本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)***，并且也可用于各种无线通信***，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他***。术语“***”和“网络”常被可互换地使用。CDMA***可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA***可实现诸如全球移动通信***(Global System for Mobile Communication，GSM)之 类的无线电技术。OFDMA***可实现诸如超移动宽带(UltraMobileBroadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信***(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的***和无线电技术，也可用于其他***和无线电技术。然而，以下描述出于示例目的描述了NR***，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR***应用以外的应用。

请参见图1，图1示出本发明实施例可应用的一种无线通信***的框图。无线通信***包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本发明实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信***中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基 本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本发明实施例中仅以NR***中的基站为例，但是并不限定基站的具体类型。
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***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***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***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到网络侧设备12)的上行链路，或用于承载下行链路(Downlink，DL)传输(例如，从网络侧设备12到终端11)的下行链路，用于承载终端11到其他终端11之间传输的旁链路(sidelink，SL，或译为副链路，侧链路，边链路等)。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。
长期演进(Long Term Evolution，LTE)***支持SL，用于终端(User Equipment，UE)之间不通过网络设备直接进行数据传输。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格服务质量(Quality of Service，QoS)需求的高级V2X业务将通过新空口(New Radio，NR)sidelink支持。
UE通过物理旁链路控制信道(Physical Sidelink Control Channel,PSCCH)发送旁链路控制信息(Sidelink Control Information，SCI)，调度物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)的传输以发送数据。
sidelink传输主要分广播(broadcast)，组播(groupcast)，单播(unicast)几种传输形式：单播顾名思义就是一到一(one to one)的传输；组播为一到多(one to many)的传输；广播也是one to many的传输，但是广播并没有UE属于同一个组的概念。
相关技术的sidelink中，支持基于SL PSSCH解调参考信号(Demodulation Reference Signal，DMRS)进行参考信号接收功率(Reference Signal Received Power，RSRP)测量，可以作为参考功率用于计算路损，可用于SL开环功率控制、自主资源选择模式(mode 2)下判断资源是否被占用等。
层1(Layer 1，L1)RSRP为在PSCCH端口和/或PSSCH端口测量所得，层3(Layer 3，L3)RSRP为一段时间内，终端测量的L1 RSRP的加权。
其中，用于开环功率控制的RSRP为终端测量上报的L3 RSRP，用于功控的L3 RSRP为基于PSSCH端口测量或PSCCH端口测量的L1 RSRP的加权。用于mode 2下判断资源是否被占用为L1 RSRP的值，为基于PSCCH端口或PSSCH端口测量所得的L1 RSRP。高层配置是基于PSCCH端口还是基于PSSCH端口进行测量。
NR V2X定义了两种模式(mode)，一种是mode1，基站调度资源，一种是mode2，UE自己决定使用什么资源进行传输，此时资源信息可能来自基站的广播消息或者预配置。在mode 2资源分配模式下，发送终端需要进行检测 (sensing)，包括解调SCI，获取RSRP门限值，根据测量的RSRP值与获取的RSRP门限值进行比较，判断资源是否被占用。
相关技术中，SL上开环功率控制基于终端上报的L3 RSRP进行调整。RSRP基于PSSCHDMRS进行测量。PSSCH DMRS可以由SCI指示为单端口传输，还是两端口传输。在进行RSRP测量的时候，如果基于两端口传输DMRS，终端需要定义是基于其中某一个端口进行测量，或者基于两个端口进行测量。否则，发送端根据上报的结果，无法衡量接收端检测到的RSRP的水平，可能导致不同链路补偿后效果不平衡，***吞吐量性能变差。
在一段时间内，发送端可能某些时刻为单端口传输，某些时刻为两端口传输，接收终端计算L3 RSRP的时候，需要定义基于什么端口的测量结果进行加权，否则，发送端对接收端检测到的RSRP水平估计不准确，导致SL开环功控不准确，导致***中干扰协调不好，使得***吞吐量性能变差。
另外，mode 2资源分配下，高层配置SL L1 RSRP是基于PSCCHDMRS还是基于PSSCHDMRS进行测量。若基于PSSCH DMRS，如上所述，PSSCH DMRS可以为单端口或两端口配置，终端需要定义是基于其中某一个端口进行测量，或者基于两个端口进行测量，作为L1 RSRP的测量值，与指示的RSRP门限值进行对比，判断资源是否被排除。若不定义，发送终端无法衡量检测到的RSRP的水平，导致资源排除的结果不准确。可能干扰更严重的资源被预留，导致资源碰撞，造成***吞吐量下降。
综上所述，在进行RSRP测量的时候，如果基于两端口或两层传输DMRS，终端需要定义是基于其中某一个端口进行测量，或者基于两个端口进行测量。否则，发送端无法衡量接收端检测到的RSRP的水平，导致计算路损不准确，可能导致不同链路补偿后效果不平衡，或者是检测不准确导致资源选择发生碰撞，使得***吞吐量性能变差。
