如图2所示,本申请实施例提供一种信息激活方法,包括如下步骤:
步骤101、网络侧设备发送MAC CE命令,所述MAC CE命令包括至少两个第一MAC CE命令,或者第二MAC CE命令;
其中,所述第一MAC CE命令用于激活一个第一标识信息对应的TCI状态(即TCI state),所述第二MAC CE命令用于激活至少两个第二标识信息对应的TCI状态;激活的TCI状态用于确定多个信道的公共波束信息。
MAC CE命令包括两种情况,一种情况下,MAC CE命令包括至少两个第一MAC CE命令,每个第一MAC CE命令用于激活一个第一标识信息对应的TCI状态,这可以理解为第一MAC CE命令与第一标识信息之间为一一对应,例如,网络侧设备可使用对应各发送接收点标识信息(Transmitting Receiving Point Identifier,TRP ID)(如无线资源控制(Radio Resource Control,RRC)参数控制资源集池标识(Control resource set pool index,CORESETPoolIndex)的第一MAC CE命令,来激活各TRP ID对应的TCI状态,进一步地,网络侧设备再使用与第一MAC CE命令对应相同TRP ID的物理下行控制信道(Physical Downlink Control Channel,PDCCH)上的DCI,对从该第一MAC CE命令激活的TCI状态中,指示TRP ID对应的目标TCI状态;另一种情况下,MAC CE命令包括第二MAC CE命令,第二MAC CE命令用于激活至少两个第二TRP ID对应的TCI状态,这可以理解为第二MAC CE命令与第二TRP ID之间为一对多对应。
在本申请中,至少两个第一MAC CE命令可理解为:每次发送一个MAC CE命令,不同次发送的MAC CE命令可以具有相同的、携带扩展逻辑通道标识(extended Logical Channel Identifier,eLCID)的MAC分组数据单元(Packet Data Unit,PDU)子指令(subheader),也可以具有不同的携带eLCID 的MAC PDU subheader。
所述激活的TCI状态包括联合TCI状态(joint TCI state)和独立TCI状态(separate TCI state)中的至少一项。
被激活的TCI状态包括目标TCI状态,目标TCI状态为用于多个信道传输的TCI状态,可以理解为多个信道共用的公共波束信息。
本申请实施例中,网络侧设备发送MAC CE命令,所述MAC CE命令包括至少两个第一MAC CE命令,或者第二MAC CE命令;其中,所述第一MAC CE命令用于激活一个第一标识信息对应的TCI状态,所述第二MAC CE命令用于激活至少两个第二标识信息对应的TCI状态;激活的TCI状态用于确定多个信道的公共波束信息。上述中,在多TRP场景下,激活的TCI状态包括各TRP的用于多个信道传输的TCI状态,可实现在多TRP场景中将各TRP上的同一个波束用于多个信道传输。
上述中,所述第一标识信息包括如下至少一项:

需要说明的是,对于多TRP场景可以通过各种参数的配置来间接标识。例如,多TRP的多DCI(即mDCI,multi-DCI),就是配置了RRC参数CORESETPoolIndex的取值0和取值1,间接标识2个TRP且为mDCI场景。
所述第一MAC CE命令包括用于指示第一TRP的标识的域,例如,第一MAC CE命令包括指示CORESETPoolIndex的域。
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(即joint TCI模式)的情况下,也就是对所有TRP(所有第一标识信息)都配置了joint TCI模式,根据所述第一MAC CE命令激活的每个TCI状态对应一个码点,也就是说,第一MAC CE命令激活的TCI状态中,一个TCI状态对应一个码点,第一MAC CE命令激活的TCI状态用于该第一MAC CE命令中指示的第一标识信息对应的TRP,即所述第一MAC CE命令激活的TCI状态用于所述第一MAC CE命令指示的第一标识信息。

在本申请一种实施例中,允许所述网络侧设备为部分TRP(部分第一标识信息)配置joint TCI模式,为另一部分TRP(另一部分第一标识信息)配置separate TCI模式,根据所述第一MAC CE命令激活的每个TCI状态与码 点满足如下其中一项:
一个码点对应一个联合TCI状态;
一个码点对应一个独立DL TCI状态和一个独立UL TCI状态;

在实施例中,网络侧设备未将第一标识信息配置为联合TCI模式或者独立TCI模式,区分码点对应的TCI状态是联合还是独立的方式可以为:根据TCI状态来自不同的TCI状态池区分是联合TCI状态、独立DL TCI状态或独立UL TCI状态,例如,所述联合TCI状态、所述独立DL TCI状态和所述独立UL TCI状态中的至少两项来自不同的TCI状态池。
区分码点对应的TCI状态是联合还是独立的方式还可以通过在第一MAC CE命令中增加指示信息来指示,例如,所述第一MAC CE命令包括第一指示信息,所述第一指示信息用于指示码点对应的TCI状态为如下其中一项:

(2)每个码点对应一个第二标识信息所对应的TCI状态。例如, codepoint1对应的TCI state用作TRP1对应的联合TCI state,codepoint2对应的TCI state用作TRP2对应的联合TCI state。其中,所述第二标识信息所对应的TCI状态包括一个联合TCI状态。
在本申请一种实施例中,网络侧设备使用第二MAC CE命令激活所有第二标识信息对应的TCI状态,网络侧设备使用RRC信令将所有第二标识信息统一配置为独立TCI模式。即在所述网络侧设备将所述至少两个第二标识信息配置为独立TCI模式的情况下,根据所述第二MAC CE命令激活的TCI状态与码点满足如下其中一项:
(1)一个码点对应所述至少两个第二标识信息中多个第二标识信息所对应的TCI状态,其中,第二标识信息所对应的TCI状态包括一个DL TCI状态和一个UL TCI状态中的至少一项。
例如,codepoint1对应TCI state1、TCI state2、TCI state3、TCI state4,其中,TCI state1和TCI state2用作TRP1对应的独立DL TCI state和独立UL TCI state,TCI state3和TCI state4用作TRP2对应的独立DL TCI state和独立UL TCI state。
(2)每个码点对应一个第二标识信息所对应的TCI状态,其中,第二标识信息对应的TCI状态包括一个DL TCI状态和一个UL TCI状态中的至少一项。

在本申请一种实施例中,网络侧设备使用第二MAC CE命令激活所有第二标识信息对应的TCI状态,网络侧设备使用RRC信令将部分第二标识信息配置为独立TCI模式,另一部分第二标识信息配置为联合TCI模式。即,第一目标标识信息包括所述至少两个第二标识信息中的部分第二标识信息,第二目标标识信息为所述至少两个第二标识信息中除所述第一目标标识信息之外的其他第二标识信息;
在所述网络侧设备将所述第一目标标识信息配置为联合TCI模式,且将所述第二目标标识信息配置为独立TCI模式的情况下,根据所述第二MAC  CE命令激活的TCI状态与码点满足如下其中一项:
(1)一个码点对应所述第一目标标识信息所对应的联合TCI状态,以及所述第二目标标识信息中的第二标识信息的独立TCI状态。
(2)第一码点对应所述第一目标标识信息所对应的联合TCI状态,第二码点对应所述第二目标标识信息所对应的独立TCI状态,所述第一码点为所述第二MAC CE命令激活的码点中的部分码点,所述第二码点为所述第二MAC CE命令激活的码点中除所述第一码点之外的码点。
在本申请一种实施例中,网络侧设备未将第二标识信息配置为联合TCI模式或者独立TCI模式,此种情况下,根据所述第二MAC CE命令激活的每个TCI状态与码点满足如下其中一项:
(1)一个码点对应的TCI状态包括所述至少两个第二标识信息中各第二标识信息对应的TCI状态,其中,第二标识信息对应的TCI状态包括如下其中一项:
联合TCI状态;
独立DL TCI状态和独立UL TCI状态;
独立DL TCI状态;
独立UL TCI状态。
(2)第三码点对应一个第二标识信息所对应的TCI状态,第四码点对应另一个第二标识信息所对应的TCI状态,所述第三码点和第四码点为所述第二MAC CE命令激活的码点中的不同码点,所述一个第二标识信息对应的TCI状态包括联合TCI状态,所述另一个第二标识信息对应的TCI状态包括一个独立DL TCI状态和一个独立UL TCI状态中的至少一项。
本实施例中,由于网络侧设备并不将第二标识信息配置为联合TCI模式或者独立TCI模式,则区分码点对应的TCI状态是联合还是独立的方式可以为:根据TCI状态来自不同的TCI状态池区分是联合TCI状态、独立DL TCI状态或独立UL TCI状态,例如,所述联合TCI状态、所述独立DL TCI状态和所述独立UL TCI状态中的至少两项来自不同的TCI状态池。或者,通过在第二MAC CE命令中增加指示信息来指示,例如,所述第二MAC CE命令包括第二指示信息,所述第二指示信息用于指示码点对应的TCI状态为如下 其中一项:

所述独立DL TCI状态和所述独立UL TCI状态;
所述独立DL TCI状态;

在本申请一种实施例中,根据所述第二MAC CE命令激活的TCI状态与所述至少两个第二标识信息之间的对应关系根据如下其中一项确定:
(1)所述第二MAC CE命令包括的第三指示信息,所述第三指示信息用于指示码点与第二标识信息之间的对应关系,或用于指示所述第二MAC CE命令激活的TCI状态与第二标识信息之间的对应关系;
(2)一个码点对应的多个TCI状态中各TCI状态的位置或顺序与各第二标识信息的标识之间的关联关系;这里所说的各TCI状态的位置或顺序指当一个码点对应多个TCI状态时,该多个TCI状态会按照一定顺序排列,这些TCI状态的排列顺序或者排列位置与各第二标识信息之间具有关联关系。
(3)码点的位置或顺序与各第二标识信息的标识之间的关联关系;这里所说的码点的位置或顺序是网络使用MAC CE激活多个TCI码点时,这些码点会按照一定顺序排列,这些码点的排列顺序或者排列位置与各第二标识信息之间具有关联关系。
需要说明的是,在网络侧设备将第二标识信息配置为独立TCI模式的情况下,激活的TCI状态可以有缺省的情况,例如,只激活独立DL TCI状态,或者只激活独立UL TCI状态。若只激活独立DL TCI状态,则独立UL TCI状态可缺省,缺省的独立UL TCI状态与上一次激活的独立UL TCI状态相同;若只激活独立UL TCI状态,则独立DL TCI状态可缺省,缺省的独立DL TCI状态与上一次激活的独立DL TCI状态相同。
在本申请一种实施例中,所述方法还包括:所述网络侧设备发送第一配置信息,所述第一配置信息用于将所述至少两个第一MAC CE对应的第一标识信息中的至少一个第一标识信息配置为联合TCI模式或独立TCI模式,或者,所述第一配置信息用于将所述第二MAC CE对应的第二标识信息中的至少一个第二标识信息配置为联合TCI模式或独立TCI模式。
也就是说,网络侧设备可以将所有第一标识信息或所有第二标识信息一次性统一配置为联合TCI模式或独立TCI模式,统一配置的情况下,各个标识信息都为联合TCI模式或者都为独立TCI模式,所有第一标识信息或所有第二标识信息共用一个第一配置信息,或者,网络侧设备可以将各第一标识信息或各第二标识信息分别单独进行配置,配置为联合TCI模式或独立TCI模式,单独配置的情况下,各个标识信息的TCI模式可以相同,也可以不同,每个第一标识信息或第二标识信息配置有一个第一配置信息。

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,可参见网络侧设备侧的实施例,在此不做赘述。
以下以第一标识信息或第二标识信息包括TRP ID(如CORESETPoolIndex)为例,对本申请提供的信息激活方法进行举例说明。
激活方式1:网络侧设备使用对应各TRP ID的MAC CE,来激活各TRP ID对应的TCI state,也就是说,MAC CE与TRP之间具有一一对应关系。
网络侧设备再使用与MAC CE对应相同TRP ID的PDCCH上的DCI,DCI的TCI字段(TCI field)从该MAC CE激活的TCI state中,指示该TRP ID对应的TCI state。
(1)网络侧设备使用一个MAC CE激活第一TRP ID(如CORESETPoolIndex值为0)对应的TCI state,网络侧设备使用另一个MAC CE激活第二TRP ID(如CORESETPoolIndex值为1)对应的TCI state。
(2)MAC CE命令包括表征TRP ID的域,如指示CORESETPoolIndex的域。
(3)当网络侧设备使用RRC信令(为各CORESETPoolIndex)配置联合TCI模式(joint TCI)或独立TCI模式(separate TCI)的情况下:
(31)对于joint TCI模式,MAC CE激活的TCI state中,1个TCI state对应1个codepoint。激活的TCI state用于MAC CE中指示的TRP ID。
(32)对于separate TCI模式,MAC CE激活的TCI state中,1个codepoint可以对应1个DL TCI state和1个UL TCI state、或1个DL TCI state、或1个UL TCI state。激活的TCI state用于该MAC CE中指示的TRP ID。
(4)当网络侧设备不显式(为各CORESETPoolIndex)配置联合TCI模式(joint TCI)或独立TCI模式(separate TCI)的情况下:
MAC CE激活的TCI state中,1个codepoint可以对应1个joint TCI state、或1个separate DL TCI state和1个separate UL TCI state、或1个separate DL TCI state、或1个separate UL TCI state。
其中,区分codepoint对应的TCI state是joint还是separate的方式为:根据TCI state来自不同的TCI state pool区分是joint、separate DL、separate UL,和/或,在MAC CE中增加指示信息,指示codepoint对应的TCI state是joint TCI还是separate TCI。
激活方式2:网络侧设备使用对应所有TRP ID(如CORESETPoolIndex)的MAC CE,来激活所有TRP ID对应的TCI state,MAC CE与TRP之间具有一对多的对应关系。
(1)在网络侧设备使用RRC信令配置joint TCI或separate TCI的情况下:
(11)所有TRP(所有CORESETPoolIndex)统一配置为joint TCI,MAC CE激活的TCI state中,1个codepoint对应的TCI state分别对应各TRP,或者各codepoint对应不同TRP。
a)例如:codepoint1对应的TCI state1用作TRP1对应的joint TCI state,codepoint1对应的TCI state2用作TRP2对应的joint TCI state;
b)例如:codepoint1对应的TCI state用作TRP1对应的joint TCI state,codepoint2对应的TCI state用作TRP2对应的joint TCI state。
(12)所有TRP(所有CORESETPoolIndex)统一配置为separate TCI, MAC CE激活的TCI state中,1个codepoint对应的TCI state可以包括多个TRP中各TRP的1个DL TCI state和1个UL TCI state或1个DL TCI state或1个UL TCI state,或者各codepoint对应不同TRP。
a)例如:codepoint1对应的TCI state1和TCI state2用作TRP1对应的separate DL TCI state和separate UL TCI state,codepoint1对应的TCI state3和TCI state4用作TRP2对应的separate DL TCI state和separate UL TCI state;
b)例如:codepoint1对应的2个TCI state用作TRP1对应的separate DL TCI state和separate UL TCI state,codepoint2对应的2个TCI state用作TRP2对应的separate DL TCI state和separate UL TCI state。
(13)部分TRP(部分CORESETPoolIndex)配置为joint TCI,另一部分TRP(另一部分CORESETPoolIndex)配置为separate TCI,MAC CE激活的TCI state中,1个codepoint可以对应一部分TRP的joint TCI state和另一部分TRP的separate TCI state。或者,有的codepoint对应一部分TRP的joint TCI state,有的codepoint对应另一部分TRP的separate TCI state。
(2)在网络侧设备未显式配置joint TCI或separate TCI的情况下:
MAC CE激活的TCI state中,1个codepoint对应的TCI state可以包含:所有TRP(所有CORESETPoolIndex)中各TRP(各CORESETPoolIndex)的TCI state(可以是joint或separate,但不强制同时为joint或separate)。或者,有的codepoint对应一个TRP的joint TCI state,有的codepoint对应一个TRP的separate TCI state。其中,区分codepoint对应的TCI state是joint还是separate的方式同上。
在上述,TCI state或codepoint与TRP(CORESETPoolIndex)的对应关系,可以根据MAC CE中的指示信息确定,或者根据1个codepoint对应的TCI state中各TCI state的位置或顺序与TRP ID(CORESETPoolIndex)建立关联,或者根据codepoint的位置或顺序与TRP ID(CORESETPoolIndex)建立关联。
上述激活的各个TCI state,可以有的TCI state缺省,此时表示缺省的TCI state与上一次激活的TCI state相同。
在上述网络侧设备使用RRC信令配置各TRP的joint TCI或separate TCI 时:
i.网络侧设备对所有TRP统一配置为joint TCI或separate TCI,即所有TRP共用一个配置信息;
ii.或者,网络侧设备为各TRP独立配置为joint TCI或separate TCI,即每个TRP均有一个配置信息。例如,将TRP ID信息(CORESETPoolIndex)和joint TCI与separate TCI的配置信息(joint TCI和separate TCI的模式)建立关联,或者一个信息包含另一个信息。
网络侧设备使用DCI从MAC CE激活的TCI state中指示TCI state。对于多个TRP场景,DCI满足:
1.对于激活方式1,在TRP ID1对应的CORESET上传输的DCI,DCI中的TCI field用于指示TRP ID1对应的MAC CE激活的TCI state。在TRP ID2对应的CORESET上传输的DCI,DCI中的TCI field用于指示TRP ID2对应的MAC CE激活的TCI state。
2.对于激活方式2,DCI可以由特定TRP ID或任意TRP ID对应的CORESET上的PDCCH传输。用于指示任意TRP ID或所有TRP ID对应的MAC CE激活的TCI state。
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:
i.TCI field指示的codepoint对应的TCI state中的一个joint TCI state、或一对separate TCI state;
ii.TCI field指示的codepoint对应的全部TCI state;
iii.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资源集指示字段(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,close loop index}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:
i.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(单TRP(single TRP),or多TRP(multi-TRP)),如第一信令域指示了某一个TCI state,则为单TRP场景,如第一信令域指示了多TCI state,则为多TRP场景
ii.或,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。
