一种资源配置方法及装置
相关申请的交叉引用
本申请要求在2022年08月17日提交中国专利局、申请号为202210984241.9、申请名称为“一种资源配置方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种资源配置方法及装置。
背景技术
在无线通信系统中，基站可向终端发送信道状态信息-参考信号(channel-state information reference signal，CSI-RS)，用于测量下行信道的质量。例如，终端可对接收的CSI-RS进行测量，确定测量结果，并将测量结果反馈给基站。基站可根据终端反馈的测量结果，调整后续下行数据的调度策略。在上述过程中，基站预先将CSI-RS资源配置给终端，终端在配置的资源上检测CSI-RS。关于基站如何向终端配置CSI-RS资源，是本申请实施例关注的问题。
发明内容
本申请实施例提供一种资源配置方法及装置，以使得基站向终端配置CSI-RS资源。
第一方面，提供一种资源配置方法，该方法的执行主体为终端，或者设置于终端中的部件(处理器、芯片或其它等)，以终端为执行主体为例，该方法包括：在终端接入第一小区的情况下，终端接收来自网络设备的无线资源控制RRC消息，所述RRC消息用于为所述终端配置N个信道状态信息-参考信号CSI-RS资源，N为正整数。例如，该RRC消息中包括为所述终端配置的CSI-RS资源集，所述CSI-RS资源集中包括N个CSI-RS资源；在所述终端在所述第一小区中的第一位置区域的情况下，终端接收来自所述网络设备的第一媒体接入控制MAC控制信元CE，所述第一MAC CE用于激活所述终端在同一个周期内，在所述N个CSI-RS资源中的M1个CSI-RS资源上测量CSI-RS，所述M1个CSI-RS资源中至少包括所述第一位置区域关联的CSI-RS资源，M1为小于或等于N的正整数；在同一个周期内，终端在所述M1个CSI-RS资源上测量来自所述网络设备的所述CSI-RS。
通过上述设计，在终端接入一小区的情况下，假设该小区称为第一小区，网络设备将第一小区关联的CSI-RS资源通过RRC消息配置给终端；在终端移动到第一小区的一个位置区域的情况下，假设该位置区域称为第一位置区域，可选的，位置区域可称为波束覆盖区域，则网络设备向终端发送MAC CE，激活第一位置区域关联的CSI-RS资源。终端在激活的CSI-RS资源上，周期性的测量CSI-RS。相对于目前方案中，基站通过RRC信令为终端配置CSI-RS资源，终端直接在配置的CSI-RS资源上测量CSI-RS。在目前的方案中，一个RRC信令最多配置8个CSI-RS资源，一个位置区域关联至少一个CSI-RS资源。在终端高速移动，或者，由于卫星移动导致终端所处于的位置区域频繁变化时，网络设备 需要频繁的为终端进行RRC重配。而在本申请的设计中，在终端接入某个小区的情况下，网络设备通过RRC信令将该小区关联的CSI-RS资源配置给终端；当终端移动到该小区中的某个位置区域时，再通过MAC CE信令激活该位置区域相关联的CSI-RS资源，终端在激活的CSI-RS资源上，测量CSI-RS。采用本申请的方案，当终端接入某个小区时，网络设备无需进行频繁的RRC重配，只需要MAC CE激活不同的位置区域关联的CSI-RS资源即可。而对于RRC配置的过程，空口开销通常有几十比特，MAC CE的空口开销通常为十几比特，因此，采用上述方案，可以节省CSI-RS资源配置的空口开销。
可选的，上述M1个CSI-RS资源中，除包括第一小区中的第一位置区域关联的CSI-RS资源外，还可以包括其它位置区域关联的CSI-RS资源，比如，第一位置区域相邻的多个位置区域的CSI-RS资源。如此，网络设备通过一个MAC CE可激活终端在多个位置区域关联的CSI-RS资源上测量CSI-RS，无需终端每移动到一个位置区域，则发送一次MAC CE激活对应的CSI-RS，从而进一步减少CSI-RS资源配置的空口开销。
在一种设计中，所述终端在同一个周期内，最多支持在X个CSI-RS资源上测量CSI-RS，X为小于或等于N的正整数。可选的，针对上述第一方面的应用场景为：终端支持CSI-RS测量的能力，小于一个小区关联的全部CSI-RS资源的场景。在这种情况下，终端的能力，无法支持终端同时在一个小区关联的全部CSI-RS资源进行CSI-RS测量。
在一种设计中，在所述终端由所述第一小区中的所述第一位置区域移动到所述第一小区中的第二位置区域的情况下，还包括：终端接收来自所述网络设备的第二MAC CE，所述第二MAC CE用于激活所述终端在同一个周期内，在所述N个CSI-RS资源中的M2个CSI-RS资源上测量所述CSI-RS，所述M2个CSI-RS资源中至少包括所述第二位置区域关联的CSI-RS资源，M2为小于或等于N的正整数。
通过上述设计，在终端移动到第一位置区域的情况下，网络设备向终端发送第一MAC CE，该第一MAC CE用于激活第一位置区域关联的CSI-RS资源，终端在第一位置区域关联的CSI-RS资源上测量CSI-RS；而在终端移动到第二位置区域的情况下，网络设备向终端发送第二MAC CE，该第二MAC CE用于激活第二位置区域关联的CSI-RS资源，终端在第二位置区域关联的CSI-RS资源上测量CSI-RS，从而实现根据终端的位置区域不同，通过MAC CE激活终端在相应的CSI-RS资源上测量CSI-RS。
在一种设计中，所述N个CSI-RS资源为所述第一小区关联的全部CSI-RS资源。可选的，第一小区包括至少一个位置区域，每个位置区域关联至少一个CSI-RS资源，第一小区关联的全部CSI-RS资源可指：第一小区中包括的全部位置区域关联的CSI-RS资源。可选的，位置区域还可称为波束等。
通过上述设计，在终端接入某个小区时，则网络设备通过RRC信令将该小区关联的全部CSI-RS资源，一次性全都配置给终端。后续根据终端接入的位置区域不同，通过MAC CE激活终端在对应的CSI-RS资源上测量CSI-RS。在终端接入某个小区时，网络设备执行一次RRC配置即可，无需频繁的进行RRC重配。进一步，在该设计中的方案，在终端接入某个小区时，网络设备需要根据终端在该小区的位置区域不同，发送MAC CE激活对应的CSI-RS，可能需要网络设备多次发送MAC CE信令。但MAC CE信令的开销，要小于RRC配置信令的开销。比如，一次RRC配置的过程包括：下行DCI或下行PDSCH+ACK或NACK+SR+下行DCI+BSR+下行DCI+上行PUSCH(重配完成)，整个过程包括3次下行交互和4次上行交互。一次MAC CE信令的过程，包括：下行DCI或下行PDSCH+上 行ACK或NACK，整个过程包括1次下行交互和1次上行交互。相对于频繁进行RRC重配，采用上述在小区内多次发送MAC CE激活不同位置区域关联的CSI-RS资源的方案，可以减少CSI-RS资源配置的开销。
在一种设计中，所述第一位置区域关联至少一个CSI-RS资源，第二位置区域关联至少一个CSI-RS资源。
第二方面，提供一种资源配置方法，该第二方面与第一方面相对应，有益效果可参见第一方面的记载，该方法的执行主体为网络设备，或者配置于网络设备中的部件(处理器、芯片或其它等)，以网络设备为执行主体为例，该方法包括：在终端接入第一小区的情况下，网络设备向所述终端发送无线资源控制RRC消息，所述RRC消息用于为终端配置N个信道状态信息-参考信号CSI-RS资源。例如，该RRC消息中包括为所述终端配置的CSI-RS资源集，所述CSI-RS资源集中包括N个CSI-RS资源等，N为正整数；网络设备根据所述终端在所述第一小区中的第一位置区域关联的CSI-RS资源，确定所述N个CSI-RS资源中的M1个CSI-RS资源，所述M1个CSI-RS资源中至少包括所述第一位置区域关联的CSI-RS资源，M1为小于或等于N的正整数；网络设备向所述终端发送第一媒体接入控制MAC控制信元CE，所述第一MAC CE用于激活所述终端在同一个周期内，在所述M1个CSI-RS资源上测量CSI-RS。
在一种设计中，所述终端在同一个周期内，最多支持在X个CSI-RS资源上测量所述CSI-RS，X为小于或等于N的正整数。
在一种设计中，在所述终端由所述第一小区中的所述第一位置区域移动到所述第一小区中的第二位置区域情况下，还包括：网络设备根据所述第二位置区域关联的CSI-RS资源，确定所述N个CSI-RS资源中的M2个CSI-RS资源，所述M2个CSI-RS资源中至少包括所述第二位置区域关联的CSI-RS资源，M2为小于或等于N的正整数；网络设备向所述终端发送第二MAC CE，所述第二MAC CE用于激活所述终端在同一个周期内，在所述M2个CSI-RS资源上测量所述CSI-RS。
在一种设计中，还包括：网络设备根据所述第一小区关联的CSI-RS资源，确定所述N个CSI-RS资源。例如，所述N个CSI-RS资源为所述第一小区关联的全部CSI-RS资源。
在一种设计中，所述第一位置区域关联至少一个CSI-RS资源，第二位置区域关联至少一个CSI-RS资源。
第三方面，提供一种资源配置方法，该方法的执体主体为终端，或者配置于终端中的部件(处理器、芯片或其它等)，以终端为执行主体为例，该方法包括：在终端接入第一小区的情况下，终端接收来自网络设备的第一无线资源控制RRC消息，所述第一RRC消息用于为终端配置N1个信道状态信息-参考信号CSI-RS资源。例如，所述第一RRC消息中包括第一CSI-RS资源集，所述第一CSI-RS资源集中包括N1个CSI-RS资源，N1为小于或等于X的正整数，X为所述终端在同一个周期内，支持的CSI-RS资源的最大数量，X为正整数；可选的，所述N1个CSI-RS资源为所述第一小区关联的全部CSI-RS资源。在同一个周期内，终端在所述N1个CSI-RS资源上测量来自所述网络设备的CSI-RS。
通过上述方法，终端在接入第一小区时，网络设备将第一小区关联的CSI-RS资源通过RRC消息，全部配置给终端。终端在RRC消息配置的全部CSI-RS资源上，测量CSI-RS。采用该方案，终端在接入每个小区时，无需频繁进行RRC重配。进一步的，也无需采用MAC CE进行CSI-RS资源的激活，降低CSI-RS资源配置的开销。
在一种设计中，还包括：终端向所述网络设备发送能力信息，所述能力信息用于指示所述终端在同一个周期内，最多支持在X个CSI-RS资源上测量所述CSI-RS。可选的，终端可主动向网络设备上报能力信息，或者，网络设备可发起终端能力查询的命令，终端接收到该查询命令时，再向网络设备上报终端自身的能力等，不作限制。
通过上述设计，网络设备在接收到终端的能力信息时，可判断终端的能力信息中支持的同时测量的X个CSI-RS资源，是否大于一个小区关联的CSI-RS资源。若大于一个小区关联的CSI-RS资源，则表示终端的能力，能够支持终端同时测量一个小区关联的CSI-RS资源，则可将一个小区关联的CSI-RS资源通过RRC消息配置给终端。相应的，终端根据RRC消息的配置，在一个小区关联的CSI-RS资源上测量CSI-RS，终端在一个小区的内部移动时，无需频繁进行RRC重配，节省CSI-RS资源配置的开销。
在一种设计中，还包括：终端接收来自所述网络设备的第一媒体接入控制MAC控制信元CE，所述第一MAC CE用于激活所述终端在同一个周期内，在所述N1个CSI-RS资源上测量所述CSI-RS。
通过上述设计，终端在接收到网络设备的RRC消息时，并不直接根据RRC消息的配置进行CSI-RS测量，而是在接收到MAC CE的激活命令时，再进行相应的CSI-RS测量。通过MAC CE的激活，网络设备可灵活控制终端执行CSI-RS测量的时间。比如，网络设备可预先将第一小区关联的N1个CSI-RS资源配置给终端，但出于某种原因，可在满足某条件时，再让终端开始执行CSI-RS测量。而在上述设计中，通过MAC CE，网络设备可灵活的控制终端开始CSI-RS测量的时间，避免终端进行无效的CSI-RS测量，节省终端的能耗。
在一种设计中，在所述终端由所述第一小区切换到第二小区的情况下，还包括：终端接收来自所述网络设备的第二RRC消息，所述第二RRC消息用于为终端配置N1个CSI-RS资源。例如，所述第二RRC消息中包括第二CSI-RS资源集，所述第二CSI-RS资源集中包括N2个CSI-RS资源，N2为小于或等于X的正整数；可选的，所述N2个CSI-RS资源为所述第二小区关联的全部CSI-RS资源。在同一个周期内，终端在所述N2个CSI-RS资源上测量来自所述网络设备的所述CSI-RS。
通过上述设计，每当终端接入一个小区时，则网络设备将该小区关联的CSI-RS资源配置给终端，后续终端在配置的CSI-RS资源上进行CSI-RS测量，无需频繁进行RRC配置，减少空口开销。
在一种设计中，还包括：终端接收来自所述网络设备的第二MAC CE，所述第二MAC CE用于激活所述终端在同一个周期内，在所述N2个CSI-RS资源上测量所述CSI-RS。
与前述效果相似，终端在接入到一个小区时，网络设备可将该小区关联的CSI-RS资源配置给终端。终端在接收到RRC的配置时，并不直接在RRC配置的CSI-RS资源上执行CSI-RS测量，而是在接收到MAC CE的激活后，再进行CSI-RS测量，从而使得网络设备可灵活的控制终端执行CSI-RS测量的时间，避免终端进行无效的CSI-RS测量。
第四方面，提供一种资源配置方法，该第四方面与第三方面相对应，有益效果可参见第三方面的记载，该方法的执行主体为网络设备，或配置于网络设备中的部件(处理器、芯片或其它等)，以网络设备为执行主体为例，该方法包括：在终端接入第一小区的情况下，网络设备根据所述第一小区关联的信道状态信息-参考信号CSI-RS资源，确定N1个CSI-RS资源，N1为小于或等于X的正整数，X为所述终端在同一个周期内，支持的CSI-RS 资源的最大数量，X为正整数；可选的，所述N1个CSI-RS资源为所述第一小区关联的全部CSI-RS资源。网络设备向所述终端发送第一无线资源控制RRC消息，所述第一RRC消息用于配置终端在同一个周期内，在N1个CSI-RS资源上测量CSI-RS。例如，所述第一RRC消息中包括第一CSI-RS资源集，所述第一CSI-RS资源集中包括所述N1个CSI-RS资源。

具体实施方式
图1是本申请实施例应用的通信系统1000的架构示意图。如图1所示，该通信系统包括无线接入网100和核心网200，可选的，通信系统1000还可以包括互联网300。其中，无线接入网100可以包括至少一个无线接入网设备(如图1中的110a和110b)，还可以包括至少一个终端(如图1中的120a-120j)。终端通过无线的方式与无线接入网设备相连，无线接入网设备通过无线或有线方式与核心网连接。核心网设备与无线接入网设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与无线接入网设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的无线接入网设备的功能。终端和终端之间以及无线接入网设备和无线接入网设备之间可以通过有线或无线的方式相互连接。图1只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备等，在图1中未画出。
无线接入网设备可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、第五代(5th generation，5G)移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。这里的CU完成基站的无线资源控制(radio resource control，RRC)协议和分组数据汇聚层协议(packet data convergence protocol，PDCP)的功能，还可以完成业务数据适配协议(service data adaptation protocol，SDAP)的功能；DU完成基站的无线链路控制(radio link control，RLC)层和介质访问控制(medium access control，MAC)层的功能，还可以完成部分物理(physical，PHY)层或全部物理层的功能，有关上述各个协议层的具体描述，可以参考第三代合作伙伴计划(3rd generation partnership project，3GPP)的相关技术规范。无线接入网设备可以是宏基站(如图1中的110a)，也可以是微基站或室内站(如图1中的110b)，还可以是中继节点或施主节点等。本申请实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以基站作为无线接入网设备的例子进行描述。
终端也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械 臂、智能家居设备等。本申请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。

基站和终端的角色可以是相对的，例如，图1中的直升机或无人机120i可以被配置成移动基站，对于那些通过120i接入到无线接入网100的终端120j来说，终端120i是基站；但对于基站110a来说，120i是终端，即110a与120i之间是通过无线空口协议进行通信的。当然，110a与120i之间也可以是通过基站与基站之间的接口协议进行通信的，此时，相对于110a来说，120i也是基站。因此，基站和终端都可以统一称为通信装置，图1中的110a和110b可以称为具有基站功能的通信装置，图1中的120a-120j可以称为具有终端功能的通信装置。
基站和终端之间、基站和基站之间、终端和终端之间可以通过授权频谱进行通信，也可以通过免授权频谱进行通信，也可以同时通过授权频谱和免授权频谱进行通信；可以通过6千兆赫(gigahertz，GHz)以下的频谱进行通信，也可以通过6GHz以上的频谱进行通信，还可以同时使用6GHz以下的频谱和6GHz以上的频谱进行通信。本申请实施例对无线通信所使用的频谱资源不做限定。
在本申请实施例中，基站的功能也可以由基站中的模块(如芯片)来执行，也可以由包含有基站功能的控制子系统来执行。这里的包含有基站功能的控制子系统可以是智能电网、工业控制、智能交通、智慧城市等上述应用场景中的控制中心。终端的功能也可以由终端中的模块(如芯片或调制解调器)来执行，也可以由包含有终端功能的装置来执行。
在本申请实施例中，基站向终端发送下行信号或下行信息，下行信号或下行信息承载在下行信道上；终端向基站发送上行信号或上行信息，上行信号或上行信息承载在上行信道上。终端为了与基站进行通信，终端与基站控制的小区建立无线连接。与终端建立了无线连接的小区称为该终端的服务小区。在终端与该服务小区进行通信的情况下，还会受到来自邻区的信号的干扰。
在新空口(new radio，NR)系统中，终端向基站报告下行信道质量的流程，包括：基站根据配置发送信道状态信息参考信号(channel-state information reference signal，CSI-RS)。终端对CSI-RS进行测量，并上报测量结果。基站根据上报的测量结果，对下行数据进行调度。所述测量结果包括但不限于以下至少一项：信道质量指示(channel quality indicator，CQI)、预编码矩阵指示(precoding matrix indicator，PMI)或秩指示(rank indication，RI)等，可简称为三种指示(3indicator，3I)测量结果。NR中CSI-RS的总体框架在协议38.214中描述，主要概念有：
1、CSI-RS资源配置(resource setting):指示终端选择哪些CSI-RS资源进行测量并上报测量结果。该CSI-RS资源配置可简称为资源配置。
2、CSI-RS报告配置(reporting setting):指示终端上报测量结果的规则，可包括上报使用的时域资源、频域资源、和上报的测量量等内容。CSI-RS报告配置可简称为报告配置。
其中，每个报告配置关联一个资源配置，可以作为一项测量任务。例如，终端在某资源配置对应的资源上测量CSI-RS，则该终端可按照该资源配置关联的报告配置，向终端上报测量结果。对于报告配置的类型，可以包括周期、非周期或半静态等。可选的，如图2所示，CSI-RS资源配置中包括以下至少一项：
CSI-RS资源配置标识(CSI-RS resource configuration identity，ID)，用于标识CSI-RS资源配置；
CSI-RS资源集列表(CSI-RS resource set list)，包括至少一个CSI-RS资源集。对于周期CSI-RS，包括一个CSI-RS资源集，每个CSI-RS资源集中最多包括8个CSI-RS资源。对于非周期和半静态CSI-RS，包括多个CSI-RS资源集。关于每个CSI-RS资源中配置的参数，可参考协议3GPP TS 38.331中的描述。例如，对于每个CSI-RS资源配置的参数中包括以下至少一项：资源映射配置(resource mapping)、功率控制偏移(power control offset)、功率控制偏移同步信号(synchronization signal，SS)(power control offset SS)、扰码标识(scrambling ID)、周期和偏移配置(periodicity and offset)、或准共址(quasi-co-location，QCL)配置等。所述资源映射配置还可称为CSI-RS图样，所述资源映射配置中包括以下至少一项：时域资源配置、频域资源配置、码分组配置、密度或频域带宽等。所述密度是指CSI-RS传输具体占单个资源块(resource block，RB)上的资源元素(resource element，RE)的数量。比如，CSI-RS传输占用单个RB中的一个RE，则该密度的取值为1。
周期属性，包括周期、非周期和半静态等。对于一个CSI-RS资源配置，若该配置中包括的周期属性为周期，则终端将按周期在该CSI-RS资源配置中包括的CSI-RS资源上测量CSI-RS，该周期的长度是预设的，或者基站预先配置给终端的等，不作限制。或者，若该配置中包括的周期属性为非周期，则终端在接收到基站的触发指令后，在该CSI-RS资源配置中包括的CSI-RS资源上测量一次CSI-RS，该触发指令可以为下行控制信息(downlink control information，DCI)。或者，若该配置中包括的周期属性为半静态，则终端在接收到基站的触发指令后，在该CSI-RS资源配置中包括的CSI-RS资源上周期性的测量CSI-RS，直至接收到基站发送的结束指令为止。
部分带宽(bandwidth part，BWP)ID，用于标识该CSI-RS资源配置对应的CSI-RS在哪一个BWP上传输。
在一种设计中，基站通过RRC消息将上述CSI-RS资源配置和CSI-RS报告配置，配置给终端。例如，基站向终端发送RRC消息，该RRC消息中包括上述CSI-RS资源配置和CSI-RS报告配置。本申请实施例重点关注，对CSI-RS资源配置的过程，后续重点描述通过RRC消息配置CSI-RS资源的过程。
对于周期CSI-RS，终端在接收到上述RRC消息时，可在RRC消息所配置的CSI-RS资源上周期性的测量CSI-RS。例如，对于周期CSI-RS，基站向终端发送RRC消息，该RRC消息中包括一个CSI-RS资源集，该CSI-RS资源集中包括4个CSI-RS资源。终端可根据该RRC的配置，在该4个CSI-RS资源上，周期性的测量CSI-RS。可选的，终端可根据周期(periodicity)和偏移(offset)参数，周期性的测量CSI-RS。上述周期和偏移参数可以是基站通过RRC消息通知终端的，或者预设的，不作限制。以周期参数为4个时隙，偏移参数为3个时隙为例。终端可按照4个时隙为周期，在每4个时隙周期中的第3个时隙，在CSI-RS资源集中包括的4个CSI-RS资源上，分别测量CSI-RS，得到4个测量结果。终端在4个测量结果中，选择一个测量结果，且将该选择的一个测量结果上报给基站。例如，第一个周期，包括时隙0至时隙3，则终端在距离周期起始位置，偏移3个时隙的时隙位置，即时隙2上，在CSI-RS资源集中包括的4个CSI-RS资源上测量CSI-RS。
在NR中，一个小区中可包括多个波束，每个波束关联至少一个CSI-RS资源，终端在接入某个波束时，应该在该波束对应的CSI-RS资源上，测量CSI-RS。在终端高速移动的 情况下，终端会频繁进行波束切换，或者在非地面网络(non-terrestrial network，NTN)卫星通信系统中，在卫星高速移动过程中，即使终端静止不动，终端可能也会被动经历小区覆盖下的多个波束的频繁切换。而前已述，对于周期CSI-RS，CSI-RS资源配置中仅包括一个CSI-RS资源集，CSI-RS资源集中最多包括8个CSI-RS资源。以每个波束关联一个CSI-RS资源为例，按照前述设计，终端每切换8个波束，基站重新为终配置一次CSI-RS资源，即终端每切换8个波束，基站向终端发送一个配置CSI-RS资源的RRC，使得CSI-RS资源配置的空口开销较大。
以NTN系统为例，对上述过程进行说明：在NTN系统中，终端接入的基站是部署在卫星上的。在上行方向上，终端将上行数据发送至部署在卫星上的基站，该基站将上行数据发出，经由一个或多个卫星路由后，发送到部署在地面的信关站，该信关站再将上行数据发送至部署到地面的用户面功能(user plane function，UPF)或其它终端。在下行方向上，部署在地面的UPF将下行数据发送到部署在地面的信关站，信关站将下行数据发出，经由一个或多个卫星的路由后，到达部署在卫星上的基站，然后将下行数据发送给终端。对于轨高为508千米的低轨卫星通信系统，单星的覆盖面积为67万平方公里；考虑星下能满足接入的链路预算余量为8.6分贝，对应波束宽度为4.6度，则星下能满足接入的覆盖面积为1039平方公里，波束个数640+。假设卫星以7.8km/s移动，则卫星会在3分钟内飞过上述覆盖面积1039平方公里，单用户在3分钟会经历50-80个波束。按照目前NR中的设计，每个RRC最多配置8个CSI-RS资源，每个波束关联一个CSI-RS资源，如果用户在3分钟经历80个波束，则在3分钟内，基站向用户发送10个RRC消息。上述仅考虑单用户的情况，如果一个小区内包括2000个用户，针对每个用户，基站在3分钟内发送10个RRC消息进行配置，则CSI-RS资源的配置开销将成倍增加。
对于周期CSI-RS的配置，本申请实施例提供一种资源配置方法，包括：在终端接入某个小区的情况下，将该小区包括的波束关联的CSI-RS资源通过RRC消息一次性全部配置给终端。之后，在终端接入不同的波束的情况下，通过MAC控制信元(control element，CE)激活该波束关联的CSI-RS资源，终端在激活的CSI-RS资源上测量CSI-RS。相对于前述方案中，基站频繁向终端发送RRC消息配置当前接入波束关联的CSI-RS资源，可减小RRC重配信令的开销。如图3所示，提供一种资源配置的流程，至少包括：
步骤300：基站根据第一小区关联的CSI-RS资源，确定N个CSI-RS资源，N为正整数，例如N为大于8的正整数。该步骤300是可选的。
其中，第一小区关联的CSI-RS资源，可指第一小区关联的全部CSI-RS资源。例如，第一小区中包括至少一个波束，每个波束关联一个或多个CSI-RS资源，第一小区关联的全部CSI-RS资源可指第一小区包括的全部波束关联的CSI-RS资源。举例来说，一个小区包括64个波束，每个波束关联一个CSI-RS资源，则该小区关联的全部CSI-RS资源为该小区包括的64个波束关联的64个CSI-RS资源，N的取值可以为64。或者，进一步的，基站在第一小区关联的全部CSI-RS资源中，选择部分CSI-RS资源，作为本申请实施例中的N个CSI-RS资源。例如，基站在上述64个CSI-RS资源中，选择32个CSI-RS资源，N的取值为32。后续通过步骤301中的RRC消息，先将该32个CSI-RS资源配置给终端。之后，在终端接入剩余的32个CSI-RS资源对应的波束的情况下，再将剩余的32个CSI-RS资源配置给终端等，不作限制。
步骤301：在终端接入第一小区的情况下，基站向终端发送RRC消息，所述RRC消 息用于为终端配置N个CSI-RS资源。
以周期CSI-RS为例，RRC消息中包括一个CSI-RS资源集，该CSI-RS资源集中包括N个CSI-RS资源。考虑当前协议中，对于周期CSI-RS，每个CSI-RS资源集中包括的CSI-RS资源的数量限制不超过8个。可选的，在本申请实施例中，可限定N的取值为大于8的正整数。
步骤302：基站根据所述终端在第一小区中的第一位置区域关联的CSI-RS资源，确定所述N个CSI-RS资源中的M1个CSI-RS资源，M1为小于或等于N的正整数。该步骤302是可选的。
示例性的，第一小区内有多个同步信号-物理广播信道块(synchronization signal and physical broadcast channel block，SSB)。第一小区中的一个位置区域可以是一个SSB覆盖的区域，或者将SSB的覆盖区域划分为多个位置区域，也就是一个SSB的覆盖区域内包括多个位置区域，每个位置区域是SSB覆盖区域中的部分区域。
在本申请实施例中，每个位置区域关联至少一个CSI-RS资源。在一个位置区域关联多个CSI-RS资源的情况下，可称该位置区域关联一组CSI-RS资源。在一种可能的实现方式中，在基站检测到终端位于第一小区中的第一位置区域的情况下，基站可确定第一位置区域关联的CSI-RS资源，基站向终端发送第一MAC CE，该第一MAC CE激活终端在第一位置区域关联的CSI-RS资源上测量CSI-RS。在上述步骤302中，第一MAC CE激活的M1个CSI-RS资源中，至少包括第一位置区域关联的CSI-RS资源。可选的，上述M1个CSI-RS资源中，还可以包括其它CSI-RS资源，该其它CSI-RS资源可以是第一位置区域相邻的其它位置区域关联的CSI-RS资源等，不作限制。例如，上述M1个CSI-RS资源中除包括第一位置区域关联的CSI-RS资源外，还可以包括第二位置区域关联的CSI-RS资源和第三位置区域关联的CSI-RS资源等。在一种设计中，基站可根据终端的能力，确定M1的具体取值，终端通过第一MAC CE激活的CSI-RS资源的数量，不应超过终端的能力，所述终端的能力是终端在同一个周期内，在CSI-RS资源上同时检测CSI-RS的能力。例如，终端在同一个周期内，最多支持在4个CSI-RS资源上同时检测CSI-RS，则M1的取值不应超过4。举例来说，每个位置区域关联一个CSI-RS资源，位置区域1至位置区域4分别关联CSI-RS资源1至4，终端在同一个周期内，最多支持在4个CSI-RS资源上检测CSI-RS。在终端位于位置区域1的情况下，基站可向终端发送MAC CE，该MAC CE可激活CSI-RS资源1至CSI-RS资源4。终端在同一个周期内，在CSI-RS资源1至CSI-RS资源4上同时检测CSI-RS。如此设计的好处在于，在终端移动到位置区域2、位置区域3或位置区域4的情况下，基站均无需再发送MAC CE。直至终端移动到位置区域5时，基站才再发送一个MAC CE激活对应的另外4个CSI-RS资源。在上述设计中，基站在通过第一MAC CE激活M1个CSI-RS资源时，除了考虑终端当前的第一位置区域关联的CSI-RS资源外，还考虑终端的能力的影响。因此，上述步骤302的一种实现方式可为：基站根据第一小区中的第一位置区域关联的CSI-RS资源和终端的能力，确定M1个CSI-RS资源。
可选的，位置区域还可称为波束。波束是指基站或终端的发射机或接收机通过天线阵列形成的具有指向性的特殊的发送或接收效果，就像手电筒将光收敛到一个方向形成光束一样。通过波束的形式进行信号的发送和接收，可以有效提升信号的传输距离。波束可以是宽波束，或者窄波束，或者其他类型波束。形成波束的技术可以是波束赋形技术或者其他技术。波束赋形技术具体可以为数字波束赋形技术、模拟波束赋形技术或者混合数字/ 模拟波束赋形技术等。波束一般和资源对应，例如进行波束测量时，基站可通过不同资源的测量结果确定对应波束的质量，例如，终端向基站反馈测得到的资源质量，基站就可以知道对应波束的质量。在数据传输中，波束信息也是通过其对应的资源来进行指示的。例如，基站通过DCI中的传输配置指示(transmission configuration indicator，TCI)字段来指示一个TCI-状态(state)，终端根据该TCI-state中包含的参考信号资源来确定采用该参考资源对应的波束。在通信协议中，波束可以具体表征为数字波束，模拟波束，空域滤波器(spatial domain filter)，空间滤波器(spatial filter)，空间参数(spatial parameter)，TCI，TCI-state等。用于发送信号的波束可以称为发送波束(transmission beam，或Tx beam)，空域发送滤波器(spatial domain transmission filter)，空间发送滤波器(spatial transmission filter)，空域发送参数(spatial domain transmission parameter)，空间发射参数(spatial transmission parameter)等。用于接收信号的波束可以称为接收波束(reception beam，或Rx beam)，空域接收滤波器(spatial domain reception filter)，空间接收滤波器(spatial reception filter)，空域接收参数(spatial domain reception parameter)，空间接收参数(spatial reception parameter)等。或者，天线面板可进行波束赋形，天线面板可形成某个方向的波束，波束也还可以称为天线面板。在协议中，天线面板可以用panel、panel index等来表示。可选的，也可以通过其它方式隐示表示天线面板。例如，天线面板也可以通过天线端口来表示，例如，CSI-RS端口、探测参考信号(sounding reference signal，SRS)端口、解调参考信号(demodulation reference signal，DMRS)端口、相位跟踪参考信号(phase tracking reference signal，PTRS)端口、小区参考信号(cell reference signal，CRS)端口、时频跟踪参考信号(tracking reference signal，TRS)端口、或SSB端口等。或者天线面板可通过天线端口组来表示，天线端口组中包括至少一个天线端口，天线端口组中可包括相同或不同类型的天线端口。可选的，天线端口可通过信道特征表示，例如物理上行控制信道(physical uplink control channel，PUCCH)，物理上行共享信道(physical uplink shared channel，PUSCH)，物理随机接入信道(physical random access channel，PRACH)，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)，物理广播信道(physical broadcast channel，PBCH)等。或者天线端口通过信道组表示，该信道组中包括至少一个信道，该信道组中包括相同类型或不同类型的信道。例如，所述信道组可为控制信道组等。或者，天线端口可以通过以下至少一项表示：QCL，TCI-state，空间关系(spatial relation)，或通过配置在QCL，TCI-state，或spatial relation中的某个索引(index)来表示等。
步骤303：基站向终端发送第一MAC CE，所述第一MAC CE用于激活所述终端在同一个周期内，在N个CSI-RS资源中的M1个CSI-RS资源上测量CSI-RS。
步骤304：终端在同一个周期内，在M1个CSI-RS资源上测量来自基站的CSI-RS。
在一种可能的实现方式中，终端将按周期在M1个CSI-RS资源上测量CSI-RS，并上报测量结果，该周期的时长可以是预设的，或者基站预先通知终端的，不作限制。例如，终端在第一周期内，在M1个CSI-RS资源上，分别测量CSI-RS。在每个CSI-RS资源上测量CSI-RS，分别得到一个对应的测量结果，在上述M1个CSI-RS资源上测量，总共可得到M1个测量结果。在M1个测量结果中，选择出上报给基站的测量结果，上报给基站。基站根据终端上报的测量结果，可调整下行数据的调度策略。例如，终端上报的测量结果较好，代表当前下行信道的质量较佳，可以采用较简单的下行预编码技术；否则，采用较 复杂的下行预编码技术等。后续，在第二周期和第三周期等，终端均按照上述第一周期的方式，进行CSI-RS的测量，并上报测量结果。直至终端移动到第一小区的其它位置区域，例如，第二位置区域，第二位置区域可关联至少一个CSI-RS资源。基站根据第二位置区域关联的CSI-RS资源，在N个CSI-RS资源中确定M2个CSI-RS资源，该M2个CSI-RS资源中至少包括第二位置区域关联的CSI-RS资源，基站向终端发送第二MAC CE，第二MAC CE用于激活终端在M2个CSI-RS资源上测量CSI-RS。终端在同一个周期内，在M2个CSI-RS资源上测量CSI-RS，并上报测量结果。可选的，随着终端的移动，终端可能会移出第一小区的覆盖范围，移动到第二小区的覆盖范围，终端接入的小区将由第一小区切换到第二小区，此时基站可按照前述图3流程中的方法，向终端发送另一个RRC消息，该RRC消息可为终端配置第二小区关联的CSI-RS资源。根据终端在第二小区中所属的位置区域不同，向终端发送MAC CE，激活终端在对应的CSI-RS资源上测量CSI-RS。
前已述，在终端移动到一个新的位置区域的情况下，基站向终端发送MAC CE，该MAC CE除激活当前新的位置区域关联的CSI-RS资源外，还可以激活其它位置区域关联的CSI-RS资源。可选的，在该设计中，并不是终端每移动到一个新的位置区域，基站即对应的向终端发送MAC CE，激活该新位置区域关联的CSI-RS资源。只有当终端新移动到的位置区域相关联的CSI-RS资源并未被激活，或称为终端前一次接收到的MAC CE所激活的M个CSI-RS资源中，不包括新移动到的位置区域相关联的CSI-RS资源时，基站才会再发送一个MAC CE。基站在发送每个MAC CE前，可执行以下判断：确定终端当前移动到的新的位置区域关联的CSI-RS资源，以及前一次发送的MAC CE所激活的CSI-RS资源。当前者的CSI-RS资源，不属于后者CSI-RS资源时，或者称为当后者CSI-RS资源不包括前者CSI-RS资源时，基站才向终端发送MAC CE，激活新位置区域关联的CSI-RS资源。举例来说，一个小区包括位置区域1至5，每个位置区域关联一个CSI-RS资源，位置区域1至5分别关联CSI-RS资源1至5。在终端移动到位置区域1的情况下，设定终端在同一个周期内，最多支持在4个CSI-RS资源上测量CSI-RS，则基站可向终端发送MAC CE1，该MAC CE1激活CSI-RS资源1至CSI-RS资源4。后续只有在终端移动到位置区域5的情况下，基站才会向终端发送MAC CE2，该MAC CE2至少用于激活CSI-RS资源5。或者在另一种方案中，在终端每移动到一个新的位置区域的情况下，基站即向终端发送MAC CE，激活该位置区域对应的CSI-RS资源。在该方案中，MAC CE仅激活当前位置区域关联的CSI-RS资源。沿用上述举例，在终端移动到位置区域1的情况下，基站向终端发送MAC CE1激活位置区域1相关联的CSI-RS1资源；在终端移动到位置区域2的情况下，则基站向终端发送MAC CE2激活位置区域2相关联的CSI-RS2资源等。后续过程相似，不再一一说明。采用前述方案，相对于后述方案，可减少基站发送MAC CE的数量，降低空口开销。
可选的，上述图3流程的应用场景可为：终端在同一个周期内，最多支持在X个CSI-RS资源上测量CSI-RS，X为小于或等于N的正整数。也就是，设定一个小区关联CSI-RS资源的数量为N。终端的能力具体为：终端在同一个周期内，最多支持在X个CSI-RS资源上测量CSI-RS。在X小于N的情况下，终端的能力决定，终端不能在同一个周期内，同时测量第一小区关联的全部CSI-RS资源(即N个CSI-RS资源)。此时可采用上述图3流程中的方案：将一个小区关联的全部CSI-RS资源，通过RRC消息预先配置给终端。基站根据终端的位置区域不同，向终端发送MAC CE，该MAC CE至少激活当前位置区域关联 的CSI-RS资源。通过该方案，在终端接入的小区未作改变的情况下，即终端不切换接入新的小区时，根据终端的位置区域不同，基站通过MAC CE激活对应的CSI-RS资源即可，无需频繁对终端进行RRC重配，减少了配置开销。进一步，一次RRC重配信令交互的过程包括：下行DCI或下行PDSCH+上行肯定确认(acknowledge，ACK)或否定确认(negative acknowledge，NACK)+上行调度请求(scheduling request，SR)+下行DCI+上行缓存状态报告(buffer status repor，BSR)+下行DCI+上行PUSCH(重配完成)，整个过程包括3次下行交互和4次上行交互，一次RRC重配信令的空口开销通常为几十比特。一次MAC CE指示的过程包括下行DCI或下行PDSCH+上行ACK或NACK，整个过程包括1次下行交互和1次上行交互，一次MAC CE指示的空口开销通常为十几比特。由于在本申请实施例的方案中，根据终端的移动区域不同，通过MAC CE激活对应的CSI-RS资源，无需频繁进行RRC重配。因此通过本申请实施例的方法，可将RRC的几十比特的信令开销，降低到十几比特的MAC CE开销，节省了空口资源。
在后续描述中，以位置区域为波束为例，进行说明。在一种设计中，如图4所示，设定一个小区中包括64个波束，每个波束关联一个CSI-RS资源，则可认为该小区关联64个CSI-RS资源。终端的能力包括：在同一个周期内，最多支持在4个CSI-RS资源上测量CSI-RS。基站为终端配置CSI-RS资源的过程：
1、终端接入该小区，基站向终端发送RRC消息，配置终端周期CSI-RS测量，该RRC消息中包括一个CSI-RS资源集，该CSI-RS资源集中包括对应的64个CSI-RS资源。
2、终端的初始接入波束为波束1，基站向终端发送MAC CE，激活CSI-RS资源1至4。
其中，小区中的64个波束的编号分别为波束1至波束64，波束1至波束64关联的CSI-RS资源分别为CSI-RS资源1至CSI-RS资源64。在一种设计中，在终端接入波束1的情况下，该MAC CE至少激活终端在CSI-RS资源1上测量CSI-RS。考虑到终端在同一个周期内，支持最多在4个CSI-RS资源上测量CSI-RS。因此，基站通过MAC CE，可以一次性激活终端在CSI-RS资源1至4上测量CSI-RS。这样，在终端移动到波束5的情况下，基站再向终端发送MAC CE，激活另外4个CSI-RS资源。
3、终端在同一个周期内，在上述4个CSI-RS资源上测量CSI-RS，向基站反馈测量结果。
4、在终端移动到波束5的情况下，或者由于卫星移动导致终端所处于的波束变化到波束5时，向终端发送MAC CE，激活CSI-RS资源5至8。
在该设计中，以通过MAC CE同时激活4个CSI-RS资源为例，终端每移动4个波束，基站即向终端发送一次MAC CE，激活另外4个CSI-RS。在该设计中，通过单次RRC信令将一个小区关联的CSI-RS资源全部配置给终端，之后随着终端在波束间移动，通过MAC CE激活终端能力范围内的多个CSI-RS，终端在激活的CSI-RS资源上测量CSI-RS，从而有效降低RRC重配信令开销。
应当指出，在上述设计中，在终端在同一个周期内，最多支持测量4个CSI-RS资源的情况下，基站通过MAC CE一次激活4个CSI-RS资源为例描述的，并不作为限制。比如，基站通过MAC CE也可以一次激活1、2或3个CSI-RS资源等，但通常不能超过终端的能力。终端通过RRC信令，一次将小区关联的全部64个CSI-RS资源配置给终端，也不作为限制。比如，在初始配置阶段，终端将小区关联的部分CSI-RS资源配置给终端。 例如，前32个波束关联的CSI-RS资源1至CSI-RS资源32。在终端在波束1至波束32间移动的情况下，可通过MAC CE激活对应的CSI-RS。在终端移动到波束33至波束64的情况下，再通过RRC将剩余的32个CSI-RS资源配置给终端。在终端在波束33至波束64间移动的情况下，通过MAC CE激活对应的CSI-RS资源。
在另一种设计中，以一个小区包括64个波束，每个波束关联2个CSI-RS资源为例，每2个CSI-RS资源可认为一组CSI-RS资源。基站为终端配置CSI-RS资源的过程，包括：
1、终端接入小区时，基站向终端发送RRC消息，该RRC消息配置终端周期性测量CSI-RS。该RRC消息中包括一个CSI-RS资源集，该CSI-RS资源集中包括64组CSI-RS资源，每组CSI-RS资源包括2个CSI-RS资源，该CSI-RS资源集可认为包括128个CSI-RS资源。
2、终端接入波束1，考虑到终端在同一个周期最多支持在4个CSI-RS资源上测量CSI-RS，基站向终端发送MAC CE，激活配置的128个CSI-RS资源中的前4个CSI-RS资源，即CSI-RS资源1至CSI-RS资源4。
可以理解的是，在该示例中，由于每个波束关联2个CSI-RS资源，上述MAC CE激活的4个CSI-RS资源，实质上为2组CSI-RS资源，可称为CSI-RS组1至CSI-RS组2，分别对应波束1和波束2。
3、终端在同一个周期内，在CSI-RS资源1至CSI-RS资源4上同时测量CSI-RS，并反馈测量结果。
4、在终端移动到波束3的情况下，或者由于卫星移动导致终端所处的波束变化到波束3时，基站向终端发送MAC CE，该MAC CE用于激活CSI-RS资源5至8。该CSI-RS资源5至8可认为是2组CSI-RS资源，可称为CSI-RS资源组3和CSI-RS资源组4，分别对应波束3和波束4。
后续过程与前述相似，在终端每移动2个波束，或者由于卫星移动导致终端所处的波束变化2个波束的情况下，基站向终端发送一次MAC CE，激活对应的CSI-RS资源。针对小区内包括多个波束，每个波束关联多个CSI-RS的场景，通过单次RRC信令将小区所关联的所有CSI-RS资源均配置给终端，之后随着终端在波束间移动，通过MAC CE激活对应的CSI-RS资源，降低RRC信令开销。在上述描述中，是通过RRC信令一次将小区关联的全部128个CSI-RS资源都配置给终端，后续通过MAC CE激活对应的CSI-RS资源为例说明的。在一种设计中，基站还可以通过RRC信令将小区关联的部分CSI-RS资源配置给终端。比如，该小区的前32个波束关联的64个CSI-RS资源先配置给终端。在终端移到后32个波束的情况下，再通过RRC信令将剩余的64个CSI-RS资源配置给终端。
对于周期CSI-RS的配置，本申请实施例还提供一种资源配置方法，在该方法中主要考虑随着终端能力的提升，在同一个周期内支持CSI-RS资源的数量X，可能会大于一个小区关联的全部CSI-RS资源的场景。在这种场景中，可通过RRC将一个小区关联的全部CSI-RS资源都配置给终端，终端在同一个周期内，直接在小区关联的全部CSI-RS资源上测量CSI-RS，直至终端切换到其它小区时，再进行一次RRC配置。这样，终端在一个小区内，执行一次RRC配置即可，从而减少信令开销。如图5所示，提供一种资源配置的流程，至少包括：
步骤500：在终端接入第一小区的情况下，基站根据第一小区关联的CSI-RS资源，确定N1个CSI-RS资源，N1为小于或等于X的正整数，X为所述终端在同一个周期内，支 持的CSI-RS资源的最大数量，X为正整数。该步骤500是可选的。
可选的，第一小区关联的CSI-RS资源可以为第一小区关联的全部CSI-RS资源。关于第一小区关联的全部CSI-RS资源的说明，可参见图3中的相关说明。设定第一小区关联64个CSI-RS资源，则可将该64个CSI-RS资源，作为N1个CSI-RS资源，通过后续步骤501中的第一RRC消息，配置给终端。
步骤501：基站向终端发送第一RRC消息，所述第一RRC消息用于配置终端在同一个周期内，在N1个CSI-RS资源上测量CSI-RS。例如，所述第一RRC消息包括第一CSI-RS资源集，第一CSI-RS资源集中包括N1个CSI-RS资源。
步骤502：在同一个周期内，终端在N1个CSI-RS资源上测量CSI-RS。
在一种设计中，终端在接收到第一RRC消息时，可直接执行步骤502，在N1个CSI-RS资源上测量CSI-RS。或者，基站可先通过第一RRC，为终端配置N1个CSI-RS资源。之后，基站再向终端发送第一MAC CE，该第一MAC CE用于激活上述N1个CSI-RS资源。在该N1个CSI-RS资源被激活后，终端再在N1个CSI-RS资源上测量CSI-RS，即可选的，在步骤501与步骤502之间还可以包括：基站向终端发送第一MAC CE，该第一MAC CE用于激活终端在同一个周期内，在N1个CSI-RS资源上测量CSI-RS。在本申请实施例中，在终端在第一小区的波束间移动的情况下，或者由于卫星的高速移动，导致终端所处波束发生变生的情况下，无需再进行其它操作。比如，无需再进行目前方案中的RRC重配，也无需像前述图3所示的流程中的通过MAC CE激活当前波束对应的CSI-RS资源的操作，减少信令开销。
可选的，在终端由第一小区切换到第二小区的情况下，基站可根据第二小区关联的CSI-RS资源，确定N2个CSI-RS资源。可选的，该N2个CSI-RS资源为第二小区关联的全部CSI-RS资源。基站向终端发送第二RRC消息，该第二RRC消息用于配置在同一个周期内，终端在N2个CSI-RS资源上测量CSI-RS。终端在接收到第二RRC消息的配置后，在N2个CSI-RS资源上测量CSI-RS。可选的，在终端接收到第二RRC消息，与终端执行CSI-RS测量之间，还可以包括：终端接收来自基站的第二MAC CE，该第二MAC CE用于激活该N2个CSI-RS资源。而终端在接收到N2个CSI-RS资源的激活信令后，再执行CSI-RS测量。后续终端由第二小区切换到其它小区的过程都相似，不再赘述。由于在本申请实施例的方案中，终端在同一个小区的不同波束间切换时，无需其它信令的指示或配置，从而减少信令开销。
可选的，上述图5所示的资源配置方法的一种应用场景包括：设定终端的能力包括：终端在一个周期内，支持CSI-RS资源的最大数量为X，X为正整数。在X的取值大于或等于一个小区关联的全部CSI-RS资源的数量的情况下，则执行图5所示的流程。在前述步骤501中，第一小区关联的全部CSI-RS资源的数量为N1，在本申请实施例中，可限定X的取值大于或等于N1。可选的，终端还可以向基站上报终端的能力。例如，终端向基站发送能力信息，该能力信息用于指示终端在同一个周期内，最多支持在X个CSI-RS资源上测量CSI-RS。而基站可根据终端上报的能力，确定是否执行图5所示的流程。例如，终端上报的能力表明：终端在一个周期内，支持CSI-RS资源的最大数量为X。在X的取值大于或等于终端当前接入小区所关联的全部CSI-RS资源的情况下，执行图5流程中的方法。否则，不再执行。
以一个小区包括64个波束，每个波束关联1个CSI-RS资源，该小区关联64个CSI-RS 资源，终端在同一个周期内，支持CSI-RS资源的最大数量为N，且N的取值大于64为例。如图6所示，基站为终端配置CSI-RS资源的过程，包括：
1、终端接入一个小区时，基站向终端发送RRC消息，该RRC消息配置终端周期性测量CSI-RS。该RRC消息中包括一个CSI-RS资源集，该CSI-RS资源集中包括该小区关联的64个CSI-RS资源。
2、基站向终端发送MAC CE，该MAC CE用于激活上述64个CSI-RS资源。
3、终端在一个周期内，在64个CSI-RS资源上测量CSI-RS，并向基站反馈测量结果。
在该设计中，终端在同一个小区内的不同波束间移动，或者由于卫星移动导致终端所处的波束发生变化时，无需MAC CE进行激活或去激活CSI-RS资源。该设计主要是考虑终端在同一个周期支持CSI-RS资源的数量大于或等于一个小区关联的全部CSI-RS资源的情况，终端支持在同一个周期内，在小区关联的全部CSI-RS资源上测量CSI-RS，则通过RRC消息可将该小区关联的全部CSI-RS资源一次都配置给终端，相应的终端将在该小区关联的全部CSI-RS资源上测量CSI-RS。在终端在同一个小区中所处的波束发生变化的情况下，无需再通过MAC CE进行CSI-RS资源的激活或去激活，节省信令开销。
在上述描述中，是以RRC激活一个小区关联的全部CSI-RS资源为例描述的。在一种设计中，RRC也可以激活一个小区关联的部分CSI-RS资源。即前述图5所示流程中的N1个CSI-RS资源可以是第一小区关联的部分CSI-RS资源，N2个CSI-RS资源可以是第二小区关联的部分CSI-RS资源。例如，N1与N2的取值可以均为32。以一个小区关联的全部CSI-RS资源为64个CSI-RS资源为例。在终端接入当前小区中的波束1的情况下，基站向终端发送RRC1，该RRC1配置终端在同一个周期内，在前32个CSI-RS资源上测量CSI-RS。在终端接入到波束33后，基站向终端发送RRC2，该RRC2配置终端在同一个周期内，在后32个CSI-RS资源上测量CSI-RS。在该种设计中，在一个小区内，基站向终端发送多次RRC消息进行CSI-RS资源的配置。在该设计中，只要RRC消息一次配置的CSI-RS资源的数量大于8个，那么相对于目前方案，还是可以减少RRC配置信令开销的。
在上述描述中，是以本申请实施例的资源配置方法，应用于周期CSI-RS的资源配置为例说明的，并不作为限制。本申请实施例提供的资源配置方法，还可以应用于其它类型的CSI-RS的资源配置。例如，非周期CSI-RS或半静态CSI-RS的资源配置等。例如，对于半静态CSI-RS，在终端接入某个小区的情况下，基站向终端发送RRC消息，该RRC消息中包括多个CSI-RS资源集。之后，基站向终端发送MAC CE，该MAC CE中包括两个信息，一个信息用于指示终端开始周期性测量CSI-RS，另一个信息用于指示多个CSI-RS资源集中的一个CSI-RS资源集。例如，在上述半静态CSI-RS中，应用上述图3所示的资源配置方法时，基站所指示的CSI-RS资源集中可包括终端当前接小区相关联的全部CSI-RS资源；在终端所处的波束变化的情况下，通过MAC CE激活不同的CSI-RS资源，终端在激活的CSI-RS资源上，周期性测量CSI-RS，直至接收到停止周期测量的指令为止。
