具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例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各种通信系统，例如：宽带码分多址移动通信系统(wideband code division multiple access，WCDMA)，演进的全球陆地无线接入网络(evolved universal terrestrial radio access network，E-UTRAN)系统，下一代无线接入网络(next generation radio access network，NG-RAN)系统，长期演进(long term evolution，LTE)系统，全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信系统，未来的第五代(5th Generation，5G)系统，如新一代无线接入技术(new radio access technology，NR)，及未来的通信系统，如6G系统等。
本申请实施例描述的业务场景(或应用场景)是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
另外，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或实现方案不应被解释为比其它实施例或实现方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)终端(terminal)，包括向用户提供语音和/或数据连通性的设备，例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该 终端可以包括用户设备(user equipment，UE)、无线终端、移动终端、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端的计算机，便携式、袖珍式、手持式、计算机内置的移动装置，智能穿戴式设备等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位系统(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，在本申请实施例中，该终端还可以是可穿戴设备等。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端，车载终端例如也称为车载单元(on-board unit，OBU)。
2)网络设备，例如包括接入网(access network，AN)设备，例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端通信的设备，或者例如，一种V2X技术中的网络设备为路侧单元(road side unit，RSU)。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。RSU可以是支持V2X应用的固定基础设施实体，可以与支持V2X应用的其他实体交换消息。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G NR系统中的下一代节点B(next generation node B，gNB)或者也可以包括云接入网(cloud radio access network，CloudRAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，或者6G等任何新一代系统中的基站，本申请实施例并不限定。
3)通用用户网络接口(user to network interface universal，Uu)，简称Uu口，又称之为Uu接口，是终端和网络设备之间用于无线通信的接口，终端通过Uu口接入到通信系统中，Uu口的主要功能为广播、寻呼、以及RRC连接的处理。
4)蜂窝链路，终端和网络设备通过Uu接口通信的链路。本申请中，蜂窝链路(cellular link)也可以替换为主链路(main link)，或UU链路，或非侧行链路等。
5)侧行链路(sidelink)，也可以称为边链路或副链路等，本申请实施例对此名称不 作限定。在V2X场景中，侧行链路为两V2X终端之间的直连链路连接，V2X终端为具有V2X功能的终端。
6)SL传输，两个V2X终端在侧行链路上的数据传输，称为SL传输。
两个V2X终端在进行SL传输之前，可以建立侧行链路连接。比如，作为发起方的V2X终端向网络设备发送建立侧行链路连接的请求，网络设备如果同意该V2X终端建立侧行链路连接，则向该V2X终端发送建立侧行链路连接的配置信息，该V2X终端根据网络设备发送的配置信息与另一V2X终端建立侧行链路连接。本申请中，侧行链路也可以替换为边链路，或辅链路(supplementary link)。
7)资源，也可以称之为传输资源，包括时域资源、频域资源、时频资源或空间域资源等中的任意一种或多种的组合。
需要说明的是，两个V2X终端建立侧行链路之后，可以在一定的传输资源上进行SL传输，资源选择方式有两种。比如，由网络设备为终端分配SL传输资源。再比如，终端自主的选择SL传输资源；其中，终端可以在配置的资源池中根据干扰检测选择SL传输资源。本申请中“配置”可以为网络设备通过信令发送或者预配置，其中网络设备通过信令发送包括通过RRC信令，MAC信令或物理层信令中的至少一种发送给终端装置；预配置包括OAM配置，或者预先设置在终端/网络设备中。
8)时间单元，时域资源包括一个或多个时间单元，时间单元可以是无线帧、子帧、时隙、符号等。其中，一个无线帧可以包括多个子帧，一个子帧可以包括一个或多个时隙(slot)，一个时隙可以包括至少一个符号(symbol)。或者，一个无线帧可以包括多个时隙，一个时隙可以包括至少一个符号。
在5G NR中，一个时隙可以由用作下行传输的符号、用作灵活的符号、用作上行传输的符号等其中的至少一个组成，这样时隙的构成称为不同的时隙格式(slot format，SF)，时隙格式最多可能有256种。其中，灵活的符号可以用作保护间隔GP。图1示例性的给出了几种可能的时隙格式。由图1可知，一个时隙中的每个符号可以是上行(uplink，UL)，下行(downlink，DL)和未知(unknown)3种状态，记为UL(U)/DL(D)/X。X称为unknown或灵活(flexible)(flexible符号，也可称为F符号)，终端在对应的符号上既不收也不发。可选的，终端在X符号上可以进行相应的检测。
另外，由图1可见，不同的时隙格式的时隙包括的上行符号个数、下行符号个数、灵活符号个数、或保护间隔符号个数中的任一项可以不一样。
时隙可以有不同的时隙类型，不同的时隙类型包括的符号个数不一样，如迷你时隙(mini slot)包含小于7个符号，普通时隙(slot)包含7个符号或14个符号等。根据子载波间隔不同，每个符号长度可以不同，因此时隙长度可以不同。
在5G NR中，还引入了时隙聚合技术，即网络设备可以将多个时隙分配给同一个终端用于传输数据。比如，终端可以在分配的多个时隙上进行上行数据调度，比如物理上行共享信道(physical uplink shared channel，PUSCH)的调度，也可以在分配的多个时隙上进行下行数据调度，比如物理下行共享信道(physical Downlink Shared CHannel，PDSCH)的调度等。
需要说明的是，本申请实施例涉及的时隙可以为上述任一种时隙。
9)在5G NR中，支持半静态的时隙格式配置。其中，半静态的信令指示是通过无线资源控制(radio resource control，RRC)信令通知一个时间段或一个周期中的时隙格式(可 以是一个或多个slot的时隙格式)，比如，通过RRC指令指示一个或多个时隙中每个符号是UL，DL或unknown状态。
半静态的信令包含两种，一种是针对小区(cell-specific)的，也就是配置给某小区中的所有终端，某小区中的所有终端都接收这个信令；另一种是针对特定UE的，也就是配置给某小区中的某个终端，只有该终端接收这个信令，这也称之为专用信令(dedicated signaling)。
在5G NR中，也支持动态的时隙格式配置。比如，通过下行控制信息(downlink control information，DCI)信令通知一段周期上的时隙格式(可以是一个或多个slot的时隙格式)，该DCI信令称为动态时隙格式指示(slot format indicator，SFI)，可以通过DCI2_0下发。
10)SFI指示，即蜂窝链路上的SFI指示，SFI指示可以用于指示至少一个时隙中的一个或多个符号的传输方向为下行，上行或者灵活，以便终端在SFI指示所指示的时隙或符号上进行数据收发。
此外，NR中预定义多个时隙的若干种符号状态组合，该组合所在的表称之为UE特定表格(UE specific table)，比如，基站可以配置(比如通过RRC配置)一组一个或多个时隙上的时隙格式组合，其中可以使用组合的序号entry ID来指示具体的时隙格式组合，比如，表格中entry ID1至少第一组时隙格式组合。该表格中最大数目的entry ID数为512，每个entry ID对应的时隙格式组合包括的最大slot个数为256。基站可以通过DCI信令动态指示一个或多个时隙上的时隙格式组合。DCI信令的格式可以是DCI2_0，DCI1_0等。
举例说明，参见图2所示，为entry ID与时隙格式组合的示意图。网络设备可以通过RRC信令下发一个表格，该表格中包括配置的entry ID以及与每个entry ID对应的时隙格式组合,横轴为该组合中不同的slot，纵轴为entry index(entry ID),比如，entry ID为entry 1的时隙格式组合为S1至Sm，m小于256，即256中时隙格式中的1到m种时隙格式的组合。
然后，网络设备可以通过不同的动态SFI指示终端对应配置为该表格中某个entry ID对应的时隙格式组合，比如，网络设备向终端发送DCI，该DCI中携带entry ID，终端可以在图2所示的表格中确定与SFI指示中携带entry ID对应的时隙格式组合。
作为一种示例，DCI是承载在GC-PDCCH信道上，DCI中携带的每个SFI index为一个时隙格式组合entry ID,总共可以承载16个cell的SFI index，参见图3所示。网络设备可以配置终端每隔一定时间去检测GC-PDCCH，接收SFI的信息指示，这个时间周期称为monitor period。
因此，通用的SFI指示还可以用于指示多个时隙的若干种符号状态组合，即指示entry ID。
11)侧行链路时隙配置(SL slot configuration)，用于指示侧行链路上的时隙格式(Sidelink slot format,SL slot format)。该侧行链路时隙配置指示可以类似NR技术。比如，侧行链路时隙配置指示包含半静态和动态的侧行链路时隙配置。具体的，半静态的侧行链路时隙配置通过RRC信令通知一个时间段或一个周期中的时隙格式，即SL，UU接口的UL，UU接口的DL或UU接口的灵活(flexible)状态中的任意一种或多种的组合。所述时隙格式为一个或多个时隙的时隙格式。也可以说，侧行链路时隙配置用于指示发送或接收SL数据的一个或多个时隙，即在与该SL时隙格式配置对应的时隙上接收或发送SL数据。
半静态的信令包括两种，一种为cell-specific的半静态的信令，即针对整个cell配置(例如，表示为TDD-UL-DL-ConfigCell-SL或者TDD-UL-DL-SL-ConfigCell)，也就是小区中的所有终端都接收这个配置；另一种为UE-specific的半静态的信令，即针对特定UE，可以为 UE dedicated signaling(例如，表示为TDD-UL-DL-ConfigDedicated-SL或者TDD-UL-DL-SL-ConfigDedicated)。示例性的，参见图4所示，第一行所列为NR通用的cell-specific的半静态的时隙格式配置，第二行所列为在NR通用的cell-specific的半静态的时隙格式配置基础上，将其中的X或U符号进一步标识为用于SL传输的S符号，即SL-cell-specific TDD configuration。当配置为第二行所示的SL-cell-specific TDD configuration时，可以进一步指示起始符号以及持续符号个数，使得在起始符号以及持续符号个数上的X或U符号被覆盖为S符号，用作SL传输。当配置为第二行所示的SL-cell-specific TDD configuration时，可以进一步指示或者起始符号以及终结符号，使得在起始符号以及终结符号之间的X或U符号被覆盖为S符号，用作SL传输。
可选的，上述示例中cell-specific的半静态的SL时隙格式配置也可以替换为UE dedicated signaling指示的UE specific半静态的SL时隙格式配置。
本申请中，侧行链路时隙配置也可以称之为侧行链路(SL)时隙格式配置。即，SL时隙格式配置包含上述cell-specific的半静态的SL时隙格式配置和上述UE-specific的半静态的SL时隙格式配置。本申请中“特定的(specific)”也可以替换为“专用的(dedicated)”。
在IAB场景中，侧行链路时隙配置相应的可以替换为接入/回传链路时隙(格式)配置。相应的，接入/回传链路时隙(格式)配置cell-specific的半静态的接入/回传链路时隙格式配置和上述UE-specific的半静态的接入/回传链路时隙格式配置。具体的，半静态的接入/回传链路时隙配置通过RRC信令通知一个时间段或一个周期中的时隙格式，即接入链路(access link)，回传链路(backhaul link)的UL/DL/灵活(flexible)状态中的任意一种或多种的组合。所述时隙格式为一个或多个时隙的时隙格式。也可以说，接入/回传链路时隙配置用于指示发送或接收接入链路/回传链路数据的一个或多个时隙，即在与该接入/回传链路时隙格式配置对应的时隙上接收或发送接入链路/回传链路数据。
具体的，动态的侧行链路时隙配置可以表示为SL-SFI或SFI-SL。在5G-NR中，在通用的SFI(上述的SFI指示)通知的基础上，还可以通知侧行链路上的SFI，即SL-SFI。示例性的，参见图4所示，第一行所列为NR通用的SFI，第二行所列为在NR通用的SFI基础上，将其中的X或U符号进一步标识为用于SL传输的S符号，即SL-SFI。当配置为第二行所示的SL-SFI时，可以进一步指示起始符号以及持续符号个数，使得在起始符号以及持续符号个数上的X或U符号被覆盖为S符号，用作SL传输。当配置为第二行所示的SL-SFI时，可以进一步指示或者起始符号以及终结符号，使得在起始符号以及终结符号之间的X或U符号被覆盖为S符号，用作SL传输。
需要说明的是，SL-SFI也可以用于指示一个时隙或一个时隙上至少一个符号，或者，指示至少一个时隙中的至少一个符号，还可以用于指示多个时隙的若干种符号状态组合，即指示entry ID，以便终端在DCI所指示的时隙或符号上进行数据传输。
进一步，S还可以标识侧行链路上的上行传输(sidelink transmission，简称SL Tx)或侧行链路上的下行接收(sidelink reception，SL Rx)状态，在此不多赘述。
12)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“至少一个”，可理解为一个或多个，例如理解为一个、两个或更多个。例如，包括至少一个，是指包括一个、两个或更多个，而且不限制包括的是哪几个。例如，包括A、B和C中的至少一个，那么包括的可以是A、B、C，A和B，A和C，B和C，或A和B和C。同理，对于“至少一种” 等描述的理解，也是类似的。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如第一时域资源和第二时域资源，只是为了区分不同的时域资源，并不是限制这两个时域资源的优先级或重要程度等。
下面介绍本申请实施例所涉及的应用场景。
本申请实施例提供的通信方法可以应用在车与外界(vehicle-to-everything，V2X)场景，其中，V2X具体又包括车与车(Vehicle-to-Vehicle，V2V)、车与行人(Vehicle-to-Pedestrian，V2P)、车与路侧基础设施(Vehicle-to-Infrastructure，V2I)、车与应用服务器(Vehicle-to-Network，V2N)四种应用场景。V2V指的是基于LTE的车辆间通信；V2P指的是基于LTE的车辆与人(包括行人、骑自行车的人、司机、或乘客)的通信；V2I指的是基于LTE的车辆与路边装置(RSU)的通信，V2N指的是基于LTE的车辆与基站/网络的通信。
参见图5，为本申请实施例提供的一种应用场景的示意图。图5所示的应用场景为V2N场景，该场景中包括网络设备、终端1和终端2，终端1(或终端2)和网络设备可以通过蜂窝链路和侧行链路(sidelink)进行通信。
需要说明的是，图5中的网络设备例如为接入网设备，例如基站。其中，接入网设备在不同的系统对应不同的设备，例如在第四代移动通信技术(the 4th generation，4G)系统中可以对应eNB,在5G系统中对应5G中的接入网设备，例如gNB。其中，图5中的终端是以车载终端或车为例，但本申请实施例中的终端不限于此。
由于网络设备和终端之间的数据传输较为复杂，包括侧行链路上的数据和蜂窝链路上的数据可能会占用相同的传输资源，本申请实施例提供通信方法，以解决侧行链路和蜂窝链路的资源冲突的问题。
当然，本申请实施例还可以适用于其它应用场景，比如，综合接入和回传链路(Integrated access and backhaul,IAB)场景。在IAB场景中，终端和网络设备之间存在接入链路，网络设备之间存在回传链路，因此整个系统中既有终端和网络设备之间的接入链路，又有网络设备之间的回传链路。当一个网络设备面临回传链路上的发送和接入链路上的接收时，存在冲突；同样，当一个网络设备面临回传链路上的接收和接入链路上的发送时，也存在冲突。或者，当一个网络设备既要在回传链路上发送，又要在接入链路上发送时，存在冲突。或者，当一个网络设备既要在回传链路上接收，又要在接入链路上接收时，存在冲突。上述发送/接收都值在相同资源上。因此，本申请实施例提供的通信方法也可以解决IAB场景中接入链路和回传链路上数据收发的资源冲突问题。
由于，网络设备和终端都涉及不同通信链路的数据的收发，所以网络设备和终端都会面临资源冲突的问题，下述以终端装置为例说明，需要说明的是，终端装置可以是终端，也可以是网络设备，即下文中的方法流程可以由终端执行，也可以由网络设备执行。应理解，下文中的终端装置可以是终端或者网络设备的整机、或者是终端或者网络设备中能够执行下述方法流程的一个部件或多个部件的组合、或者是终端或者网络设备中能够实现下述方法流程的芯片等，本申请实施例不作限定。
需要说明的是，本申请实施例提供的通信方法还可以解决不同通信系统之间的信息传输的资源冲突问题。由于，终端和网络设备通信时，可以支持多通信系统的数据通信。因此，当一个终端面临第一通信系统上的链路的数据收发和第二通信系统上的链路的数据的收发时，可能存在资源冲突问题。具体而言，包括多种情况：比如，当一个终端面临第一通信系统上的蜂窝链路的数据收发和第二通信系统上的蜂窝链路的数据的收发时，可能存在资源冲突问题；或者，当一个终端面临第一通信系统上的侧行链路的数据收发和第二通信系统上的侧行链路的数据的收发时，可能存在资源冲突问题；或者当一个终端面临第一通信系统上的蜂窝链路的数据收发和第二通信系统上的侧行链路的数据的收发时，可能存在资源冲突问题；或者，当一个终端面临第一通信系统上的侧行链路的数据收发和第二通信系统上的蜂窝链路的数据的收发时，可能存在资源冲突问题；或者，当一个终端面临第一通信系统上的接入链路的数据收发和第二通信系统上的接入链路的数据的收发时，可能存在资源冲突问题；或者，当一个终端面临第一通信系统上的回传链路的数据收发和第二通信系统上的回传链路的数据的收发时，可能存在资源冲突问题；当一个终端面临第一通信系统上的接入链路的数据收发和第二通信系统上的回传链路的数据的收发时，可能存在资源冲突问题；或者，当一个终端面临第一通信系统上的回传链路的数据收发和第二通信系统上的接入链路的数据的收发时，可能存在资源冲突问题。本申请中数据收发为数据发送或接收。
其中，第一通信系统可以是LTE系统，第二通信系统可以是5G系统；或者，第一通信系统是5G系统，第二通信系统是LTE系统；或者，第一通信系统可以是5G系统，第二通信系统可以是5G系统；第一通信系统可以是LTE系统，第二通信系统可以是LTE系统。当然，其中5G系统也可以替换为新无线(new radio,NR)系统，本申请实施例不作限定。
本申请中，当第一通信系统和第二通信系统中，一者是LTE系统，另一者是5G系统时，LTE系统的数据收发的优先级可以高于5G系统的数据收发的优先级，因为，考虑到LTE系统的配置没有5G系统的配置灵活，所以LTE的优先级高可以保证LTE的业务优先得到保障。当然，5G系统的数据收发的优先级也可以高于LTE系统的数据收发的优先级，应理解，只要涉及到不同通信系统中数据收发的情况，均可以通过本申请提供的技术方案解决不同通信系统的数据收发存在的资源冲突问题。
本申请中，当第一链路和第二链路中，一者是接入链路，另一者是回传时，回传链路的数据收发的优先级可以高于接入链路的数据收发的优先级，因为，考虑到回传链路的数据收发产生的影响会大于接入链路上的数据收发对于整个系统的影响，所以回传链路的优先级高可以保证系统的关键业务优先得到保障。当然，接入链路的优先级也可以高于回传链路的优先级，只要涉及到不同通信链路中数据收发的情况，均可以通过本申请提供的技术方案解决不同通信链路的数据收发存在的资源冲突问题。
当然，具体到第一链路的第一信息和第二链路的第二信息而言，还需要根据第一信息和第二信息两者之间的优先级进行考虑。通常，PRACH/同步信息会大于普通的PDSCH/PUSCH传输等。具体可以参考下述场景中以蜂窝链路和侧行链路为示例时的第一信息和第二信息的数据优先级比较。下述根据第一信息和第二信息的数据优先级比较进行的是否收发第一信息/第二信息以及是否取消第一信息/第二信息，同样适用于上述不同的通信系统，不同的链路类型，都可以做扩展，属于本申请所涵盖内容，不再赘述。
需要说明的是，下文的介绍以V2X场景为例，且下文以时域资源进行举例说明，但时 域资源可以替换为时频资源，也可以替换为上述资源中的任何一种或多种的组合。
接下来结合附图介绍本申请实施例提供的技术方案。
实施例一：
参见图6所示，为本申请实施例提供的通信方法的流程图，该方法可以由图5所示应用场景中的终端或者网络设备执行，下面以终端执行该方法为例进行介绍。如图6所示，该方法包括：
S601：终端获取第一指示信息，所述第一指示信息用于指示所述终端装置在第一时域资源上发送或接收第一链路的第一信息。
需要说明的是，如前述内容可知，终端的资源可以是网络设备分配的，也可以是终端根据预先配置所确定的。如果是网络设备分配的，那么S601包含两种情况，情况1：终端从网络设备接收第一指示信息(参见图6中的S601a)；情况2：终端也可以从其它终端处接收第一指示信息，比如网络设备将第一指示信息发送给其它终端，由其它终端将该第一指示信息转发给终端(参见图6中的S601b1-S601b2)。如果终端根据预先配置所确定的，那么S601可以是终端根据预先配置确定第一指示信息，或者说第一指示信息是预配置的。因为本申请实施例不限定第一指示信息是从网络设备或其它终端获取的，还是预先配置的，所以图6中，S601a、S601b1-S601b2以虚线表示。
作为一种示例，第一指示信息可以是调度信息，即第一指示信息用于指示终端在第一时域资源上接收或发送第一信息。其中，调度信息可以是下行授权信息或者上行授权信息。具体而言，第一指示信息是下行授权信息时，该下行授权信息用于指示终端在第一时域资源上接收第一信息；第一指示信息是上行授权信息时，该上行授权信息用于指示终端在第一时域资源上发送第一信息。作为一种示例，第一指示信息也可以指示第一时域资源，该第一时域资源用于接收或发送第一链路的第一信息。作为另一种示例，第一指示信息可以是高层信令，即RRC信令。
S602：终端获取第二指示信息，所述第二指示信息用于指示所述终端装置在第二时域资源上接收或发送第二链路上的第二信息。
需要说明的是，本申请实施例不限定S601和S602之间的执行顺序，可以先执行S601，再执行S602，或者可以先执行S602，再执行S601。
应理解，S602也可也包含两种情况，情况1：终端从网络设备接收第二指示信息(参见图6中的S602a)；情况2：终端也可以从其它终端处接收第二指示信息，比如网络设备将第二指示信息发送给其它终端，由其它终端将该第二指示信息转发给终端(参见图6中的S602b1-S602b2)。如果终端根据预先配置所确定的，那么S602可以是终端根据预先配置确定第二指示信息，或者说第二指示信息是预配置的。因为本申请实施例不限定第二指示信息是从网络设备或其它终端获取的，还是预先配置的，所以图6中，S602a、S602b1-S602b2以虚线表示。
因此，第一时域资源和第二时域资源可以都是网络设备分配的，也可以都是终端根据预先配置所确定的，或者第一时域资源是网络设备分配的，而第二时域资源是终端根据预先配置所确定的，或者第一时域资源是终端根据预先配置所确定的，而第二时域资源是网络设备分配的，本申请实施例不作限定。
本申请中终端根据预先配置所确定的，可以理解为预先配置给该终端；网络设备根据预先配置所确定的，可以理解为预先配置给该网络设备。其中，预先配置包括通过运维管 理(operation administration/and management,OAM)配置。比如，预先配置给终端，可以理解为，OAM预先配置给终端的；预先配置给网络设备，可以理解为OAM预先配置给网络设备的。
示例性的，第二指示信息可以是调度信息，即第二指示信息用于指示终端在第二时域资源上接收或发送第二链路的第二信息；第二指示信息也可以指示第二时域资源，该第二时域资源用于接收或发送第二链路的第二信息；第二指示信息还可以是高层信令，即RRC信令。
需要说明的是，第一时域资源可以是时域资源，也可以是时频资源，第二时域资源可以是时域资源，或者时频资源，本申请实施例不作限定。
以第一时域资源和第二时域资源均是时域资源为例，那么第一时域资源或第二时域资源可以是时隙，也可以是符号，下面介绍第一时域资源和第二时域资源的多种情况。
举例来说，第一时域资源为至少一个第一时隙，第二时域资源为至少一个第二时隙；或者，第一时域资源为至少一个第一符号，第二时域资源为至少一个第二符号；或者，第一时域资源为至少一个第一时隙中的M个符号，M为大于等于1的整数，第二时域资源为至少一个第二时隙中的N个符号，N为大于等于1的整数；或者，第一时域资源为至少一个第一时隙，第二时域资源为至少一个第二符号，或者，第一时域资源为至少一个第一符号，第二时域资源为至少一个第二时隙。
第一时域资源为至少一个第一子帧，第二时域资源为至少一个第二子帧；或者，第一时域资源为至少一个第一子帧，第二时域资源为至少一个第二时隙；或者，第一时域资源为至少一个第一子帧，第二时域资源为至少一个第二符号；或者，第一时域资源为至少一个第一时隙，第二时域资源为至少一个第二子帧；或者，第一时域资源为至少一个第一符号，第二时域资源为至少一个第二子帧。
S603：确定第一时域资源和第二时域资源重叠，或者，第一时域资源和第三时域资源重叠，所述第三时域资源是所述第二时域资源之前或者之后的时域资源。
关于第三时域资源：
若第三时域资源可以是第二时域资源之前的时域资源，比如第三时域资源的终止点可以是第二时域资源的起始点，或者早于第二时域资源的起始点，第三时域资源可以包括第一收发转换时间，该第一收发转换时间包括发送到接收的转换时间或者接收到发送的转化时间。可选的，第三时域资源的起始点可以是第一收发转换时间的起始点，或早于第一收发转换时间的起始点，第三时域资源的终止点可以是第一收发转换时间的终止点，或者晚于第一收发转换时间的终止点。总之，第三时域资源所占的时间长度大于或等于或大于等于第一转换时间所占的时间长度，以确保转换完成。这是因为，若第二时域资源之前的第三时域资源和第一时域资源重叠，那么在重叠的资源上是进行收发转换还是进行第一信息的收发是冲突的，可能会导致无法正常收发第一信息或者无法正常完成收发转换(将会影响第二时域资源上的数据的收发)，这种情况下，终端取消在第二时域资源上的收发第二信息，而是在第一时域资源上收发第一信息，以保证第一信息的正常发送或接收。
若第三时域资源是第二时域资源之后的时域资源，比如第三时域资源的起始点可以是第二时域资源的终止点，或者第三时域资源的起始点晚于第二时域资源的终止点。第三时域可以包括第二收发转换时间，该第二收发转换时间包括发送到接收的转换时间或者接收到发送的转化时间。可选的，第三时域资源所占的时间长度大于或等于或大于等于第二转 换时间所占的时间长度，以确保转换完成。
第三时域资源可以为一个或多个符号，或者小于一个符号的长度，或者一个预定义的值，本申请实施例不作限定。其中，第三时域资源单位可以为毫秒ms或微秒us。
需要说明的是，第一时域资源和第二时域资源重叠可以是第一时域资源和第二时域资源全部重叠或者部分重叠；第一时域资源和第三时域资源重叠也可以是第一时域资源和第三时域资源全部重叠或部分重叠。
下面以第一时域资源和第二时域资源重叠为例。
举例来说，第一时域资源是至少一个第一时隙，第二时域资源是至少一个第二时隙时，若第一时域资源和第二时域资源中的至少一个时隙或者至少一个符号重叠，则第一时隙资源和第二时隙资源重叠。
再比如，第一时域资源是至少一个第一符号，第二时域资源是至少一个第二符号，则第一时域资源和第二时域资源中的至少一个符号重叠时，则第一时域资源和第二时域资源重叠。
再比如，第一时域资源是至少一个第一时隙中的M个符号，第二时域资源是至少一个第二时隙中的N个符号，则第一时域资源中的M个符号和第二时域资源中的N个符号中的至少一个符号重叠时，则第一时域资源和第二时域资源重叠。
再比如，第一时域资源是至少一个第一时隙，第二时域资源是至少一个第二符号，则第一时域资源和第二时域资源中的至少一个符号重叠时，则第一时域资源和第二时域资源重叠。
再比如，第一时域资源是至少一个第一符号，第二时域资源是至少一个第二时隙，则第一时域资源和第二时域资源中的至少一个符号重叠时，则第一时域资源和第二时域资源重叠。
需要说明的是，由于第一时域资源和第二时域资源的情况较多，所以第一时域资源和第二时域资源的重叠不再一一举例，同样的，第三时域资源的情况也较多，第一时域资源和第三时域资源重叠也不再一一举例。
S604：终端在第一时域资源上接收或发送第一信息。
在该实施例中，第一链路的第一信息的优先等级大于第二链路的第二信息的优先等级，所以当第一时域资源和第二时域资源重叠，或者第一时域资源和第三时域资源重叠时，终端在第一时域资源上接收或发送第一链路的第一信息。
需要说明的是，终端可以向网络设备发送第一信息或者从网络设备接收第一信息，也可以向其它终端发送第一信息，或从其它终端接收第一信息，所以S604存在多种情况，比如情况1：参见图6中的S604a，即终端向网络设备发送第一信息或从网络设备接收第一信息，情况2；参见图6中的S604b，终端向其它终端发送第一信息，或者终端从其它终端接收第一信息，图6中以情况1为例，所以S604b以虚线表示。
S605：终端取消在第二时域资源上接收或发送第二信息。
由于第一链路的第一信息的优先等级大于第二链路的第二信息的优先等级，所以当第一时域资源和第二时域资源重叠，或者第一时域资源和第三时域资源重叠时，终端可以取消在第二时域资源上接收或发送第二链路的第二信息。
可选的，本申请实施例不限定S604和S605之间的执行顺序。可选的，本申请实施例也可以为S604和S605之间只选择一者执行或者都执行。
如前述内容可知，本申请提供的通信方法可以适用于多种应用场景，以V2X场景为例，第一链路是蜂窝链路时，第二链路是侧行链路，或者第一链路是侧行链路，第二链路是蜂窝链路。以IAB场景为例，第一链路是接入链路，第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路。以终端支持多通信系统为例，第一链路可以是第一通信系统的蜂窝链路或回传链路或侧行链路或接入链路，第二链路可以是第二通信系统中的蜂窝链路或回传链路或侧行链路或接入链路(具体包含多种情况，比如第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路)，其中，第一通信系统可以是LTE系统，第二通信系统可以是5G系统，或者第一通信系统是5G系统，第二通信系统是LTE系统；或者，第一通信系统可以是LTE系统，第二通信系统可以是LTE系统，或者，第一通信系统可以是5G系统，第二通信系统可以是5G系统。需要说明的是，上述描述适用于本申请中任何实施例。
本申请中，当第一链路是接入链路，第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路时，所述第一信息/所述第二信息不需要是受限于侧行链路上所传输的控制信息，数据信息以及反馈信息中的任何一种。同样，当第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路时，所述第一信息/所述第二信息也不需要是受限于侧行链路上所传输的控制信息(PSCCH)，数据信息(PSSCH)以及反馈信息(PSFCH)中的任何一种。例如，所述第一信息/所述第二信息包括如下信息中的至少一种信息：物理下行共享信道(physical DL shared channel，PDSCH)、物理上行共享信道(physical UL shared channel，PUSCH)、物理下行控制信道(physical DL control channel，PDCCH)、物理上行控制信道(physical UL control channel，PUCCH)、响应参考信号(sounding reference signal，SRS)、信道状态信息参考信号(channel state information-reference signal SL-CSI-RS)、反馈信道(physical hybird ARQ indicator channel，PHICH)、同步信息。类似的地方不再一一描述，即第一信息/第二信息可以是去掉SL这种特定限制的对应信息，例如，对PSCCH去掉SL这种特定限制的可以对应的为PUCCH/PDCCH。
本申请中预设时域资源全部重叠或部分重叠可以是一个或多个符号重叠，或者小于一个符号的时间长度的重叠(也就是说，重叠的资源可以是一个或多个符号，也可以是小于一个符号的时间长度)。另外，本申请中第一时域资源和第二时域资源全部重叠或部分重叠也可以是一个或多个符号重叠，或者小于一个符号的时间长度的重叠；本申请中第一时域资源和第三时域资源全部重叠或部分重叠也可以是一个或多个符号重叠，或者小于一个符号的时间长度的重叠。总之，本申请中的任何两个时域资源的重叠，都可以是一个或多个符号重叠，或者小于一个符号的时间长度的重叠。
下面以V2X场景为例，分两种情况介绍。
第一种情况，第一链路是蜂窝链路，第二链路是侧行链路。
示例1：
终端获取第一指示信息，第一指示信息用于指示终端在第一时域资源上发送第一链路(蜂窝链路)的第一信息，所述第一信息包括如下信息中的至少一种：物理随机接入信道(physical random access channel，PRACH)，超高可靠低时延通信(ultra reliable and low latency communications，URLLC)数据，免授权(grant free)数据，高服务质量(quality of service，QoS)数据。
其中，免授权数据通常指grant free的调度所指示的数据传输，包括网络设备通过半静态的信令配置的数据传输资源，和/或网络设备通过半静态的信令配置的数据传输资源并且需要动态信令激活该数据传输资源。高QoS数据包括根据包优先级(ProSe Per-Packet Priority,PPPP)，或QoS索引(5QoS index，5QI)，或者任何QoS准则所判断的PPPP较高的数据，或者5QI较高的数据等。
终端获取第二指示信息，第二指示信息用于指示终端在第二时域资源上接收或发送第二链路(侧行链路)的第二信息。所述第二信息包括如下信息中的至少一种信息：物理边链路共享信道(physical sidelink shared channel，PSSCH)、物理边链路控制信道(physical sidelink control channel，PSCCH)、侧行链路响应参考信号(sidelink sounding reference signal，SL-SRS)、侧行链路信道状态信息参考信号(sidelink channel state information-reference signal，SL-CSI-RS)、物理边链路反馈信道(physical sidelink feedback channel，PSFCH)、侧行链路同步信息块(SL-SS blocks)。
示例1中，若蜂窝链路和侧行链路上的数据收发存在资源冲突的问题，解决该资源冲突问题的方式可以有多种，下面列举两种方式。
第一种方式，若第一时域资源和第二时域资源重叠，终端在所述第一时域资源发送第一链路(蜂窝链路)的第一信息，和/或，所述终端取消在所述第二时域资源上接收或发送第二链路(侧行链路)的第二信息。
举例来说，参见图7所示，以第一时域资源是一个时隙中的M个符号为例。终端获取第一指示信息，第一指示信息用于指示终端在第一时域资源上发送PRACH。若终端获取第二指示信息，第二指示信息用于指示终端在第二时域资源(一个时隙中的N个符号)上收发SL数据。第一时域资源和第二时域资源存在重叠，则终端可以取消第二时域资源上收发SL数据，在第一时域资源上发送PRACH。
也就是说，当用于发送PRACH的第一时域资源与用于收发SL数据的第二时域资源重叠(全部或部分重叠)时，PRACH的优先等级大于SL数据的优先等级，终端先考虑优先级较高的PRACH，取消优先级较低的SL数据的收发。
需要说明的时，上面的例子中，第一指示信息可以是随机接入信道配置索引(RACH-ConfigurationIndex)，或者是包含于RACH-ConfigurationIndex中的信息，本申请实施例不作限定。其中，RACH-ConfigurationIndex可以包含于物理随机信号公共配置消息(RACH-ConfigCommon)中。
第二指示信息可以是SL时隙格式配置。该SL时隙格式配置包括半静态的cell specific和/或UE specific的时隙格式配置。
再例如，以第一时域资源是一个时隙中的M个符号为例。终端获取第一指示信息，第 一指示信息用于指示终端在第一时域资源上发送URLLC数据。终端获取第二指示信息，第二指示信息用于指示终端在第二时域资源上收发SL数据，如果第一时域资源和第二时域资源重叠，则终端取消在第二时域资源上收发SL数据，在第一时域资源上发送URLLC数据。其中，第二指示信息可以是SL时隙格式配置，或者Uu口的下行控制信息(downlink control information，DCI)、侧行链路控制信息(sidelink control information，SCI)或者SFI-SL等，或者第二指示信息是携带于DCI、SCI或者SFI-SL中的信息。所述SL时隙格式配置可以是网络设备发送的。
可选的，上面的例子中，URLLC数据可以是包括PUSCH重复的数据，例如由PDCCH激活的PUSCH重复。该PDCCH包含UL授权信息，例如为type 2的UL授权。
总结来说，对于用于指示进行任何PUSCH重复的一个或多个符号,终端不期望接收到第二指示信息指示所述一个或多个符号中任何一个符号是用于SL数据收发的。其中，所述PUSCH重复由PDCCH激活，该PDCCH包含UL授权信息，例如为type 2的UL授权。
需要说明的是，本申请实施例中涉及“收发”包括接收或发送中任何一种。
在第一种方式中，第一时域资源被指示用于发送蜂窝链路的第一信息，第二时域资源被指示用于收发侧行链路的第二信息，若第一时域资源和第二时域资源重叠时，第一信息的优先级大于第二信息的优先级。
第二种方式，若所述第一时域资源和第三时域资源(所述第二时域资源之前或之后的预设时域资源)重叠，所述终端在所述第一时域资源发送所述第一链路(蜂窝链路)的第一信息，和/或，所述终端取消在所述第二时域资源上接收或发送第二链路(侧行链路)的第二信息。
举例来说，参见图8所示，以第一时域资源是一个时隙中的M个符号为例，第一时域资源被指示用于终端发送PRACH。若终端获取第二指示信息，用于指示在第二时域资源(一个时隙上的N个符号)上接收或发送SL数据。若第二时域资源之前的预设时域资源(图8中以第二时域资源之前的2个预设符号为例)与第一时域资源重叠，则PRACH的优先级大于SL数据的优先级，终端先考虑优先级较高的PRACH，取消优先级较低的SL数据的收发。第二时域资源之前或之后的预设时域资源可以为P个符号，P为正整数，例如，图8所示P为2，以第二时域资源之前的2个预设符号为例。
可选的，上述第二时域资源之前的预设时域资源也可以替换为第一时域资源之前或之后的预设时域资源，即第三时域资源可以替换为第一时域资源之前或之后的预设时域资源，举例来说，继续以第一时域资源是一个时隙中的M个符号为例，第一时域资源被指示用于终端发送PRACH。若终端获取第二指示信息，用于指示在第二时域资源(一个时隙上的N个符号)上接收或发送SL数据。若第一时域资源之前的预设时域资源与第二时域资源重叠，PRACH的优先级大于SL数据的优先级，终端先考虑优先级较高的PRACH，取消优先级较低的SL数据的收发。
应理解，第二时域资源之前或之后的预设时域资源，或，第一时域资源之前或之后的预设时域资源，都可以为P个符号，P为正整数。第二时域资源之前或之后的预设时域资源，或，第一时域资源之前或之后的预设时域资源，也可以为GAP。
其中，第二指示信息可以是UE特定的半静态SL时隙格式配置(TDD-UL-DL-ConfigDedicated-SL或者TDD-UL-DL-SL-ConfigDedicated)，也可以是cell specific的半静态SL时隙格式配置(TDD-UL-DL-ConfigCell-SL或者 TDD-UL-DL-SL-ConfigCell)，或者Uu口的DCI，SCI或SFI-SL，本申请实施例不作限定。
示例2：

其中，同步信息、coreset比如是用于Type0-PDCCH common search space(CSS)set的信息。
终端获取第二指示信息，第二指示信息用于指示终端在第二时域上接收或发送第二链路(侧行链路)的第二信息。所述第二信息包括如下信息中的至少一种信息：物理边链路共享信道(physical sidelink shared channel，PSSCH)、物理边链路控制信道(physical sidelink control channel，PSCCH)、侧行链路响应参考信号(sidelink sounding reference signal，SL-SRS)、侧行链路信道状态信息参考信号(channel state information-reference signal SL-CSI-RS)、物理边链路反馈信道(physical sidelink feedback channel，PSFCH)、SL同步信息。
这种情况下，解决资源冲突的方式可以有多种，下面列举两种。
第一种方式，若第一时域资源和第二时域资源重叠，终端在所述第一时域资源接收第一链路(蜂窝链路)的第一信息，和/或，所述终端取消在所述第二时域资源上接收或发送第二链路(侧行链路)的第二信息。
举例来说，终端接收网络设备发送的第一指示信息，该第一指示信息用于指示终端在第一时域资源上接收SS/PBCH blocks，若终端获取第二指示信息，该第二指示信息用于指示终端在第二时域资源上收发SL数据，若第一时域资源和第二时域资源重叠，则SS/PBCH blocks的优先等级大于SL数据的优先等级，终端可以取消第二时域资源上的SL数据的收发，在第一时域资源上接收SS/PBCH blocks。
其中，第一指示信息可以是网络设备通过SystemInformationBlockType1中的ssb-PositionsInBurst或者通过ServingCellConfigCommon中的ssb-PositionsInBurst指示给终端，本申请实施例不作限定。
再例如，终端获取第一指示信息，该第一指示信息用于指示终端在第一时域资源上接收同步信息/CORSET，若终端获取第二指示信息，第二指示信息用于指示终端在第二时域资源上接收或发送SL数据，则同步信息/CORSET的优先等级大于SL数据的优先等级，终端可以取消在第二时域资源上收发SL数据，在第一时域资源上接收/CORSET。
其中，第二指示信息可以是UE特定的半静态SL时隙格式配置(TDD-UL-DL-ConfigDedicated-SL或者TDD-UL-DL-SL-ConfigDedicated)，也可以是cell specific的半静态SL时隙格式配置(TDD-UL-DL-ConfigCell-SL或者TDD-UL-DL-SL-ConfigCell)，或者Uu口的DCI，SCI或SFI-SL，本申请实施例不作限定。

可选的，上述第二时域资源之前的预设时域资源也可以替换为第一时域资源之前的预设时域资源。举例来说，若第一时域资源之前的预设时域资源与第二时域资源重叠，则SS blocks、PBCH blocks的优先级大于SL数据的优先级，终端先考虑优先级较高的PRACH，取消优先级较低的SL数据的收发。所述第一时域资源之前的预设时域资源可以为P个符号，P为正整数。

本申请中UE特定的，即为针对特定UE的；cell specific即为针对cell的，或cell共有的(cell common)。
第二种情况，第一链路是侧行链路，第二链路是蜂窝链路。

实施例二：
参见图9所示，为本申请实施例提供的通信方法的流程图，如图9所示，该流程包括：
S901：终端获取第一指示信息，所述第一指示信息用于指示所述终端在第一时域资源上发送或接收第一链路的第一信息；
S902：所述终端获取第二指示信息，所述第二指示信息用于指示所述终端在第二时域资源发送或接收第二链路的第二信息；
需要说明的是，关于第一指示信息、第二指示信息、第一信息、第二信息、第一时域资源和第二时域资源的描述可以参见图6所示的实施例，在此不重复赘述。
S903：确定第一时域资源和第二时域资源重叠。
可选的，终端执行完S903之后，可以确定第一时长，在第一时长之后，或者之内执行S904和/或S905。
可选的，第一时长可以是第一信息的第一准备时长，也可以是第二信息的第二准备时长，还可以是第一准备时长和第二准备时长之间的最小值。其中，第一准备时长和第二准备时长可以相等或不等。
需要说明的是，本申请实施例中的准备时间(或准备时长)也可以替换为处理时间(或处理时长)，为根据处理能力确定的一个时长。
以第一时长是第一信息的准备时长为例，该准备时间为接收到第一指示信息的最后时刻开始进行计算，即第一时长的起始点是接收到第一指示信息的最后时刻(时刻也可以称为时间点)，第一时长的终止点是第一时域资源的起始点或者早于第一时域资源的起始点。在第一时长内，终端准备第一信息的接收或发送工作。第一时长可以为一个或多个符号，也可以为小于一个符号的值，具体取决于终端的处理能力。
S904：在第二时域资源上接收或发送第二信息。
应理解，图9所示的实施例中，第二信息为不同信息的情况下，向终端发送第二信息的设备或接收第二信息的设备(终端的对侧)可以是网络设备或其他终端设备，所以S904b以虚线表示。
S905：停止在第一时域资源上接收或发送第一信息。
需要说明的是，当第一时域资源和第二时域资源重叠时，终端可以等待第一时长，即在第一时长之后在第二时域资源发送或接收第二信息，和/或，在第一时长之后停止在所述第一时域资源上接收或发送所述第一信息；当然，终端也可以无需等待第一时长，在所述第一时长之内在第二时域资源发送或接收第二信息，和/或，在第一时长之内停止在所述第一时域资源上接收或发送所述第一信息。
在该实施例中，第二链路的第二信息的优先等级大于第一链路的第一信息的优先等级，所以当第一时域资源和第二时域资源重叠时，终端在第二时域资源上接收或发送第二链路的第二信息，取消在第一时域资源上接收或发送第一链路的第一信息。
可选的，终端停止(或者是取消)第一时长之后在第一时域资源上接收或发送所述第一信息，可以是停止(或者是取消)在第一时长之后在所述第一时域资源与第二时域资源的重叠资源上接收或发送所述第一信息。

同样，该实施例提供的通信方法可以适用于多种应用场景，以V2X场景为例，第一链路是蜂窝链路时，第二链路是侧行链路，或者第一链路是侧行链路，第二链路是蜂窝链路。以IAB场景为例，第一链路是接入链路、第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路。以终端支持多通信系统为例，第一链路可以是第一通信系统的蜂窝链路或回传链路或侧行链路或接入链路，第二链路可以是第二通信系统中的蜂窝链路或回传链路或侧行链路或接入链路(具体包含多种情况，比如第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路)，其中，第一通信系统可以是LTE系统，第二通信系统可以是5G系统，或者第一通信系统是5G系统，第二通信系统是LTE系统；或者，第一通信系统可以是LTE系统，第二通信系统可以是LTE系统，或者，第一通信系统可以是5G系统，第二通信系统可以是5G系统。
本申请中，当第一链路是接入链路，第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路时，所述第一信息/所述第二信息不需要是受限于侧行链路上所传输的控制信息，数据信息以及反馈信息中的任何一种。同样，当第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路时，所述第一信息/所述第二信息也不需要是受限于侧行链路上所传输的控制信息(PSCCH)，数据信息(PSSCH)以及反馈信息(PSFCH)中的任何一种。例如，所述第一信息/所述第二信息包括如下信息中的至少一种信息：物理下行共享信道(physical DL shared channel，PDSCH)、物理上行共享信道(physical UL shared channel，PUSCH)、物理下行控制信道(physical DL control channel，PDCCH)、物理上行控制信道(physical UL control channel，PUCCH)、响应参考信号(sounding reference signal，SRS)、信道状态信息参考信号(channel state information-reference signal SL-CSI-RS)、反馈信道(physical hybird ARQ indicator channel，PHICH)、同步信息。类似的地方不再一一描述， 即第一信息/第二信息可以是去掉SL这种特定限制的对应信息，例如，对PSCCH去掉SL这种特定限制的可以对应的为PUCCH/PDCCH。

实施例三：
参见图12所示，为本申请实施例提供的通信方法的流程示意图，如图12所示，该流程包括：
S1201：终端获取第一指示信息，所述第一指示信息用于指示第一时域资源的数据传输方向。
时域资源的传输方法包括上行(UL)、下行(DL)或灵活(F)。
如前述内容可知，一个时域资源可以是一个或多个时隙，一个时隙中的不同符号是下行、上行或灵活。
示例性的，图12中步骤S1201有多种实现方式，例如步骤S1201a，即网络设备向终端发送第一指示信息；或者，步骤S1201b1和步骤S1201b2，即网络设备通过其他终端向所述终端发送第一指示信息。

示例性的，图12中步骤S1202有多种实现方式，例如步骤S1202a，即网络设备向终端发送第二指示信息；或者，步骤S1202b1和步骤S1202b2，即网络设备通过其他终端向所述终端发送第二指示信息。
需要说明的是，第一指示信息、第二指示信息，第一时域资源、第二时域资源、第一信息和第二信息的相关描述可以参见图6所示的实施例，在此不再重复赘述。
S1203：确定第一时域资源和第二时域资源重叠。
S1204：在所述第一时域资源的传输方向为第一链路的上行或第一链路的下行的情况下，所述终端取消在所述第二时域资源上接收或发送所述第二链路的第二信息。
在该实施例中，第一链路的第一信息的优先等级大于第二链路的第二信息的优先等级，当第一时域资源的传输方向是上行或下行时，若第一时域资源和第二时域资源重叠，则终端取消在第二时域资源上收发第二链路的第二信息。
S1205：在第一时域资源的数据传输方向为灵活的情况下，所述终端在所述第二时域资源上发送或接收所述第二链路的第二信息。
需要说明的是，在该实施例中，终端可以向网络设备发送第二信息或者从网络设备接收第二信息，也可以向其它终端发送第二信息，或从其它终端接收第二信息，在此不多赘述。
当第一时域资源的传输方向是灵活时，若第一时域资源和第二时域资源重叠，则终端在第二时域资源上收发第二链路的第二信息。
同样，该实施例提供的通信方法可以适用于多种应用场景，以V2X场景为例，第一链路是蜂窝链路时，第二链路是侧行链路，或者第一链路是侧行链路，第二链路是蜂窝链路。以IAB场景为例，第一链路是接入链路、第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路。以终端支持多通信系统为例，第一链路可以是第一通信系统的蜂窝链路或回传链路或侧行链路或接入链路，第二链路可以是第二通信系统中的蜂窝链路或回传链路或侧行链路或接入链路(具体包含多种情况，比如第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路)，其中，第一通信系统可以是LTE系统，第二通信系统可以是5G系统，或者第一通信系统是5G系统，第二通信系统是LTE系统；或者，第一通信系统可以是LTE系 统，第二通信系统可以是LTE系统，或者，第一通信系统可以是5G系统，第二通信系统可以是5G系统。
本申请中，当第一链路是接入链路，第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路时，所述第一信息/所述第二信息不需要是受限于侧行链路上所传输的控制信息，数据信息以及反馈信息中的任何一种。同样，当第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路时，所述第一信息/所述第二信息也不需要是受限于侧行链路上所传输的控制信息(PSCCH)，数据信息(PSSCH)以及反馈信息(PSFCH)中的任何一种。例如，所述第一信息/所述第二信息包括如下信息中的至少一种信息：物理下行共享信道(physical DL shared channel，PDSCH)、物理上行共享信道(physical UL shared channel，PUSCH)、物理下行控制信道(physical DL control channel，PDCCH)、物理上行控制信道(physical UL control channel，PUCCH)、响应参考信号(sounding reference signal，SRS)、信道状态信息参考信号(channel state information-reference signal SL-CSI-RS)、反馈信道(physical hybird ARQ indicator channel，PHICH)、同步信息。类似的地方不再一一描述，即第一信息/第二信息可以是去掉SL这种特定限制的对应信息，例如，对PSCCH去掉SL这种特定限制的可以对应的为PUCCH/PDCCH。
下面以V2X场景为例，且以第一链路为蜂窝链路，第二链路为侧行链路为例，进行说明。
示例1：
第一指示信息用于指示所述终端在第一时域资源上接收第一链路(蜂窝链路)的下行数据，第二指示信息用于指示终端在第二时域资源发送或接收第二链路(侧行链路)的第二信息。这种情况下，若所述第一时域资源和所述第二时域资源重叠，所述终端取消在所述第二时域资源上接收或发送第二信息。
需要说明的是，资源配置包括配置资源的传输方向，和/或配置资源用于收发的信息。以一个符号为例，该符号可以一方面被指示传输方向为UL，另一方面通过高层信令指示该符号具体传输什么上行数据。因此，示例1中，第一指示信息用于指示所述终端在第一时域资源上接收第一链路(蜂窝链路)的下行数据可以包括两种情况：
情况1，第一指示信息是用于指示第一传输资源的传输方向(比如第一指示信息是时隙格式配置，SL时隙格式配置，或SFI)，假设第一指示信息用于指示第一时域资源上的符号的状态为DL，这样的话，终端获取到第二指示信息之后，取消第二时域资源上接收或发送侧行链路的第二信息。
举例来说，第一时域资源的状态为DL，第二时域资源的状态为侧行链路，若第一时域资源和第二时域资源重叠，说明第一时域资源和第二时域资源存在上下行传输方向的重叠，这种情况下，终端取消在第二时域资源上的侧行链路的数据传输。第一时域资源的状态为DL，具体为第一时域资源的状态为蜂窝链路的DL。第二时域资源的状态为侧行链路，具体为第二时域资源的状态为侧行链路的传输或接收。
总结来说，用于指示侧行链路上的半静态的侧行链路时隙格式配置(包括TDD-UL-DL-SL-ConfigCell和/或TDD-UL-DL-SL-ConfigDedicated)、时隙格式的SFI-SL、 UU interface以及DCI所指示的传输方向不应该与UU interface的DCI所指示的传输方向冲突；因为，UU interface的DCI指示蜂窝链路的符号的传输方向，而半静态的侧行链路时隙格式配置、SFI-SL、DCI5A或者新的用于调度侧行链路传输的DCI用于指示侧行链路的传输方向。
或者，半静态的侧行链路时隙格式配置(包括TDD-UL-DL-SL-ConfigCell和/或TDD-UL-DL-SL-ConfigDedicated)、或SFI-SL所指示的传输方向不应该与TDD-UL-DL-ConfigurationCommon、TDD-UL-DL-ConfigDedicated或SFI TDD配置所指示的传输方向冲突；因为，半静态的侧行链路时隙格式配置(包括TDD-UL-DL-SL-ConfigCell和/或TDD-UL-DL-SL-ConfigDedicated)、或SFI-SL指示的是侧行链路的符号的传输方向，而TDD-UL-DL-ConfigurationCommon、TDD-UL-DL-ConfigDedicated、SFI TDD指示的是蜂窝链路的符号的传输方向。
再例如，如果一个UE被调度在SL的多个slots接收PDSCH，如果第二指示信息指示对于多个slots中的一个slot,至少有一个symbol被调度用于PDSCH接收的被配置为上行符号，说明资源重叠但传输方向冲突，UE取消接收该slot中的PDSCH。需要说明的是，该例子中，无论多slot调度的scheduled PDSCH/PUSCH在SL是通过slot聚合或者半静态的SPS。其中，第二指示信息可以是TDD-UL-DL-ConfigurationCommon,或TDD-UL-DL-ConfigDedicated或半静态的侧行链路时隙格式配置。
情况2，第一指示信息是用于指示在第一时域资源上接收蜂窝链路的下行数据(比如第一指示信息是DCI)，这样的话，终端获取到第二指示信息之后，取消第二时域资源上收发侧行链路的第二信息。
需要说明的是，在该实施例中，不限定蜂窝链路的下行数据具体是什么信息，比如可以是PDSCH、PDCCH等。
示例2：
第一指示信息用于指示所述终端在第一时域资源上发送第一链路(蜂窝链路)的上行数据，第二指示信息用于指示终端在第二时域资源发送或接收第二链路(侧行链路)的第二信息。这种情况下，若所述第一时域资源和所述第二时域资源重叠，所述终端取消在所述第二时域资源上接收或发送第二信息；
应理解，示例2中，第一指示信息用于指示所述终端在第一时域资源上发送第一链路(蜂窝链路)的上行数据可以包括多种情况：
情况1：第一指示信息用于指示在第一时域资源上的传输方向为UL，这样的话，终端获取第二指示信息之后，取消第二时域资源上收发侧行链路的第二信息。
举例来说，第一时域资源的状态为DL，第二时域资源的状态为侧行链路，若第一时域资源和第二时域资源重叠，说明第一时域资源和第二时域资源存在上下行传输资源的重叠及方向冲突，这种情况下，终端取消在第二时域资源上的侧行链路的数据传输。第一时域资源上的传输方向为UL，具体为第一时域资源上的传输方向为蜂窝链路UL；第二时域资源的状态为侧行链路，具体为第二时域资源的状态为侧行链路的发送或接收。
再例如，如果一个UE被调度在SL的多个slots发送PUSCH并且如果TDD-UL-DL-ConfigurationCommon,或TDD-UL-DL-ConfigDedicated,指示对于多个slots中的一个slot,至少一个symbol被调度用于PUSCH发送的被配置为下行符号，则UE不发送该slot中的PUSCH。其中，无论多slot调度的scheduled PDSCH/PUSCH在SL是通过slot聚 合或者半静态的SPS。
情况3：第一指示信息是用于指示在第一时域资源上发送蜂窝链路的上行数据的，这样的话，终端获取第二指示信息之后，取消第二时域资源上收发第二信息。
需要说明的是，在该实施例中，不限定上行数据具体是什么信息，比如可以是PUSCH、PUCCH等。
参见图13所示，第一时域资源包括一个时隙中的M个符号，M个符号为UL，第二时域资源包括一个时隙中的N个符号，N个符号为DL，第一时域资源和第二时域资源重叠，即M个符号与N个符号中有至少一个符号重叠，则终端取消在第二时域资源上接收侧行链路的第二信息。
因此，总结示例1和示例2可知，对于一个slot中的一系列符号，如果第一指示信息指示该系列符号为DL/UL，UE不期望检测到第二指示信息，该第二指示信息用于指示该系列符号用于sidelink上的数据的传输/接收。其中，第一指示信息可以是TDD-UL-DL-ConfigurationCommon,or TDD-UL-DL-ConfigDedicated,或SFI。第二指示信息可以是SFI-SL，或TDD-UL-DL-SL-ConfigDedicated/TDD-UL-DL-ConfigDedicated-SL/TDD-UL-DL-SL-ConfigCommon，或者是SFI-SL中的SFI-index或TDD-UL-DL-SL-ConfigDedicated/TDD-UL-DL-ConfigDedicated-SL/TDD-UL-DL-SL-ConfigCommon中的SFI-index。
在另一些实施例中，对于一个slot中的一系列符号，如果由TDD-UL-DL-ConfigurationCommon或TDD-UL-DL-ConfigDedicated或SFI,指示为DL/UL，UE不期望检测到SFI-SL，或者TDD-UL-DL-SL-ConfigDedicated/TDD-UL-DL-ConfigDedicated-SL/TDD-UL-DL-SL-ConfigCommon，该SFI-SL中的SFI-index或TDD-UL-DL-SL-ConfigDedicated/TDD-UL-DL-ConfigDedicated-SL/TDD-UL-DL-SL-ConfigCommon中指示该slot中的该系列符号为灵活。
示例3：
若所述第一时域资源和所述第二时域资源重叠，且所述第一时域资源的传输方向为灵活，所述终端在所述第二时域资源上发送或接收第二信息。
需要说明的是，第一时域资源的传输方向为灵活，说明该第一时域资源的传输方向可以改变，所以第一时域资源和第二时域资源重叠时，终端可以在第二时域资源上收发侧行链路的第二信息。
实施例四：
如前述内容可知，蜂窝链路上的符号包括UL/DL/F三种状态，在系统(比如5G NR)中仅包括蜂窝链路的场景下，对于F符号，终端是不进行数据收发的，但是对于包含蜂窝链路和侧行链路的场景下，终端在F符号上不进行数据的收发需要满足如下条件：
终端没有获取指示信息，该指示信息用于指示终端在该F符号上进行SL数据的收发；或者终端获取到了指示信息，但该指示信息并未指示终端在该F符号上进行SL数据的收发。其中，所述指示信息可以是半静态SL时隙格式配置、SCI或UU interface的DCI或SFI-SL等。
对于蜂窝链路上符号通过高层信令配置为上行发送，终端若要进行上行发送，需要满足如下条件：
1、终端获取第一指示信息，该第一指示信息用于指示该符号是UL。第一指示信息可以是DCI。
2、终端没有获取指示信息，该指示信息用于指示终端在该符号上进行SL数据的收发；或者终端获取到了指示信息，但该指示信息并未指示终端在该符号上进行SL数据的收发。其中，所述指示信息可以是半静态的SL时隙格式配置、SCI或SFI-SL等。
对于蜂窝链路上符号通过高层信令配置为下行接收，终端若要进行下行接收，需要满足如下条件：
1、终端获取第一指示信息，该第一指示信息用于指示该符号是DL。第一指示信息可以是DCI。
2、终端没有获取指示信息，该指示信息用于指示终端在该符号上进行SL数据的收发；或者终端获取到了指示信息，但该指示信息并未指示终端在该符号上进行SL数据的收发。其中，所述指示信息可以是半静态SL时隙配置、SCI或SFI-SL等。
对于通过高层信令配置的在第一时域资源上进行PDCCH检测，若终端在第一时域资源上进行PDCCH检测，需要满足如下条件：
终端没有获取指示信息，该指示信息用于指示终端在与第一时域资源重叠的资源上进行SL数据的收发；
或者，终端获取到了指示信息，但该指示信息并未指示终端在与第一时域资源重叠的资源上进行SL数据的收发。其中，所述指示信息可以是半静态SL时隙配置、UU interface的DCI或SCI或SFI-SL等。
SL数据包括PSCCH、PSSCH、SL-SRS、SL-CSI-RS、PSFCH等。
实施例五：
在上述的各个实施例中，介绍终端获取第一指示信息和第二指示信息之后，若第一指示信息指示的第一时域资源和第二指示信息指示的第二时域资源重叠时，如何处理。在该实施例中，终端获取第一指示信息，第一指示信息用于指示终端在第一时域资源上接收或发送第一链路的第一信息；这种情况下，第一时域资源中的至少一个符号不会被配置用于第二链路的第二信息。
具体而言，第一时域资源被配置为收发第一链路的第一信息，那么终端或网络设备不会配置第一时域资源中的至少一个符号用于第二链路的第二信息的收发。换言之，在上述的各个实施例中介绍一个时域资源既被配置为用于第一链路的第一信息的收发，而第一时域资源中的一个或多个符号又被配置为用于第二链路的第二信息的收发后，终端如何处理。在该实施例中，一个符号不会被既配置为用于第一链路的第一信息的收发，又配置为第二链路的第二信息的收发。
举例来说，对于一个slot中的一系列符号，如果网络设备通过第一指示信息指示给UE用于进行SS/PBCH blocks的接收，UE不期望检测到半静态的SL时隙格式配置、或SFI-SL，该SFI-SL中的SFI-index域指示该slot中的一系列symbols用于sidelink传输。其中，第一指示信息可以是SystemInformationBlockType1中的ssb-PositionsInBurst或者ServingCellConfigCommon中的ssb-PositionsInBurst。
其中，UE不期望检测到半静态SL时隙配置或SFI-SL，包括终端或网络设备不会再将已 配置为用于进行SS/PBCH blocks的接收的一系列符号再配置为用于SL数据的发送。
若对于一个符号已经被配置用于第一链路的第一信息的收发，一旦该符号再被配置为用于第二链路的第二信息的收发，那么终端可以基于第一信息和第二信息的优先等级，确定收发哪一个信息。前面的实施例中已经介绍过，在此不重复赘述。
举例来说，对于一个slot中的一系列符号，如果网络设备通过第一指示信息指示给UE用于进行SS/PBCH blocks的接收，若终端获取第二指示信息，该第二指示信息用于指示在第二时域资源上传输sidelink调度的PSSCH，PSCCH,PSHICH，若第一时域资源和第二时域资源重叠，则UE取消在该slot中传输sidelink调度的PSSCH，PSCCH,PSHICH。其中，第一指示信息可以是SystemInformationBlockType1中的ssb-PositionsInBurst或者ServingCellConfigCommon中的ssb-PositionsInBurst。
再例如，对于一个slot中的一系列符号，如果网络设备通过第一指示信息指示给UE用于进行SS/PBCH blocks的接收，若终端获取第二指示信息，第二指示信息用于指示在第二时域资源上传输RS(包括SL-CSI-RS,SRS等)，若第一时域资源和第二时域资源重叠，则UE取消在该slot中传输RS(包括SL-CSI-RS,SRS等)。
再例如，对于一个slot中的一系列符号，如果网络设备通过第一指示信息指示给终端(UE)用于进行UU口的第一URLLC数据的收发，若终端获取第二指示信息，第二指示信息用于指示在第二时域资源上传输SL的第二URLLC数据，若第一时域资源和第二时域资源重叠，则UE根据第一URLLC数据和第二URLLC数据的优先级高低确定是否取消第一URLLC数据/第二URLLC数据。例如，当第一URLLC数据优先级高于第二URLLC数据时，UE在第一时域资源上进行第一URLLC数据的收发，UE在第二时域资源上取消第二URLLC数据。又例如，当第一URLLC数据优先级低于第二URLLC数据时，UE在第一时域资源上取消第一URLLC数据，UE在第二时域资源上传输第二URLLC数据。
实施例六：
当V2X场景中考虑侧行链路的同步信号(sidelink SSblock，SL-SSB)的传输时,用于传输S-SSB的资源可能和用于传输蜂窝链路上的数据的资源冲突，可以采用如下的冲突解决方案：
1、SL-SSB的优先等级大于高层信令配置的蜂窝链路上的数据的收发。其中，通过高层信令配置的蜂窝链路上的数据的发送包括：PRACH、URLLC数据。
举例来说，SL-SSB的优先等级可以高于PRACH的优先等级。因此，终端获取第一指示信息，该第一指示信息用于传输终端在第一时域资源上发送PRACH时，若终端获取第二指示信息，第二指示信息用于指示终端在第二时域资源上发送SL-SSB，若第一时域资源和第二时域资源重叠，终端取消在第一时域资源上发送PRACH，而在第二时域资源上发送SL-SSB。这种情况下，终端可以丢弃第一指示信息，和/或丢弃待发送的PRACH。
再例如，SL-SSB的优先等级可以高于或低于UU interface的URLLC的优先等级。以SL-SSB的优先等级高于URLLC的优先级为例，终端获取第一指示信息，该第一指示信息用于指示终端在第一时域资源上发送URLLC数据时，若终端获取第二指示信息，第二指示信息用于指示终端在第二时域资源上发送SL-SSB，若第一时域资源和第二时域资源重叠，终端取消在第一时域资源上发送URLLC数据，而在第二时域资源上发送SL-SSB。这种情况下，终端可以丢弃第一指示信息，和/或丢弃待发送的URLLC数据。

实施例八：
参见图14所示，为本申请实施例提供的通信方法的流程示意图，如图14所示，该流程包括：
S1401：终端获取第一指示信息，所述第一指示信息用于指示所述终端在第一时域资源上接收或发送第一链路的第一信息。

终端满足调度限制的条件，可以是终端调度限制适用或者有调度限制。
S1405：若不满足，停止基于第二链路的第二信息进行测量。
终端不满足调度限制的条件，可以是终端调度限制不适用，或者没有调度限制。
该实施例提供的通信方法可以适用于多种应用场景，以V2X场景为例，第一链路是蜂窝链路时，第二链路是侧行链路，或者第一链路是侧行链路，第二链路是蜂窝链路。以IAB场景为例，第一链路是接入链路、第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路。以终端支持多通信系统为例，第一链路可以是第一通信系统的蜂窝链路或回传链路或侧行链路或接入链路，第二链路可以是第二通信系统中的蜂窝链路或回传链 路或侧行链路或接入链路(具体包含多种情况，比如第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的蜂窝链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的蜂窝链路，第二链路是第二通信系统的侧行链路，或者，第一链路是第一通信系统的侧行链路，第二链路是第二通信系统的蜂窝链路)，其中，第一通信系统可以是LTE系统，第二通信系统可以是5G系统，或者第一通信系统是5G系统，第二通信系统是LTE系统；或者，第一通信系统可以是LTE系统，第二通信系统可以是LTE系统，或者，第一通信系统可以是5G系统，第二通信系统可以是5G系统。
本申请中，当第一链路是接入链路，第二链路是回传链路，或者第一链路是回传链路，第二链路是接入链路时，所述第一信息/所述第二信息不需要是受限于侧行链路上所传输的控制信息，数据信息以及反馈信息中的任何一种。同样，当第一链路是第一通信系统的接入链路，第二链路是第二通信系统的接入链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的接入链路，第二链路是第二通信系统的回传链路，或者，第一链路是第一通信系统的回传链路，第二链路是第二通信系统的接入链路时，所述第一信息/所述第二信息也不需要是受限于侧行链路上所传输的控制信息(PSCCH)，数据信息(PSSCH)以及反馈信息(PSFCH)中的任何一种。例如，所述第一信息/所述第二信息包括如下信息中的至少一种信息：物理下行共享信道(physical DL shared channel，PDSCH)、物理上行共享信道(physical UL shared channel，PUSCH)、物理下行控制信道(physical DL control channel，PDCCH)、物理上行控制信道(physical UL control channel，PUCCH)、响应参考信号(sounding reference signal，SRS)、信道状态信息参考信号(channel state information-reference signal SL-CSI-RS)、反馈信道(physical hybird ARQ indicator channel，PHICH)、同步信息。类似的地方不再一一描述，即第一信息/第二信息可以是去掉SL这种特定限制的对应信息，例如，对PSCCH去掉SL这种特定限制的可以对应的为PUCCH/PDCCH。
下面以V2X场景为例，且以第一链路是侧行链路，第二链路是蜂窝链路为例。

当终端满足调度限制不适用或者没有调度限制的条件时，停止基于蜂窝链路的第二信息的测量。当终端满足调度限制适用或者有调度限制的条件时，进行基于蜂窝链路的第二信息的测量。
或者，当终端满足调度限制不适用或者没有调度限制的条件时，进行第二信息的测量。当终端满足调度限制适用或者有调度限制的条件时，停止第二信息的测量。
本申请中“停止”可以替换为“取消”。
所述判断是否满足调度限制条件包含判断调度是否适用，或者说，判断是否存在调度限制，或者说判断是否适用调度限制。通常情况下，系统使用一种方式即可，若调度适用(存在调度限制或适用调度限制，本申请实施例对此名称不限定)时，优先使用调度，调度不适用(不存在调度限制或不适用调度限制，本申请实施例对此名称不限定)时，优先使用RRM测量的方式。当然，也可以换一种描述，即若调度适用(存在调度限制或适用调 度限制，本申请实施例对此名称不限定)时，优先使用RRM测量的方式，调度不适用(不存在调度限制或不适用调度限制，本申请实施例对此名称不限定)时，优先使用调度。
继续以RRM测量为例，终端满足调度不适用或者没有调度限制的条件时，可以停止基于第二信息(比如CSI-RS)的RRM测量，进行第一信息的收发；当终端满足调度限制适用，或者有调度限制的条件时，终端停止第一信息的收发，基于第二信息(比如CSI-RS)进行RRM测量。或者，终端满足调度限制适用，或者有调度限制时，可以停止基于第二信息(比如CSI-RS)的RRM测量，进行第一信息的收发；当终端满足调度不适应或者没有调度限制的条件时，终端停止第一信息的收发，基于第二信息(比如CSI-RS)进行RRM测量。这样，可以促成当RRM测量不受调度的限制时，确保RRM的测量；相反，当RRM测量受调度的限制时，给以调度优先权。其中，所述调度限制为受RRM影响的调度限制，即所述调度限制为调度的收发受到RRM测量的影响或者被RRM测量所制约。
其中，测量可以是无线资源管理(radio resource management，RRM)测量，或者对于同步信号的测量，或者对于广播信道块的测量，本申请实施例不作限定。其中，RRM测量包括基于CSI-RS或者DMRS的测量；对于同步信号的测量包括基于SS或SSB的测量，对于广播信道块的测量包括基于PBCH block的测量。
需要说明的是，在5G NR系统中，支持带宽传输，为了保障在有限的带宽条件下终端的业务质量，系统支持为终端灵活的分配和动态的调整资源，以最大程度的提升资源的利用率。系统支持调度和基于测量(比如RRM测量)的两种资源分配方式，其中，基于RRM测量的方式，侧重于小区重选，切换等场景(比如，终端可以接收非服务小区的其它小区的RRM测量报告，基于该RRM测量报告决定是否进行小区切换等)。通常情况下，系统使用一种方式即可，若调度适用(存在调度限制或适用调度限制，本申请实施例对此名称不限定)时，优先使用调度，调度不适用(不存在调度限制或不适用调度限制，本申请实施例对此名称不限定)时，优先使用RRM测量的方式。当然，也可以换一种描述，即若调度适用(存在调度限制或适用调度限制，本申请实施例对此名称不限定)时，优先使用RRM测量的方式，调度不适用(不存在调度限制或不适用调度限制，本申请实施例对此名称不限定)时，优先使用调度。
继续以RRM测量为例，终端满足调度不适用或者没有调度限制的条件时，可以停止基于第二信息(比如CSI-RS)的RRM测量，进行第一信息的收发；当终端满足调度限制适用，或者有调度限制的条件时，终端停止第一信息的收发，基于第二信息(比如CSI-RS)进行RRM测量。或者，终端满足调度限制适用，或者有调度限制时，可以停止基于第二信息(比如CSI-RS)的RRM测量，进行第一信息的收发；当终端满足调度不适应或者没有调度限制的条件时，终端停止第一信息的收发，基于第二信息(比如CSI-RS)进行RRM测量。这样，可以促成当RRM测量不受调度的限制时，确保RRM的测量；相反，当RRM测量受调度的限制时，给以调度优先权。其中，所述调度限制为受RRM影响的调度限制，即所述调度限制为调度的收发受到RRM测量的影响或者被RRM测量所制约。
再例如，对于频带FR1的一个小区上的不成对的频谱操作，当调度限制不适用时，如果UE检测到DCI(DCI0_0,DCI0_1,DCI1_0,DCI1_1,或DCI2_3)指示UE在一系列符号上传输数据；或者UE检测到一个Uu接口的DCI(调度SL)或者SFI-SL指示UE在该系列符号中至少一个符号上传输/接收SL数据(比如，PSSCH/PSCCH/SL-SRS/SL-CSI-RS)，UE不被要求进行RRM测量(比如，不被要求基于SS/PBCH block或者CSI-RS接收在该FR1频段内 另一个小区上的RRM测量报告)。
又例如，以对于同步信号的测量为例，终端满足调度不适应或者没有调度限制的条件时，可以停止基于第二信息(比如SS block)的测量，进行第一信息的收发；当终端满足调度限制适用，或者有调度限制时，终端停止第一信息的收发，基于第二信息(比如CSI-RS)进行测量。或者，终端满足调度限制适用，或者有调度限制时，可以停止基于第二信息(比如SS block)的测量，进行第一信息的收发；当终端满足调度不适用或者没有调度限制的条件时，终端停止第一信息的收发，基于第二信息(比如CSI-RS)进行测量。
可选的，RRM测量也可以包括基于SS或SS block的测量，基于广播信道块(PBCH block)的测量，不多赘述。
