技术领域
本发明涉及通信领域，尤其涉及一种控制信息传输方法及装置。
背景技术
通信系统通常使用不同种类的参考信号：一类参考信号用于信道估计，从而可以对接收信号进行相干解调；另一类用于信道状态或信道质量的测量，从而实现对终端(user equipment，简称UE，也称用户设备)的调度。在第三代合作伙伴项目(the 3rd generation partnership project，简称3GPP)长期演进(long term evolution，简称LTE)第10版本(release10，简称R10)下行系统中，用于相干解调的参考信号被称为解调参考信号(demodulation reference signal，简称DMRS)，用于信道状态信息测量的参考信号被称为信道状态信息参考信号(channel state information reference signal，简称CSI-RS)。
现有技术中定义了用于信号传输的10种传输模式和对应的7种传输机制，以及多种下行控制信息(downLink control information，简称DCI)格式。每一种传输模式和传输机制下有该传输模式或传输机制特定的DCI格式。
未来5G系统的空口需被重新设计，因此需要一种新的控制信息传输方法。

具体实施方式
如背景技术中所述，现有技术中定义了10种传输模式和对应的7种传输机制，以及多种DCI格式。终端的反馈模式与传输模式绑定，不同的传输模式下同时有不同的反馈模式。因此，过多的传输模式或传输机制以及对应的DCI格式，会导致终端在不同传输模式间的无线资源控制(radio resource control，简称RRC)频繁重配，增加终端的盲检复杂度。
未来5G系统的空口需被重新设计，包括数据传输的传输模式或传输机制，以及与传输模式或传输机制对应的DCI格式等。因此，需要定义新的简化的传输机制以及相应的控制信息格式。
基于此，本发明实施例提供了一种控制信息传输方法及相关设备。本发明实施例可适用于下行数据传输对应的控制信息传输，也可适用于上行数据传输对应的控制信息传输。本发明实施例中涉及的控制信息可以是指下行数据传输对应的下行控制信息，也可以是指上行数据传输对应的下行控制信息。更进一步地，所述控制信息可以是指下行控制信息，也可以是指上行控制信息。
在本发明实施例中，对于控制信息传输来说，所涉及到的设备包括控制信息的发送设备和控制信息的接收设备。所述发送设备可以配置所述接收设备进行信道测量和反馈，所述发送设备可以根据所述接收设备的反馈确定使用的传输机制，并将该传输机制相关的控制信息发送给所述接收设备。其中，在下行或上行数据传输对应的下行控制信息传输中，所述发送设备可以是基站或其他类型的传输点设备，所述接收设备可以是终端或者其他能够实现类似功能的设备；在上行控制信息传输中，所述发送设备可以是终端或者其他能够实现类似功能的设备，所述接收设备可以是基站或其他类型的传输点设备。当然不也限于上述两种设备。
其中，基站可以是LTE系统或其演进系统中的演进型基站(Evolutional Node B，简称为eNB或e-NodeB)、宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point，简称为AP)或传输站点(transmission point，简称为TP)等，也可以是未来网络中的基站，如5G网络中的基站。
在本发明实施例中，终端也可称为用户设备(比如UE)，或者可称之为terminal、移动台(mobile station，简称为MS)、移动终端(mobile terminal)等，该终端可以经无线接入网(radio access network，简称为RAN)与一个或多个核心网进行通信，例如，终端可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，例如，终端还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。本发明实施例中的终端还可以是设备与设备(device to device，简称D2D)终端或者机器与机器(machine to machine，简称M2M)终端。
为描述方便，下述实施例将以基站作为下行控制信息的发送设备，以终端作为下行控制信息的接收设备为例进行说明。
本发明实施例可适用于无线通信网络，例如，LTE系统或其演进系统，宽带码分多址(wideband code division multiple access，简称WCDMA)系统等，在此不再一一列举。图1示例性地示出了无线通信网络中与本发明实施例相关的架构，其中，基站和终端之间可进行上行(即终端到基站)传输和下行(即基站到终端)传输。
本发明实施例定义了以下几种传输机制，这些传输机制可适用于5G系统：
(1)发射分集，可包括基于DMRS的发射分集和/或基于小区级参考信号的发射分集。其中，基于DMRS的发射分集是指数据传输的发射模式为基于DMRS作为解调参考信号的分集机制；基于小区级参考信号的发射分集是指数据传输的发射模式为基于小区级参考信号作为解调参考信号的分集机制。
(2)开环传输，可包括基于DMRS的开环传输和/或基于小区级参考信号的开环传输。其中，基于DMRS的开环传输指的是数据传输的发射模式为基于DMRS作为解调参考信号的开环机制；基于小区级参考信号的开环传输指的是数据传输的发射模式为基于小区级参考信号作为解调参考信号的开环机制。
(3)半开环传输，可包括基于DMRS的半开环传输和/或基于小区级参考信号的半开环传输。其中，基于DMRS的半开环传输指的是数据传输的发射模式为基于DMRS作为解调参考信号的半开环机制；基于小区级参考信号的半开环传输指的是数据传输的发射模式为基于小区级参考信号作为解调参考信号的半开环机制。可选地，半开环传输可以为介于开环传输和闭环传输之间的一种传输机制。
(4)闭环传输，可包括基于DMRS的闭环传输和/或基于小区级参考信号的闭环传输。其中，基于DMRS的闭环传输指的是数据传输的发射模式为基于DMRS作为解调参考信号的闭环机制；基于小区级参考信号的闭环传输指的是数据传输的发射模式为基于小区级参考信号作为解调参考信号的闭环机制。
当然，上述传输机制的命名仅为一种示例，本发明实施例并不排除其他命名方式。上述传输机制是指广义的传输机制。所述广义的传输机制定义既适用于下行数据传输，也适用于上行数据传输。
需要说明的是，以上仅示例性地列举出了几种传输机制，本发明实施例允许定义其他类型的传输机制或者定义更多种类型的传输机制。例如，上述发射分集进一步可包括波束域的发射分集，所述波束域的发射分集指的是采用至少两个波束进行相同内容的待传输信息的发送。
下面的实施例以上述四种传输机制为例进行描述。
本发明实施例给出了三种控制信息传输方案(方案一、方案二和方案三)，下面分别对这三种方案分别进行描述。
在方案一和方案二中，控制信息的发送设备发送的控制信息与上述传输机制中的一种相关联，具体可通过所发送的控制信息中包含的用于指示传输机制类型的信息来指示该控制信息所关联的传输机制。
可采用隐式方式指示控制信息所关联的传输机制，即，可通过控制信息中包含的某个或某些控制信息来指示该控制信息所关联的传输机制的类型。考虑到一些实施例中，传输机制的类型与信道传输的空间层数或码字个数有关，因此控制信息所关联的传输机制的类型，可根据该控制信息所使用的控制信息格式中与信道传输的空间层数或码字个数有关的信息域进行指示。比如，在下行数据传输对应的下行控制信息传输中，如果下行控制信息 所使用的DCI格式中，信道传输的空间层数为1(即基站到终端的信道传输层数等于1)，则该下行控制信息关联的传输机制为发射分集；如果下行控制信息所使用的DCI格式中，信道传输的空间层数为2(即基站到终端的信道传输层数等于2)，则该下行控制信息关联的传输机制为开环传输；如果下行控制信息所使用的DCI格式中，信道传输的空间层数大于4(即基站到终端的信道传输层数大于4)，则该下行控制信息关联的传输机制为闭环传输。需要说明的是，所述方法同样适用于上行数据传输对应的下行控制信息传输，这里不再重复。
也可采用显式方式指示控制信息所关联的传输机制。本发明实施例可扩展控制信息格式，在控制信息格式中定义一种信息域用来承载传输机制指示信息，以指示传输机制的类型。
无论采用隐式方式还是显式方式对控制信息所关联的传输机制的类型进行指示，对于控制信息的接收设备来说，均可根据接收到的控制信息确定其所关联的传输机制的类型，从而可以采用相应类型的传输机制进行传输。当控制信息的发送设备决策对某接收设备的传输机制从第一传输机制改变为第二传输机制时(其中，第一传输机制和第二传输机制可以是上述传输机制中的两种不同的传输机制)，可向接收设备发送与第二传输机制关联的控制信息，接收设备根据接收到的控制信息进行相应设置，并采用第二传输机制与发送设备进行通信，从而可实现在不同传输机制间进行快速和动态的切换。
下面分别对上述方案一、方案二和方案三进行详细描述。
方案一
本发明方案一的实施例简化了控制信息格式的设计，可以使得上述所有传输机制对应的控制信息使用不超过两种控制信息格式。具体地，方案一提供了两种控制信息格式：第一控制信息格式和第二控制信息格式。其中，对于第一控制信息格式和第二控制信息格式的命名方式，本发明实施例不作限制。
下面以下行数据传输对应的下行控制信息传输为例描述方案一的具体实现方式。
本发明实施例定义了第一DCI格式和第二DCI格式。第一DCI格式主要用于公共系统信息的控制信息指示，即，使用第一DCI格式传输的控制信息主要包括公共系统信息对应的控制指示信息，如，用于广播信道发送的控制指示。举例来说，第一DCI格式可承载以下控制信息中的一种或多种：寻呼信息的控制指示信息，随机接入响应的控制指示信息、动态广播信道的控制指示信息和系统信息的控制指示信息等。
可选地，第一DCI格式中可包括以下信息域：
-测量间隔指示域，用于指示测量间隔(measurement GAP)值，该信息域的信息比特数量可以是1比特；
-资源分配指示域，用于指示紧凑调度的资源块分配(resource block assignment for compact scheduling)，该信息域的信息比特数量可以是x比特，x为大于等于1的整数；
-调制与编码方案(modulation and coding scheme，简称MCS)指示域，用于指示MCS值，该信息域的信息比特数量可以是5比特；
-多播控制信道(multicast control channe，简称MCCH)通知信息指示域，用于承载MCCH变更通知信息(information for MCCH change notification)或该MCCH变更通知信息的指示信息，该信息域的比特数量可以是8比特；
-预留的信息域，预留的信息比特域，当下行控制信息的信息比特数量未达到一个物 理下行共享信道(physical downlink shared channel，简称PDSCH)码字的紧凑调度格式1C的大小时，可用预留信息域进行填充，以使下行控制信息的信息比特数量与一个PDSCH码字的紧凑调度格式1C的大小相等。此外，第一DCI格式中还可进一步包括一些用于5G系统的公共系统信息的控制信息指示的新指示域。这里不做限定。
使用第二DCI格式传输的控制信息主要包括用户专用信道的控制信息指示，即，第二DCI格式传输的控制信息主要包括用户专用控制信息，如，用于用户专用信道发送的控制指示。举例来说，第二DCI格式可承载以下控制信息中的一种或多种：信道传输的空间层数的指示，码字到层映射的指示，资源分配相关的调度信息等。
可选地，第二DCI格式中可包含以下信息域：
-传输机制指示域，用于承载传输机制指示信息(transmission scheme indicator)，
比如承载传输机制类型的指示信息。可选地，该信息域的信息比特数量可以是1
比特或2比特，用来指示传输机制的动态切换。
如果传输机制指示域的信息比特数等于2，则该2比特的传输机制指示域用于承载传输机制类型的指示信息(比如索引值)。表1示例性地示出了该指示域的每个状态值(即传输机制类型的索引值)：
表1：2比特的传输机制指示域的状态值
Figure PCTCN2017097118-appb-000001
可选地，表2示例性地示出了另一种该指示域的每个状态值(即传输机制类型的索引值)的实施方式：
表2：2比特的传输机制指示域的状态值
Figure PCTCN2017097118-appb-000002
在终端侧，终端可接收基站按照上述方法发送的下行控制信息，根据接收到的第二DCI格式中的2比特的传输机制指示域的状态值，确定下行控制信息所关联的传输机制。
如果传输机制指示域的信息比特数等于1，则1比特长度的信息域用于承载码字与传输机制的映射关系的指示信息，该指示信息可指示每个码字分别对应的传输机制类型。
可选地，所述1比特的传输机制指示域可以通过复用当前LTE系统中的如下信息域来 实现：传输块到码字交换标志(transport block to codeword swap flag)，该信息域为1比特信息域。其中，该指示域的每个状态值(即传输机制指示信息的取值)可如表3所示：
表3：1比特的传输机制指示域的状态值
状态值 码字0 码字1
0 发射分集 开环传输
1 闭环传输 闭环传输
可选地，表4示例性地示出了另一种该指示域的每个状态值(即传输机制类型的索引值)的实施方式：
表4：1比特的传输机制指示域的状态值
状态值 码字0 码字1
0 开环传输 开环传输
1 闭环传输 闭环传输
根据表3，当传输机制指示域的状态值等于0时，码字0采用发射分集或开环传输机制，码字1采用开环传输；当传输机制指示域的状态值等于1时，码字0采用闭环传输，码字1采用闭环传输。在终端侧，终端可接收基站按照上述方法发送的下行控制信息，根据接收到的第二DCI格式中的1比特的传输机制指示域的状态值，确定每个码字使用的传输机制。
可选地，第二DCI格式中可包括以下信息域中的一个或多个：
-层指示域，用于承载信道传输的空间层数的指示信息，该信息域的比特数量可以是x比特，x为大于0的整数。
层指示域为可选项，根据传输机制的种类而有所取舍。比如，层指示域在闭环传输机制下的信息比特个数为x(x>0)，而在开环传输机制或发射分集下的信息比特个数为0，也就是说，在闭环传输机制下存在层指示信息域，而在开环传输机制或发射分集下则没有层指示信息域。因此可根据第二DCI格式中是否存在层指示域，得知通过该第二DCI格式发送的下行控制信息所关联的传输机制是否是闭环传输机制。
-非周期参考信号速率匹配指示域，用于承载非周期参考信号速率匹配的指示信息，该信息域的比特数量可以是y比特，y为大于0的整数。该非周期参考信号可以是CSI-RS。
非周期CSI-RS速率匹配指示域为可选项，根据传输机制的种类而有所取舍。比如，非周期CSI-RS速率匹配指示域，在闭环传输机制下的信息比特个数为y(y>0),而在开环传输机制或发射分集下的信息比特个数为0。也就是说，在闭环传输机制下存在非周期CSI-RS速率匹配指示域，而在开环传输机制或发射分集下则没有非周期CSI-RS速率匹配指示域。因此可根据第二DCI格式中是否存在非周期CSI-RS速率匹配指示域，得知通过该第二DCI格式发送的下行控制信息所关联的传输机制是否是闭环传输机制。
-发射预编码矩阵指示(transmit precoding matrix indicator，简称TPMI)指示域，用于承载TPMI，该信息域的比特数量可以是z比特，z为大于0的整数。
TPMI指示域为可选项，根据传输机制的种类而有所取舍。TPMI指示域在基于非DMRS的传输机制(比如基于小区级参考信号的闭环传输或基于小区级参考信号的开环传输)下的信息比特个数为z(z>0)，而在基于DMRS的闭环传输机制下的信息比特个数为0。也就是说，在基于DMRS的闭环传输机制下不存在TPMI指示域，而在基于非DMRS的传输机制下则存在TPMI指示域。因此可根据第二DCI格式中是否存在TPMI指示域，得知通过该第二DCI格式发送的下行
控制信息所关联的传输机制是否是基于DMRS的闭环传输机制。
根据上述描述可以看出，不同传输机制的下行控制信息使用的第二DCI格式中，可包含不同的信息域。进一步地，不同传输机制的下行控制信息使用的第二DCI格式中，用于承载相同类型下行控制信息的信息域的信息比特数量可以不同。具体实施时，为了使不同传输机制下的第二DCI格式的信息比特数量相同，可以通过补零的方法来实现不同传输机制下的第二DCI格式比特数都相同。
以上实施例虽然以下行数据或信号传输对应的控制信息为例描述，但上述实施例的实现原理也可适用于上行数据或信号传输对应的控制信息。在上行数据或信号传输对应的控制信息及控制信息格式中，除用于公共系统信息的控制指示信息不支持外，用于用户专用信道的第二控制信息格式可承载的内容以及可包含的信息域可同前所述，在此不再重复。同理，第二控制信息格式主要用于用户上行专用信道(如物理上行共享信道(physical uplink shared channel，PUSCH)的控制指示信息。
图2示出了本发明实施例提供的适合于方案一的控制信息(如下行数据传输对应的下行控制信息，或上行数据传输对应的下行控制信息)传输流程示意图，该流程可包括如下步骤：
步骤201：控制信息的发送设备发送控制信息，该控制信息与上述几种传输机制中的一种传输机制相关联，并且其中包含用于指示传输机制类型的信息。该控制信息使用的控制信息格式可包括第一格式和/或第二格式，其中，第一格式用于公共系统信息的控制信息指示，第二格式用于用户专用信道的控制信息指示。该步骤中，控制信息发送设备发送控制信息的方式可参见前述描述。
步骤202：控制信息的接收设备接收发送设备发送的控制信息，并进一步根据接收的控制信息进行相应处理。
该步骤中，接收设备可根据第二格式中包含的信息域判断控制信息对应的传输机制类型，进而采用该传输机制进行数据传输。
在接收设备侧，接收设备可接收发送设备按照上述方法发送的控制信息，根据接收到的第二格式中的相关信息域确定该控制信息所关联的传输机制。比如，终端可根据第二格式中的传输机制指示域的状态值确定该控制信息所关联的传输机制，终端也可以根据第二格式中的层指示域的状态值确定该控制信息所关联的传输机制，终端还可以结合多个信息域的状态值确定该控制信息所关联的传输机制。比如，接收设备根据第二格式中的传输机制指示域的状态值确定传输机制为闭环传输，由于第二格式中还包含TPMI指示域，因此确定该第二格式承载的控制信息所关联的传输机制为基于小区级参考信号的闭环传输机制。
通过以上对方案一的描述可以看出，控制信息的发送设备所发送的控制信息与至少两种传输机制中的一种传输机制相关联，并且该控制信息中包含用于指示传输机制类型的 信息，这样，可使控制信息的接收设备根据接收到的控制信息确定出对应的传输机制，进而当控制信息的发送设备需要切换传输机制时，可发送相应的控制信息，以使接收设备根据该控制信息切换到相应的传输机制。比如，如当信道条件较好时，基站使用第二DCI格式发送下行控制信息，其中传输机制指示域的状态值等于3，以指示终端采用闭环方式进行数据传输，当信道条件恶化时，基站使用第二DCI格式发送下行控制信息，其中传输机制指示域的状态值等于2，以指示终端采用开环方式进行数据传输。
方案二
方案二提供的实施例中，简化了控制信息格式的设计，可以使得上述所有传输机制对应的控制信息使用不超过三种控制信息格式，具体地可包括第三控制信息格式、第四控制信息格式和第五控制信息格式。其中，对于上述控制信息格式的命名方式，本发明实施例不作限制。
下面以下行数据传输对应的下行控制信息传输为例描述方案二的具体实现方式。
以下行数据传输对应的下行控制信息传输为例，本发明实施例定义了第三DCI格式、第四DCI格式和第五DCI格式。可规定上述四种传输机制中的第一传输机制，其一部分下行控制信息使用第三DCI格式，另一部分下行控制信息使用第四DCI格式。本实施例中，考虑到闭环传输作为未来5G通信系统的一种重要传输机制，针对该传输机制新增加的特性，可将该传输机制对应的新增信息比特通过第四DCI格式发送，即，5G系统演进所引入的新信息域可放在第四DCI格式中，因此第四DCI格式的大小可根据闭环传输机制的演进进行设计。可选地，方案二中的第四DCI格式，可参考方案一中的第二DCI格式进行设计。而对除闭环传输外的其他传输机制来说，其下行控制信息使用第三DCI格式。
以所述第一传输机制为闭环传输为例，第五DCI格式主要用于公共系统信息的控制信息指示，第三DCI格式主要用于传输上述四种传输机制所共有的用户专用信道的控制指示信息；第四DCI格式用于传输闭环传输机制所特有的用户专用信道的控制指示信息。
可选地，第三DCI格式中可包括以下信息域中的至少一种：
-载波指示域；
-资源分配类型指示域(资源分配类型的指示)；
-资源块分配指示域；
-功控命令字指示域；
-混合自动重传请求(hybrid Automatic retransmission request,简称HARQ)进程数指示域；
-HARQ偏移量指示域；
-调制编码方式指示域；
-新数据传输指示域；
-冗余版本指示域；
-预编码信息指示域；
-传输块到码字映射交换指示域。
第三DCI格式中的某个或某些信息域可隐式地指示是否存在第四DCI格式。比如，上述传输块到码字映射交换指示域，当所述指示域的取值为0时，对应了不进行传输块在至少两个码块间的交换映射，而当所述指示域的取值为1时，对应了进行传输块在至少两个码块间的交换映射。当所述指示域的值为0时同时隐式指示了不存在第四DCI格式，而当 所述指示域的值为1时同时隐式指示了存在第四DCI格式。
可选地，第三DCI格式中可包含第一信息域，该第一信息域用于承载第四DCI格式的指示信息，该指示信息可显式地指示是否存在第四DCI格式。可选地，第三DCI格式中用于第四DCI格式指示的信息域可如下所示：
第二级DCI格式指示域，用于承载第四DCI格式指示，该信息域的比特数量可以是1或2。
当第三DCI格式中该第一信息域中的指示信息的取值指示存在第四DCI格式时，则表明发送设备(如基站)还通过第四DCI格式发送了闭环传输机制下的下行控制信息，接收设备(如终端)可根据该第一信息域的取值判断发送设备(如基站)发送的下行控制信息是否是闭环传输机制下的下行控制信息，进而判断是否需要检测与接收通过第四DCI格式发送的下行控制信息。
比如，第一信息域的信息比特数量可以是1比特，该1比特的信息域的状态值等于1，表明基站发送的下行控制信息是闭环传输机制下的下行控制信息，即存在第四DCI格式；若第三DCI格式中不存在该信息域或即使存在该信息域，但该信息域的状态值等于0，则表明基站发送的下行控制信息不是闭环传输机制下的下行控制信息，即不存在第四DCI格式。
可选地，第四DCI格式中包括：
-探测参考信号(sounding reference signal，简称SRS)请求指示域，用于承载SRS请求(SRS request)指示信息，该信息域可以是0比特或1比特信息域；.
-层指示域，用于承载信道传输的空间层数的指示信息，该信息域的比特数量可以是3比特；
-PDSCH资源单元(resource element，简称RE)映射和准同位置指示域，用于承载PDSCH RE映射和准同位置指示(PDSCH RE mapping and quasi-co-location indicator)，该信息域可以是2比特信息域；
-非周期参考信号速率匹配指示域，用于承载非周期参考信号速率匹配的指示信息，该信息域的比特数量可以是x比特，x为大于0的整数。该非周期参考信号可以是CSI-RS。
-为下一代无线系统(next radio，简称NR)新增信息比特预留的信息域，用于承载其他可能的NR新增信息比特，该信息域的比特数量可以是y比特，y为大于等于0的整数。如，5G系统新引入的波束相关的一些新控制信息。
以上实施例虽然以下行数据或信号传输对应的控制信息为例描述，但上述实施例的实现原理也可适用于上行数据或信号传输对应的控制信息。在上行数据或信号传输对应的控制信息及控制信息格式中，除用于公共系统信息的控制指示信息外，用于用户专用信道的第三格式和第四格式可承载的内容以及可包含的信息域可同前所述，在此不再重复。同理，第三格式主要用于传输上述四种传输机制所共有的用户专用信道控制指示信息；第四格式用于传输闭环传输机制所特有的用户专用信道控制指示信息。
图3示出了本发明实施例提供的适合于方案二的控制信息传输流程示意图，该流程可包括如下步骤：
步骤301：控制信息的发送设备发送控制信息，该控制信息与上述几种传输机制中的一种传输机制相关联，该控制信息使用的控制信息格式可包括第三控制信息格式、第四控 制信息格式和第五控制信息格式中的一种或多种，其中，上述几种传输机制中的第一传输机制，其一部分控制信息使用第三控制信息格式，另一部分控制信息使用第四控制信息格式。该步骤中，发送设备发送控制信息的方式可参见前述描述。
步骤302：控制信息的接收设备接收发送设备发送的控制信息，并进一步根据接收的控制信息进行相应处理。
该步骤中，接收设备可根据第三控制信息格式中的信息域判断控制信息对应的传输机制类型，进而采用给传输机制进行数据传输。
在接收设备侧，接收设备可接收发送设备按照上述方法发送的控制信息，根据接收到的第三控制信息格式中的相关信息域确定该控制信息所关联的传输机制。比如，在下行控制信息的传输中，终端可根据第三DCI格式中的第一信息域的状态值确定该下行控制信息所关联的传输机制的类型，终端也可以根据第三DCI格式中的其他信息域的状态值确定该下行控制信息所关联的传输机制的类型。
一种下行数据传输对应的下行控制信息传输的场景中，在t1时刻，基站确定采用发送分集的传输机制，则使用第三DCI格式将该传输机制的下行控制信息发送给终端(其中第三DCI格式中的第一信息域的取值为0，指示出不存在第四DCI格式)；在t2时刻，基站确定采用闭环传输，则使用第三DCI格式和第四DCI格式将该传输机制的下行控制信息发送给终端(其中第三DCI格式中的第一信息域的状态值等于1，指示存在第四DCI格式)。终端侧，如果接收到的第三DCI格式中包含的第一信息域中的指示信息指示不存在第四DCI格式，则不再盲检第四DCI格式，否则，需要盲检第四DCI格式以获得闭环传输的下行控制信息。
通过以上对方案二的实施例的描述可以看出，控制信息的发送设备所发送的控制信息与至少两种传输机制中的一种传输机制相关联，并且该控制信息中包含用于指示传输机制类型的信息，这样，可使控制信息的接收设备根据接收到的控制信息确定出对应的传输机制，进而当控制信息的发送设备需要切换传输机制时，可发送相应的控制信息，以使接收设备根据该控制信息切换到相应的传输机制。
方案三
本发明方案三中，针对不同类型的控制信道使用不同类型的控制信息格式发送控制信息。其中，第一控制信道对应P个第一类控制信息格式，第二控制信道对应Q个第二类控制信息格式，P和Q均为大于等于1的整数。
两类控制信息格式在以下方面中的至少一方面有所区别：
-两类控制信息格式对应的控制信息格式数量不同，即P和Q的取值不相等。
-两类控制信息格式对应的最大比特数不同。其中，第一类控制信息格式的最大比特数是指第一类控制信息格式中具有最大比特数的控制信息格式的大小，第二类控制信息格式的最大比特数是指第二类控制信息格式中具有最大比特数的控制信息格式的大小。可选地，第一类控制信息格式的最大比特数小于第二类控制信息格式的最大比特数。
-两类控制信息格式对应的最小比特数不同。其中，第一类控制信息格式的最小比特数是指第一类控制信息格式中具有最小比特数的控制信息格式的大小，第二类控制信息格式的最小比特数是指第二类控制信息格式中具有最小比特数的控制信息格式的大小。可选地，第一类控制信息格式的最小比特数小于第二类控制信息格式的最小比特数。
可选地，在下行控制信息的传输中，第一控制信道可包括物理下行控制信道(physical  downlink control channel，简称PDCCH)，第二控制信道可包括增强物理下行控制信道(enhanced-physical downlink control channel，简称e-PDCCH)。第一控制信道对应的第一类DCI格式主要为一些信息比特数较小的控制信息指示格式。如DCI格式1C，DCI格式2A等。第二控制信道对应的第二类DCI格式主要为一些信息比特数较大的控制信息指示格式，如DCI格式2，DCI格式2D等。
可选地，使用上述第一类控制信息格式或第二类控制信息格式发送的控制信息为对应于用户专用信道的数据传输的控制信息。在下行数据传输对应的下行控制信息传输中，所述用户专用信道可以为PDSCH或PUSCH，也可以为其他用户专用的信道，这里不做限定。
可选地，第一类控制信息格式用于第一传输机制的控制信息指示，第二类控制信息格式用于第二传输机制的控制信息指示。其中，以传输机制包括发射分集、开环传输、闭环传输为例，此处的第一传输机制包括发射分集和/或开环传输，或者，第二传输机制包括开环传输和/或闭环传输。例如，第一传输机制和第二传输机制的组合情况可包括以下中的一种：
第一传输机制为发射分集，第二传输机制可包括开环传输、闭环传输中的一种或多种；
第一传输机制为开环传输，第二传输机制可包括发射分集、闭环传输中的一种或多种；
第二传输机制为开环传输，第一传输机制可包括发射分集、闭环传输中的一种或多种；
第二传输机制为闭环传输，第一传输机制可包括发射分集、开环传输中的一种或多种。
所述传输机制为用户专用信道，如PDSCH或PUSCH的数据传输机制，也可以为其他信道或信号(如增强型下行控制信道)的数据传输所采用的传输机制，这里不做限定。
可选地，第一控制信道对应P个第一类控制信息格式，与第二控制信道对应的Q个第二类控制信息格式中可以有部分相同，比如，上述P个第一类控制信息格式中的T个控制信息格式，与上述Q个第二类控制信息格式中的T个控制信息格式相同，T为大于等于1的整数，T小于等于P且小于等于Q。
图4示出了本发明实施例提供的适合于方案三的控制信息(如下行控制信息或上行控制信息)传输流程示意图，该流程可包括如下步骤：
步骤401：控制信息的发送设备根据发送控制信息的控制信道类型，使用与该控制信道类型对应的控制信息格式发送所述控制信息，其中，第一控制信道对应P个第一类控制信息格式，第二控制信道对应Q个第二类控制信息格式。
步骤402：控制信息的接收设备接收发送设备发送的控制信息，并进一步根据接收的控制信息进行相应处理。
该步骤中，以下行控制信息传输为例，终端可根据第一类DCI格式对第一控制信道进行盲检，获得通过第一控制信道发送的下行控制信息；终端可根据第二类DCI格式对第二控制信道进行盲检，获得通过第二控制信道发送的下行控制信息。
本发明的上述实施例中，控制信息的发送设备根据发送控制信息的控制信道类型，使用与该控制信道类型对应的控制信息格式发送该控制信息，其中，第一控制信道对应P个第一类控制信息格式，第二控制信道对应Q个第二类控制信息格式，两类控制信息格式分别对应的控制信息格式数量、控制信息格式的最大比特数、控制信息格式的最小比特数中的至少一个不同，这样，可以对应不同类型的控制信道使用不同类型的控制信息格式发送控制信息。由于两类控制信息格式分别对应的控制信息格式数量、控制信息格式的最大比特数、控制信息格式的最小比特数中的至少一个不同，因此实现了基于控制信道的类型使 用与该类型适配的控制信息格式进行控制信息的发送，从而提高了控制信息传输的性能。
基于相同的技术构思，本发明实施例还提供了相应的装置。
参见图5，为本发明实施例提供的控制信息发送装置。可实现前述方案一或方案二提供的控制信息发送流程。如图5所示，该装置可包括发送模块501，发送模块501用于发送控制信息，所述控制信息与至少两种传输机制中的一种传输机制相关联，所述控制信息中包含用于指示传输机制类型的信息。发送模块501发送控制信息的具体方法可参见前述实施例，在此不再详述。
