Description

一种参考信号传输的方法及装置
本申请要求于2016年11月04日提交中国专利局、申请号为201610965398.1、申请名称为“一种参考信号传输的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信技术领域，尤其涉及一种参考信号传输的方法及装置。
背景技术
全双工技术是指在相同的时频资源上节点能够同时支持信号的发送和接收，为了提高频谱效率，基站可以采用全双工技术为终端提供服务，目前，将全双工技术应用于基站与终端的通信过程中时，基站侧可以实现全双工，即基站可以利用同一信道同时发送下行数据和接收上行数据，由于终端侧采用全双工技术会使终端之间存在较强的干扰，所以终端侧采用半双工，即终端可以利用一个信道完成数据的收发，在同一时刻同一终端只能在该信道上发送数据或者只能接收数据，不能同时进行数据的收发。
然而，在基站采用全双工技术与终端进行通信的过程中，在同一时刻，会存在终端向基站发送数据，同时其他终端接收基站发送的数据的情况，或者是对于两个相邻的基站，在同一时刻，会存在处于小区边缘的部分终端向第一基站发送数据，同时处于小区边缘的其他终端接收第二基站发送的数据的情况，终端向基站发送的上行信号会对基站向其他终端发送的下行信号产生干扰。
发明内容
本发明实施例提供一种参考信号传输的方法及装置，能够解决在实现基站全双工通信时，终端向基站发送的上行信号对基站向其他终端发送的下行信号产生干扰的问题。

另一方面，本发明实施例提供一种参考信号传输的方法，包括：第一终端接收基站发送的上行参考信号配置信息，然后根据上行参考信号配置信息向基站发送第一类参考信号和第二类参考信号，其中，上行参考信号配置信息包含第一类参考信号的配置信息，以及第一终端需发送的第二类参考信号的配置信息。可见，第一终端可以根据终端配置的上行参考信号配送信息发送上行参考信号，以使得基站可规定第二终端可以对第一终端发送的上行参考信号进行测量，进而就可以通过测量结果确定第一终端向基站发送的上行信号对基站向第二终端发送的下行信号产生的干扰，使得基站能够根据测量结果消除该干扰。
另一方面，本发明实施例还提供一种参考信号传输的方法，包括：第二终端接收基站发送的下行参考信号配置信息，然后根据下行参考信号配置信息进行下行测量。其中，下行参考信号配置信息中包含第一类参考信号的配置信息，以及基站需向第二终端发送的第二类参考信号的配置信息，或者，下行参考信号配置信息包含基站需向第二终端发送的第二类参考信号的配置信息，以及第一终端需向基站发送的第二类参考信号的配置信息。可见，第二终端可以根据基站发送的下行参考信号配置信息进行测量，相当于基站可以规定第二终端既对基站向第二终端发送的下行参考信号进行测量，又对第一终端向基站发送的上行参考信号进行测量，从而根据测量结果对第一终端和第二终端进行协调调度，以消除终端之间的干扰。
在一种可能的设计中，第二终端根据下行参考信号配置信息进行下行测量的方法为，当下行参考信号配置信息中包含第一类参考信号的配置信息，以及基站向第二终端发送的第二类参考信号的配置信息时，第二终端分别对第一终端发送的第一类参考信号，以及基站向第二终端发送的第二类参考信号进行下行测量；当下行参考信号配置信息包含基站向第二终端发送的第二类参考信号的配置信息，以及第一终端向基站发送的第二类参考信号的配置信息时，第二终端分别对第一终端发送的第二类参考信号，以及基站向第二终端发送的第二类参考信号进行下行测量。
另一方面，本发明实施例提供一种参考信号传输的方法，包括：第一基站向所服务的第一终端发送上行参考信号配置信息，从而使第一终端根据上行参考信号配置信息向第一基站发送上行参考信号，第二基站向所服务的第二终端发送下行参考信号配置信息；其中，上行参考信号配置信息包含第一类参考信号的配置信息，下行参考信号配置信息中包含第一类参考信号的配置信息，以及第二基站需向第二终端发送的第二类参考信号的配置信息；或者，上行参考信号配置信息中包含第一终端需发送的第一类参考信号的配置信息，以及第一终端需发送的第二类参考信号的配置信息，下行参考信号配置信息包括第一类终端需向第一基站发送的第一类参考信号的配置信息，以及第二基站需向第二终端发送的第二类参考信号的配置信息。可见第一基站规定第一终端需发送的上行参考信号，第二基站规定第二终端需测量的参考信号，使得第二终端不仅可以测量第二基站向第二终端发送的下行参考信号，还可以测量第一终端向第一基站发送的上行参考信号，进而就可以通过测量结果确定第一终端向第一基站发送的上行信号对第二基站向第二终端发送的下行信号产生的干扰，使得基站能够根据测量结果对第一终端和第二终端进行协调调度，以消除终端之间的干扰。

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，所描述的实施例仅仅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做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、终端，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
2)、基站，又称为无线接入网(Radio Access Network，RAN)设备是一种将终端接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)，未来网络，如5G网络(如应用新无线(new radio)技术的网络)中的继续演进的节点B(gNB)。此外，还可以包括Wifi接入点(Access Point，AP)，收发节点(transmission&reception point，TRP)等。举例而言，基站可以为演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、无线保真(Wireless Fidelity，WIFI)、接入点(Access Point，AP)，传输点(transmission and receiver point，TRP或者transmission point，TP)等，还可以为5G，如NR(new radio)，系统中的gNB，或，传输点(TRP(transmitting and receiving point)或TP(transmission point))，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，数据单元(DU，data unit)等。在一些部署中，gNB可以包括控制单元(CU，control unit)和DU。gNB还可以包括射频单元(RU，radio unit)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU实现RRC(无线资源控制，radio resource control)，PDCP(packet data convergence protocol，分组数据汇聚层协议)层的功能，DU实现RLC(radio link control,无线链路控制)、MAC(media access control,媒体接入控制)和PHY(physical)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。
3)、本发明的说明书和权利要求书中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述对象的特定顺序。例如，第一类参考信号和第二类参考信号等是用于区别不同的参考信号，而不是用于描述参考信号的特征顺序。另外，本发明实施例中的第一终端是指在一个时间段内需要向终端发送上行信号的终端，第二终端是指在该时间段内，需要接收基站发送的下行信号的终端。可以理解的是，在不同的时间段内，一个终端可能是第一终端也可能是第二终端，例如，在一个时间段内，终端A在向基站发送信号，则在该时间段终端A是第一终端，而在另一个时间段内，终端A在接收基站发送的信号，则在该时间段终端A是第二终端。
为了消除终端向基站发送的上行信号对基站向其他终端发送的下行信号产生的干扰，第二终端需分别测量第一终端向基站发送的上行信号的信号质量，以及基站向第二终端发送的下行信号的信号质量。现有技术中，基站可以指示第二终端在特定带宽内测量不同基站发送的CSI-RS(Channel state information reference signal，信道状态信息参考信号)，从而获取不同基站发送的CSI-RS的RSRP值，或者基站可以指示终端第一终端在特定带宽内发送SRS，进而基站可以测量第一终端发送的SRS(sounding reference signal，测量参考信号)的RSRP(Reference Signal Receiving Power，参考信号接收功率)值，然而，由于第二终端只能测量基站向第二终端发送的下行参考信号，而无法测量第一终端向基站发送的上行信号，所以现有技术中第二终端只能确定基站向其他终端发送的下行信号对基站向自身发送的下行信号产生的干扰，而无法确定第一终端向基站发送的上行信号对基站向自身发送的下行信号产生的干扰，所以采用现有的参考信号测量方法无法消除第一终端向基站发送的上行信号对基站向第二终端发送的下行信号产生的干扰。
为了解决上述问题，本发明实施例中，基站可以向第一终端发送SRS的配置信息以及CSI-RS的配置信息，并向第二终端发送待测CSI-RS的配置信息，其中，待测CSI-RS既包括第一终端向基站发送的CSI-RS，又包括基站向第二终端发送的CSI-RS。从而使得第一终端可以向基站发送SRS和CSI-RS，第二终端既可以测量第一终端向基站发送的CSI-RS，又可以测量基站向第二终端发送的CSI-RS。或者，基站向第一终端发送SRS的配置信息，向第二终端发送待测SRS的配置信息以及待测CSI-RS的配置信息，使得第二终端既可以测量第一终端向基站发送的SRS，又可以测量基站向第二终端发送的CSI-RS。使得第二终端既能够对基站向第二终端发送的下行信号进行测量，又能够对第一终端向基站发送的上行信号进行测量，从而根据测量结果确定第一终端向基站发送的上行信号对基站向第二终端发送的下行信号产生的干扰，进而基站可以根据测量结果来协调终端之间的干扰。
本发明实施例提供的参考信号传输的方法可以应用于无线通信系统中，无线通信系统可以包括一个基站或多个基站，以及由这些基站服务的终端，本发明实施例提供了一种可能的无线通信系统的架构示意图，如图1所示，该系统中包括基站、第一终端以及第二终端，图1中示例性的示出了两个基站，以及每个基站服务的第一终端和第二终端，实际上，每个基站可以服务于多个第一终端和多个第二终端。
在同一时刻，第一终端向基站发送的上行信号会对基站向第二终端发送的下行信号产生干扰，具体的，参照图1，同一基站服务的第一终端发送的上行信号，会对该 基站向第二终端发送的下行信号产生干扰。此外，对于第一基站和第二基站服务范围边缘的两个相邻的终端，第一基站服务的第一终端向第一基站发送的上行信号，会对第二基站向所服务的第二终端发送的下行信号造成干扰。
需要说明的是，在本发明实施例中基站采用全双工技术为终端提供服务，即基站可以同时进行信号的发送与接收，例如，基站可以在接收第一终端发送的上行信号的同时向第二终端发送下行信号。终端可以采用半双工的工作模式，即终端可以发送上行信号，也可以接收下行信号，但是不能同时进行上行信号的发送和下行信号的接收。
为了解决终端之间互相产生干扰的问题，本发明实施例提供了一种参考信号传输的方法，可以应用于图1a所示的场景中，即针对同一基站服务的第一终端和第二终端进行信号测量，以解决同一基站服务的第一终端和第二终端之间存在信号干扰的问题，如图2所示，该方法包括：
201、基站向第一终端发送上行参考信号配置信息。
其中，上行参考信号为第一终端需向基站发送的参考信号，用于基站或者其他终端进行上行测量，上行参考信号只包括第一类参考信号，或者上行参考信号包括第一类参考信号和第二类参考信号，其中第一类参考信号为第一终端需向基站发送的参考信号，一般用于基站测量上行信道质量，例如可以为SRS，在本发明实施例中，第二终端也可以对第一类参考信号进行测量。在现有技术中，第二类参考信号为基站需向第二终端发送的下行参考信号，例如可以为CSI-RS或者CRS(Cell-specific reference signal，小区级参考信号)，在本发明实施例中，为了使第二终端能够测量第一终端向基站发送的上行参考信号，还可以规定第一终端发送第二类参考信号，以实现第二终端对第一终端发送的第二类参考信号进行测量。以下均以第一类参考信号为SRS，第二类参考信号为CSI-RS为例进行说明。
上行参考信号配置信息用于指示第一终端发送上行参考信号，其中，上行参考信号配置信息包括第一类参考信号的配置信息，或者包括第一类参考信号的配置信息和第二类参考信号的配置信息。
需要说明的是，基站可以向第一终端发送RRC消息，在RRC消息中携带上行参考信号配置信息，或者基站也可以采取其他方式向第一终端发送上行参考信号配置信息，本发明实施例对此不做限制。
202、第一终端接收基站发送的上行参考信号配置信息。
203、第一终端根据上行参考信号配置信息向基站发送上行参考信号。
可以理解的是，当上行参考信号配置信息包括SRS的配置信息时，第一终端向基站发送SRS。
当参考信号配置信息包括SRS的配置信息和CSI-RS的配置信息时，第一终端向基站发送SRS和CSI-RS。
204、基站接收第一终端发送的上行参考信号。
205、基站向第二终端发送下行参考信号配置信息。
其中，当上行参考信号配置信息包括SRS的配置信息时，下行参考信号配置信息中包含第二终端待测的SRS的配置信息，以及第二终端待测的CSI-RS的配置信息，其中第二终端待测的SRS为第一终端向基站发送的SRS，第二终端待测的CSI-RS为 基站向第二终端发送的CSI-RS；
当上行参考信号配置信息中包含第一终端需发送的SRS的配置信息，以及第一终端需发送的CSI-RS的配置信息时，下行参考信号配置信息包括第二终端待测的CSI-RS的配置信息，其中第二终端待测的CSI-RS包括第一终端向基站发送的CSI-RS，以及基站向第二终端发送的CSI-RS。
206、第二终端接收基站发送的下行参考信号配置信息。
需要说明的是，步骤201和步骤205可以同时执行也可以以一定的先后顺序执行，本发明实施例对此不作限制，图3中仅示出了其中一种可能的执行顺序，步骤203与步骤207需同时执行。
207、第二终端根据下行参考信号配置信息进行下行测量。
需要说明的是，为了消除第一终端向基站发送的上行信号对基站向第二终端发送的下行信号产生的干扰，第二终端需分别对第一终端向基站发送的上行信号以及基站向第二终端发送的下行信号进行测量。本发明实施例提供了两种测量方案。
第一种、当下行参考信号配置信息中包含第二终端待测的SRS的配置信息，以及第二终端待测的CSI-RS的配置信息时，第二终端分别对第一终端向基站发送的SRS，以及基站向第二终端发送的CSI-RS进行下行测量。
可以理解的是，此时第二终端测量的上行信号为：第一终端向基站发送的SRS，第二终端测量的下行信号为：基站向第二终端发送的CSI-RS，通过测量可以确定第一终端和第二终端之间的干扰强度，进而可以将测量结果上报给基站，使基站对第一终端和第二终端进行协调调度，以消除第一终端和第二终端之间的干扰。
第二种、当下行参考信号配置信息为第二终端待测的CSI-RS的配置信息时，第二终端分别对第一终端向基站发送的CSI-RS，以及基站向第二终端发送的CSI-RS进行下行测量。
可以理解的是，此时第二终端测量的上行信号为：第一终端向基站发送的CSI-RS，第二终端测量的下行信号为：基站向第二终端发送的CSI-RS，通过测量可以确定第一终端和第二终端之间的干扰强度，进而可以将测量结果上报给基站，使基站对第一终端和第二终端进行协调调度，以消除第一终端和第二终端之间的干扰。
还需说明的是，第二终端需分别对每组参考信号进行独立测量和上报，以上述第二种测量方案为例，第二终端需要分别对第一终端此次向基站发送的CSI-RS和基站此次向第二终端发送的CSI-RS这两组测量信号进行测量，并上分别上报对这两组参考信号的测量结果。
本发明实施例提供的参考信号传输的方法，基站向第一终端发送上行参考信号配置信息，使得第一终端根据上行参考信号配置信息向基站发送上行参考信号，且基站还会向第二终端发送下行参考信号配置信息，使得第二终端根据下行参考信号配置信息进行下行测量，其中，当上行参考信号配置信息为第一类参考信号的配置信息时，下行参考信号配置信息中包含第一类参考信号的配置信息，以及基站需向第二终端发送的第二类参考信号的配置信息；当上行参考信号配置信息中包含第一类参考信号的配置信息，以及第二类参考信号的配置信息时，下行参考信号配置信息包括基站需向第二终端发送的第二类参考信号的配置信息以及第一终端需向基站发送的第二类参考 信号的配置信息，与现有技术相比，本方案中基站向第二终端发送下行配置信息，使得第二终端不仅可以测量基站向第二终端发送的第二类参考信号，还可以测量第一终端向基站发送的第一类参考信号或第一终端向基站发送的第二类参考信号，即第二终端既能够对基站向第二终端发送的下行参考信号进行测量，又能够对第一终端向基站发送的上行参考信号进行测量，从而使得基站能够通过测量结果确定第一终端向基站发送的上行信号对基站向第二终端发送的下行信号产生的干扰，使得基站能够根据测量结果对第一终端和第二终端进行协调调度，以消除终端之间的干扰。
本发明实施例提供的参考信号传输的方法还可以应用于图1b所示的场景中，即针对第一基站服务的第一终端和第二基站服务的第二终端进行信号测量，以解决第一终端向第一基站发送的上行信号，对第二基站向第二终端发送的下行信号造成干扰的问题，如图3所示，该方法包括：
301、第一基站向所服务的第一终端发送上行参考信号配置信息。
其中，上行参考信号为第一终端需向第一基站发送的参考信号，具体可参见上述步骤201中对上行参考信号的相关描述，此处不再赘述。
上行参考信号配置信息用于指示第一终端向第一基站发送上行参考信号配置信息，上行参考信号配置信息包括第一类参考信号的配置信息，或者上行参考信号配置信息包括第一类参考信号的配置信息，以及第二类参考信号的配置信息。
302、第一终端接收第一基站发送的上行参考信号配置信息。
303、第一终端根据上行参考信号配置信息向第一基站发送上行参考信号。
可以理解的是，当上行参考信号配置信息包括SRS的配置信息时，第一终端向第一基站发送SRS。
当参考信号配置信息包括SRS的配置信息和CSI-RS的配置信息时，第一终端向第一基站发送SRS和CSI-RS。
304、第一基站接收第一终端发送的上行参考信号。
305、第二基站向第二终端发送下行参考信号配置信息。
需要说明的是，第一基站可以通过基站间的接口将上行参考信号配置信息共享给第二基站，进而第二基站能根据第一基站的上行参考信号配置信息来生成下行参考信号配置信息。
其中，当上行参考信号配置信息包括SRS的配置信息时，下行参考信号配置信息中包含第二终端待测的SRS的配置信息，以及第二终端待测的CSI-RS的配置信息，第二终端待测的SRS为第一终端向第一基站发送的SRS，第二终端待测的CSI-RS为第二基站需向第二终端发送的CSI-RS；
当上行参考信号配置信息中包含第一终端需发送的SRS的配置信息，以及第一终端需发送的CSI-RS的配置信息时，下行参考信号配置信息为第二终端待测的CSI-RS的配置信息，此处第二类终端待测的CSI-RS包括第一终端向第一基站发送的CSI-RS，以及第二基站向第二终端发送的CSI-RS。
306、第二终端接收第二基站发送的下行参考信号配置信息。
需要说明的是，步骤301和步骤305可以同时执行也可以以一定的先后顺序执行，本发明实施例对此不作限制，图3中仅示出了其中一种可能的执行顺序，步骤303与 步骤307需同时执行。
307、第二终端根据下行参考信号配置信息进行下行测量。
需要说明的是，为了消除第一终端向第一基站发送的上行信号对第二基站向第二终端发送的下行信号产生的干扰，第二终端需分别对第一终端向第一基站发送的上行信号以及第二基站向第二终端发送的下行信号进行测量。本发明实施例提供了两种测量方案。
第一种、当下行参考信号配置信息中包含第二终端待测的SRS的配置信息，以及第二终端待测的CSI-RS的配置信息时，第二终端分别对第一终端向第一基站发送的SRS，以及第二基站向第二终端发送的CSI-RS进行下行测量。
可以理解的是，此时第二终端测量的上行信号为：第一终端向第一基站发送的SRS，第二终端测量的下行信号为：第二基站向第二终端发送的CSI-RS，通过测量可以确定第一终端和第二终端之间的干扰强度，进而可以将测量结果上报给第二基站，使第二基站对第一终端和第二终端进行协调调度，以消除第一终端和第二终端之间的干扰。
第二种、当下行参考信号配置信息为第二终端待测的CSI-RS的配置信息时，第二终端分别对第一终端向第一基站发送的CSI-RS，以及第二基站向第二终端发送的CSI-RS进行下行测量。
可以理解的是，此时第二终端测量的上行信号为：第一终端向第一基站发送的CSI-RS，第二终端测量的下行信号为：第二基站向第二终端发送的CSI-RS，通过测量可以确定第一终端和第二终端之间的干扰强度，进而可以将测量结果上报给第二基站，使第二基站对第一终端和第二终端进行协调调度，以消除第一终端和第二终端之间的干扰。
还需说明的是，第二终端需对不同组的参考信号进行独立测量和上报。
本发明实施例提供的参考信号传输的方法，第一基站向第一终端发送上行参考信号配置信息，使得第一终端根据上行参考信号配置信息向第一基站发送上行参考信号，且第二基站还会向第二终端发送下行参考信号配置信息，使得第二终端根据下行参考信号配置信息进行下行测量，其中，当上行参考信号配置信息为第一类参考信号的配置信息时，下行参考信号配置信息中包含第二终端待测的第一类参考信号的配置信息，以及第二基站需向第二终端发送的第二类参考信号的配置信息；当上行参考信号配置信息中包含第一类参考信号的配置信息，以及第一终端需发送的第二类参考信号的配置信息时，下行参考信号配置信息为第一终端需向第一基站发送的第二类参考信号的配置信息以及第二基站需向第二终端发送的第二类参考信号的配置信息，与现有技术相比，本方案中第二终端不仅可以测量第二基站向第二终端发送的第二类参考信号，还可以测量第一终端向第一基站发送的第一类参考信号或第一终端向第一基站发送的第二类参考信号，即第二终端既能够对第二基站向第二终端发送的下行参考信号进行测量，又能够对第一终端向第一基站发送的上行参考信号进行测量，进而就可以通过测量结果确定第一终端向第一基站发送的上行信号对第二基站向第二终端发送的下行信号产生的干扰，使得基站能够根据测量结果对第一终端和第二终端进行协调调度，以消除终端之间的干扰。
以下对上述实施例中的上行参考信号配置信息以及下行参考配置信息进行解释说 明。

时频图样资源信息用于指示一个物理资源块内承载第二类参考信号的时频资源，如图6所示，时频图样1和时频图样2分别表示一组用于承载第二类参考信号的时频资源，其中，第一终端可使用图6中的非空白资源块来发送第二类参考信号。

(4)、用于生成第二类参考信号的配置参数。
其中，根据该配置参数以及用于生成第二类参考信号的序列生成公式可以生成第二类参考信号。
另外，下行参考信号配置信息中的第二终端待测的第一类参考信号的配置信息，是指第二终端待测的第一终端向基站发送的SRS的配置信息，该配置信息中包括以下至少一种：
