Description

传输信号的方法、网络设备和终端设备 技术领域
本发明实施例涉及通信技术领域，特别涉及一种传输信号的方法、网络设备和终端设备。
背景技术
无线通信中，在使用低频载波的场景下，无线信号的路径损耗比较小，每个天线端口形成的波束是宽波束，因此可以覆盖整个小区的用户，例如，如图1所示，网络设备的广播信道，系统消息，寻呼等可以通过宽波束进行发射可以很好的覆盖到终端设备1和终端设备2。
但是高频的场景下，如图2所示，无线信号的路径损耗增大，如果仍然用宽波束发射，则小区的覆盖非常小，无法覆盖到距离较远的终端设备3和终端设备4。
在高频下，天线间距可以变小，因此单位面积可容纳的天线数增多，因此可以利用大规模多输入多输出(massive MIMO)的波束成形(beamforming)技术形成很高的天线增益来弥补路径损耗。Massive MIMO的天线会达到很多，甚至上百根，在形成大的天线增益的同时，形成的波束(beam)的宽度很窄，一个窄波束只能覆盖部分区域，无法覆盖到小区中的所有用户。例如如图3所示，对于波束B2，只能覆盖到终端设备5，而终端设备6无法被波束B2覆盖。
在高频多波束发送的场景下，为了为小区内的用户服务，不同的波束可能需要分时为小区内的用户服务，各个波束下需要广播信道，同步信道，控制信道等公共信道覆盖到小区所有的用户，以使小区内的用户获得同步和必要的系统消息，从而接入小区。
按照现有发送控制信道的发送方法发送波束成形的控制信道，例如，以现有的控制信道为物理下行控制信道(Physical Downlink Control Channel，PDCCH)，波束成形的控制信道为波束成形的(beamformed)PDCCH为例而言，那么在一个子帧中可能同时出现广覆盖的PDCCH用于为老终端设备服务，和beamformed PDCCH用于支持覆盖增强的终端设备服务。广覆盖的PDCCH使用同样是广覆盖的公共参考信号(Cell-specific Reference Signals， CRS)进行解调，而beamformed PDCCH却不能使用现有的CRS进行解调，需要使用采用相同beamforming的参考信号进行解调。因此，当PDCCH采用beamforming后，如果没有对应的beamformed参考信号，UE无法正确的接收beamformed PDCCH。
因此，如何传输波束成形的控制信道及其参考信号称为亟待解决的问题。
发明内容
本发明实施例提供了一种传输信号的方法、网络设备和终端设备，该方法能够实现传输波束成形的控制信道及其参考信号。
第一方面提供了一种传输信号的方法，该方法包括：
确定第一时频资源，该第一时频资源为多个候选资源中的第一候选资源；
按照预设规则，根据该第一时频资源获得第二时频资源和第三时频资源，该第三时频资源包括该第一时频资源中预定义位置中的至少一个资源元素RE，该第二时频资源包括该第一频资源中除该第三时频资源外的资源，该预设规则指示该预定义位置，其中，该第二时频资源用于承载波束成形的控制信道，该第三时频资源用于承载该波束成形的控制信道的参考信号；
通过该第二时频资源和该第三时频资源分别向终端设备传输该波束成形的控制信道和该波束成形的控制信道的参考信号。
因此，本发明实施例通过确定出承载波束成形的控制信道及其参考信号的资源，实现了传输波束成形的控制信道及其参考信号。使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
需要说明的是，本发明实施例中涉及的术语“候选资源”定义如下：
在一个时频资源集合中，可以划分成多个时频资源子集，候选资源即为按照一定的规则选择的一个或多个时频资源子集组成的资源。
例如，以长期演进(Long Term Evolution，LTE)系统为例，该一个时 频资源集合可以为一个子帧中的前1-3个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号对应的时频资源，该时频资源子集可以为控制信道单元(Channel Control Element，CCE)或增强控制信道单元(Enhanced Channel Control Element，ECCE)，候选资源即为按照一定规则选择的一个或多个子集。例如，候选资源包括1个CCE、2个CCE、4个CCE或8个CCE，对应的聚合级别分别为1、2、4或8，
例如，网络设备可以按照现有的LTE中确定PDCCH资源的方法确定第一时频资源。
可选地，该确定第一时频资源，包括：
确定聚合级别，该聚合级别用于表示该候选资源的大小；
从与该聚合级别对应的该多个候选资源的集合中选择一个候选资源资作为该第一时频资源。
具体地，网络设备可以首先确定聚合级别，该聚合级别用于表示该候选资源的大小；例如，网络设备可以首先确定PDCCH format(格式)，一个PDCCH format对应一定的聚合级别，聚合级别对应承载PDCCH的CCE个数，该CCE个数对应该PDCCH format的候选资源的大小；
然后从与该聚合级别对应的该多个候选资源的集合中选择一个候选资源资作为该第一时频资源。
应理解，聚合级别可以包括4和8，或者1、2、4和8等，聚合级别的详细说明可以参见现有标准的定义，此处不再赘述。
应理解，第一时频资源可以包括多个(该个数与聚合级别对应)资源单元(Resource Element，RE)集合，多个RE集合中的每个RE集合包括同一固定个数的RE。
例如，以LTE为例，一个RE集合为一个控制信道单元CCE，一个PDCCH由至少一个CCE承载，承载一个PDCCH的CCE的个数由聚合级别确定，例如CCE的个数可以是1、2、4或8。一个CCE包括9个资源单元组(resource element group，REG)，一个REG包括4个RE。即一个RE集合可以包括36个RE。这里仅以LTE为例说明，在不同的系统中，一个RE集合可以包括其他个数的RE，本发明实施例并不限于此。
在LTE系统中，分别针对聚合级别1、2、4和8，第一时频资源可以由子帧的前1-3个正交频分多址OFDM符号中的1控制信道单元CCE、连续 的2个CCE、连续的4个CCE和连续的8个CCE聚合而成。例如，如图5所示，第一时频资源包括8个CCE，分别是CCE0至CCE7。
也就是说，这里的候选资源集合可以对应现有的承载现有的PDCCH的资源集合。
在本发明实施例中，第一时频资源可以即用于承载波束成形的PDCCH和也用于承载该波束成形的PDCCH的参考信号。
应理解，本发明实施例中的多个候选资源可以包括所有的聚合级别对应的候选资源，也可以包括某一个聚合级别对应的候选资源，本发明实施例并不对此做限定。
应理解，上文中，按照现有的LTE中确定PDCCH资源的方法确定第一时频资源，并描述了第一时频资源可以包括多个CCE的例子。本发明实施例中第一时频资源还可以是网络设备可以按照现有的LTE中确定增强物理下行控制信道(Enhanced Physical Downlink Control Channel，EPDCCH)资源的方法确定第一时频资源。EPDCCH由至少一个ECCE承载，承载一个EPDCCH的ECCE的个数由EPDCCH format确定，每个EPDCCH format对应一定的聚合级别，集合级别对应一定数目的ECCE。EPDCCH候选资源集合可以对应某一个EPDCCH format对应的包含一定ECCE个数的资源集合。每个ECCE可以包含4或者8个EREG，EPDCCH format对应的聚合级别包括1、2、4、8、16、32，即对应的第一时频资源可以包括1、2、4、8、16、32个ECCE。
应理解，本发明实施例中的预设规则可以是系统预设好的规则，换句话说，预设规则可以是网络设备和终端设备预先约定好的规则，在第一资源确定后，网络设备和终端设备即可以根据该预设规则获取到第二资源和第三资源。
应理解，预设规则可以是网络设备和终端设备预先约定好的规则，在第一资源确定后，网络设备和终端设备即可以根据该预设规则获取到第二资源和第三资源。预设规则还可以是网络设备通过信令通知终端设备的，即网络设备通过预先发送消息与终端设备约定该预设规则。
相应地，作为另一实施例，在410之前，该方法还可以包括向该终端设备发送指示消息，该指示消息指示该预定义位置。
例如，该指示消息，可以为无线资源控制(Radio Resource Control，RRC) 信令消息，本发明实施并不限于此。
可选地，该第一时频资源包括多个资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE，该第三时频资源包括该多个RE集合中的每一个RE集合中的预设位置中的RE。
可选地，该第一时频资源包括多个资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE，该第三时频资源包括该多个RE集合中的至少一个RE集合中的所有的RE。
第二方面，提供了一种传输信号的方法，该方法包括：
检测第一时频资源，该第一时频资源为多个候选资源中的第一候选资源；
按照预设规则，根据该第一时频资源获得第二时频资源和第三时频资源，该第三时频资源包括该第一时频资源中预定义位置中的至少一个资源元素RE，该第二时频资源包括该第一频资源中除该第三时频资源外的资源，该预设规则指示该预定义位置，其中，该第二时频资源用于承载波束成形的控制信道，该第三时频资源用于承载该波束成形的控制信道的参考信号；
根据该第三时频资源中承载的该波束成形的控制信道的参考信号解调该第二时频资源中承载的波束成形的控制信道。
因此，本发明实施例通过确定出承载波束成形的控制信道及其参考信号的资源，实现了传输波束成形的控制信道及其参考信号。使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
应理解，该第二方面与上述第一方面对应，第一方面的执行主体为网络设备，第二方面中的执行主体可以为终端设备，终端侧的方法的相应特征可以参见上述第一方面的描述，因此，为了简洁，适当省略详细描述。
可选地，该第一时频资源包括多个资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE，该第三时频资源包括该多个RE集合中的每一个RE集合中的预设位置中的RE。
可选地，该第一时频资源包括、多个资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE，该第三时频资源包括该多个RE集合中的至少一个RE集合中的所有的RE。
可选地，，在该检测第一时频资源，之前，该方法还包括：
接收指示消息，该指示消息指示该预设规则。
第三方面，提供了一种传输信号的方法，包括：
确定第一时频资源，该第一时频资源为多个候选资源中的第一候选资源，该第一时频资源用于承载波束成形的控制信道；
确定第二时频资源，该第二时频资源为所述多个候选资源中的第二候选资源，或所述第二时频资源为向终端设备配置的所述多个候选资源外的资源，该第二时频资源用于承载该波束成形的控制信道的参考信号；
通过该第一时频资源和该第二时频资源分别向终端设备传输该波束成形的控制信道和该波束成形的控制信道的参考信号。
因此，本发明实施例通过确定出承载波束成形的控制信道及其参考信号的资源，实现了传输波束成形的控制信道及其参考信号。使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
需要说明的是，本发明实施例中涉及的术语“候选资源”定义如下：
在一个时频资源集合中，可以划分成多个时频资源子集，候选资源即为按照一定的规则选择的一个或多个时频资源子集组成的资源。
例如，以LTE系统为例，该一个时频资源集合可以为一个子帧中的前1-3个OFDM符号对应的时频资源，该时频资源子集可以为CCE或ECCE，候选资源即为按照一定规则选择的一个或多个子集。其中，候选资源包括1个CCE、2个CCE、4个CCE或8个CCE，对应的聚合级别分别为1、2、4或8，
例如，网络设备可以按照现有的LTE中确定PDCCH资源的方法确定第一时频资源。
具体地，网络设备可以首先确定聚合级别，该聚合级别用于表示该候选资源的大小；例如，网络设备可以首先确定PDCCH format(格式)，一个PDCCH format对应一定的聚合级别，聚合级别对应承载PDCCH的CCE个数，该CCE个数对应该PDCCH format的候选资源的大小；
然后从与该聚合级别对应的该多个候选资源的集合中选择一个候选资源资作为该第一时频资源。
应理解，聚合级别可以包括4和8，或者1、2、4和8等，聚合级别的详细说明可以参见现有标准的定义，此处不再赘述。
应理解，第一时频资源可以包括多个(该个数与聚合级别对应)资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE。
例如，以LTE为例，一个RE集合为一个控制信道单元CCE，一个PDCCH由至少一个CCE承载，承载一个PDCCH的CCE的个数由聚合级别确定，例如CCE的个数可以是1、2、4或8。一个CCE包括9个资源单元组(resource element group，REG)，一个REG包括4个RE。即一个RE集合可以包括36个RE。这里仅以LTE为例说明，在不同的系统中，一个RE集合可以包括其他个数的RE，本发明实施例并不限于此。

也就是说，这里的候选资源集合可以对应现有的承载现有的PDCCH的资源集合。
在本发明实施例中，第一时频资源可以用于承载波束成形的PDCCH。
应理解，本发明实施例中的多个候选资源可以包括所有的聚合级别对应的候选资源，也可以包括某一个聚合级别对应的候选资源，本发明实施例并不对此做限定。
应理解，上文中，按照现有的LTE中确定PDCCH资源的方法确定第一时频资源，并描述了第一时频资源可以包括多个CCE的例子。本发明实施例中第一时频资源还可以是网络设备可以按照现有的LTE中确定EPDCCH资源的方法确定第一时频资源。EPDCCH由至少一个ECCE承载，承载一个EPDCCH的ECCE的个数由EPDCCH format确定，每个EPDCCH format对应一定的聚合级别，集合级别对应一定数目的ECCE。EPDCCH候选资源集合可以对应某一个EPDCCH format对应的包含一定ECCE个数的资源集合。每个ECCE可以包含4或者8个EREG，EPDCCH format对应的聚合级别包括1、2、4、8、16、32，即对应的第一时频资源可以包括1、2、4、8、16、32个ECCE。
具体地，该第二时频资源为该第一时频资源外的资源，该第二时频资源用于承载该波束成形的控制信道的参考信号。
应理解，本发明实施例中的第二时频资源具有多种可行的方式，下面分别针对第二时频资源为第二候选资源和第二时频资源为向终端设备配置的该多个候选资源外的资源进行详细描述。
在该第二时频资源为该多个候选资源中的第二候选资源时，
该第二时频资源可以为该多个候选资源中的预定义的该第二候选资源。
也就是说，该第二时频资源为预定义的资源，该预定义的资源为多个候选资源中的一个候选资源即第二候选资源。
也即，该第二资源为预先定义的资源，也即系统预先定义的资源，或者说网络设备和终端设备预先约定好的资源。网络设备和终端设备都预先知道该第二资源的位置，且该第二资源承载波束成形的控制信道的参考信号。
应理解，第二时频资源可以与第一时频资源的大小(例如聚合级别)相同，也可以不同，本发明实施例并不对此做限定。
例如，第二时频资源可以与第一时频资源的大小(例如聚合级别)相同，也即第二时频资源为与第一时频资源对应的多个候选资源集合中除第一时频资源外的一个候选资源。例如在LTE系统中，第一时频资源和第二时频资源的聚合级别都为1、2、4或8等。
再例如，第二时频资源的大小于第二时频资源的大小不同，也即第二时频资源为另一候选资源集合中的一个候选资源。例如，在LTE系统中，第一时频资源的聚合级别为2，第二候选资源的聚合级别为4等。
另外，在该第二时频资源为该多个候选资源中的第二候选资源时，
该第二时频资源为向终端设备配置的该第二候选资源。
例如，网络设备可以向该终端设备发送用于配置第二资源为第二候选候选资源的消息。例如，该消息可以为RRC信令消息，但本发明实施例并不限于此。
再者，在该第二时频资源为该多个候选资源中的第二候选资源时，
该网络设备可以根据预设的与第一时频资源的映射关系，确定该第二候选时频资源。
一种情况，该第二候选时频资源可以为该多个候选资源的中与该第一时频资源大小相等的候选资源中的一个候选资源。
例如，网络设备可以根据预设的与第一时频资源的映射关系，确定第二时频资源，该第二时频资源为该大小相等的候选资源中除该第一时频资源外的另一个候选资源。
例如，该映射关系指示第二时频资源可以是与第一时频资源相邻的候选资源，或者与第一时频资源相邻固定间隔的时频资源等。
应理解，该映射关系可以为网络设备和终端设备预先约定好的，例如，可以是网络设备预先发送给终端设备的，本发明实施例并不对此做限定。
另一种情况，该第二候选时频资源为该多个候选资源的中指定大小的候选资源中不与该第一时频资源重叠的一个候选资源。
例如，该指定大小可以为聚合级别为1、2、4或8等，其中，该指定大小可以与第一时频资源相同，也可以不同，本发明实施例并不对此做限定。
例如，该指定大小可以为聚合级别为4，第二时频资源可以是为聚合级别为4的多个候选资源中不与第一时频资源重合候选资源中编号最小或最大的一个候选资源。本发明实施例并不限于此。但应理解，网络设备和终端设备中确定的第二时频资源的规则必须一致。例如，网络设备和终端设备都约定第二时频资源为指定大小的多个候选资源的集合中不与该第一时频资源重叠的编号最小的一个候选资源。
在该第二时频资源为向终端设备配置的该多个候选资源外的资源时；
该第二时频资源包括网络设备向该终端设备配置的该第一时频资源外的资源。
例如，该第二时频资源包括除公共参考信号CRS外的其他参考信号对应的时频资源，或者该第二时频资源包括数据信道对应的时频资源。
具体而言，网络设备可以向该终端设备发送用于配置的指示消息，该指示消息指示该第二时频资源的位置。例如，该指示消息可以为RRC信令消息，但本发明实施例并不限于此。
例如，在LTE中，第二时频资源可以为子帧中第4至第14个OFDM符号中的时频资源。
例如，该第二时频资源可以包括该该子帧中第4至第14个OFDM符号中对应PDSCH的资源。
具体地，第二时频资源可以包括为该用户设备配置的零功率用户状态信息参考信zero-power CSI-RS资源中的至少一个RE。
或者，该第三时频资源可以包括该该子帧中第4至第14个OFDM符号中为该用户设备配置的非零功率用户状态信息参考信Non zero-power CSI-RS资源中的至少一个RE。
因此，本发明实施例中在现有的承载控制信道的第一时频资源中承载波束成形的控制信道，在另外的资源(第二时频资源)中承载该波束成形的控制信道的参考信号，实现了波束成形的控制信道及其参考信号的发送，使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
第四方面，提供了一种传输信号的方法，包括：
检测第一时频资源，该第一时频资源为多个候选资源中的第一候选资源，该第一时频资源用于承载波束成形的控制信道；
检测第二时频资源，该第二时频资源为该多个候选资源中的第二候选资源，或该第二时频资源为向终端设备配置的该多个候选资源外的资源，该第二时频资源用于承载该波束成形的控制信道的参考信号；
根据该第二时频资源中承载的该波束成形的控制信道的参考信号解调该第一时频资源中承载的波束成形的控制信道。
因此，本发明实施例通过确定出承载波束成形的控制信道及其参考信号的资源，实现了传输波束成形的控制信道及其参考信号。使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
应理解，该第四方面与上述第三方面对应，第三方面的执行主体为网络设备，第四方面中的执行主体可以为终端设备，终端侧的方法的相应特征可以参见上述第三方面的描述，因此，为了简洁，适当省略详细描述。

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的一部分实施例，而不是全部实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系 统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)或全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统等。本发明实施例仅以LTE，举例进行详细说明，但并不限于此。
还应理解，本发明实施例中的网络设备可以是GSM系统或码分多址(Code Division Multiple Access，CDMA)系统中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备、未来5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
终端设备可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、未来5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的终端设备等。
需要说明的是，本发明实施例中涉及的术语“候选资源”定义如下：
在一个时频资源集合中，可以划分成多个时频资源子集，候选资源即为按照一定的规则选择的一个或多个时频资源子集组成的资源。
例如，以LTE系统为例，该一个时频资源集合可以为一个子帧中的前1-3个OFDM符号对应的时频资源，该时频资源子集可以为CCE或ECCE，候选资源即为按照一定规则选择的一个或多个子集。其中，候选资源包括1个CCE、2个CCE、4个CCE或8个CCE，对应的聚合级别分别为1、2、4或8，
图4是根据本发明一个实施例的信号的发送方法的示意性流程图。如图 4所示的方法可以应用于上述各种通信系统中，图4中仅以LTE系统，控制信道为PDCCH为例进行详细说明，但本发明实施例并不限于此，换句话说，本发明实施例中的各种术语在不同的系统中可以具有不同的名称，本发明实施例并不对此做限定。本发明实施例中的通信系统中包括网络设备和终端设备。图4所示的方法400包括：
410，网络设备确定第一时频资源。
具体地，网络设备确定第一时频资源。该第一时频资源为多个候选资源中的第一候选资源。
换句话说，第一时频资源为多个候选资源的集合中的一个候选资源。
例如，网络设备可以按照现有的LTE中确定PDCCH资源的方法确定第一时频资源。
具体地，网络设备可以首先确定聚合级别，该聚合级别用于表示该候选资源的大小；例如，网络设备可以首先确定PDCCH format(格式)，一个PDCCH format对应一定的聚合级别，聚合级别对应承载PDCCH的CCE个数，该CCE个数对应该PDCCH format的候选资源的大小；
然后从与该聚合级别对应的该多个候选资源的集合中选择一个候选资源资作为该第一时频资源。
应理解，聚合级别可以包括4和8，或者1、2、4和8等，聚合级别的详细说明可以参见现有标准的定义，此处不再赘述。
应理解，第一时频资源可以包括多个(该个数与聚合级别对应)资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE。
例如，以LTE为例，一个RE集合为一个控制信道单元CCE，一个PDCCH由至少一个CCE承载，承载一个PDCCH的CCE的个数由聚合级别确定，例如CCE的个数可以是1、2、4或8。一个CCE包括9个资源单元组(Resource Element Group，REG)，一个REG包括4个RE。即一个RE集合可以包括36个RE。这里仅以LTE为例说明，在不同的系统中，一个RE集合可以包括其他个数的RE，本发明实施例并不限于此。
在LTE系统中，分别针对聚合级别1、2、4和8，第一时频资源可以由子帧的前1-3个正交频分多址OFDM符号中的1控制信道单元CCE、连续的2个CCE、连续的4个CCE和连续的8个CCE聚合而成。例如，如图5 所示，第一时频资源包括8个CCE，分别是CCE0至CCE7。
也就是说，这里的候选资源集合可以对应现有的承载现有的PDCCH的资源集合。
在本发明实施例中，第一时频资源可以即用于承载波束成形的PDCCH和也用于承载该波束成形的PDCCH的参考信号。
应理解，本发明实施例中的多个候选资源可以包括所有的聚合级别对应的候选资源，也可以包括某一个聚合级别对应的候选资源，本发明实施例并不对此做限定。
应理解，上文中，按照现有的LTE中确定PDCCH资源的方法确定第一时频资源，并描述了第一时频资源可以包括多个CCE的例子。本发明实施例中第一时频资源还可以是网络设备可以按照现有的LTE中确定EPDCCH资源的方法确定第一时频资源。EPDCCH由至少一个ECCE承载，承载一个EPDCCH的ECCE的个数由EPDCCH format确定，每个EPDCCH format对应一定的聚合级别，集合级别对应一定数目的ECCE。EPDCCH候选资源集合可以对应某一个EPDCCH format对应的包含一定ECCE个数的资源集合。每个ECCE可以包含4或者8个EREG，EPDCCH format对应的聚合级别包括1、2、4、8、16、32，即对应的第一时频资源可以包括1、2、4、8、16、32个ECCE。
因此，本发明实施例通过按照现有的方法确定第一资源用于后续承载波束成形的控制信道和参考信号，由于与现有的方式相同，因此，本发明实施例的波束成形的控制信道及其参考信号的发送对传统终端设备的兼容性没有影响或者影响很小。
420，网络设备获得第二时频资源和第三时频资源。
具体地，网络设备按照预设规则，根据该第一时频资源获得第二时频资源和第三时频资源，该第三时频资源包括该第一时频资源中预定义位置中的至少一个资源元素RE，该第二时频资源包括该第一频资源中除该第三时频资源外的资源，该预设规则指示该预定义位置，其中，该第二时频资源用于承载波束成形的控制信道，该第三时频资源用于承载该波束成形的控制信道的参考信号；
换句话说，本发明实施例中在现有的承载控制信道的第一时频资源中既承载承载波束成形的控制信道也承载该波束成形的控制信道的参考信号，实 现了波束成形的控制信道及其参考信号的发送，使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
应理解，本发明实施例中的预设规则可以是系统预设好的规则，换句话说，预设规则可以是网络设备和终端设备预先约定好的规则，在第一资源确定后，网络设备和终端设备即可以根据该预设规则获取到第二资源和第三资源。
具体而言，该第三时频资源可以包括该第一时频资源中的至少一个资源元素RE，该第二时频资源包括该第一频资源中除该第三时频资源外的资源。
具体地，该第三时频资源可以包括上述多个RE集合中的至少一个RE集合中的一个RE。
例如，第三时频资源可以仅包括一个RE集合中的一个RE，也可以包括多个RE集合中的RE，其中一个RE集合中仅一个RE属于第三时频资源；第三时频资源也可以包括每一个RE集合中个一个RE。
再例如，该第三时频资源可以上述多个RE集合中的每一个RE集合的预设位置中的RE。
例如，以LTE系统为例，该预设位置可以为每个CCE中的每个REG中的第n个RE,这里n可以为1、2、3或4。例如，如图6所示，第一时频资源包括8个CCE，第三时频资源可以包括每一个CCE中的每个REG中的第2个RE(例如，REG0中的RE1)。图3中为了描述简便，这里以CCE3为例显示了第一时频资源包括的RE。其他的CCE中对应位置中的RE均属于第三时频资源，图6中未示出。
应理解，图6中为了描述的方便，以该的RE集合中的预设位置相同，即都为每个REG中的第2个RE，进行了说明。但本发明实施例中的不同的RE集合中的预设位置可以相同，也可以不同，本发明实施例并不对此做限定。
可替代地，第三时频资源可以包括该多个RE集合中的至少一个RE集合中的所有的RE。
例如，第三时频资源可以仅包括一个RE集合中的所有RE，也可以包括多个RE集合中的所有RE。
例如，第一时频资源包括多个CCE时，第三时频资源可以包括多个CCE中的至少一个CCE中的全部RE。
应理解，第三时频资源可以包括多个CCE中的至少一个CCE中的全部RE，但第三时频资源必须小于第一时频资源，第一时频资源中除第三时频资源外的资源为第二时频资源。类似的，本发明实施例中的第二资源也必须小于第一时频资源，第一时频资源中除第二时频资源外的资源为第三时频资源。
例如，如图7所示，第一时频资源包括8个CCE，第三时频资源可以包括一个CCE，例如CCE3中的全部RE。
应理解，预设规则可以是网络设备和终端设备预先约定好的规则，在第一资源确定后，网络设备和终端设备即可以根据该预设规则获取到第二资源和第三资源。预设规则还可以是网络设备通过信令通知终端设备的，即网络设备通过预先发送消息与终端设备约定该预设规则。
相应地，作为另一实施例，在410之前，该方法还可以包括向该终端设备发送指示消息，该指示消息指示该预定义位置。
例如，该指示消息，可以为RRC信令消息，本发明实施并不限于此。
430，发送波束成形的控制信道及其参考信号。
具体地，网络设备通过该第二时频资源和该第三时频资源分别向终端设备传输该波束成形的控制信道和该波束成形的控制信道对应的参考信号RS。
终端设备进而可以根据接收到的波束成形的控制信道的参考信号对波束成形的控制信道进行解调。例如，终端设备接收搜索空间内的候选资源集合中的候选资源上的信号，在盲检测候选频资源时，例如，该候选资源可能为第一时频资源，根据预定义位置中的第三时频资源上的参考信号对第二时频资源承载的控制信道进行解调，终端设备对接收到的控制信道的信息比特进行解码，并根据自己的ID进行CRC校验，如果校验通过，则成功接收到发给自己的控制信道，即上述盲检测的候选资源即为第一时频资源。如果校验失败，则基站并未在该候选资源上发送控制信道给自己，即上述盲检测的候选资源不是第一时频资源。
因此，本发明实施例通过确定出承载波束成形的控制信道及其参考信号的资源，实现了传输波束成形的控制信道及其参考信号。使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
上文中结合图4至图7详细描述了本发明实施例的信号的发送方法。下面将结合图8描述本发明另一实施例的信号的发送方法。
应理解，图7和图8的区别在于，图7中第一时频资源即用于传输波束成形的控制信道，也用于传输该波束成形的控制信道的参考信号。而图8中在第一时候资源仅用于承载波束成形的控制信道，而波束成形的控制信道可以由另外的资源承载，例如可以是某一候选资源集合中的一个候选资源，也可以是用于承载其他信道或参考信号的资源。具体地，下面将结合图8详细描述该信号的发送方法。
图8是根据本发明一个实施例的信号的发送方法的示意性流程图。如图8所示的方法可以应用于上述各种通信系统中，图8中仅以LTE系统，控制信道为PDCCH为例进行详细说明，但本发明实施例并不限于此，换句话说，本发明实施例中的各种术语在不同的系统中可以具有不同的名称，本发明实施例并不对此做限定。本发明实施例中的通信系统中包括网络设备和终端设备。图8所示的方法800包括：
810，网络设备确定第一时频资源。
具体地，网络设备确定第一时频资源。该第一时频资源为多个候选资源中的第一候选资源，该第一时频资源用于承载波束成形的控制信道。
换句话说，第一时频资源为多个候选资源的集合中的一个候选资源。
例如，网络设备可以按照现有的LTE中确定PDCCH资源的方法确定第一时频资源。
具体地，网络设备可以首先确定聚合级别，该聚合级别用于表示该候选资源的大小；例如，网络设备可以首先确定PDCCH format(格式)，一个PDCCH format对应一定的聚合级别，聚合级别对应承载PDCCH的CCE个数，该CCE个数对应该PDCCH format的候选资源的大小；
然后从与该聚合级别对应的该多个候选资源的集合中选择一个候选资源资作为该第一时频资源。
应理解，聚合级别可以包括4和8，或者1、2、4和8等，聚合级别的详细说明可以参见现有标准的定义，此处不再赘述。
应理解，第一时频资源可以包括多个(该个数与聚合级别对应)资源单元RE集合，多个RE集合中的每个RE集合包括同一固定个数的RE。
例如，以LTE为例，一个RE集合为一个控制信道单元CCE，一个PDCCH由至少一个CCE承载，承载一个PDCCH的CCE的个数由聚合级别确定，例如CCE的个数可以是1、2、4或8。一个CCE包括9个资源单元组(resource element group，REG)，一个REG包括4个RE。即一个RE集合可以包括36个RE。这里仅以LTE为例说明，在不同的系统中，一个RE集合可以包括其他个数的RE，本发明实施例并不限于此。
在LTE系统中，分别针对聚合级别1、2、4和8，第一时频资源可以由子帧的前1-3个正交频分多址OFDM符号中的1控制信道单元CCE、连续的2个CCE、连续的4个CCE和连续的8个CCE聚合而成。例如，如图5所示，第一时频资源包括8个CCE，分别是CCE0至CCE7。
也就是说，这里的候选资源集合可以对应现有的承载现有的PDCCH的资源集合。
在本发明实施例中，第一时频资源可以用于承载波束成形的PDCCH。
应理解，本发明实施例中的多个候选资源可以包括所有的聚合级别对应的候选资源，也可以包括某一个聚合级别对应的候选资源，本发明实施例并不对此做限定。
应理解，上文中，按照现有的LTE中确定PDCCH资源的方法确定第一时频资源，并描述了第一时频资源可以包括多个CCE的例子。本发明实施例中第一时频资源还可以是网络设备可以按照现有的LTE中确定EPDCCH资源的方法确定第一时频资源。EPDCCH由至少一个ECCE承载，承载一个EPDCCH的ECCE的个数由EPDCCH format确定，每个EPDCCH format对应一定的聚合级别，集合级别对应一定数目的ECCE。EPDCCH候选资源集合可以对应某一个EPDCCH format对应的包含一定ECCE个数的资源集合。每个ECCE可以包含4或者8个EREG，EPDCCH format对应的聚合级别包 括1、2、4、8、16、32，即对应的第一时频资源可以包括1、2、4、8、16、32个ECCE。
因此，本发明实施例通过按照现有的方法确定第一资源用于后续承载波束成形的控制信道，由于与现有的方式相同，因此，本发明实施例的波束成形的控制信道的发送对传统终端设备的兼容性没有影响或者影响很小。
820，网络设备确定第二时频资源。
具体地，该第二时频资源为该多个候选资源中的第二候选资源，或该第二时频资源为向终端设备配置的该多个候选资源外的资源，该第二时频资源用于承载该波束成形的控制信道的参考信号。
换句话说，该第二时频资源可以为该第一时频资源和第三时频资源外的资源，该第三时频资源包括除该波束成形的控制信道外的其他控制信道的参考信号对应的时频资源，其中，该其他控制信道的波束与该波束成形的控制信道的波束不同。
下面分别针对第二时频资源为第二候选资源和第二时频资源为向终端设备配置的该多个候选资源外的资源进行详细描述。
在该第二时频资源为该多个候选资源中的第二候选资源时，
该第二时频资源可以为该多个候选资源中的预定义的该第二候选资源。
也就是说，该第二时频资源为预定义的资源，该预定义的资源为多个候选资源中的一个候选资源即第二候选资源。
也即，该第二资源为预先定义的资源，也即系统预先定义的资源，或者说网络设备和终端设备预先约定好的资源。网络设备和终端设备都预先知道该第二资源的位置，且该第二资源承载波束成形的控制信道的参考信号。
应理解，第二时频资源可以与第一时频资源的大小(例如聚合级别)相同，也可以不同，本发明实施例并不对此做限定。
例如，第二时频资源可以与第一时频资源的大小(例如聚合级别)相同，也即第二时频资源为与第一时频资源对应的多个候选资源集合中除第一时频资源外的一个候选资源。例如在LTE系统中，第一时频资源和第二时频资源的聚合级别都为1、2、4或8等。
再例如，第二时频资源的大小于第二时频资源的大小不同，也即第二时频资源为另一候选资源集合中的一个候选资源。例如，在LTE系统中，第一时频资源的聚合级别为2，第二候选资源的聚合级别为4等。
另外，在该第二时频资源为该多个候选资源中的第二候选资源时，
该第二时频资源为向终端设备配置的该第二候选资源。
例如，网络设备可以向该终端设备发送用于配置第二资源为第二候选候选资源的消息。例如，该消息可以为RRC信令消息，但本发明实施例并不限于此。
再者，在该第二时频资源为该多个候选资源中的第二候选资源时，
该网络设备可以根据预设的与第一时频资源的映射关系，确定该第二候选时频资源。
一种情况，该第二候选时频资源可以为该多个候选资源的中与该第一时频资源大小相等的候选资源中的一个候选资源。
例如，网络设备可以根据预设的与第一时频资源的映射关系，确定第二时频资源，该第二时频资源为该大小相等的候选资源中除该第一时频资源外的另一个候选资源。
例如，该映射关系指示第二时频资源可以是与第一时频资源相邻的候选资源，或者与第一时频资源相邻固定间隔的时频资源等。
例如，如图9所示，候选资源集合中包括10个候选资源，分别为候选资源1至候选资源10。假若该映射关系指示第二时频资源可以是与第一时频资源右相邻的第一个候选资源，那么当第一时频资源为候选资源5时，那么第二时频资源资源即为候选资源6。
再例如，假若该映射关系指示第二时频资源可以是与第一时频资源右间隔为2的候选资源，那么当第一时频资源为候选资源5时，那么第二时频资源资源即为与候选资源5右间隔为2的候选资源8。
应注意，在实际应用中候选不同的候选资源可以有重合，相邻的候选资源可以有间隔，为了描述的简便图9中仅是示意性的描述了各个候选资源的情形，但本发明实施例并不对此做限定。
应理解，该映射关系可以为网络设备和终端设备预先约定好的，例如，可以是网络设备预先发送给终端设备的，本发明实施例并不对此做限定。
另一种情况，该第二候选时频资源为该多个候选资源的中指定大小的候选资源中不与该第一时频资源重叠的一个候选资源。
例如，该指定大小可以为聚合级别为1、2、4或8等，其中，该指定大小可以与第一时频资源相同，也可以不同，本发明实施例并不对此做限定。
例如，该指定大小可以为聚合级别为4，第二时频资源可以是为聚合级别为4的多个候选资源中不与第一时频资源重合候选资源中编号最小或最大的一个候选资源。本发明实施例并不限于此。但应理解，网络设备和终端设备中确定的第二时频资源的规则必须一致。例如，网络设备和终端设备都约定第二时频资源为指定大小的多个候选资源的集合中不与该第一时频资源重叠的编号最小的一个候选资源。
在该第二时频资源为向终端设备配置的该多个候选资源外的资源时；
该第二时频资源包括网络设备向该终端设备配置的该第一时频资源外的资源。
例如，该第二时频资源包括除公共参考信号CRS外的其他参考信号对应的时频资源，或者该第二时频资源包括数据信道对应的时频资源。
具体而言，网络设备可以向该终端设备发送用于配置的指示消息，该指示消息指示该第二时频资源的位置。例如，该指示消息可以为RRC信令消息，但本发明实施例并不限于此。
例如，在LTE中，第二时频资源可以为子帧中第4至第14个OFDM符号中的时频资源。
例如，该第二时频资源可以包括该该子帧中第4至第14个OFDM符号中对应PDSCH的资源。
具体地，第二时频资源可以包括为该用户设备配置的零功率用户状态信息参考信zero-power CSI-RS资源中的至少一个RE。
或者，该第三时频资源可以包括该该子帧中第4至第14个OFDM符号中为该用户设备配置的非零功率用户状态信息参考信Non zero-power CSI-RS资源中的至少一个RE。
因此，本发明实施例中在现有的承载控制信道的第一时频资源中承载波束成形的控制信道，在另外的资源(第二时频资源)中承载该波束成形的控制信道的参考信号，实现了波束成形的控制信道及其参考信号的发送，使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
830，发送波束成形的控制信道及其参考信号。
具体地，网络设备通过该第一时频资源和该第二时频资源分别向终端设备传输该波束成形的控制信道和该波束成形的控制信道对应的参考信号RS。
终端设备进而可以根据接收到的波束成形的控制信道的参考信号对波束成形的控制信道进行解调。例如，终端设备接收搜索空间内的候选资源集合中的候选资源上的信号，在盲检测候选频资源时，例如，该候选资源可能为第一时频资源，
监测第二时频资源，其中，终端设备可以通过上述四种方式中的一种确定第二时频资源中的参考信号。根据第二时频资源上的参考信号对第一时频资源承载的控制信道进行解调，终端设备对接收到的控制信道的信息比特进行解码，并根据自己的ID进行CRC校验，如果校验通过，则成功接收到发给自己的控制信道，即上述盲检测的候选资源即为第一时频资源。如果校验失败，则基站并未在该候选资源上发送控制信道给自己，即上述盲检测的候选资源不是第一时频资源。
因此，本发明实施例通过确定出承载波束成形的控制信道及其参考信号的资源，实现了传输波束成形的控制信道及其参考信号。使得在现有系统中通过波束成形提高控制信道的覆盖成为可能。
并且，本发明实施例中通过波束成形的控制信道以及用于其解调的参考信号的设计，相比传统控制信道提高了控制信道的覆盖和性能，尤其是利用高频段载波的小区的覆盖。同时，波束成形的控制信道的引入对传统终端设备的兼容性没有影响或者影响很小。
