通信方法、终端设备和网络设备 技术领域
本申请涉及通信领域，并且更具体地，涉及一种通信方法、终端设备和网络设备。
背景技术
在长期演进(Long Term Evolution，LTE)系统中，当需要传输上行数据时，用户设备(User Equipment，UE)采用上行调度请求(Scheduling Request，SR)机制。UE通过发送上行调度请求给基站，告知基站UE需要上行资源进行数据传输。基站接收到UE的调度请求后，给UE分配一定的资源，UE在这些分配的资源上进行数据传输。但是该种机制导致大量的信令开销。
为了解决上述问题，可以采用基于竞争的方式进行数据的传输。也即UE无需通过调度请求方式请求基站分配资源进行数据传输，而是从资源池中随机选择进行数据的传输。
基于竞争的方式进行数据传输，资源的选择对整个通信性能的影响比较重要，因此，如何选择合适的资源是基于竞争的方式进行数据的传输的技术中亟待解决的问题。

应理解，图3所示的步骤230和240可以择一存在，也可以均存在。
因此，在本申请实施例中，终端设备根据资源池的资源使用状况，从至少两个资源池中确定目标资源池，从而可以结合资源池的具体使用情况选择目标资源池，可以尽量避免在基于竞争的传输过程中，对其他终端设备造成的影响，或避免其他终端设备对自身数据传输所造成的影响。
图4是根据本申请实施例的通信方法300的示意性流程图。如图4所示，该方法包括以下内容。
在310中，终端设备根据该终端设备与网络设备之间的下行路径损耗，以及选择用于发送数据的目标资源池，确定第一发射功率。
在320中，终端设备根据该第一发射功率，通过所述目标资源池中的资源向网络设备发送数据。
可选地，在本申请实施例中，终端设备根据该终端设备与该网络设备之间的下行路径损耗，确定第二发射功率；根据该目标资源池对应的调整参数，对该第二发射功率进行调整，得到该第一发射功率。
可选地，在本申请实施例中，终端设备可以根据资源池与调整参数的对应关系，确定该目标资源池对应的调整参数。
例如，资源池1对应的调整参数是10db，资源池2对应的调整参数是30db，资源池3对应的调整参数是-10db，则终端设备在根据路径损耗得到的发射功率是70db，如果选择资源池1，则终端设备用于发送上行数据的发射功率是80db，如果选择资源池2，则终端设备用于发送上行数据的发射功率是100db，如果选择资源池3，则终端设备用于发送上行数据的发射功率60db。
可选地，在本申请实施例中，如图5所示，网络设备可以向终端设备发送该资源池与调整参数的对应关系(330)，则终端设备可以根据网络设备发射的对应关系，确定用于对发射功率进行调整的调整参数。
可选地，资源池与调整参数的对应关系可以是网络设备根据资源池的状况参数确定的，例如资源池的资源使用率和资源冲突率等。
例如，对于资源使用率小于等于30％的资源池，调整参数是0db，对于资源使用率在小于等于50％且大于30％的资源池，则调整参数是10db，对于资源使用率大于50％的资源池，则调整参数是30db，在终端设备根据该路径损耗确定发射功率后，可以将确定的发射功率减去该调整参数。
可选地，在本申请实施例中，终端设备可以根据资源池的状况参数与调整参数的对应关系，以及目标资源池的状况参数，确定目标资源池对应的调整参数。
例如，终端设备在选择资源池2，该资源池2的资源使用率大于等于50％且大于30％，则终端设备可以选择与该使用率匹配的调整参数，例如10db，则终端设备可以在根据下行路径损耗得到的发射功率的基础上减去10db，从而得到最终的发射功率。
可选地，如图5所示，网络设备可以向终端设备发送资源池的状况参数，以及资源池的状况参数与调整参数的对应关系(340)。
可选地，在本申请实施例中，该终端设备根据该目标资源池、该终端设备与该网络设备之间的下行路径损耗，以及资源池、下行路径损耗与发射功率三者之间的对应关系，确定该第一发射功率。
具体地说，对于不同的资源池，可以对应不同的下行路径损耗与发射功率的对应关系，终端设备在选择目标资源池之后，可以根据该目标资源池，确定与该目标资源池对应的下行路径损耗与发射功率的对应关系，从而根据确定的该下行路径损耗与发射功率的对应关系，以及确定的下行路径损耗，确定发射功率。
换句话说，相同的下行路径损耗，对于不同的资源池可以对应不同的发射功率。
例如，对于相同的路径损耗，资源池1对应的发射功率要低于资源池2的发射功率。
可选地，资源池、下行路径损耗与发射功率三者之间的对应关系可以是网络设备根据资源池的状况参数确定的，例如，资源池的资源使用率和碰撞率。
例如，资源池1的资源使用率是70％,资源池2的使用率是30％,那对于相同的路径损耗，基站为资源池1配置的发射功率要低于为资源池2配置的发射功率。
可选地，在本申请实施例中，如图5所示，网络设备可以向终端设备发送资源池、下行路径损耗与发射功率三者之间的对应关系(350)。
可选地，在本申请实施例中，终端设备根据该目标资源池的状况参数，该终端设备与该网络设备之间的下行路径损耗，以及根据下行路径损耗、发 射功率和资源池的状况参数三者之间的对应关系，确定该第一发射功率。
具体地说，资源池的不同状况参数的取值(或范围)，对应不同的下行路径损耗与发射功率的对应关系，终端设备可以根据目标资源池的状况参数，选择下行路径损耗与发射功率的对应关系，从而根据确定的该下行路径损耗与发射功率的对应关系，以及确定的下行路径损耗，确定发射功率。
换句话说，相同的下行路径损耗，对于不同的资源池状况参数的取值(或范围)可以对应不同的发射功率。
资源池1的资源使用率是70％,资源池2的使用率是30％,那对于相同的路径损耗，资源池1对应的发射功率要低于为资源池2对应的发射功率。
可选地，在本申请实施例中，如图5所示，网络设备可以向终端设备发送下行路径损耗、发射功率和资源池的状况参数三者之间的对应关系，以及资源池的状况参数(360)。
应理解，图5所示的步骤330-360可以择一存在，也可以均存在或部分存在。
因此，在本申请实施例中，终端设备根据该终端设备与网络设备之间的下行路径损耗，以及选择用于发送数据的目标资源池，确定发射功率，发射功率的确定可以结合选择的资源池的具体情况(例如，资源使用状况)，从而可以选择更适合所选择的资源池的发射功率。
图6是根据本申请实施例的通信方法400的示意性流程图。如图6所示，该通信方法400包括以下内容。
在410中，终端设备根据该终端设备与网络设备之间的下行路径损耗，确定目标资源池。
该终端设备根据与该网络设备之间的下行路径损耗，以及根据下行路径损耗与资源池的对应关系，确定该目标资源池。
例如，资源池1，对应路径损耗在-20～-30dB；资源池2，对应路径损耗在-30～-40dB。则下行路径损耗在-20～-30dB的终端设备，可以选择资源池1，下行路径损耗在-30～-40dB的终端设备，可以选择资源池2。
可选地，如图7所示，网络设备可以向终端设备发送下行路径损耗与资源池的对应关系(430)。从而，终端设备可以利用该对应关系，确定目标资源池。
在420中，该终端设备利用该目标资源池的资源，与网络设备进行通信。
因此，在本申请实施例中，终端设备可以根据下行路径损耗选择目标资源池，从而可以实现下行路径损耗相似的终端选择相同的资源池，由于可以根据下行路径损耗选择发射功率，从而可以实现发射功率近似的终端选择相同的资源池，从而可以避免由于发射功率相差太大的终端选择相同的资源池所造成的远近效应。
