本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备也可以称为接入网设备或无线接入网设备，如网络设备可以是基站。本申请实施例中的网络设备可以是指将终端设备接入到无线网络的无线接入网(radio access network，RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称，或与如下名称进行替换，比如：节点B(NodeB)、演进型基站(evolved NodeB，eNB)、下一代基站(next generation NodeB，gNB)、中继站、接入点、传输点(transmitting and receiving point，TRP)、发射点(transmitting point，TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont，AP)、传输节点、收发节点、基带单元(base band unit，BBU)、射频拉远单元(Remote Radio Unit，RRU)、有源天线单元(active antenna unit，AAU)、射频头(remote radio head，RRH)、中心单元(central unit，CU)、分布式单元(distributed unit，DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物，或其组合。基站还可以指用于设置于前述设备或装置内的通信模块、调制解调器或芯片。基站还可以是移动交换中心以及设备到设备D2D、车辆外联(vehicle-to-everything，V2X)、机器到机器(machine-to-machine，M2M)通信中承担基站功能的设备、6G网络中的网络侧设备、未来的通信系统中承担基站功能的设备等。基站可以支持相同或不同接入技术的网络。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。

不同网络覆盖情况下的侧行通信
侧行通信指的是基于侧行链路的通信技术。侧行通信例如可以是D2D或V2X。侧行通信支持在终端设备与终端设备之间直接进行通信数据传输。相比于传统的蜂窝通信，侧行通信中网络设备可以不再是控制中心，并且终端设备与终端设备可以在没有网络的情况下进行直接通信，终端设备之间直接进行通信数据的传输可以具有更高的频谱效率以及更低的传输时延。例如，车联网系统采用侧行通信技术，车辆可以和附近的车辆进行通信，进行防撞预警等应用。
在侧行通信中，根据终端设备所处的网络覆盖的情况，可以将侧行通信分为网络覆盖内(in coverage scenario)的侧行通信，部分网络覆盖(partial coverage scenario)的侧行通信，及网络覆盖外(out of coverage scenario)的侧行通信。
图2为网络覆盖内的侧行通信的场景示例图。在图2所示的场景中，两个终端设备120a均处于网络设备110的网络覆盖范围内。因此，两个终端设备120a均可以接收网络设备110的配置信令(本申请中的配置信令也可替换为配置信息)，并根据网络设备110的配置信令确定侧行配置。在两个终端设备120a均进行侧行配置之后，即可在侧行链路上进行侧行通信。
图3为部分网络覆盖的侧行通信的场景示例图。在图3所示的场景中，终端设备120a与终端设备120b进行侧行通信。终端设备120a位于网络设备110的覆盖范围内，因此终端设备120a能够接收到网络设备的配置信令，并根据网络设备110的配置信令确定侧行配置。终端设备120b位于网络设备110的网络覆盖范围外，无法接收网络设备110的配置信令。在这种情况下，终端设备120b可以根据预配置(pre-configuration)信息和/或位于网络覆盖范围内的终端设备120a发送的物理侧行广播信道(physical sidelink broadcast channel，PSBCH)中携带的信息确定侧行配置。在终端设备120a和终端设备120b均进行侧行配置之后，即可在侧行链路上进行侧行通信。
图4为网络覆盖外的侧行通信的场景示例图。在图4所示的场景中，两个终端设备120b均位于网络覆盖范围外。在这种情况下，两个终端设备120b均可以根据预配置信息确定侧行配置。在两个终端设备120b均进行侧行配置之后，即可在侧行链路上进行侧行通信。
侧行通信的通信方式
某些侧行通信系统(如LTE-V2X)支持基于广播的通信方式，也可以称为支持基于广播的数据传输方式(下文简称广播方式)。对于广播方式，接收端终端设备可以为发送端终端设备周围的任意一个终端设备。换句话说，广播方式为一个终端设备面向未知的多个终端设备的通信方式。以图5为例，终端设备1是发送端终端设备，该发送端终端设备对应的接收端终端设备是终端设备1周围的任意一个终端设备，例如可以是图5中的终端2-终端6。
除了广播方式之外，某些通信系统还支持基于单播的通信方式(下文简称单播方式)和/或基于组播的通信方式(下文简称组播方式)。例如，NR-V2X希望支持自动驾驶。自动驾驶对车辆之间的数据交互提出了更高的要求。例如，车辆之间的数据交互需要更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配方式等。因此，为了提升车辆之间的数据交互性能，NR-V2X引入了单播方式和组播方式。
对于单播方式，接收端终端设备一般只有一个终端设备，即单播方式为两个终端设备间直接一对一进行通信。以图6为例，终端设备1和终端设备2之间进行的是单播传输。终端设备1可以为发送端终端设备，终端设备2可以为接收端终端设备，或者终端设备1可以为接收端终端设备，终端设备2可以为发送端终端设备。
对于组播方式，接收端终端设备可以是一个通信组(group)内的终端设备，或者，接收端终端设备可以是在一定传输距离内的终端设备。换句话说，组播方式为一个终端设备面向多个已知终端设备的通信方式。以图7为例，终端设备1、终端设备2、终端设备3和终端设备4构成一个通信组。如果终端设备1发送数据，则该组内的其他终端设备(终端设备2至终端设备4)均可以是接收端终端设备。
侧行通信的模式
某些标准或协议(如第三代合作伙伴计划(3rd Generation Partnership Project，3GPP))定义了两种侧行通信的模式(或称传输模式)：第一模式和第二模式。
在第一模式下，终端设备的资源(本申请提及的资源也可称为传输资源，如时频资源)是由网络设备分配的。终端设备可以根据网络设备分配的资源在侧行链路上进行数据的发送。网络设备可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。该第一模式可以应用于有网络设备覆盖的场景，如前文图2所示的场景。在图2所示的场景中，终端设备120a位于网络设备110的网络覆盖范围内，因此网络设备110可以为终端设备120a分配侧行传输过程中使用的资源。
在第二模式下，终端设备可以自主在资源池(resource pool，RP)中选取一个或多个资源，这种方式也可以称为预定义的资源池方式。然后，终端设备可以根据选择出的资源进行侧行传输。例如，在图4所示的场景中，终端设备120b位于小区覆盖范围外。因此，终端设备120b可以在预配置(预定义)的资源池中自主选取资源进行侧行传输。或者，在图2所示的场景中，终端设备120a也可以在网络设备110配置的资源池中自主选取一个或多个资源进行侧行传输。
资源池
资源池指的是资源的集合。侧行链路的资源池指的是用于侧行传输的资源(时频资源)的集合。侧行链路中的数据的发送和接收一般是在资源池中进行的。资源池可以包括发送资源池和接收资源池。发送资源池可用于发送侧行数据，接收资源池可用于接收侧行数据。终端设备可以通过预配置信息和/或网络设备的配置信令从资源池中选取对应的资源进行侧行通信。为了保证终端设备能够接收其他终端设备发送的侧行数据，对于需要进行侧行通信的两个终端设备，一个终端设备被配置的接收资源池的时频资源通常应该包括另一终端设备被配置的发送资源池的时频资源。
前文提到，侧行通信的模式可以包括第一模式和第二模式。在第一模式下，终端设备可以基于网络设备的指示选取资源池。在第二模式下，终端设备可以自主选择资源池，例如，终端设备可以从资源池中自主选择发送数据的资源。在有些实施例中，资源池还可以包括异常资源池(exceptional resource pool)。例如，当终端设备没有获取到足够的侦听结果时，可以临时地使用该异常资源池中的资源发送数据。
终端设备的功率等级
根据终端设备能够支持的最大发射功率，可以将终端设备划分为不同功率等级(power class，PC)的终端设备，如PC3终端设备、PC2终端设备等。根据现有协议的规定，PC3终端设备的最大发送功率一般为23分贝毫瓦(dBm)，PC2终端设备的最大发送功率一般为26dBm。
不同功率等级的终端设备的发射信号覆盖范围不同。一般而言，功率等级较高的终端设备(下文简称为高功率终端设备)的发射信号覆盖范围大于功率等级较低的终端设备(下文简称为低功率终端设备)的发射信号覆盖范围。因此，在某些场景下，当低功率终端设备处于高功率终端设备的发射信号覆盖范围之内时，高功率终端设备可能会处于低功率终 端设备的覆盖范围之外。
以图8为例，该侧行通信场景中包括低功率终端设备(PC3终端设备)和高功率终端设备(PC2终端设备)，PC3终端设备处于PC2终端设备的发射信号覆盖范围之内，而PC2终端设备处于PC3终端设备的覆盖范围之外，也就意味着PC3终端设备发射的信号无法被PC2终端设备接收，而PC2终端设备发射的信号则可以被PC3终端设备接收。
如前文所述，在某些侧行通信的场景中，终端设备采用预定义的资源池方式时，终端设备可以自主选取资源池中的资源进行数据的发送和接收。但为了避免存在其他终端设备也在使用该资源，相关技术中，要求终端设备在选取资源时需要先侦听是否有其他终端设备的发射信号。如果终端设备侦听到有其他终端设备的发射信号，则终端设备需要更换资源，或者，需要回退一定的时间后继续进行侦听，直到选取到空闲的资源以进行数据的发送和接收。这种终端设备在发射信号之前进行侦听的规则，可以确保资源的公平使用，先到先得。
但是，目前的资源池是针对所有终端设备定义的统一的资源池，终端设备不论是什么功率等级都在同一个资源池中进行资源的选取，导致不同功率等级的终端设备可能会选取资源池中的同一侧行资源进行侧行通信，从而造成相互干扰。
例如，继续以图8为例，当PC3终端设备首先在资源池中选取了空闲资源进行通信，而之后PC2终端设备进行信号的侦听，由于PC2终端设备处于PC3终端设备的发射信号覆盖范围外，侦听不到PC3终端设备的信号，因此PC2终端设备也可能选取并使用与PC3终端设备相同的资源。此时，即使在PC3终端设备已经完成对资源池内对应资源抢占的情况下，PC2终端设备的信号也会对PC3终端设备产生干扰。
针对上述问题，本申请提出两个实施例。其中，实施例1旨在引入与终端设备的功率等级对应的资源池，使得第一终端设备能够在自己的功率等级对应的资源池中进行侧行通信，从而可以降低其他功率等级的终端设备对第一终端设备的干扰。实施例2旨在通过测量到终端设备被干扰后，变更终端设备侧行通信的资源以实现对干扰信号的规避。下文分别对实施例1和实施例2进行描述。
实施例1
本申请实施例中，可以建立终端设备的功率等级与资源池的对应关系。换句话说，终端设备可以使用该终端设备对应的资源池进行侧行通信。
在一些实施例中，可以仅为一个功率等级的终端设备建立对应的资源池。例如，可以为功率等级为PC2的终端设备设置对应的资源池，其他功率等级的终端设备可以从公共资源池中选取资源。
在一些实施例中，可以为多个功率等级的终端设备建立各自对应的资源池。例如，终端设备可以包括M个功率等级(M为大于或等于2的正整数)，该M个功率等级与M个资源池一一对应。示例性地，如图9所示，终端设备的功率等级包括PC2和PC3，可以建立PC2对应的PC2资源池和PC3对应的PC3资源池。功率等级为PC2的终端设备可以在PC2资源池进行通信；功率等级为PC3的终端设备可以在PC3资源池进行通信。由于不同功率等级的终端设备对应的资源池不同，因此，在侧行通信时，不同功率等级的终端设备可以在不同的资源池中选择资源，从而可以避免受到其他等级的终端设备的干扰或对其他功率等级的终端设备产生干扰。
在一些实施例中，本申请实施例提及的资源池，还可以包括不同功率等级的终端设备共享的公共资源池。例如，当某个功率等级的终端设备对应的资源池中没有空闲资源时，终端设备可以利用该公共资源池中的资源进行侧行通信。
建立终端设备的功率等级与资源池的对应关系的方式可以有多种，本申请对此并不限定。作为一个示例，可以通过协议预定义的方式。具体地，作为一种实现方式，可以采用预定义的方式将功率等级与资源池的对应关系存储于终端设备中。基于此，终端设备可以根据自身的功率等级在对应的资源池里面选取空闲资源进行数据的发送或接收。协议预定 义的方式可以适用于侧行通信的各种应用场景，例如前文所述的网络覆盖内、部分网络覆盖、以及网络覆盖外的应用场景。
作为另一个示例，可以通过网络设备配置的方式。具体地，作为一种实现方式，网络设备可以配置不同功率等级与资源池的对应关系，并通过高层信令(如无线资源控制(radio resource control，RRC)信令)的方式告知给终端设备。终端设备收到该高层信令后，可以自主在其功率等级对应的资源池中完成资源的选取。网络设备配置的方式可以适用于网络覆盖内以及部分网络覆盖的应用场景。在一些实施例中，网络设备配置好不同功率等级与资源池的对应关系之后，网络设备可以根据终端设备的功率等级，在对应的资源池内进行资源的调度，以保证终端设备在对应的资源池中进行侧行通信。
在建立终端设备的功率等级与资源池的对应关系之后，终端设备可以基于该对应关系，利用对应的资源池中的资源进行侧行通信。
图10为实施例1提供的无线通信的方法的示意性流程图。图10是站在第一终端设备和网络设备的角度进行描述的。第一终端设备例如可以是图1至图4中的终端设备120，网络设备例如可以是图1中的网络设备110。
参见图10，在步骤S1020，第一终端设备利用第一资源池中的资源进行侧行通信。第一资源池与第一终端设备的功率等级对应。例如，该第一终端设备的功率等级为PC2，则第一资源池可以是PC2对应的资源池；又如，该第一终端设备的功率等级为PC3，则第一资源池可以是PC3对应的资源池。
本申请实施例中，引入了与终端设备的功率等级对应的资源池，使得第一终端设备能够在自己的功率等级对应的资源池中进行侧行通信，从而可以降低其他功率等级的终端设备对第一终端设备的干扰。
在一些实施例中，如果终端设备的功率等级与资源池的对应关系是网络设备配置的，在步骤S1020之前，还可以包括步骤S1010。
在步骤S1010，网络设备向第一终端设备发送第一信息。第一信息用于指示第一资源池与第一终端设备的功率等级对应；或者，第一信息用于调度第一终端设备在与第一终端设备的功率等级对应的第一资源池进行侧行通信。
在一些实施例中，第一信息可以是高层信令，例如RRC信令。
第一终端设备接收到网络设备发送的第一信息后，可以根据第一信息，利用第一资源池中的资源进行侧行通信。
第一资源池的选取方式可以有多种，本申请实施例对此并不限定。示例性地，本申请实施例给出三种可能的实现方式。
方式一：第一终端设备基于第一终端设备的功率等级选取
按照终端设备的功率等级对资源池进行分配之后，第一终端设备可以基于自身的功率等级，直接从多个资源池中，选取与自身功率等级对应的第一资源池。
方式二：第二终端设备基于第二终端设备的功率等级选取
第二终端设备为与第一终端设备进行侧行通信的终端设备。按照终端设备的功率等级对资源池进行分配之后，可以通过第二终端设备，间接地选取与第一终端设备的功率等级对应的第一资源池。
作为一种实现方式，第二终端设备可以基于自身的功率等级选取与第二终端设备功率等级对应的资源池作为第一资源池。第二终端设备作为与第一终端设备进行侧行通信的终端设备，和第一终端设备可以从同一资源池中选取资源，因此，第二终端设备的功率等级对应的资源池可以作为第一终端设备选取资源池的参考。
方式三：网络设备基于第一终端设备和/或第二终端设备的功率等级选取
在一些实施例中，第一终端设备和/或第二终端设备可以将自身的功率等级上报给网络设备，网络设备可以基于第一终端设备和/或第二终端设备上报的功率等级信息，为第一终端设备选取对应的第一资源池。在该实施例中，网络设备基于第一终端设备和/或第二终 端设备的功率等级选取第一资源池，也可以解释为网络设备基于第一终端设备和/或第二终端设备的功率等级进行资源调度，从而为第一终端设备分配对应的资源。
实施例2
在一些实施例中，第一终端设备可以根据干扰测量的结果变更资源，从而实现对干扰信号的规避。
干扰测量的实现方式可以有多种，本申请实施例对此并不限定。例如，当第三终端设备对第一终端设备和第二终端设备之间的侧行通信造成干扰时，可以基于第一终端设备和/或第二终端设备实现干扰测量。
在一些实施例中，第三终端设备的功率等级与第一终端设备的功率等级不同，例如，第三终端设备的功率等级大于第一终端设备的功率等级。
在一些实施例中，第一终端设备和第二终端设备之间存在反馈链路，即第一终端设备和第二终端设备之间的侧行通信是双向的。在一些实施例中，第一终端设备和第二终端设备的双向通信方式与第一终端设备的侧行通信模式无关，也就是说，不论第一终端设备处于单播、组播或广播模式下，第一终端设备和第二终端设备之间的侧行通信均可以是双向的。
作为一个示例，参见图11所示的一种可能的应用场景，其中，第一终端设备和第二终端设备之间是双向通信的，第三终端设备的信号可以对第一终端设备和第二终端设备的侧行通信产生干扰。
接下来，本申请实施例示例性地给出三种干扰测量可能的实现方式。
方式一：基于第二终端设备的干扰反馈
在该方式下，干扰的测量是通过被干扰的目标终端(第二终端设备)进行的。作为一种实现方式，第二终端设备被干扰后，可以向与其进行侧行通信的第一终端设备发送干扰指示信息。当第三终端设备的发射信号对正在与第一终端设备通信的第二终端设备造成干扰时，第二终端设备将同时接收到来自第一终端设备的信号以及来自第三终端设备的干扰信号。如前文所述，第一终端设备和第二终端设备的侧行通信为双向的，此时，第二终端设备可以根据接收到的第三终端设备的干扰信号，向第一终端设备发送干扰指示信息。
在一些实施例中，干扰指示信息可以用于指示第一终端设备和第二终端设备之间的侧行通信被干扰，该干扰指示信息例如可以采用1比特指示该侧行通信被干扰。在一些实施例中，干扰指示信息还可以用于指示该侧行通信的干扰强度。作为一个示例，干扰强度可以采用强度数值表示；作为另一个示例，干扰强度也可以采用干扰等级表示。
在一些实施例中，第二终端设备在向第一终端设备发送干扰指示信息之前，可以先进行干扰测量。如果干扰测量结果显示干扰达到某一预设门限，第二终端设备向第一终端设备发送干扰指示信息。例如，终端设备之间处于运动状态时，其干扰的大小是变化的，当第二终端设备检测到干扰达到该预设门限时，该干扰对第一终端设备和第二终端设备之间的通信影响较大，此时第二终端设备可以向第一终端设备发送干扰指示信息。
在一些实施例中，预设门限可以包括干扰强度门限。当干扰测量结果显示干扰超过某一预设干扰强度时，第二终端设备可以向第一终端设备发送干扰指示信息。在一些实施例中，预设门限还可以包括信号与干扰加噪声比(signal to interference plus noise ratio，SINR)门限，简称为信噪比门限。当干扰测量结果显示第二终端设备检测到的接收信号的信噪比门限低于某一预设信噪比时，第二终端设备可以向第一终端设备发送干扰指示信息。
方式二：基于第一终端设备的干扰测量
在该方式下，干扰的测量是通过被干扰的第一终端设备完成的，即第一终端设备可以直接进行干扰测量。由于第一终端设备与第二终端设备之间是双向通信方式，因此，在第一终端设备的接收时间内，第一终端设备可以同时检测干扰信号的强度。
在一些实施例中，当第一终端设备检测到干扰信号后，可以主动变更资源，在资源池内的新空闲资源上重新建立与第二终端设备的通信连接。
在一些实施例中，当第一终端设备检测到干扰信号达到某一预设门限后，可以主动变更资源，在资源池内的新空闲资源上重新建立与第二终端设备的通信连接。该预设门限可以为干扰强度门限和/或信噪比门限，例如超过干扰强度门限或低于信噪比门限。
方式三：结合第二终端设备的干扰反馈和第一终端设备的干扰测量
如图11所示的终端设备之间的位置关系可以是动态变化的，而且可能会间隔比较远。这种情况下，第三终端设备的发射信号带来的干扰可能只影响第一终端设备、或可能只影响第二终端设备、或同时影响第一终端设备和第二终端设备。因此，在一些实施例中，可以结合第二终端设备的干扰反馈和第一终端设备的干扰测量，以便提高干扰检测的准确性。作为一种实现方式，当第一终端设备和第二终端设备中有任一测量结果显示第一终端设备被干扰，第一终端设备可以基于该测量结果主动变更资源，在资源池内的新空闲资源上重新建立与第二终端设备的通信连接。
在一些实施例中，第一终端设备和第二终端设备中有任一测量结果显示第一终端设备被干扰，可以是指，测量结果显示干扰达到某一预设门限。该预设门限可以为干扰强度门限和/或信噪比门限，例如超过干扰强度门限或低于信噪比门限。
预设门限的配置可以有多种方式，本申请实施例对此并不限定。例如，预设门限是由协议预定义的，即预设门限的取值可以为预设值。在一些实施例中，预设门限例如可以为定值，即针对任意功率等级的终端设备，预设门限的取值均可以采用相同取值。在一些实施例中，预设门限的取值也可以是变化的。或者，预设门限是由网络设备配置的。例如，网络设备可以通过高层信令(如RRC信令)进行配置。
基于上文所述的干扰测量，第一终端设备可以根据干扰测量的结果变更资源。
图12为实施例2提供的无线通信的方法的示意性流程图。图12中的方法可以由第一终端设备和第二终端设备执行，第一终端设备和第二终端设备之间可以进行侧行通信。其中，第一终端设备和第二终端设备例如可以是图1至图4中的终端设备120。
参见图12，在步骤S1220，第一终端设备根据第一条件，变更侧行通信的资源。第一条件用于指示第一终端设备的侧行通信被干扰。
本申请实施例中，第一终端设备知晓自身的侧行通信被干扰后，通过变更自身侧行通信的资源以实现对干扰信号的规避。
在一些实施例中，第一条件包括第一终端设备接收到第二终端设备发送的干扰指示信息。
具体地，在步骤S1220之前，还可以包括步骤S1210。在步骤S1210，第二终端设备向第一终端设备发送干扰指示信息。第一终端设备接收到干扰指示信息后，根据该干扰指示信息，变更侧行通信的资源。关于干扰指示信息的描述，可以参见前文，此处不再赘述。
在一些实施例中，干扰指示信息用于指示第一终端设备和第二终端设备之间的侧行通信被干扰。或者，干扰指示信息用于指示第一终端设备和第二终端设备之间的侧行通信的干扰强度。
在一些实施例中，第一条件包括侧行通信的干扰达到预定门限。示例性地，该预设门限可以包括干扰强度门限和/或信噪比门限。关于预定门限的描述，可以参见前文，此处不再赘述。
在一些实施例中，侧行通信的干扰是否达到预定门限是由第一终端设备和/或第二终端设备测量确定。
在一些实施例中，第一终端设备和第二终端设备之间的侧行通信的干扰来自第三终端设备，且该第三终端设备的功率等级大于第一终端设备的功率等级。
