不同网络覆盖下的侧行通信
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。传统的蜂窝系统中的通信数据在终端设备和网络设备之间进行接收或者发送，而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，终端设备与终端设备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。
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 内的侧行通信，部分网络覆盖的侧行通信，及网络覆盖外的侧行通信。
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110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。
通信系统中的资源分配方式
某些标准或协议(如第三代合作伙伴计划(3rd Generation Partnership Project，3GPP))定义了多种资源分配方式，例如，上下行通信对应的多种资源分配方式、侧行通信对应的多种资源分配方式等。
上下行通信(终端设备与网络设备之间的通信)的场景下，终端设备在Uu接口发送上行信号的时候，基本都是利用网络设备调度资源的方式来确定(或选择)发送该上行信号的资源(本申请提及的资源也可称为无线资源或者传输资源，如时频资源)，即发送该上行信号的资源是由网络设备调度的，也可以理解为是由网络设备分配的。而终端设备能够自主选择资源的应用场景有限，只有在随机接入时，终端设备可以利用自主选择资源的方式来确定随机接入资源。例如，采用四步随机接入的方式时，终端设备可以自主选择承载随机接入前导码(preamble)的资源；或者，采用两步随机接入的方式时，终端设备可以自主选择承载preamble和物理上行共享信道(physical uplink shared channel，PUSCH)单元的资源。
在一些实现方式中，网络设备调度资源的方式可以包括网络设备为终端设备动态调度资源的方式(简称为动态调度的方式)。在上行方向上，完全的动态调度一般是由终端设备触发的。比如，在目前的5G系统中，终端设备可以发送调度请求给网络设备，然后网络设备会应答调度授权给终端设备，以便终端设备能够基于调度授权发送上行信号。网络设备向终端设备动态调度资源的好处是，一旦网络设备向终端设备发送了调度授权，该调度授权关联的资源是专门给所调度的终端设备单独使用的，不存在终端设备之间发生资源冲突的问题，不过这种方式也存在缺点，例如，在用户面引入了过长的时延。
在一些实现方式中，网络设备调度资源的方式可以包括网络设备为终端设备预配置资源的方式(简称为基于预配置的资源分配方式)。在上行方向上，网络设备可以为终端设备预配置一些资源，该终端设备可以使用预配置的资源发送上行信号。与动态调度的方式相比，基于预配置的资源分配方式能够缩短用户面的时延，不过上行并不是总有数据需要发送，因此，预配置的资源中不使用的资源其实就浪费了。
某些标准或协议(例如3GPP)定义了两种侧行通信的资源分配方式(或称侧行通信的模式、侧行通信的传输模式等)：第一模式和第二模式。
在第一模式下，终端设备的资源是由网络设备调度的。终端设备可以根据网络设备调度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调度单次传输的资源，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。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可以在资源池中自主选取资源进行侧行传输。
侧行通信的场景下，终端设备在PC5接口发送侧行信号的时候，可以采用第一模式或者第二模式来确定发送该侧行信号的资源。
然而，无论在上下行通行的场景还是在侧行通信的场景下，虽然存在有多种资源分配方式，但是采用哪种资源分配方式来确定承载无线信号(比如上行信号、侧行信号)的资源均是由协议规定的，或者是由网络设备确定的，终端设备本身没有自主决策(决定)的权利。换句话说，针对某待发送的无线信号，承载该无线信号的资源应该由网络设备调度还是由终端设备自主选择，实质是协议规定好的或者是由网络设备确定的，终端设备自己不能决策。
以上下行通信的场景为例，协议规定随机接入资源可以由终端设备自主选择，而终端设备发送其他信号的资源则是由网络设备调度。终端设备不能决定某一信号对应的资源是由网络设备调度还是终端设备自主选择。
以侧行通信的场景为例，终端设备采用第一模式还是第二模式进行侧行资源的选取是由协议或者网络规定的，比如，如果终端设备在网络的覆盖范围之外，那么终端设备只能采用第二模式进行侧行资源的选取。终端设备不能决定某一信号对应的资源是由网络设备调度还是终端设备自主选择。
上述的技术有一个比较大的背景是蜂窝网络的覆盖范围较大，往往在百米以上，而一个蜂窝中的用户通常情况下至少有几十个以上。而随着无线通信技术的发展，用户对高传输速率和大带宽的要求越来越高。为了满足用户的要求，无线通信系统的频谱越来越高，带宽会越来越大，而网络的覆盖范围则随之减小，使得网络覆盖范围内共享大带宽的用户也越来越少。比如，在以后的太赫兹蜂窝中，可能一个蜂窝中只有几个用户，网络覆盖范围内的大带宽仅由这几个用户共享。这种情况下，如何提高无线通信系统的性能成为需要解决的问题。
为了解决上述问题，本申请实施例提供一种用于确定资源分配方式的方案，以提高无线通信系统的性能。
图5为本申请实施例提供的用于确定资源分配方式的方法的流程示意图。图5所示的方法是站在终端设备和网络设备交互的角度进行描述的，该终端设备和网络设备例如可以是图1至图4中所示的终端设备120和网络设备110。图5所示的方法可以包括步骤S510，下面对该步骤进行详细介绍。
在步骤S510，终端设备从多种资源分配方式中确定第一资源分配方式。
资源可以用于承载终端设备与网络设备之间的上下行信号，或者可以用于承载终端设备与终端设备之间的侧行信号。
资源可以在各个维度上进行多址接入，比如，在时域、频域和码域等维度上进行多址接入。对应地，资源可以是指时域资源、频域资源、码域资源等，本申请实施例对资源的类型不作具体限定。
对终端设备而言，终端设备向网络设备发送上行信号或者向终端设备发送侧行信号时，承载该上行信号或侧行信号的资源是通过一定的资源分配方式得到的。
能够为终端设备分配资源的资源分配方式有多种，本申请实施例对此并不限定。例如，该多种资源分配方式可以包括网络设备调度资源的方式和终端设备自主选择资源的方式。
网络设备调度资源的方式可以是指，发送无线信号(比如，上行信号或侧行信号)的资源是由网络设备调度的。终端设备可以基于网络设备调度的资源在上行链路上发送上行信号或者在侧行链路上发送侧行信号。
终端设备自主选择资源的方式可以是指，发送无线信号的资源是终端设备在资源池中自主选择的。或者说，采用终端设备自主选择资源的方式确定的资源是终端设备从资源池中选择的资源。终端设备可以基于自主选择的资源在上行链路上发送上行信号或者在侧行链路上发送侧行信号。
在一些实施例中，终端设备自主选择资源可以是指，终端设备自主为自己选择资源。在一些实施例中，终端设备自主选择资源可以是指，终端设备自主为其他终端设备(比如与其进行侧行通信的终端设备)选择资源。
第一资源分配方式是终端设备从上文提及的多种资源分配方式中确定出的。终端设备确定第一资源分配方式后，可以按照第一资源分配方式来确定发送无线信号的资源。换句话说，终端设备可以确定(或选择)使用哪种资源分配方式来选取承载无线信号的资源。
例如，终端设备可以确定第一资源分配方式为网络设备调度资源的方式，即终端设备可以确定使用网络设备调度资源的方式来选取资源。或者，终端设备可以确定第一资源分配方式为终端设备自主选择资源的方式，即终端设备可以确定使用终端设备自主选择资源的方式来选取资源，以利用选取的资源发送无线信号。
本申请实施例中，终端设备能够从多种资源分配方式中确定第一资源分配方式。也就是说，终端设备具有自主确定资源分配方式的能力，使得终端设备能够根据不同情况采用不同的资源分配方式来选择资源，提高资源选择的灵活性，从而提高无线通信系统的性能。
在一些实施例中，终端设备确定第一资源分配方式为网络设备调度资源的方式的情况下，终端设备可以通过预配置的无线信道(比如，上行控制信道)，请求网络设备进行资源调度。当终端设备接收到网络设备发送的调度授权后，可以在调度授权中包含的资源上进行无线信号的发送。在一些实施例中，调度授权中还可以规定在该资源上发送无线信号的方式，这种情况下，终端设备可以在该资源上按照调度授权所规定的方式进行无线信号的发送，例如，发送上行信号或侧行信号。
在一些实施例中，采用网络设备调度资源的方式确定承载无线信号的资源的情况下，终端设备可以向网络设备发送终端设备的当前缓存的信息，以触发后续的调度授权。例如，终端设备使用调度授权的资源发送上行信号时，可以在该上行信号中包含当前缓存的信息；或者，终端设备使用调度授权的资源发送侧行信号时，终端设备可以向网络设备单独发送当前缓存的信息，或承载于其他信号中发送。
网络设备调度资源的方式可以包括多种，本申请实施例对此并不限定。示例性地，网络设备调度资源的方式可以包括动态调度的方式和/或半静态调度的方式。动态调度的方式下，网络设备对终端设备的每个数据包都有一个相应的下行控制信令来通知其占用的资源和传输方式。半静态调度的方式下，网络设备在启动半静态传输时发送一次下行控制信令，终端设备根据这个下行控制信令所指示的资源启动半静态传输，终端设备按照一定周期进行数据包的传输和接收，直到有另一个特殊格式的下行控制信令来终止半静态传输。
不过本申请实施例并不限定于此，在一些实施例中，网络设备调度资源的方式还可以包括基于预配置的资源分配方式等，只要承载终端设备需要发送的无线信号的资源是由网络设备调度的即可。
在一些实施例中，终端设备确定第一资源分配方式为终端设备自主选择资源的方式的情况下，终端设备可以在资源池中随机选择发送无线信号所需要的资源。示例性地，如果终端设备具备侦听能力，终端设备在资源池中选择资源时，可以通过侦听的方式获取资源 池中可用的资源集合，然后从该集合中随机选择一个资源进行无线信号的发送；如果终端设备不具备侦听能力，终端设备可以直接在资源池中随机选择一个资源进行无线信号的发送。
本申请实施例对资源池的来源不作具体限定。在一些实施例中，资源池可以是预配置给终端设备的。在一些实施例中，资源池可以是网络设备配置和广播的，这种情况下，可以理解为终端设备可以在网络设备指定的资源池中选择所需要的资源。作为一种具体的实现方式，网络设备可以通过公共或专用的信令通知终端设备，在哪些资源上允许终端设备自主选择资源进行无线信号的发送。
在一些实施例中，网络设备通过公共或专用的信令通知终端设备资源池的相关信息时，还可以在信令中规定发送数据的某些参数，这些参数可以是一套或者多套参数，以及他们的组合，比如功率控制参数，调制和信道编号参数等等。终端设备可以选择其中某些参数，例如在网络设备允许终端设备自己决定的参数上根据具体的情况进行选择。
在一些实施例中，终端设备确定第一资源分配方式后，可以利用第一资源分配方式来选择第一资源，并利用该第一资源发送第一信号。
在一些实施例中，利用第一资源分配方式确定的资源可以包括上行通信资源(即第一资源为上行通信资源)，这种情况下，利用第一资源发送的第一信号可以是上行信号。
在一些实施例中，利用第一资源分配方式确定的资源可以包括侧行通行资源(即第一资源为侧行通信资源)，这种情况下，利用第一资源发送的第一信号可以是侧行信号。
在一些实施例中，第一信号可以采用混合自动重传请求(hybrid automatic retransmission request，HARQ)的方式进行重传。
在一些实施例中，采用HARQ的方式重传第一信号的情况下，重传第一信号对应的资源分配方式与之前传输该第一信号的资源分配方式可以相同。在一些实施例中，重传第一信号对应的资源分配方式与之前传输该第一信号的资源分配方式可以不同。例如，可以与首次传输第一信号的资源分配方式相同或不同；或者，可以与上一次传输第一信号的资源分配方式相同或不同。
由于存在上述多种资源分配方式，终端设备如何从多种资源分配方式中确定第一资源分配方式是需要进一步讨论的问题。对此，本申请实施例提供的技术方案中，终端设备可以基于第一信息确定第一资源分配方式，或者随机选择第一资源分配方式。下面结合具体实施例对此进行详细介绍。
实施例一：第一资源分配方式是终端设备基于第一信息确定的
本申请实施例对第一信息的具体内容不作限定。示例性地，第一信息可以包括终端设备的本地信息和/或终端设备得到的辅助信息。其中，终端设备的本地信息可以是指终端设备内部的信息，比如终端设备内部能够掌握的信息，或者终端设备内部存储的信息等。终端设备得到的辅助信息可以是指终端设备从外部获取的信息，例如，可以包括终端设备测量得到的辅助信息，网络设备提供给终端设备的辅助信息，以及其他终端设备提供的辅助信息等。
在一些实施例中，终端设备的本地信息可以包括终端设备的应用层的数据包的相关信息，例如，可以包括应用层需要发送的数据包的大小，之前数据包发送的成功率，数据包所要求的服务质量(quality of service，QoS)参数，比如，允许的时延预算、包错误率(丢弃的数据包和总的数据包的比例)、可靠性等信息。如前文所述，在一些实施例中，在网络设备通过公共或专用信令规定某些发送参数的情况下，终端设备还可以根据上述本地信息来确定发送数据包的具体参数，比如功率、带宽等。
在一些实施例中，终端设备得到的辅助信息可以包括终端设备测量能够选择的资源所在的信道的相关信息、位于同一小区(或网络设备)内的负载分布信息、以及其他可以用于确定第一资源分配方式的相关信息。
示例性地，第一信息可以包括以下信息中的一种或多种：网络设备提供的辅助信息；终端设备对第一信道的测量结果，其中第一信道属于终端设备能够选择的资源所在的信道；终端设备所处小区的负载情况；以及终端设备采用的历史资源分配方式的性能评估结果等。
在一些实施例中，辅助信息中的一种或多种可以是由终端设备通过测量获取的，以基于对信道的测量来感受小区中资源的拥挤情况。例如，第一信息可以包括终端设备对第一信道的测量结果，第一信道属于终端设备能够选择的资源所在的信道。也就是说，终端设备可以根据终端设备对第一信道的测量结果确定第一资源分配方式。作为一种实现方式，如果测量结果为第一信道的信道占用率大于第一阈值，终端设备确定第一资源分配方式为网络设备调度资源的方式；如果测量结果为第一信道的信道占用率小于或等于第一阈值，终端设备确定第一资源分配方式为终端设备自主选择资源的方式。其中，信道占用率可以是指在一定时间段内，信道被占用的比率。比如，终端设备在10个时隙内分别对信道进行了测量，得到某个时隙内信道带宽被占用的比率，那么信道占用率可以是这10个时隙信道带宽占用比率的平均值。
不过本申请并不限定于此，在一些实施例中，终端设备获得测量结果后，可以将测量结果以及其他可以用于确定第一资源分配方式的相关信息(统称为第一信息)作为人工智能算法的输入参数，利用人工智能算法从多种资源分配方式中确定第一资源分配方式。
在一些实施例中，终端设备对第一信道的测量可以包括在发送无线信号前的预测量(在发送信号之前测量)和发送信号时的当前测量(在发送信号的当前时间测量)。终端设备在发送信号的当前时间进行测量，可以判断出是否和其他终端设备在资源上有冲突。如果没有测量到其他终端设备发送的信号，这一定程度上可以说明没有资源冲突，或者和该终端设备有冲突的终端设备距离该终端设备比较远。
在一些实施例中，假如终端设备在发送信号的当前时间测量的时候，测量到了比较严重的资源冲突，那么终端设备可以选择及时的重传，从而缩短无线信号重发的时延。
在一些实施例中，终端设备可以选择在所处网络设备的全带宽上进行测量，以提升测量准确性。在一些实施例中，终端设备可以选择在所处网络设备的部分带宽上进行测量，以节省资源。
在一些实施例中，终端设备对第一信道的测量结果可以包括：第一信道上是否有其他终端设备正在发送信号。不过本申请实施例并不限定于此，在一些实施例中，终端设备对第一信道的测量结果还可以包括：获取这些接收到的信号的强度、方向和频度等。通过测量其他终端设备的无线信号的强度、方向和频度等信息，终端设备可以基本判断出所在小区(或者所在网络设备)的拥挤程度，包括自己和其他终端设备的相对方位和远近，从而帮助自己在多种资源分配方式中选择第一资源分配方式。在一些实施例中，只要两个终端设备在方向上有足够的区分，网络设备可以比较容易地在其他维度上，比如无线信号的波束，进行区分。
考虑到终端设备不断测量周边环境会导致终端设备比较耗电，因此，在一些实施例中，辅助信息中的一种或多种可以是由网络设备提供的。这是因为，共享资源的终端设备可能会把无线信号发送给相同的网络设备(或小区)，使得网络设备能够收集到共享资源的终端设备的发送情况，比如发送的带宽，功率和所在的方位等。如此一来，网络设备可以直接向终端设备提供这些辅助信息，让终端设备可以借助这些辅助信息来帮助自己从多种资源分配方式中确定第一资源分配方式。
继续参见图5，在图5所示的方法中，在终端设备从多种资源分配方式中确定第一资源分配方式之前，该方法还可以包括步骤S505。在步骤S505，终端设备接收网络设备提供(发送)的辅助信息。网络设备提供的辅助信息可以帮助终端设备进行决策，从多种资源分配方式中确定出第一资源分配方式。
示例性地，网络设备提供的辅助信息可以包括以下信息中的一种或多种：评估信道占 用率的阈值；终端设备与其他终端设备的资源冲突的相关信息，其中，其他终端设备为与该终端设备共享资源的终端设备；第一信道的统计信息，第一信道属于终端设备能够选择的资源所在的信道；第一信道的统计信息的预测信息；与该终端设备共享资源的其他终端设备的分布信息；以及其他终端设备的分布信息的预测信息等。
在一些实施例中，网络设备可以在终端设备确定第一资源分配方式之前将上述辅助信息提供给终端设备。在一些实施例中，网络设备可以在终端设备发送第一信号之前，或者在终端设备发送第一信号的过程中，把上述辅助信息提供给终端设备。不过本申请实施例并不限定于此，在一些实施例中，网络设备还可以采取其他的方式，例如周期性或者事件触发式的方式，将上述辅助信息提供给终端设备。示例性地，事件触发式的方式可以是指上述辅助信息发生了变化(比如较大变化)的时候，网络设备向终端设备再次提供更新的辅助信息。
本申请实施例对网络设备提供辅助信息的方式不作限定。在一些实施例中，这些辅助信息可以采用高层信令(比如，无线资源控制(radio resource control，RRC)信令)的方式提供给终端设备。在一些实施例中，这些辅助信息可以采用低层信令(比如，层一/层二(L1/L2)信令)的方式提供给终端设备。
在一些实施例中，第一信息可以包括终端设备所处小区(当前小区)的负载情况。终端设备所处小区的负载情况可以是指，该终端设备所处小区(或网络设备)内的终端设备的数量。
在一些实施例中，当小区中终端设备的个数较少时，终端设备可以倾向于选择基于终端设备自主选择资源的方式。这是因为，采用这种方式可以省略终端设备和网络设备协商资源的步骤，从而能够快速地进行无线信号的发送；此外，由于小区中终端设备的个数较少，基本不会出现终端设备之间资源碰撞的问题或者出现碰撞的概率比较小，无线信号的传输可靠性也能够得到保证。
在一些实施例中，当小区中终端设备的个数较多时，终端设备可以倾向于选择基于网络设备调度资源的方式，因为这样可以避免因为资源碰撞而导致的相互干扰。
也就是说，第一资源分配方式的确定可以取决于终端设备所处小区的负载，即终端设备可以根据所处小区的负载情况确定第一资源分配方式。作为一种实现方式，如果终端设备所处小区的负载大于第二阈值，终端设备确定第一资源分配方式为网络设备调度资源的方式；如果终端设备所处小区的负载小于或等于第二阈值，终端设备确定第一资源分配方式为终端设备自主选择资源的方式。
在一些实施例中，第一资源分配方式可以是终端设备利用人工智能算法处理第一信息后确定的。示例性地，终端设备获取第一信息后，比如网络设备提供的辅助信息、终端设备对信道的测量信息、终端设备的本地信息等，可以将第一信息作为人工智能算法的参数输入至对应的算法模型中，以输出第一资源分配方式。
本申请实施例对人工智能算法的具体类型不作限定，例如，可以是非线性的机器学习算法、强化学习算法等等。
需要说明的是，终端设备可以基于上述介绍的第一信息中的一种或多种，或者组合来从多种资源分配方式中确定第一资源分配方式。
终端设备基于第一信息从多种资源分配方式中确定第一资源分配方式，能够保证确定的第一资源分配方式更符合当前无线通信系统的特征，适用性较高。
实施例二：第一资源分配方式是终端设备随机选择的
终端设备可以按照一定的概率，例如采用随机选择的方式，从多种资源分配方式中确定第一资源分配方式。
在一些实施例中，终端设备可以在初始与网络设备进行上行同步(比如，终端设备刚开机)的情况下，随机选择第一资源分配方式。
在一些实施例中，终端设备随机选择第一资源分配方式后，可以评估使用该第一资源分配方式的性能，以便后续根据历史资源分配方式的性能评估结果从多种资源分配方式中确定第一资源分配方式。
本申请实施例对终端设备的性能评估参数不作具体限定，例如，可以包括信号发送的时延，信号发送状态为成功还是失败，信号重传的次数等等。
在一些实施例中，终端设备根据历史资源分配方式的性能评估结果从多种资源分配方式中确定第一资源分配方式时，可以总是选择性能比较好的那种方式。在一些实施例中，终端设备可以在大多数情况下选择性能较好的方式，偶尔也可以选择性能次佳的方式。
为了便于理解，下面结合几个具体示例，对本申请实施例的技术方案进行介绍。下面示例是以终端设备向网络设备发送上行信号为例进行介绍的，不过本申请的技术方案也可以应用于终端设备之间发送侧行信号。
示例1：终端设备随机选择第一资源分配方式
图6为本申请另一实施例提供的用于确定资源分配方式的方法的流程示意图。参见图6，图6的方法可以包括步骤S610至步骤S650。
在步骤S610，终端设备随机从多种资源分配方式中确定第一资源分配方式。
终端设备可以按照一定的概率，从多种资源分配方式中确定第一资源分配方式，例如，确定第一资源分配方式为网络设备调度资源的方式，或者确定第一资源分配方式为终端设备自主选择资源的方式。
在步骤S620，终端设备基于第一资源分配方式确定第一资源，并利用第一资源发送第一信号。
在步骤S630，终端设备根据网络设备的反馈，评估第一资源分配方式的性能。
在一些实施例中，终端设备可以根据网络设备的反馈，确定第一信号是否发送成功。
在一些实施例中，如果第一信号发送成功，终端设备还可以获知第一资源分配方式所能达到的具体性能，例如，信号发送的时延等。
在步骤S640，终端设备随机尝试一段时间后，再确定后续的资源分配方式。
比如，终端设备可以总是选择性能较好的那种方式；或者，终端设备可以在大多数情况下选择性能较好的方式，偶尔也可以选择性能次佳的方式。
在步骤S650，终端设备继续评估当前采用的第一资源分配方式的性能。
在一些实施例中，如果当前采用的第一资源分配方式的性能出现较大波动，则可以回到步骤S610，再次重新选择第一资源分配方式。
示例2：终端设备基于信道测量确定第一资源分配方式
图7为本申请又一实施例提供的用于确定资源分配方式的方法的流程示意图。参见图7，图7的方法可以包括步骤S710至步骤S750。
在步骤S710，终端设备测量能够选择的资源所在的信道。例如，终端设备可以测量信道的信道占用率。
在步骤S720，终端设备基于信道的测量结果，确定第一资源分配方式。
例如，测量结果为信道的信道占用率比较低，那么可以确定第一资源分配方式为终端设备自主选择资源的方式。或者，测量结果为信道的信道占用率比较高，那么可以确定第一资源分配方式为网络设备调度资源的方式。
在步骤S730，终端设备基于第一资源分配方式确定第一资源，并利用第一资源发送第一信号。
在步骤S740，如果终端设备确定第一资源分配方式为终端设备自主选择资源的方式，则终端设备在发送第一信号的时间点(比如，无线帧、子帧、时隙、符号等)上，继续在自己使用的资源所在的带宽上进行测量，以确认是否和其他终端设备发送的信号发生了冲突。
在步骤S750，如果没有产生冲突或者冲突不严重，则终端设备等待网络设备的反馈；如果冲突严重，终端设备选择是否在较短时间内重传第一信号。
在一些实施例中，如果冲突严重，终端设备可以选择在较短时间内重传第一信号，例如，立即或还未收到网络设备的反馈前重传第一信号。在一些实施例中，终端设备重传第一信号时，可以继续采用终端设备自主选择资源的方式确定重传第一信号的资源。在一些实施例中，终端设备重传第一信号时，可以采用新的资源分配方式(比如，网络设备调度资源的方式)确定重传第一信号的资源。
示例3：终端设备基于网络设备提供的辅助信息确定第一资源分配方式
图8为本申请又一实施例提供的用于确定资源分配方式的方法的流程示意图。参见图8，图8的方法可以包括步骤S810至步骤S830。
在步骤S810，网络设备向终端设备发送辅助信息。
网络设备发送的辅助信息可以是以下信息中的一种或多种：终端设备用来判断信道占有率高低的阈值；终端设备和其他终端设备发送的信号之间的冲突严重程度的阈值；过去或当前关于信道的统计信息，比如信道占用率；信道的统计信息的预测信息；共享资源的其他终端设备在网络设备(或小区)内的分布信息；以及这些分布信息的预测信息等。
