技术领域
本发明涉及通信领域，尤其涉及一种资源配置方法及其装置。
背景技术
波束赋形是一种基于天线阵列的信号预处理技术，波束赋形通过调整天线阵列中每个阵元的加权系数产生具有指向性的波束，从而能够获得明显的阵列增益。在新无线(New Radio，NR)中，为了在高频场景下对抗路径损耗，天线阵列更多地会引入波束赋形来获得增益。数据信道、控制信道、同步信号、广播信号都可以通过波束进行发送，因此，波束管理(Beam Management，BM)在NR中显得较为重要。
请参见图1，是现有的NR中下行波束管理各阶段的示意图。如图1所示，波束管理主要分为三个阶段：P-1，P-2和P-3。其中，P-1阶段是系统建立初始波束配对关系(Beam pair link，BPL)的阶段，即建立基站的发送波束与用户设备(User Equipment，UE)的接收波束之间的BPL。经过P-1阶段之后，基站与UE之间初始的基于波束的控制信息和数据的通信链路已建立。P-2阶段和P-3阶段是基于触发，分别对基站的发送波束和UE的接收波束进一步筛选的阶段。
在下行波束配对的过程中，基站配置信道状态信息参考信号(Channel State Information-Reference Signals，CSI-RS)资源，UE根据CSI-RS测量、评估波束质量。为了获得最佳的波束配对，需要将基站的发送波束和UE的接收波束轮巡一遍。若基站的发送波束的波束扫描是周期性的，则UE无论有多少个接收波束，都可以按照预定周期自行逐一轮巡测量并上报，换言之，该场景下基站无需获知UE的接收波束数量，因为其资源配置是周期性的。但是若基站的发送波束扫描是非周期性的，在不知晓UE的可用接收波束的情况下，基站的CSI-RS资源的配置具有一定的盲目性。
目前，基站在不知晓UE的可用接收波束的情况下，可以采用频繁触发的方式进行波束扫描的轮巡，但这样会导致额外的信令和上报开销；或基站按照某个协议约定的最大接收波束数量进行配置，这样则可能造成无线资源的浪费。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。
本发明实施例可以应用于无线通信系统，无线通信系统通常由小区组成，每个小区包含一个基站(Base Station，BS)，基站向多个用户设备提供通信服务，其中基站连接到核心网设备，如图2所示。其中基站包含基带单元(Baseband Unit，BBU)和远端射频单元(Remote Radio Unit，RRU)。BBU和RRU可以放置在不同的地方，例如：RRU拉远，放置于离高话务量的开阔区域，BBU放置于中心机房。BBU和RRU也可以放置在同一机房。BBU和RRU也可以为一个机架下的不同部件。
需要说明的是，本发明实施例提及的无线通信系统包括但不限于：窄带物联网系统 (Narrow Band-Internet of Things，NB-IoT)、全球移动通信系统(Global System for Mobile Communications，GSM)、增强型数据速率GSM演进系统(Enhanced Data rate for GSM Evolution，EDGE)、宽带码分多址系统(Wideband Code Division Multiple Access，WCDMA)、码分多址2000系统(Code Division Multiple Access，CDMA2000)、时分同步码分多址系统(Time Division-Synchronization Code Division Multiple Access，TD-SCDMA)，长期演进系统(Long Term Evolution，LTE)、NR系统以及未来移动通信系统。
本发明实施例中，所述基站是一种部署在无线接入网中用以为用户设备提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点，传输接收点(Transmission Reception Point，TRP)等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB),在第三代(3rd Generation，3G)系统中，称为节点B(Node B，NB)等。为方便描述，本发明所有实施例中，上述为用户设备提供无线通信功能的装置统称为网络设备。
本发明实施例中所涉及到的用户设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述用户设备也可以称为移动台(Mobile Station，MS)、终端(Terminal)，还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能手机(smart phone)、无线数据卡、个人数字助理(Personal Digital Assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handset)、膝上型电脑(laptop computer)、机器类型通信(Machine Type Communication，MTC)终端等。为方便描述，本发明所有实施例中，上面提到的设备统称为用户设备。
下面将对现有的NR中下行波束管理各阶段做简单介绍。现有的NR中上行波束管理各阶段在本发明实施例中不做介绍。
一般而言，现有的NR中下行波束管理分为P-1、P-2和P-3三个阶段。
在P-1阶段，UE可以通过测量选择一个或多个发送波束，与一个或多个接收波束组成波束对(beam pair)。每一个波束对由一个发送波束和一个接收波束组成，发送波束可以来自于一个或多个TRP，接收波束则来自于目标UE。
在P-2阶段，UE可以根据测量结果对一个或多个波束对中的发送波束进行更新。发送波束仍然可以来自于一个或多个TRP，但通常比P-1阶段的候选范围要小。
在P-3阶段，UE可以根据测量结果对一个或多个波束对中的接收波束进行更新。接收波束仍然来自于目标用户本身。
此外，P-2和P-3在流程上可以认为是P-1的子集。
结合图1，P-1阶段是系统建立初始BPL的阶段，即建立TRP发送波束与UE接收波束之间的BPL，该阶段TRP发送波束的波束扫描可能是周期性的(periodic)，也可能是半持续性的(semi-persistent)。P-2阶段和P-3阶段分别是对TRP发送波束和UE接收波束进一步筛选的阶段，这两个阶段TRP发送波束的波束扫描可能是semi-persistent，也可能是不定期的(aperiodic)。需要说明的是，本发明实施例中提到的非周期性的(nonperiodic)为semi-persistent或aperiodic。
上述三个阶段TRP发送波束的波束扫描有可能是非周期性的，导致基站的CSI-RS资 源的配置具有一定的盲目性，目前可能的解决方案具有增加额外信令和上报的开销或浪费无线资源的缺陷。鉴于此，本发明实施例提供一种资源配置方法及其装置，可以有针对性地对波束管理参考信号资源进行配置，具体可以有针对性地对CSI-RS资源进行配置，能够节省信令和上报开销，或节省无线资源。
本发明实施例中的可用接收波束数量仅作为一个描述性用词，描述接收侧在协议允许的一个或多个数值中选择上报的一个数值。该数值的选择可由接收侧自主判断，其具体选择标准或条件在本发明实施例中不作限定。可用接收波束数量可以理解为UE确定的在某个阶段需要通过轮巡方式扫描的接收波束的数量。例如，UE最大能力可支持8个接收波束的轮巡扫描，在某一个阶段，可用接收波束数量可以是8，但在下一个阶段，UE可以基于一些先验信息判断，认为只需轮巡扫描4个接收波束，此时可用接收波束数量便是4，在上述两个不同的阶段，UE上报两个不同的可用接收波束数量。因此，可用接收波束数量可以等同或者不等同于某个阶段的UE最大能力，而是UE可以针对不同的阶段、不同的需求、不同的先验信息做出判断和调整的一个数值。本发明实施例中的可用接收波束数量也并非是唯一的术语表达形式，未来标准中可能以其他的术语表达形式描述，例如，波束扫描资源重复次数，波束扫描辅助系数等等。从技术层面，该术语所描述的内容可以理解为，当UE接收波束参与波束扫描的场景下，通过上报一个数值，便于基站准确地对波束扫描资源进行配置，或对波束扫描结果的上报周期进行配置。例如，在semi-persistent扫描类型下，基站可根据UE上报的数值配置扫描的持续时间；再例如，在aperiodic扫描类型下，基站可根据UE上报的数值配置扫描的触发次数；再例如，基站可根据UE上报的数值，结合基站的待扫描发送波束数量，计算并配置相应的CSI-RS资源；基站可根据UE上报的数值(即可用接收波束数量)，配置CSI-RS资源的数量，具体的，配置相应的CSI-RS资源集中CSI-RS资源的数量(所述CSI-RS资源集包括一个或多个CSI-RS资源)；再例如，基站可根据UE上报的数值(即可用接收波束数量)，配置CSI-RS资源的数量，具体的，配置相应的CSI-RS资源集的测量重复次数；
其中，所述可用接收波束数量与CSI-RS资源的数量相关联，一种实现方式中，CSI-RS资源的数量大于等于可用接收波束数量。CSI-RS资源集的测量重复次数大于等于可用接收波束数量。
再例如，基站可根据UE上报的数值，结合基站的待扫描发送波束数量，计算并配置相应的扫描结果上报周期。应理解，符合上述内容的术语应视为本发明实施例的保护范围。
特别的，在一些实现方式中，UE的可用接收波束可以与发送波束关联，进一步的，UE的接收波束数量可以与发送波束数量关联，所述实现方式可以包括但不限于以下方式中的一种或多种：
例如当UE的收发波束之间存在波束互易性时，可以认为UE的待扫描接收波束数量与发送波束数量相等；
例如当UE的接收和发送射频参数完全一致时，可以认为该UE的额定接收波束数量和额定发送波束数量相等；
例如UE设备在出厂配置中，可能设定UE的额定接收波束数量相比于额定发送波束数量的比例关系或差值，该比例关系或差值可能通过UE能力上报；
例如UE设备在出厂配置中，可能设定UE的接收波束的半功率点波束宽度(Half-power bandwidth,HPBW)相比于发送波束的HPBW的比例关系，该比例关系可能通过UE能力上报；
在以上的一种或多种实现方式中，UE的接收波束数量可以通过发送波束数量推算获得，基站可以根据推算获得的待扫描接收波束数量配置CSI-RS资源或CSI上报周期。
下面将结合附图3-附图7对本发明实施例提供的资源配置方法进行介绍。
请参见图3，图3是本发明实施例提供的一种资源配置方法的流程示意图，图3所示的实施例从网络设备与用户设备交互的角度进行接收，该方法包括但不限于如下步骤：
步骤S101：用户设备确定所述用户设备的可用接收波束数量；
具体地，UE的可用接收波束数量一方面受限于自身的能力，另一方面也受应用场景的影响。应用场景包括非周期波束扫描或周期性波束扫描发生在基站与UE已建立控制信息和数据的通信链路之后的场景(P-1阶段已建立)，非周期波束扫描或周期性波束扫描发生在基站与UE还没建立控制信息和数据的通信链路之前的场景(P-1阶段还未建立)，UE完成小区搜索的场景。假如UE自身能力较弱，此时是何种应用场景，它都可能只有一个全向的波束用于接收。假如UE可以打出8个不同方向的波束，但这只是一种自身能力的体现，实际应用中，UE可以根据之前小区搜索过程中所获得的先验信息，缩小其搜索可用接收波束的范围。示例性地，8个波束可能覆盖了360°，而实际应用中，UE在小区接入时对接入波束有了先验信息，之后的数据传输的接收波束可能会在有限的角度范围内搜索。例如，UE在小区接入时使用接收波束3，可搜索与接收波束3相距一定角度的接收波束，进而根据搜索到的接收波束确定UE的可用接收波束数量。
另一种可能的应用场景为，UE有多个天线端口，其中全部或部分天线端口可以独立波束赋形，例如，全部或部分天线端口分别对应不同的射频通道，而这些射频通道可能位于不同的天线面板上。在该应用场景中，所述可以独立波束赋形的天线端口所对应的可用接收波束数量可能一致，也可能不一致，其中，这些不同天线端口所对应的接收波束可能同时扫描，也可能顺序扫描，还可能使用其他可实现的扫描方式。此时，UE可确定这些天线端口必须通过轮巡接收的最大接收波束数量，将其作为UE的可用接收波束数量。例如，UE有两个可以独立波束赋形的天线端口，天线端口1对应4个可用接收波束，天线端口对应3个可用接收波束，这两个天线端口所对应的接收波束同时扫描，那么UE可确定这两个天线端口必须通过轮巡接收的最大接收波束数量为4个，将4作为UE的可用接收波束数量。
在所述用户设备接收到网络设备发送的用户能力查询请求消息的情况下，所述用户设备可将所述用户设备的接收波束能力所指示的可支持接收波束的最大数量确定为所述用户设备的可用接收波束数量。其中，接收波束能力指示UE可支持接收波束的最大数量，不同UE的接收波束能力有所差别。所述用户设备可支持接收波束的最大数量为所述用户设备的可用接收波束数量。所述用户能力查询请求消息可以为UE能力查询命令，用于查询UE的各项能力，包括现有的五项能力和接收波束能力，五项能力包括演进型通用地面无线接入(Evolved Universal Terrestrial Radio Access，EUTRA)能力、通用地面无线接入(Universal Terrestrial Radio Access，UTRA)能力、通用无线接入网电路交换(General Radio Access  Network Circuit Switch，GRAN-CS)能力、通用无线接入网分组交换(General Radio Access Network Packet Switch，GRAN-PS)能力、CDMA2000-1x无线传输技术(Radio Transmission Technology，RTT)能力。所述用户能力查询请求消息为所述用户设备在完成小区搜索时，由所述网络设备向所述用户设备发送。
在所述用户设备通过小区搜索获取到先验信息的情况下，所述用户设备可根据先验信息确定所述用户设备的可用接收波束数量。所述用户设备根据先验信息确定所述用户设备的可用接收波束数量的方法在此不作限定，例如，可根据与小区接入时的接入波束相距一定角度的接收波束来确定。
在所述用户设备没有任何先验信息的情况下，所述用户设备可将小区搜索时所使用接收波束确定为可用接收波束，从而确定所述用户设备的可用接收波束数量，此时可能只有一个可用接收波束。
步骤S102：所述用户设备向网络设备发送接收波束数量指示信息，所述接收波束数量指示信息指示所述用户设备的可用接收波束数量；
具体地，在确定所述用户设备的可用接收波束数量后，向所述网络设备发送接收波束数量指示信息，所述接收波束数量指示信息指示所述用户设备的可用接收波束数量。所述接收波束数量指示信息可采用N比特对所述用户设备的可用接收波束数量进行指示，可以指示2N种具体数量或2N种数量区间，N的具体数值视具体情况而定。特别需要说明的是，UE允许上报的可用接收波束的最大数量受协议约束，即可以由N的具体数值和指示的具体方式共同限制。
示例性地，所述接收波束数量指示信息采用2比特对所述用户设备的可用接收波束数量的具体数量进行指示，可参见下表：
Signaling #of Rx Beams
00 1(Beam)
01 2(Beams)
10 3(Beams)
11 4(Beams)
例如，所述接收波束数量指示信息为“10”，指示所述用户设备的可用接收波束数量为3个。此时，UE允许上报的可用接收波束的最大数量为4。
示例性地，所述接收波束数量指示信息采用2比特对所述用户设备的可用接收波束数量的数量区间进行指示，可参见下表：
Signaling #of Rx Beams
00 1(Beam)
01 2(Beams)
10 4(Beams)
11 8(Beams)
例如，所述接收波束数量指示信息为“10”，指示所述用户设备的可用接收波束数量的数量区间为[3,4]，即可用接收波束数量为3个或4个。再例如，所述接收波束数量指示信息为“11”，指示数量区间[5,8]，即可用接收波束数量为5个或6个或7个或8个。此时， UE允许上报的可用接收波束的最大数量为8。
在一种可能实现的方式中，所述用户设备通过上行控制信息(Uplink Control Information，UCI)向所述网络设备发送所述接收波束数量指示信息，即所述接收波束数量指示信息携带在所述UCI中。可选地，所述UCI还包括其它信息，例如信道质量指示(Channel Quality Indicator，CQI)、秩指示(Rank Indication，RI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)等信息。
可以认为的是，在该种可能实现的方式中，系统已经建立了初始的基于波束的控制信息和数据的通信链路，所述用户设备向所述网络设备发送所述UCI，可参见图4所示的上报接收波束数量指示信息示例图，UE向NB发送UCI，UCI携带的接收波束数量指示信息为“10”，若指示具体数量，则指示UE的可用接收波束数量为3个；若指示数量区间，则指示UE的可用接收波束数量为3个或4个。可选地，所述网络设备通过非周期触发方式触发所述用户设备向所述网络设备发送所述UCI，非周期触发方式可以由下行控制信息(Downlink Control Information，DCI)触发。所述UCI可携带波束相关报告(beam-related reporting)，所述波束相关报告可携带所述接收波束数量指示信息。所述接收波束数量指示信息也可独立于所述波束相关报告携带在所述UCI中，例如所述接收波束数量指示信息可通过某一个预定义的UCI格式中的M比特指示，或通过其他形式指示。所述UCI的传输信道可为物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，也可为物理上行控制信道(Physical Uplink Control Channel，PUCCH)，还可以为未来通信系统定义的其他具有相同功能的上行信道。
在一种可能实现的方式中，所述用户设备通过物理随机接入信道(Physical Random Access Channel，PRACH)消息向所述网络设备发送所述接收波束数量指示信息，即所述接收波束数量指示信息携带在所述PRACH消息中。其中，所述PRACH消息可以为无线资源控制(Radio Resource Control，RRC)连接请求消息，即随机接入过程中的message 3；也可以为具有信息负载(payload)能力的随机接入前导消息，即随机接入过程中的message 1，与LTE系统的message 1不同的是，这里的message 1具有信息负载能力，能够携带信息。可以理解的是，若message 1不具有信息负载能力，则可以在message 3中携带所述接收波束数量指示信息；若message 1具有信息负载能力，则可以在message 1中携带所述接收波束数量指示信息。
可以认为的是，该种可能实现的方式中，系统还未建立初始的基于波束的控制信息和数据的通信链路，所述用户设备不能通过所述UCI向所述网络设备发送所述接收波束数量指示信息。所述用户设备在小区搜索(cell acquisition)过程中，通过所述PRACH消息向所述网络设备发送所述接收波束数量指示信息，可参见图5所示的上报接收波束数量指示信息示例图，UE在小区搜索(cell acquisition)过程中，向NB发送PRACH消息，PRACH消息携带的接收波束数量指示信息为“00”，指示UE的可用接收波束数量为1个。
在一种可能实现的方式中，所述用户设备在接收到网络设备发送的用户能力查询请求消息时，可将所述用户设备的接收波束能力所指示的可支持接收波束的最大数量确定为所述用户设备的可用接收波束数量，通过用户能力查询响应消息向所述网络设备发送接收波束数量指示信息，即所述接收波束数量指示信息携带在所述用户能力查询响应消息中。可 选地，所述用户能力查询响应消息还包括现有的五项能力。
步骤S103：所述网络设备接收所述用户设备发送的所述接收波束数量指示信息；
具体地，所述网络设备根据所述接收波束数量指示信息的载体来接收所述接收波束数量指示信息。
在一种可能实现的方式中，在系统已经建立了初始的基于波束的控制信息和数据的通信链路的情况下，通过所述用户设备发送的所述UCI来接收所述接收波束数量指示信息。
在一种可能实现的方式中，在系统还未建立初始的基于波束的控制信息和数据的通信链路的情况下，通过所述用户设备发送的message 1或message 3来接收所述接收波束数量指示信息。
在一种可能实现的方式中，在发送所述用户能力查询请求消息的情况下，通过所述用户设备发送的所述用户能力查询响应消息来接收所述接收波束数量指示信息。
步骤S104，所述网络设备根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行波束管理参考信号资源的配置；
具体地，所述网络设备可根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行配置。在一种可能实现的方式中，所述网络设备可根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行波束管理参考信号资源的配置。在一种可能实现的方式中，所述网络设备可根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行波束测量上报参数的配置。所述网络设备还可以根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行除上述两种配置之外的其他波束扫描相关的配置。
下面将对上述两种配置进行介绍，首先介绍所述网络设备可根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行波束管理参考信号资源的配置。此时的配置可以应用于非周期性波束扫描的场景下的资源配置。
其中，所述波束管理参考信号用于所述用户设备测量波束质量，可以为CSI-RS，也可以为其它用于UE测量波束质量的参考信号。
所述波束管理参考信号以CSI-RS为例，所述网络设备根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量确定所需的CSI-RS资源的数量，并根据所述CSI-RS资源的数量进行所述CSI-RS资源的配置。其中，所述网络设备的发送波束数量可为针对所述用户设备的可用发送波束数量。假设所述用户设备的可用接收波束数量为2个，所述网络设备的发送波束数量为4个，在不考虑复用的情况下，所需的CSI-RS资源的数量为8个，所述网络设备对这8个CSI-RS资源的时频位置、端口等进行配置；在考虑复用的情况下，根据复用方式确定所需CSI-RS资源的数量，并对这些CSI-RS资源的复用方式、时频位置、端口等进行配置。所述网络设备在对CSI-RS资源进行配置的过程中，除根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行配置外，还可以根据根据所述用户设备的可用接收波束数量、所述网络设备的发送波束数量和其他参数进行配置。
可选地，所述网络设备可进行一次或多次配置。例如，图4中所述接收波束指示信息为“10”，指示可用接收波束数量为3个，所述网络设备连续触发3次发送波束扫描，对应地进行3次配置；所述网络设备也可触发一次发送波束扫描，对应地进行一次配置。再例 如，图5中所述接收波束指示信息为“00”，指示可用接收波束数量为1个，所述网络设备只触发一次发送波束扫描，对应地进行一次配置。
可选地，所述波束管理参考信号以CSI-RS为例，所述网络设备在完成配置后，向所述用户设备发送所述CSI-RS资源的配置信息，以便所述用户设备根据所述配置信息获取所述CSI-RS进行波束质量的测量。
作为一个可选的实施例，所述网络设备可以预设UE的可用接收波束数量阈值，具体数值不作限定，例如可用接收波束数量阈值为8个。若所述接收波束数量指示信息所指示的可用接收波束数量小于所述可用接收波束数量阈值，则所述网络设备可根据所指示的可用接收波束数量和所述网络设备的发送波束数量进行波束管理参考信号资源的配置，例如，所指示的可用接收波束数量为4个，可用接收波束数量阈值为8个，所述网络设备根据4个可用接收波束和所述网络设备的发送波束数量进行CSI-RS资源的配置。若所述接收波束数量指示信息所指示的可用接收波束数量大于或等于所述可用接收波束数量阈值，则所述网络设备可根据所述可用接收波束数量阈值和所述网络设备的发送波束数量进行波束管理参考信号资源的配置，例如，所指示的可用接收波束数量为32个，可用接收波束数量阈值为8个，所述网络设备可根据8个可用接收波束和所述网络设备的发送波束数量进行CSI-RS资源的配置；或所述网络设备可根据比所述可用接收波束数量阈值小的可用接收波束数量和所述网络设备的发送波束数量进行波束管理参考信号资源的配置，比所述可用接收波束数量阈值小的可用接收波束数量的具体数值由所述网络设备选取，例如所指示的可用接收波束数量为32个，可用接收波束数量阈值为8个，所述网络设备可根据4个可用接收波束和所述网络设备的发送波束数量进行CSI-RS资源的配置。
需要说明的是，上述可选的实施例中，接收波束数量指示信息所指示的可用接收波束数量的最大值受协议约束，基站可通过设置阈值，进一步对接收波束数量进行限定。各个基站设置的阈值可能相同，也可能不相同，在此不作限定。
其次介绍所述网络设备可根据所述用户设备的可用接收波束数量和所述网络设备的发送波束数量进行波束测量上报参数的配置。此时的配置可以应用于周期性波束扫描的场景下的上报配置。
目前，从波束测量上报的角度分析，基站会通过高层信令配置波束测量上报的各项参数。在周期性波束扫描的场景下，基站在没有获知UE的接收波束数量的情况下，可能默认配置UE在每个接收波束扫描完发送波束之后，进行波束测量结果上报，这样可能会占用过多的上行资源。鉴于此，本发明实施例提出基站根据接收波束数量和发送波束数量进行波束测量上报参数的配置，可以避免占用过多的上行资源。
其中，所述波束测量上报参数可以基于CSI-RS的测量上报参数，也可以是基于其他测量参考信号的测量上报参数。所述波束测量上报参数可以包括上报周期、波束测量结果类型(CSI-RS资源指示(CSI-RS resource index，CRI)、参考信号接收功率(Reference Signal Receiving Power，RSRP)等)等。
在周期性波束扫描的场景下，所述网络设备会根据其发送波束数量进行CSI-RS资源的配置，并按照一个预定的周期进行重复扫描。此时所述网络设备可以根据其发送波束数量和UE的可用接收波束数量配置上报周期。可选地，上报周期可以配置为UE在完整的轮巡 扫描完成之后，进行上报，例如，基站有4个发送波束，UE有2个可用接收波束，基站在配置上报周期的时，指示UE在完成所有的发送波束与接收波束的配对扫描之后，例如8次配对扫描之后，集中上报一次波束测量结果，这样可以避免不必要的上报，可以合理利用上行资源。可选地，上报周期还可以配置为UE每个预定的周期都上报一次，例如，基站有4个发送波束，UE有2个接收波束，在执行完4个发送波束与接收波束1的配对扫描之后，先上报一次波束测量结果，再执行4个发送波束与接收波束2的配对扫描之后，再上报一次波束测量结果。
作为一个可选的实施例，所述网络设备可以预设UE的可用接收波束数量阈值，具体数值不作限定，例如可用接收波束数量阈值为8个。若所述接收波束数量指示信息所指示的可用接收波束数量小于所述可用接收波束数量阈值，则所述网络设备可根据所指示的可用接收波束数量和所述网络设备的发送波束数量进行上报周期的配置。若所述接收波束数量指示信息所指示的可用接收波束数量大于或等于所述可用接收波束数量阈值，则所述网络设备可根据所述可用接收波束数量阈值和所述网络设备的发送波束数量进行上报周期的配置。
需要说明的是，上述可选的实施例中，接收波束数量指示信息所指示的可用接收波束数量的最大值受协议约束，基站可通过设置阈值，进一步对接收波束数量进行限定。各个基站设置的阈值可能相同，也可能不相同，在此不作限定。
在图3所示的实施例中，通过用户设备向网络设备上报可用接收波束数量，以便网络设备根据可用接收波束数量和发送波束数量进行波束管理参考信号资源的配置，具体可进行CSI-RS资源的配置，由于网络设备可以准确地知道接收波束数量，因此可以在完整的波束扫描配对之后，才触发一次波束相关信息的上报，节省了信令和上报开销；亦或者相比按照某个协议约定的最大接收波束数量进行配置，可以节省无线资源。
请参见图6，图6是本发明实施例提供的另一种资源配置方法的流程示意图，图6所示的实施例从网络设备与用户设备交互的角度进行接收，该方法包括但不限于如下步骤：
步骤S201：网络设备向用户设备发送接收波束数量指示信息，所述接收波束数量指示信息指示所述网络设备规定的所述用户设备可用于波束扫描配对的最大允许接收波束数量；
具体地，所述网络设备为某一UE触发波束扫描的时候，会影响到其它UE的数据通信调度，因此所述网络设备可以根据当前业务和场景等信息，规定特定UE可用于波束扫描配对的最大允许接收波束数量。所述网络设备还可通过其它方法来规定所述用户设备可用于波束扫描配对的最大允许接收波束数量。
所述网络设备向所述用户设备发送接收波束数量指示信息，所述接收波束数量指示信息指示所述最大允许接收波束数量，以便所述用户设备根据所述最大允许接收波束数量来选择接收波束。所述接收波束数量指示信息可采用N比特对所述最大允许接收波束数量进行指示，可以指示2N种具体数量或2N种数量区间，N的具体数值视具体情况而定。
示例性地，所述接收波束数量指示信息采用2比特对所述最大允许接收波束数量的具体数量进行指示，可参见下表：
Signaling #of Rx Beams
00 1(Beam)
01 2(Beams)
10 3(Beams)
11 4(Beams)
例如，所述接收波束数量指示信息为“10”，指示所述网络设备规定的所述用户设备可用于波束扫描配对的最大允许接收波束数量为3个。
示例性地，所述接收波束数量指示信息采用2比特对所述最大允许接收波束数量的数量区间进行指示，可参见下表：
Signaling #of Rx Beams
00 1(Beam)
01 2(Beams)
10 4(Beams)
11 8(Beams)
例如，所述接收波束数量指示信息为“10”，指示所述网络设备规定的所述用户设备可用于波束扫描配对的最大允许接收波束数量为4个。再例如，所述接收波束数量指示信息为“11”，指示数量区间[5,8]，最小值为5，最大值为8，此时可不关注最小值，只关注最大值。
所述网络设备在建立初始的基于波束的控制信息和数据的通信链路之后，向所述用户设备发送所述接收波束数量指示信息，可参见图7所示的接收波束数量指示信息下发示例图，NB向UE发送接收波束数量指示信息“10”，若指示具体数量，则通知该UE，所述网络设备规定该UE最大只允许3个接收波束进行波束扫描配对；若指示数量区间，则通知该UE，所述网络设备规定该UE最大只允许4个接收波束进行波束扫描配对。
在一种可能实现的方式中，所述网络设备通过RRC信令向所述用户设备发送所述接收波束数量指示信息，即所述接收波束数量指示信息携带在所述RRC信令中。所述RRC信令属于第三层(Layer 3)信令，其通常是一些控制消息。L3信令的发送周期或者控制周期通常较长，适用于发送一些不会频繁发生变化的信息，例如，在现有的一些通信标准中，L3信令通常用于承载一些配置信息。所述接收波束数量指示信息也可以通过RRC信令之外的其他第三层信令发送。
在一种可能实现的方式中，所述网络设备通过媒体接入控制(Media Access Control，MAC)信令向所述用户设备发送所述接收波束数量指示信息，即所述接收波束数量指示信息携带在所述MAC信令中。所述MAC信令属于第二层(Layer 2)信令，其通常可以由，例如但不限于，第二层帧的帧头来承载。上述帧头中还可能携带，例如但不限于，源地址和目的地址等信息。除帧头外，第二层帧通常还包含帧体。在一些情况下，L2信令也可以由第二层帧的帧体来承载。第二层信令的典型例子是802.11系列标准中MAC帧的帧头中的帧控制(Frame Control)字段中携带的信令，或者一些协议中定义的MAC控制实体(Control Entity，MAC)。第二层帧通常可以携带在物理层帧的数据部分。所述MAC信令可以为媒体接入控制控制元素(Media Access Control-Control Element，MAC-CE)，所述接收波束数量指示信息也可以通过所述MAC信令之外的其他第二层信令发送。
在一种可能实现的方式中，所述网络设备通过下行控制信息向所述用户设备发送所述接收波束数量指示信息，即所述接收波束数量指示信息携带在所述下行控制信息中。所述下行控制信息可称为物理层信令，也称为第一层(Layer 1，L1)信令，其通常可以由物理层帧中的控制部分来承载。所述接收波束数量指示信息也可以通过所述下行控制信息之外的其他第一层信令发送。
步骤S202：所述网络设备根据所述最大允许接收波束数量和所述网络设备的发送波束数量进行波束管理参考信号资源的配置；
图6所示实施例中的步骤S202的实现过程与图3所示实施例中步骤S104的类似，不同之处在于，步骤S202是最大允许接收波束数量，步骤S104是可用接收波束数量。
需要说明的是，步骤S201与步骤S202执行的先后顺序不限定于先步骤S201，再步骤S202，可同时执行，即在进行资源配置的同时向所述用户设备发送所述接收波束数量指示信息，也可先执行步骤S202，再执行步骤S201。
步骤S203：所述用户设备接收所述网络设备发送的所述接收波束数量指示信息；
具体地，所述用户设备通过所述接收波束数量指示信息的载体来接收所述接收波束数量指示信息。
在一种可能实现的方式中，所述用户设备通过所述RRC信令或其它第三层信令来接收所述接收波束数量指示信息。
在一种可能实现的方式中，所述通过设备通过所述MAC信令或其它第二层信令来接收所述接收波束数量指示信息。
在一种可能实现的方式中，所述通过设备通过所述下行控制信息或其它第一层信令来接收所述接收波束数量指示信息。
步骤S204：所述用户设备根据所述最大允许接收波束数量选择接收波束；
具体地，所述用户设备获取所述用户设备的可用接收波束数量，若所述用户设备的可用接收波束数量大于所述最大允许接收波束数量，则从所述用户设备的可用接收波束中选择与所述最大允许接收波束数量相同数量的接收波束，例如，所述最大允许接收波束数量为4个，所述用户设备的可用接收波束数量为5个，则从5个可用接收波束中选择4个接收波束，具体地选择方法在此不作限定，只需选择4个接收波束即可。若所述用户设备的可用接收波束数量小于或等于所述最大允许接收波束数量，则所述用户设备选择所有所述用户设备的可用接收波束，例如，所述用户设备的最大允许接收波束数量为4个，所述用户设备的可用接收波束数量为3个，则将3个可用接收波束全选。
对于所述用户设备的可用接收波束数量小于所述最大允许接收波束数量的情况，所述网络设备在进行资源配置时，可能会造成一些无线资源的浪费，例如，所述用户设备的最大允许接收波束数量为4个，所述网络设备根据4个接收波束进行资源配置，但是所述用户设备的可用接收波束数量为3个，可能会浪费一些接收波束资源。
虽然通过所述网络设备来约束所述用户设备的接收波束数量，下发的所述接收波束数量指示信息可能会造成一些无线资源的浪费，但是可以在完整的波束扫描配对之后，才触发一次波束相关信息的上报，节省了信令和上报开销；亦或者比按照某个协议约定的最大接收波束数量进行配置浪费的无线资源少。
在选择接收波束之后，所述用户设备根据选择的接收波束与所述网络设备的发送波束进行波束扫描配对。例如，所述最大允许接收波束数量为4个，所述用户设备的可用接收波束数量为5个，则将从5个可用接收波束中选择的4个接收波束与所述网络设备的发送波束进行波束扫描配对；所述用户设备的最大允许接收波束数量为4个，所述用户设备的可用接收波束数量为3个，则将全选的3个可用接收波束与所述网络设备的发送波束进行波束扫描配对。
所述波束管理参考信号以CSI-RS为例，在完成波束扫描配对后，所述用户设备可通过波束配对关系接收所述网络设备发送的所述CSI-RS资源的配置信息，并根据所述配置信息获取所述CSI-RS，并进行波束质量的测量。
在图6所示的实施例中，通过网络设备对用户设备可用于波束扫描配对的最大允许接收波束数量进行约束，实现网络设备根据最大允许接收波束数量和发送波束数量进行波束管理参考信号资源的配置，具体可实现CSI-RS资源的配置，可以在完整的波束扫描配对之后，才触发一次波束相关信息的上报，节省了信令和上报开销；亦或者相比按照某个协议约定的最大接收波束数量进行配置，可以节省无线资源。
需要说明的是，图3所示的实施例，由用户设备通知网络设备可用接收波束数量，图6所示的实施例，由网络设备约束用户设备的最大允许接收波束数量，两个实施例都可以达到节省信令和上报开销，或节省无线资源的目的，具体实施哪个实施例视具体情况而定。
作为一个可选的实施例，协议可以定义一个阈值Y，该阈值可以作为波束扫描时UE的可用接收波束数量的默认值，该阈值具体数值不作限定。对于所有的基站，所有的UE而言，该阈值是固定的，可知的。基站默认根据其发送波束数量和Y进行扫描相关的配置(例如CSI-RS资源配置、上报周期配置等)。若UE的实际可用接收波束数量大于或等于Y，则UE可以从实际可用接收波束中至多选择Y个可用接收波束进行波束扫描，例如，UE的实际可用接收波束数量为4个，而Y＝2，则UE从4个实际可用接收波束中至多选择2个可用接收波束进行波束扫描。若UE的实际可用接收波束数量小于Y，则UE可以根据其实际可用接收波束数量进行波束扫描。
可选地，虽然协议定义了阈值Y，基站也可以选用比Y小的阈值Y’，并将选用的Y’告知UE，以便UE在其实际可用接收波束数量大于或等于Y’时，可以从实际可用接收波束中至多选择Y’个可用接收波束进行波束扫描。
需要说明的是，上述可选的实施例中，由于协议已经定义了基站配置资源或上报周期的默认值，因此UE可以不向基站反馈UE的实际可用接收波束数量。
