背景技术
目前，为了解决当前独立波束指示的方式，增加了系统的复杂度和信令指示开销的问题，引入了采用一个波束指示信令指示多个信道波束的方法，其通过媒体接入控制(Media Access Control，MAC)-控制单元(Control Element，CE)激活一组传输配置指示(Transmission Configuration Indicator，TCI)状态，再使用下行控制信息(Downlink Control Information，DCI)指示其中的一个激活的TCI状态。但是，当指示多传输点(Transmission and Reception Point，TRP)传输时，波束指示信令需要指示不同TRP(对应不同链路)的波束；如何使用波束指示信令指示多TRP传输，目前还无法支持实现。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，并不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本公开实施例中术语“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例中术语“多个”是指两个或两个以上，其它量词与之类似。
在此说明，本公开实施例提供的技术方案可以适用于多种系统，尤其是 第五代移动通信(5th-Generation，5G)系统。例如适用的系统可以是全球移动通讯(global system of mobile communication，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)通用分组无线业务(general packet radio service，GPRS)系统、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)系统、高级长期演进(long term evolution advanced，LTE-A)系统、通用移动系统(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)系统、5G新空口(New Radio，NR)系统等。这多种系统中均包括终端设备和网络设备。系统中还可以包括核心网部分，例如演进的分组系统(Evloved Packet System，EPS)、5G系统(5G System，5GS)等。
图1示出本公开实施例可应用的一种无线通信系统的框图。无线通信系统包括终端设备和网络设备。终端设备也可称为终端，在此不作限定。
本公开实施例涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中，终端设备的名称可能也不相同，例如在5G系统中，终端设备可以称为用户设备(User Equipment，UE)。无线终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network，CN)进行通信，无线终端设备可以是移动终端设备，如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user  agent)、用户装置(user device)，本公开实施例中并不限定。
本公开实施例涉及的网络设备，可以是基站，该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同，基站又可以称为接入点，或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备，或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol，IP)分组进行相互更换，作为无线终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如，本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications，GSM)或码分多址接入(Code Division Multiple Access，CDMA)中的网络设备(Base Transceiver Station，BTS)，也可以是带宽码分多址接入(Wide-band Code Division Multiple Access，WCDMA)中的网络设备(NodeB)，还可以是长期演进(long term evolution，LTE)系统中的演进型网络设备(evolutional Node B，eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB)，也可以是家庭演进基站(Home evolved Node B，HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等，本公开实施例中并不限定。在一些网络结构中，网络设备可以包括集中单元(Centralized Unit，CU)节点和分布单元(Distributed Unit，DU)节点，集中单元和分布单元也可以地理上分开布置。
网络设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output，MIMO)传输，MIMO传输可以是单用户MIMO(Single User MIMO，SU-MIMO)或多用户MIMO(Multiple User MIMO，MU-MIMO)。根据根天线组合的形态和数量，MIMO传输可以是二维MIMO(2Dimission MIMO，2D-MIMO)、三维MIMO(3Dimission MIMO，3D-MIMO)、全维度MIMO(Full Dimension，FD-MIMO)或超大规模MIMO(massive-MIMO)，也可以是分集传输或预编码传输或波束赋形传输等。
下面首先对本公开实施例提供的方案涉及的内容进行介绍。
在NR(新空口)系统中，下行信道包括物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和物理下行控制信道(Physical Downlink  Control Channel，PDCCH)，上行信道包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)和物理上行控制信道(Physical Uplink Control Channel，PUCCH)。对于高频传输(NR中的FR2频段)，由于传输范围受限，通常上下行信道会经过波束赋形后进行传输以增强覆盖。赋形波束的方向可以通过上下行参考信号的波束扫描确定，例如使用不同方向的信道状态信息(Channel State Information，CSI)-参考信号(Reference Signal，RS)或者探测参考信号(Sounding Reference Signal，SRS)进行波束扫描，选择波束质量最好的参考信号所在方向用于上行或者下行传输。确定了不同信道的波束方向，需要使用信令指示信道传输时的波束，即波束指示。目前，对于PUCCH，基站通过高层信令SpatialRelationInfo半静态的配置给终端多个波束方向，并通过MAC(媒体接入控制)-CE(控制单元)指示激活其中的一个。对于PUSCH，基站选择的上行波束是由动态信令DCI(下行控制信息)中SRS资源索引(SRS Resource Index,SRI)域所指的SRS资源的SpatialRelationInfo间接指示的。对于PDCCH信道，基站通过高层信令为每个控制资源集(CORESET)配置多个TCI状态(state/State)，并通过MAC-CE指示激活其中的一个。对于PDSCH信道，基站通过DCI信令中的TCI域指示一个TCI state，表示信道的波束方向。
不同的信道使用不同的波束指示信令，且各个信道独立进行波束指示。这样不同的信道可能使用各自不同的波束传输。而实际应用中的一个重要场景是多个信道使用相同的波束方向。例如，用于资源调度的PDCCH和传输用户数据的PDSCH之间使用相同的波束方向传输；上行控制信道PUCCH和上行数据信道PUSCH也会使用相同的波束方向。当波束互易性存在时，上行信道和下行信道也将使用同一个波束方向。此时，当前这种独立波束指示的方式，增加了系统的复杂度和信令指示开销。为了克服以上问题，目前引入采用一个波束指示信令指示多个信道波束的方法，其通过MAC-CE激活一组TCI状态，再使用DCI指示其中的一个激活的TCI状态。当上下行信道互易时，波束指示信令所指示的波束可以既用于上行信道也用于下行信道；当发生由于人体遮挡而产生的最大允许辐射(Maximum Permissible Exposure，MPE)问题或者终端需要切换上行波束时，上行信道将使用与下行信道不同 的波束，这样所述波束指示信令需要分别指示上行信道波束和下行信道波束。
基于以上，本公开实施例提供了一种信息传输方法、装置、网络设备及终端，用以解决相关技术中针对多TRP传输的信息传输方案无法支持实现的问题。其中，方法、装置、网络设备及终端是基于同一申请构思的，由于方法、装置、网络设备及终端解决问题的原理相似，因此方法、装置、网络设备及终端的实施可以相互参见，重复之处不再赘述。

下面对本公开实施例提供的方案进行具体举例。
举例1：
基站通过DCI信令或第一MAC-CE信令为终端指示2个TCI状态(对应于向终端发送上述第一指示信令，TCI状态对应于上述TCI状态取值)。基站通过RRC信令为终端配置5个CORESET，分别表示为CORESET#0,CORESET#1,…,CORESET#4。同时，基站为终端配置所述DCI指示的TCI状态与CORESET的映射关系(对应于上述第一对应关系)，用于所述CORESET的传输。所述映射关系可以通过MAC-CE或RRC信令配置。(1)一种方式是，RRC信令在每个CORESET的配置中，通过配置TCI_usage(用法，可理解为选择；对应于上述TCI状态取值指示)指示其使用2个TCI状态中的第一个还是第二个，或者使用2个TCI状态。例如，采用以下配置：
其表示CORESET#2使用指示的第一个TCI状态。或者采用以下配置：
其表示CORESET#2既使用指示的第一个TCI状态，也使用指示的第二个TCI状态。其可应用于高铁场景。
(2)另外一种实现方式是通过RRC配置CORESET组(即CORESET分组或CORESET集合)，基站为终端配置TCI状态(对应于上述TCI状态指示)与CORESET组的映射关系(对应于上述第一对应关系)。分组1包括{CORESET#0,CORESET#1,CORESET#2},分组2包括{CORESET#3,CORESET#4}。分组1中可配置使用第一个TCI状态和第二个TCI状态，分组2中可配置使用第二个TCI状态。此外也可以通过系统约定，分组1中的CORESET使用两个TCI状态，分组2中使用第一个TCI状态。此时，不需要在分组中配置使用的TCI状态。CORESET组中的CORESET ID可以通过MAC-CE更新。也就是：一种是基站在CORESET组的配置中携带使用的TCI状态(取值指示)的指示信息；一种是系统约定，根据CORESET ID就可以知道使用的TCI状态(取值指示)。
(3)另一种实现方式是，RRC信令配置指示的第一个TCI状态(取值指示)对应的CORESET集合，和指示的第二个TCI状态对应的CORESET集合。例如，RRC配置第一个TCI状态关联{CORESET#0,CORESET#1},第二个TCI状态关联{CORESET#2,CORESET#3,CORESET#4}。也可以是RRC配置第一个TCI状态关联{CORESET#0,CORESET#1,CORESET#3},第二个TCI状态关联{CORESET#2,CORESET#3,CORESET#4}。这里CORESET#3使用两个TCI状态，可用于高铁场景。
(4)另一种实现方式是使用MAC-CE信令指示所述关联关系(即TCI状态与CORESET集合的关联关系)。例如，在激活TCI状态的MAC-CE信令中，增加每个TCI状态位关联的CORESET集合(即CORESET分组，这种情况下不需要前述的TCI_usage参数配置)，如下：
表1MAC-CE信令中激活的TCI状态(TCI状态与集合的对应关系)
其中，激活的TCI状态-1关联{CORESET#0,CORESET#1}，激活的TCI状态-2关联{CORESET#2,CORESET#3,CORESET#4}。当DCI信令指示一个码点“001”时，CORESET#0和CORESET#1使用第一个TCI状态TCI-State9传输；CORESET#2，CORESET#3和CORESET#4使用第二个TCI状态TCI-State10传输。或者，配置如下：
表2MAC-CE信令中激活的TCI状态
其中CORESET#4使用两个TCI状态传输，可应用于高铁场景。
(5)另一种实现方式是MAC-CE指示每个CORESET或者每个CORESET分组的TCI状态(取值)。例如RRC为终端配置3个CORESET。 如表3，MAC-CE激活信令中为每个CORESET配置了对应的TCI状态。其中CORESET#1和CORESET#2的TCI状态相同，表示其使用相同的TRP传输。
表3MAC-CE信令中激活的TCI状态
(6)另外一种实现方式是采用DCI信令指示。在基站指示TCI状态(取值)的DCI信令中可包含一个TCI使用关联域，指示不同CORESET或不同CORESET分组使用的TCI状态。例如，将CORESET分组，其中分组1包括{CORESET#0,CORESET#1,CORESET#2},分组2包括{CORESET#3,CORESET#4}；可以使用RRC信令进行分组配置。在DCI中，包含TCI域(对应于上述TCI状态取值的指示域)，其用于指示TCI状态。同时DCI中还可包含TCI使用关联域。1)一种实现方式是TCI使用关联域采用码点状态的方式指示，例如如下表4所示：
表4
其中，TCI使用关联域可包含2bit，”00”表示分组1使用TCI域指示的第一个TCI状态(取值)和分组2使用TCI域指示的第二个TCI状态，”01”表示分组1使用TCI域指示的第二个TCI状态和分组2使用TCI域指示的第一个TCI状态，”10”表示分组1和分组2均使用TCI域指示的第一个TCI状态，”11”表示分组1和分组2均使用TCI域指示的第二个TCI状态。也可以 通过码点，指示分组1使用两个TCI状态，或者分组2使用两个TCI状态等。假设”011”对应TCI-State25和TCI-State29，可根据TCI使用关联域指示确定：分组1使用TCI-State25，分组2使用TCI-State29。
2)另外一种实现方式是，DCI中的TCI使用关联域采用位图(bitmap)的方式，分别指示每个CORESET使用的TCI状态(取值)。如下表5：
表5
TCI使用关联域包含5bit。每个bit分别对应一个CORESET，取0表示使用第一个TCI状态，取1表示使用第二个TCI状态；则假设”011”对应TCI-State25和TCI-State29，确定：CORESET#0,CORESET#1,CORESET#3使用TCI-State25，CORESET#2和CORESET#4使用TCI-State29。
举例2：
基站为终端配置PUCCH资源组，每个PUCCH资源组中包含一个或多个PUCCH资源，也可以是基站为每个PUCCH资源配置资源组的编号。所述的资源组内的PUCCH资源可以通过MAC-CE信令进行更新。基站通过DCI信令或第一MAC-CE信令为终端指示2个TCI状态(对应于向终端发送上述第一指示信令，TCI状态对应于上述TCI状态取值)。终端需要确定基站指示的TCI状态与PUCCH资源组或PUCCH资源的对应关系(对应于上述第一对应关系)，使得每个PUCCH资源使用其相对应的TCI状态进行传输。
下面提供具体实现方式举例：
(1)一种实现方式是，系统预定义PUCCH资源组与TCI状态的对应关系。例如，基站为终端配置2个PUCCH资源组，且约定资源组1对应基站指示的2个TCI状态(取值)，资源组2对应基站指示的第一个TCI状态。若基站指示了TCI-State9和TCI-State10，资源组1中的每个PUCCH资源将使用这两个状态进行传输。具体的传输可以是，资源组1中的一个PUCCH资源的多个传输时机依次循环映射到TCI_State9对应的发送波束(表示为#1)和TCI_State10对应的发送波束(表示为#2)。以4次传输为例，发送波束的映射图样是#1#2#1#2，对应向两个TRP传输。而对于资源组2中的每个 PUCCH资源，仅使用TCI_State9对应的发送波束进行传输，对应单TRP传输。还可以是基站为终端配置3个PUCCH资源组，且约定资源组1对应基站指示的2个TCI状态，资源组2对应基站指示的第一个TCI状态，资源组3对应基站指示的第二个TCI状态。
(2)另一种实现方式是使用MAC-CE信令指示PUCCH资源组(即PUCCH分组)与TCI状态的对应关系。例如，在激活TCI状态的MAC-CE信令中，增加每个TCI状态位关联的PUCCH资源组。具体与举例1类似(参见表1至表3的相关内容，CORESET分组对应PUCCH资源组)，不再赘述。
(3)另外一种实现方式是采用DCI信令指示。在基站指示TCI状态的DCI信令中可包含一个TCI使用关联域，指示不同PUCCH分组使用的TCI状态(取值)。具体与举例1类似(类似于例如，将CORESET分组，其中分组1包括{CORESET#0,CORESET#1,CORESET#2},分组2包括{CORESET#3,CORESET#4}。可以使用RRC信令进行分组配置。在DCI中，包含TCI域(对应于上述TCI状态取值的指示域)，其用于指示TCI状态。同时DCI中还可包含TCI使用关联域。一种实现方式是TCI使用关联域采用码点状态的方式指示；CORESET分组对应PUCCH资源组)，不再赘述。
(4)另外一种实现方式是采用DCI信令指示。在基站指示TCI状态的DCI信令中包含一个TCI使用关联域，指示其用于上行ACK或NACK反馈的PUCCH资源使用的TCI状态。具体与举例1类似(类似于在基站指示TCI状态的DCI信令中可包含一个TCI使用关联域，指示不同CORESET或不同CORESET分组使用的TCI状态；PUCCH资源对应CORESET)，不再赘述。
(5)本举例也可以在每个PUCCH资源或每个PUCCH资源集合中配置其使用的TCI状态(比如没有TCI1对应的状态组或没有TCI2对应的状态组，将TCI状态直接配置在每个资源和资源集合中；TCI状态对应于上述TCI状态取值指示)。例如如下：

其表示所述PUCCH资源使用第一个TCI状态和第二个TCI状态。
举例3：
基站通过DCI信令或第一MAC-CE信令为终端指示2个TCI状态(对应于向终端发送上述第一指示信令，TCI状态对应于上述TCI状态取值)，用于PUSCH的传输；需要指示TCI状态与PUSCH传输时机的映射关系(对应于上述第一对应关系)。
下面提供具体实现方式举例：
(1)一种实现方式是在每个SRS资源集或每个SRS资源中配置其使用的TCI状态(PUSCH传输时机与SRS资源集存在对应关系)。如：
其表示SRS资源集使用第一个TCI状态。根据系统预定义的PUSCH传输时机与SRS资源集存在对应关系实现使用不同TCI状态的重复传输。
(2)另一种实现方式是在PUSCH配置中配置其使用的TCI状态(取值指示)。如下表示PUSCH使用第一个TCI状态和第二个TCI状态进行mTRP(多TRP)传输(系统可固定传输时机与TCI状态的关系)，如下配置。这种方式可以用于免授权PUSCH的重复传输。系统预定义第一个重复传输使用第一个TCI状态，第二个重复传输使用第二个TCI状态。
PUSCH-Config(配置)::＝               SEQUENCE{
TCI_usage                        1，2
}。
(3)另一种实现方式是系统预定义DCI中的2比特SRS resource set(s)域中的码点与TCI状态(取值指示)的对应关系。例如系统预定义以下(参见下表6)的映射关系。其中的“00”表示单TRP传输，且每个传输时机均使用基站指示的第一个TCI状态进行PUSCH的传输。其中的“10”表示多TRP传输，第一个传输时机使用第一个TCI状态进行PUSCH的传输，第二个传输时机使用第二个TCI状态进行PUSCH的传输，依次类推。其中也可以不包含SRS资源集域这一列。
表6

其中，TPMI即Transmission Pre-coding Matrix Indicator，表示传输预编码矩阵指示。
(4)另一种实现方式是使用MAC-CE信令指示所述关联关系(即TCI状态与SRS资源集的对应关系)。例如，在激活TCI状态的MAC-CE信令中，增加每个TCI状态位关联的SRS资源集(SRS resource set)。具体与举例1类似(参见表1至表3的相关内容，CORESET分组对应SRS资源集)，不再赘述。
举例4：
(1)基站通过DCI信令为终端指示2个TCI状态(对应于向终端发送上述第一指示信令，TCI状态对应于上述TCI状态取值)。所述DCI信令中包括sTRP(单TRP)和/或mTRP(多TRP)指示域。所述指示域包含2bit，系统预定义指示域中的码点与TCI状态的对应关系(对应于上述第一对应关系)。一种对应关系可以如下表7：
表7

根据上述对应关系，基站采用1个TRP或两个TRP传输PDSCH。
(2)另一种实现方式是，基站通过DCI信令为终端指示1个或2个TCI状态(取值)。同时所述DCI信令中包含sTRP和/或mTRP指示域。系统预定义指示域中的码点与TCI状态的对应关系，如下表8所示。当基站指示2个TCI状态时，与上表的含义相同，即使用sTRP或mTRP传输。而当基站指示1个TCI状态时，当指示’10’或‘11’时，其表示仍采用mTRP传输，且更新(即更换)当前两个TCI状态中的一个TCI状态。
表8
举例5：
当基站为终端配置了CORESETPoolIndex时，表示使用M-DCI(多DCI)进行调度(对应于向终端发送上述第一指示信令)。基站可以指示TCI状态(取值指示)与CORESETPoolIndex的对应关系(对应于上述第一对应关系)。(1)一种方式可以在激活TCI状态的MAC-CE信令中，配置每个TCI状态对应的CORESETPoolIndex；也可以由RRC在每个CORESET下配置对应的TCI状态，如对应第一个TCI状态或对应第二个TCI状态，同时要求相同CORESETPoolIndex对应的CORESET的TCI状态相同；也可以在TCI指示 的DCI中，配置两个TCI指示域(对应于上述TCI状态取值的指示域)，如下表9所示，所述第一个TCI指示域指示CORESETPoolIndex0对应的TCI状态，所述第二个TCI指示域指示CORESETPoolIndex1对应的TCI状态。当仅指示一个CORESETPoolIndex对应的TCI状态时，另一个TCI指示域置为无效。
表9
(2)另一种方式是在TCI指示的DCI中，指示TCI状态(取值)和CORESETPoolIndex信息。例如如下表10：
表10
其表示，所述TCI域指示的TCI状态应用于CORESETPoolIndex0对应的CORESET及其调度的PDSCH。
举例6：
为了实现上行多panel同时传输，终端需要将基站指示的TCI状态(对应于上述第一指示信令，TCI状态对应于上述TCI状态取值)对应到终端的不同panel(对应于终端根据上述第一对应关系确定panel的TCI状态取值)，使得每个panel对应一个发送波束(一个波束对应一个TCI状态取值)。(1)一种实现方式是配置TCI状态与SRS resource set的对应关系(对应于上述第一对应关系；SRS resource set与面板之间存在对应关系，终端会确定此关系，具体可以为默认的)。所述TCI状态与SRS resource set的对应关系的配置方式与举例3类似，此处不再赘述。具体的，假设终端使用panel0传输SRS resource set0，且使用panel1传输SRS resource set1。当基站指示两个TCI状态且调度PUSCH传输时，终端根据所述映射关系(即对应关系)，传输SRS resource set 0的panel使用与SRS resource set0对应的TCI状态进行上行传输，传输SRS resource set 1的panel使用与SRS resource set1对应的TCI状态进行 上行传输。
(2)另一种实现方式是配置TCI状态(取值指示)与参数Panel的最大天线端口数索引的对应关系(对应于上述第一对应关系)。其中panel的最大天线端口数索引对应了不同的panel。1)一种配置方式可以是在波束指示的DCI信令中指示此对应关系。例如在DCI中增加对应关系域，同时系统预定义关系域取值(对应于码点Codepoint)与其对应关系，如下表11：
表11
2)另一种实现方式是使用MAC-CE信令指示所述关联关系。例如，在激活TCI状态(取值)的MAC-CE信令中，增加每个TCI状态位关联的Panel的最大天线端口数索引。具体与举例1类似(类似于在激活TCI状态的MAC-CE信令中，增加每个TCI状态位关联的CORESET；最大天线端口数索引对应CORESET)，在此不再赘述。
(3)另一种实现方式可以是通过RRC信令配置TCI状态(取值指示)与panel的最大天线端口数索引的对应关系。
举例7：
上述举例1-6中基站为终端指示了2个TCI状态(对应于向终端发送上述第一指示信令，TCI状态对应于上述TCI状态取值)，这种情况对应的是每个TRP与终端使用一个波束的场景；还可以是基站为终端指示了3个TCI状态(表示为TCI_state0，TCI_state1,TCI_state2)。其中TRP0与终端之间使用一个波束，即上下行波束相同；TRP1与终端之间使用两个波束，上行与下行使用不同的波束。在这种情况下，举例1-6中所述的第一个TCI状态与资源 或资源组(如CORESETPoolIndex等)的对应关系(包含于上述第一对应关系)可对应为第一个TCI状态信息与资源或资源组的对应。其中第一个TCI状态信息包括第一个TCI状态指示(如指示TCI_state0)。所述的第二个TCI状态与资源或资源组的对应关系(包含于上述第一对应关系)可对应为第二个TCI状态信息与资源或资源组的对应关系。其中第二个TCI状态信息包括第二个TCI状态指示和第三个TCI状态指示(如指示TCI_state1和TCI_state2)。类似的，基站还可以为终端指示4个TCI状态。其中TRP0与终端之间的上行和下行使用不同的波束，TRP1与终端之间的上行和下行使用不同的波束。在这种情况下，上述第一个TCI状态信息包括第一个TCI状态指示和第二个TCI状态指示；第二个TCI状态信息包括第三个TCI状态指示和第四个TCI状态指示。因此与TCI状态取值不同，每个TCI状态信息可以包括1个或多个TCI状态取值指示用于指示至少1个TCI状态取值。
举例8：
系统预定义下行PDCCH资源与上行的PUCCH资源或者PUSCH资源的关于TCI使用的对应关系(对应于上述第一对应关系)。例如，(1)系统预定义PDCCH资源与其调度的PUCCH资源使用相同的TCI状态(取值指示)关联关系。即若PDCCH资源所在的CORESET配置了使用了指示的第一个下行TCI状态(取值)，则此PDCCH资源所调度的PUCCH资源则使用指示的第一个上行TCI状态。如基站指示了两个下行TCI状态(取值)和两个上行TCI状态，分别表示为DL(下行)-TCI-State9和DL-TCI-State23，UL(上行)-TCI-State5和UL-TCI-State17。若CORESET#1配置了其使用第一个下行TCI状态(取值)，则CORESET#1使用DL-TCI-State9进行传输。根据所述预定义规则，PUCCH不需要再配置与TCI状态(取值)的对应关系：此时CORESET#1中承载的PDCCH所调度的PUCCH也遵循CORESET#1的TCI使用，其使用第一个上行TCI状态(取值)，即使用UL-TCI-State5进行传输。若基站指示了两个TCI状态(取值)，其为联合TCI，不区分上下行，则PDCCH资源与其调度的PUCCH资源使用相同的TCI状态(取值指示)。如，基站指示了TCI-State5和TCI-State7，且配置了CORESET#1使用第一个TCI状态(取值)，即TCI-State5；则CORESET#1中承载的PDCCH所调度的PUCCH也 使用第一个TCI状态，即TCI-State5进行传输。类似的，PUSCH传输也可以类似确定其TCI状态(取值)，不再赘述。
(2)另一种实现方式中，若基站指示了多个TCI状态(取值)，例如两个下行TCI状态(取值)和两个上行TCI状态，系统将预定义多个TCI状态(取值)的关联关系。例如，1)系统预定义第一个下行TCI状态(取值)和第一个上行TCI状态组合使用，第二个下行TCI状态和第二个上行TCI状态组合使用。这种情况下，对于PDCCH，当配置其使用第一个下行TCI状态(取值)时，其调度的PUCCH或PUSCH将根据与此第一个下行TCI状态关联的第一个上行TCI状态(取值)进行传输。如基站指示了两个下行TCI状态和两个上行TCI状态，分别表示为DL-TCI-State9和DL-TCI-State23，UL-TCI-State5和UL-TCI-State17。2)系统预定义第一个下行TCI状态(取值)和第一个上行TCI状态(取值)组合使用，第二个下行TCI状态(取值)和第二个上行TCI状态(取值)组合使用，即DL-TCI-State9和UL-TCI-State5关联，DL-TCI-State23和UL-TCI-State17关联。此时，若CORESET#1使用DL-TCI-State9传输，则其承载的PDCCH所调度的PUCCH使用UL-TCI-State5进行传输。
举例9：
本举例案中，针对“根据第二预定义信息，确定至少一个资源或资源组对应的波束方向；根据所述波束方向，进行所确定的资源或资源组的上行传输和/或下行传输；所述第二预定义信息，包括：终端进行小区接入时确定的同步信号块SSB的波束方向、物理上行共享信道PUSCH的波束方向，或预定义的TCI状态取值中的至少一项”进行具体举例，如下：
在基于M-DCI的Multi-TRP(多传输点)的传输方式中，基站(对应于上述网络设备)为终端配置CORESET Pool Index(控制资源集池索引)参数。其中CORESET Pool Index0对应一个TRP(传输点)，CORESET Pool Index1对应另一个TRP。一个MAC-CE信令为CORESET Pool Index0激活一组TCI状态，且使用DCI指示其中的一个TCI状态；另一个MAC-CE信令为CORESET Pool Index1激活一组TCI状态，且使用另一DCI指示其中的一个TCI状态。当基站通过RRC配置了TCI状态后，且在DCI进行TCI状态指 示前，由于没有TCI状态的指示，需要确定UE和TRP之间的默认波束，用于上下行传输。可以采用以下方式中的一种：
方式一：采用单TRP传输。对于小区间的多TRP传输场景，只有服务小区TRP进行传输。此时，下行传输使用服务小区接入过程中的SSB的波束方向作为默认波束方向进行传输；上行传输使用服务小区接入时，调度的PUSCH传输使用的波束方向进行传输。
对于小区内的多TRP传输场景，可以默认配置为仅使用一个CORESET Pool Index取值对应的TRP进行传输；例如，使用仅有CORESET Pool Index0的TRP进行传输。其中CORESET Pool Index0对应的下行传输使用服务小区接入过程中的SSB的波束方向作为默认波束方向进行传输；CORESET Pool Index0对应的上行传输使用(服务小区接入时，调度的PUSCH传输使用的波束方向)进行传输。
方式二：采用多TRP传输。对于小区间的多TRP传输场景，对于服务小区，下行传输使用服务小区接入过程中的SSB的波束方向作为默认波束方向进行传输；上行传输使用服务小区接入时，调度的PUSCH传输使用的波束方向进行传输。非服务小区的TRP可采用预定义的TCI状态。一种方式是采用RRC配置的TCI状态池中ID(标识)最小的TCI状态，或者采用MAC-CE激活信令中，最低码点对应的TCI状态。
对于小区内的多TRP传输场景,系统可预定义两个CORESET Pool Index取值对应的TRP的传输。例如，CORESET Pool Index0对应的TRP采用服务小区接入过程中的SSB的波束方向作为默认波束方向进行下行传输；采用服务小区接入时，调度的PUSCH传输使用的波束方向进行上行传输。对于CORESET Pool Index1对应的TRP采用预定义的TCI状态：一种方式是采用RRC配置的TCI状态池中ID最小的TCI状态，或者采用MAC-CE激活信令中，最低码点对应的TCI状态。
方式三：采用多TRP传输，且系统预定义默认的TCI状态对，所述TCI状态对保证终端可以同时接收到两个TRP的传输。一种预定义的方式可以是：采用RRC配置的TCI状态池中ID最小的两个TCI状态；或者采用MAC-CE信令激活的TCI状态中ID最小的两个TCI状态；或者采用MAC-CE激活信 令中，最低一个或两个码点对应的TCI状态。
举例10：
对于PDSCH(物理下行共享信道)和PUSCH以及免调度Type(类型)2CG(已配置授权)PUSCH的传输，均需要DCI进行调度指示。所述DCI通过在CORESET上传输的PDCCH(物理下行控制信道)承载。所述CORESET可以配置为使用举例1-8任一个中所述的基站指示的TCI状态，也可以配置为不使用举例1-8中所述的基站指示的TCI状态。当所述CORESET被配置为使用举例1-8任一个中所述的基站指示的TCI状态时，PDSCH、PUSCH和/或Type 2CG PUSCH可以调度其(本身，即PDSCH、PUSCH和/或Type 2CG PUSCH)传输的PDCCH所在的CORESET相同的TCI状态进行传输。例如，CORESET1中传输的DCI format 0_1和/或0_2调度了PUSCH的传输，且CORESET1被配置为使用举例1-8任一个中指示的两个TCI状态中的一个；则所述PUSCH也将使用此TCI状态进行上行传输。
当所述CORESET被配置为不使用举例1-8中所述的基站指示的TCI状态时，PDSCH、PUSCH和/或Type 2CG PUSCH不再使用此CORESET相同的TCI状态进行传输。此时，可以使用(调度PDCCH所在的CORESET所对应的)CORESET Pool Index相对应的TCI状态。例如，所述CORESET对应CORESET Pool Index0，且基站通过MAC-CE或DCI指示CORESET Pool Index0对应的TCI状态；则PDSCH、PUSCH和/或Type2CG PUSCH均使用指示的该TCI状态。
另一种方式是，PDSCH、PUSCH和/或Type 2CG PUSCH均使用所述调度的PDCCH中指示的TCI状态。例如，所述CORESET中的PDCCH format(格式)1_1和/或1_2指示了一个TCI状态；则由此CORESET中传输的PDCCH所调度的PDSCH、PUSCH和/或Type2CG PUSCH均使用所述PDCCH format 1_1和/或1_2指示的TCI状态。
在此说明，本公开中的(服务)小区接入，是指终端进行的(服务)小区接入，但并不以此为限。

需要说明的是，应理解以上各个模块的划分仅仅是一种逻辑功能的划分，实际实现时可以全部或部分集成到一个物理实体上，也可以物理上分开。且这些模块可以全部以软件通过处理元件调用的形式实现；也可以全部以硬件的形式实现；还可以部分模块通过处理元件调用软件的形式实现，部分模块通过硬件的形式实现。例如，某个模块可以为单独设立的处理元件，也可以集成在上述装置的某一个芯片中实现，此外，也可以以程序代码的形式存储于上述装置的存储器中，由上述装置的某一个处理元件调用并执行以上确定模块的功能。其它模块的实现与之类似。此外这些模块全部或部分可以集成在一起，也可以独立实现。这里所述的处理元件可以是一种集成电路，具有信号的处理能力。在实现过程中，上述方法的各步骤或以上各个模块可以通过处理器元件中的硬件的集成逻辑电路或者软件形式的指令完成。
例如，各个模块、单元、子单元或子模块可以是被配置成实施以上方法的一个或多个集成电路，例如：一个或多个特定集成电路(Application Specific Integrated Circuit，ASIC)，或，一个或多个微处理器(digital signal processor，DSP)，或，一个或者多个现场可编程门阵列(Field Programmable Gate Array，FPGA)等。再如，当以上某个模块通过处理元件调度程序代码的形式实现时，该处理元件可以是通用处理器，例如中央处理器(Central Processing Unit，CPU)或其它可以调用程序代码的处理器。再如，这些模块可以集成在一起，以片上系统(System-On-a-Chip，SOC)的形式实现。
本公开的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开的实施例，例如除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B和/或C，表示包含单独A，单独B， 单独C，以及A和B都存在，B和C都存在，A和C都存在，以及A、B和C都存在的7种情况。类似地，本说明书以及权利要求中使用“A和B中的至少一个”应理解为“单独A，单独B，或A和B都存在”。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
