附图说明
附图是用来提供对本公开的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本公开，但并不构成对本公开的限制。在附图中：
图1是根据一实施例示出的一种分配传输功率的方法的流程示意图；
图2是根据一实施例示出的一种分配传输功率的装置的结构示意图；
图3是根据一实施例示出的另一种分配传输功率的装置的结构示意图；
图4是根据一实施例示出的又一种分配传输功率的装置的结构示意图。
具体实施方式
以下结合附图对本公开的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开，并不用于限制本公开。
首先对本公开的应用场景进行说明，本公开提供的分配传输功率的方法、装置以及终端可以应用于车联网中，车联网是由车辆位置、速度和路线等信息构成的巨大交互网络。通过GPS(Global Positioning System，全球定位系统)、RFID(Radio Frequency Identification，无线射频识别)、传感器、摄像头图像处理等装置，车辆可以完成自身环境和状态信息的采集；通过互联网技术，所有的车辆可以将自身的各种信息传输汇聚到中央处理器；通过计算机技术，这些大量车辆的信息可以被分析和处理，计算出不同车辆的最佳路线，从而汇报路况和安排信号灯周期。
现在，车联网从发展轨迹上可以分为以下三个阶段：
第一阶段：车载信息服务(路线规划、导航、远程诊断、多媒体下载)。
第二阶段：辅助驾驶(限速提醒、碰撞预警；车速引导、道路紧急信息、驾驶行为提示灯)。
第三阶段：自动驾驶及智能交通(结合环境感知和云端智能控制协作式自动驾驶和智能交通)。
目前，3GPP(3rd Generation Partnership Project，第三代合作伙伴计划)中正在进行LTE-V(车联网专用通信)的标准化研究工作(主要针对第二阶段的需求)，包括V2V(车与车通信)、V2X(车与基础设施通信、车与基站通信、车与人的通信需求)的研究。未来的5G网络将具备超大带宽传输、超低时延处理、精确位置感知能力，将全面支持车联网发展的第三阶段的需求。
在第二阶段和第三阶段中，通过云端智能控制和处理来提供辅助驾驶或自动驾驶是目前业界在车联网领域的重点研究方向，要实现云端智能控制和处理需要在车与云端智能服务器间具有可靠的传输链路，可以通过LTE-V(车联网协议)技术中的V2X来实现，包括车与基站通信，以及车与基础设施通信。
目前正在研究制定的车联网的频谱分配，极有可能在与国际接轨的5.9GHz频段上为车联网分配专用频率，V2V通信、V2X通信将使用5.9GHz频段的相邻载波，在进行多条链路并发工作时，上述三条通信链路可能采用同一功放去推动，而受限于终端功放的能力，将仍然保持与目前单条链路工作时相同的总功率限制(如23dBm)。而V2V和V2I(车与基站通信)链路都是按照最高发射功率进行发射。因此，在需求的传输功率高于总功率限值的情况下，当V2V链路通信时，V2X链路可能无法工作；或者，当V2X链路通信时，V2V链路可能无法工作，从而无法实现多条通信链路并发工作。
为了实现多条通信链路并发工作，确保高优先级通信链路的数据正常传输，本公开提供一种分配传输功率的方法、装置以及终端，能够通过获取当前具有通信需求的通信链路的业务优先级，并根据该业务优先级为通信链路 分配传输带宽，从而灵活调配有限的传输功率，以保证车联网中高优先级通信链路的数据传输，解决了现有多条通信链路无法并发工作的技术问题。
下面结合具体的实施例对本公开进行详细说明。
图1为本公开实施例提供的一种分配传输功率的方法，如图1所示，应用于终端，在本实施例中，该终端可以设置在车辆上，该方法包括：
S101、确定当前时刻具有通信需求的通信链路。
其中，该当前时刻具有通信需求的通信链路即为在当前时刻有传输数据的需求的通信链路；或者，在当前时刻将传输数据的通信链路。
在本公开实施例一种可能的实现方式中，终端可以接收通信对端发送的调度信息，并根据该调度信息确定当前时刻的通信链路是否是具有通信需求的通信链路。
例如，车与基站的通信是由基站控制的，基站向终端下发控制信息，该控制信息包括对上行数据传输的调度信息，终端接收基站发送的控制信息，即可根据该调度信息获知当前时刻车与基站进行数据传输的时刻等信息，从而确定车与基站之间的通信链路是具有通信需求的通信链路。
S102、获取每条通信链路对应的功率请求值，并将该每条通信链路对应的功率请求值相加得到累加功率值。
在本步骤中，在确定当前时刻具有通信需求的通信链路后，可以通过以下两种方式中的任一种获取每条通信链路对应的功率请求值：
方式一：在通信对端接收到上一时刻终端发送的第一数据包时，接收该通信对端根据该第一数据包发送的反馈信息，其中，该反馈信息包括该通信对端根据该第一数据包得到的功率调整值，终端根据该功率调整值得到该功率请求值。
在本方式中，通信对端在接收到该第一数据包后，对该第一数据包进行解调获得调整参数，该调整参数可以是误码率或者误块率，终端确定该调整 参数是否大于或者等于第一预设值，在确定得到的调整参数大于或者等于该第一预设值时，则表示需要提升传输功率，并进一步确定该调整参数与第一预设值的差值对应的预设量化区间，并获取对应的预设量化区间的功率调整值，并将该功率调整值发送至终端，终端将该功率调整值与该通信链路在上一时刻的传输功率相加得到该功率请求值。
通信对端在确定得到的调整参数小于该第一预设值时，还可以确定得到的调整参数是否小于或者等于第二预设值，在确定得到的调整参数小于或者等于第二预设值时，则表示需要降低传输功率，并进一步确定该调整参数与第一预设值的差值对应的预设量化区间，并获取对应的预设量化区间的功率调整值，并将该功率调整值发送至终端，终端将该功率调整值与该通信链路在上一时刻的传输功率相加得到该功率请求值。
例如，预设量化区间可以划分为5个，对应的功率调整值可以分别预置为：-2dB，-1dB，0dB，1dB，2dB，其中，-1dB表示将该通信链路在上一时刻的传输功率降低1dB，-2dB表示将上一时刻的传输功率降低2dB，0dB表示无需进行功率调整(即当前时刻的功率请求值与上一时刻的传输功率相同)，1dB表示将该通信链路在上一时刻的传输功率提高1dB，-2dB表示将上一时刻的传输功率提高2dB。这样，当调整参数与第一预设值的差值所属的预设量化空间对应的功率调整值为2dB时，则将上一时刻通信链路的传输功率提高2dB得到当前时刻的功率请求值，当调整参数与第一预设值的差值所属的预设量化空间对应的功率调整值为-2dB时，则将上一时刻通信链路的传输功率降低2dB得到当前时刻的功率请求值，以此类推，根据调整参数与第一预设值的差值所属的预设量化空间对应的功率调整值调整上一时刻的传输功率得到当前时刻的功率请求值。
需要说明的是，本公开并不局限于先判断该调整参数是否大于或者等于第一预设值，并在该调整参数小于该第一预设值时，再判断调整参数是否小 于或者等于第二预设值；也可以先判断调整参数是否小于或者等于第二预设值，在该调整参数大于该第二预设值，再判断该调整参数是否大于或者等于第一预设值，本实施例对具体的判断顺序不作限定，例如，还可以同时判断。
方式二：接收通信对端发送的第二数据包，根据该第二数据包得到调整参数，并根据该调整参数得到功率调整值，并根据该功率调整值得到该功率请求值。
同样地，该调整参数可以是误码率或者误块率，在本方式中，终端接收通信对端发送的第二数据包，并对该第二数据包进行解调得到该调整参数，并确定该调整参数是否大于或者等于第一预设值，在确定得到的调整参数大于或者等于该第一预设值时，则表示需要提升传输功率，并进一步确定该调整参数与第一预设值的差值对应的预设量化区间，并获取对应的预设量化区间的功率调整值，将该功率调整值与该通信链路在上一时刻的传输功率相加得到该功率请求值。
在确定得到的调整参数小于该第一预设值时，还可以确定得到的调整参数是否小于或者等于第二预设值，在确定得到的调整参数小于或者等于第二预设值时，则表示需要降低传输功率，并进一步确定该调整参数与第一预设值的差值对应的预设量化区间，并获取对应的预设量化区间的功率调整值，将该功率调整值与该通信链路在上一时刻的传输功率相加得到当前时刻的功率请求值。
在方式二中，本公开并不局限于先判断该调整参数是否大于或者等于第一预设值，并在该调整参数小于该第一预设值时，再判断调整参数是否小于或者等于第二预设值；也可以先判断调整参数是否小于或者等于第二预设值，在该调整参数大于该第二预设值，再判断该调整参数是否大于或者等于第一预设值，本实施例对具体的判断顺序不作限定，例如，还可以同时判断。
由上可知，上述两种方式的区别在于，方式一是通信对端根据终端在上 一时刻发送的第一数据包得到调整参数，并根据该调整参数得到功率调整值，并将该功率调整值发送至终端，终端根据该功率调整值得到功率请求值；而方式二则是终端根据通信对端发送的第二数据包得到调整参数，并根据该调整参数得到功率调整值，进而根据该功率调整值得到功率请求值，可见，方式一是通信对端得到功率调整值后，发送至终端，终端根据功率调整值得到功率请求值，而方式二则是由终端自行根据与通信对端通信的第二数据包得到功率请求值的。
需要说明的是，在该调整参数小于该第一预设值且大于第二预设值时，则确定不需要进行功率调整。
这样，在得到每条通信链路的功率请求值后，将得到的功率请求值相加得到累加功率值。
由于不同国家对不同的通信业务有不同的管理要求，例如，对车与车通信的最大发射功率在中国可能是20dBm，在美国可能是23dBm，即使有功率余量也不能超过这些地区的管理要求，从而导致即使通信链路的功率请求值超过了最大发射功率，也仍然按照最大发射功率进行数据传输，从而无法满足通信链路的传输需求，为了解决上述问题，在本公开另一实施例中，在进行步骤S103之前，可以进一步确定该通信链路的功率请求值是否大于或者等于该通信链路的最高发射功率，并在确定该通信链路的功率请求值大于或者等于该通信链路的最高发射功率时，将该功率请求值设置为该最高发射功率，并在将该功率请求值设置为该最高发射功率后，执行后续步骤S103，这样，可以根据不同终端类型及网络覆盖情况，在不同通信链路中去配置不同的最大发射功率，如在高速公路场景下，若基站的覆盖非常好(车与基站间通信对功率需求不敏感)的条件下，可以将更多的功率配置给车与车通信，反之，在基础网络覆盖特别差，非封闭道路上，对车与车通信的需求可能不是刚需时，可以将车与基站间通信的最大发射功率设置的更高，也 就意味着将更多功率配置给车与基站间的通信，从而满足不同网络覆盖场景下，不同通信链路对发射功率敏感度的需求。
另外，在确定该通信链路的功率请求值小于该通信链路的最高发射功率时，直接执行步骤S103。
S103、在确定该累加功率值大于或者等于预设功率限制值时，获取该每条通信链路的业务优先级，并根据该业务优先级为该每条通信链路进行传输功率的分配。
其中，在确定该累加功率值小于该预设功率限制值时，则确定当前终端待分配的传输功率能够满足全部通信链路的传输，因此，可以将该功率请求值设置为对应通信链路的传输功率。
而在本步骤中，每条通信链路对应设置有业务优先级，具体可以通过预先设置对应的业务优先级标识标示业务优先级的顺序，以反映通信链路对应的业务的重要性，例如，业务优先级可以配置如下：车与车通信安全相关业务的优先级大于车与云端机器人交互安全驾驶相关业务，车与云端机器人交互安全驾驶相关业务的优先级大于车与通信基础设施管理相关通信业务，车与通信基础设施管理相关通信业务的优先级大于车与云端机器人交通辅助业务，其中，车与车通信安全相关业务可以包括：安全提醒、自动驾驶传导信息、高速传感器信息交互信息等业务，车与云端机器人交互安全驾驶相关业务可以包括：云端辅助驾驶、云端车辆引导、云端交通信号提醒、云端路况提醒等业务，车与通信基础设施管理相关通信业务可以包括：缴费信息、交通信号提醒、交通信息采集、路况提醒等业务，车与云端机器人交通辅助业务可以包括：实时三维地图下载推送、车载娱乐通信、车辆远程监测、车辆在线导航等业务。
在本实施例中，可以根据具体的业务设置不同的优先级，例如，车与车通信安全相关业务设置的业务优先级标识为1，车与云端机器人交互安全驾 驶相关业务设置的业务优先级标识为2，车与通信基础设施管理相关通信业务设置的业务优先级标识为3，车与云端机器人交通辅助业务的业务优先级标识为4，业务优先级标识从1至4依次表示业务优先级由高至低。
需要说明的是，上述关于业务优先级标识的相关示例性描述只是举例说明，本公开不作限定。
这样，终端通过通信链路对应的业务优先级标识即可获知该通信链路的业务优先级。
在本步骤中，在得到通信链路的业务优先级后，可以通过以下四种方式中的任一种为每条通信链路进行传输功率的分配：
方式一：暂停该业务优先级最低的通信链路在该当前时刻的数据传输。
这样，通过暂停该业务优先级最低的通信链路在当前时刻的数据传输，从而优先保证高优先级的通信链路的传输功率，确保高优先级业务的数据传输。
另外，由于业务优先级最低的通信链路可能有多条，因此，在本公开另一实施例中，在确定该业务优先级最低的通信链路有多条时，获取该通信链路的传输时延需求信息，并根据该传输时延需求信息暂停传输时延需求最低的通信链路的数据传输。
在本方式中，该通信链路上待传输的数据中具有业务QoS(Quality of Service，服务质量)标识或业务类型标识等信息，这些信息中包括传输时延需求信息，也即业务最高可允许的传输时延值或反映该值的标识信息。
业务最高可允许的传输时延值越小，则表示业务对传输时延需求越高，需要优先保证传输，因此，在本实施例中，优先保证传输业务最高可允许传输时延值最小的通信链路的数据传输，暂停业务最高可允许的传输时延值最大的通信链路的数据传输。
在业务优先级最低的通信链路的数据传输暂停后，在本公开另一实施例 中，可以在下一时刻继续确定通信链路的累加功率值是否大于或者等于预设功率限制值，若累加功率值仍然大于或者等于预设功率限制值则继续暂停该业务优先级最低的通信链路的数据传输，若累加功率值小于该预设功率限制值则恢复该业务优先级最低的通信链路的数据传输。
方式二：按照该业务优先级的顺序，依次为该通信链路分配传输功率。
在本方式中，可以按照业务优先级的顺序，优先满足最高业务优先级的通信链路的功率请求值，其次满足次高优先级的通信链路的功率请求值，以此类推，直至全部待分配的传输功率都被分配完成。
例如，当前具有通信需求的4条通信链路对应的业务分别为：车与车通信安全相关业务、车与云端机器人交互安全驾驶相关业务、车与通信基础设施管理相关通信业务以及车与云端机器人交通辅助业务，其中，车与车通信安全相关业务设置的业务优先级标识为1，车与云端机器人交互安全驾驶相关业务设置的业务优先级标识为2，车与通信基础设施管理相关通信业务设置的业务优先级标识为3，车与云端机器人交通辅助业务的业务优先级标识为4，业务优先级标识从1至4依次表示业务优先级由高至低。在进行传输功率的分配时，将待分配的传输功率(与预设功率限制值相同)优先为车与车通信安全相关业务的通信链路分配传输功率，以满足该通信链路功率请求值，此时，剩余的待分配的传输功率为预设功率限制值中除去为车与车通信安全相关业务的通信链路分配的传输功率后的功率，然后将该剩余的待分配功率为车与云端机器人交互安全驾驶相关业务的通信链路分配传输功率，以满足该通信链路功率请求值，以此类推，直至全部待分配的传输功率都分配完。
另外，若待分配的传输功率分配完成后，低优先级的通信链路可能没有分配到传输功率，则未分配到传输功率的低优先级的通信链路无法进行数据传输，从而优先确保高优先级的数据传输。
方式三：获取与该每条通信链路的业务优先级对应的预设权值，并按照该预设权值为该每条通信链路分配传输功率。
在本方式中，可根据通信链路的业务优先级预先对不同业务的通信链路设置对应的权值，从而在分配传输功率时，按照预设权值进行分配。
例如，权值1对应的通信链路的业务优先级最高，权值2对应的通信链路的业务优先级第2，权值3对应的通信链路的业务优先级第3，若权值1对应的通信链路的预设权值为70％，则表示终端将待分配的传输功率的70％分配至权值1对应的通信链路，此时，终端可以将待分配的传输功率的70％(相当于预设权值)用于保障权值1对应的通信链路的数据传输，若待分配的传输功率的70％大于或者等于权值1对应的通信链路的功率请求值，则以该功率请求值传输数据，若待分配的传输功率的70％小于权值1对应的通信链路的功率请求值，则以待分配的传输功率的70％进行该权值1对应的通信链路的传输。
若权值2对应的通信链路的预设权值为70％，则表示终端将待分配的传输功率中，去除权值1的通信链路的传输功率后的剩余功率的70％分配至权值2对应的通信链路；在待分配的传输功率的70％大于或者等于权值1对应的通信链路的功率请求值时，去除权值1的通信链路的传输功率后的剩余功率的70％用于保障权值2对应的通信链路的数据传输，若剩余功率的70％大于或者等于权值2对应的通信链路的功率请求值，则以权值2对应的通信链路的功率请求值进行传输，否则以剩余功率的70％进行权值2对应的通信链路的传输，以此类推，直至按照预设权值完成传输功率的分配。
需要说明的是，上述关于预设权值的相关描述只是举例说明，本公开不作限定。
方式四：将该业务优先级最低的通信链路的传输带宽降低至预定带宽。
其中，该预定带宽可以是功率谱密度满足覆盖要求的带宽。
在本方式中，考虑到车与基站的通信需要复杂的交互信息才能降低传输带宽，而且降低传输带宽还可能影响其他用户的性能，因此，在本公开另一实施例中，在获知通信链路的业务优先级后，可以进一步确定业务优先级最低的通信链路是否是V2V(车与车通信)链路或者V2I(车与基础设施通信)链路，在确定业务优先级最低的通信链路是V2V链路或者V2I链路时，降低该通信链路的传输带宽。
当然，在业务优先级最低的通信链路有多条时，仍然可以通过传输时延需求信息确定需要降低传输带宽的通信链路，在本实施例中，可以降低业务最高可允许的传输时延值最大的通信链路的传输带宽，具体可以参考方式一中关于传输时延需求信息的描述，此处不再赘述。
需要说明的是，在确定业务优先级最低的通信链路是V2V链路或者V2I链路时，仍然可以按照上述方式一至方式三中的任一种进行传输功率的分配。
采用上述方法，通过获取当前具有通信需求的通信链路的业务优先级，并根据该业务优先级为通信链路分配传输带宽，从而灵活调配有限的传输功率，以保证车联网中高优先级通信链路的数据传输，解决了现有多条通信链路无法并发工作的技术问题。
