所述第三资源在频域上所占用的资源块数量可以与所述子信道包含的资源块数量相同，所述第三资源位于所述第二资源在频域上占用的至少一个子信道中序号最小的子信道上。第一指示信息在指示第一资源时，同时指示了所述子信道包含的资源块数量，所以当事先预定义所述第三资源在频域上所占用的资源块数量与所述子信道包含的资源块数量相同时，所述第一通信设备的处理单元22可以直接获得所述第三资源在频域上所占用的资源块数量，当第一关系表如表1所示时，所述第一通信设备的处理单元22根据所述第三资源在频域上所占用的资源块数量和表1来确定所述第三资源在时域上所占用的符号数量，从而可以获得所述第一对应关系。例如当所述子信道包含的资源块数量为8时，所 述第一通信设备的处理单元22可以直接获得所述第三资源在频域上所占用的资源块数量也为8，当第一关系表如表1所示时,所述第一通信设备的处理单元22根据表1和所述第三资源在频域上所占用的资源块数量为8，可以确定所述第三资源在时域上所占用的符号数量为3，则所述第一对应关系为时域上所占用的符号数量为3和频域上所占用的资源块数量为8。
所述第一指示信息还可以包括所述第三资源在时域上所占用的符号数量和频域上所占用的资源块数量中的至少一个信息。当所述第一关系表如表1所示时，所述第一指示信息可以包含所述第三资源在频域上所占用的资源块数量，例如当所述第三资源在频域上所占用的资源块数量为6时，所述第一通信设备根据表1，可以确定所述第三资源在时域上所占用的符号数量为4，则所述第一对应关系为时域上所占用的符号数量为4和频域上所占用的资源块数量为6；当所述第一关系表如表2所示时，所述第一指示信息可以包含所述第三资源在时域上所占用的的符号数量，例如当所述第三资源在时域上所占用的的符号数量为7时，所述第一通信设备根据表2，可以确定所述第三资源在频域上所占用的资源块数量为3，则所述第一对应关系为时域上所占用的符号数量为7和频域上所占用的资源块数量为3；或者当所述第三资源在频域上所占用的资源块数量与所述子信道包含的资源块数量相同时，所述第一指示信息包含所述第三资源在时域上所占用的的符号数量，所述第一通信设备通过获得所述子信道包含的资源块数量从而可以获取所述第三资源在频域上所占用的资源块数量，例如当所述子信道包含的资源块数量为8时，所述第三资源在时域上所占用的符号数量为3时，则所述第一对应关系为时域上所占用的符号数量为3和频域上所占用的资源块数量为8；或者所述第一指示信息直接指示第一对应关系，所述第一指示信息可以包含所述第三资源在时域上所占用的符号数量和频域上所占用的资源块数量，所述第一通信设备可以直接获得所述第一对应关系，例如所述第一对应关系可以为时域上所占用的符号数量为4和频域上所占用的资源块数量为6。
步骤51，第一通信设备获取第三资源和第四资源，当第一通信设备和第二通信设备在网络覆盖范围外时，也就是在V2X的用户自选模式通信中，例如模式4中，第一通信设备获取第三资源和第四资源的具体步骤如图7所示。用户自选模式通信是基于通信设备自主选取传输控制信息和数据的资源的V2X通信，第一通信设备会在资源池中选取第三资源和第四资源，并通过侧行控制信息将第一通信设备选取的第三资源和第四资源告知其它的通信设备。
在步骤71中，所述第一通信设备的处理单元22在第五资源中选择第二资源，所述第二资源包括所述第三资源和所述第四资源，所述第五资源为预定义的用于侧行信息传输的资源集合，所述侧行信息包括所述侧行控制信息和所述侧行数据，所述第五资源包括时域上的至少一个时间单元和频域上的至少一个子信道，所述时间单元包括至少一个符号，所述子信道包括至少一个资源块，所述第五资源中用于传输侧行控制信息的资源的时域资源与频域资源所满足的预定义的第一对应关系，所述第三资源满足所述第一对应关系。所述第五资源可以为预定义的侧行通信资源池，所述第一通信设备在第五资源中自主选择第二资源；所述时间单元可以为时隙、微时隙或子帧；所述第一通信设备根据预定义的第一对应关系在第二资源中选择第三资源，根据所述第三资源的大小，在第二资源中确定第四资源。
如图8所示，以一个时隙为例，一个时隙可以包含14个符号，一个时隙中的最后一个符号用于保护间隔，实际用于传输控制信息和数据的符号数为13。图8只是给出了时隙内符号使用的一种示例，还可能有其他使用情况，例如第一个符号用于自动增益控制(Automatic Gain Control，AGC)，最后一个符号用于保护间隔，实际传输控制信息和数据的符号数为12。图8(a)给出了控制信息和数据资源映射的一种可能的示意图，即第三资源和第四资源的一种可能的配置情况。所述第一对应关系为时域上所占用的符号数量为3和频域上所占用的资源块数量为8，所述第二资源在时域上占用一个时隙和在频域上占用一个子信道，子信道的带宽为8个资源块，那么第三资源在时域上占用3个符号，在频域上占用8个资源块，第四资源在时域上占用10个符号，在频域上占用8个资源块；图8(b)给出了控制信息和数据资源映射的另一种可能的示意图，即第三资源和第四资源的一种可能的配置情况。所述第一对应关系为时域上所占用的符号数量为3和频域上所占用的资源块数量为8，所述第二资源在时域上占用一个时隙和在频域上占用两个子信道，子信道的带宽为8个资源块，那么第三资源在时域上占用3个符号，在频域上占用8个资源块，并且位于序号较小的子信道上，第四资源占用2个子信道，分别为在时域上占用10个符号，在频域上占用一个子信道，和在时域上占用13个符号，在频域上占用一个子信道。
所述第三资源可以包含m个控制信道单元，m为大于等于1的整数，所述控制信道单元包含时域上的至少一个符号和频域上的至少一个资源块或子载波。所述第一指示信息还可以用于指示所述第三资源中包含的所述控制信道单元的数量m与所述控制信道单元在时域上包含的符号数量和在频域上包含的资源块数量或子载波数量中的至少一种信息，或所述第三资源中包含的所述控制信道单元的数量m与所述控制信道单元在时域上包含的符号数量和在频域上包含的资源块数量或子载波数量中的至少一种信息为预定义的信息。所述第三资源所包含的m个控制信道单元按照时域优先或频域优先的方式映射到所述第二资源所包含的序号最小的子信道上。所述控制信道单元可以为用于发送V2X控制消息的控制信道单元(V2X Control Channel Element,V2X CCE)，所述V2X CCE在时域上占据一个或者多个符号，在频域上占据一个或者多个子载波或者资源块，例如所述V2X CCE的大小可以为在时域上占据1个符号以及在频域上占据2个资源块，所述V2X CCE的大小可以由第一指示信息指示，或者直接预定义，所述V2X CCE的数量m也可以由第一指示信息指示或者直接预定义。第一通信设备根据V2X CCE的大小以及数量m，按照时域优先或者频域优先的方式在所述第二资源所包含的序号最小的子信道上确定第三资源。
如图9所示，以一个时隙为例，一个时隙可以包含14个符号，一个时隙中的最后一个符号用于保护间隔，实际用于传输控制信息和数据的符号数为13。图9(a)和(b)分别给出了控制信息和数据资源映射的一种可能的示意图，即第三资源和第四资源的一种可能的配置情况。其中V2X CCE的数量m为4，V2X CCE在时域上占据1个符号以及在频域上占据2个资源块，子信道的带宽为6个资源块，所述第二资源在时域上占用一个时隙，在频域上占据2个子信道。图9(a)和(b)分别给出了4个所述V2X CCE按照频域优先和时域优先的资源映射情况，V2X CCE位于序号最小的子信道上，在图9(a)中，所述4个V2X CCE按照频域资源块符号从小到大的顺序排列，在第一个符号上排满6个资源块后，再排 列下一个符号所对应的资源块；在图9(b)中所述4个V2X CCE按照时域符号从小到大的顺序排列；所述4个V2X CCE组成了第三资源，第四资源为第二资源中除第三资源以外的部分。
