Description

一种数据传输的方法及发送端设备、接收端设备
本申请要求在2016年12月30日提交中华人民共和国知识产权局、申请号为201611261964.7、发明名称为“一种数据传输的方法及发送端设备、接收端设备”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
本发明实施例涉及无线通信技术领域，尤其涉及一种数据传输的方法及发送端设备、接收端设备。
背景技术
在LTE系统中，为了提高边缘用户吞吐量，多点协作传输技术被引入，包括多点传输。多点传输的典型技术包括联合传输技术。受限于小区间信息交互的容量和速度，多点传输技术，尤其是联合传输技术并没有做优化。在5G新空口(5th generation new radio，5G NR)系统，随着小区间信息交互能力的提高(如，空中下载(over－the－air，OTA)技术)，联合传输技术需要做进一步优化。该联合传输技术为多个基站或站点使用多个波束联合向一个终端进行数据传输，这种场景可以称之为多波束传输场景。
在5G NR系统，高频传输是一个重要场景。但高频信号视距衰减严重，且绕射能力弱。因此，在高频通信，考虑采用大规模天线阵列。为了降低天线设备的面积，通常考虑多面板(panel)传输，多个面板可以集中或独立摆放。多个面板，可以形成不相关的多个波束，分集增益明显，有利于解决波束阻挡(beam blockage)问题。因此，多波束传输也是5G NR中的一个关键技术。
但是在5G NR系统中，对于多波束传输场景，没有对来自不同方向的数据流作接收增强的技术方案。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。
图1示出了本发明实施例所适用的一种系统架构，基于该系统架构可实现对数据传输的流程的控制，本发明实施例提供的数据传输的系统架构中包括多个发送端设备101和接收端设备102。
该发送端设备101可以为基站、基站下负责的站点；该接收端设备102可以为移动终端。在多个波束的无线通信系统中，多个发送端设备101可以通过联合传输技术使用多波束向该接收端设备102接收该多个发送端设备101传输的数据。
在本发明实施例中，多个波束可以是一个发送端设备101中的多个波束，也可以是多个发送端设备101的多个波束，比如第一个发送端设备101可以使用一个波束，第二个发送端设备101可以使用两个波束，对应的接收端设备102在接收时，需要使用三个波束来接收这两个发送端设备101传输的数据。
多个发送端设备101在使用联合传输技术时，由这多个发送端设备101中的主设备负责分配传输数据时使用的波束，并向每个发送端设备101进行通知，从而使得每个发送端设备101都会知道自己可以使用哪些波束来完成数据传输。
基于上述描述，图2示例性的示出了本发明实施例提供的一种数据传输的方法的流程，适用于包括多个波束的无线通信系统。
如图2所示，该流程具体步骤包括：
步骤201，发送端设备确定向接收端设备发送数据所使用的至少一个发送波束，以及波束指示信息。
步骤202，发送端设备向接收端设备发送所述波束指示信息。
步骤203，发送端设备使用至少一个发送波束进行数据传输。
步骤204，接收端设备从发送端设备接收波束指示信息，根据波束指示信息确定接收发送端设备传输的数据所使用的至少一个接收波束。
步骤205，接收端设备使用确定的至少一个接收波束接收发送端设备传输的数据。
在本发明实施例中，发送端设备在向接收端设备进行数据传输时，需要先确定向接收端设备发送数据所使用的至少一个发送波束，该所使用的至少一个发送波束的确定方式为现有的通用技术，在本发明实施例中不再描述。
在确定出向接收端设发送数据所使用的至少一个发送波束时，还需要确定出波束指示信息，该波束指示信息可以指示接收端设备用于接收数据的每个接收波束。
具体的，该波束指示信息可以为每个接收波束的信息，该每个接收波束的信息可以指示接收端设备确定出用于接收数据的每个接收波束。该波束指示信息也可以为每个发送波束的信息，该每个发送波束的信息可以指示接收端设备确定出用于接收数据的每个接收波束。
通过指示出每个接收波束的信息或者发送波束的信息，可以使得接收端设备知道通过哪些接收波束接收的数据的信号的功率最强，并利用大功率差的优势增强迭代干扰消除的效果，从而增强了接收端设备接收多波束数据的能力。
可选地，上述波束指示信息可以为单层信令结构或双层信令结构。该波束指示信息为单层信令结构时，可以为物理层指示信令，通过该物理层指示信令指示发送波束和/或接收波束的索引值。该波束指示信息为双层信令结构时，可以为数据链路层指示信令和物理层指示信令的结合，通过数据链路层指示信令指示发送波束和/或接收波束集合，通过物理层指示信令指示该发送波束或接收波束集合中的发送波束和/或接收波束。
为了使得接收端设备在接收数据时知道自己通过接收波束接收的是哪个传输层，发送端设备在确定出波束指示信息时，还需要确定发送波束和/或接收波束与传输层的对应关系。该一个发送波束和/或接收波束可以对应一个或多个传输层，本发明实施例对此不做限制。
发送端设备可以向接收端设备发送上述波束指示信息以及上述确定的发送波束和/或接收波束与传输层的对应关系。发送端设备将所述波束指示信息和所述发送波束和/或接收波束与传输层的对应关系通过物理层指示信令发送给接收端设备。该波束指示信息以及上述确定的发送波束和/或接收波束与传输层的对应关系可以在一个信令中一个或两个不同的信息域中指示。
举例来说，如图3所示的多点联合传输的场景下，站点BS1和站点BS2联合向终端UE1 进行数据传输。该站点BS1使用发送波束1向终端UE1传输数据，站点BS2使用发送波束2向终端UE1传输数据。
该波束指示信息以及发送波束和/或接收波束与传输层的对应关系位于同一个信息域时，可以如表1所示的指示方式。
表1
接收波束1 接收波束1 接收波束1 接收波束2
也就是说，哪个传输层由哪个波束接收都一一罗列出来。
该波束指示信息以及发送波束和/或接收波束与传输层的对应关系位于不同的信息域时，其中一个信息域中波束指示信息可以如表2所示的防止方式。
表2
接收波束1 接收波束2
该信息域中只指示了使用哪个波束，并没指出哪个波束接收哪个传输层。
该发送波束和/或接收波束与传输层的对应关系可以放置在另一个信息域中，可以为接收波束1:3，表示前3个传输层都由接收波束1接收。接收波束2:1，表示第4(3+1)个传输层由接收波束2接收。
进一步地，发送端设备在确定发送波束和/或接收波束与传输层的对应关系时，可以先确定发送波束和/或接收波束与码字的对应关系，然后再确定码字与所述传输层的映射关系，之后发送端设备将上述波束指示信息以及该码字与所述传输层的映射关系发送给接收端设备。
发送端设备通过波束指示信息以及发送码字与所述传输层的映射关系来指示接收端设备采用相应的接收波束来接收发送端设备传输的数据，以及指示码字所对应的传输层，使得接收端设备进一步利用传输层之间的功率差异，提高多个码字间干扰消除的能力，增强了接收端设备接收多波束方向数据的能力。
如图3所示的场景，站点BS1传输的信号S1、S2和S3对应码字1，站点BS2传输的信号S4对应码字2。在每个信息域中表示出每个码字上的接收波束的信息。
上述发送波束指示信息以及码字与所述传输层的映射关系可以通过物理层指示信令向接收端设备发送，并且在该物理层指示信令中设置设定比特数的信息位指示所述码字所映射的传输层的层数。具体的，发送端设备可以根据系统的最大的传输层的层数确定设定比特数。
比如，M为当前系统的最大的传输层的层数，则根据该M值，用log2(M)来确定该设定比特数，指示出每个码字所映射的传输层的层数。
也可以是根据协议约定的每个码字最大的传输层的层数确定上述设定比特数，从而指示出每个码字所映射的传输层的层数。例如一个码字动态对应1个或2个层数，则每个码字仅需要1比特的信息位来指示该码字所映射的传输层的层数。
上述物理层指示信令中也可以设置特定信息位指示码字与所述传输层的映射组合的索引值。例如，对于2个码字，每个码字映射最多2个传输层的情况。其码字与传输层的映射的组合分别为{1,1}，{1,2}，{2,1}，{2,2}。因此，可以使用2比特的特定信息位来指示这四种情况。当前码字和传输层的映射关系为{1,2}时，特定信息位为01。
通过动态的码字和传输层的映射技术，可以灵活的支持不同波束方向的数据对应在不同码字的各种传输层的情况。
可选地，发送端设备在向接收端设备发送波束指示信息时，可以是隐性的向接收端设备指示，具体的，发送端设备可以向接收端设备发送QCL信息，接收端设备可以根据该QCL信息与波束指示信息的对应关系，确定出用于接收数据的接收波束。
上述实施例表明，发送端设备通过波束指示信息指示接收端设备采用相应的接收波束来接收发送端设备传输的数据，使得接收端设备能够选择合适的接收波束接收数据，提高接收信干噪比。
基于上述实施例，接收端设备采用指示的接收波束可以识别出信号功率强的接收波束，主要包括下述几种方式：
方式1，通过指示出不同波束接收方向对应不同的码字，识别出每个波束方向上可信度强(接收功率较大)的码字，对其优先检测。
方式2：通过指示出不同波束接收方向对应不同的码字，识别出每个波束方向上可信度强(接收功率较大)的码字，对其优先检测。再检测可信度弱的码字，并将可信度强的码字作为干扰消除掉。
方式3：通过指示出不同波束接收方向对应不同的码字，识别出每个波束方向上可信度强(接收功率较大)的码字，对其优先检测。再将检测结果带入其他波束，作为干扰项消除，进一步提高有用信号的检测效果。
如图4所示的场景，其传输模型为Y＝H1V1S1+H2V2S2+Inter+noise。此时，接收端设备进行信号检测时，可以使用下述几种方式：
首先如图4所示，根据波束指示信息，接收端设备使用接收波束1接收S1，S2作为干扰；接收波束2接收S2，S1作为干扰。
方式一
根据波束指示信息，接收波束1接收S1，S1作为强信号优先检测，S1检测后作为已知干扰消除后检测S2，继而将S2作为干扰消除后，再检测S1。再次检测的S1，由于消除了干扰S2，检测正确率提高；接收波束2接收S2，S2作为强信号优先检测，S2检测后作为已知干扰消除后检测S1，继而将S1作为干扰消除后，再检测S2。再次检测的S2，由于消除了干扰S1，检测正确率提高。
方式二
根据波束指示信息，接收波束1接收S1，检测得到S1’；接收波束2接收S2，检测得到S2’。将S2’代入到接收波束1接收模型，作为干扰项消除，再检测S1。同理，将S1’代入到接收波束2的接收模型，作为干扰项消除，再检测S2。
相应地，接收端设备在接收到发送端设备发送的波束指示信息时，需要根据该波束指示信息确定接收发送端设备传输的数据所使用的至少一个接收波束。当该波束指示信息包括至少一个接收波束的信息时，接收端设备根据该波束指示信息中指示的至少一个接收波束的信息确定出用于接收发送端设备传输的数据使用的至少一个接收波束。
当波束指示信息包括至少一个发送波束的信息时，该接收端设备需要根据波束指示信息中指示的至少一个发送波束的信息以及发送波束与接收波束的对应关系，确定至少一个发送波束的信息所对应的至少一个接收波束的信息。该发送波束与接收波束的对应关系为预先获知的，接收端设备在使用时可以查找该发送波束与接收波束的对应关系。然后接收端设备根据至少一个发送波束的信息所对应的至少一个接收波束的信息，确定出用于接收发送端设备传输的数据使用的至少一个接收波束。比如，波束指示信息包括发送波束1和 发送波束2，而接收端设备在查询发送波束与接收波束的对应关系时，发现发送波束1对应接收波束a，发送波束2对应接收波束b。因此，接收端设备确定使用接收波束a接收发送波束1传输的数据，使用接收波束b接收发送波束2传输的数据。
当接收端设备接收到发送端设备发送的波束指示信息和发送波束和/或接收波束与传输层的对应关系时，接收端设备根据波束指示信息以及发送波束和/或接收波束与传输层的对应关系，确定接收发送端设备传输的数据时所使用的至少一个接收波束以及至少一个接收波束所需接收的传输流。也就是说，接收端设备不光知道使用哪个接收波束接收传输的数据，还可以知道接收波束接收的是哪个传输层中的传输流。
上述发送端设备发送的波束指示信息和发送波束和/或接收波束与传输层的对应关系是通过物理层指示信令接收的，在物理层指示信令中的放置格式和标识方式已在上述实施例中描述，不再赘述。
