附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例中所需要使用的附图作简单地介绍，显而易见地，下面所描述的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

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的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。
图1是本发明实施例的一个V2V通信的场景的示意图。图1示出的为在车道上的4个车相互之间进行通信的示意图。
V2V通信可通过多个车载单元(On board Unit，OBU)之间的无线通信，实现辅助驾驶和自动驾驶，从而能够有效地提升交通的通行效率，避免交通事故，降低行车风险。
图2和图3分别是本发明实施例的应用场景的示意图。在图2和图3中，UE 20能够与基站10进行直接通信，UE 20可以称为中继(relay)UE。UE30不一定能够与基站10进行直接通信，但是UE 30能够与UE 20进行通信，进而UE 30能够通过UE 20实现与基站10之间的通信，UE 30可以称为远端(remote)UE。
图2中，UE 20与能够与之通信的UE 30之间的通信距离较小，例如10米(m)左右。图3中，UE 20与能够与之通信的UE 30之间的通信距离较大，例如100m到1000m左右。
针对图2和图3的示意性场景，图4是本发明实施例的一个实际的应用场景的示意图。图4中的演进型基站(evolved NodeB，eNB)相当于图2和图3中的基站10。图4中的路边单元(Road Side Unit，RSU)和UE1、UE2和UE3可以是图2和图3中的UE 20和UE 30，例如，RSU为UE 20，能够与eNB进行直接通信；UE1、UE2和UE3为UE 30，能够通过RSU与eNB进行通信。另外，图4中还示出了全球导航卫星系统(Global Navigation Satellite System，GNSS)，可以用于为其他的网元提供定位等信息。
其中，RSU在功能上既可以是一个车载设备的功能，也可以是一个eNB的功能。其中，UE1、UE2和UE3可以指车载设备，车载设备之间可以通过边链路(Sidelink)进行V2V通信。车载设备随着车辆高速移动，例如，UE1和UE2之间相对运功时，具有最大的相对移动速度。
图4中所示的各个设备之间在进行通信时可以使用蜂窝链路的频谱，也可以使用5.9GHz附近的智能交通频谱。各个设备之间相互通信的技术可以基于LTE协议进行增强，也可以基于D2D技术进行增强。
本发明实施例中，边链路可以是指UE与UE之间的通信链路，在D2D通信中也称为D2D链路，另外某些场景也称为PC5链路。在车联网中，也可以称为V2V链路，或者车辆-设施(Vehicle to Infrastructure，V2I)链路，或者车辆-行人(Vehicle to Pedestrian，V2P)链路等。该边链路可以通过广 播、单播、多播或组播中的任意一种形式发送信息。其中，该边链路可以使用蜂窝链路的频谱，例如使用蜂窝链路的上行频谱。
本发明实施例中，UE也可以称为终端，可以包括车辆上的OBU，也可以包括路边的RSU等，还可以包括行人所使用的手机等。
V2V通信建议将控制信息(例如SA)和数据(Data)放在同一个子帧中，如图5所示。图5中(a)，SA和Data在同一个子帧的非相邻频域；图5中(b)，SA和Data在同一个子帧的相邻频域。也就是说，SA和data在频域的位置可以是相邻的或不相邻的。另外，SA可以承载于独立的物理信道中，如物理边链路控制信道(Physical Sidelink Control Channel，PSCCH)。或者，SA也可以与数据承载于同一个物理信道中，如物理边链路共享信道(Physical Sidelink Shared Channel，PSSCH)。
其中，在Rel-12的D2D协议中，也将SA所在的信道称为PSCCH信道，是用于传输UE之间控制信息的信道。该控制信息用来向接收机指示传输data部分的时频资源的位置、资源大小、调制和编码方案(Modulation and Coding Scheme，MCS)值等参数信息。在Rel-12的D2D中，SA与data分别位于不同的子帧中，因此它们的发送功率可以在各个子帧中独立地进行配置。
应注意，虽然在当前的LTE系统中，一个子帧所占用的时长一般为1毫秒(ms)，然而本发明实施例中，对一个子帧的时长不作限定。具体地，本发明实施例中，一个子帧的时长可以为一次传输占用最基本的时长，一个子帧的时长可以是预定义的长度。举例来说，可以是1ms；也可以是大于1ms，如2ms，10ms；还可以是小于1ms的时间，如0.625ms，0.125ms，0.2ms等。
由于SA和data的并行传输是基于多载波系统的，因此在一个子帧中，对于一个发射机而言，总的可用的发射功率是固定的，如不超过UE的最大发射功率。对于SA和data位于一个子帧的场景，当基站指示用户设备(User Equipment，UE)使用最大发射功率时，如果SA使用最大发射功率则data上就没有可用的发射功率，反之亦然。
本发明实施例所要解决的是，UE需要同时为SA和data在同一个子帧上传输时，如何确定数据信道和控制信道的发射功率。尤其是，当UE最大发射功率时，如何分别确定在控制信息和数据上的发射功率。
第一链路：表示UE之间的通信链路。可以是D2D链路或者V2X链路 或者边链路(Sidelink)等。举例来说，可以是前述图2或图3中UE 20与UE30之间的链路，可以是前述图4中RSU与UE3之间的链路。第一链路上的通信可以是基于单播、组播、广播中的任意一种方式进行。
第二链路：表示UE与基站之间的通信链路。可以是蜂窝链路。举例来说，可以是前述图2或图3中UE 20/UE 30与基站10之间的链路，可以是前述图4中RSU与eNB之间的链路。
中继UE：即relay UE，表示与基站能够直接通信的UE，并且能中转其它UE到基站的数据。举例来说，可以是前述图2或图3中的UE 20，可以是前述图4中的RSU。
远端UE：即remote UE，表示不一定能够与基站进行直接通信、但是可以通过中继UE与基站进行通信的UE。举例来说，可以是前述图2或图3中的UE 30，可以是前述图4中的UE1、UE2和UE3。
图6是本发明一个实施例的方法的示意性流程图。该方法的执行主体为UE，可以为上述中继UE，也可以为上述远端UE。如图6所示，该方法600包括：

其中，第一参数包括下列中的至少一种：数据信道的带宽，控制信道的带宽、第一链路所在载波的载波类型；
步骤630，UE在同一个子帧上发送控制信道与数据信道。
在步骤610中，第一链路的最大发射功率指的是该第一链路允许的发射功率的一个门限值，UE无论如何分配控制信道与数据信道的发射功率，则该控制信道的发射功率和数据信道的发射功率的总和都不应该超过第一链路允许的最大发射功率。

最大发射功率可以是预定义的，也可以是信令配置的，可以是小区公共的，也可以是用户特定的，本发明对此不做限定。
应注意，本发明实施例提到的发射功率的值可以用对数值(单位可以为dBm)也可以用线性值(单位可以为毫瓦mW，瓦W)来表示，即可以是单个频域传输资源(如一个PRB)上的值，也可以是整个传输带宽上的值。同样地，本发明后续的实施例所涉及到的功率，可以根据其单位确定其是对数值还是线性值。例如，
Figure PCTCN2016100945-appb-000003
是将最大发射功率用线性值表示，而PCMAX,c则是将最大发射功率用对数值表示。在本发明中，对其它表示功率的参数x，也分别使用
