Description

一种数据发送方法和装置 技术领域
本发明涉及通信领域，尤其涉及一种数据发送方法和装置。
背景技术
在通信系统中，时延可以定义为单程时间(one-trip time,OTT)，指数据由发送端发送到接收端接收所经历的时间；另一种定义方式为往返时间(round-trip time,RTT)，指数据由发送端发送到发送端接收到反馈信息所经历的时间。此外，时延又可以分控制面时延和用户面时延。控制面时延指用户设备与基站之间由空闲态(IDLE)转换到连接态(CONNECTED)所经历的时间，在第五代移动通信技术(5-Generation，5G)系统中一般要求不大于10ms；用户面时延指用户应用层的数据或消息从进入无线协议层的层2或层3的业务数据单元(SDU Service Data Unit)，到从相应的层解码出来所经历的时间，如图1所示，以用户设备(User Equipment，UE)向基站(Evolved Node B，eNB)发送数据为例，用户面的时延为UE侧分组数据汇聚协议业务数据单元(Packet Data Convergence Protocol Service Data Unit，PDCP SDU)进入PDCP层到基站侧PDCP SDU离开PDCP层，在第五代移动通信技术5G系统中一般要求不大于0.5ms。
现有技术中，对于用户面时延来说，为了满足超低时延，提出了一种基于竞争资源的上行数据发送方法，如图2所示，首先基站为其信号覆盖范围内的UE分配多个公共的上行资源，当UE有数据产生需要发送给基站时，可以直接使用上述基站分配的上行资源发送数据，减少UE请求资源然后再获取到相应资源的过程的时延。然而，当多个UE使用同一个上行资源发送数据时便会产生资源冲突。具体来说，在一种可能的情况中，如图2的图a)所示，UE1从分配的上行资源中选择资源并发送上行数据，这部分上行资源只有 UE1使用，此时没有发生资源冲突。在另一种可能的情况中，如图2的图b)所示，UE1和UE2从分配的上行资源中选择相同的资源发送上行数据，这部分上行资源同时被两个UE使用，此时会发生资源冲突，基站可能不能成功接收UE1和UE2发送的数据，使得UE1和UE2需要重新发送数据，导致UE1和UE2向基站发送上行数据的时延增加。
发明内容
本发明提供一种数据发送方法和装置，能够减少重传数据的终端数量，从而从整体上减少数据发送的时延。
一方面，提供一种数据发送方法，包括：网络设备向终端发送功率配置信息，功率配置信息包括功率信息和终端状态信息的一一对应关系，功率配置信息用于使终端获取发送数据时的发射功率；网络设备接收终端发送的数据，数据的发射功率是终端根据功率配置信息确定的；其中，终端状态信息包括终端发送的数据的业务类型、终端发送的数据的优先级、终端对无线环境的测量信息的至少一种；功率信息包括网络设备的期望接收功率、终端与网络设备进行通信时的发射功率、终端进行D2D通信时的发射功率中的至少一种。这样一来，根据对应关系为不同的业务类型的数据或不同的优先级的数据或不同的无线环境对应的数据设置了不同的功率信息，即不同终端在发送数据时采用不同的功率信息，网络设备或终端就可以在多个终端基于竞争资源的数据发送所发生的资源冲突的情况下区别接收不同终端发送的数据，保证部分UE发送的数据的接收成功率，减少重传数据的终端数量，从而从整体上减少数据发送的时延。
在一种可能的设计中，还包括:当终端状态信息包括终端发送的数据的业务类型或终端发送的数据的优先级时，方法还包括:网络设备接收网络设备覆盖范围内的终端发送的数据的业务类型或数据的优先级；或网络设备接收核心网发送的不同的业务类型对应的服 务质量QoS信息，进而根据QoS信息确定数据的业务类型或数据的优先级。也即，网络设备获取的数据的业务类型或数据的优先级可以是终端发送的，也可以是核心网发送的，此外，通过关联数据的业务类型或数据的优先级，可以为不同的业务类型的数据或不同的优先级的数据确定不同的功率信息，可以保证部分数据的传输效率或部分业务的QoS。
在一种可能的设计中，还包括：网络设备向终端发送资源配置消息，资源配置消息包括终端的参考信号接收功率RSRP范围和时频资源配置参数，或资源配置消息包括终端的参考信号接收质量RSRQ范围和所述时频资源配置参数,时频资源配置参数包括物理资源块PRB参数和子帧参数，或时频资源配置参数包括PRB参数和系统帧参数。资源配置消息可以为不同无线环境下的终端配置不同的上行资源，假设两个无线环境不同的终端，即RSRP范围不同时两个终端发送数据时，两个终端确定的时频资源不同，以避免网络设备接收两个终端发送的数据时产生冲突。具体来说，如图2c，若终端1的业务类型优先级高，对应的发射功率也高，终端2的业务类型优先级低，对应的发射功率也低，但是由于终端2的无线环境优于终端1的无线环境，即终端2的RSRP范围大于终端1的RSRP范围，终端1的路损大于终端2的路损，会使得终端2发送的数据到达网络设备时的接收功率可能与终端1发送的数据到达网络设备时的接收功率相同，即使终端1和终端2的发射功率不同，网络设备也无法接收到达网络设备时接收功率相同的两个终端的数据，但是如果给无线环境不同的两个终端配置的时频资源不同，可以避免由于资源冲突网络设备不能接收终端1和终端2发送的数据的问题。这样一来，避免了配置了较高发射功率的数据到达网络设备或对端时的功率与配置了较低发射功率的数据到达网络设备或对端时的功率一致，从而导致网络设备或对端不能成功接收一部分数据的情况。
在一种可能的设计中，功率配置信息还包括幅度值，幅度值用于使终端确定重传数据时的发射功率，重传数据时的发射功率为前 一次发送数据时的发射功率与幅度值之和。这样一来，重传时终端发送数据时使用的发射功率更大，更有可能成功发射数据，从而降低重传时延。
另一方面，提供一种数据发送方法，包括：终端接收网络设备发送的功率配置信息，功率配置信息包括功率信息和终端状态信息的一一对应关系；终端根据功率配置信息确定终端发送数据时的发射功率；其中，终端状态信息包括终端发送的数据的业务类型、终端发送的数据的优先级、终端对无线环境的测量信息的至少一种；功率信息包括网络设备的期望接收功率、终端与网络设备进行通信时终端的发射功率、终端进行D2D通信时的发射功率中的至少一种。这样一来，根据对应关系为不同的业务类型对应的数据或不同的优先级对应的数据或不同的无线环境对应的数据设置了不同的功率信息，即不同的终端发送数据时采用不同的功率信息，就可以使网络设备或对端在多个终端基于竞争资源的数据发送过程中所发生的资源冲突的情况下能够接收部分终端的数据，保证部分数据的接收成功率，减少重传数据的终端数量，从而从整体上减少数据发送的时延。
在一种可能的设计中，当终端状态信息包括终端发送的数据的业务类型或数据的优先级，功率信息包括网络设备的期望接收功率时，终端根据功率配置信息确定终端发送数据时的发射功率包括：终端根据终端发送的数据的业务类型对应的网络设备的期望接收功率或终端根据终端发送的数据的优先级对应的网络设备的期望接收功率确定将数据发送至网络设备的期望接收功率；终端根据将数据发送至网络设备的期望接收功率和路损值确定终端发送数据时的发射功率；或，当终端状态信息包括终端发送的数据的业务类型或终端发送数据的优先级，功率信息包括终端与网络设备进行通信时终端的发射功率时，终端根据功率配置信息确定终端发送数据时的发射功率包括：终端根据终端发送的数据的业务类型对应的终端的发射功率或所述终端根据所述终端发送数据的优先级对应的终端的发 射功率确定终端发送数据时的发射功率。
在一种可能的设计中，当终端状态信息包括终端对无线环境的测量信息，测量信息包括终端测量网络设备参考信号接收功率RSRP或参考信号接收质量RSRQ，功率信息包括网络设备的期望接收功率时，终端根据功率配置信息确定终端发送数据时的发射功率包括：终端根据无线环境的测量信息对应的网络设备的期望接收功率确定将数据发送至网络设备的期望接收功率；终端根据将数据发送至网络设备的期望接收功率和路损值确定终端发送数据时的发射功率；或，当终端状态信息包括终端对无线环境的测量信息，测量信息包括终端测量网络设备的参考信号接收功率RSRP或参考信号接收质量RSRQ，功率信息包括终端与网络设备进行通信时终端的发射功率时，终端根据功率配置信息确定终端发送数据时的发射功率包括：终端将终端对无线环境的测量信息对应的终端的发射功率确定为终端发送数据时的发射功率。
在一种可能的设计中，当功率信息包括终端进行D2D通信时的发射功率，终端状态信息包括终端发送的数据的业务类型或终端发送的数据的优先级或终端对无线环境的测量信息时，终端对无线环境的测量信息包括终端测量对端发送的参考信号的RSRP或RSRQ，其中终端与对端进行D2D通信，终端根据功率配置信息确定终端发送数据时的发射功率包括：终端将业务类型对应的终端进行D2D通信时的发射功率或数据的优先级对应的终端进行D2D通信时的发射功率或终端对无线环境的测量信息对应的终端进行D2D通信时的发射功率确定为终端发送数据时的发射功率。这样一来，可以使终端在发送不同业务类型对应的数据或不同优先级对应的数据时可以采用不同的发射功率，保证了在发生资源冲突时，在D2D通信中，接收数据的终端可以接收到一部分发送数据的终端发送的数据，减少重传数据的终端数量。
在一种可能的设计中，还包括：终端接收网络设备发送的资源 配置消息，资源配置消息包括终端的参考信号接收功率RSRP范围和时频资源配置参数，或资源配置消息包括所述终端的参考信号接收质量RSRQ范围和时频资源配置参数，时频资源配置参数包括物理资源块PRB参数和子帧参数，或时频资源配置参数包括PRB参数和系统帧参数；终端根据资源配置消息确定终端发送数据的上行资源。资源配置消息可以为不同无线环境下的终端配置不同的上行资源，假设两个无线环境不同的终端，即RSRP范围不同的两个终端发送数据时，两个终端确定的时频资源不同，可以避免网络设备接收两个终端发送的数据时产生冲突。
在一种可能的设计中，还包括：终端向网络设备发送终端发送的数据的业务类型或终端发送的数据的优先级。
在一种可能的设计中，还包括：若终端确定网络设备未接收到数据，或终端确定进行D2D通信时的对端未接收到数据，则终端确定重传数据时的发射功率，重传数据时的发射功率为前一次发送数据时的发射功率与预设的幅度值之和。这样一来，重传时终端发送数据时使用的发射功率更大，更有可能成功发射数据，从而降低重传时延。

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清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例可应用于5G的无线接入技术(Radio Access Technology,RAT)，可以包括以下应用场景：大量机器类型通信(Massive Machine Type Communication,eMTC)，和超可靠和超低时延通信(Ultra Reliable and Low Latency Communication,URLLC)。本发明实施例可应用于eMTC和URLLC中基于竞争资源的数据发送的过程，也可应用于其他数据发送过程中，本申请不做限定。
本发明实施例可应用的网络架构可以包括基站和基站覆盖范围下的多个UE，可以是基站与UE之间的通信，比如说UE向基站发送上行数据，如图3所示，UE在发送上行数据时，若为基于竞争资源的上行数据发送过程，多个UE可以使用公共的上行资源向基站发送数据；也可以是UE与UE之间的通信，如图4所示，不同的成对的(pair)UE发送设备到设备(Device-to-Device，D2D)直接通信数据时，若为基于竞争资源的数据发送过程，进行D2D通信的UE可以使用公共的资源发送数据。
在本发明实施例中，终端可以是用户设备UE，UE可以是手机、智能终端、多媒体设备、流媒体设备、可穿戴设备、智能电表、智能水表等。在本发明实施例中，网络设备可以是基站，基站可以是长期演进(Long Term Evolution，LTE)中UE和演进的核心网(Evolved Packet Core,EPC)之间的桥梁，基站之间通过X2接口进行连接，主要功能有：无线资源管理、互联网协议地址(Internet Protocol Address,IP)头压缩及用户数据流加密、UE附着时的移动管理实体(Mobile Managenment Entity,MME)选择、路由用户面数据至服务网 关(Serving Gateway,S-GW)、寻呼消息的组织和发送、广播消息的组织和发送、以移动性或调度为目的测量及测量报告配置等。
图5为本发明实施例中基站的一种内部结构示意图，在本发明中，基站可以包括处理模块501、通讯模块502、存储模块503。其中，处理模块501用于控制基站的各部分硬件装置和应用程序软件等；通讯模块502用于可使用LTE、5G RAT、wifi等通讯方式接受其它设备发送的指令，也可以将基站的数据发送给其它设备；存储模块503用于执行基站的软件程序的存储、数据的存储和软件的运行等。

下面以终端为用户设备UE，且基于竞争资源的数据发送为例对本发明实施例进行说明。本发明的基本思想是：基站向所覆盖的UE发送功率配置信息；当UE生成上行数据时，首先判断该数据的业务类型或优先级，或判断自身的无线环境，然后根据功率配置信息为需要发送的数据配置相应的发射功率，这样在UE通过基站分配的资源配置消息确定上行资源或通信资源并发送数据时，若多个UE使用相同的上行资源或通信资源发送数据时，多个UE可根据确定的不同的发射功率向基站或对端发送数据，使得保证基站或对端可以接收到部分接收功率高的UE的数据，对端为与终端进行D2D通信时的另一个终端，保证一部分UE数据的接收成功率，从而减少了重传数据的UE的数量，从整体上降低了数据发送的时延。
在本发明实施例中，基站除了通过配置不同的发射功率来区别 UE以外，还可以通过配置不同的调制与编码策略(Modulation and Coding Scheme,MCS)或配置不同的加扰方式来区别UE，以减少重传数据的UE的数量，从整体上降低了数据发送的时延。
本发明实施例提供一种数据发送方法，如图7所示，包括：
701、基站向UE发送功率配置信息，功率配置信息包括功率信息和UE状态信息的一一对应关系，功率配置信息用于使UE获取发送数据时的发射功率。
其中，UE状态信息包括UE发送的数据的业务类型、UE发送的数据的优先级、UE对无线环境的测量信息的至少一种；
功率信息包括基站的期望接收功率、UE与基站进行通信时UE的发射功率、UE进行D2D通信时的发射功率中的至少一种。
UE发送的数据的业务类型可以包括语音业务、漫游业务、短信业务、邮件业务、公共安全类业务和上网业务等。
示例性的，若基站配置基站的期望接收功率与UE发送数据的优先级对应，其对应关系可以是优先级高的数据配置较高的期望接收功率，优先级低的数据配置较低的期望接收功率；假设用数字表示数据的优先级，若表示数据的优先级的数字越大，则优先级越低，比如说，UE1发送的数据的优先级为1，UE2发送的数据的优先级为2，则为UE2配置的期望接收功率低于为UE1配置的期望接收功率。
若基站配置基站的期望接收功率与UE的业务类型对应，其对应关系可以是按照业务类型的重要程度对应不同的期望接收功率，重要程度高的业务类型对应较高的期望接收功率，重要程度低的业务类型对应较低的期望接收功率；假设用数字表示数据的业务类型，若表示数据的业务类型的数字越大，则业务类型的重要程度越低，比如说，UE1发送的数据的业务类型为1，UE2发送的数据的业务类型为2，则为UE2配置的期望接收功率低于为UE1配置的期望接 收功率。
若基站配置基站的期望接收功率与UE对无线环境的测量信息对应，其对应关系可以是基站的期望接收功率与UE测量基站发送的参考信号的接收功率(Reference Signal Receiving Power，RSRP)的对应关系，RSRP值越大，基站的期望接收功率越大；或者，若基站配置基站的期望接收功率与UE对无线环境的测量信息对应，其对应关系可以是基站的期望接收功率与参考信号接收质量(Reference Signal Receiving Quality，RSRQ)的对应关系，RSRQ越大，基站的期望接收功率越大；假设用分贝毫瓦dBm作为RSRP或RSRQ的单位，若UE1测量基站发送的参考信号的RSRP或RSRQ为-100dBm，UE1测量基站发送的参考信号的RSRP或RSRQ为-110dBm，则为UE2配置的期望接收功率低于为UE1配置的期望接收功率。
若UE与基站进行通信时UE的发射功率与UE发送数据的优先级对应，其对应关系可以为优先级高的数据配置较高的发射功率，优先级低的数据配置较低的发射功率；假设用数字表示数据的优先级，若表示数据的优先级的数字越大，则优先级越低，比如说，UE1发送的数据的优先级为4，UE2发送的数据的优先级为7，则为UE2配置的与基站进行通信时的发射功率低于为UE1配置的与基站进行通信时的发射功率。
若UE的与基站进行通信时的发射功率与UE发送的数据的业务类型对应，其对应关系可以是按照业务类型的重要程度对应不同的发射功率，重要程度高的业务类型对应较高的发射功率，重要程度低的业务类型对应较低的发射功率；假设用数字表示UE发送的数据的业务类型，若表示UE发送的数据的业务类型的数字越大，则业务类型的重要程度越低，比如说，UE1发送的数据的业务类型为2，UE2发送的数据的业务类型为5，则为UE2配置的与基站进行通信时的发射功率低于为UE1配置的与基站进行通信时的发射功率。
若UE与基站进行通信时UE的发射功率与UE对无线环境的测量信息对应，其对应关系可以是UE的发射功率与UE测量基站的RSRP的对应关系，RSRP值越大，UE的发射功率越大；或者，若UE的发射功率与UE对无线环境的测量信息对应，其对应关系可以是UE的发射功率与RSRQ的对应关系，RSRQ越大，UE的发射功率越大；假设用分贝毫瓦dBm作为RSRP或RSRQ的单位，若UE1测量基站发送的参考信号的RSRP或RSRQ为-100dBm，UE1测量基站发送的参考信号的RSRP或RSRQ为-110dBm，则为UE2配置的发射功率低于为UE1配置的发射功率。
若UE进行D2D通信时的发射功率与D2D数据的优先级对应，其对应关系可以是优先级高的数据配置较高的发射功率，优先级低的数据配置较低的发射功率；假设用数字表示数据的优先级，若表示数据的优先级的数字越大，则优先级越低，比如说，UE1发送的数据的优先级为4，UE2发送的数据的优先级为7，则为UE2配置的进行D2D通信时的发射功率低于为UE1配置进行D2D通信时的发射功率。
若UE进行D2D通信时的发射功率与UE发送的数据的业务类型对应，其对应关系可以是按照业务类型的重要程度对应不同的发射功率，重要程度高的业务类型对应较高的发射功率，重要程度低的业务类型对应较低的发射功率；假设用数字表示数据的业务类型，若表示数据的业务类型的数字越大，则业务类型的重要程度越低，比如说，UE1发送的数据的业务类型为2，UE2发送的数据的业务类型为5，则为UE2配置的进行D2D通信时的发射功率低于为UE1配置的进行D2D通信时的发射功率。
若UE进行D2D通信时的发射功率与UE对无线环境的测量信息对应，其对应关系可以是UE进行D2D通信时的发射功率与UE测量对端UE的RSRP的对应关系，RSRP值越大，UE进行D2D通信时的发射功率越大；或者，UE进行D2D通信时的发射功率与UE 对无线环境的测量信息的对应关系可以是UE进行D2D通信时的发射功率与对端UE的RSRQ的对应关系，RSRQ越大，UE进行D2D通信时的发射功率越大；假设用分贝毫瓦dBm作为RSRP或RSRQ的单位，若UE1测量基站发送的参考信号的RSRP或RSRQ为-90dBm，UE1测量基站发送的参考信号的RSRP或RSRQ为-100dBm，则为UE2配置的进行D2D通信时的发射功率低于为UE1配置的进行D2D通信时的发射功率。
702、UE根据功率配置信息确定UE发送数据时的发射功率。
如果功率配置信息包括任一功率信息和任一终端状态信息的对应关系，可以先判断需要发送数据的UE的终端状态信息，再根据对应关系确定以何种功率信息发送数据。
具体地，如果功率配置信息包括基站的期望接收功率与UE发送的数据的业务类型的对应关系，那么UE先判断需要发送的数据的业务类型，然后根据与需要发送的数据的业务类型对应的基站的期望接收功率确定UE发送数据时的发射功率；
如果功率配置信息包括基站的期望接收功率与UE发送的数据的优先级的对应关系，那么UE先判断需要发送的数据的优先级，然后根据与需要发送的数据的优先级对应的基站的期望接收功率确定UE发送数据时的发射功率；
如果功率配置信息包括基站的期望接收功率与UE对无线环境的测量信息的对应关系，那么UE可以在确定UE对无线环境的测量信息后，根据与UE对无线环境的测量信息对应的基站的期望接收功率确定UE发送数据时的发射功率；
如果功率配置信息包括与基站进行通信时UE的发射功率与UE的业务类型的对应关系，那么UE先判断需要发送的数据的业务类型，然后根据与需要发送的数据的业务类型对应的UE的发射功率确定UE发送数据时的发射功率；
如果功率配置信息包括与基站进行通信时UE的发射功率与UE发送的数据的优先级的对应关系，那么UE先判断需要发送的数据的优先级，然后根据与需要发送的数据的优先级对应的UE的发射功率确定UE发送数据时的发射功率；
如果功率配置信息包括与基站进行通信时UE的发射功率与UE对无线环境的测量信息的对应关系，那么UE可以在确定UE对无线环境的测量信息后，根据与UE对无线环境的测量信息对应的与基站进行通信时UE的发射功率确定UE发送数据时的发射功率；
如果功率配置信息包括UE进行D2D通信时的发射功率与业务类型的对应关系或包括UE进行D2D通信时的发射功率与数据的优先级的对应关系，那么在UE判断需要发送的数据的业务类型或数据的优先级后，根据需要发送的数据的业务类型与UE进行D2D通信时的发射功率的对应关系或数据的优先级与UE进行D2D通信时的发射功率的对应关系确定UE发送数据时的发射功率。
如果功率配置信息包括UE进行D2D通信时的发射功率与对无线环境的测量信息的对应关系，那么在UE先确定对无线环境的测量信息，再根据与UE对无线环境的测量信息对应的与基站进行通信时UE的发射功率确定确定UE发送数据时的发射功率。
703、UE向基站发送数据。
这样一来，多个UE在基站分配的同一个上行资源或通信资源上发送数据时，即在发生资源冲突时，UE可以根据对应关系为不同的业务类型对应的数据确定不同的发射功率；或UE可以根据对应关系为不同优先级对应的数据确定不同的发射功率；或UE可以根据对应关系为不同的无线环境对应的数据确定不同的发射功率，就可以保证优先级较高的数据或业务类型较重要的数据发送成功，或保证所处的无线环境较好的UE的数据发送成功，可以减少重传数据的UE数量，从而从整体上减少数据发送的时延。
下面对UE发送上行数据，功率配置信息包括基站的期望接收 功率与UE发送的数据的优先级的对应关系的情况进行说明。
本发明实施例提供一种数据发送方法，如图8所示，包括：
801、基站接收并统计基站覆盖范围内的UE发送的数据的优先级；或基站接收核心网发送的不同的业务对应的服务质量(Quality of Service，QoS)信息，进而根据QoS信息确定数据的优先级。
UE向基站发送优先级可以是一次将自身所有的数据的优先级都发送给基站，也可以是在发送数据前将所需发送数据的优先级发送给基站。
Qos信息可以包括UE与基站之间发送数据的时延，或UE与基站之间发送数据的丢包率等。基站根据核心网发送的QoS信息的时延、丢包率等指标来确定数据的优先级，可以是时延要求越高，数据的优先级越高，也就是说，时延越长，数据的优先级越低，时延越短，数据的优先级越高。
802、基站向UE发送功率配置信息，功率配置信息包括基站的期望接收功率与UE发送数据的优先级的对应关系，功率配置信息用于使UE获取发送数据时的发射功率。
基站可以周期性的以广播形式发送功率配置信息，可以使得最近进入到基站覆盖范围内的UE及时接收到该功率配置信息，也可以使得基站覆盖范围内的UE及时接收到最新的功率配置信息，还可以使得UE产生新的业务类型或数据的优先级时，基站可以及时为功率配置信息加入新的对应关系。
基站的期望接收功率可以是基站根据自身的接收能力和解码能力确定的。例如基站在确定自身的最大接收功率和最小接收功率后，根据相同或不同的间隔将最大接收功率与最小接收功率之间的功率范围划分为不同功率等级，不同的功率等级对应不同的业务类型或不同的数据的优先级。基站的接收能力和解码能力与基站的硬件设置和软件设置有关。
具体地，基站可以配置如表1形式的功率配置列表，优先级“0”表示最高优先级，数字越大，优先级越低，对应的基站的期望接收功率越小。
表1
序号 数据的优先级 基站的期望接收功率
1 3 -110dBm
2 0 -100dBm
3 5 -120dBm
…… …… ……
其中，表示不同的数据的优先级的数字也可以表示不同的业务类型，例如，可以是0表示语音业务，3表示漫游业务，5表示短信业务。
举例来说，若功率配置列表如表1，UE需发送的数据的优先级是5，则获取基站期望的接收功率为-120dBm，根据基站的期望接收功率-120dBm再加上路损值即可计算得到UE发送数据时的发射功率。
一种可替换的方式可以为：功率配置信息包括基站的期望接收功率与UE的业务类型的对应关系。不同业务类型的重要程度不同，即可以为不同的业务类型配置不同的期望接收功率，重要程度高的业务类型的期望接收功率高，重要程度低的业务类型的期望接收功率低；举例来说，若用不同的数字表示数据的业务类型，UE需发送的数据的业务类型是5，基站配置的功率信息中与业务类型5对应的基站的期望接收功率为-120dBm，则UE根据基站的期望接收功率-120dBm再加上路损值即可计算得到UE发送数据时的发射功率。
另一种可替换的方式可以为：功率配置信息包括UE的发射功率与UE发送的数据的业务类型的对应关系。UE发送的数据的业务类型重要程度高时配置的UE的发射功率高，UE发送的数据的业务类型重要程度低时配置的UE的发射功率低；举例来说，若用不同 的数字表示数据的业务类型，UE需发送的数据的业务类型是5，基站配置的功率信息中与业务类型5对应的发射功率为-120dBm，则UE确定-120dBm即为UE发送数据时的发射功率。
再一种可替换的方式为功率配置信息包括UE的发射功率与UE发送数据的优先级的对应关系。UE发送数据的优先级高时配置的UE的发射功率高，UE发送数据的优先级低时配置的UE的发射功率低；举例来说，若用不同的数字表示数据的优先级，UE需发送的数据的优先级是5，基站配置的功率信息中与优先级5对应的发射功率为-120dBm，则UE确定-120dBm即为UE发送数据时的发射功率。
803、基站向UE发送资源配置信息，该资源用于UE基于竞争的上行数据发送。
资源配置信息包括基站分配的公共的上行资源，该上行资源可以包括时域信息和频域信息，上行资源可以有多个，基站所覆盖的多个UE可以通过在公共的上行资源中选取上行资源进行上行数据发送。
当功率配置信息包括基站的期望接收功率与UE的业务类型或待发送数据的优先级的对应关系时，资源配置信息可以包括时频资源配置参数。
在一种可能的情况中，若功率配置信息包括UE的发射功率与UE发送数据的优先级的对应关系，假设终端1发送的数据的优先级高，则发射功率高，终端2发送的数据的优先级低，则发射功率低，但是由于终端1与终端2的无线环境不同，产生的路损也不同，可能会使得终端1和终端2到达基站时的接收功率相同，此时在资源冲突的情况下，基站不能成功接收终端1和终端2发送的任一部分数据。因此，可以为不同无线环境下的UE配置不同的时频资源，此时避免了这种发射功率不同的数据在资源冲突的情况下都无法被基站成功接收的情况。
示例性的，当功率配置信息包括UE发射功率与UE的业务类型的对应关系或UE发射功率与发送数据的优先级的对应关系时，基站所发送的资源配置信息可以包括UE测量基站的参考信号接收功率RSRP范围和时频资源配置参数或参考信号接收质量RSRQ范围和时频资源配置参数，时频资源配置参数包括物理资源块(Physical Resource Block，PRB)参数和子帧(Subframe,sf)参数，或时频资源配置参数包括PRB参数和系统帧参数。
举例来说，基站可以为不同的RSRP配置不同上行资源，以供UE根据接收到的参考信号的RSRP选择对应的资源发送上行数据。详细配置可以如表2：
表2
序号 资源配置 UE的RSRP
1 资源1 -120dBm±5dBm
2 资源2 -110dBm±5dBm
3 资源3 -100dBm±5dBm
…… …… ……
具体的资源配置可以如表3所示，其中纵向表示频率，用物理资源块PRB表示，横向表示时间，用子帧sf表示。
表3
Figure PCTCN2016100949-appb-000001
资源配置参数可以是PRB开始的资源标识、PRB结束的资源标识和子帧参数，例如子帧参数可以是10个比特位(bitmap)，1表示该子帧资源有效，则上述资源1、资源2和资源3对应的时频资源 配置参数如表4所示：
表4
资源 PRB开始 PRB结束 子帧参数
1 3 5 1001001000
2 1 4 0100010000
3 2 6 0010100010
可选的，也可以是子帧采用子帧开始/子帧结束的方式来表示，PRB使用bitmap的方式来表示。
804、当UE生成上行数据时，UE确定待发送的数据的优先级，再根据基站的期望接收功率与UE发送数据的优先级的对应关系确定将数据发送至基站的期望接收功率，进而根据将数据发送至基站的期望接收功率和路损值确定UE发送数据时的发射功率。
当UE的上行数据生成时，UE对该数据的业务类型或优先级进行判断，然后根据基站下发的功率配置信息确定基站的期望接收功率。举例来说，当基站下发的功率配置信息如表1时，UE判断所需发送数据的优先级为5，根据表1得出基站的期望接收功率为-120dBm，UE再根据基站广播的参考信号的发射功率与UE测量的参考信号的接收功率获取路损值，将基站的期望接收功率与路损值相加，即得到UE发送数据时的发射功率。
805、UE根据确定的发送数据时的发射功率在确定的上行资源上发送上行数据。
UE可以在基站分配的多个上行资源中确定适当的上行资源用于发送上行数据。
806、UE确定是否接收到基站发送的ACK，若是，则确定基站成功接收数据；若否，则执行步骤807。
基站在步骤805分配的上行资源上监听是否有上行数据，如果接收到UE发送的上行数据并能成功解码出来，则向该UE反馈确认信息(Acknowledgement，ACK)，即认为基站成功接收数据。若UE 没有接收到基站的反馈信息，则UE认为基站没有成功接收到数据。
应用上述802-806步骤的说明，如图9所示，当UE1和UE2在基站的覆盖范围内，UE1和UE2接收基站发送的功率配置信息和公共的上行资源的配置信息，可根据功率配置信息中UE1和UE2数据的优先级与基站的期望接收功率确定UE1和UE2分别对应的发射功率，假设UE1数据的优先级高于UE2数据的优先级，则UE1对应的基站的期望接收功率高于UE2对应的基站的期望接收功率，当UE1和UE2基于竞争资源向基站发送上行数据时，基站在相同的上行资源上能够成功接收UE1发送的数据，那么基站向UE1反馈ACK，UE2在未接收到ACK时，确定基站未接收到UE2发送的数据，则UE2确定向基站重发数据，UE2继续执行步骤807，这样一来，多个UE基于竞争资源向基站发送上行数据时，可保证部分UE发送成功，减少了重传数据的UE的数量，从而从整体上降低了数据发送的时延。
807、UE确定重传数据时的发射功率，重传数据时的发射功率为前一次发送数据时的发射功率与预设的幅度值之和。
重传数据时的发射功率为前一次发送数据时的发射功率与预设的幅度值之和，这样一来，提高重传数据时的发射功率，也就增加了重传数据的成功率，可以降低重传数据的次数。
步骤802中的表1还可以包括预设的幅度值，具体地，基站可以配置如表5形式的功率配置列表。
表5
序号 数据的优先级 基站的期望接收功率 预设的幅度值
1 3 -110dBm 10dBm
2 0 -100dBm 10dBm
3 5 -120dBm 10dBm
…… …… …… ……
预设的幅度值可以是相同的，如表5所示，预设的幅度值都为10dBm，也可以是按照数据的优先级的不同设置不同的预设的幅度值。例如UE发送的数据的优先级为3，初传数据时基站的期望接收功率为-110dBm，重传数据时基站的期望接收功率为-100dBm，再根据路损值确定重传数据的发射功率即可。
808、UE使用基站分配的上行资源重传数据。
这样一来，为不同的业务类型或不同优先级对应的数据设置了不同的基站期望接收功率，以便根据确定的期望接收功率获取终端发送数据时的发射功率，保证业务类型的重要程度高或数据的优先级高的上行数据具有较高的基站期望接收功率，业务类型的重要程度低或数据的优先级低的上行数据具有较低的基站期望接收功率，这样在多个UE基于竞争资源的数据发送所发生的资源冲突的情况下可以保证期望接收功率高的数据发送成功，基站接收到高功率的数据，减少重传数据的UE数量，从而从整体上减少数据发送的时延。
下面对UE发送上行数据，功率配置信息包括基站的期望接收功率与UE对基站的无线环境测量信息的对应关系的情况进行说明。
本发明实施例提供一种数据发送方法，如图10所示，包括：
1001、基站接收并统计基站覆盖范围内的UE发送的UE对无线环境的测量信息，测量信息包括参考信号接收功率RSRP或参考信号接收质量RSRQ。
也就是说，本实施例中，UE所处无线环境可以用参考信号的接收功率RSRP或参考信号的接收质量RSRQ来表征。
1002、基站向UE发送功率配置信息，功率配置信息包括基站的期望接收功率与UE对无线环境的测量信息的对应关系，功率配置信息用于使UE获取发送数据时的发射功率。
基站可以以列表的形式配置该功率配置信息，如表6所示：
表6
序号 UE测量基站的RSRP或RSRQ 基站的期望接收功率
1 -90dBm -100dBm
2 -100dBm -110dBm
3 -110dBm -120dBm
…… …… ……
其中，UE测量基站的RSRP或RSRQ越大，基站的期望接收功率越大，这是因为如果UE测量基站的RSRP或RSRQ越大，那么UE所处的无线环境的信号质量越好，UE的上行数据越容易发送成功，因此基站的期望接收功率越大时，也就更加保证UE的上行数据更容易发送成功。反之，UE测量基站的RSRP或RSRQ越小，那么UE所处的无线环境的信号质量越差，UE的上行数据越难以发送成功，因此基站的期望接收功率越小，也就使得该UE在基于竞争资源的数据发送时保证发射功率较高的UE的数据发送成功，即在基于竞争资源的数据发送时对不同的无线环境中期望接收功率较高的UE的干扰越小，可以保证不同的无线环境中期望接收功率较高的UE的数据发送成功。
一种可替换的方式是功率配置信息包括UE的发射功率与UE对基站的无线环境测量信息的对应关系，可以是UE测量基站的无线环境越好，即UE测量基站的RSRP或RSRQ越大，UE的发射功率越大，尽可能的保证部分发送发射功率高的数据发送成功。
1003、基站向UE发送上行资源的配置信息，该上行资源用于UE基于竞争的上行数据发送。
上行资源的配置信息可以参考步骤803。
1004、UE测量基站的RSRP或RSRQ，根据RSRP或RSRQ与基站的期望接收功率的对应关系确定将数据发送至基站的期望接收功率，进而UE根据将数据发送至基站的期望接收功率和路损值确 定UE发送数据时的发射功率。
当UE的上行数据生成时，UE测量基站的RSRP或RSRQ，然后根据基站下发的功率配置信息确定基站的期望接收功率。举例来说，当基站下发的功率配置信息如表6时，UE测量得到的基站的RSRP为-90dBm，根据表6得出基站的期望接收功率为-100dBm。UE再根据基站广播的参考信号的发射功率和UE测量的参考信号的接收功率获取路损值，将基站的期望接收功率与路损值相加，即得到UE发送数据时的发射功率。
1005、UE使用基站分配的上行资源发送上行数据。
UE可以在基站分配的多个上行资源中确定适当的上行资源用于发送上行数据。
1006、UE确认是否接收到基站发送的ACK，若是，则确定基站成功接收数据；若否，则执行步骤1007。
基站在步骤1005分配的上行资源上监听是否有上行数据，如果接收到UE发送的上行数据并能成功解码出来，则向该UE反馈确认信息即认为基站成功接收数据。若UE没有接收到基站的反馈信息，则UE认为基站没有成功接收到数据。
应用上述1002-1006步骤的说明，如图11所示，当UE1和UE2在基站的覆盖范围内，UE1和UE2接收基站发送的功率配置信息和公共的上行资源的配置信息，可根据功率配置信息中UE1和UE2的无线环境与基站的期望接收功率确定UE1和UE2分别对应的发射功率，假设UE1的RSRP或RSRQ高于UE2的RSRP或RSRQ，那么UE1对应的基站的期望接收功率高于UE2对应的基站的期望接收功率，当UE1和UE2基于竞争资源向基站发送上行数据时，由于基站接收UE1发送数据时的功率高于基站接收UE2发送数据时的功率，如果UE1和UE2发生资源冲突，基站在相同的上行资源中能够成功接收UE1发送的数据，那么基站向UE1反馈ACK，UE2在未接收到ACK时，确定基站未接收到UE2发送的数据，则UE2确定向基 站重发数据，UE2继续执行步骤1007。
1007、UE确定重传数据时的发射功率，重传数据时的发射功率为前一次发送数据时的发射功率与预设的幅度值之和。
具体地，步骤1002中的表3也可以配置如表7形式的功率配置列表。
表7
序号 UE测量基站的RSRP 基站的期望接收功率 预设的幅度值
1 -90dBm -100dBm 10dBm
2 -100dBm -110dBm 10dBm
3 -110dBm -120dBm 10dBm
…… …… …… ……
预设的幅度值可以是相同的，如表7所示，预设的幅度值都为10dBm，也可以是按照RSRP的不同值设置不同的预设的幅度值。例如UE测量基站发送的参考信息的RSRP为-100dB，初传数据时基站的期望接收功率为-110dBm，重传数据时基站的期望接收功率为-100dBm，再根据路损值确定重传数据时的发射功率即可。
1008、UE使用基站分配的上行资源重传数据。
这样一来，为不同的无线环境对应的数据设置了不同的基站期望接收功率或终端发射功率，RSRP值越大或RSRQ越大，基站的期望接收功率越大，这样在多个UE基于竞争资源的数据发送所发生的资源冲突的情况下保证一部分接收功率较高的数据发送成功，减少重传数据的UE数量，从而从整体上减少数据发送的时延。
下面对UE之间发送数据，且基站根据不同业务类型或不同数据的优先级来配置UE的发射功率的情况进行说明。
本发明实施例提供一种数据发送方法，如图12所示，包括：
1201、基站接收并统计基站覆盖范围内的UE发送的数据业务类型或数据优先级；或基站接收核心网发送的不同的业务对应的 QoS，进而根据QoS信息确定业务类型或数据的优先级。
UE具体何时向基站发送业务类型或数据的优先级以及基站如何根据核心网发送的QoS信息来确定数据的业务类型或数据的优先级可以参考上述步骤801。
1202、UE向基站发送自身发射功率。
UE的发射功率值可以是UE根据自身的接收能力和解码能力确定的。
1203、基站向UE发送功率配置信息，功率配置信息包括UE的发射功率与UE发送数据的业务类型或数据的优先级的对应关系，功率配置信息用于使UE获取发送数据时的发射功率。
在图8所示的实施例中，基站是将自身的期望接收功率与UE发送数据的业务类型或数据的优先级来对应的，在本实施例中，基站是将UE自身的发射功率与UE发送数据的业务类型或数据的优先级来对应的。例如基站在确定UE的最大接收功率和最小接收功率后，根据相同或不同的间隔将最大接收功率与最小接收功率之间的功率范围划分为不同功率等级，不同的功率等级对应不同的业务类型或不同的数据的优先级。
具体地，基站可以配置如表8形式的功率配置列表，优先级“0”表示最高优先级。
表8
序号 数据的优先级 UE发射功率
1 3 -110dBm
2 0 -100dBm
3 5 -120dBm
…… …… ……
举例来说，若功率配置列表如表8所示，UE需发送的数据的优先级是3，则UE发送数据时所用的发射功率为-110dBm。
一种可替换的方式为基站根据不同的对端的无线环境测量信息来配置UE的发射功率，可以是对端的无线环境测量信息更好，即UE测量到的对端发送的参考信号的RSRP或RSRQ越高，UE的发射功率越高，以便在资源冲突的情况下，对端尽可能地接收到发射功率高的数据。
1204、基站向其覆盖范围内的UE发送D2D通信链路(Sidelink,SL)上的通信资源的配置信息，该资源用于UE基于竞争的D2D通信数据的发送。
通信资源的配置信息可以是时域信息和频域信息，通信资源的配置信息可以有多个，基站所覆盖的多个UE可以通过这些通信资源的配置信息确定发送数据的资源以进行D2D通信。
在一种可能的情况中，当功率配置信息包括UE的发射功率与UE发送数据的业务类型或数据的优先级时，可能出现不同发射功率的发送端发送的数据到达接收端时的接收功率相同，导致不同的发送端在资源冲突的情况下，接收端无法成功接收发送端发送的数据，于是，与步骤803类似的，基站所发送的资源配置信息可以包括UE测得的参考信号接收功率RSRP范围和时频资源配置参数，或包括参考信号接收质量RSRQ范围和时频资源配置参数，时频资源配置参数包括物理资源块PRB参数和子帧参数，或时频资源配置参数包括PRB参数和系统帧参数。具体地，可以参考步骤803。
举例来说，若功率配置信息包括UE的发射功率与UE发送的数据的优先级的对应关系，终端1发送的数据的优先级高，则发射功率高，终端2发送的数据的优先级低，则发射功率低，但是由于终端1与终端2的无线环境不同，产生的路损也不同，可能会使得终端1和终端2到达对端时的接收功率相同，此时在资源冲突的情况下，对端不能成功接收任何一部分数据。因此，可以为不同无线环境下的UE配置不同的时频资源，此时避免了这种发射功率不同的数据在资源冲突的情况下都无法被对端成功接收的情况。
1205、UE确定待发送的数据的业务类型或数据的优先级，再根据UE的发射功率与UE发送的数据的业务类型或数据的优先级的对应关系确定将数据发送至对端UE的发送功率。
当UE的上行数据生成时，UE对该数据的业务类型或优先级进行判断，然后根据基站下发的功率配置信息确定UE的发射功率。举例来说，当基站下发的功率配置信息如表8时，UE判断所需发送数据的优先级为3，根据表8得出UE的发射功率为-110dBm。即表示UE在发送优先级为3的数据时所用的发射功率为-110dBm。
1206、UE使用基站分配的通信资源进行D2D通信。
UE通过基站分配的通信资源的配置信息选取适当的资源与向对端UE发送数据。
1207、UE确认是否接收到对端UE反馈的ACK，若是，则认为对端UE成功接收数据；若否，则执行步骤1208。
这里的对端UE是指与UE进行D2D通信的另一个UE。多个UE给同一个UE发送数据时，对端UE在基站分配的资源上监听是否有D2D数据，如果接收到发送数据的UE发送的D2D数据并能成功解码出来，则向该发送数据的UE反馈ACK信息，ACK表示接收成功。若发送数据的UE没有接收到对端UE的ACK信息，则发送数据的UE认为对端UE没有成功接收到数据。
举例来说，如图13所示，假设UE2和UE3基于竞争资源向UE1发送D2D数据，UE1在基站分配的资源上监听是否有D2D数据，如果UE1接收到UE2发送的D2D数据并能成功解码出来，则UE1向该UE2反馈ACK信息，UE2认为UE1成功接收到数据。若UE3没有接收到UE1的ACK信息，则UE3认为UE1没有成功接收到数据。
1208、UE确定重传数据时的发射功率，重传数据时的发射功率为前一次发送数据时的发射功率与预设的幅度值之和。
步骤1203中的表8还可以包括预设的幅度值，具体地，基站可以配置如表9形式的功率配置列表。
表9
序号 数据的优先级 UE发射功率 预设的幅度值
1 3 -110dBm 10dBm
2 0 -100dBm 10dBm
3 5 -120dBm 10dBm
…… …… …… ……
预设的幅度值具体如何设置可以参考上述步骤807。
1209、UE使用基站分配的资源重传数据。
本发明实施例中，UE进行D2D通信时根据数据的业务类型或数据的优先级为需发送的数据设置不同的发射功率，或根据不同的无线环境为需发送的数据设置不同的发射功率，这样在发生资源冲突的情况下，对端可以成功接收到发射功率较高的数据，进而减少重传数据的UE数量，从而从整体上减少数据发送的时延。
