技术领域
本公开涉及通信技术领域，尤其涉及一种波束指示方法、装置、终端及网络侧设备。
背景技术
在新空口(New Radio，NR)系统中，下行信道包括物理下行共享信道(Physical Downlink Shared Channel，PDSCH)，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)，以及物理上行控制信道(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参考信号(Channel State Information Reference Signal，CSI-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。
在确定了不同信道的波束方向后，需要使用信令指示信道传输时的波束，即波束指示。对于PUCCH信道，基站通过高层信令SpatialRelationInfo半静态的配置给终端多个波束方向，并通过媒体接入控制层控制单元(Medium Access Control-Control Element，MAC-CE)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下行控制信息(Downlink Control  Information，DCI)中SRS资源指示(SRS Resource Indicator，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(Control Resource Set，CORESET)配置多个传输配置指示状态(Transmission Configuration Indicator state，TCI 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。
在相关技术的方案中，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使用相同的波束方向传输；上行控制信道PUCCH和上行共享信道PUSCH也会使用相同的波束方向。另外，当波束互易性存在时，上行信道和下行信道也可能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。

基站可在基站控制器的控制下与终端11通信，在各种示例中，基站控制器可以是核心网或某些基站的一部分。一些基站可通过回程与核心网进行控制信息或用户数据的通信。在一些示例中，这些基站中的一些可以通过回程链路直接或间接地彼此通信，回程链路可以是有线或无线通信链路。无线通信系统可支持多个载波(不同频率的波形信号)上的操作。多载波发射机能同时在这多个载波上传送经调制信号。例如，每条通信链路可以是根据各种无线电技术来调制的多载波信号。每个已调信号可在不同的载波上发送并且可携带控制信息(例如，参考信号、控制信道等)、开销信息、数据等。
基站可经由一个或多个接入点天线与终端11进行无线通信。每个基站可以为各自相应的覆盖区域提供通信覆盖。接入点的覆盖区域可被划分成仅构成该覆盖区域的一部分的扇区。无线通信系统可包括不同类型的基站(例如宏基站、微基站、或微微基站)。基站也可利用不同的无线电技术，诸如蜂窝或WLAN无线电接入技术。基站可以与相同或不同的接入网或运营商部署相关联。不同基站的覆盖区域(包括相同或不同类型的基站的覆盖区域、利用相同或不同无线电技术的覆盖区域、或属于相同或不同接入网的覆盖区域)可以交叠。
无线通信系统中的通信链路可包括用于承载上行链路(Uplink，UL)传输(例如，从终端11到网络设备12)的上行链路，或用于承载下行链路 (Downlink，DL)传输(例如，从网络设备12到终端11)的下行链路。UL传输还可被称为反向链路传输，而DL传输还可被称为前向链路传输。下行链路传输可以使用授权频段、非授权频段或这两者来进行。类似地，上行链路传输可以使用有授权频段、非授权频段或这两者来进行。
本公开实施例提供了一种波束指示方法，如图2所示，该方法在应用于第一终端侧时，包括：
步骤21，第一终端接收第一消息，所述第一消息包括用于指示N个波束方向的波束相关信息，所述N为大于或等于1整数。
这里，本公开实施例在第一消息中携带波束相关信息，波束相关信息用于指示N(大于或等于1)个的波束方向。具体的，所述波束相关信息中的波束方向可以通过传输配置指示TCI状态、准共址(Quasi co-location，QCL)参数、空间关系信息(SpatialRelationInfo)、上行参考信号的索引、下行参考信号的索引、同步信号的索引、上行信道和下行信道中的一种或多种进行指示。其中，在采用所述上行参考信号的索引、下行参考信号的索引、同步信号的索引、上行信道或下行信道指示波束方向时，所指示的波束方向为：所述上行参考信号、下行参考信号、同步信号、上行信道或下行信道最近一次使用的波束方向。
本公开实施例可以预先定义或预先配置多种信道信号组合，具体的，所述信道信号组合可以是网络侧和终端侧预先定义的，或者是由网络侧设备确定并指示给终端的，或者是由终端确定并反馈给网络侧设备的。每种所述信道信号组合包括至少两个信道和/或参考信号，这里所述信道可以包括PDSCH、PDCCH、PUSCH和PUCCH中的一种或多种，所述参考信号可以包括CSI-RS和SRS中的一种或多种。具体的，所述信道信号组合可以包括以下组合中的至少一种：
1)上行信道和/或上行参考信号；
2)下行信道和/或下行参考信号；
3)上行信道和下行信道；
4)上行信道和下行参考信号；
5)上行参考信号和下行信道；
6)上行参考信号和下行参考信号。
所述第一消息中的波束相关信息可以是N种信道信号组合中的每种信道信号组合的波束方向，这样，第一消息可以指示至少两个信道和/或参考信号的波束方向。这里，至少两个信道和/或参考信号是PDCCH、PDSCH、PUCCH、PUSCH、CSI-RS和SRS中的至少两个。例如，所述至少两个信道和/或参考信号可以是PDCCH和PDSCH；或者，所述至少两个信道和/或参考信号PDCCH、PDSCH和CSI-RS；或者，所述至少两个信道和/或参考信号是PUCCH和PUSCH；或者，所述至少两个信道和/或参考信号是PUCCH、PUSCH和SRS；或者，所述至少两个信道和/或参考信号是PDCCH和PUCCH，等等，此处不再一一举例。
所述第一消息中的波束相关信息还可以是M个终端的波束方向，所述M为大于或等于2，且小于或等于N的整数。这里，波束相关信息中指示的每个终端的波束方向可以是至少1个，针对M个终端一共指示了N个波束方向。

步骤22，所述第一终端根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输。
这里，本公开实施例在步骤22中利用所述波束相关信息指示的波束方向，进行至少两个目标信道和/或目标参考信号的传输。类似的，所述至少两个目标信道和/或目标参考信号是PDCCH、PDSCH、PUCCH、PUSCH、CSI-RS和SRS中的至少两个。
需要说明的是，本公开实施例所述的传输包括发送和/或接收。例如，当所述波束相关信息指示的波束为发送波束时，在发送所述目标信道和/或目标 参考信号时，可以使用所述发送波束进行发送；在接收所述目标信道和/或目标参考信号时，可以在所述发送波束的方向上接收所述目标信道和/或目标参考信号。类似的，当所述波束相关信息指示的波束为接收波束时，在发送所述目标信道和/或目标参考信号时，可以使用所述接收波束的方向上进行发送；在接收所述目标信道和/或目标参考信号时，可以使用所述接收波束进行接收。
通过以上步骤，本公开实施例可以利用一个第一消息指示的波束方向，进行至少两个目标信道和/或目标参考信号的传输，从而通过一个信令消息指示多个信道/参考信号的赋形波束，可以降低波束指示的复杂度和指示信令的开销。另外，本公开实施例还可以在需要改变波束时，发送上述第一消息，从而可以实现动态的波束指示，增加了上下行波束控制的灵活性。
在本公开的某些实施例中，在所述第一消息通过用户设备组公共下行控制信息UE group common DCI、DCI format 0-1、DCI format 0-2、DCI format 1-0、DCI format 1-1和专用的物理层动态信令中的一个进行指示时，所述第一终端还可以在第一上行资源上反馈所述第一消息的接收确认信息，或者，使用第一上行资源指示所述第一消息的接收确认信息。这里，所述第一上行资源是根据预定义的所述第一消息与第一上行资源之间的对应关系确定的，或者是根据所述第一消息中包括的上行资源分配指示域确定的。所述接收确认信息用于指示所述第一终端是否收到所述第一消息。
在第一上行资源上反馈所述第一消息的接收确认信息，具体可以在第一上行资源上发送ACK/NACK信息，ACK/NACK用于指示收到/未收到第一消息。使用第一上行资源指示所述第一消息的接收确认信息，具体可以是通过发送所述第一上行资源来指示第一终端收到所述第一消息。
在本公开的某些实施例中，所述N等于1。此时，在步骤22中，根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输，具体可以包括：将所述波束相关信息指示的唯一一个波束方向，确定为第一波束方向；根据预配置信息或根据网络侧发送的用于指示信道信号组合的组合指示信息，确定出所述至少两个目标信道和/或目标参考信号；基于所述第一波束方向，与网络侧之间进行所述至少两个目标信道和/或目标参考信号的传输。这里预配置信息可以是网络侧和终端侧预定义的，或者是预先由网络侧配置 给终端的。所述组合指示信息可以通过所述第一消息发送，此时所述第一消息还包括用于指示所述信道信号组合的组合指示信息。当然，本公开实施例也可以通过其他的消息发送所述组合指示信息。
在本公开的某些实施例中，所述N大于1。此时，在步骤22中，根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输，具体可以包括：
a)在所述N个波束方向为N种信道信号组合中的每种信道信号组合的波束方向时，按照所述N个波束方向与信道信号组合的第一对应关系，确定各个信道信号组合的第一波束方向；基于所确定的各个信道信号组合的第一波束方向，与网络侧之间进行对应信道信号组合中的信道和/或信号的传输。这里，所述第一对应关系可以是网络侧和终端侧预定义的，或者是预先由网络侧配置给终端的。
b)在所述N个波束方向为M个终端的波束方向时，按照所述N个波束方向与终端的第二对应关系，确定所述第一终端的第一波束方向；根据预配置信息或根据网络侧发送的用于指示信道信号组合的组合指示信息，确定出所述至少两个目标信道和/或目标参考信号；基于所述第一波束方向，与网络侧之间进行所述至少两个目标信道和/或目标参考信号的传输。这里，所述第二对应关系可以是网络侧和终端侧预定义的，或者是预先由网络侧配置给终端的。
另外，所述第一波束方向可以是至少一个波束方向。在所述第一波束方向大于或等于2个时，还可以根据波束方向与信道信号组合之间的第三对应关系，确定所述第一波束方向中的各个信道信号组合对应的波束方向，从而利用各个信道信号组合对应的波束方向进行相关信道和/或信号的传输。
为了增加波束控制的灵活性，本公开实施例还可以通过在所述第一消息包括用于指示所述信道信号组合是否使用所述波束相关信息中的波束方向的波束有效指示信息，或者包括用于指示使用所述波束相关信息中的波束方向的波束的有效时间的波束有效时间指示信息。
例如，在所述第一消息包括所述波束有效指示信息时，本公开实施例仅在波束有效指示信息为有效时，所述信道信号组合使用所述波束相关信息中 的波束方向，此时将执行上述步骤22中的根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输的步骤；而在波束有效指示信息为无效时，所述信道信号组合不使用所述波束相关信息中的波束方向，此时可以使用相关技术的独立波束指示的方案，对此本文不再赘述。
又例如，在所述第一消息包括所述波束有效时间指示信息时，本公开实施例仅在当前时间属于所述有效时间时，所述信道信号组合使用所述波束相关信息中的波束方向，此时将执行上述步骤22中的根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输的步骤；而在当前时间不属于所述有效时间时，所述信道信号组合不使用所述波束相关信息中的波束方向，此时可以使用相关技术的独立波束指示的方案，对此本文不再赘述。
可选的，本公开实施例的所述信道信号组合使用所述波束相关信息中的波束方向的有效时间还可以是预定义(如终端和网络侧预先约定的)的或者由网络侧设备进行配置。
作为另一种实现方式，本公开实施例还可以通过所述第一消息之外的其他消息发送所述组合指示信息和/或波束有效指示信息。例如，网络侧设备还可以通过第二消息发送所述组合指示信息，和/或，通过第三消息发送所述波束有效指示信息。此时，所述第一终端接收第二消息，所述第二消息包括用于指示所述信道信号组合的组合指示信息，从而可以获得组合指示信息；和/或，接收第三消息，所述第三消息包括用于指示所述信道信号组合是否使用所述波束相关信息中的波束方向的波束有效指示信息，从而可以获得所述波束有效指示信息。又例如，网络侧设备还可以通过第四消息同时发送所述组合指示信息和波束有效指示信息，等等。此时，终端接收所述第四消息，可以获得组合指示信息和波束有效指示信息。另外，作为又一种实现方式中，所述第三消息可以包括所述波束有效指示信息或者包括用于指示使用所述波束相关信息中的波束方向的波束的有效时间的时间指示信息。类似的，所述终端仅在所述波束有效指示信息为有效或当前时间属于所述有效时间时，执行根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输的步骤。
类似的，所述第一消息、第二消息、第三消息和第四消息可以通过RRC 信令、MAC-CE信令、UE group common DCI、DCI format 0-1、DCI format 0-2、DCI format 1-0、DCI format 1-1中的一个进行指示。其中，在通过DCI format 0-1、DCI format 0-2、DCI format 1-0或DCI format 1-1指示所述消息时，所述DCI format 0-1、DCI format 0-2、DCI format 1-0或DCI format 1-1中的预设字段的取值为预设值，所述预设值表示本DCI format用于指示所述消息。

2)根据预定义的时间范围，确定所述有效时间。
这里，所述预定义的时间范围，又可以包括至少以下一种方式：
A)所述预定义的时间范围为进行所述至少两个目标信道和/或目标参考信号的一次传输的时间，所述波束相关信息仅在进行所述至少两个目标信道和/或目标参考信号的一次传输的时间内有效；
B)所述预定义的时间范围为系统预定义的有效时间的持续时间长度。例如，预定义的时间范围可以是预先存在终端本地的，例如，在终端出厂时即写入终端的内存中。
3)根据网络侧的配置，确定所述有效时间。
其中，仅在所述波束相关信息生效时或当前时间属于所述有效时间时，执行上述步骤22中的根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输。
更进一步的，所述终端还可以根据网络侧(如基站)的配置，获得所述有效时间的确定方式，例如，从上述3种方式中选择出某一种。作为一种实现方式，所述有效时间的确定方式可以由所述第一消息进行指示，即在所述第一消息中配置所述有效时间的确定方式。
以上从终端侧介绍了本公开的波束指示方法的至少一种实现方式，下面请参照图3，本公开实施例提供的波束指示方法，在应用于网络侧设备，如基站时，包括：
步骤31，生成第一消息，所述第一消息包括用于指示N个波束方向的波束相关信息，所述N为大于或等于1的整数。

5)上行参考信号和下行信道；
6)上行参考信号和下行参考信号。

通过以上步骤，本公开实施例可以由网络侧向终端发送第一消息，从而通过一个信令消息指示多个信道/参考信号的赋形波束，可以降低波束指示的复杂度和指示信令的开销。另外，本公开实施例还可以在需要改变波束时，发送上述第一消息，从而可以实现动态的波束指示，增加了上下行波束控制的灵活性。
在上述步骤32之后，网络侧设备还可以根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输。类似的，所述至少两个目标信道和/或目标参考信号是PDCCH、PDSCH、PUCCH、PUSCH、CSI-RS和SRS中的至少两个。

又例如，在所述第一消息包括所述波束有效时间指示信息时，本公开实施例仅在当前时间属于所述有效时间时，所述信道信号组合使用所述波束相关信息中的波束方向，此时网络侧根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输的步骤；而在当前时间不属于所述有效时间时，所述信道信号组合不使用所述波束相关信息中的波束方向，此时可以使用相关技术的独立波束指示的方案，对此本文不再赘述。

作为另一种实现方式，本公开实施例还可以通过所述第一消息之外的其他消息发送所述组合指示信息和/或波束有效指示信息。例如，网络侧设备还可以通过第二消息发送所述组合指示信息，和/或，通过第三消息发送所述波束有效指示信息。又例如，网络侧设备还可以通过第四消息同时发送所述组合指示信息和波束有效指示信息，等等。
另外，作为又一种实现方式中，所述第三消息可以包括所述波束有效指示信息或者包括用于指示使用所述波束相关信息中的波束方向的波束的有效时间的时间指示信息。类似的，所述终端仅在所述波束有效指示信息为有效或当前时间属于所述有效时间时，执行根据所述波束相关信息，进行至少两个目标信道和/或目标参考信号的传输的步骤。

以下对本公开实施例的波束指示方法在终端和网络侧的实现均进行了说明。下面结合附图进一步提供应用本公开实施例波束指示方法的若干示例。以下各示例中，波束相关信息域是用于携带波束相关信息的域；波束有效指示信息域是用于携带波束有效指示信息的域；信道信号组合指示域是用于携带组合指示信息的域；第一信令即为本公开实施例所述的第一消息。
示例1：
基站确定第一信令，格式如表1所示。其包括波束相关信息域，其中包含N＝1个波束方向信息；还包括信道组合的波束有效指示信息域。这里的波束可以由TCI状态指示也可以由QCL参数或SpatialRelationInfo参数指示。以下均简称为波束。
波束相关信息域 波束有效指示信息域
表1
系统预定义信道和或参考信号组合为全部上下行信道，即此N＝1个波束方向用于PDCCH/PDSCH/PUCCH/PUSCH。假设系统为终端配置了S＝128个TCI状态，表示为TCI0,TCI1,…,TCI127,每个状态对应一个波束方向。通过基站的波束扫描，确定了TCI6作为全部信道的波束方向。则通过表2的第一信令(即本文的第一消息)指示给终端。
TCI6 ON
表2
终端接收到此第一信令后，根据波束有效指示信息域为‘ON’的状态，确定后续的PDCCH信道，PDSCH信道，PUCCH信道和PUSCH信道均使用TCI6所指示的波束进行传输。
若后续终端接收到表3所示的第一信令(即本文的第一消息)，根据波束有效指示信息域为‘OFF’的状态，其表示信道组合的波束失效。则PDCCH信道，PDSCH信道，PUCCH信道和PUSCH信道分别使用其各自的波束指示信令所指示的波束传输。即采用相关技术的NR系统波束指示方式。或者，OFF状态后，所有的信道使用其各自的默认波束进行传输。此后的四个信道不再使用相同的波束进行传输。
TCI6 OFF
表3
所述的第一信令可以使用UE group common的DCI进行传输。可以在在目前的DCI中增加一个DCI format 2-7进行传输。也可以使用UE specific的DCI进行传输，如以DCI format 1-1为例，一种可能的方式是将其中‘Transmission configuration indication(传输配置指示)’域作为波束相关信息域，用于指示TCI6。而将‘Time domain resource assignment(时域资源分配)’域作为波束有效指示信息域，取值全0表示OFF，全1表示ON。且系统预定义DCI format 1-1的其余信息域取值为全1时，表示此DCI为所述第一信令，否则为正常模式的DCI format 1-1。
示例2：
基站确定第一信令，格式如表4所示。其包括波束相关信息域，其中包含N＝1个波束方向信息；还包括信道组合的波束有效指示信息域。同时包括信道组合的指示域。
波束有效指示信息域 信道信号组合指示域 波束相关信息域
表4
系统预定义信道和或参考信号组合包含以下三种组合：
全部上下行信道，全部上行信道，全部下行信道
信道组合的指示域使用2比特指示其中的一种组合。例如使用‘00’指示全部上下行信道；使用‘01’指示全部上行信道；使用‘10’指示全部下行信道。假设系统为终端配置S＝128个TCI状态，表示为TCI0,TCI1,…,TCI127,每个状态对应一个波束方向。通过基站的波束扫描，确定了TCI6作为上行信道的波束方向。则通过表5的信令指示给终端。
ON 01 TCI6
表5
终端接收到此第一信令后，根据波束有效指示信息域为‘ON’的状态，确定后续的PUCCH信道和PUSCH信道均使用TCI6所指示的波束进行传输。
示例3：
基站确定第一信令，格式如表6所示。其包括波束相关信息域，其中包含N＝2个波束方向信息；还包括N＝2个信道组合的波束有效指示信息域。
Figure PCTCN2021104009-appb-000001
表6
系统预定义信道和或参考信号组合包含两种组合：全部上行信道和全部下行信道。其中全部上行信道对应信息域-0，全部下行信道对应信息域-1。
假设系统为终端配置S＝128个TCI状态，表示为TCI0,TCI1,…,TCI127,每个状态对应一个波束方向。通过基站的波束扫描，确定了TCI6作为上行信道的波束方向，且确定TCI18作为下行信道的波束方向。则通过表7的信令指示给终端。
ON ON TCI6 TCI18
表7
终端接收到此第一信令后，根据波束有效指示信息域为‘ON’的状态，确定后续的PUCCH信道和PUSCH信道均使用TCI6所指示的波束进行传输， 后续的PDCCH和PDSCH信道均使用TCI18所指示的波束进行传输。
若以上的两个波束相关信息域配置为相同的TCI，则表示全部的上下行信道使用相同的波束进行传输。
示例4：
基站确定第一信令，格式如表8所示。包括波束相关信息域，其中包含N＝3个波束方向信息；还包括信道组合的波束有效指示信息域。
Figure PCTCN2021104009-appb-000002
表8
上述N＝3个波束方向信息分别对应三个终端。系统预定义信道和或参考信号组合为全部上下行信道。
假设系统为三个终端分别配置了128,64,128个TCI状态,每个状态对应一个波束方向。通过基站的波束扫描，确定了128个TCI状态中的TCI6作为终端0的信道组合的波束方向，64个TCI状态中的TCI60作为终端1的信道组合的波束方向以及128个TCI状态中的TCI78作为终端2的信道组合的波束方向。则通过表9的信令指示给终端。
ON TCI6 TCI60 TCI78
表9
所述的第一信令可以使用UE group common DCI进行传输。可以在目前的DCI中增加一个DCI format 2-7进行传输。每个终端接收到此第一信令后，确定与其对应的波束相关信息域，再根据波束有效指示信息域为’ON’的状态，确定全部信道的传输波束方向。例如终端2确定后续的PDCCH/PDSCH、PUCCH/PUSCH信道均使用TCI78所指示的波束进行传输。
示例5：
基站确定第一信令，格式如表10所示。其包括波束相关信息域，其中包含N＝1个波束方向信息；还包括信道组合的波束有效指示信息域。
波束相关信息域 波束有效指示信息域
表10
系统预定义信道和或参考信号组合为全部上下行信道和用于CSI获取的上下行参考信号，即此N＝1个波束方向用于PDCCH/PDSCH/PUCCH/PUSCH/CSI-RS for CSI acquisition(用于CSI获取的信道状态信息参考信号)/SRS for codebook or noncodebook(基于码本或非码本的SRS)。系统预定义所述波束方向信息可以配置为上行信道或者下行信道，即可以配置为‘PDCCH’，‘PDSCH’，‘PUCCH’和‘PUSCH’。其表示波束方向与波束相关信息域中指示的信道的最近一次的波束方向相同。则通过表11的信令指示给终端。
PDCCH ON
表11
终端接收到此第一信令后，根据波束有效指示信息域为‘ON’的状态，确定后续的PDCCH信道，PDSCH信道，PUCCH信道，PUSCH信道，CSI-RS for CSI acquisition，SRS for codebook以及SRS for noncodebook均使用最近一次的PDCCH传输所使用的波束。
示例6：
基站确定第一信令，格式如表12所示。包括波束相关信息域，其中包含N＝1个波束方向信息；还包括信道信号组合指示域。所述信道信号组合指示域采用4个比特，每个比特分别对应一个信道。如表12所示，其中，PDCCH、PDSCH、PUCCH和PUSCH分别信道信号组合指示域中的各个比特所对应的信道。
波束相关信息域 PDCCH PDSCH PUCCH PUSCH
表12
假设系统确定应用相同波束的信道组合为PDCCH和PDSCH，则将其对应的信息域分别设置为1。假设系统为终端分别配置了128个TCI状态,每个状态对应一个波束方向。通过基站的波束扫描，确定了128个TCI状态中的 TCI9作为信道组合的波束方向，则通过表13的信令指示给终端。
TCI9 1 1 0 0
表13
终端接收到此第一信令后，确定后续的PDCCH信道和PDSCH信道使用TCI9对应的波束进行传输。
进一步的，此第一信令中没有波束有效指示信息域。可以通过不同的RNTI对此信令进行加扰来区分波束有效还是波束失效。例如使用RNTI1加扰的第一信令表示波束有效，使用RNTI2加扰的第一信令表示波束失效。此方法也可以应用于其他实施例中。或者，
系统预定义波束有效时间为从接收到此第一信令开始至下一次接收到此第一信令为止。在此时间范围内使用TCI9对应的波束，而下一次接收到第一信令后，更换为所述第一信令中指示的波束。此方法也可以应用于其他实施例中。或者，
系统预定义波束有效时间为从接收到此第一信令开始后持续Q＝10个时隙。在此时间范围内使用TCI9对应的波束。此方法也可以应用于其他实施例中。或者，
系统预定义波束的有效时间为一次的信道传输。例如TCI9仅用于后续的一次的PDSCH和PDCCH的信道传输。完成一次的信道传输后，TCI9即失效。
进一步的，采用波束有效时间为从接收到此第一信令开始后持续Q＝10个时隙，还是采用波束的有效时间为一次的信道传输，可以由基站配置。例如，在第一信令中还包括波束有效时间域，其采用1比特。取值为‘1’时，指示波束有效时间为从接收到此第一信令开始后持续Q＝10个时隙，取值为‘0’时，指示波束的有效时间为一次的信道传输。也可以由高层信令指示采用哪一种方式来确定波束的有效时间。
基站通过物理层信令或者高层信令指示波束有效时间。例如，系统通过RRC信令配置波束有效时间为{10，20，100，1000}个时隙(slot)。所述第一信令中包含一个有效时间指示域，如表14所示。波束有效时间指示信息域使 用2比特分别指示上述10、20、100和1000个slot。
波束相关信息域 波束有效时间指示信息域
表14
如采用表15的指示，说明从此信令开始，有效时间为10个slot。使用TCI6对应的波束。
TCI6 00
表15
此方法也可以应用于其他实施例中。
示例7：
基站确定第一信令，其中至少包括表16所示的两个信息域。其中波束相关信息域包含N＝1个波束方向信息，用于指示一个公共波束方向；上行信道资源分配域指示上行的PUCCH资源信息或上行PUSCH资源信息或PRACH资源信息。
波束相关信息域 上行信道资源分配域
表16
终端收到此第一信令后，在所述PUCCH资源或PUSCH资源上反馈ACK/NACK信息，指示是否正确接收到所述波束方向信息，基站在所述PUCCH资源或PUSCH资源上接收终端上报的ACK/NACK信息。若上报的是ACK信息，则说明终端正确接收到所述第一信令。若上报的是NACK信息或者在所述PUCCH资源或所述PUSCH资源上未接收到终端的反馈，则所述第一信令未被终端正确接收。基站将重传所述第一信令。
或者，
终端收到此第一信令后，终端发送PRACH资源告知基站收到所述第一信令。基站接收所述PRACH资源。若在相应位置接收到所述PRACH资源，说明终端正确接收到所述第一信令；若未收到所述PRACH资源，则所述第一信令未被终端正确接收，此时，基站可以重传所述第一信令。
示例8：
基站确定第一信令，其中至少包括表17所示的1个信息域。其中波束相关信息域包含N＝1个波束方向信息，用于指示一个公共波束方向。
波束相关信息域
表17
系统预定义上行资源与所述第一信令的关系。例如，系统预定义在所述第一信令发送时刻最近的上行资源(如PUCCH资源)上反馈ACK/NACK信息；或者系统预定义在所述第一信令发送时刻最近的随机接入时机(RACH Occasion,RO)上发送PRACH。也可以预定义为在所述第一信令发送时刻的K个时隙偏移后的最近的上行资源上反馈ACK/NACK信息。或者系统预定义在所述第一信令发送时刻的K个时隙偏移后的最近的随机接入时机(RACH Occasion,RO)上发送PRACH。
终端收到此第一信令后，在所述PUCCH资源上反馈ACK/NACK信息，指示是否正确接收到所述波束方向信息。或者，终端发送PRACH资源告知基站收到所述第一信令。
基站根据所述预定义关系，在所述PUCCH资源上接收终端上报的ACK/NACK信息。若上报的是ACK信息，则说明终端正确接收到所述第一信令。若上报的是NACK信息或者在所述PUCCH资源上未接收到终端的反馈，则所述第一信令未被终端正确接收。基站将重传所述第一信令。或者，
基站接收所述PRACH资源。若在相应位置接收到所述PRACH资源，说明终端正确接收到所述第一信令。若为收到所述PRACH资源，则所述第一信令未被终端正确接收。基站将重传所述第一信令。
