具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中，在车联网中，受远距离传输或车辆快速移动的影响，可能信道衰落严重，接收时的信号功率大大降低。由于设备射频端器件的限制，当接收功率剧烈变化时，射频放大器AGC(Automatic Gain Control，自动增益控制)需要一定的时间进行调整。另外，在车联网中，通常先传输控制信息，后传输用户数据，控制信息往往占用时隙中的起始时域符号。但是，控制信息的容错率较低，使得AGC的调整可能导致控制信息无法正确接收和解码。
为解决上述问题，本实施例尽量避免控制信息仅占用时间单元的起始符号，以尽量保证 控制信息的正确接收和解码。
图1是根据一示例性实施例示出的一种传输控制信息和数据的方法的流程图，该传输控制信息和数据的方法用于用户设备中，其中，用户设备可以是移动电话，计算机，数字广播用户设备，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图1所示，该方法包括以下步骤101-102。
在步骤101中，确定待发送的控制信息和用户数据对应的时频资源。
在步骤102中，在所述时频资源上传输所述控制信息和用户数据。
其中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于同一时间单元时，部分所述第二时频资源占用所述时间单元的起始时域符号；和/或
当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于不同的时间单元时，所述第一时频资源至少占用第一时间单元的一半时域符号。
本实施例中的用户设备适用于车联网中的用户设备，可以是车载用户设备，可以也路边用户设备等。
本实施例中的时间单元，可以是以一个时隙作为一个时间单元，或者是以一定数量的时域符号作为一个时间单元。
本实施例中的一种实现方式是，控制信息和用户数据可以位于同一时间单元，而此时部分用户数据占用时间单元的起始时域符号。因为用户数据的容错率较高，在AGC调整的影响下，也可以通过信道解码的纠错能力而获得正确的用户数据。控制信息尽量位于时间单元中考前位置，所以部分用户数据位于控制信息之前的时域符号位置，其余部分用户数据位于控制信息之后的时域符号位置。这样，有利于控制信息和用户数据的尽快解码。本实施例中控制信息可以尽可能的占用较少的时域符号。
本实施例中的另一种实现方式是，控制信息和用户数据可以位于不同的时间单元，而此时控制信息独立占用一个时间单元，且至少占用第一时间单元的一半时域符号。这样，由于控制信息占用了较多的时域符号，在信道解码的纠错能力下，也可以保证控制信息的正确解码。其中，控制信息所在的第一时间单元与用户数据所在的第二时间单元可以连续也可以不连续。
在一个实施例中，所述起始时域符号的数量是根据传输控制信息和用户数据所在频段和所使用的子载波间隔确定的。
本实施例中起始时域符号的数量K可以预先配置。例如当工作在频率范围1(小于6GHz)的载波上时，AGC调整时间最大约为15us，子载波间隔一般最大为30KHz和60KHz，一个slot(时隙)(14个时域符号)的长度为0.5ms和0.25ms，AGC调整时间只会影响到初始时域符号，可以设置K＝1；而当工作在频率范围2(大于6GHz)的载波上时，AGC的最大调整时间约为10us，子载波间隔一般最大为120KHz，一个slot长度为0.125ms，AGC调整时间可以最多影响到两个时域符号，可以设置K＝2。
子载波间隔越大，一个时域符号的时间长度越短，因此给定AGC调制时间，K的取值可 能越大。为了减少解码延迟，使控制信息尽可能位于时间单元中考前的位置，控制信息之前的用户数据占用越少的时域符号越好，同时又要避免AGC调整对控制信息的影响。所以，控制信息之前的用户数据占用的起始时域符号的数量满足所述K值即可。
在一个实施例中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于同一时间单元时，控制信息与用户数据可以占用相同的频域起始位置和带宽，也可以占用不同的频域起始位置和带宽。控制信息与用户数据也可以占用相同的时域符号，也可以占用不同的时域符号。控制信息之前的部分用户数据与控制信息之后的部分用户数据，可以占用相同的频域起始位置和带宽，也可以占用不同的频域起始位置和带宽。
如图2-图5所示，图2中控制信息201与控制信息201之前的用户数据202，以及与控制信息201之后的用户数据202，均位于相同的频率位置和带宽。但是控制信息201与用户数据202占用不同的时域符号。
图3中，部分用户数据202与控制信息201占用了相同的时域符号，占用不同的频率位置和带宽。除这部分用户数据202以外的其它用户数据202，与控制信息201位于相同的频率位置和带宽。
图4中，控制信息201之前的部分用户数据202与控制信息201位于相同的频率位置和带宽，控制信息201与其之后的部分用户数据202位于相同的频率起始位置，但是位于不同的带宽。
图5中，控制信息201与用户数据202位于不同的频率位置和带宽。控制信息201之前的部分用户数据202与控制信息201之后的部分用户数据202，位于相同的频率起始位置和带宽。
在一个实施例中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于不同的时间单元时，控制信息与用户数据可以占用相同的频域起始位置和带宽，也可以占用不同的频域起始位置和带宽。如图6所示，图6中控制信息201与用户数据202占用不同的频域起始位置和带宽。
在一个实施例中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于同一时间单元时，位于所述控制信息之前的部分数据单元与位于所述控制信息之后的部分数据单元的发送功率相同。
本实施例中尽可能减少同一时间单元内发送功率的调整，也就是减少对接收端的影响。
在一个实施例中，所述控制信息和/或所述用户数据包括解调参考信号。
为了尽可能快的解码控制信息和用户数据，解调参考信号在时间单元中的位置尽可能靠前，所以本实施例中解调参考信号可以位于控制信息所在的第一时频资源，也可以位于控制信息之前的部分用户数据所在的第二时频资源。
如图7-图9所示，图7中，解调参考信号203位于控制信息之前的部分用户数据所在的第二时频资源，且占用了控制信息之前的部分用户数据的全部时频资源，相当于控制信息之前的部分用户数据全部为解调参考信号。
图8中，部分解调参考信号203位于第一时频资源，部分解调参考信号203位于控制信息之前的第二时频资源，相当于控制信息和用户数据均包括解调参考信号。
图9中，解调参考信号203位于第一时频资源，相当于控制信息包括解调参考信号。
本实施例中解调参考信号的位置可以灵活配置，适用于多种应用环境。
在一个实施例中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于同一时间单元时，第一时频资源和第二时频资源属于第一资源池。
当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于不同的时间单元时，第一时频资源和第二时频资源属于第二资源池，其中，第一资源池与第二资源池在时频资源上不重合。
本实施例中可以兼容上述两种情况，通过不同的资源池来将两种情况分开。如图10所示，第一资源池与第二资源池可以位于不同的频域，或者位于不同的时域。第一资源池与第二资源池的大小也可以灵活配置。第一资源池与第二资源池在时频资源上可以交替出现。
一个用户设备可以只在一种资源池中传输信息，也可以在两种资源池中传输信息。网络侧可以通过下行信令来通知用户设备其适用于哪种资源池，以及关于资源池的相关配置信息，如资源池的时频资源及周期长度等。
以上实施例可以根据实际需要进行自由组合。
下述为本发明装置实施例，可以用于执行本发明方法实施例。
图11是根据一示例性实施例示出的一种传输控制信息和数据的装置的框图，该装置可以通过软件、硬件或者两者的结合实现成为电子设备的部分或者全部。参照图11，该传输控制信息和数据的装置包括确定模块1101和传输模块1102；其中：
确定模块1101，用于确定待发送的控制信息和用户数据对应的时频资源。
传输模块1102，用于在所述时频资源上传输所述控制信息和用户数据。
其中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于同一时间单元时，部分所述第二时频资源占用所述时间单元的起始时域符号。
和/或，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于不同的时间单元时，所述第一时频资源至少占用第一时间单元的一半时域符号。
在一个实施例中，所述起始时域符号的数量是根据传输控制信息和用户数据所在频段和所使用的子载波间隔确定的。
在一个实施例中，当所述控制信息对应的第一时频资源和所述用户数据对应的第二时频资源属于同一时间单元时，位于所述控制信息之前的部分数据单元与位于所述控制信息之后的部分数据单元的发送功率相同。
在一个实施例中，所述控制信息和/或所述用户数据包括解调参考信号。
