技术领域
本申请涉及通信领域，尤其涉及一种波束测量方法、装置及系统。
背景技术
在第五代(5th generation，5G)移动通信系统的在下行传输和上行传输中，网络设备和终端具体采用什么波束可以通过波束管理流程确定。例如，网络设备可以采用网络设备的波束依次发送对应的测量资源，终端可以采用终端的波束接收测量资源，以确定测量资源对应的终端最佳波束。终端可以将终端最佳波束对应的测量资源的信息上报给网络设备，以便网络设备确定网络设备采用什么波束进行发送，终端采用什么波束进行接收是较佳的。
为提高上行传输可靠性，目前标准正在讨论如何通过终端的多天线面板实现多波束同传。此时，一个测量资源对应的终端的波束可能有多个，网络设备如何确定这多个波束，以实现对多波束同传的有效调度，是目前研究的热点问题。
发明内容
本申请实施例提供一种波束测量方法、装置及系统，用以实现网络设备能够确定用于多个波束同发的波束。
为达到上述目的，本申请采用如下技术方案：
第一方面，提供一种波束测量方法，该方法包括：终端接收来自网络设备的配置信息，并根据配置信息，向网络设备发送第一测量资源对的信息。配置信息用于指示终端向网络设备发送测量资源对的信息，测量资源对包括两个测量资源，两个测量资源对应的终端的两个波束能同时用于上行传输。第一测量资源对包括第一测量资源和第二测量资源，第一测量资源和第二测量资源对应的终端的两个波束能同时用于上行传输。
基于第一方面所述的方法可知，终端可以根据配置信息的指示，向网络设备上报测量资源对，以便网络设备能够根据测量资源对，确定终端有两个波束能用于终端同时执行上行传输，也即，实现网络设备能够确定用于多个波束同发的波束，从而实现对多波束同传的有效调度。
一种可能的设计方案中，配置信息还用于指示多个测量资源，终端根据配置信息，向网络设备发送第一测量资源对的信息，包括：终端根据配置信息，接收来自网络设备的多个测量资源，并根据配置信息，向网络设备发送多个测量资源中第一测量资源对的信息。可以看出，在波束测量过程中，网络设备可以不用指定终端具体上报哪两个资源，终端可以根据实际需求选择对应的两个测量资源进行上报，以满足实际需求。例如，终端可以上报平均信号质量最强的两个资源。
可选地，第一测量资源是终端使用终端的第一波束接收的测量资源中，信号质量大于预设质量的测量资源，第二测量资源是终端使用终端的第二波束接收的测量资源中，信号质量大于质量阈值的测量资源。可以理解，由于第一测量资源和第二测量资源都可以是信号质量比较强的测量资源，网络设备通过调度第一测量资源和第二测量资源来指示终端执行上行同传，可以保障传输质量。
进一步的，第一测量资源对的信息包括如下至少一项：第一测量资源的标识、第一测量资源的参考信号接收功率RSRP、第二测量资源的标识，或第二测量资源的RSRP，用以准确指示第一测量资源和第二测量资源的质量，或者也可以通过其他可能的信息指示这两个测量资源的质量，不做限定。
一种可能的设计方案中，第一方面所述的方法还可以包括：终端接收来自网络设备的指示信息。其中，指示信息用于指示：终端使用第一测量资源和第二测量资源对应的终端的两个波束，同时进行上行传输。也就是说，终端是否采用多波束同传可以由网络设备通过指示信息来灵活调 度，以实现按需执行多波束同传。
可以理解，第一测量资源和第二测量资源可以是相同，或者不同的测量资源。第一测量资源可以对应的终端的第一波束，第二测量资源可以对应的终端的第二波束，也即，同一个测量资源可以对应终端的两个不同的波束，或者不同的两个测量资源分别对应终端的两个不同的波束，具体不做限定。
可选地，指示信息可以包括第一测量资源的标识和第二测量资源的标识。可以理解，通过波束测量，终端可以维护测量资源对和波束的映射关系。这样，即使网络设备指示测量资源对，终端也可以确定对应的两个波束，从而可以降低指示开销。

具体实施方式
方便理解，下面先介绍本申请实施例所涉及的技术术语。
1、波束：
波束是指网络设备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，类似于手电筒将光收敛到一个方向形成的光束。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据距离。
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，网络设备通过不同的资源来测量不同的波束，终端反馈测得的资源质量，网络设备可以知道对应的波束的质量。在数据传输时，波束也可以通过其对应的资源指示。例如，网络设备通过下行控制信息(downlink control information，DCI)中的传输配置编号(transmission configuration index，TCI)字段指示一个传输配置指示-状态(state)，终端根据该TCI-状 态中包含的参考资源来确定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-状态等。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。
可以理解，本申请实施例统一采用波束进行表述，但波束可以替换理解为其他等同的概念，且不限于上述提到的概念。
2、资源：
在通信协议中，参考信号是以资源的形式进行配置的。网络设备会将各个参考信号以资源的形式配置给终端，一个资源即为一个配置信息单元，通常包括一个参考信号相关的参数，如参考信号的时频资源位置，端口数，时域类型(周期性/半静态/非周期)等等。
资源可以是上行信号资源，也可以是下行信号资源。上行信号包括但不限于探测参考信号(sounding reference signal，SRS)，解调参考信号(demodulation reference signal，DMRS)。下行信号包括但不限于：信道状态信息参考信号(channel state information reference signal，CSI-RS)、小区专用参考信号(cell specific reference signal，CS-RS)、UE专用参考信号(user equipment specific reference signal，US-RS)、解调参考信号(demodulation reference signal，DMRS)、以及同步信号/物理广播信道块(synchronization system/physical broadcast channel block，SS/PBCH block)。其中，SS/PBCH block可以简称为同步信号块(synchronization signal block，SSB)。
资源可以通过无线资源控制(radio resource control，RRC)消息配置。在配置结构上，一个资源是一个数据结构，包括其对应的上行/下行信号的相关参数。例如，上行/下行信号的类型、承载上行/下行信号的资源粒、上行/下行信号的发送时间和周期、发送上行/下行信号所采用的端口数等。每一个上行/下行信号的资源具有唯一的标识，以标识该下行信号的资源。可以理解的是，资源的标识也可以称为资源的标识，本申请实施例对此不作任何限制。
3、波束管理：
第五代(5th generation，5G)移动通信系统可以采用高频通信，即采用较高频段，如28吉赫兹(GHz)信号传输数据。高频通信的一个主要问题是信号能量随传输距离下降较快，导致信号传输距离短。为了克服这个问题，高频通信采用模拟波束技术，通过对天线阵列进行加权处理，将信号能量集中在一个较小的角度范围内，形成一个类似于光束一样的信号(称为模拟波束，简称波束)，从而提高传输距离。
网络设备和终端都要采用波束进行传输。在下行传输中，网络设备采用的波束称为下行发送波束，终端采用的波束称为下行接收波束。在上行传输中，终端采用的波束称为上行发送波束，网络设备采用的波束称为上行接收波束。在下行传输和上行传输中，网络设备和终端具体采用什么波束可以通过波束管理流程确定。
例如，网络设备有M个波束，终端有N个波束，下行波束管理过程如下：
1)波束管理配置：网络设备向终端发送配置消息，用以为终端配置下行波束管理相关的参数，如包括M个测量资源，测量周期等。测量资源可以为用于波束测量的参考信号(reference signal，RS)。M个测量资源与网络设备的M个波束一一对应，网络设备采用各个波束发送对应的测量资源，终端测量该测量资源即可确定该测量资源对应的波束的质量。可以理解，网络设备的波束对终端是不可见的，终端可以确定各个测量资源的质量，但该测量资源对应的是哪个波束，终端不感知。
2)波束测量：每个网络设备的波束与每个终端的波束对应的信道质量是不同的，终端需要测量每个网络设备的波束与每个终端的波束之间的信道质量，从而确定网络设备采用什么波束进行发送，终端采用什么波束进行接收是较佳的。具体的，在每个测量周期，网络设备采用上述M个波束依次发送对应的测量资源，终端采用N个波束中的一个进行接收和测量，以确定终端本次采用的波束与上述M个波束之间的信道质量，例如，参考信号接收功率(reference signal receiving power，RSRP)。在各个测量周期，终端依次采用不同的波束进行接收和测量，通过N个测量周期可以确定终端的N个波束与网络 设备的M个波束之间的信道质量。
3)测量结果上报：终端通过上述波束测量，可以根据信道质量，确定每个测量资源对应的终端最佳波束，或者说终端最佳接收波束或者最佳接收波束。终端可以将终端最佳波束对应的测量资源的信息上报给网络设备，以便网络设备确定网络设备采用什么波束进行发送，终端采用什么波束进行接收是较佳的。例如，如果网络设备采用某个测量资源对应的波束进行下行传输，终端会采用对应的最佳波束进行接收。其中，终端上报的测量资源的信息果可以包括至多4个终端最佳波束对应的测量资源的标识和RSRP。网络设备能够根据M个波束和M个测量资源的对应关系，确定终端上报的测量资源标识对应的网络设备的波束。例如，终端通过波束测量可以确定质量最好的4个测量资源为RS#1，RS#2，RS#3，RS#4，4个测量资源对应的终端最佳波束分别为波束B1，波束B2，波束B2，波束B3。也即，终端使用波束B1接收的4个测量资源中，RS#4的质量最好。终端使用波束B2接收的4个测量资源中，RS#2和RS#3的质量最好。终端使用波束B3接收的4个测量资源中，RS#1的质量最好。终端可以向网络设备上报RS#1，RS#1对应的RSRP1，RS#2，RS#2对应的RSRP2，RS#3，RS#3对应的RSRP3，RS#4，RS#4对应的RSRP4。
4)终端接收波束维护：终端向网络设备上报终端最佳波束对应的测量结果后，终端可以维护终端最佳波束与终端最佳波束对应的测量资源之间的映射关系。例如，映射关系可以如下表1所示。
表1
4、波束指示：
在下行传输中，网络设备采用的波束需要告知给终端，用以终端确定采用什么波束进行接收。具体的，网络设备可以向终端指示一个测量资源的标识，用于告知终端其采用了该测量资源对应的波束进行下行发送，这样终端可以采用该测量资源对应的终端最佳波束进行接收。例如，网络设备告知终端其采用的是RS#2对应的波束进行下行发送，终端采用波束B2进行下行接收。在上行传输中，终端采用的波束进行发送也是由网络设备指示的。具体的，网络设备可以向终端指示一个测量资源的标识，表示要求终端采用该测量资源对应的终端最佳波束进行上行传输。例如，网络设备向终端指示采用RS#2对应的波束进行上行传输，终端采用波束B2进行上行传输。
5、天线面板：
天线面板可以指网络设备的天线面板，也可以指终端的天线面板。一个天线面板上一般有一个或多个天线，这些天线排列成天线阵列，进行波束赋形，从而形成模拟波束。天线阵列可以生成指向不同方向的模拟波束。也就是说，每个天线面板上都可以形成多个模拟波束，可以通过波束测量来确定该天线面板采用哪个模拟波束是最好的。在本申请实施例中，若未做出特别说明，天线面板均指终端的天线面板。
在通信协议中，天线面板可以用面板(panel)、或者面板标识(panel index)等来表示，或者，也可以通过其他方式来隐含表示天线面板。例如，天线面板也可以通过天线端口(如CSI-RS端口、SRS端口、DMRS端口、相位追踪参考信号(phase-tracking reference signal，PTRS)端口、小区参考信号(cell-specific reference signal，CRS)端口、跟踪参考信号(tracking reference signal，TRS)端口、或SSB端口等)或天线端口组等来表征，也可以通过资源(如CSI-RS资源、SRS资源、DMRS资源、PTRS资源、CRS资源、TRS资源、SSB资源等)或资源组来表征，也可以通过某个信道表征(如物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink sharing channel，PUSCH)、物理随机接入信道(physical random access channel，PRACH)、PDSCH、物理下行控制信道(physical downlink control channel，PDCCH)、或物理广播信道(physical broadcast channel，PBCH)等)，也可以通过波束，如准同位(quasi-co-location，QCL)、TCI-状态、空间关系、或者配置在QCL、TCI-state、空间关系中的某个标识来表征，也可以通过波束组，如QCL组、TCI-状态组、或空间关系组等来表征，也可以通过终端上报的终端能力参数集合来表征(终端能力参数集合与天线面板存在对应关 系)。一个终端能力参数集合包括一个天线面板对应的相关终端能力。例如，包括一个天线面板对应的最大传输层数、最大SRS端口数、以及最大传输功率等。也就是说，本申请实施例中提到的天线面板也可以替换为上述内容。
终端可以配备多个天线面板。这些天线面板可以分布在不同的位置，朝向不同的方向，这可以保证不论终端朝向哪个方向，都至少有一个天线面板是朝向网络设备的，可以与网络设备进行数据传输。
图1为终端的多天线面板的结构示意图，如图1所示，终端配备了2个天线面板，每个天线面板朝向不同的方向，每个天线面板可以生成多个不同方向的波束，从而构成较为全面的波束覆盖。在现有通信协议中，终端的上行传输通常采用单个波束。单个波束的缺点是支持的传输流数低，传输功率受限，传输可靠性低，如单个波束被遮挡时传输会失败。为了克服上述问题，R18标准正在讨论如何实现上行波束同时发送，简称多波束同传，由于每个波束通过一个天线面板生成，因此多波束同传也可称为多天线面板同传。但是，在多天线面板的情况下，一个测量资源对应的终端的波束可以有多个，但目前的上报机制，即上报该测量资源的标识，使得网络设备无法确定该测量资源对应的终端的波束是一个还是多个，也即无法确定终端是否可以采用多天线面板同传，从而无法实现对终端的多天线面板同传进行有效调度。
6、最大允许辐射量(maximum permissible exposure，MPE)：
MPE是法规规定的人体可以接收的最大电磁辐射量。用于在适用终端时，会受到终端的电磁辐射，该电磁辐射主要来源于终端的发射信号。当终端的发射信号强度太高时，会对用于产生过高的电磁辐射，甚至超过法规允许的最大电磁辐射量。在这种情况下，终端需要降低其发射功率，即进行功率回退来减少对人体的电磁辐射，从而满足MPE法规要求。终端采用不同的波束朝不同的方向发射信号，不同波束对人体产生的辐射效果是不一样的，有的波束会对人体产生辐射，有的波束不会，有的波束产生的辐射较强，有的波束产生的辐射较弱，因此不同波束对应的终端发射功率回退量也不一样，有的波束需要功率回退，有的波束不需要功率回退，有的波束的终端发射功率回退量较大，有的波束的终端发射功率回退量较小。例如，终端可以通过终端的传感器感应各个波束方向上是否有人体，并确定各个波束方向对人体的辐射是否超标，以及在辐射超标的情况下，需要回退多少终端发射功率回退量。第三代合作伙伴计划(3rd generation partnership project，3GPP)标准中规定，终端为了满足MPE法规要求进行功率回退后，需要将终端最佳波束的终端发射功率回退量上报给网络设备，以便网络设备在选择终端的上行发送波束时进行参考。在3GPP标准中，出于上报开销的考虑，终端可以上报至多4个终端最佳波束的终端发射功率回退量。
图2为功率回退的场景示意图一，如图2所示，通过波束管理流程，终端上报RS#2和RS#4的RSRP分别为-80分贝毫瓦(decibel relative to one milliwatt，dBm)和-81dBm。由于RS#2的RSRP大于RS#4的RSRP，网络设备通常会指示终端采用RS#2对应的波束B2进行上行传输。但是，如果终端确定RS#2和RS#3对应的波束B2存在3dB的功率回退，则导致采用波束B2进行上行传输时信号质量，反而不如采用RS#4对应的波束B3进行上行传输时信号质量。因此，终端可以上报RS#2和RS#3对应的波束B2存在3dB的功率回退，如表2所示。
表2
此时，网络设备可以根据终端上报的RS#3和RS#2对应的波束B2存在3dB的功率回退，指示终端采用RS#4对应的波束B3进行上行传输。
但是，针对多波束同传场景，终端只上报终端最佳波束的终端发射功率回退量的方式可能导致上行传输性能损失。
图3为功率回退的场景示意图二，如图3所示，在多波束同场景下，终端通过2个天线面板分别发送波束B1和波束B2，且波束B1和波束B2都对着RS#3对应的网络设备的波束方向进行发送。波束B1是RS#3对应的终端最佳波束。如果波束B2发生终端发射功率回退，波束B1未发生终端发射功率回退，则因为波束B2不是RS#3对应的终端最佳波束，终端不会上报波束B2的终端发射功率回退量。此时，由于终端实际已经将波束B2的终端发射功率回退，波束B1和波束B2的上行传输性能降低，但 网络设备因为不知道波束B2的终端发射功率回退，仍调度波束B1和波束B2执行上行传输，导致上行传输性能不佳。
针对上述技术问题，本申请实施例提出如下技术方案，用以实现对多波束同传的有效调度的同时，还能够避免上行传输性能受到影响。

为便于理解本申请实施例，首先以图4中示出的通信系统为例详细说明适用于本申请实施例的通信系统。
图4为本申请实施例提供的波束测量方法所适用的一种通信系统的架构示意图一。如图4所示，该通信系统包括：终端和网络设备。
其中，终端可以为具有收发功能的终端，或为可设置于该终端的芯片或芯片系统。该终端也可以称为用户设备(uesr equipment，UE)、接入终端、用户单元(subscriber unit)、用户站、移动站(mobile station，MS)、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请的实施例中的终端可以是手机(mobile phone)、蜂窝电话(cellular phone)、智能电话(smart phone)、平板电脑(Pad)、无线数据卡、个人数字助理电脑(personal digital assistant，PDA)、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、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端、增强现实(augmented reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、车载终端、具有终端功能的路边单元(road side unit，RSU)等。本申请的终端还可以是作为一个或多个部件或者单元而内置于车辆的车载模块、车载模组、车载部件、车载芯片或者车载单元。或者，终端也可以是客户终端设备(customer-premises equipment，CPE)。
网络设备可以为接入网(access network，AN)设备，或可以称为无线接入网设备(radio access network，RAN)设备。RAN设备可以为终端提供接入功能，负责空口侧的无线资源管理、服务质量(quality of service，QoS)管理、数据压缩和加密等功能。RAN设备可以包括5G，如NR系统中的gNB，或，5G中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB、传输点(transmission and reception point，TRP或者transmission point，TP)或传输测量功能(transmission measurement function，TMF)的网络节点，如基带单元(building base band unit，BBU)，或，集中单元(centralized unit，CU) 或分布单元(distributed unit，DU)、具有基站功能的RSU，或者有线接入网关，或者5G的核心网网元。或者，RAN设备还可以包括无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)，无线中继节点、无线回传节点、各种形式的宏基站、微基站(也称为小站)、中继站、接入点、可穿戴设备、车载设备等等。或者，RAN设备可以也可以包括下一代移动通信系统，例如6G的接入网设备，例如6G基站，或者在下一代移动通信系统中，该网络设备也可以有其他命名方式，其均涵盖在本申请实施例的保护范围以内，本申请对此不做任何限定。
可以理解，图4为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备，和/或，其他终端设备，图4未予以画出。
图5本申请实施例提供的波束测量方法所适用的一种通信系统的架构示意图二。如图5示，该通信系统中网络设备和终端之间的通信还可以用另一种形式来表示。终端10包括：处理器101、存储器102和收发器103，收发器103包括：发射机1031、接收机1032和多个天线1033(天线面板)。网络设备20包括处理器201、存储器202和收发器203，收发器203包括：发射机2031、接收机2032和至少一个天线2033(天线面板)。发射机2031可以用于通过天线2033向终端10发送传输控制信息，如用于指示多天线面板频分同传的指示信息。相应的，接收机1032可以用于通过天线1033接收传输控制信息。如此，发射机1031可以用于通过多个天线1033(多个天线面板)，以频分同传的方式，向网络设备20发送传输反馈信息，也即上行数据。相应的，接收机2032可以用于通过天线2033接收终端10发送的传输反馈信息。

可选地，配置信息还用于指示测量资源集合，如果第一测量资源和第二测量资源为同一个资源，如测量资源集合中的第三测量资源，则终端还可以根据第一测量资源对应的终端的第一波束的发射功率回退量，以及第二测量资源对应的终端的第二波束的发射功率回退量，确定第三测量资源对应的终端发射功率回退量。如此，网络设备能够准确评估第三测量资源对应的两个波束的整体传输质量，从而对终端的上行传输进行调度，以避免上行传输性能受到影响。
方便理解，下面将结合图6本申请实施例提供的波束测量方法进行具体阐述。
示例性的，图6本申请实施例提供的波束测量方法的流程示意图。该方法可以适用于上述通信系统中网络设备与终端之间的通信。
如图6所示，该波束测量方法的流程如下：
S601，网络设备向终端发送配置信息，终端接收来自网络设备的配置信息。
配置信息可以用于指示终端向网络设备发送测量资源对的信息。该测量资源对可以包括两个测量资源，两个测量资源对应的终端的两个波束能同时用于上行传输。或者说，配置信息可以用于指示在波束测量过程中，终端需要向网络设备发送测量资源对的测量结果。测量资源对可以包括两个测量资源，终端接收这两个测量资源所使用的两个波束能用于终端同时执行上行传输。
具体的，配置信息可以包括波束管理相关的配置参数，记为第一配置参数。第一配置参数可以包括第一上报准则。第一上报准则可以默认用于指示：终端向网络设备发送测量资源对的信息，或者说在波束测量过程中，终端需要向网络设备发送测量资源对的测量结果，以及终端接收测量资源对所使用的两个波束能用于终端同时执行上行传输。也就是说，第一配置参数可以通过携带第一上报准则来指示终端执行多波束上行同传。如果第一配置参数中没有携带第一上报准则，则表示终端可以按照现有逻辑执行处理。或者，第一配置参数可以始终携带第一上报准则，第一上报准则的不同取值可以指示终端的不同行为。例如，第一上报准则为一个比特的信元，该比特的一种取值可以用于指示终端执行多波束上行同传；或者，该比特的另一种取值可以用于指示终端可以按照现有逻辑执行处理。
可以理解，第一上报准则为一种示例性的命名，也可以替换为其他任何可能的命名，如第一准则、第一规则、第一上报规则等。此外，本申请实施例提到的“同时”并不是指时间完全相同，即使时间存在一定的误差也可以认为是“同时”。
还可以理解，本申请实施例是以测量资源对为例，测量资源对也可以替换为多个测量资源，如2个 以上的测量资源。多个测量资源也可以理解为测量资源组、或者测量资源集合等，不做限定。多个测量资源对应的终端的多个波束能同时用于上行传输。也即，第一上报准则也可以默认用于指示：终端向网络设备发送多个测量资源的信息，以及终端接收这多个测量资源所使用的多个波束能用于终端同时执行上行传输。方便理解，下文是以2个测量资源，即测量资源对为例进行介绍。
配置信息可以用于指示终端向网络设备发送测量资源对的信息。该测量资源对可以包括两个测量资源，两个测量资源对应的终端的两个波束能同时用于上行传输。
配置信息还可以用于指示多个测量资源，或者说第一测量资源集合。这多个测量资源可以与网络设备的多个波束一一对应，也即，网络设备的每个波束都可以用于发送对应的一个测量资源，用以实现波束测量。
具体的，第一配置参数可以包括如下至少一项：多个测量资源的标识，测量周期，以及第一资源数量。测量周期可以用于指示网络设备具体可以在哪些周期性的时间点发送这多个测量资源，以便终端可以针对性地进行接收。第一资源数量可以用于指示终端至多能够上报测量资源的数量，如2、4、6等，不做限定。其中，终端上报测量资源可以是上报测量资源的标识，具体可以参考下述S602中的相关介绍，不再赘述。
S602，终端根据配置信息，向网络设备发送第一测量资源对的信息，网络设备接收来自终端的第一测量资源对的信息。
第一测量资源对可以包括第一测量资源和第二测量资源。第一测量资源和第二测量资源路可以是上述多个测量资源中的两个测量资源。第一测量资源和第二测量资源对应的终端的两个波束能同时用于上行传输。例如，第一测量资源是终端使用终端的第一波束接收的测量资源中，信号质量大于预设质量的测量资源，第二测量资源是终端使用终端的第二波束接收的测量资源中，信号质量大于质量阈值的测量资源，第一波束和第二波束能同时用于终端的上行传输。可以理解，由于第一测量资源和第二测量资源都可以是信号质量比较强的测量资源，网络设备通过调度第一测量资源和第二测量资源来指示终端执行上行同传，可以保障传输质量。
第一测量资源对的信息可以用于指示第一测量资源和第二测量资源的信号质量，如RSRP，或者其他任何可能被用于表征测量资源的信号质量的信息，不做限定。例如，第一测量资源对的信息可以包括如下至少一项：第一测量资源的参考信号接收功率RSRP、第二测量资源的标识，或第二测量资源的RSRP，用以准确指示第一测量资源和第二测量资源的质量。
具体的，网络设备可以根据配置信息，向终端发送多个测量资源。例如，网络设备可以根据测量周期，周期性地向终端发送多个测量资源。其中，网络设备可以使用网络设备的多个波束，发送这多个测量资源，也即，每个波束可以被用于发送该波束对应的一个测量资源。
终端可以根据配置信息，接收来自网络设备的多个测量资源。例如，终端可以包括第一天线面板和第二天线面板。终端可以使用第一天线面板接收多个测量资源。其中，第一天线面板的每个波束可以被用于接收多个测量资源中的至少部分测量资源，用以终端确定该波束接收的测量资源的信号质量。以第一天线面板的第一波束为例，终端可以使用第一波束接收多个测量资源，以确定第一波束接收的多个测量资源各自的质量。类似的，终端也可以使用第二天线面板接收多个测量资源。其中，第二天线面板的每个波束可以被用于接收多个测量资源中的至少部分测量资源，用以终端确定该波束接收的测量资源的质量。以第二天线面板的第二波束为例，终端可以使用第二波束接收多个测量资源，以确定第二波束接收的多个测量资源各自的信号质量。
方便理解，下面通过一个示例说明：
网络设备包括4个波束分别为波束A-波束D，4个波束对应的4分别为RS#1-RS#4。网络设备可以使用波束A发送RS#1，波束B发送RS#2，波束C发送RS#3，以及波束D发送RS#4。终端包括天线面板1和天线面板2，天线面板1包括波束B1和波束B2，天线面板2包括波束B3和波束B4。终端可以使用波束B1接收RS#1-RS#4，以确定RS#1的RSRP11，RS#2的RSRP12，RS#3的RSRP13，以及RS#4的RSRP14。终端可以使用波束B2接收RS#1-RS#4，以确定RS#1的RSRP21，RS#2的RSRP22，RS#3的RSRP23以及RS#4的RSRP24。终端可以使用波束B3接收RS#1-RS#4，以确定RS#1的RSRP31，RS#2的RSRP32，RS#3的RSRP33以及RS#4的RSRP34。终端可以使用波束B4接收RS#1-RS#4，以确定RS#1的RSRP41，RS#2的RSRP42，RS#3的RSRP43以及RS#4的RSRP44。
可以理解，终端可同时或分时使用终端的多个天线面板接收多个测量资源，不做限定。
终端可以根据配置信息，向网络设备发送多个测量资源中第一测量资源对的信息，相应的，网络设备可以接收来自终端的第一测量结果对的信息。也就是说，在波束测量过程中，网络设备可以不用指定终端具体上报哪两个资源，终端可以根据实际需求选择对应的两个测量资源进行上报，以满足实际需求。例如，终端可以上报平均信号质量最强的两个资源。
例如，终端可以根据接收的测量资源的信号质量，将多个天线面板的波束组合，组合的波束可以用于终端同时执行上行传输。以第一天线面板和第二天线面板为例，终端可以从使用第一天线面板的波束接收的测量资源中确定信号质量大于预设质量的测量资源，可以理解为最佳测量资源，从而确定这些最佳测量资源对应的终端最佳波束，如接收这些最佳测量资源使用的第一天线面板的波束的集合，记为第一波束集合。此时，第一测量资源可以是信号质量最好的测量资源，终端可以确定第一波束为终端最佳波束，也即，第一波束集合可以包括第一波束。类似的，终端可以从使用第二天线面板的波束接收的测量资源中的最佳测量资源，从而确定这些最佳测量资源对应的终端最佳波束，如接收这些最佳测量资源使用的第二天线面板的波束集合，记为第二波束集合。此时，第二测量资源可以是信号质量最好的测量资源，终端可以确定第二波束也为终端最佳波束，也即第二波束集合可以包括第二波束。第一波束集合中的一个波束可以与第二波束集合中的一个波束组合为一个波束对，该波束对包含的两个波束可以被用于终端同时执行上行传输。其中，第一波束集合中的波束与第二波束集合中的波束可以任意组合，或者也可以按照测量资源的信号质量从高到低或从低到高的顺序组合，不做限定。如此，终端可以确定至少一个波束对，并维护每个波束对与使用该波束对接收的两个最佳测量资源的映射关系，这两个最佳测量资源可以被称为测量资源对。至少一个波束对可以对应至少一个测量资源对。例如，第一波束和第二波束可以组成第一波束对，第一测量资源和第二测量资源可以组成第一测量资源对，用以终端同时执行上行传输。终端可以维护第一波束对与第一测量资源对的映射关系。
可以理解，一个测量资源对包含的两个测量资源可以是同一个测量资源，如第一测量资源与第二测量资源可以是同一个测量资源；或者，一个测量资源对包含的两个测量资源也可以是不同的测量资源，如第一测量资源与第二测量资源可以是不同的测量资源，不做限定。
还可以理解，如果是多个测量资源的情况，也即终端的多个波束能同时用于上行传输，则终端还可以维护这多个波束的对应关系。
方便理解，继续对上述示例进行说明：
针对天线面板1接收的RS#1-RS#4，终端确定RSRP11和RSRP12的质量最好，RSRP11对应波束B1，RSRP12对应的波束B2，也即第一波束集合包括波束B1和波束B2。针对天线面板2接收的RS#1-RS#4，终端确定RSRP31的质量最好，RSRP31对应波束B3，也即第二波束集合包括波束B3。终端可以将波束B1与波束B3组合为波束对1，波束B2与波束B3组合为波束对2。使用波束对1接收的两个最佳测量资源是同一个测量资源，也即RS#1，终端可以维护波束对1与RS#1的映射关系，具体如下表3所示。使用波束对2接收的两个最佳测量资源是不同的测量资源，也即RS#1和RS#2，终端可以维护RS#1和RS#2与波束对2的映射关系，具体如下表3所示。
表3
可以理解，波束对1与RS#1的映射关系，以及RS#1和RS#2与波束对2的映射关系，也可以通过不同的表项来分别维护，不做限定。
终端可以根据配置信息，如第一上报准则，向网络设备发送第一测量资源对的信息。相应的，网络设备接收来自终端的第一测量资源对的信息。
方便理解，继续对上述示例进行说明：
终端可以向网络设备发送测量资源对1的信息，包括：2个RS#1，以及RSRP11和RSRP31。以及，终端还可以向网络设备发送测量资源对2的信息，包括：RS#1和RS#2，以及RSRP11和RSRP12。
还可以理解，本申请实施例是以终端上报终端最佳波束对应的测量资源对为例，但不作为限定，例如，终端也可以上报终端的任意波束对应的测量资源对。此外，S602也可以理解为网络设备和终端根 据配置信息，执行波束测量，第一测量资源对的信息也可以理解为第一测量结果。
综上，终端可以根据配置信息的指示，向网络设备上报测量资源对，以便网络设备能够根据测量资源对，确定终端有两个波束能用于终端同时执行上行传输，也即，实现网络设备能够确定用于多个波束同发的波束，从而实现对多波束同传的有效调度。
可选地，结合上述实施例，本申请实施例提供的方法还可以包括如下步骤：
S603，网络设备向终端发送指示信息，终端接收来自网络设备的指示信息。
指示信息可以用于指示终端使用两个测量资源，如第一测量资源和第二测量资源对应的终端的两个波束，同时进行上行传输，或者说，指示信息可以用于指示终端使用指定的两个波束，如第一波束和第二波束同时执行上行传输。也就是说，终端是否采用多波束同传，可以由网络设备通过指示信息来灵活调度，以实现按需采用多波束同传。以第一波束和第二波束为例，指示信息可以包括第一测量资源的标识和第二测量资源的标识。例如，指示信息可以携带在两个TCI-状态或两个空间关系中，一个TCI-状态或空间关系可以包括第一测量资源的标识，另一个TCI-状态或空间关系可以包括第二测量资源的标识。
方便理解，继续对上述示例进行说明：网络设备可以向终端发送2个RS#1，用以指示终端需要使用波束B1和波束B3执行上行同传。
终端可以根据本地维护的映射关系，确定指示信息指示的两个测量资源属于同一个测量资源对，如第一测量资源和第二测量资源属于第一测量资源对，从而确定该测量资源对对应的两个波束，如第一波束和第二波束需要用于执行上行同传。如此，终端可以使用第一波束和第二波束，同时向网络设备发送上行信号，以实现上行同传。
可以理解，通过波束测量，终端可以维护测量资源对和波束的映射关系。这样，即使网络设备指示测量资源对，终端也可以确定对应的两个波束，从而可以降低指示开销。
还可以理解，S603为可选步骤，例如，网络设备可以不发送指示信息，终端可以默认使用两个波束执行上行同传。此外，在多个测量资源的情况下，指示信息也可以指示多个测量资源，以调度终端使用这多个测量资源对应的终端的多个波束，同时进行上行传输。
可选地，结合上述实施例，本申请实施例提供的方法还可以包括如下步骤：
S604，终端根据配置信息，确定测量资源集合中第三测量资源对应的终端发射功率回退量。
配置信息还用于指示测量资源集合，如第二测量资源集合，第二测量资源集合可以用于终端检测第二测量资源集合中测量资源对应的波束是否有终端发射功率回退。第二测量资源集合与第一测量资源集合可以相同，或者第二测量资源集合与第一测量资源集合也可以不同，如第二测量资源集合可以是第一测量资源集合的子集，如包括第一测量资源和第二测量资源的子集。
具体的，配置信息还可以包括终端发射功率回退上报的配置参数，记为第二配置参数。第二配置参数可以包括如下至少一项：第二测量资源集合中多个测量资源的标识、功率回退量量化步长、或第二资源数量。功率回退量量化步长可以用于指示终端以什么粒度来确定终端发射功率回退量。第二资源数量可以用于指示终端至多能够上报多少波束的终端发射功率回退量，如2、4、6等，不做限定。
终端可以根据配置信息，检测第二测量资源集合中测量资源对应的波束是否有终端发射功率回退。如果第二测量资源集合中测量资源对应的波束有终端发射功率回退，则终端可以向网络设备上报该终端发射功率回退。
具体的，以第二测量资源集合包括第一测量资源和第二测量资源为例。如果第一测量资源和第二测量资源是不同的测量资源，如第一测量资源的标识和第二测量资源的标识不同，则终端可以按照现有处理逻辑，向网络设备发送第一测量资源和/或第二测量资源对应的终端发射功率回退量，不再赘述。或者，如果第一测量资源和第二测量资源是同一个测量资源，记为第三测量资源，或者说第一测量资源的标识和第二测量资源的标识，第三测量资源的标识相同，则终端可以根据第一测量资源对应的终端的第一波束的发射功率回退量，以及第二测量资源对应的终端的第二波束的发射功率回退量，联合确定第三测量资源对应的终端发射功率回退量，或者说，终端可以根据第一波束和第二波束的终端发射功率回退量，确定第三测量资源对应的终端发射功率回退量。
例如，在第一波束和/或第二波束有终端发射功率回退的情况下，终端可以根据第一波束和第二波束在映射关系中关联到同一个测量资源，如第三测量资源，确定第一波束和/或第二波束的终端发射功 率回退需要被联合处理，如第一波束和/或第二波束的终端发射功率回退量需要平均到这两个波束，作为这两个波束的整体终端发射功率回退量，也即第三测量资源对应的终端发射功率回退量。
也就是说，在第一波束和第二波束对应同一个测量资源，如第三测量资源的情况下，网络设备通过该第三测量资源对应的一个波束发送的信号能够被第一波束和第二波束同时接收。因此，这两个波束应当被看做是一个整体，无论哪一个波束发生终端发射功率回退，都会影响这两个波束整体的上行传输性能。这种情况下，终端需要上报这两个波束的整体终端发射功率回退量，以确保网络设备能够准确评估这两个波束的整体传输质量。
方便理解，继续对上述示例进行说明：
终端可以确定波束B1有3dB的终端发射功率回退量，波束B3没有终端发射功率回退。终端可以根据波束B1和波束B3都关联到RS#1，确定波束B1和波束B 3的整体终端发射功率回退量，如波束B1和波束B 3的终端发射功率回退量可以是波束B1的终端发射功率回退量的一半，如为1.2dB，以向网络设备发送RS#1的终端发射功率回退量为1.2dB。
可以理解，上述是以终端发射功率回退上报的配置参数与波束管理相关的配置参数承载在同一配置信息为例，例如，终端发射功率回退上报的配置参数与波束管理相关的配置参数承载也可以分别承载在不同的配置信息中。此外，本申请实施例是以2个波束为例，2个波束也可以替换为多个波束，也即，如果终端的多个波束用于上行同传，则终端也可以联合这多个波束的终端发射功率回退量，确定测量资源对应的终端发射功率回退量。
S605，终端向网络设备发送第三测量资源对应的终端发射功率回退量，网络设备接收来自终端的第三测量资源对应的终端发射功率回退量。
终端可以向网络设备发送第三测量资源的标识，以及终端发射功率回退量，用以联合指示第三测量资源对应的终端发射功率回退量。网络设备可以根据终端上报的第三测量资源对应的终端发射功率回退量，及时调整终端的上行传输方式，如指示终端采用其他未发生终端发射功率回退的波束执行上行同传，以保障上行传输的效率和可靠性。
方便理解，继续对上述示例进行说明：
网络设备可以根据RS#1的终端发射功率回退量为1.2dB，向终端发送RS#2和RS#3，用以指示终端后续需要采用波束B2和波束B3执行上行同传，以保障上行传输的效率和可靠性。
还可以理解，S604-S605为可选步骤，例如，终端也可以不上报功率回退量。
