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是本发明实施例的系统的示意性架构图。
本发明实施例提供的基站可以为UMTS下的基站(Node B，NB)、LTE下的演进型基站(eNodeB，eNB)或者第五代移动通信系统下的基站或控制器。
本发明实施例提供的用户设备(User Equipment，UE)可以是但不限于移动台(MS，Mobile Station)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、手机(handset)及便携设备(portable equipment)等。
在本发明实施例中，基站发送控制信息给用户设备，基站根据控制信息来发送或接收数据。具体的，基站发送控制信息给用户设备，基站根据所述控制信息发送数据给用户设备，用户设备接收所述控制信息，并根据所述控制信息接收所述数据，或者，基站发送控制信息给用户设备，用户设备根据所述控制信息发送数据给基站，基站根据所述控制信息接收所述数据。
本发明实施例基于上述系统架构，需要说明的是，在不冲突的情况下，各个实施例以及实施例中的特征可以相互结合。
图2为本发明实施例提供的控制信息的发送方法，其步骤包括：
步骤21，基站发送第一控制信息给第一用户设备。可选的，第一控制信息为现有的控制信息，其包含资源分配信息、调制编码指示信息、混合自动重传请求进程号、新数据指示信息、物理上行控制信道的功控命令、解调导频的循环移位序列、物理上行数据信道的功控命令、信道质量指示或数据信 道指示信息至少之一。可选的，所述第一控制信息为下行控制信息(Downlink Control Information，DCI)或上行控制信息(Uplink Control Information，UCI)。
步骤22，所述基站根据所述第一控制信息与所述第一用户设备进行第一数据的传输。可选的，在下行数据传输时，所述基站根据所述第一控制信息，即DCI，向所述第一用户设备发送第一数据；在上行数据传输时，所述基站根据所述第一控制信息，即UCI，从所述第一用户设备接收第一数据。
步骤23，所述基站发送第一触发信息给所述第一用户设备。所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息与所述第一用户设备进行第二数据的传输。可选的，在下行数据传输时，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息向所述第一用户设备发送第二数据；在上行数据传输时，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息从所述第一用户设备接收第二数据。可选的，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息，即所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息，以及所述部分信息或全部信息具体为第一控制信息的哪些信息，与所述第一用户设备进行第二数据的传输。可选的，所述第二数据与所述第一数据为不同的数据。例如，所述第一数据和二数据均为编码前的源数据，所述第二数据与所述第一数据为不同的编码前的源数据。
通过上述方案，所述基站发送第一触发信息给所述第一用户设备，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息与所述第一用户设备进行第二数据的传输，因此，基站根据第一控制信息的部分或者全部信息与第一用户设备进行第二数据的传输，即基站与第一用户设备进行新的数据的传输时采用了之前的控制信息，而第一触发信息占用的资源要少于控制信息占用的资源，由此，提高了控制信道的利用效率，以满足大量设备的连接和大量的数据收发所带来的大量的控制信息的收发。
在可选的实施例中，所述基站发送第一触发信息给所述第一用户设备包括：所述基站发送第一控制消息给所述第一用户设备，其中，所述第一控制消息包含所述第一触发信息。可选的，所述第一控制消息由所述基站在下行控制信道上发送给所述第一用户设备，所述第一控制消息可以为新的控制信道格式，例如，通过一个用户的控制信道来承载另一个用户的触发信息。 基站配置M个UE为一个组。而且基站通知UE组内其他UE的小区无线网络临时标识(Cell-Radio network Temporary Identifier,C-RNTI)。又例如，第一控制消息可以定义一种新的控制信道格式，除了携带期望用户的调度信息，还携带其他用户的触发信息。此控制信道的循环冗余校验(Cyclic Redundancy Check，CRC)由期望用户的C-RNIT进行加扰。例如M＝3，一个组内有3个用户。基站将每个UE的C-RNTI通知给组内的用户，基站通过PDCCH发了一个下行PDSCH的调度给UE2，此PDCCH的CRC由UE2的C-RNTI加扰。同时，这个控制信道除了携带UE2的调度信息，比如format1A的调度信息，还携带了UE1和UE3的触发信息。再例如,第一控制消息可以定义一种新的控制信令格式，这个控制信令的负荷大小为L，L为加了CRC之前的这个控制信道的信息位的比特数，例如，这个控制信令的负荷和format 0的负荷大小一样；每个用户分配了X个比特的触发信息。在这个控制信道中，可以给
Figure PCTCN2015074294-appb-000007
个用户发送触发信息。这样，就节省了控制信道的数目。
在可选的实施例中，所述第一控制消息还包含至少一个第二触发信息，所述至少一个第二触发信息与所述第一触发信息为针对不同用户设备的触发信息。具体的，第二触发信息是基站发送给与所述第一用户设备不同的用户设备的触发信息，所述与所述第一用户设备不同的用户设备可以是多个，则此时，至少一个第二触发信息为多个与所述第一用户设备不同的用户设备对应的第二触发信息，可以理解，第二触发信息仅仅是与第一触发信息区别的名称，多个与所述第一用户设备不同的用户设备对应的多个第二触发信息可以是不相同的。
在可选的实施例中，所述第一触发信息或所述至少一个第二触发信息中的每条信息占用X个比特；所述第一控制消息可以包含的所述第一触发信息或所述至少一个第二触发信息的个数N满足公式：
Figure PCTCN2015074294-appb-000008
其中，所述L为所述第一控制消息信息位所占的比特数。例如表1所示，为下行数据传输时，所述第一触发信息或所述至少一个第二触发信息占用XDL个比特的情况。
表1

在可选的实施例中，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息与所述第一用户设备进行第二数据的传输，图2实施例所述方法还包括：所述基站根据所述第一控制信息的部分信息和所述第一触发信息包括的混合自动重传请求进程号、新数据指示信息、物理上行控制信道的功控命令、解调导频的循环移位序列、物理上行数据信道的功控命令、信道质量指示或数据信道指示信息至少之一，与所述第一用户设备进行第二数据的传输。例如表1中XDL＝7的情况，所述第一触发信息指示所述基站根据所述第一控制信息的部分信息向所述第一用户设备发送第二数据，其中所 述第一控制信息的部分信息为资源分配信息和调制编码指示信息，所述资源分配信息用于指示所述基站发送所述第一数据所占用的时频资源，则所述基站根据所述资源分配信息和调制编码指示信息，以及混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令向所述第一用户设备发送所述第二数据。此时，所述资源分配信息、调制编码指示信息是包含在所述第一控制信息中的，所述混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令等信息由所述第一触发信息所携带，所述第一触发信息除用于指示所述部分信息为资源分配信息和调制编码指示信息，还携带了混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令。又例如表2中XUL＝8的情况，所述第一触发信息指示所述基站根据所述第一控制信息的部分信息从所述第一用户设备接收第二数据，其中所述第一控制信息的部分信息为资源分配信息和调制编码指示信息，所述资源分配信息用于指示所述基站接收所述第一数据所占用的时频资源，则所述基站根据所述资源分配信息和调制编码指示信息，以及解调导频的循环移位序列、新数据指示信息、物理上行数据信道的功控命令以及信道质量指示从所述第一用户设备接收所述第二数据。此时，所述资源分配信息、调制编码指示信息是包含在所述第一控制信道中的，所述解调导频的循环移位序列、新数据指示信息、物理上行数据信道的功控命令以及信道质量指示由所述第一触发信息所携带，所述第一触发信息除用于指示所述部分信息为资源分配信息和调制编码指示信息，还携带了解调导频的循环移位序列、新数据指示信息、物理上行数据信道的功控命令以及信道质量指示。

在可选的实施例中，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息与所述第一用户设备进行第二数据的传输，图2实施例所述方法还包括：所述基站根据所述第一控制信息的部分信息和预定义的所述第一控制信息的除所述部分信息之外的控制信息，与所述第一用户设备进行第二数据的传输。例如表1中XDL＝7的情况，所述第一触发信息至少用于指示数据指示信息为所述第一控制信道的部分信息具体为资源分配信息和调制编码指示信息，所述资源分配信息用于指示所述基站发送所述第一数据所占用的时频资源，则所述基站根据所述资源分配信息和调制编码指示信息和预定义的混合自动重传请求进程号、预定义的新数据指示信息以及预定义的物理上行控制信道的功控命令向所述第一用户设备发送所述第二数据。其中，所述混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令等信息为预定义的。又例如表2中XUL＝7的情况，所述第一触发信息至少用于指示数据指示信息为所述第一控制信道的部分信息具体为资源分配信息和调制编码指示信息，所述资源分配信息用于指示所述基站发送所述第一数据所占用的时频资源，则所述基站根据所述资源分配信息和调制编码指示信息和预定义的混合自动重传请求进程号、预定义的新数据指示信息以及预定义的物理上行控制信道的功控命令从所述第一用户设备接收所述第二数据。其中，所述混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令等信息为预定义的。

通过上述方案，所述发送单元301发送第一触发信息给所述第一用户设备，所述第一触发信息用于指示所述传输单元302根据所述第一控制信息的部分信息或全部信息与所述第一用户设备进行第二数据的传输，因此，基站根据第一控制信息的部分或者全部信息与第一用户设备进行第二数据的传输，即基站与第一用户设备进行新的数据的传输时采用了之前的控制信息，而第一触发信息占用的资源要少于控制信息占用的资源，由此，提高了控制信道的利用效率，以满足大量设备的连接和大量的数据收发所带来的大量的控制信息的收发。
在可选的实施例中，所述发送单元301还用于发送第一触发信息给所述第一用户设备包括：所述发送单元301发送第一控制消息给所述第一用户设备，其中，所述第一控制消息包含所述第一触发信息。可选的，所述第一控制消息由所述发送单元301在下行控制信道上发送给所述第一用户设备，所述第一控制消息可以为新的控制信道格式，例如，通过一个用户的控制信道来承载另一个用户的触发信息。基站配置M个UE为一个组。而且基站通知UE组内其他UE的小区无线网络临时标识(Cell-Radio network Temporary Identifier,C-RNTI)。又例如，第一控制消息可以定义一种新的控制信道格式，除了携带期望用户的调度信息，还携带其他用户的触发信息。此控制信道的循环冗余校验(Cyclic Redundancy Check，CRC)由期望用户的C-RNIT进行加扰。例如M＝3，一个组内有3个用户。基站将每个UE的C-RNTI通知给组内的用户，基站通过PDCCH发了一个下行PDSCH的调度给UE2，此PDCCH的CRC由UE2的C-RNTI加扰。同时，这个控制信道除了携带UE2的调度信息，比如format 1A的调度信息，还携带了UE1和UE3的触发信息。再例如,第一控制消息可以定义一种新的控制信令格式，这个控制信令的负荷大小为L，L为加了CRC之前的这个控制信道的信息位的比特数，例如，这个控制信令的负荷和format 0的负荷大小一样；每个用户分配了X个比特的触发信息。在这个控制信道中，可以给

下面结合具体例子，更加详细地描述本发明的实施例。
图10为本发明实施例提供的下行数据传输时控制信息的传输方法，具体步骤包括：
步骤101，基站发送第一控制信息给UE1，UE1接收所述第一控制信息。可选的，第一控制信息为现有的控制信道，其包含资源分配信息、调制编码指示信息、混合自动重传请求进程号、新数据指示信息、物理上行控制信道的功控命令、解调导频的循环移位序列、物理上行数据信道的功控命令、信道质量指示或数据信道指示信息至少之一。例如，对于下行数据传输的控制信道在LTE版本8中Format 1A包含如下信息比特：

个比特；
调制编码指示信息5比特；
新数据指示信息1比特；
物理上行数据信道的工控命令2比特；
解调导频的循环移位3比特；
信道质量指示信息1bit。
步骤102，所述基站根据所述第一控制信息向所述UE1发送第一数据，UE1则根据所述第一控制信息接收所述第一数据。
步骤103，UE1向所述基站发送确认消息，所述基站从所述UE1接收确认消息。其中，所述确认消息用于所述UE1通知所述基站所述UE1根据所述第一控制信道接收所述第一数据成功。可选的，所述UE1在步骤101之后且在步骤104之前的任何时间点存储所述第一控制信道。可选的，UE1只有在下行数据传输时才向所述基站发送确认消息，对于上行数据传输的情况，UE1无需发送确认消息给所述基站。可选的，所述步骤103不是必需的，即在所述步骤102后直接执行步骤104。
步骤104，所述基站发送第一触发信息给所述UE1，UE1接收所述第一触发信息。其中，所述第一触发信息是所述基站接收所述确认消息后发送给所述UE1的，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息与所述第一用户设备进行第二数据的传输。
步骤105，所述基站根据所述第一控制信息的部分信息或全部信息向所述UE1发送所述第二数据，UE1则根据所述第一控制信息的部分信息或全部信息从所述基站接收所述第二数据。
通过上述方案，基站发送第一触发信息给用户设备，可选的，第一触发信息是所述基站接收所述确认消息后发送给所述UE1的，所述第一触发信息用于指示所述基站根据所述第一控制信息的部分信息或全部信息与所述第一用户设备进行第二数据的传输。因此，基站根据第一控制信道的信息给UE1发送第二数据，即基站发送新的数据时采用了之前的控制信道，而第一触发信息占用的资源要少于控制信道占用的资源，由此，提高了控制信道的利用效率，以满足大量设备的连接和大量的数据收发所带来的大量的控制信息的收发。
在可选的实施例中，所述基站发送第一触发信息给所述UE1包括：所述基站发送第一控制消息给所述UE1，其中，所述第一控制消息包含所述第一触发信息。可选的，所述第一控制消息由所述基站在下行控制信道上发送给所述第一用户设备，所述第一控制消息可以为新的控制信道格式，例如，通过一个用户的控制信道来承载另一个用户的触发信息。基站配置M个UE为一个组。而且基站通知UE组内其他UE的小区无线网络临时标识(Cell-Radio network Temporary Identifier,C-RNTI)。又例如，第一控制消息可以定义一种新的控制信道格式，除了携带期望用户的调度信息，还携带其他用户的触发信息。此控制信道的循环冗余校验(Cyclic Redundancy Check，CRC)由期望用户的C-RNIT进行加扰。例如M＝3，一个组内有3个用户。基站将每个UE的C-RNTI通知给组内的用户，基站通过PDCCH发了一个下行PDSCH的调度给UE2，此PDCCH的CRC由UE2的C-RNTI加扰。同时，这个控制信道除了携带UE2的调度信息，比如format 1A的调度信息，还携带了UE1和UE3的触发信息。再例如,第一控制消息可以定义一种新的控制信令格式，这个控制信令的负荷大小为L，L为加了CRC之前的这个控制信道的信息位的比特数，例如，这个控制信令的负荷和format 0的负荷大 小一样；每个用户分配了X个比特的触发信息。在这个控制信道中，可以给
Figure PCTCN2015074294-appb-000018
个用户发送触发信息。这样，就节省了控制信道的数目。
在可选的实施例中，所述第一控制消息还包含至少一个第二触发信息，所述至少一个第二触发信息与所述第一触发信息为针对不同用户设备的触发信息。具体的，第二触发信息是基站发送给与所述UE1不同的用户设备的触发信息，所述与所述第一用户设备不同的用户设备可以是多个，例如UE2，UE3等等，则此时，至少一个第二触发信息为多个与所述UE1不同的用户设备对应的第二触发信息，可以理解，第二触发信息仅仅是与第一触发信息区别的名称，多个与所述UE1不同的UE2、UE3等等对应的多个第二触发信息可以是不相同的，如，与UE1对应的触发信息1，与UE2对应的触发信息2，与UE3对应的触发信息3等等。
在可选的实施例中，所述第一触发信息或所述至少一个第二触发信息占用X个比特；
所述第一控制消息可以包含的所述第一触发信息或所述至少一个第二触发信息的个数N满足公式：

在可选的实施例中，所述第一触发信息用于指示所述基站根据所述第一控制信道的全部信息与所述UE1进行第二数据的传输。所述基站根据所述第一控制信道的全部信息向所述UE1发送所述第二数据。例如表3中XDL＝1的情况，所述第一触发信息用于指示所述基站与所述UE1进行第二数据传输所根据的第一控制信息的全部信息为资源分配信息、调制编码指示信息、混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令，所述资源分配信息用于指示所述基站发送所述第一数据所占用的时频资源，则所述基站根据所述资源分配信息、调制编码指示信息、混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令向所述UE1发送所述第二数据。此时，所述资源分配信息、调制编码指示信息、混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令都是包含在所述第一控制信道中的，所述第一触发信息只用于指示所述基站根据所述第一控制信息的全部信息与所述UE1进行第二数据的传输，而所述第一触发信息用于指示基站向所述UE1发送所述第二数据所根据的数据指示信息为所述第一控制信道的全部信息。
在可选的实施例中，所述第一触发信息用于指示所述基站根据第一控制信息的部分信息与所述UE1进行第二数据的传输，所述基站根据所述第一控制信道的部分信息和预定义的所述第一控制信道的除所述部分信息之外的控制信息，向所述UE1发送所述第二数据。例如表3中XDL＝7的情况， 所述第一触发信息用于指示所述基站与所述第一用户设备进行第二数据传输所根据的第一控制信息的部分信息，以及预定义的混合自动重传请求进程号、预定义的新数据指示信息以及预定义的物理上行控制信道的功控命令向所述UE1发送所述第二数据，所述第一控制信道的部分信息具体为资源分配信息和调制编码指示信息，所述资源分配信息用于指示所述基站发送所述第一数据所占用的时频资源，则所述基站根据所述资源分配信息和调制编码指示信息和预定义的混合自动重传请求进程号、预定义的新数据指示信息以及预定义的物理上行控制信道的功控命令向所述UE1发送所述第二数据。其中，所述混合自动重传请求进程号、新数据指示信息以及物理上行控制信道的功控命令等信息为预定义的。
