Description

传输配置指示状态确定方法、装置及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及传输配置指示(transmission configuration indication，TCI)状态确定方法、装置及存储介质。
背景技术
在新无线技术(New Radio，NR)中，例如通信频段在frequency range 2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束(beam)的发送和接收。当网络设备(例如基站)有多个传输接收点(Transmission Reception Point，TRP)时，可以使用多个TRP为终端提供服务，包括使用多个TRP为终端发送物理下行控制信道(physical downlink control channel，PDCCH)。
相关技术中，支持使用多个TRP进行PDCCH的重复传输(Multi-TRP PDCCH repetition)。例如，Multi-TRP PDCCH repetition中，配置两个控制资源集(Control Resource Set，CORESET)，并配置CORESET对应的TCI状态(state)。每个CORESET对应配置一个TCI状态，并分别配置搜索空间集(Search Space set，SS set)与两个CORESET分别关联。即配置了两个具有链接关系的SS set，关联不同的CORESET和对应不同的TCI状态。其中，具有链接关系的两个SS set可以理解为是两个SS set中PDCCH候选资源(candidate)索引(index)一样的两个PDCCH candidate用于发送一个下行控制信息(Downlink Control Information，DCI)。传统方法中，基于单个下行控制信令(single-DCI，S-DCI)指示PDSCH repetition的TCI状态，即该DCI对应的CORESET的控制资源集池索引(CORESETPoolIndex)是一样的。
然而，当用于PDCCH repetition传输的多个具有链接关系的SS set所对应的CORESET的CORESETPoolIndex不一样时，该具有链接关系的多个SS set中的PDCCH candidate携带的DCI中的TCI域(field)的码点(codepoint)对应的TCI state如何配置，是需要解决的问题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。
本公开实施例提供的TCI状态确定方法可应用于图1所示的无线通信***中。参阅图1所示，该无线通信***中包括终端和网络设备。终端通过无线资源与网络设备相连接，并进行数据的发送与接收。
可以理解的是，图1所示的无线通信***仅是进行示意性说明，无线通信***中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信***中包括的网络设备数目和终端数目不做限定。
进一步可以理解的是，本公开实施例的无线通信***，是一种提供无线通信功能的网络。无线通信***可以采用不同的通信技术，例如码分多址(code division multiple access,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense Multiple Access with Collision Avoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。
进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备 可以是：基站、演进型基站(evolved node B，eNB)、家庭基站、无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为NR***中的gNB，或者，还可以是构成基站的组件或一部分设备等。当为车联网(V2X)通信***时，网络设备还可以是车载设备。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。
进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(User Equipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信***时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。
本公开中网络设备与终端之间基于波束进行数据传输。基于波束进行数据传输过程中，网络设备(例如基站)可以使用多个TRP(多个TRP也称为Multi-TRP)为终端发送PDCCH。相关技术中，网络设备(例如基站)使用一个TRP为终端发送PDCCH时，为终端配置接收该PDCCH的TCI状态。例如，配置方法为：为终端配置一个CORESET比如CORESET#1，且配置终端接收该CORESET#1资源中的PDCCH时对应使用的TCI状态为TCI#1。并为终端配置一个搜索空间集(Search Space set，SS set)，与CORESET#1关联。终端在接收SS set中resource上的PDCCH时，就使用TCI#1对应的波束进行接收。目前每个SS set只能与一个CORESET关联，每个CORESET只配置一个TCI状态(TCI状态也称为TCI state)。
本公开中网络设备与终端之间基于波束进行数据传输。基于波束进行数据传输过程中，当网络设备(例如基站)使用多个TRP(多个TRP也称为Multi-TRP)为终端发送PDCCH时，不同的TRP使用不同的波束发送。其中，多个TRP可以发送相同的PDCCH。
为了实现多个TRP发送同样的PDCCH，目前有方法：配置两个CORESET，每个CORESET对应配置一个TCI状态，并分别配置SS set与两个CORESET分别关联。即配置了两个SS set，关联不同的CORESET和对应不同的TCI状态。其中，两个具有关联关系的SS set的PDCCH candidate之间也有关联关系。例如，SS set#1和SS set#2关联，则SS set#1中的PDCCH candidate#i与SS set#2的PDCCH candidate#i关联，即index相同的 两个PDCCH candidate用于发送同一个DCI。
其中，多个TRP发送同样的PDCCH的一种应用场景为Multi-TRP PDCCH repetition。Multi-TRP PDCCH repetition中，配置两个CORESET，并配置CORESET对应的TCI状态。每个CORESET对应配置一个TCI状态，并配置两个具有链接关系的SS set，关联不同的CORESET和对应不同的TCI状态。其中，具有链接关系的两个SS set可以理解为是两个SS set中PDCCH candidate index一样的两个PDCCH candidate用于发送一个DCI。
传统方法中，支持S-DCI机制指示TCI状态，即所有DCI对应的CORESET的CORESETPoolIndex是一样的。相关技术中，还支持多DCI(M-DCI)机制指示TCI状态，即不同DCI对应的CORESET的CORESETPoolIndex可能是不一样的。
以下首先对S-DCI机制和M-DCI机制进行说明。
S-DCI机制中，所有CORESET对应一个CORESETPoolIndex 0或没有配置CORESETPoolIndex值。DCI信令中的TCI域的codepoint中每个codepoint可以最多对应两个TCI state，其对应关系由媒体接入控制(Medium Access Control，MAC)控制单元(Control element，CE)确定，不需要区分不同TRP。图2示出了一种S-DCI机制下MAC CE格式示意图。如图2所示，TCI state ID下面有两个脚标i，j。i标识这个TCI state ID对应的DCI中TCI field 3bit的codepoint，比如i为0对应codepoint 000；i为1对应codepoint 001……。脚标j标识该TCI state ID为第i个codepoint对应的至少一个TCI state ID中的第j个。比如j为1标识第一个，j为2标识第二个。如脚标为0，1标识对应codepoint 000的第一个TCI state ID。参阅图2所示，S-DCI机制下，每个codepoint可以对应最多两个TCI state，即对应不同的TRP。
M-DCI机制中，有的CORESET对应CORESETPoolIndex 0，有的CORESET对应CORESETPoolIndex 1。DCI信令中的TCI域的codepoint中每个codepoint可以最多对应一个TCI state，不同CORESETPoolIndex中的CORESET的TCI域中的codepoint对应的TCI state由不同的MAC CE确定。M-DCI机制中，MAC CE包含CORESETPoolIndex和需要激活的最多8个TCI state。图3示出了一种M-DCI机制下MAC CE格式示意图。如图3所示，MAC CE包含CORESETPoolIndex。MAC CE指示的是包含的CORESETPoolIndex所包含的至少一个CORESET的DCI的TCI field的codepoint对应的TCI state。图3中给出了很多个T i，i标识RRC信令中的TCI state ID，若T i的比特位置为1，则标识激活该TCI state ID。比如对于CORESETPoolIndex 0，MAC CE激活了TCI state#0，TCI state#4，TCI state#5，TCI state#12，TCI state#14，TCI state#26，TCI state#34，TCI state#40，分别对应CORESET#0和CORESET#1(这两个CORESET的CORESETPoolIndex为0)的DCI 的TCI field的codepoint 000,001,010,011,100,101,110,111。再比如对于CORESETPoolIndex 1，MAC CE激活了TCI state#70，TCI state#74，TCI state#75，TCI state#82，TCI state#84，TCI state#96，TCI state#104，TCI state#108，分别对应CORESET#2和CORESET#3(这两个CORESET的CORESETPoolIndex为1)的DCI的TCI field的codepoint。
当用于PDCCH repetition传输的多个具有链接关系的SS set所对应的CORESET的CORESETPoolIndex不一样时，该具有链接关系的多个SS set中的PDCCH candidate携带的DCI中的TCI域的codepoint对应的TCI状态如何配置，是采用S-DCI机制，还是采用M-DCI的机制，是需要解决的问题。
本公开实施例提供一种TCI状态确定方法，以给出用于PDCCH repetition的两个PDCCH candidate对应的CORESET的CORESETPoolIndex不同时，其DCI中TCI域包含的codepoint对应的激活TCI state的指示。
图4是根据一示例性实施例示出的一种TCI状态确定方法的流程图，如图4所示，TCI状态确定方法由终端执行，包括以下步骤。
在步骤S11中，接收第一配置信息，第一配置信息用于配置具有链接关系的至少两个SS set，至少两个SS set中的其中两个SS set对应的CORESET的CORESETPoolIndex不同。
本公开实施例中，两个SS set具有链接关系可以理解为是两个SS set中PDCCH candidate index一样的两个PDCCH candidate用于发送一个DCI，也可以理解为是两个SS set用于PDCCH repetition。
在步骤S12中，确定待接收的MAC CE为第一MAC CE。
其中，第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的至少一个TCI状态，至少一个codepoint承载在DCI的TCI域中，DCI由具有链接关系的至少两个SS set中的PDCCH candidate传输。
本公开实施例中，当用于PDCCH repetition传输的多个具有链接关系的SS set所对应的CORESET的CORESETPoolIndex不一样时，通过第一MAC CE指示DCI中TCI field包含的codepoint对应的TCI state。
本公开实施例以下将对第一MAC CE的确定过程进行说明。
一种实施方式中，网络设备可以配置用于指示第一MAC CE的配置信息，以下称为第二配置信息。
图5是根据一示例性实施例示出的一种确定第一MAC CE的方法流程图，如图5所示，包括以下步骤。
在步骤S21中，确定第二配置信息。
在步骤S22中，基于第二配置信息，确定待接收的MAC CE为第一MAC CE。
本公开实施例中，第二配置信息由网络设备配置，并用于指示第一MAC CE。终端接收网络设备发送的第二配置信息，以确定第一MAC CE。
其中，第二配置信息指示以下至少一项：MAC CE中包括的CORESETPoolIndex的指定索引值；MAC CE中包括的指定比特。
一种实施方式中，若终端接收到的MAC CE满足第二配置信息指示的以下A和B至少一项，确定待接收的MAC CE为第一MAC CE：
A：MAC CE中包括的CORESETPoolIndex具有指定索引值。
B：MAC CE中包括指定比特。
一示例中，指定索引值可以是与任意其它SS set不具有链接关系的SS set对应的CORESET的CORESETPoolIndex，以下称为第一索引值。例如第一索引值可以是0或1。
另一示例中，指定索引值也可以是不同于与任意其它SS set不具有链接关系的SS set对应的CORESET的CORESETPoolIndex，以下称为第二索引值。例如，第二索引值可以是为具有链接关系的两个SS set分配的新的CORESETPoolIndex。例如第二索引值可以是2。当具有链接关系的两个SS set中任意一个SS set关联的CORESET还包含独立SS set时，该CORESET的CORESETPoolIndex还是为0或1，而只是具有链接关系的两个SS set的CORESETPoolIndex为2。其中，独立SS set即与任意其它SS set不具有链接关系的SS set。
本公开实施例中，当MAC CE中的CORESETPoolIndex为指定索引值，比如为0或1时或新引入的2，该MAC CE为第一MAC CE。此种方式一方面可以理解为是对应图3所示的M-DCI方式下的MAC CE。
其中，指定比特可以用于指示MAC CE是否为第一MAC CE。
一种实施方式中，第一配置信息配置一组具有链接关系的至少两个SS set，指定比特用于指示待接收的MAC CE是否为第一MAC CE。一示例中，若只有一组用于PDCCH repetition的两个具有链接关系的SS set，用于指示第一MAC CE的指定比特指示是或否即可。
另一种实施方式中，第一配置信息配置多组具有链接关系的至少两个SS set，指定比特用于指示具有链接关系的至少两个SS set所属组的组标识。其中，组标识通过无线资源控制(Radio Resource Control，RRC)信令配置或基于SS set组中SS set ID较小的SS set来确定，或基于SS set组对应的CORESET组的CORESET ID较小的CORESET来确定。一示例中，若有多组用于PDCCH repetition的两个具有链接关系的SS set时，用于指示第 一MAC CE的指定比特需要指示某组具有链接关系的SS set的组标识。
本公开实施例中，当MAC CE中包括用于指示第一MAC CE的指定比特时，确定MAC CE为第一MAC CE的方式一方面可以是对应图2所示的S-DCI方式下的MAC CE。另一方面，本公开实施例中的第一MAC CE可以新引入的MAC CE设计。在该新引入的MAC CE中可以是在图2中所示的MAC CE中引入CORESETPoolIndex。当CORESETPoolIndex为0或1时，每个codepoint只激活一个TCI state。当CORESETPoolIndex为2时，可以每个codepoint激活两个TCI state。该新引入的MAC CE设计可以理解为是用于具有链接关系的SS set的MAC CE。本公开实施例中，指定比特也可以是CORESET对应的CORESETPoolIndex，比如第一组SS set对应的CORESETPoolIndex为2，第二组SS set对应的CORESETPoolIndex为3，如此下去。
本公开实施例提供的TCI状态确定方法中上述涉及的第二配置信息一方面可以是基于RRC信令确定的，即，终端基于承载在RRC信令中的第二配置信息确定第一MAC CE。例如，网络通过RRC信令指示终端当MAC CE中的CORESETPoolIndex为指定索引值，比如为0或1时或新引入的值2，该MAC CE为第一MAC CE。网络通过RRC信令指示终端MAC CE中包含指定比特，该指定比特用于指示该MAC CE是否为第一MAC CE。
本公开实施例提供的TCI状态确定方法中上述涉及的第二配置信息另一方面可以是基于默认规则确定的，即，终端基于协议默认的第二配置信息确定第一MAC CE。例如，当MAC CE中的CORESETPoolIndex为0或1时或新引入的值2时，该MAC CE为第一MAC CE。或该MAC CE中包括指定比特，指定比特指示为是时，该MAC CE为第一MAC CE；或该MAC CE中包括指定比特，指定比特指示SS set组的组标识时，该MAC CE为第一MAC CE。
本公开实施例提供的TCI状态确定方法中，终端可以基于默认规则确定待接收的MAC CE为第一MAC CE。
其中，默认规则可以包括如下指示一项：
A：媒体接入控制单元中的CORESETPoolIndex为至少两个SS set中SS set标识最小的SS set所对应的CORESET的CORESETPoolIndex值；
B：媒体接入控制单元中的CORESETPoolIndex为至少两个SS set对应的CORESET中CORESET标识较小的CORESET对应的CORESETPoolIndex值；
C：媒体接入控制单元中的CORESETPoolIndex值为第一索引值和第二索引值中的至少一个索引值。其中，第一索引值为0或1，第二索引值为新引入的CORESETPoolIndex值2。
本公开实施例中，终端可以基于第二配置信息，和/或默认规则，确定第一MAC CE。
进一步的，本公开实施例中，终端在后续可以接收第一MAC CE，该第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的最多一个TCI状态，或者用于指示至少一个codepoint中每一codepoint所对应的最多两个TCI状态，以基于接收到的第一MAC CE确定DCI中TCI域包含的codepoint对应的激活TCI state。
更进一步的，终端可以接收DCI，并确定DCI中TCI域所包括的codepoint，以下称为第一codepoint。终端基于第一MAC CE指示的TCI状态与codepoint之间的对应关系，可以确定出第一codepoint对应的TCI状态，进而得到DCI中TCI域包含的codepoint对应的激活TCI state。
图6是根据一示例性实施例示出的一种TCI状态确定方法流程图，如图6所示，TCI状态确定方法由终端执行，包括以下步骤。
在步骤S31中，接收第一MAC CE，该第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的最多一个TCI状态，或者用于指示至少一个codepoint中每一codepoint所对应的最多两个TCI状态。
在步骤S32中，接收DCI，并确定DCI中TCI域所包括的第一codepoint。
在步骤S33中，基于第一MAC CE指示的TCI状态与codepoint之间的对应关系，确定第一codepoint对应的TCI状态。
例如，第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的最多一个TCI状态，可以基于图3所示的M-DCI机制，确定DCI中TCI域包含的codepoint对应的激活TCI state。再例如，第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的最多两个TCI状态，可以基于图2所示的M-DCI机制，确定DCI中TCI域包含的codepoint对应的激活TCI state。
一种实施方式中，第一MAC CE用于指示至少一个codepoint中的至少一个codepoint所对应的至少两个TCI状态，该至少两个TCI状态中的每个TCI状态用于上行传输和/或下行传输。即，该至少两个TCI状态都用于下行，或该至少两个TCI状态都用于上行，或该至少两个TCI状态中有的用于上行有的用于下行，或该至少两个TCI状态都同时用于上行和下行。
可以理解的是，本公开实施例中，下行包含下行信道和/或下行信号。下行信道包含以下至少一项：终端专用的PDCCH(UE dedicated PDCCH)，非终端专用的PDCCH(non-UE dedicated PDCCH)，终端专用的PDSCH(UE dedicated PDSCH)，非终端专用的PDSCH(non-UE dedicated PDSCH)，物理广播信道(Physical broadcast channel，PBCH)。下行信 号包含以下至少一项：SSB，信道状态信息参考信号(CSI reference signal，CSI-RS)(用于信道状态信息(Channel State Information，CSI)测量，和/或，用于波束管理(beam management))，跟踪参考信号(tracking reference signal，TRS)，相位参考信号(Phase reference signal，PRS)，解调参考信号(Demodulation Reference Signal，DMRS)。其中，下行信号可以是周期性的，半持续调度(semi-persistent)的，或非周期性的。

基于相同的构思，本公开实施例还提供一种TCI状态确定方法，该TCI状态确定方法由网络设备执行。
图7是根据一示例性实施例示出的一种TCI状态确定方法流程图，如图7所示，TCI状态确定方法由网络设备执行，包括以下步骤。
在步骤S41中，发送第一配置信息，第一配置信息用于配置具有链接关系的至少两个SS set，至少两个SS set中的其中两个SS set对应的CORESET的CORESETPoolIndex不同。
在步骤S42中，发送第一MAC CE，第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的至少一个TCI状态，至少一个codepoint承载在DCI的TCI域中，DCI由具有链接关系的至少两个SS set中的PDCCH candidate传输。
一种实施方式中，网络设备可以发送第二配置信息，第二配置信息用于指示第一MAC CE。
其中，第二配置信息指示以下至少一项：MAC CE中包括的CORESETPoolIndex的指定索引值；MAC CE中包括的指定比特。
一种实施方式中，指定索引值包括第一索引值或第二索引值。第一索引值为与任意其它SS set不具有链接关系的SS set对应的CORESET的CORESETPoolIndex。例如第一索引值可以是0或1。第二索引值不同于与任意其它SS set不具有链接关系的SS set对应的CORESET的CORESETPoolIndex。例如第二索引值可以是2。
其中，当具有链接关系的两个SS set中任意一个SS set关联的CORESET还包含独立SS set时，该CORESET的CORESETPoolIndex还是为0或1，而只是具有链接关系的两个 SS set的CORESETPoolIndex为2。其中，独立SS set即与任意其它SS set不具有链接关系的SS set。
一种实施方式中，指定比特用于指示以下至少一项：
第一配置信息配置一组具有链接关系的至少两个SS set，指定比特用于指示待接收的MAC CE是否为第一MAC CE；第一配置信息配置多组具有链接关系的至少两个SS set，指定比特用于指示具有链接关系的至少两个SS set所属组的组标识。
本公开实施例中，当MAC CE中包括用于指示第一MAC CE的指定比特时，确定MAC CE为第一MAC CE的方式一方面可以是对应图2所示的S-DCI方式下的MAC CE。另一方面，本公开实施例中的第一MAC CE可以新引入的MAC CE设计。在该新引入的MAC CE中可以是在图2中所示的MAC CE中引入CORESETPoolIndex。当CORESETPoolIndex为0或1时，每个codepoint只激活一个TCI state。当CORESETPoolIndex为2时，可以每个codepoint激活两个TCI state。该新引入的MAC CE设计可以理解为是用于具有链接关系的SS set的MAC CE。本公开实施例中，指定比特也可以是CORESET对应的CORESETPoolIndex，比如第一组SS set对应的CORESETPoolIndex为2，第二组SS set对应的CORESETPoolIndex为3，如此下去。
一种实施方式中，网络设备可以基于RRC信令发送第二配置信息。
一种实施方式中，第一MAC CE用于指示至少一个codepoint中每一codepoint所对应的最多一个TCI状态，或者用于指示至少一个codepoint中每一codepoint所对应的最多两个TCI状态。
一种实施方式中，第一MAC CE用于指示至少一个codepoint中的至少一个codepoint所对应的至少两个TCI状态；至少两个TCI状态中的每个TCI状态用于上行传输和/或下行传输。即，该至少两个TCI状态都用于下行，或该至少两个TCI状态都用于上行，或该至少两个TCI状态中有的用于上行有的用于下行，或该至少两个TCI状态都同时用于上行和下行。
其中，下行包含下行信道和/或下行信号。上行包括上行信道和/或上行信号。
可以理解的是，本公开实施例中由网络设备执行的TCI状态确定方法，是与终端执行TCI状态确定方法相对应的，对于一些描述不够详尽的地方，可以参阅终端侧涉及的一些实施方案，在此不再赘述。
进一步可以理解的是，本公开实施例提供的TCI状态确定方法适用于终端与网络设备交互实现TCI配置的过程。
需要说明的是，本领域内技术人员可以理解，本公开实施例上述涉及的各种实施方式 /实施例中可以配合前述的实施例使用，也可以是独立使用。无论是单独使用还是配合前述的实施例一起使用，其实现原理类似。本公开实施中，部分实施例中是以一起使用的实施方式进行说明的。当然，本领域内技术人员可以理解，这样的举例说明并非对本公开实施例的限定。
基于相同的构思，本公开实施例还提供一种TCI状态确定装置。
可以理解的是，本公开实施例提供的TCI状态确定装置为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本公开实施例中所公开的各示例的单元及算法步骤，本公开实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本公开实施例的技术方案的范围。
