Description

通信方法和通信装置
本申请要求于2019年09月20日提交中国专利局、申请号为201910893934.5、申请名称为“通信方法和通信装置”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
本申请涉及通信领域，并且更具体地，涉及一种通信方法和通信装置。
背景技术
设备到设备(device to device，D2D)技术是一种终端设备直连技术。当前，允许D2D通信复用蜂窝通信的上行资源，但这种方法不能利用全带宽或者必须等到有上行子帧调度时才进行D2D传输，导致频谱利用率较低。另外，由于进行资源复用的D2D用户和蜂窝用户根据各自测量的信道质量分别使用波束赋形(beamforming)技术，D2D通信的波束和蜂窝用户传输的波束不可避免的互相造成干扰。
发明内容
本申请提供一种通信方法和通信装置，在提高频谱利用率的同时，有利于减小或避免D2D通信对蜂窝通信干扰。
第一方面，提供了一种通信方法，该方法包括：网络设备确定第一目标波束，第一目标波束为第一设备在目标传输资源上向第二设备发送时使用的波束，目标传输资源为网络设备与第三设备之间传输时使用的时频资源；网络设备向第一设备发送第一波束指示信息，第一波束指示信息用于指示第一目标波束。
本申请中，第一设备为D2D通信的发端，第二设备为D2D通信的收端；第三设备与网络设备通过蜂窝网络进行通信，其可以是终端设备，或者终端设备中的芯片，或者终端设备中的电路或电路模块等。
所述目标传输资源可以是用于上行通信的时频资源，也可以是用于下行通信的时频资源。
本申请提供的通信方法，一方面允许D2D通信和蜂窝通信复用蜂窝通信的时频资源，另一方面，可以由网络设备配置D2D通信的波束。这样，既能提高频谱利用率，又有利于较小甚至避免D2D通信对蜂窝通信的干扰。
结合第一方面，在第一方面的某些实现方式中，第一目标波束对第三设备的干扰低于第一门限值，或者，第一目标波束对网络设备的干扰低于第二门限值。
第一目标波束对第三设备的干扰低于第一门限值是指，第三设备测量到的第一目标波束的波束质量低于第一门限值，也称为，第三设备测量到的第一目标波束的波束干扰低于第一门限值。在本申请中，由于第一目标波束针对第三设备而言，是对第三设备的干扰， 因而第一目标波束的波束质量越好，比如，波束的功率越大，则第一目标波束的波束干扰越大，对第三设备的干扰越大；第一目标波束的波束质量越差，比如，波束的功率越小，则第一目标波束的波束干扰越小，对第三设备的干扰越小。在本申请中，波束质量或波束干扰中的一项或多项都可以通过波束的功率来表征，比如，可以通过参考信号，比如波束参考信号或波束赋形的信道状态信息参考信号的接收功率来表征，比如承载参考信号的符号内的所有资源元素RE上接收到的信号功率的平均值来表征。波束质量或波束干扰中的一项或多项也可以通过其他方式来表征，比如现有技术中的一些方式，在此不予限定。
结合第一方面，在第一方面的某些实现方式中，该方法还包括：网络设备确定第二目标波束，第二目标波束为网络设备在目标传输资源上向第三设备发送时使用的波束，或者，第二目标波束为第三设备在目标传输资源上向网络设备发送时使用的波束。

即，在D2D通信复用蜂窝通信的上行时频资源的场景下，网络设备还需要将用于蜂窝通信的第二目标波束通知给第三设备，以使第三设备使用第二目标波束进行上行通信。

示例性的，可用波束可以是指波束质量大于一个预设门限值的波束，不可用波束可以是指波束质量不大于(即，小于或者等于)该预设门限值的波束。类似地，干扰波束可以是指波束干扰大于一个预设门限值的波束，非干扰波束可以是指波束干扰不大于该预设门限值的波束。上述用于判断是可用波束还是不可用波束的门限值和用于判断是干扰波束还是非干扰波束的门限值可以相等，也可以不等，本申请对此不作限定。
基于上述方案，网络设备可以调度第一设备复用蜂窝通信的下行时频资源。并且，第二设备和第三设备可以分别对第一设备发送的测量信号进行测量并分别上报波束测量报 告，网络设备可以基于D2D通信的可用和/或不可用波束以及通信的干扰波束和/或非干扰波束，为第二设备配置最终用于D2D通信的波束(即，第一目标波束)。这样一方面能够提高频谱利用率，另一方面能够减小或避免D2D通信对蜂窝通信造成的干扰。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于多种通信***，例如：长期演进(long term evolution，LTE)***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)、通用移动通信***(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信***、未来的第五代(5th generation，5G)***或新无线(new radio，NR)等。
本申请实施例中的第一设备、第二设备以及第三设备可以是终端设备，也可以是配置于终端设备中的芯片，还可以是终端设备中的电路或电路模块。终端设备可以指用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、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。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、路侧单元、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端设备等，本申请实施例对此并不 限定。
本申请实施例中的网络设备可以是任意一种具有无线收发功能的设备，也可以是配置于该设备中的芯片，还可以是该设备中的电路或电路模块。该设备包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WiFi)***中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等，还可以为5G，如，NR，***中的gNB，或，传输点(TRP或TP)，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或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、介质接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。本申请可以应用于多种应用场景，如D2D、中继(Relay)、无线网格网络(Mesh)、接入回传一体化(integrated access&backhaul，IAB)、车联网(vehicle to everything，V2X)、UE协作、高频传输、工业场景、机器人协作、物联网等场景。
需要说明的是，为使本领域技术人员更好的理解本申请，下文中将以第一设备、第二设备和第三设备为UE、网络设备为基站为例，对本申请进行介绍。但应理解，UE可以被替换为其他形式的终端设备(或终端设备中的芯片或电路)，如车载设备、可穿戴设备等，类似地，基站也可以被替换为其他形式的网络设备，如gNB、eNodeB、eNodeB中芯片或电路等。
图1是应用于本申请的一个通信***的示意图。如图1所示，该通信***包括至少一个基站(如，基站110)和多个UE(如，UE120、UE130和UE140)。多个UE至少包括两个可以用于D2D通信的UE(如，UE120和UE130)和至少一个可以用于蜂窝通信的UE(如，UE140)。
其中，D2D通信是指两个UE之间通过侧行链路(sidelink)或PC5口直接进行的通信。进行D2D通信的UE在下文中称为D2D UE，其中作为发送端的D2D UE为第一设备，在下文中称为D2D发端UE，作为接收端的D2D UE为第二设备，在下文中称为D2D收 端UE。D2D UE也可以具有蜂窝通信功能，若存在与基站之间的通信需求时，D2D UE也可以进行蜂窝通信。
蜂窝通信是指UE和基站之间通过下行(downlink)或上行(uplink)进行的通信。进行蜂窝通信的UE为第三设备，在本文中称为蜂窝UE，蜂窝UE具有与基站进行蜂窝下行或上行通信的功能。蜂窝UE也可以具有D2D通信功能，若存在与其它D2D UE之间的通信需求时，蜂窝UE也可以与其它D2D UE进行D2D通信。
当前，D2D发端UE复用蜂窝通信的上行资源向D2D收端UE发送时，只能利用频分复用(frequency division duplex，FDD)***上行链路或者时分复用(frequency division duplex，TDD)上行子帧，不能利用全带宽或者必须等到有上行子帧调度时才进行D2D传输，导致频谱利用率较低。
另外，由于D2D UE间的信道状态信息(channel state information，CSI)仅能由D2D收端UE根据对D2D发端UE发送的测量信号测量获得，基站不可获得D2D UE间的信道状态信息，只能获得其与蜂窝UE之间的信道状态信息，进行资源复用的D2D UE和蜂窝UE根据各自测量的信道质量分别使用波束赋形技术，D2D通信的波束和蜂窝通信的波束不可避免的互相造成干扰。
为解上述问题，本申请提供了一种通信方法，一方面既允许D2D通信和蜂窝通信复用蜂窝通信上行资源，也允许D2D通信和蜂窝通信复用蜂窝通信下行资源，另一方面，可以由基站配置D2D通信的波束。这样，既能提高频谱利用率，又有利于减小甚至避免D2D通信对蜂窝通信的干扰和/或蜂窝通信对D2D通信的干扰。比如，基站可以将可用于D2D通信且不会对蜂窝UE造成干扰的波束配置给D2D发端UE，这样D2D发端UE在使用基站配置的波束发送时，既能够保证D2D收端UE的接收成功率，又能避免对蜂窝UE造成干扰。
本申请实施例中，波束(beam)可以理解为空间资源，或者，可以指具有能量传输指向性的发送或接收预编码向量，并且，该发送或接收预编码向量能够通过索引信息进行标识。其中，所述能量传输指向性可以指在一定空间位置内，接收经过该预编码向量进行预编码处理后的信号具有较好的接收功率，如满足接收解调信噪比等；所述能量传输指向性也可以指通过该预编码向量接收来自不同空间位置发送的相同信号具有不同的接收功率。
可选地，同一通信设备(比如终端设备或网络设备)可以有不同的预编码向量，不同的设备也可以有不同的预编码向量，即对应不同的波束。
针对通信设备的配置或者能力，一个通信设备在同一时刻可以使用多个不同的预编码向量中的一个或者多个，即同时可以形成一个或多个波束。波束相同，可以指波束的信息相同，或者，可以指具有相同的空间资源。在某些描述中，波束相同还可以覆盖具有准共址(QCL)关系或具有空间参考关系的资源。波束的信息可以通过索引信息进行标识。可选地，所述索引信息可以对应配置终端设备(如用户设备UE)的资源标识(identity，ID)，比如，所述索引信息可以对应配置的信道状态信息参考信号(channel state information reference signal，CSI-RS)的ID或者资源，也可以对应配置的上行探测参考信号(sounding reference signal，SRS)的ID或者资源。或者，可选地，所述索引信息可以是通过波束承载的信号或信道显示或隐式承载的索引信息，比如，所述索引信息可以是通过波束发送的同步信号或者广播信道指示该波束的索引信息。具体波束的信息如何指示在本申请实施例 中不予限定。
下面，对本申请提供的方案进行详细描述。
图2是本申请提供的一个通信方法的示意性流程图。如图2所示，该方法200包括S210和S220。以下，对各步骤进行详细说明。
S210，基站确定第一目标波束。
第一目标波束为D2D发端UE在目标传输资源上对D2D收端UE发送时使用的波束，目标传输资源为基站与蜂窝UE传输时使用的时频资源。也就是说，第一目标波束是基站给D2D发端UE配置的在D2D发端UE复用蜂窝通信的时频资源进行D2D通信时，使用的波束。其中，目标传输资源可以是上行时频资源(简称：上行资源)，也可以是下行时频资源(简称：下行资源)。也就是说，D2D通信可以使用蜂窝通信的上行资源，即，蜂窝UE向基站发送时使用的时频资源；D2D通信也可以使用蜂窝通信的下行资源，即，基站向蜂窝UE发送时使用的时频资源。
应理解，本文中将时分双工传输方式用到的下行子帧/时隙/符号和频分双工传输方式用到的下行频域资源中的一项或多项均可统称为下行资源。类似地，将时分双工传输用到的上行子帧/时隙/符号和频分双工传输方式用到的上行频域资源中的一项或多项均可统称为上行资源。
S220，基站向D2D发端UE发送第一波束指示信息，第一波束指示信息用于指示第一目标波束。第一目标波束包括一个或多个波束。
相应地，D2D发端UE接收第一波束指示信息，并且可以根据第一波束指示信息，确定第一目标波束。之后，D2D发端UE就可以在目标传输资源上使用第一目标波束对D2D收端UE进行发送。
本申请提供的通信方法，一方面既允许D2D通信复用蜂窝通信上行资源，也允许D2D通信复用蜂窝通信下行资源，另一方面，可以由基站配置D2D通信的波束。这样，既能提高频谱利用率，又有利于较小甚至避免D2D通信对蜂窝通信的干扰。
以下将结合图3至图8，对图2所示的方法进行详细说明。
图3是本申请提供的一个通信方法的示意图。该方法可以应用于D2D通信和蜂窝通信复用蜂窝通信的下行资源的场景。
参见图3，在该方法中，D2D发端UE发送测量信号，D2D收端UE通过对该测量信号进行测量，可以获得D2D通信的可用波束信息和/或不可用波束信息，并且将所获得的波束信息上报给基站。蜂窝UE通过对该测量信号进行测量，可以获得干扰波束信息和/或非干扰波束信息，并且将所获得的波束信息上报给基站。基站可以根据D2D收端UE和蜂窝UE上报的波束信息，确定第一目标波束。
下面，结合图4所示的通信方法300对此进行详细描述。
图4是本申请提供的通信方法300的示例性流程图。以下对图4所示的各步骤进行说明。
S301，基站向蜂窝UE配置下行资源(即，目标传输资源的一例)，并调度D2D发端UE在该下行资源上进行D2D发送。
比如，基站可以向蜂窝UE发送第一配置信息，并向D2D发端UE发送第二配置信息。相应地，蜂窝UE接收第一配置信息，D2D发端UE接收第二配置信息。其中，第一配置 信息用于向蜂窝UE配置该下行资源，第二配置信息用于向D2D发端UE配置该下行资源。
接下来，基站可以配置测量信号的发送资源、测量信号的检测资源、波束测量报告的上报资源以及上报参数。具体参见S302至S304。应理解，本申请并不限定配置测量信号的发送资源、测量信号的检测资源、波束测量报告的上报资源以及上报参数的顺序，也不限定配置同一类型的参数(比如，测量信号的检测资源)时，D2D收端UE和蜂窝UE的配置先后顺序。所述配置可以通过一条消息，或，多于一条消息实现。
S302，基站向D2D发端UE配置第一测量信号的发送资源。
比如，基站可以向D2D发端UE发送第一指示信息，第一指示信息可以指示第一测量的发送资源。
本申请中的测量信号(如，第一测量信号、下文中的第二测量信号、第三测量信号等)可以是波束参考信号(beam reference signal，BRS)或波束赋形的(beamformed)信道状态信息参考信号(channel state information reference signal，CSI-RS)，也可以是其它类型的测量信号，本申请对测量信号的类型不进行限定。
本领域技术人员可以理解，第一指示信息可以指示多个测量信号资源，比如，第一指示信息可以是多个CSI-RS资源指示(CSI-RS resource indicator，CRI)，每个CRI可以指示一个CSI-RS resource。D2D发端UE发送第一测量信号实际上是指D2D发端UE根据这多个测量信号资源，发送测量信号。应理解，一个测量信号资源可以认为是一个波束，用于指示测量信号资源的信息(比如测量信号资源的索引)也可以认为是该测量信号资源所代表的波束的信息。或者，用于指示测量信号资源的信息也可以与该测量信号资源所代表的波束的信息，比如同步信号块索引(SSB index)具有对应关系。其中，同步信号块可以包括主同步信号，辅同步信号和物理广播信道。
S303，基站向D2D收端UE和蜂窝UE配置第一测量信号的检测资源、测量报告的上报资源以及上报参数。
(1)基站配置第一测量信号的检测资源
示例性的，基站可以向D2D收端UE和蜂窝UE发送第二指示信息，第二指示信息指示第一测量信号的检测资源，第一测量信号的检测资源用于D2D收端UE和蜂窝UE对D2D发端UE发送的第一测量信号进行测量。
应理解，第二指示信息与第一指示信息相同，比如，第一指示信息为多个CRI，那么，第二指示信息也是该多个CRI。
(2)基站配置测量报告的上报资源
比如，基站可以向D2D收端UE发送第一上报资源信息，向蜂窝UE发送第二上报资源信息。其中，第一上报资源信息指示第一上报资源，D2D收端UE可以在第一上报资源上，向基站上报对第一测量信号进行测量得到的波束测量报告。第二上报资源信息指示第二上报资源，蜂窝UE可以在第二上报资源上，向基站上报对第一测量信号进行测量得到的波束测量报告。
本申请中，测量信号的发送资源、测量信号的检测资源和测量报告的上报资源中的任一种，都可以由基站通过下行控制信道中的下行控制信息(downlink control information，DCI)、下行数据信道、无线资源控制信令(radio resource control，RRC)、以及媒体接入控制控制单元(media access control control element，MAC CE)中的一项或多项配置。 应理解，这里的测量信号是一个统称，其可以是第一测量信号，也可以是下文中的第二测量信号、第三测量信号等。另外，所述下行控制信道例如可以是物理下行控制信道(physical downlink control channel，PDCCH)或增强物理下行控制信道(enhanced physical downlink control channel，EPDCCH)或其他类型的下行控制信道。所述下行数据信道例如可以是物理下行数据共享信道(physical downlink shared channel，PDSCH)或其他类型的下行数据信道。
需要说明的是，本申请中，测量信号(如第一测量信号、第二测量信号等测量信号)的发送资源、测量信号的检测资源和测量报告的上报资源中的任一种，也可以由相应的UE从资源池中自行确定，而不必由基站配置。比如，第一测量信号的发送资源可以由D2D发端UE从资源池中确定。资源池可以是预配置的，也可以由基站以广播的形式发送给UE。
还需要说明的是，本申请中，需要由基站发送给D2D收端UE的相关信息，如第一指示信息、第二指示信息等中的一项或多项，可以由基站直接发送给D2D收端UE，也可以由基站先发送给D2D发端UE，再由D2D发端UE转发给D2D收端UE。相应地，需要由D2D收端UE发送给基站的相关信息，如下文中的D2D收端UE发送的波束测量报告，可以由D2D收端UE直接发送给基站，也可以由D2D收端UE先发送给D2D发端UE，再由D2D发端UE转发给基站。
(3)基站配置上报参数
比如，基站可以向D2D收端UE发送第一上报参数信息，向蜂窝UE发送第二上报参数信息。其中，第一上报参数信息用于D2D收端UE确定对第一测量信号进行测量后所需要上报的内容。第二上报参数信息用于蜂窝UE确定对第一测量信号进行测量后所需要上报的内容。
第一上报参数信息可以包括下述中的一项或多项：波束属性信息；波束质量门限值；波束数量或者波束最大数量。
其中，波束属性信息用于指示D2D收端UE需要上报波束质量较好的波束，还是需要上报波束质量较差的波束，还是两者都要上报。D2D收端UE根据该波束属性信息，可以确定自己需要上报波束质量较好的波束，还是需要上报波束质量较差的波束，还是两者都要上报。示例性的，终端设备上报波束具体可以是终端设备上报CRI。
波束质量可以通过参考信号接收功率(reference signal receiving power，RSRP)、参考信号接收质量(reference signal receiving quality，RSRQ)等参数中的一项或多项衡量。相应地，波束质量门限值可以是RSRP、RSRQ等门限值中的一个或多个。D2D收端UE根据波束属性信息，上报对应的波束质量(例如RSRP或RSRQ)大于波束质量门限值的波束，或者，上报对应的波束质量不大于波束质量门限值的波束。或者，前述两者都上报，并指明每个波束具体是波束质量大于波束质量门限值的波束还是波束质量不大于波束质量门限值的波束。
波束数量是指，D2D收端UE需要反馈的波束质量较好的波束的数量，或者需要反馈的波束质量较差的波束的数量，或者需要反馈的波束质量较好的波束的数量以及波束质量较差的波束的数量。示例性的，假设这里的波束数量为N，那么，如果基站指示D2D收端UE反馈波束质量较好的波束，则D2D收端UE反馈波束质量最好的N个波束；如果 基站指示D2D收端UE反馈波束质量较差的波束，则D2D收端UE反馈波束质量最差的N个波束。示例性的，假设这里的波束数量为(P,Q)，那么，D2D收端UE反馈波束质量最好的P个波束以及波束质量最差的Q个波束。
波束最大数量是指，允许D2D收端UE反馈的波束的最大数量。比如，基站指示D2D收端UE反馈波束质量较好的波束，且波束最大数量为M，则D2D收端UE最多只能反馈波束质量较好的M个波束。
这里，对于D2D收端UE来讲，对应的波束质量大于波束质量门限值的波束，以及D2D收端UE基于波束数量或者波束最大数量反馈的波束质量最好的一个或多个波束，都可以称为：可用波束。
相应地，对应的波束质量不大于波束质量门限值的波束，以及D2D收端UE基于波束数量或者波束最大数量反馈的波束质量最差的一个或多个波束，都可以称为：不可用波束。
应理解，第一上报参数信息可以仅包括波束属性信息、波束质量门限值、以及波束数量(或波束最大数量)这三者中的其中两个。比如，第一上报参数信息可以仅包括波束属性信息和波束数量(或波束最大数量)，此时D2D收端UE根据波束属性信息的指示，上报要求数量的对应的波束质量最大或者最小的波束。再如，第一上报参数信息可以仅包括波束属性信息和波束质量门限值，此时D2D收端UE根据波束属性信息的指示，上报对应的波束质量大于或者不大于波束质量门限值的波束。
第二上报参数信息与第一上报参数信息所包括的内容类似。第二上报参数信息可以包括下述中的一项或多项：波束属性信息；波束干扰门限值；波束数量或者波束最大数量。
波束属性信息的含义与第一上报参数信息中的波束属性信息的含义类似，具体可以参照上文描述。
相应地，波束干扰门限值可以是RSRP、RSRQ等门限值中的一个或多个。D2D收端UE根据波束属性信息，上报对应的波束干扰(例如RSRP或RSRQ)大于波束干扰门限值的波束，或者，上报对应的波束干扰不大于波束干扰门限值的波束。或者前述两者都上报，并指明每个波束具体是波束干扰大于波束干扰门限值的波束还是波束干扰不大于波束干扰门限值的波束。波束干扰门限值可以和波速质量门限值相等，也可以不等，本申请对此不作限定。
波束数量的含义与第一上报参数信息中的波束数量的含义类似，具体可以参照上文描述。波束最大数量的含义也类似，可以参照上文描述。
这里，对于蜂窝UE来讲，对应的波束干扰大于波束干扰门限值的波束，以及蜂窝UE基于波束数量或者波束最大数量反馈的波束干扰最大的一个或多个波束，都可以称为：干扰波束。
相应地，对应的波束干扰不大于波束干扰门限值的波束，以及蜂窝UE基于波束数量或者波束最大数量反馈的波束干扰最小的一个或多个波束，都可以称为：非干扰波束。
需要说明的是，基站和D2D收端UE、蜂窝UE也可以预先约定上报参数信息(比如，第一上报参数信息、第二上报参数信息、下文中的第三上报参数信息等)所包括的内容中的一项或多项。比如，基站可以和D2D收端UE约定波束质量门限值、和蜂窝UE预先约定波束干扰门限值。再如，基站可以和D2D收端UE以及蜂窝UE预先约定波束数量或者 波束最大数量。
本申请中，上报参数信息(比如，上报参数信息#1、上报参数信息#2、下文中的上报参数信息#3等)可通过信号状态信息参考信号(channel state information reference signal，CSI-RS)报告配置(Reporting Settings)发送，也可采用其它方式发送，如可通过RRC信令发送，本申请对此不作限定。
需要说明的是，上报参数信息中的内容也可以通过多条信令分别进行通知。例如，第一上报参数信息中的波束属性信息可以由CSI-RS报告配置携带，波束质量门限值由RRC信令携带，反之亦可，本申请实施例对此不进行限定。
接着，D2D发端UE发送第一测量信号，D2D收端UE和蜂窝UE测量第一测量信号，并上报波束测量报告。基站根据D2D收端UE和蜂窝UE上报的波束测量报告，可以确定第一目标波束。具体参见S304至S306。
S304，D2D发端UE在第一测量信号的发送资源上发送第一测量信号。
D2D收端UE和蜂窝UE在第一测量信号的检测资源上测量第一测量信号。D2D收端UE对第一测量信号进行测量，并基于第一上报参数信息，可以确定第一波束测量报告。蜂窝UE通过对第一测量信号进行测量，并基于第二上报参数信息，可以确定第二波束测量报告。
其中，第一波束测量报告包括可用波束信息和/或不可用波束信息。比如，第一波束测量报告包括可用波束信息和不可用波束信息，或者可以仅包括可用波束信息和不可用波束信息中的其中一者。其中，可用波束信息用于指示可用波束，不可用波束信息用于指示不可用波束。第二波束测量报告包括干扰波束信息和/或非干扰波束信息。其中，干扰波束信息用于指示干扰波束，非干扰波束用于指示非干扰波束。
