技术领域
本申请实施例涉及通信技术，尤其涉及一种信号传输方法及装置。
背景技术
随着用户对通信要求的不断提高，高级长期演进(Long Term Evolution Advance，简称：LTE-Advanced)系统中引入了多点协作传输与接收(Coordinated Multi-Point Transmission and Reception，简称：CoMP)。CoMP是指地理位置上分离的多个传输点，协同参与一个用户设备的数据传输或者联合接收一个用户设备发送的数据。其中，协同参与一个用户设备的数据传输包括多种场景，如多个传输点同时为一个用户设备传输数据，或者动态点选择即多个传输点协作调度最终选择其中一个传输点为用户设备传输数据，或者协作调度或者协作波束成型即多个传输点通过协作调度或者协作波束成型降低传输点之间的干扰，提高整体的系统性能。联合接收是指多个传输点同时接收用户设备的上行数据，然后传输点间进行合并，提高上行数据的传输性能。
处于CoMP下的用户设备，为了在链路中进行频率选择性调度，需向上述多个传输点分别发送探测参考信号(Sounding Reference Signal，简称：SRS)来实现对信道质量的探测。这就需要多个传输点所属的基站分别为该处于CoMP下的用户设备进行SRS资源配置，从而导致资源浪费；另外，该处于CoMP下的用户设备向多个传输点分别发送SRS还会导致信道质量获取的延时。
发明内容

具体实施方式
本申请实施例的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
下一代移动通信系统要求大容量和高质量的数据传输。其中，多输入多输出(Multiple Input Multiple Output，简称：MIMO)技术被认为是可实现未来高速数据传输的关键技术之一。传统的集中式MIMO系统的多根发射天线均集中于基站(Base Station，简称：BS)端。与集中式MIMO系统不同，分布式MIMO系统的多根发射天线分布于不同的地理位置，其各对收发链路之间更加独立，因此，分布式MIMO系统具有大容量、低功耗、更好的覆盖、对人体的低电磁损害等优势，被认为是未来无线通信系统的备选方案之一。
在分布式MIMO系统，为了提高边缘用户设备的信号可靠性以及边缘小区的吞吐量，可以考虑采用多传输点多数据流的传输方法。具体地，基站可以采用接收用户设备发送的SRS的方式获取各传输点的信道质量，但是多传输点下需要用户设备多次发送SRS，从而导致资源浪费，信道质量获取的延时。
针对上述问题，本申请实施例提供一种信号传输方法及装置，通过设备，例如基站，间交互参考信号配置信息实现参考信号，例如SRS，的协作传输，节省资源的同时也减小了信道质量获取的时延。
对于应用场景，本申请实施例可以应用于时分双工(Time Division Duplexing，简称：TDD)系统和频分双工(Frequency Division Duplexing，简称：FDD)系统。本申请实施例可以应用于单载波系统和多载波系统。本申请实施例可以应用于高频(高于6GHz频段)通信系统和低频(低于6GHz频段)通信系统。
图1为本申请信号传输方法实施例一的信令交互图。如图1所示，该信号传输方法包括：
S101、第一设备接收第二设备发送的参考信号配置信息。
对应地，第二设备发送参考信号配置信息给第一设备。
为了让第一设备和第二设备可以同时接收到后续做协作传输的用户设备发送的参考信号，第二设备需将协作传输的用户设备的参考信号配置信息通知给第一设备。
其中，第一设备和第二设备可以分别具体为第一基站和第二基站，但本申请实施例不以此为限制。
该参考信号配置信息包括参考信号资源位置信息和/或参考信号序列参数，参考信号资源位置信息用于表示传输参考信号的时域和/或频域资源，参考信号序列参数包括生成参考信号序列所需的全部或部分参数，具体可参考现有技术有关参考信号序列的说明，此处不再赘述；参考信号用于进行信道质量 探测。也就是说，该参考信号配置信息可以包括参考信号资源位置信息；或者，该参考信号配置信息可以包括参考信号序列参数；或者，该参考信号配置信息可以包括参考信号资源位置信息和参考信号序列参数。
对于参考信号配置信息所包括的内容可以根据实际需求进行设置。当参考信号配置信息仅包括参考信号资源位置信息时，本领域技术人员可以理解，第一设备与第二设备已协商好该参考信号配置信息包括的参考信号资源位置信息所对应的参考信号序列参数；同理，当参考信号配置信息仅包括参考信号序列参数时，本领域技术人员可以理解，第一设备与第二设备已协商好该参考信号配置信息包括的参考信号序列参数所对应的参考信号资源位置信息。或者，第一设备已被配置参考信号序列参数与参考信号资源位置信息的对应关系。
在该方案中，参考信号资源位置信息可以具体为参考信号在时频域资源上的图案信息。例如，如图2所示，其中，图案1、图案2和图案3为三种可能的SRS资源位置分布，此时，参考信号资源位置信息的具体子帧位置可以是协议定义的，也可以是自定义的，本申请实施例不予限制。另外，参考信号资源位置信息也可以具体为时域资源信息和/或频域资源信息，其中，该时域资源信息至少包括子帧位置信息和/或符号位置信息。如果后续做协作传输的用户设备发送的参考信号占据全带宽频域资源，则参考信号资源位置信息可以只包含时域资源信息，例如，子帧位置信息、符号位置信息、子帧位置信息和符号位置信息；如果后续做协作传输的用户设备发送的参考信号仅在预设的固定个符号位置上发送，则参考信号资源位置信息可以只包含频域资源信息。例如，在现有长期演进(Long Term Evolution，简称：LTE)系统中，SRS仅在上行子帧或者特殊子帧的最后一个或多个符号上传输，如图3所示。该特殊子帧(special subframe)是指TDD系统中用于上下行过渡的子帧，该特殊子帧中包括三部分：下行部分(The downlink part of the special subframe，简称：DwPTS)，保护间隔(guard period，简称：GP)，和上行部分(The uplink part of the special subframe，简称：UpPTS)。
可选地，参考信号配置信息还可以包括功率信息，该功率信息用于表示预设功率值或功率计算信息。其中，预设功率值为预先设定的参考信号的功率值；功率计算信息为预先设定的用于确定参考信号的功率的计算信息。
例如，对于服务小区c，用户设备在子帧i上发送SRS的传输功率PSRS定义如下：
PSRS,c(i)＝min{PCMAX,c(i),PSRS_OFFSET,c(m)+10log10(MSRS,c)+PO_PUSCH,c(j)+αc(j)·PLc+fc(i)}
其中，PSRS,c(i)的单位为dBm；
PCMAX,c(i)是配置的在服务小区c子帧i上用户设备的传输功率；
PSRS_OFFSET,c(m)，对于服务小区c在m＝0和m＝1的值是通过高层信令半静态配置的。对于触发类型0的SRS传输(周期性SRS传输)m＝0，对于触发类型1的SRS传输(非周期性SRS传输)m＝1；
MSRS,c是服务小区c在子帧i上SRS传输的带宽，表示为资源块的个数；
fc(i)是对于服务小区c的当前的PUSCH功率控制调制状态；
PO_PUSCH,c(j)和αc(j)在j＝1取值如下：
PO_PUSCH,c(1)＝PO_UE_PUSCH,c,2(1)+PO_NOMINAL_PUSCH,c,2(1)。PO_UE_PUSCH,c,2(1)和PO_NOMINAL_PUSCH,c,2(1)是通过高层参数p0-UE-PUSCH-SubframeSet2-r12和p0-NominalPUSCH-SubframeSet2-r12提供；αc(j)＝αc,2∈{0,0.4,0.5,0.6,0.7,0.8,0.9,1}，αc,2是通过高层提供的参数alpha-SubframeSet2-r12。
当第一设备和第二设备协同参与第一用户设备的数据传输时，也即第一用户设备处于CoMP下，第一用户设备根据上述参考信号配置信息生成并发送该参考信号配置信息对应的参考信号， 例如，第一用户设备根据上述参考信号配置信息所包括的功率信息确定该参考信号配置信息对应的参考信号的功率。第一设备获知参考信号配置信息所包括的功率信息后，可以更好的根据SRS进行信道状态的测量。
S102、第一设备接收该参考信号配置信息对应的第一用户设备发送的参考信号。
S103、第二设备基于该参考信号配置信息，接收该参考信号配置信息对应的第一用户设备发送的参考信号。
具体地，第一设备按照其接收的参考信号配置信息，配置调度用户设备的参考信号传输，并接收处于CoMP下的用户设备(即第一用户设备)发送的参考信号；第二设备将上述参考信号配置信息配置给处于CoMP下的用户设备，并基于该参考信号配置信息接收该处于CoMP下的用户设备发送的参考信号。
在该参考信号配置信息对应的第一用户设备发送参考信号之后，第一设备和第二设备对该参考信号进行接收。第一设备和第二设备通过接收该参考信号，可以获取与发送该参考信号的第一用户设备的信道特征，进而可以确定是否与该第一用户设备进行数据传输，或者确定具体与第一用户设备进行数据传输的调度策略，包括联合传输或动态点选择传输，或者传输层数或者预编码或者调制编码选择或者时频资源位置选择，等等。
本申请实施例信号传输方法，通过第一设备与第二设备交互参考信号配置信息，实现处于CoMP下的用户设备发送的参考信号(例如SRS)的协作传输，从而无需第一设备和第二设备分别为该处于CoMP下的用户设备配置用于传输参考信号的资源，节省资源；且，该处于CoMP下的用户设备向多个设备(包括第一设备和第二设备)发送同一个参考信号，从而降低不同设备获取信道质量的延时，提高协作传输性能。
在上述实施例的基础上，一种实现方式中，参考信号配置信息可以为处于CoMP下的用户设备的参考信号配置信息。该情况下，第一设备接收参考信号配置信息对应的第一用户设备发送的参考信号，可以包括：第一设备基于参考信号配置信息，接收处于CoMP下的用户设备发送的参考信号。
另一种实现方式中，参考信号配置信息可以为第二设备所服务的任一用户设备的参考信号配置信息。该情况下，第一设备接收第二设备发送的参考信号配置信息之后，该第一设备需确定该参考信号配置信息对应的第一用户设备是否为处于CoMP下的用户设备；若确定该参考信号配置信息对应的第一用户设备是处于CoMP下的用户设备，则第一设备接收该参考信号配置信息对应的第一用户设备发送的参考信号；若确定该参考信号配置信息对应的第一用户设备不是处于CoMP下的用户设备，则第一设备忽略该参考信号配置信息，不做任何后续处理。
下面采用几个具体的实施例，对第一设备基于参考信号配置信息，配置调度用户设备的参考信号传输进行详细说明。
第一种具体实施例中，第一设备接收第二设备发送的参考信号配置信息之后，该信号传输方法还可以包括：第一设备发送第一控制信息给在参考信号资源位置信息上被配置有物理上行共享信道(Physical Uplink Shared Channel，简称：PUSCH)的第二用户设备。
其中，参考信号资源位置信息上未被配置该第二用户设备的参考信号，且参考信号资源位置信息上被配置该第二用户设备的PUSCH。第一控制信息可以包括第一指示信息，该第一指示信息用于指示所述参考信号配置信息中的资源位置信息，或者，该第一指示信息用于指示所述参考信号资源位置信息不用于所述第二用户设备的PUSCH的传输。
当第一指示信息用于指示所述参考信号配置信息中的资源位置信息，第二用户设备根据预先设定(例如协议规定)即可间接确定该第一指示信息所指示的资源位置不用于其PUSCH的传输；当该第一指示信息用于指示所述参考信号资源位置信息不用于所述第二用户设备的PUSCH的传输时，第二用户设备以直接的形式即可确定该第一指示信息所指示的资源位置不用于其PUSCH的传输。直接的形式比如通过某个具体的指示或专用的指示，使第二用户设备确定该第一指示信息所指示的资源位置不用于其PUSCH的传输。
本实施例中，第一设备在上述参考信号资源位置信息上未配置第二用户设备的参考信号，但第一设备在上述参考信号资源位置信息上配置有第二用户设备的PUSCH。因此，第一设备需通知在上述参考信号资源位置信息上被配置有PUSCH的第二用户设备，在所述参考信号资源位置信息上不传输PUSCH。这样，可以避免与所述参考信号配置信息对应的参考信号的传输发生冲突。
对应地，该第二用户设备接收第一设备发送的第一控制信息，并根据该第一控制信息发送PUSCH。其中，第二用户设备根据该第一控制信息发送PUSCH，可具体包括以下两种实现方式：

其中，该第三控制信息用于指示在所述参考信号资源位置信息上被配置参考信号的第三用户设备不发送参考信号。
为本领域技术人员所理解，第三用户设备不发送参考信号，只是代表某一时刻所述参考信号资源位置信息所指示的资源位置不用于发送参考信号，其他时刻所述参考信号资源位置信息所指示的资源位置还是照常发送参考信号，这样并不会干扰第三用户设备的通信。而且如果在当前所述参考信号资源位置信息所指示的资源位置上，第三用户设备没有发送参考信号，基站可以等下个时刻第三用户设备发送了所述参考信号配置信息对应的参考信号后，再调度该第三用户设备发送参考信号。
本实施例中，第一设备在上述参考信号资源位置信息上配置第三用户设备的参考信号。因此，第一设备需通知在上述参考信号资源位置信息上被配置有参考信号的第三用户设备，在所述参考信号资源位置信息上不发送参考信号，以防干扰所述参考信号资源位置信息对应的参考信号的传输。
相应地，该第三用户设备接收第一设备发送的第三控制信息，并确定在所述参考信号资源位置信息上不发送参考信号。

本实施例中，第一设备在上述参考信号资源位置信息上未配置第四用户设备的参考信号，但第一设备在上述参考信号资源位置信息上配置有第四用户设备的PDSCH。因此，第一设备需通知在上述参考信号资源位置信息上被配置有PDSCH的第四用户设备，所述参考信号资源位置信息不用于所述用户设备的PDSCH的接收，以使得一方面避免与所述参考信号配置信息对应的参考信号的传输发生冲突，另一方面保证第四用户设备的PDSCH接收的正确性。

当通过公共信令携带控制信息时，仅本小区中的部分用户设备可以接收到该专用信令。此时，有资源冲突的用户设备接收到该公共信令后，根据该公共信令中携带的控制信息进行后续处理，包括接收PDSCH、发送PUSCH或发送第一参考信号等，具体见上述实施例中描述；而没有资源冲突的用户设备可以不进行任何操作。
