闭和TRP组2关闭后终端更新的配置信息,如果该休眠BWP关联的BWP是当前激活BWP表示信令生效后在UE在当前BWP上切换配置信息,否则信令生效后UE切换至关联BWP。

[1]指示TRP组2开启/关闭间状态切换:第二休眠BWP配置信息生效,该BWP的TRP组2专属CORESET上不配置SS,TRP组2只配置长周期/非周期的RS信号和/或广播信号。
应用情况二、基于配置信息组切换的动态TRP开/关指示
具体包括如下过程:
步骤21,网络设备根据Multi-TRP个数以及可能的TRP关闭的情况配置N个RS资源组(Resource Groups),每个RS Resource Group里对应一个/组TRP长周期/非周期的RS信号(例如,CSI-RS,SSB,SRS)和/或广播信号和/或一个(或一组)TRP专属CORESET上不配置SS。
步骤22,当网络侧触发一个(或一组)TRP在开启/关闭间状态切换时,下发信令指示UE对应的RS Resource Group标识(ID);
步骤23,UE根据接收到信令指示后,触发监不监听TRP专属CORESET上PDCCH,更新测量关联的RS和/或广播信号资源。
下面以2个TRP下动态关闭TRP信令内容设计分别为例,详细介绍此实施例中提出的指示方法,RRC配置如下信息:
RS Resource Group 0:TRP1和TRP2配置正常RS信号和/或广播信号资源配置,TRP1和TRP2专属对应的CORESET上正常配置SS;
RS Resource Group 1:TRP1配置长周期(或非周期)的RS信号和或广播信号资源配置,TRP2配置正常RS信号和/或广播信号资源配置,TRP1专属对应的CORESET上不配置SS,TRP2专属对应的CORESET上正常配置SS;

应用情况三、基于TRP关联的配置信息组切换的动态TRP开/关指示
具体包括如下过程:
步骤31,网络设备为每个(或每组)TRP关联两个Resource group;
RS Resource group 0:这个(或这组)TRP处于开启状态下的对应的RS信号(例如,CSI-RS,SSB,SRS)和/或广播信号正常测量,TRP专属CORESET正常配置Search Space;
RS Resource group 1:这个(或这组)TRP处于关闭状态下的对应的RS信号(例如,CSI-RS,SSB,SRS)和/或广播信号长周期/非周期测量,TRP专属CORESET不配置Search Space。
步骤32,信令中每个(或每组)TRP对应1比特指示Resource group ID,当网络设备触发某一个(或一组)TRP进行开启/关闭间状态转换时,下发信令指示对应TRP在关联的Resource group 0和Resource group 1间切换,比特设置0:Resource group 0生效;比特设置1:Resource group 1生效;
步骤33,网络设备触发一个/多个TRP在开启/关闭间状态切换时,下发信令指示UE对应的Resource Group ID,UE根据接收到信令指示后,监不监
听TRP专属CORESET上PDCCH,测量生效的RS信号和/或广播信号资源。
应用情况四、基于TCI关联的配置信息组切换的动态TRP开/关指示
具体包括如下过程:
步骤41,网络设备为每个TRP对应的TCI state关联两个Resource group,Resource group 0表示TRP处于ON状态下的对应的RS常规测量,TRP专属CORESET正常配置Search Space。Resource group 1表示TRP处于关闭状态下的对应的RS(例如,CSI-RS,SSB,SRS)长周期(或非周期)测量,TRP专属CORESET不配置Search Space。
步骤42,信令中为每个TRP的TCI指示域关联1比特Resource group指示域:指示Resource group ID;当网络设备触发某一个/组TRP进行开启/关闭间状态转换时,下发信令指示对应TCI state关联的Resource group指示域在Resource group 0和Resource group 1间切换,比特设置0:Resource group 0;比特设置1:Resource group 1;
步骤43,终端检测到此信令,根据TCI指示和Resource group ID,触发关联的行为,例如,信令指示TCI 0,即Resource group 0,UE不在监听TCI0对应TRP专属CORESET上的PDCCH,根据Resource group 0配置测量参考信号。
应用情况五、基于发送位置和配置信息组切换的动态TRP开/关指示
具体包括如下过程:
步骤51,网络侧为每个(或每组)TRP关联的CORESET/Coresetpoolindex上配置两个或多个Resource group(如果网络侧未配置TRP专属CORESET,则根据现有CORESET/Search Space关联一个或一组TRP);
步骤52,Group Common信令中设置Resource group指示域,当网络设备触发一个(或一组)TRP进行开启/关闭间状态转换时,在TRP相关联的CORESET/Search Space上下发该信令,信令中Resource group指示域指示TRP状态对应的RS Resource group ID;
步骤53,终端在TRP关联的CORESET/Search Space上检测到该信号,根据信号中RS Resource group ID测量相关的参考信号,根据接收到信号之前TRP状态判断是否监听这个/组TRP专属的CRORSET上PDCCH。
应用情况六、基于PDCCH监听自适应和配置信息组切换的动态TRP开/关指示
与应用情况五类似,网络设备为每个(或每组)TRP关联的CORESET上关联两个SSSG(SSSG0-常规监听;SSSG1-长监听周期/不监听),每个SSSG关联一个Resource group(SSSG0关联CSI-Resource group 0-常规参考信号(例如,CSI-RS,SSB,SRS)和/或广播信号配置;SSSG1关联Resource group1-长周期/非周期参考信号和/或广播信号配置),当网络设备触发一个(或一组)TRP进行开启/关闭间状态转换时,信令在TRP关联的CORESET上下发DCI format 2_0,通过SearchSpaceSwitchTrigger指示域在SSSG0和SSSG1间切换,隐式指示TRP开启/关闭状态转换,同时触发UE执行Resource group切换。
应用情况七、基于group common RRC信令的TRP开/关指示
步骤71,网络设备根据可支持的Multi-TRP个数或组及可能的TRP(组)开关情况,预先配置N个配置信息组,信息组中包括至少以下一种配置:
RS Resource Group,包含一个/组TRP关联的周期性/非周期的RS信号(例如CSI-RS、SSB、SRS)和/或广播信号的时频资源和/或周期和/或终端上报测量量等配置信息;
一个/组TRP专属CORESET上不配置SS;
TRP标识信息,例如TRP/TRP组ID,CORESETPoolindex;
BWP ID;
载波(Component Carrier,CC)ID。
步骤72,当网络设备触发一个/组TRP在开启/关闭间状态切换时,下发group Common RRC信令承载指示TRP开关信息和/或预配置信息组指示信息指示并触发至少一组预配置信息组生效;其中,
基于codepoint和/或bitmap指示的TRP开启/关闭信息;
例如,bitmap指示:0001—TRP(组)0-2关闭,TRP(组)3开启;
codepoint指示:00-TRP(组)0关闭/开启。
基于codepoint和/或bitmap指示预配置信息组生效的信息;
例如,bitmap指示:0001—预配置信息组0-2(预定义与TRP的关联关
系:对应TRP(组)0-2关闭)失效,预配置信息组3(TRP(组)3开启)生效;
其中,group common RRC信令可通过SIB消息和/或PBCH和/或PDSCH和/或由group common PDCCH调度的group common PDSCH承载;下面以PBCH承载2个TRP开关信息为例:
2.1预定义4组配置资源信息组,Group 0-2个TRP全开RS/CORESET配置信息;
Group 1-TRP1开启TRP2关闭下,RS/CORESET配置信息;Group 2-TRP1关闭TRP2开启下,RS/CORESET配置信息;Group 3-2个TRP全部关闭RS/CORESET配置信息;
2.2在MIB消息中增加TRP开关/配置信息组指示域,定义指示域长度为2比特,基站根据TRP开关状态的改变,在MIB消息中的指示域中指示相应的数值,如:
00-TRP1和2全部开启,预配置信息组Group 0生效;
01-TRP1开启TRP2关闭,预配置信息组Group 1生效;
10-TRP2开启TRP1关闭,预配置信息组Group 2生效;
11-TRP1和2全部关闭,预配置信息组Group 3生效;
2.3终端在MIB消息的接收中检测到TRP开关/配置信息组指示域指示的TRP开关相应的信息和/或配置信息组,更新相应的行为。
步骤73,可选地,此信令可预定义配置是否反馈ACK/NACK。如果预定义配置需要终端反馈ACK/NACK,则UE根据接收到信令指示后,反馈ACK/NACK信息。只有当终端反馈ACK信息且基站成功接收到终端的ACK信息后才会按照信令关联的预配置信息更新RS/PDCCH发送。相应地,终端在反馈ACK后才会触发信令指示的预配置信息组生效,即不监听关闭/监听开启TRP专属CORESET上PDCCH,更新测量关联的RS和/或广播信号资源。如果预定义不需要反馈ACK/NACK,则终端成功接收到信令后就立即更新行为,相应地,基站下发信令后也更新RS/PDCCH发送。
需要说明的是,本公开实施例提出的动态指示TRP开启或关闭的PDCCH信令,在Multi-TRP传输中,当只有一个或部分TRP服务即可保可靠性,吞
吐量传输的情况下,关闭其余的TRP节省网络设备能耗的同时下发信令指示UE触发终端节能行为:不检测(或以长监听周期)检测部分Search Space上的PDCCH和参考信号(例如,SSB,CSI-RS等)测量行为更新,可以同时节省网络侧和终端侧的能耗开销。当需要关闭的TRP开启保证服务时,下发指令恢复原始的Multi-TRP传输下UE的行为,保证高可靠传输。在保证***高可靠和高吞吐传输时,同时降低网络侧和终端的能耗开销。
综上可知,本公开实施例能够达到如下有益效果:
1、相关技术的Multi-TRP传输中,如果高层配置了区分TRP的CORESET,UE会一直在这些配置的CORESET上监听对应TRP的PDCCH,网络设备如果关闭一些TRP并下发信令指示UE不检测关闭TRP对应的Search Space,可以节省终端进行不必要的盲检功耗。
2、DCP机制中,DCP会唤醒UE在当前BWP上所有Search Space监听,如果UE支持Multi-TRP传输,那么UE会在所有TRP对应的Search Space上监听。然而,除了少数场景,UE选择一个最佳TRP/link即可保证可靠传输,这时也会存在基站侧TRP额外的能耗消耗以及UE侧检测这些TRP对应CORESET位置上的PDCCH的功耗开销。
3、关闭的TRP可以不发送(或以长监听周期)发送参考信号(例如,SSB,CSI-RS);其中,终端无法区分Multi-TRP的CSI-RS资源配置,网络设备关闭一部分TRP时,这些TRP可以仅维持长周期(或非周期)的CSI-RS,本公开采用的第一信令中携带关闭TRP关联的参考信号配置信息可以使UE对关闭的TRP上CSI-RS测量行为进行更新,进一步减低UE测量CSI-RS的功耗。
