Description

通信方法及装置

技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
动态(dynamic)时分双工(time division duplex，TDD)，亦可称为灵活双工(flexible duplexing)或双工灵活性(duplexing flexibility)，是指能够根据上下行业务的分布自适应地分配上下行资源，进而有效提高系统资源利用率。
通常，动态TDD存在交叉链路干扰(cross-link interference，CLI)问题。交叉链路干扰也可以称之为异向链路干扰，即不同方向的链路之间的干扰。如图1a所示，一方面，第二网络设备下的第二终端或第三终端的上行发送会对第一网络设备下的第一终端的下行接收造成CLI，这种CLI可称为终端之间(UE-to-UE)的干扰；另一方面，第一网络设备的下行发送会对第二网络设备的上行接收产生CLI，这种CLI可称为基站到基站(gNB-to-gNB)的干扰。
参见图1b，在一个具有多个网络设备的超密集组网中，不同的网络设备之间可能有无线回传(backhaul),当网络设备与终端设备之间的接入链路和网络设备之间的回传链路共存时，也会发生上述CLI。
动态的CLI不同以往的同链路干扰，它具有干扰严重且影响大、方向变化快、并且没有成熟机制来解决等特点。因此，亟待提出一种使得系统获知交叉链路干扰程度的方法。
发明内容
本申请实施例提供一种通信方法及装置，能够测量交叉链路干扰程度。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种通信方法，该方法可以由第一终端执行，或者，由第一终端中的组件(比如芯片系统)执行。该方法包括：第一终端接收至少一个第二终端发送的至少一个第一探测参考信号(sounding reference signal，SRS)，并根据至少一个第一SRS，获得至少一个第二终端的测量结果的信息，向网络设备发送一个或多个测量结果的信息。其中，测量结果用于表征第二终端发送的第一SRS的信号强度；第一SRS用于检测交叉链路干扰CLI，第一SRS占用第一资源。
本申请提供的通信方法可以应用于存在CLI的通信系统中。比如，上述提及的灵活双工系统，或者，综合接入和回传系统(integrated access and backhaul system，IAB)。还可以应用在远程干扰管理(remote interference management，RIM)系统中。比如，可应用于图1a和图1b所示的通信系统中。
本申请实施例提供的通信方法，某一第二终端发送第一SRS之后，若第一终端可以监听到该第二终端的第一SRS，则第一终端可以测量该第一SRS的信号强度，进而 得到该第一SRS的测量结果。并且，第一终端还可以将测量结果上报至网络设备，使得网络设备能够获取到不同第二终端的测量结果。如此，在后续，网络设备可以基于一个或多个测量结果获知不同第二终端对第一终端的CLI程度，并执行一些降低CLI的操作。
此外，网络设备在不获取测量结果的情况下，可以根据测量结果对应的第二指示信息获知对第一终端产生干扰的具体是哪些第二终端。比如，第一终端测量某一第一SRS，并向网络设备反馈该第一SRS的第二指示信息，包括但不限于该第一SRS序列，或者该第一SRS序列集合，或者，该第一SRS的资源标识中的至少一个时，网络设备能够确定该第一SRS的发送端。比如，第一终端测量某一第一SRS，并向网络设备反馈该第一SRS的资源标识，由此，网络设备可以知道使用该资源发送第一SRS的第二终端是哪一终端，进而网络设备可确定对第一终端产生CLI的干扰源。
在一种可能的设计中，所述一个或多个测量结果的信息包含所述一个或多个测量结果的指示信息，和/或第二指示信息，所述第二指示信息为所述一个或多个测量结果分别对应的第二终端的指示信息。
在一种可能的设计中，上述方法还包括：第一终端获得第一指示信息，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中最大的N个测量结果，或者最小的N个测量结果，N为大于或等于1的整数。
相应的，第一终端向网络设备发送一个或多个测量结果包括：第一终端根据第一指示信息，向网络设备发送N个测量结果。
在一种可能的设计中，上述方法还包括：第一终端获得第一指示信息，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中最大的N个测量结果分别对应的第二指示信息，或者最小的N个测量结果分别对应的第二指示信息，N为大于或等于1的整数。
其中，第二指示信息用于指示测量结果对应的第二终端。
相应的，第一终端向网络设备发送一个或多个测量结果的信息，包括：第一终端根据第一指示信息，向网络设备发送N个测量结果分别对应的第二指示信息。
在一种可能的设计中，上述方法还包括：第一终端获得第一指示信息，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中最大的N个测量结果，以及最大的N个测量结果分别对应的第二指示信息。N为大于或等于1的整数。
相应的，第一终端向网络设备发送一个或多个测量结果的信息，包括：第一终端根据第一指示信息，向网络设备发送N个测量结果，以及发送这N个测量结果分别对应的第二指示信息。
在一种可能的设计中，上述方法还包括：第一终端获得第一指示信息，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中最小的N个测量结果，以及最小的N个测量结果分别对应的第二指示信息。N为大于或等于1的整数。
相应的，第一终端向网络设备发送一个或多个测量结果的信息，包括：第一终端根据第一指示信息，向网络设备发送最小的N个测量结果，以及发送这N个测量结果分别对应的第二指示信息。
如此，由于当某一第二终端的测量结果越大时，该第二终端对第一终端的CLI程 度通常越强。网络设备基于CLI程度最强的测量结果就可以大致获知第一终端和其他终端之间的CLI情况，以便于执行一些降低CLI的操作，以降低第一终端和其他终端之间的CLI。可见，仅上报部分测量结果，使得上报测量结果的信令开销有所降低。
在一种可能的设计中，上述方法还包括：第一终端获得第一指示信息，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中大于或等于第一门限值的J个测量结果，和/或，发送所述J个测量结果分别对应的第二指示信息，J为正整数。

如此，仅上报部分测量结果，能够降低上报测量结果的信令开销。
在一种可能的设计中，上述方法还包括：第一终端获得第一指示信息，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中小于或等于第二门限值的W个测量结果，和/或，发送所述W个测量结果分别对应的第二指示信息，W为正整数。
相应的，第一终端向网络设备发送一个或多个测量结果的信息包括：第一终端根据第一指示信息，向网络设备发送至少一个第二终端的测量结果中小或等于第二门限值的W个测量结果，和/或，发送所述W个测量结果分别对应的第二指示信息。

也就是说，当第二次测量结果与第一次测量结果的差异较大，第一终端才会上报针对同一第二终端的第二次测量结果。采用上述方法，针对同一第二终端可以测量多次第一SRS，可提升该第二终端的第一SRS的测量结果的准确性。进一步的，数值相近的测量结果通常说明第二终端的位置、信号质量等未发生变化，或者变化不大，此种情况下，获取道第二终端的第一SRS的测量结果可能是冗余信息，网络设备可能并不需要该冗余信息来进行决策。因此，在本申请实施例中，第一终端仅上报与第一次测量结果相差较大的第二次测量结果，如此，能够避免第一终端上报数值相近的冗余测量结果，降低了信令开销。
在一种可能的设计中，方法还包括：第一终端获取配置信息，配置信息用于指示下述至少一项：

在一种可能的设计中，方法还包括：第一终端上报第三能力信息，第三能力信息用于指示第二资源与传输第一SRS的第一资源之间的复用关系，复用关系包括时分复用和频分复用中的至少一种，第二资源为用于数据传输的资源。

本申请实施例提供的通信方法可以应用于存在CLI的通信系统中。比如，上述提及的灵活双工系统，或者，综合接入和回传系统(integrated access and backhaul system，IAB)。还可以应用在远程干扰管理(remote interference management，RIM)系统中。参见图1a，为本申请实施例所适用的一种通信系统的示例性架构。该通信系统包括网络设备和终端设备。其中，图1a示例性的示出了三个终端设备(即UE1至UE3)和两个网络设备(即基站1和基站2)。上述终端设备可以通过空口连接到网络设备，以便接收网络服务。上述网络设备主要用于实现无线物理层功能、资源调度和无线资源管理、无线接入控制、移动性管理功能，或者其他功能。本申请中第一终端，第二终端或第三终端中的任何一个都可以替换为网络设备，即第一网络设备，第二网络设备或第三网络设备。本申请的第一终端，第二终端或第三终端分别为终端设备。
本申请中所述“获得”包含：预配置在终端/网络设备中，或者，由网络设备配置给终端。本申请中所述“配置”或“被配置”可以是网络设备通过信令配置给终端，其中信令可以是RRC信令，MAC信令或物理层信令中至少一种。
其中，上述网络设备可以指具有无线收发功能的设备，也可以指设置于该设备中的芯片系统，或其他形态。该网络设备包括但不限于：Wi-Fi系统中的接入点(access point，AP)，如家用无线路由器、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)，eNB、宏基站、微基站、高频基站、新型无线电基站(New radio 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)，还可以为5G系统，如NR中的gNB，或，传输点(TRP或TP)，5G系统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。

其中，存储器203用于存储用于实现本申请方案的计算机执行指令，并由处理器201来控制执行。处理器201用于执行存储器203中存储的计算机执行指令，从而实现本申请下述实施例提供的各个方法。

在具体实现中，作为一种实施例，处理器201可以包括一个或多个CPU，例如图2中的CPU0和CPU1。

以下结合图1a和图1b所示的通信系统，说明本申请实施例提供的通信方法。下文主要以网络设备为基站为例进行说明，在此统一声明，下文不再赘述。
参见图3，本申请实施例提供的通信方法包括如下步骤：
S301、第二终端向第一终端发送第一SRS。
相应的，第一终端接收至少一个第二终端发送的至少一个SRS。其中，第一SRS用于检测CLI，第一SRS占用第一资源。
在本申请实施例中，第一终端通常指可能被干扰的终端，在本文中，第一终端也可称为被干扰(interfered)终端。第二终端指可能对第一终端产生CLI的终端，在本文中，第二终端也可称为干扰(interfering)终端。在不同的通信场景中，第一终端和第二终端的角色可能互换。比如，在图1a中，UE2和UE3进行上行发送，此时，UE2和UE3可能对UE1产生CLI。相应的，UE1可称为第一终端，UE2和UE3可称为第二终端。在其他通信场景中，比如，UE1进行上行发送，则UE1可称为第二终端，相应的，可能被UE1的上行发送干扰的UE2、UE3可称为第一终端。典型的，UE1和UE2可以为相邻小区各自所属的UE。但是在一些特殊情形，例如全双工场景中，UE1和UE2可以为同一小区所属的UE。
在本申请实施例中，第一SRS指的是用于检测CLI的SRS。某一干扰终端在第一资源上发送第一SRS。被干扰终端监听该第一SRS，并在接收到该第一SRS后，测量该第一SRS的信号强度，得到该第一SRS的测量结果。可选的，该测量结果可以为层3(layer3,L3)测量结果，即对测量该第一SRS的信号强度进行过滤得到L3测量结果。其中，过滤可以是层3过滤，进行层3过滤所用的参数都可以被配置。可选的，测量该第一SRS的信号强度可以为层1(layer 1,L1)测量结果。
容易理解的是，不同的第二终端均可以发送第一SRS，第一终端可以监听来自一个或多个第二终端的第一SRS，进而判定相对应的第一SRS的信号强度。图3中以两个第二终端向第一终端发送第一SRS为例。
S302、第一终端根据至少一个第一SRS，获得至少一个第二终端的测量结果的信息。
其中，测量结果用于表征第二终端发送的第一SRS的信号强度。
容易理解的是，第一终端监听到来自一个或多个第二终端的第一SRS之后，可以测量每一第一SRS的信号强度，以获取不同第二终端的测量结果。其中，某一第二终端的测量结果表征该第二终端发送的第一SRS的信号强度，还可以表征该第二终端对第一终端的CLI干扰程度。并且，第二终端发送的第一SRS的信号强度越强，即测量结果的数值越大，说明第二终端对第一终端的CLI干扰程度越严重。可选的，第一终端测量第一SRS的信号强度，可以是第一终端测量第一SRS的RSRP，并将第一SRS的RSRP作为第一SRS的测量结果。或者，第一终端测量第一SRS的RSSI，并将第一SRS的RSSI作为第一SRS的测量结果。或者，还可以是将第一SRS的RSRP以及RSSI均作为第一SRS的测量结果。或者，还可以将其他指标作为第一SRS的测量结果。这里不再一一列举。第一终端具体使用哪一指标作为测量结果，可以由网络设备通过配置信息来指示。或者，由第一终端根据自身预配置规则确定使用哪一指标作为测量结果。第一终端使用哪一指标作为测量结果的详细介绍可参见后文。
可选的，测量结果可以是第一终端在第一时间段对第一SRS的测量取样进行推导，过滤或计算所得。具体的，测量结果可以是所述第一时间段内对第一SRS的测量取样的平均值，例如，为所述第一时间段对第一SRS的测量取样根据不同的参数进行加权的平均值。其中，对第一SRS的测量所设置的所述第一时间段可以被配置。
可选的，测量结果还可以是第一终端在第二时间段对第一SRS的测量取样进行推导，过滤或计算所得。具体的，测量结果可以是所述第二时间段内对第一SRS的测量取样大于第四门限值的比例，例如，为所述第二时间段对第一SRS的测量取样100个，有60个大于第四门限值，则该测量结果表示为60％。其中，对第一SRS的测量所设置的所述第二时间段可以被配置。所述第一时间段和所述第二时间段可以相同或不同。所述第四门限值可以被配置。
所述一个或多个测量结果的信息包含所述一个或多个测量结果的指示信息，和/或第二指示信息。
其中，测量结果的指示信息为指示测量结果的信息，终端设备可以直接上报测量结果或者测量结果的索引或者测量结果的标识或者其他指示测量结果的信息。本申请实施例主要以上报测量结果为例进行说明，可以理解的是，只要是终端最终能够将测量结果的相关信息告知网络设备，使得网络设备获知测量结果，就应当在本申请实施例方案的保护范围内。
所述第二指示信息为所述一个或多个测量结果分别对应的第二终端的指示信息。即第二指示信息可以用于区分不同的第二终端。可选的，所述第二指示信息包括第一SRS的资源指示信息，或第一SRS序列或第一SRS序列集合中的一种或多种。当然，第二指示信息还可以是其他能够区分不同第二终端的信息。第二指示信息的详细介绍可参见下文。
S303、第一终端获得第一指示信息。
其中，第一指示信息用于指示第一终端上报测量结果的信息。可选的，第一指示信息指示第一终端上报测量结果的数目，所上报测量结果的特征中的至少一项。
可选的，第一指示预配置在第一终端中，或者，第一指示信息由网络设备配置给第一终端。
其中，其中步骤303与301，302顺序不限定，可以先后或同时。示例性的，第一终端可以先获取第一指示信息，再从第二终端接收第一SRS，并测量第一SRS的测量结果。也可以是先从第二终端接收第一SRS，再获取第一指示信息。
可选的，所上报测量结果的特征可以包含：上报的测量结果为第一SRS的RSRP，或者上报的测量结果为RSSI，或者上报的测量结果为第一SRS的RSRP及RSSI。
S304、第一终端根据第一指示信息，向网络设备发送一个或多个测量结果的信息。
相应的，网络设备从第一终端接收一个或多个测量结果的信息。
本申请实施例提供的通信方法，某一第二终端发送第一SRS之后，若第一终端可以监听到该第二终端的第一SRS，则第一终端可以测量该第一SRS的信号强度，进而得到该第一SRS的测量结果的信息。并且，第一终端还可以将测量结果的信息上报至网络设备，使得网络设备能够获取到不同第二终端的测量结果。如此，在后续，网络设备可以基于一个或多个测量结果获知不同第二终端对第一终端的CLI程度，并执行一些降低CLI的操作。
此外，网络设备在不获取测量结果的情况下，可以根据测量结果对应的第二指示信息获知对第一终端产生干扰的具体是哪些第二终端。比如，第一终端测量某一第一SRS，并向网络设备反馈该第一SRS的第二指示信息，包括但不限于该第一SRS序列， 或者该第一SRS序列集合，或者，该第一SRS的资源标识中的至少一个时，网络设备能够确定该第一SRS的发送端。比如，第一终端测量某一第一SRS，并向网络设备反馈该第一SRS的资源标识，由此，网络设备可以知道使用该资源发送第一SRS的第二终端是哪一终端，进而网络设备可确定对第一终端产生CLI的干扰源。
如下说明当第一指示信息不同时，第一终端上报测量结果的方式不同，即上述S303和S304的具体实现。其中，如下各个流程中均以第一指示信息由网络设备配置为例，对于第一指示信息预配置在终端中的实现流程，可参见下文描述，本申请实施例不再重点描述。
在一些实施例中，参见图7，S303可以具体实现为：
S3031、第一终端从网络设备接收第一指示信息。
其中，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中最大的N个测量结果的信息。换句话说，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中最大的N个测量结果和/或所述最大的N个测量结果分别对应的第二指示信息，或者最小的N个测量结果和/或所述最小的N个测量结果分别对应的第二指示信息。N为大于或等于1的整数。也就是说，第一终端可上报最大的N个测量结果，或者，上报最大的N个测量结果分别对应的第二指示信息，或者，同时上报最大的N个测量结果和所述最大的N个测量结果分别对应的第二指示信息。或者，上报最小的N个测量结果，或者，上报最小的N个测量结果分别对应的第二指示信息，或者，同时上报最小的N个测量结果以及所述最小的N个测量结果分别对应的第二指示信息。后文出现类似描述时，其原理可参见这里。
可选的，N值可以与至少一个第二终端的测量结果数目相同。即第一终端监听到几个测量结果，就上报全部的测量结果。如此，网络设备接收全部测量结果，由于全部测量结果可以全面、精准的反映不同第二终端的第一SRS信号强度，所以，网络设备能够获知全面、精准的第一终端与不同第二终端之间的CLI情况。进而，基于精准的CLI情况，执行一些降低CLI操作。
可选的，N值可以小于至少一个第二终端的测量结果数目。仅上报部分测量结果，使得上报测量结果的信令开销有所降低。
可选的，N个测量结果为至少一个第二终端的测量结果中最大的N个测量结果，即上报测量结果的特征为最大的测量结果。N为大于或等于1的整数。其中，N值可以由厂商根据规定预配置在终端中，或者，N由网络设备发送给终端，终端存储N值。作为一种可能的实现方式，至少一个第二终端的测量结果数目大于或等于N，第一终端向网络设备发送N个测量结果。示例性的，第一终端监听到5个来自不同第二终端的第一SRS，这5个第一SRS的测量结果的大小依次为：测量结果3(对应UE3的SRS 3)>测量结果2(对应UE2的SRS 2)>测量结果5(对应UE5的SRS 5)>测量结果4(对应UE4的SRS 4)>测量结果1(对应UE1的SRS 1)，假设N取值为3，则第一终端向网络设备分别上报UE3、UE2、UE5的测量结果。
如此，由于当某一第二终端的测量结果越大时，该第二终端对第一终端的CLI程度通常越强。网络设备基于CLI程度最强的测量结果就可以大致获知第一终端和其他终端之间的CLI情况，以便于执行一些降低CLI的操作，以降低第一终端和其他终端之 间的CLI。可见，仅上报部分测量结果，使得上报测量结果的信令开销有所降低。
S304可以具体实现为如下步骤：
S3041、第一终端根据第一指示信息，向网络设备发送N个测量结果的信息。
相应的，网络设备从第一终端接收N个测量结果的信息。
在另一些实施例中，参见图8，S303可以具体实现为如下S3032：
S3032、第一终端从网络设备接收第一指示信息。
其中，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中大于或等于第一门限值的J个测量结果的信息，J个测量结果的信息包括J个测量结果的指示信息和/或第二指示信息，所述第二指示信息为所述J个测量结果对应的第二终端的指示信息，J为正整数。
可选的，第一终端上报的一个或多个测量结果为J个测量结果的信息。J为正整数，J由网络设备发给第一终端，或者预配置在第一终端中。具体的，第一终端上报的J个测量结果为至少一个第二终端的测量结果中测量结果大于或等于第一门限值的J个测量结果。如此，仅上报部分测量结果，能够降低上报测量结果的信令开销。比如，第一终端监听到5个来自其他终端的第一SRS，J取值为3，则第一终端上报大于或等于第一门限值的3个测量结果。在一种情况中，若大于或等于第一门限值的测量结果数目小于J，比如，仅存在1个大于或等于第一门限值的测量结果，则第一终端设备可以仅上报该1个测量结果。或者，第一终端上报该1个测量结果，再从其余4个测量结果中选取2个最大的测量结果，上报该2个最大的测量结果。在另一情况中，若不存在大于或等于第一门限值的测量结果，则第一终端可以不上报测量结果。或者，随机选取J＝3个测量结果进行上报。在另一情况中，当大于或等于第一门限值的测量结果的个数大于J个时，第一终端只上报J个测量结果。或者，第一终端上报大于或等于第一门限值的全部测量结果。
当然，还可以设置其他门限值，比如第三门限值。可选的，第一终端上报大于或等于第三门限值的测量结果。可选的，当不存在大于或等于第三门限值的测量结果时，第一终端上报最大的一个或者M个测量结果。1个或者M个由网络设备配置或者预先配置在第一终端中。M为正整数。
可选的，上述门限值均可以预配置在终端中，或者，均由网络设备发给终端。或者，某些门限值预配置在终端中，某些由网络设备配置。
区别于图7所示的测量结果上报方式，图7所示流程中上报的N个测量结果可能低于预设的第一门限值，通过图8所示流程，可以指示UE上报大于或等于第一门限值的J个测量结果的信息。当UE实际测量所得的测量结果中大于或等于第一门限值的测量结果个数不够J个时，可以只上报大于或等于第一门限值的测量结果。其中不够的含义为小于。
如此，仅发送一部分测量结果，可以降低信令开销。并且，可以发送最大的J个测量结果，使得网络设备获知对第一终端CLI程度较严重的第二终端，以便于网络设备根据最严重CLI情况制定降低干扰的策略。或者，上报最小的J个测量结果，使得网络设备可以获知哪些第二终端对第一终端的CLI程度较轻，进而，可以不对这些第二终端的干扰进行其他操作。
S304可以具体实现为如下S3042：
S3042、第一终端根据第一指示信息，向网络设备发送至少一个第二终端的测量结果中大于或等于第一门限值的J个测量结果的信息。所述J个测量结果的信息包括J个测量结果的指示信息和/或第二指示信息，所述第二指示信息为所述J个测量结果对应的第二终端的指示信息。
在另一些实施例中，参见图9，上述S303可以具体实现为如下S3033：
S3033、第一终端从网络设备接收第一指示信息。
其中，第一指示信息用于指示第一终端发送至少一个第二终端的测量结果中小于或等于第二门限值的W个测量结果的信息。所述W个测量结果的信息包括W个测量结果的指示信息和/或第二指示信息，所述第二指示信息为所述W个测量结果对应的第二终端的指示信息，W为正整数。
示例性的，若至少一个第二终端的测量结果数目大于W，则第一终端上报W个测量结果。如此，可降低信令开销。在一种情况下，至少一个第二终端的测量结果数目小于W，此时，第一终端可上报至少一个第二终端的全部测量结果。在一种情况下，若不存在小于或等于第二门限值的测量结果，则第一终端可从至少一个第二终端的测量结果中随机选取(比如选取最小的)W个测量结果，并上报W个测量结果。或者，若不存在小于或等于第二门限值的测量结果，第一终端可以不上报任何测量结果。本申请实施例对第一终端上报测量结果的数目不做具体限定。
上述S304可以具体实现为如下S3043：
S3043、第一终端根据第一指示信息，向网络设备发送至少一个第二终端的测量结果中小或等于第二门限值的W个测量结果的信息。所述W个测量结果的信息包括W个测量结果的指示信息和/或第二指示信息，所述第二指示信息为所述W个测量结果对应的第二终端的指示信息。
在另一些实施例中，参见图10，上述S304还可以实现为如下步骤：
S3044、在第一时间，第一终端向网络设备发送第一测量结果的信息。第一测量结果的信息包括第一测量结果和/或所述第一测量结果对应的第二指示信息。
S3045、在与第一时间间隔预设时段的第二时间，第一终端向网络设备发送第二测量结果的信息，即发送第二测量结果和/或所述第一测量结果分别对应的第二指示信息。第二测量结果与第一测量结果的差值大于或等于预设差值。
本申请中第一时间与第一时间段没有相关关系，第二时间与第二时间段没有相关关系。
也就是说，上报不同测量结果的时刻存在时间间隔。作为一种可能的实现方式，第二测量结果与第一测量结果的差值大于或等于预设差值。也就是说，当上报两次测量结果时，第一终端只有在确定第二次的测量结果与第一次测量结果的差值大于或等于预设差值之后，才上报第二次测量结果。
两次上报的时间间隔，即预设时段可以为预配置，或者，由网络设备发给第一终端。预设差值可以为预配置，或者，由网络设备发给第一终端。
其中，两次测量结果可以是针对同一第二终端的第一SRS的测量结果的信息。也就是说，可以对同一第二终端测量多次第一SRS，并周期性上报多次的测量结果。以 UE1为第一终端，UE2为第二终端为例，在UE1周期性上报UE2的测量结果的过程中，两次测量结果的差值大于或等于预设差值，指的是第二次测量结果比第一次测量结果大，并且，第二次测量结果与第一次测量结果的差值等于预设差值。或者，第二次测量结果比第一次测量结果大，且，第二次测量结果与第一次测量结果的差值大于预设差值。或者，两次测量结果的差值大于或等于预设差值，还可以是第二次测量结果比第一次测量结果小，且，第二次测量结果与第一次测量结果的差值等于预设差值。或者，第二次测量结果比第一次测量结果小，且，第二次测量结果与第一次测量结果的差值大于预设差值。也就是说，当第二次测量结果与第一次测量结果的差异较大，第一终端才会上报针对同一第二终端的第二次测量结果。采用上述方法，针对同一第二终端可以测量多次第一SRS，可提升该第二终端的第一SRS的测量结果的准确性。进一步的，数值相近的测量结果通常说明第二终端的位置、信号质量等未发生变化，或者变化不大，此种情况下，获取道第二终端的第一SRS的测量结果可能是冗余信息，网络设备可能并不需要该冗余信息来进行决策。因此，在本申请实施例中，第一终端仅上报与第一次测量结果相差较大的第二次测量结果，如此，能够避免第一终端上报数值相近的冗余测量结果，降低了信令开销。
或者，两次测量结果可以是针对不同第二终端的第一SRS的测量结果的信息。以第一终端为UE1，第二终端为UE2、UE3为例，在第一时间，UE1向网络设备发送UE2的第一SRS的测量结果，在第二时间，UE向网络设备发送UE3的第一SRS的测量结果。这种情况下，两次测量结果的差值大于或等于预设差值，可以指UE3的测量结果比UE2的测量结果大，且UE3的测量结果与UE2的测量结果的插值大于或等于预设差值。或者，也可以指UE3的测量结果比UE2的测量结果小，且UE3的测量结果与UE2的测量结果的差值大于或等于预设差值。
在另一些实施例中，第一终端、第二终端和网络设备之间可以通过一些交互流程来配置第一SRS，以便于第一终端测量第一SRS。具体的，参见图11，交互流程包括如下步骤：
S1101、第一终端向网络设备发送第一能力信息。
相应的，网络设备从第一终端接收第一能力信息。
其中，第一能力信息指示用于测量CLI的能力信息。第一能力信息包括以下至少一个：第一终端在一个时间单元上能够监听的第一SRS数目、第一终端是否能够监听连续符号、第一终端在一个时间单元上能够监听的最大符号数目、第一终端在一个时间单元上能够监听的最大连续符号数目。时间单元可以是时隙(slot)。一个时间单元包含一个slot，或者包括多个slot,或者包括一个持续时间duration，一个duration包括一个或多个时隙中任何一个或多个的组合。
作为另一个实施例，S1101步骤为可选项，即可以不执行该步骤，继续下述步骤。
在另一些实施例中，第一终端还可以向运维管理(operation administration management，OAM)系统上报第一能力信息。
S1102、第一终端向网络设备发送第二能力信息。
相应的，网络设备从第一终端接收第二能力信息。第二能力信息指示第一终端用于上报测量结果的能力。第二能力信息用于指示第一终端能够向网络设备上报的测量 结果的数目，测量结果包括针对至少一个第一SRS的测量结果。第一SRS的测量结果表征该第二终端发送的第一SRS的信号强度，还可以表征该第二终端对第一终端的CLI干扰程度。关于第一SRS的测量结果的详细介绍可参见下文。此外，下文再提及测量结果时，通常指的是针对第一SRS的测量结果，在此统一说明，下文不再赘述。
可选的，第二能力信息也可称为第一终端的上报能力。
其中，测量结果还可以包括其他类型的测量结果。比如，可以包括RSRP的测量结果，或者，RSRQ的测量结果，或者，接收信号强度指示(received signal strength indicator，RSSI)的测量结果。也就是说，第一终端通过第二能力信息，使得网络设备获知第一终端能够上报的针对RSRP的测量结果数目，和/或，获知针对RSRQ的测量结果数目，和/或，获知针对RSSI的测量结果数目，和/或，获知能上报的第一SRS的测量结果数目。进而，网络设备根据第一终端能够上报的测量结果数目为第一终端进行相关配置。
作为另一个实施例，S1102步骤为可选项，即可以没有该步骤，继续下述步骤。
S1103、第一终端向网络设备发送第三能力信息。
相应的，网络设备从第一终端接收第三能力信息。
其中，第三能力信息用于指示第二资源与传输第一SRS的第一资源之间的复用关系，复用关系包括时分复用，或频分复用中至少一种。频分复用具体为：第一资源与第二资源在时域资源上相同，频域资源上相邻或不重叠；或者，时域资源上有部分重叠(overlap)，频域资源上相邻或不重叠。时分复用具体为：第一资源与第二资源在频域资源上相同，时域资源上相邻或不重叠；或者，频域资源上有部分重叠(overlap)，时域资源上相邻或不重叠。
第一资源为用于传输第一SRS的资源。第二资源为用于数据传输的资源。数据传输包括下述任何一种或多种：物理下行共享信道(physical downlink shared channel，PDSCH)、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)、物理下行控制信道(physical downlink control channel，PDCCH)、信道状态指示参考信号(channel state indicator reference signal，CSI-RS)、物理上行控制信道(physical uplink control channel，PUCCH)、物理侧行链路控制信道(physical sidelink control channel，PSCCH)、或物理侧行链路共享信道(physical sidelink shared channel，PSSCH)、物理侧行链路反馈信道(physical sidelink feedback channel，PSFCH)。当然，数据传输还可以是其他形式的数据传输。
需要说明的是，第三能力信息指示第一资源和第二资源之间的复用关系，可以是指示第一资源和第二资源之间具有哪一种或哪几种复用关系，该资源复用关系可以被第一终端支持。比如，第三能力信息指示第一资源和第二资源之间为时分复用。或者，第三能力信息指示第一资源和第二资源之间不能具有哪一种或哪几种复用关系，即第一终端不支持哪一种或几种资源复用关系。比如，第三能力信息指示第一资源和第二资源之间不能为频分复用，或者，第一资源和第二资源之间在时频资源上不能有包含(比如重叠)关系，或者，第一资源和第二资源之间在时频资源上不能有重叠。
如此，当网络设备收到上述第三能力信息时，在为终端配置第一资源和第二资源时，会根据终端支持或不支持的资源复用关系，合理进行资源配置，降低第一资源和第二资源发生冲突的概率。
在一些实施例中，第一SRS占用的资源不同于下行传输的资源，且第一SRS占用的资源不同于上行传输的资源。下行传输包括PDCCH、或PDSCH、或同步信号(synchronization signal，SS)、或物理广播信道(physical broadcast channel，PBCH)；上行传输包括PUCCH、或PUSCH、或PRACH、或第二SRS中的至少一项。其中，第二SRS不是用于检测CLI的SRS。当然，上行传输和下行传输还可以为其他形式的上行传输或下行传输。
也就是说，网络设备在配置上行传输或下行传输时，考虑上行传输或下行传输是否与第一SRS产生重叠。若产生重叠，则网络设备将某一资源要么配置成用于上行传输或下行传输，要么配置成用于传输第一SRS。以避免在同一资源上出现上行或下行传输与第一SRS的冲突。
或者，定义终端行为如下。当第一SRS占用的资源与下行传输的资源中部分资源相同，或第一SRS占用的资源与上行传输的资源中部分资源相同，在相同的资源上，第一SRS被终端检测且下行传输被终端丢弃，或者，下行传输被终端检测且第一SRS被终端丢弃，或者，第一SRS被终端检测且上行传输被终端丢弃，或者，上行传输被终端检测且第一SRS被终端丢弃。
以网络设备配置上述任一上行传输为例，在同一资源上，网络设备将该资源配置成用于上行传输和用于传输第一SRS。并且，网络设备可以指示第一终端在该资源上检测时，优先检测上行传输，不检测第一SRS，即丢弃第一SRS。或者，第一终端优先检测第一SRS，不检测上行传输。
作为另一个实施例，S1103步骤为可选项，即可以没有该步骤，继续下述步骤。S1103步骤为可选项时，第一终端获取第三能力信息为通过预先设置获取。
本申请实施例不限制S1101至S1103之间的执行顺序，示例性的，第一终端可以先向网络设备发送第一能力信息，再向网络设备发送第二能力信息。第一终端还可以先向网络设备发送第三能力信息，再向网络设备发送第一能力信息，等。
所述第一能力信息，第二能力信息或第三能力信息中任何一个都可以由终端置放于MAC包或者数据包中发给网络设备。
S1104、第一终端获取配置信息。
可选的，第一终端从网络设备获取配置信息。或者，配置信息预先配置在第一终端中。或者配置信息的一部分从网络设备接收，配置信息的另一部分预先设置。
作为一种可能的实现方式，网络设备基于第一终端的上述能力信息中的至少一个(比如第二能力信息)确定配置信息。当然，网络设备还可以基于自身策略确定配置信息，并向第一终端发送配置信息。本申请实施例对网络设备确定配置信息的方式不做限定。
在一些实施例中，配置信息用于指示下述至少一项：
1、上报的测量结果为RSRP，或者RSSI，或者RSRP及RSSI。测量结果用于表征第一SRS的信号强度。
本申请中，作为第一SRS的信号强度表征的测量结果为RSRP，或者RSSI，或者RSRP及RSSI。其中，RSRP可以替换为SRS-RSRP，也可以替换为CLI-RSRP。RSSI可以替换为SRS-RSSI，也可以替换为CLI-RSSI。
2、可用的第一资源的信息或者配置的第一资源的信息。
可选的，可用第一资源指的是干扰终端发送第一SRS可使用的资源。在一种可能的实现方式中，可以预先规定资源池，资源池即为可用第一资源。可用的第一资源的信息包括资源池的起始时隙(slot)位置，slot个数，在一个slot中起始的正交频分复用(orthogonal frequency division multiplexing，OFDM)符号位置，符号个数，起始的物理资源块(physical resource block，PRB)位置，或PRB个数，起始的资源元素(resource element，RE)位置，或RE个数的一种或者多种的组合。其中slot个数，符号个数，PRB个数中任何一种或者多种可以是连续的或者非连续的。
可选的，网络设备也可以限制第一资源的最小PRB数目。比如COMB＝2时，设置第一资源占用的PRB数目不小于8个，COMB＝4时，设置PRB数目不小于16个。
如此，后续，当第一终端作为干扰终端时，其可在可用的第一资源(即上述资源池)中选取用于发送第一SRS的资源。
可选的，配置的第一资源指的是干扰终端发送第一SRS所使用的资源。配置的第一资源的信息包括起始slot位置，slot个数，在一个slot中起始的OFDM符号位置，符号个数，起始的PRB位置，PRB个数，起始的RE位置，或RE个数的一种或者多种的组合。其中slot个数，符号个数，PRB个数，RE个数中任何一种或者多种可以是连续的或者非连续的。
3、用于测量RSSI的参考信息。
其中，用于测量RSSI(可以理解为用于传输RSSI)的参考信息包括参考子载波间隔(subcarrier spacing，SCS)，用于测量RSSI的起始slot位置，用于测量RSSI的slot个数，用于测量RSSI的起始OFDM符号位置，用于测量RSSI的符号个数，用于测量RSSI的起始PRB位置，用于测量RSSI的PRB个数，用于测量RSSI的起始RE位置，或用于测量RSSI的RE个数的一种或者多种的组合。其中slot个数，符号个数，PRB个数，RE个数中任何一种或者多种可以是连续的或者非连续的。
当用于RSSI测量的参考子载波间隔被配置后，第一终端所在的激活(active)带宽部分(bandwidth partial，BWP)上的子载波间隔可能不同于用于RSSI测量的参考子载波间隔。不同子载波间隔定义的符号和带宽可能不同。示例性的，假设active BWP上的子载波间隔为20kHZ，用于RSSI测量的参考子载波间隔为40kHZ。则当网络设备将第一终端配置成在测量RSSI时检测4个符号(即用于RSSI测量的符号)时，第一终端测量RSSI时，由于用于RSSI测量的参考子载波间隔加倍(由20kHZ至40kHZ)，则第一终端实际检测2个符号。
在一种情况中，网络设备配置用于RSSI测量的符号个数为奇数个，那么，第一终端根据active BWP的子载波间隔与用于RSSI测量的参考子载波间隔之间的关系推导所得的实际测量符号可能不是整数。因此，需要重新确定终端的实际测量符号和带宽。
作为一种可能的实现方式，采用下取整或者上取整方式确定实际测量符号。比如，UE被网络设备配置为测量7个符号，但是用于RSSI测量的参考子载波间隔是active BWP子载波间隔的二倍。那么，在这种情形下，UE实际是被配置测量3.5个符号。可选的，对3.5进行下取整后，则UE实际测量3个符号。或者，对3.5上取整后，则UE实际测量4个符号。也可以说，当用于测量RSSI的参考子载波间隔定义的符号或符号个数不满足激活BWP SCS定义的整数符号的要求时，UE可以通过向上取整或向下取整 方式确定实际测量的符号数，以满足激活BWP SCS的整数符号要求。
此外，当用于RSSI测量的参考子载波间隔定义的RB，或RB个数，或PRB，或PRB个数，或RE，或RE个数中的至少一个不满足激活BWP SCS定义的整数RB/RE时，UE也可以参照上述方法计算出整数RB/RE中任何一者。作为一种可能的实现方式，可以是对符号进行下取整，对RB/RE进行上取整，或者，对符号进行上取整，对RB/RE进行下取整，或者，采取其他取整方式。所述取整方式可以被配置或预先设置在终端。
4、用于测量RSRP的参考信息。
其中，可参见配置的第一资源的信息。这里不再赘述。
需要说明的是，用于测量RSRP的参考信息可以与上述用于测量RSSI的参考信息分别独立配置，两者互不影响。所配置的传输资源可以有下述几种关系，比如，用于测量RSRP的第一SRS占用资源1，用于测量RSSI的占用资源2，且资源1和资源2可以部分重叠，或者不重叠，也可以完全重叠。本申请中占用资源可以替换为使用资源。
此外，第一终端能够上报RSSI和上报RSRP的数目可以不同，也可以相同。可以根据实际应用场景灵活配置。
5、用于发送/测量的第一SRS的序列(sequence)、序列集合或者资源指示信息中
的至少一项。其中，每一序列集合包含至少一个序列。
具体的，指的是第一SRS的根序列或者根序列集合，每一根序列集合包含至少一个根序列。如此，可以基于配置的根序列进行循环移位得到需发送/需测量的第一SRS。或者，从根序列集合中随机选取根序列，并通过循环移位得到需发送的第一SRS。
具体的，指的是第一SRS的根序列、循环移位、根序列集合、或者循环移位集合中任何一种或多种的组合。每一根序列集合包含至少一个根序列。如此，可以基于配置的根序列和循环移位得到需发送/需测量的第一SRS。或者，从根序列集合中随机选取根序列，并通过循环移位得到需发送的第一SRS。
具体的，资源指示信息包含用于传输的资源或资源集合。用于传输的资源可以通过资源标识(index/ID)来表示，如SRS resource index；资源集合可以通过资源集合标识(index/ID)来表示,如SRS set resource index或者SRS resource set index。
6、是否为第一终端做速率匹配。
其中，为第一终端做速率匹配指的是，针对第一终端传输的上行或下行信息进行重发(repeated)或者打孔(punctured)，以匹配物理信道的承载能力，上行或下行信息的传输速率达标。关于速率匹配的详细介绍可参见现有技术，这里不再赘述。如此，后续，若需做速率匹配，则第一终端使用重发或打孔方式发送信息，以匹配物理信道的承载能力。
7、上报测量结果的信息既包含测量结果，还包含第二指示信息。
上报测量结果包括同时上报所测量的第一SRS的第二指示信息。其中，第一SRS的第二指示信息包括第一SRS的资源指示信息，或第一SRS序列中的一种或多种的组合。本申请实施例中，第一SRS的资源指示信息包括：第一SRS资源标识或第一SRS资源索引，或第一SRS集合资源标识，或第一SRS集合资源索引中的一种或多种的组合。即，向网络设备发送一个或多个测量结果包括在发送测量结果的同时，也上报所测量的第一SRS的第二指示信息。第一SRS集合包括一个或多个第一SRS，第一SRS集合资源标识，可以使用于传输多个第一SRS的全部资源的标识。
也就是，通过配置信息可以指示第一终端在上报测量结果同时，还上报其他一些信息。如此，通过一条消息，可以携带第一终端相关的资源、序列等信息。所述测量 结果与第二指示信息在上报的消息中一一对应。
8、测量结果的信息只包含第二指示信息。上报测量结果只上报所测量的满足测量结果要求的第一SRS的第二指示信息。其中，满足测量结果要求即满足第一指示信息要求。其中，第一SRS的第二指示信息包括第一SRS的资源指示信息，或第一SRS序列中的一种或多种的组合。本申请实施例中，第一SRS的资源指示信息包括：第一SRS资源标识或第一SRS资源索引，或第一SRS集合资源标识，或第一SRS集合资源索引中的一种或多种的组合。即，向网络设备发送一个或多个测量结果包括在发送测量结果的同时，也上报所测量的第一SRS的第二指示信息。第一SRS集合包括一个或多个第一SRS，第一SRS集合资源标识，可以使用于传输多个第一SRS的全部资源的标识。
也就是，通过配置信息可以指示第一终端在上报测量结果时，只上报其他一些信息。如此，并不直接上报测量结果自身，可以携带第一终端相关的资源、序列等信息。所述测量结果与第二指示信息一一对应。
9、测量结果的信息只包含测量结果。
在另一些实施例中，配置信息还可用于指示第一终端上报测量结果的方式。上报测量结果的方式包括上报测量结果的数目，以及上报测量结果的特征。当上报测量结果的方式为如下至少一种或多种的组合时，第一终端根据配置信息所指示的上报测量结果的方式进行上报。具体的，上报测量结果的方式可以为如下至少一种或多种的组合：
方式1：第一终端按照图7所示方法流程上报N个测量结果的信息。
方式2：可以设置不同门限值，并基于不同门限值判断需上报的测量结果。即第一终端按照图8所示方法流程上报测量结果的信息。
方式3：第一终端按照图9所示方法流程上报W个测量结果的信息。
方式4：第一终端上报来自第一小区中第二终端的K个测量结果的信息，上报来自第二小区中第二终端的I个测量结果的信息。其中，I、K均为正整数，I、K可以相同，也可以不同。也就是说，针对不同小区中的第二终端，第一终端针对不同小区可设置不同的测量结果数目上限。
方式5：第一终端上报的测量结果为至少一个第二终端的测量结果中测量结果大于或等于结果阈值，且测量结果最大的H个测量结果，H为正整数。
方式6：第一终端按照预设时间间隔上报不同的测量结果的信息。即按照图10所示流程上报测量结果。
方式7：第一终端上报第一SRS的第二指示信息。
所述上报第一SRS的第二指示信息包括在上报测量结果的同时，上报测量结果对应的第二指示信息。即第二指示信息与测量结果一一对应上报。
可选的，当上报两个测量结果时，同时上报这两个第一SRS各自的资源标识/资源索引，从而使得网络设备获取到该测量结果的同时知道测量结果对应的是来自哪个终端的干扰。
可选的，当上报两个测量结果时，同时上报这两个第一SRS各自的第一SRS集合资源标识/第一SRS集合资源索引，从而使得网络设备获取到该测量结果的同时知道测量结果对应的是来自哪个终端的干扰。
可选的，当上报两个测量结果时，同时上报这两个第一SRS各自的资源标识/资源索引以及集合资源标识/SRS集合资源索引，即同时上报这两个第一SRS各自的资源标 识以及第一SRS集合资源标识，或者，同时上报这两个第一SRS各自的资源标识以及第一SRS集合资源索引，或者，同时上报这两个第一SRS各自的资源索引以及第一SRS集合资源索引，或者，同时上报这两个第一SRS各自的资源索引以及第一SRS集合资源标识。从而使得网络设备获取到该测量结果的同时知道测量结果对应的是来自哪个终端的干扰。
可选的，当上报两个测量结果时，同时上报这两个第一SRS各自的序列，从而使得网络设备获取到该测量结果的同时知道测量结果对应的是来自哪个终端的干扰。
所述上报第一SRS的第二指示信息包含：所述第二指示信息与一个或多个测量结果一一对应上报。
可选的，当上报两个测量结果时，同时上报这两个第一SRS各自的资源标识/资源索引以及序列，从而使得网络设备获取到该测量结果的同时知道测量结果对应的是来自哪个终端的干扰。
可选的，可以采用同一条配置信息上报第一SRS的序列或者序列集合和第二指示信息。与可以采用两条配置信息分别上报第一SRS的序列或者序列集合和第二指示信息。本申请实施例对此不进行限制。
可选的，所述上报第一SRS的第二指示信息包括只上报第二指示信息，从而使得网络设备并不需要获取测量结果但能获知哪个终端的干扰最强或者最弱。
当然，第一终端还可以采取其他方式来上报测量结果，上报其他数目的测量结果，并且，上报的测量结果还可以具备其他特征，本申请实施例在此不再一一列举。
上述N、J、M、K、I、H的值，第一门限值，或第二门限值中任意一者或多者。
可选的，第一终端除了根据网络设备的配置信息进行上报，第一终端也可以根据上述上报测量结果的方式中的任何一种或者多种的组合直接进行上报。即，第一终端不需要获取网络设备下发的配置信息来获知上报测量结果的方式，或者，第一终端根据预先设置直接上报。本申请中上报的含义为从终端向网络设备发送数据信息，该数据信息包括测量结果以及对测量结果的第二指示信息中任何一种或多种。
例如，第一终端直接根据方式1上报，或者第一终端直接根据方式1以及6上报，或者第一终端直接根据方式2以及6上报。
作为另一个实施例，S1104步骤为可选项，即可以没有该步骤，继续下述步骤。S1104步骤为可选项时，第一终端获取配置信息为通过预先设置获取。
S1105、网络设备配置第二终端的第一SRS。
在一些实施例中，网络设备基于上述至少一种能力信息(比如第一能力信息)配置第二终端的第一SRS。
可选的，第一能力信息也可以称之为测量能力。
如下以时间单元为时隙，第一终端为UE1，第二终端为UE2、UE3为例，对网络设备配置第二终端的第一SRS的方法进行说明。
可选的，网络设备基于UE1上报的第一能力信息获知UE1在一个时隙中能够监听的第一SRS数目为P，P为大于或等于1的整数。如此，网络设备将第二终端能够发送的第一SRS数目配置为小于或等于P。比如，UE1在一个时隙中能够监听的第一SRS数目为8，且UE2、UE3复用一个时隙，则网络设备可以将UE2配置成在一个时隙中 最多发送2个第一SRS，网络设备将UE3配置成在同一个时隙中最多发送6个第一SRS。或者，UE2、UE3不在同一时隙中发送第一SRS，则网络设备可以将UE2配置成在一个时隙中最多发送8个第一SRS，网络设备将UE3配置成在同一个时隙中最多发送8个第一SRS。这样一来，无论UE2、UE3是否复用同一时隙发送第一SRS，在一个时隙中，UE2或UE3最多发送8个第一SRS，不超出UE1在一个时隙中监听第一SRS数目的上限。
可选的，网络设备基于UE1上报的第一能力信息获知UE1能够监听连续符号，相应的，网络设备将UE2配置成在连续符号上发送第一SRS。或者，网络设备将UE3配置成在连续符号上发送第一SRS。或者，若UE2、UE3复用同一时隙发送第一SRS，则网络设备可以将连续的多个符号分配给UE2、UE3，用于发送第一SRS。
可选的，网络设备基于UE1上报的第一能力信息获知UE1在一个时隙上能够监听的最大符号数目为L，L为大于或等于1的整数。如此，若UE2、UE3复用同一时隙发送第一SRS，则网络设备可以将UE2配置成在一个时隙中最多使用L1个符号发送第一SRS，将UE3配置成在一个时隙中最多使用L2个符号发送第一SRS，并且，L1+L2小于或等于L。当然，当L1个符号与L2个符号有重叠时，L1+L2可以大于L，只要保证L1小于或等于L，并且L2小于或等于L。类似的，UE2、UE3不在同一时隙中发送第一SRS时，也能够保证，在一个时隙中用于发送第一SRS的最大符号数目不超出UE1能够监听的数目。
可选的，网络设备基于UE1上报的第一能力信息获知UE1在一个时隙上能够监听的最大连续符号数目。如此，网络设备为UE2或UE3配置的用于发送第一SRS的连续符号的数目小于或等于该最大连续符号数目。
可选的，第一终端在一个时间单元上能够监听的第一SRS数目可以包括在第一时间单元上能够监听的第一SRS数目以及在第二时间单元上能够监听的第一SRS数目。当第一时间单元为一个slot,第二时间单元为一个持续时间duration(该duration等于X个slot，X为正整数)时，网络设备基于UE1上报的第一能力信息获知UE1在一个时隙中能够监听的第一SRS数目为R，并且在X个时隙中能够监听的第一SRS数目为S。R为大于或等于1的整数，S为大于或等于1的整数。如此，网络设备将第二终端在一个slot中能够发送的第一SRS数目配置为小于或等于R，网络设备将第二终端在X个slot中能够发送的第一SRS数目配置为小于或等于S。比如，UE1在一个时隙中能够监听的第一SRS数目为8，在X个slot中能够发送的第一SRS数目为32，且UE2、UE3复用一个时隙，则网络设备可以将UE2配置成在一个时隙中最多发送2个第一SRS，网络设备将UE3配置成在同一个时隙中最多发送6个第一SRS；并且，网络设备可以将UE2配置成在X个时隙中最多发送8个第一SRS，网络设备将UE3配置成在相同的X个时隙中最多发送24个第一SRS。或者，UE2、UE3不在同一时隙中发送第一SRS，则网络设备可以将UE2配置成在一个时隙中最多发送8个第一SRS，网络设备将UE3配置成在同一个时隙中最多发送8个第一SRS。或者，UE2、UE3不在同样的X个时隙中发送第一SRS，则网络设备可以将UE2配置成在一个时隙中最多发送32个第一SRS，网络设备将UE3配置成在另X个时隙中最多发送32个第一SRS。这样一来，无论UE2、UE3是否复用同一时隙发送第一SRS，在一个时隙中，UE2或UE3最多发送8个第一 SRS，不超出UE1在一个时隙中监听第一SRS数目的上限。无论UE2、UE3是否复用同样的X个时隙发送第一SRS，在X个时隙中，UE2或UE3最多发送32个第一SRS，不超出UE1在X个时隙中监听第一SRS数目的上限。
在另一些实施例中，网络设备可以不基于第一终端上报的第一能力信息配置第二终端的第一SRS。比如，网络设备根据自身决策配置第二终端的第一SRS。
在另一些实施例中，网络设备在用于传输第一SRS(即用于检测CLI的SRS)的符号之前或之后的一个或多个符号上不配置任何数据传输或接收，从而使得终端能进行正确的速率匹配。当然，也可以采取其他方式配置符号，重发或打孔一些比特，进而实现速率匹配。
通常，不同的干扰终端(即第二终端)与被干扰终端(即第一终端)之间的距离不同，所以，不同第二终端的第一SRS到达第一终端的时间可能不对齐。当两个第一SRS的(cyclic shift，CS)间隔较小时，第一终端难以区分这两个第一SRS分别来自哪个第二终端，进而难以判断具体的干扰源。
为了解决上述问题，在另一些实施例中，当两个第二终端的资源相同时，这两个第二终端的第一SRS的根序列不同。两个第二终端的资源相同，可以指两个第二终端的时域资源、频域资源、空域资源中一个或多个相同。如此，可以根据不同根序列区分不同的第一SRS，并判断不同第一SRS分别来自哪一第二终端，进而精确的判断干扰源。
在另一些实施例中，当两个第二终端的资源相同时，这两个第二终端的第一SRS的根序列相同，且这两个第二终端的第一SRS的循环移位之间相差第一偏移量值。
可选的，第一偏移量值可以表示为
Figure PCTCN2020082111-appb-000001
其中，
Figure PCTCN2020082111-appb-000002
为配置第一SRS时最大循环移位的数目。该最大循环移位的数目可以为12或者8，或者别的预设的值。
可选的，第一偏移量值也可以配置为其他格式的参数。在一种方式中，可以基于SRS端口(port)的配置设置第一偏移量值。SRS端口可以理解为发送SRS的天线端口。当SRS端口为不同设置时，第一偏移量值相应变化。在另一种方式中，可以基于符号间隔来设置，还可以基于UE间相对距离来设置。
具体的，第一偏移量值为
Figure PCTCN2020082111-appb-000003
U为可配置的参数，在一个示例中，U表示SRS端口数目，此时，U为正整数。当然，U还可以是与SRS端口数目有关系的参数，比如，可以依据一定运算规则由SRS端口数目得到U。以U为SRS端口数目为例，当SRS端口数目为1时，第一偏移量值为
Figure PCTCN2020082111-appb-000004
当SRS端口数目为2时，第一偏移量值为
Figure PCTCN2020082111-appb-000005
如此，上述当CS之间相差大于或者等于第一偏移量值时，可以保证通过不同的终端设备间距离到达一个接收的终端设备时，不会因为距离差导致CS无法区分。
在另一些实施例中，CS之间相差小于或者等于第二偏移量值。可选的，第二偏移量值可以表示为
Figure PCTCN2020082111-appb-000006
其中V为可配置的参数。上述当CS之间相差小于或者等于第二偏移量值时，可以保证通过不同的终端设备间距离到达一个接收的终端设备时，对CS之间相差的要求不会太高，从而可用的SRS不致太少。
在另一些实施例中，OAM根据第一能力信息配置第二终端的第一SRS。
需要说明的是，本申请实施例对上述S1101-S1105之间的执行顺序不进行限制。示例性的，第一终端可以同时上报各个能力信息。也可以先上报第一能力信息，再上报第二能力信息、第三能力信息。网络设备可以接收某一或多个能力信息后，向第一 终端发送配置信息，也可以先向第一终端下发配置信息，再接收第一终端的某一或多个能力信息。或者即使不接收第一终端的某一或多个能力信息，直接向第一终端下发配置信息。
通常，终端与基站进行通信时，需进行定时同步。也就是说，基站需知道在哪一接收时机接收来自终端的信息，或者在哪一时机向终端发送信息，终端也需知道在哪一时机接收来自基站的信息，或则在哪一时机向基站发送信息，以便于在正确的收发时机收发信息。参见图4，以基站收发下行消息的时间为基准时间，UE1的上行发送相对于基准时间应提前d1/c，UE1的下行接收应滞后d2/c，d1为UE1与基站1之间的距离。类似的，UE2的上行发送和下行接收时机可参考UE1的相应时机。以便于UE和基站之间的定时同步。
现有技术中，针对CLI中的定时同步，提出两种解决方法。解决方法一，终端在传输物理上行共享信道(physical uplink shared channel，PUSCH)的同时传输第一SRS，即传输第一SRS的定时提前量(timing advance，TA)等于传输PUSCH的TA值。如此，虽然能够进行上下行定时同步，但是，传输PUSCH和传输第一SRS可能占用相同的时频资源，终端很可能无法正确解调PUSCH，丢失有用的数据。解决方法二，这种方法中，需假设UE1、UE2的距离很近，因此可以忽略图1a所示中的距离d。UE2在基准时间d2/c之后发送第一SRS，UE1在基准时间d1/c检测该第一SRS。在该方法中，UE2将发送时间滞后d2/c，相当于用于传输第一SRS的符号也会相应后移。比如，原本通过第一个时隙中的第7个符号传输第一SRS，现在，需要将发送时间滞后d2/c，相应的，可能通过下一时隙(第二个)的第一个符号传输第一SRS。但是，该第二个时隙的第一个符号很可能已被配置成用于传输PUSCH，导致在该符号上第一SRS和PUSCH的冲突，不利于终端解调PUSCH。
为了解决上述技术问题，本申请实施例还提供一种定时同步方法，参见图5，该定时同步方法包括如下步骤：
S501、第二终端获取发送第一探测参考信号SRS的第一资源。
其中，第一资源与第二终端的地理位置信息存在对应关系。多个地理位置信息，分别对应多个第一资源。第二终端处于不同地理位置，第二终端发送第一SRS的第一资源不同。作为一种可能的实现方式，可以将预设地理区域划分为P(P为正整数)个子区域。其中，每一子区域对应一个地理位置信息。地理位置信息比如可以为子区域的标识、代码、编号等。P可以预配置在终端中，或者由网络设备配置。不同地理位置信息对应不同的资源。
上述第一资源可以是时域资源、频域资源、空域资源、码域资源等。本申请实施例不对第一资源的类型做具体限制。对应于不同地理位置信息，第二终端发送第一SRS的资源不同，可以指通过不同时域资源发送第一SRS，也可以指通过不同频域资源发送第一SRS，或者，通过不同空域资源发送第一SRS，也可以指通过不同码域资源发送第一SRS。以资源为时域资源举例，第二终端位于子区域1时，通过一个时隙中的第6个符号发送第一SRS，第二终端位于子区域2时，通过一个时隙中的第7个符号发送第一SRS。以资源为空域资源为例，第二终端位于子区域1时，通过第一天线端口发送第一SRS，第二终端位于子区域2时，通过第二天线端口发送第一SRS。
可选的，第一资源为预配置在终端中的资源，即第一资源为基于第二终端地理位置信息的预配置资源。比如，终端中预配置有资源与地理位置信息的对应关系。如此，第二终端发送第一SRS时，可以查询该对应关系，并根据该对应关系确定在当前地理位置应该使用哪一资源发送第一SRS。
可选的，第二终端从网络设备接收SRS配置消息，该SRS配置消息用于指示第二终端的地理位置信息对应的第一资源。具体的，网络设备通过如下至少一种方式向第二终端指示第一资源。
方式1：SRS配置消息为广播消息。具体的，网络设备周期性发送广播消息。第二终端从网络设备接收广播消息，并根据广播消息确定在当前地理位置发送第一SRS可使用的资源。其中，广播消息携带地理位置信息与资源的对应关系。该对应关系可以包括多个地理位置信息和多个资源的关系，比如，对应关系可以为{地理位置信息1-资源1；地理位置信息2-资源2；…地理位置Q-资源Q}。当然，对应关系还可以是其他格式，比如表格格式。本申请实施例对对应关系的格式不做限定。第二终端接收并存储该对应关系。后续，第二终端需发送第一SRS时，查询该对应关系，以获知当前地理位置对应的资源，并使用对应的资源发送第一SRS。
方式2：第二终端发送第一SRS之前，向网络设备发送SRS资源请求，SRS资源请求用于请求发送第一SRS的第一资源。
可选的，在方式2中，第二终端的SRS资源请求包括第二终端的当前地理位置信息。如此，网络设备根据第二终端的当前地理位置信息，为第二终端配置对应的第一资源，并向第二终端发送SRS配置消息，用于指示第二终端的当前地理位置对应的第一资源。
或者，第二终端发送的SRS资源请求也可以不携带第二终端的当前地理位置信息。网络设备在接收到来自第二终端的SRS资源请求之后，先确定第二终端的当前地理位置，再基于该当前地理位置为第二终端配置第一资源。
其中，第二终端可以采用如下方法获取第二终端的当前地理位置：网络设备向第二终端发送第二参考信号，第二终端在接收到第二参考信号之后，获取第二参考信号对应的第二RSRP，并基于第二RSRP获取第二终端的地理位置信息。其中，第二RSRP用于表征第二参考信号到达第二终端的接收功率。或者，第二终端在接收到第二参考信号之后，获取第二参考信号对应的第二RSRQ，并基于第二RSRQ获取第二终端的地理位置信息。其中，第二RSRQ用于表征第二参考信号到达第二终端的信号质量。
网络设备可以采用如下方法获取第二终端的当前地理位置：网络设备向第二终端发送第二参考信号，第二终端在接收到第二参考信号之后，获取第二参考信号对应的第二RSRP，并向网络设备发送该第二RSRP。如此，网络设备基于接收的第二RSRP获取第二终端的地理位置信息。或者，第二终端在接收到第二参考信号之后，获取第二参考信号对应的第二RSRQ，并向网络设备发送该RSRQ。如此，网络设备基于接收的第二RSRQ获取第二终端的地理位置信息。
当然，第二终端或网络设备还可以采用其他方式确定第二终端的当前地理位置，本申请对此不进行限制。
S502、第二终端使用第一资源发送第一SRS。
相应的，第一终端从第二终端接收第一SRS。
可选的，第一终端还可以向网络设备发送第四能力信息(也可称为测量精度能力)。第四能力信息用于表征对测量结果的精度要求。精度要求高，即规定第一终端对第一SRS的测量结果在预设偏差范围内，精度要求低，即第一终端对第一SRS的测量结果可以不在预设偏差范围内。容易理解的是，若精度要求高，网络设备基于第四能力信息进行配置，比如网络设备指示第一终端执行如下S503以及后续流程，以调整接收定时(timing)，在正确的时机接收第一SRS，以保证对第一SRS的测量结果更为准确。若精度要求低，则第一终端可以不执行如下调整接收定时的步骤。
当然，第一终端还可以基于对测量结果的精度要求自身判断是否执行如下S503以及后续流程。
S503、第一终端根据第一资源确定定时偏移。
作为一种可能的实现方式，参见图6，S503可具体实现为如下步骤：
S5031、第一终端根据第一资源获取第二终端的地理位置信息。
其中，上文已指出，第一资源与地理位置信息存在对应关系。基于此对应关系，第一终端可以根据发送第一SRS的第一资源确定第二终端的地理位置信息。该对应关系可以预配置在第一终端中。比如，对应关系可以为{地理位置信息1-资源1；地理位置信息2-资源2；…地理位置Q-资源Q}。当然，该对应关系可以存储在除上述网络设备(比如基站)外的其他设备中，第一终端在需查询对应关系时，从存储该对应关系的设备中获取该对应关系。本申请实施例对第一终端获取第二终端地理位置信息的具体实现方式不做限定。在一个示例中，第一终端监听到来自第二终端的第一SRS，该第一SRS在一个时隙的第6个符号上发送，则第一终端根据对应关系，可以确定第二终端的地理位置。
S5032、第一终端根据自身的地理位置信息和第二终端的地理位置信息获取第一距离，第一距离为第一终端和第二终端之间的距离。
其中，第一终端获取自身的地理位置信息的方式可参见上述第二终端获取自身的地理位置信息的方式，这里不再赘述。
S5033、第一终端根据第一距离获取定时偏移。
参见图4，以第一终端为UE1，第二终端为UE2为例，UE1与UE2之间的距离为d。则定时偏移可以采用如下公式计算：t＝d/c，其中，t为定时偏移，c为无线电信号的传播速度，/为除法运算符。
S504、基于定时偏移调整接收第一SRS的时间。
也就是，在调整接收时机时，能够考虑第一终端和第二终端之间的第一距离的影响。可选的，参见图4，UE2在基准时间之前d2/c发送第一SRS，UE1在基准时间之后(d1-d)/c检测该第一SRS。UE2的发送时机和UE1的检测(接收)时机相差(d2+d1-d)/c。
当然，UE2还可以在其他时机发送第一SRS，此时，只要UE的接收时机与UE2的发送时机相差(d2+d1-d)/c，就能够保证UE1测量的第一SRS的信号强度接近该第一SRS的信号峰值，从而提升测量结果的准确性。
S505、在调整后的接收第一SRS的时间接收第一SRS。
本申请实施例提供的通信方法，第一终端基于某一第二终端的第一SRS的第一资源，确定定时偏移，并基于该定时偏移，调整接收该第一SRS的时间。如此，第一终端在调整后的时间接收该第一SRS。由于能够在较为准确的时间接收第一SRS，所以，测出的第一SRS的信号强度可能更接近该第一SRS的信号峰值，使得针对第一SRS的测量结果更为准确。
