本申请实施例提供的信息激活方法优选用于多TRP单下行控制信息(Downlink Control Information,DCI)场景下,例如,网络侧设备通过MAC CE命令激活的TCI码点中,存在至少一个TCI码点对应着多个联合TCI状态或者多对独立TCI状态,此时可认为每个联合TCI状态或者每对独立TCI状态对应着一个TRP。通常在单DCI场景中网络侧设备通过无线资源控制(Radio Resource Control,RRC)信令配置的控制资源集(Control resource set,CORESET)池标识(CORESETPoolIndex)为一个值,如0或1,或者不配置CORESETPoolIndex。

上述中,根据第一标识信息可确定激活的TCI状态对应的TRP,根据第一标识信息可以确定一个或多个TRP,由于本申请应用场景为未设置TRP身份标识(Identity Document,ID)(RRC参数CORESETPoolIndex)或配置了一个TRP ID值的场景,本申请实施例中可采用第一标识信息来表征一个或多个TRP。
在本申请一种实施例中,在所述网络侧设备配置了联合TCI模式的情况下,根据所述第一MAC CE命令激活的每个TCI状态与码点满足:一个码点对应至少一个联合TCI状态,可选地,每个联合TCI状态为一个所述第一标识信息对应的TCI状态。

若第一MAC CE命令中,所有码点对应的联合TCI状态有多个,或者对应的独立TCI状态有多对,即第一MAC CE命令激活多个联合TCI状态,或者多对独立TCI状态,网络侧设备需要通过目标DCI对目标TCI状态进行指示,此种情况下,目标DCI即为用于确定目标TCI状态的信息,第一信息为目标DCI。所述响应信息为终端基于目标DCI发送的确认信息。
在本申请一种实施例中,所述目标TCI状态为所述网络侧设备通过第一MAC CE命令激活的TCI状态,或者通过DCI指示的TCI状态;第一TCI状态为所述网络侧设备在确定目标TCI状态之前最近一次通过MAC CE激活的TCI状态或通过DCI指示的TCI状态;
相应地,所述网络侧设备确定所述激活的TCI状态中的目标TCI状态的波束生效时间BAT,包括:所述网络侧设备根据目标TCI状态与所述第一TCI状态,确定所述目标TCI状态的BAT。
上述中,目标TCI状态包括两种情况,一种情况下,若第一MAC CE命令只激活一个联合TCI状态,或者一对独立TCI状态,该联合TCI状态或者一对独立TCI状态即为目标TCI状态,网络侧设备不需要通过目标DCI对目标TCI状态进行指示;另一种情况下,若第一MAC CE命令激活多个联合TCI状态,或者多对独立TCI状态,网络侧设备需要通过目标DCI对目标TCI状态进行指示。
相应地,第一TCI状态也包括两种情况,一种情况下,若最近一次通过MAC CE命令只激活一个联合TCI状态,或者一对独立TCI状态,该一个联合TCI状态或者一对独立TCI状态即为第一TCI状态;另一种情况下,若最近一次通过MAC CE命令激活多个联合TCI状态,或者多对独立TCI状态,网络侧设备需要通过DCI对第一TCI状态进行指示。网络侧设备根据前后两次的TCI状态,确定目标TCI状态的BAT。
一种实现方式中,所述第一TCI状态对应第一码点,所述目标TCI状态对应第二码点;
在所述第一TCI状态与所述目标TCI状态满足如下至少一项的情况下, 所述网络侧设备确定所述目标TCI状态的BAT:

终端执行的信息激活方法与网络侧设备执行的信息激活方法具有的相同的技术特征,具体可参见网络侧设备侧的实施例中的描述,在此不做赘述。
以下对本申请提供的信息激活方法进行举例说明。
网络侧设备配置了联合TCI模式(joint TCI模式)和/或独立TCI模式(separate TCI模式)的情况下:
(1)网络侧设备使用MAC CE命令激活TCI状态(TCI state):
(11)在配置联合TCI模式的情况下,每个码点(codepoint)对应1个或多个TCI state,其中每个TCI state是一个TRP的联合TCI状态(joint TCI state)。
例如,codepoint对应{joint TCI state 1和/或joint TCI state 2,……};
(12)在配置独立TCI模式的情况下,每个codepoint对应1对或多对TCI state,其中每对TCI state是一个TRP的separate TCI state。
例如,codepoint对应{DL TCI state 1,UL TCI state 1,和/或DL TCI state 2,UL TCI state 2,……};
(13)在配置联合TCI模式和独立TCI模式的情况下,每个codepoint对应1个或多个joint TCI state、和1对或多对separate TCI state;
(14)可选的,若在MAC CE激活命令中,所有codepoint都只对应一个joint TCI state,或一对separate TCI state,可以据此确定为单TRP场景。
(15)可选的,在MAC CE激活命令中,网络可以总是激活N个joint TCI state、或N对separate TCI state、或N1个separate DL TCI state+N2个separate UL TCI state。
其中,N可以为TRP的数量,或者,N可以为每个codepoint对应的最大TCI state数量。
N1为每个codepoint对应最大DL TCI state数量,N2为每个codepoint对应最大UL TCI state数量。
(2)网络侧设备指示TCI state,网络侧设备使用第一DCI,从MAC CE激活的TCI state中指示目标TCI state。即,第一DCI中的TCI field指示了一个codepoint,该codepoint对应的TCI state即为目标TCI state。
(21)根据网络侧设备上一次指示的codepoint对应的TCI state与第一DCI指示的codepoint对应的TCI state是否相同,确定第一DCI指示的TCI state的波束应用时间,和/或确定是单TRP场景还是多TRP场景。
(211)总是需要BAT,即在第一DCI指示了TCI state后,从第一DCI的ACK之后的Y个符号后的第一个slot,开始生效第一DCI指示的TCI state。
(212)新旧codepoint对应的TCI state相同时,其中,新codepoint是指第一DCI中指示的TCI codepoint,旧codepoint是指上一次DCI指示的TCI codepoint:
a)新旧codepoint对应的TCI state相同的情况下,新旧codepoint对应的TCI state的顺序或位置可以不同,例如旧codepoint对应{TCI state1,TCI state2},新codepoint对应{TCI state 2,TCI state 1},此时可认为前后两个codepoint对应的TCI state相同,不需要做波束切换,故不需要确定BAT;
或者,当新旧codepoint对应的TCI state的顺序或位置不同时,如两个 TRP的TCI state在前后两次的TCI state指示中是相互交换的,在网络指示旧codepoint时,TRP1为TCI state1,TRP2为TCI state2,在网络指示新codepoint时,TRP1为TCI state2,TRP2为TCI state1,每个TRP都需要做波束切换,此时可认为需要确定BAT,两个TRP在BAT后切换波束;
b)当新旧codepoint对应的TCI state的顺序或位置完全相同时,不需要做波束切换,因此不需要BAT。
(213)新codepoint对应的TCI state是旧codepoint对应的TCI state的子集时,例如旧codepoint对应{TCI state1,TCI state2},新codepoint对应{TCI state1},则:
a)由于TCI state1一直在使用中,不需要波束切换,因此不需要BAT
b)在旧codepoint对应的TCI state中,除新codepoint对应的TCI state之外的其它TCI state,仍旧使用,或,不再使用。如上述例子中的TCI state2可以继续使用或者不再使用
c)可以仍为多TRP场景,如网络指示的新codepoint对应着TCI state1,但是旧codepoint对应的TCI state2仍旧使用,此时使用的还是2个TCI state,为多波束传输的场景,每个TRP使用1个TCI state。
d)可以从多TRP场景切换为单TRP场景,如网络指示的新codepoint对应着TCI state1,但是旧codepoint对应的TCI state2不再使用,此时使用的只有1个TCI state,为单波束传输的场景。
(214)旧codepoint对应的TCI state是新codepoint对应的TCI state的子集时,例如旧codepoint对应{TCI state1},新codepoint对应{TCI state1,TCI state2},则:
a)由于TCI state2是之前未使用的,所以需要BAT,确定新codepoint对应的TCI state2的生效时间,即TCI state2在BAT后生效。
b)若在旧codepoint之前网络侧设备曾在预设时长内指示过新codepoint对应的TCI state,则可以不需要BAT,即在所述预设时长内曾使用过新codepoint对应的TCI state2,虽然旧codepoint不对应TCI state2,也可以认为不需要波束切换,而是TCI state2对应的波束仍在备用和跟踪。
c)从单TRP场景切换为多TRP场景,即从旧codepoint对应的TCI state1 确定的单波束传输场景,切换为新codepoint对应的TCI state1和TCI state2确定的多波束传输场景,每个TRP使用1个TCI state。
(215)上述在举例时是以joint TCI为例。若是separate TCI,则将举例中的一个joint TCI state替换为一对separate TCI state即可。
进一步地,在DCI中引入第一信令域。第一信令域用于指示如下至少之一:
TCI field指示的codepoint对应的TCI state中的一个joint TCI state、或一对separate TCI state;
TCI field指示的codepoint对应的全部TCI state;
TCI field指示的codepoint对应的全部TCI state及其顺序或位置。
第一信令域是否存在或是否忽略,根据如下其中一项确定:
网络侧设备配置;
若MAC CE激活了一个joint TCI state或一对separate TCI state,则网络侧设备配置在DCI中不存在第一信令域;
若MAC CE激活了一个joint TCI state或一对separate TCI state,则UE忽略或不解读第一信令域(即使存在)。
进一步地,第一DCI是UL DCI,用于从MAC CE激活的TCI state中指示TCI state;
重用UL DCI中的SRS resource set indicator field,该fileld的特征同第一信令域的描述;
第一DCI可以是调度上行传输的UL DCI,或者是无上行调度的UL DCI。
可选的,根据网络侧设备指示的TCI state中,关联或包含PC参数(PLRS、setting{P0,alpha,closeloopindex}至少之一)的TCI state的数量,确定TRP模式:
(1)如果网络侧设备指示了多个joint TCI state或separate UL TCI state,且这些TCI state都关联或包含PC参数,则:
可通过UL DCI中的第一信令域动态指示UL传输对应的TRP数量(single TRP,or multi-TRP);
或者,认为此时为多TRP场景,UE使用该多个TCI state传输上行信道 (网络侧设备可以调度多TRP的PUSCH或PUCCH);
(2)如果网络侧设备指示了多个joint TCI state或separate UL TCI state,且仅有1个TCI state关联或包含PC参数,则认为此时为单TRP场景,UE使用该TCI state传输上行信道(网络侧设备只能调度单TRP的PUSCH或PUCCH)。
本申请的信息激活方法可实现在多TRP场景中应用统一TCI框架(unified TCI framework)的方案,网络通过激活和指示unified TCI state,可以在single DCI和multi-DCI场景中实现多TRP的公共波束,并且通过波束指示方案还可以支持单TRP和多TRP场景的切换和TRP的选择,可以完备且灵活地支持多TRP场景的unified TCI方案。
