Description

一种信号传输方法和网络设备以及终端设备
本申请要求于2017年1月6日提交中国专利局、申请号为201710011310.7、发明名称为“一种信号传输方法和网络设备以及终端设备”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
本发明涉及通信技术领域，尤其涉及一种信号传输方法和网络设备以及终端设备。
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质量测量，例如用于无线资源管理(radio resource management，RRM)相关测量，这类参考信号可以为小区特定参考信号(cell－specific reference signal，CRS)，从而可以实现用户信道质量的测量和小区选择切换；另一类参考信号用于信道状态信息的测量，从而实现对终端设备的调度。终端设备基于对信道状态信息参考信号(channel state information-reference Signal，CSI-RS)的信道质量测量，得到信道状态信息。
为克服较高频的频段导致的较大传播损耗，一种基于波束赋形技术的信号(包括参考信号)传输机制被采用，以通过较大的天线增益来补偿信号传播过程中的传输损耗。其中，波束赋形的信号包括小区特定的第一类参考信号或用户特定的第二类参考信号等。此外，基站的接收波束赋形技术同时被考虑，波束赋形可包括模拟域的波束赋形、基带域的波束赋形以及模拟域或基带域混合波束赋形中的任意一种。其中，下行信号传输中基站发射侧的波束赋形和终端设备接收侧的波束赋形均可能发生动态变化，为跟踪波束赋形的变化，终端设备可以基于对不同赋形波束下的多个参考信号的信道质量测量，从而得到最优的一个或多个赋形波束。
现有技术中，当信号基于波束赋形技术进行传输时，一旦用户发生移动，可能出现传输信号对应的赋形波束的方向不再匹配移动后的用户位置，从而存在接收信号频繁中断的问题。为跟踪信号传输过程中的赋形波束变化，需要对基于波束赋形技术的信道质量测量结果进行上报。信道质量的测量可以基于波束赋形后的同步信号或小区特定参考信号来完成。相比小区切换，用户在不同赋形波束间的切换更加动态和频繁，因此也需要动态的测量上报机制。类似于CSI信息的上报，赋形波束的信道质量测量结果的上报也可由终端设备通过物理上行控制信道或物理上行共享信道发送给基站。
在基于赋形波束为基础的信号传输过程中，发射侧和接收侧的最优赋形波束均需得到以最大化信号的波束赋形增益和对应的信道质量。现有技术中通常采用的信号传输方法是：基站侧和终端设备侧需要对发射赋形波束和接收赋形波束分别进行波束扫描和波束训练，从而完成最优收发波束对的选取。
综上可知，现有技术中，基站侧和终端设备侧对发射赋形波束和接收赋形波束分别进行波束扫描和波束训练，将使得收发两侧的最优波束训练时间翻倍，处理复杂度增高，资源使用效率降低。
发明内容
本发明实施例提供了一种信号传输方法和网络设备以及终端设备，实现网络设备和终端设备的快速波束校准，从而可简化网络设备或终端设备的波束管理过程，并最大化资源使用效率。
为解决上述技术问题，本发明实施例提供以下技术方案：
第一方面，本发明实施例提供一种信号传输方法，包括：网络设备向终端设备发送N个第一参考信号，所述N为大于或等于1的正整数；所述网络设备向所述终端设备发送物理层控制信令，所述物理层控制信令用于触发所述终端设备向所述网络设备发送基于所述N个第一参考信号的信道质量测量结果，所述物理层控制信令还用于指示所述终端设备向所述网络设备发送M个第二参考信号，所述M为大于或等于1的正整数；所述网络设备接收所述终端设备发送的所述信道质量测量结果；所述网络设备接收所述终端设备发送的所述M个第二参考信号。物理层控制信令用于触发终端设备向网络设备发送基于N个第一参考信号的信道质量测量结果，物理层控制信令还用于指示终端设备向网络设备发送M个第二参考信号，终端设备可以根据该物理层控制信令发送基于N个第一参考信号的信道质量测量结果，终端设备还可以根据该物理层控制信令发送M个第二参考信号，因此本发明实施例中网络设备和终端设备不需要针对发射赋形波束和接收赋形波束分别进行波束扫描和波束训练，由于网络设备接收有基于N个第一参考信号的信道质量测量结果，和M个第二参考信号，因此只需要网络设备进行波束校准即可，实现网络设备和终端设备的快速波束校准，从而可简化终端设备的波束管理过程，并最大化资源使用效率。
在一个可能的设计中，所述信道质量测量结果包括：所述N个第一参考信号中的一个第一参考信号的资源索引。终端设备接收网络设备发送的N个第一参考信号，终端设备可以从N个第一参考信号中选择出一个第一参考信号的资源索引，然后将选择出的该一个第一参考信号的资源索引发送给网络设备，从而网络设备可以根据终端设备上报的该资源索引和赋形波束的关联关系确定出网络设备的较优发射波束，为网络设备进行波束校准提供参考。
在一个可能的设计中，所述第二参考信号的传输带宽小于或等于所述第一参考信号的传输带宽；和/或，所述第二参考信号传输的频域资源为所述第一参考信号传输的频域资源的子集。第一参考信号由网络设备发送，第二参考信号由终端设备发送，通常情况下，网络设备对信号的处理能力要大于终端设备对信号的处理能力，且终端设备的功率受限，终端设备发送第二参考信号的传输带宽要小于或等于网络设备发送第一参考信号的传输带宽，从而保证终端设备在单位频域资源上的信号发送功率足够大。另外，终端设备进行第二参考信号传输的频域资源为网络设备进行第一参考信号传输的频域资源的子集，从而网络设备可以在与终端设备发送的第二参考信号上的相同频域资源范围内进行第一参考信号对应的发射波束和第二参考信号对应的接收波束的校准。
在一个可能的设计中，所述网络设备接收所述终端设备发送的所述M个第二参考信号，包括：所述网络设备接收所述终端设备采用时分的方式重复发送的M个第二参考信号。终端设备重复的发送第二参考信号，共计发M个第二参考信号，网络设备可以采用时分的方式接收第二参考信号，网络设备按照一定的接收间隔重复的接收终端设备发送的第二参考 信号，共接收到来自终端设备发送的M个第二参考信号。

在一个可能的设计中，所述第二参考信号的传输带宽小于或等于所述第一参考信号的传输带宽；和/或，所述第二参考信号传输的频域资源为所述第一参考信号传输的频域资源的子集。第一参考信号由网络设备发送，第二参考信号由终端设备发送，通常情况下，网络设备对信号的处理能力要大于终端设备对信号的处理能力，从而可以配置第二参考信号的传输带宽小于或等于第一参考信号的传输带宽，第二参考信号传输的频域资源为第一参考信号传输的频域资源的子集。
在一个可能的设计中，所述终端设备向所述网络设备发送所述M个第二参考信号，包括：所述终端设备采用时分的方式重复的向所述网络设备发送所述M个第二参考信号。终端设备重复的发送第二参考信号，共计发M个第二参考信号，使得网络设备可以接收到该M个第二参考信号。

在一个可能的设计中，所述信道质量测量结果包括：所述N个第一参考信号中的一个第一参考信号的资源索引。网络设备接收终端设备发送的N个第一参考信号，网络设备可以从N个第一参考信号中选择出一个第一参考信号的资源索引，然后将选择出的一个第一参考信号的资源索引发送给终端设备，使得终端设备可以确定出网络设备所选择的一个第一参考信号的资源索引。

其中，步骤204和步骤203之间没有先后顺序，终端设备接收网络设备发送的N个第一参考信号，终端设备可以对网络设备发送的N个第一参考信号进行信道质量测量，生成基于N个第一参考信号的信道质量测量结果。
在本发明的一些实施例中，终端设备获取到的信道质量测量结果可以包括：N个第一参考信号中的一个第一参考信号的资源索引。举例说明如下，终端设备基于对应了N个赋形波束的N个第一参考信号进行信道质量测量，选择最优的K(N＝>K>＝1)个第一参考信号，上报该K个最优的第一参考信号的资源索引以及对应的波束信道质量信息。该波束信道质量信息可以包括秩指示(rank indication，RI)，信道质量信息(channel quality information，CQI)，参考信号接收功率(reference signal received power，RSRP)，参考信号接收质量(reference signal received quality，RSRQ)中的至少一个。
进一步的，终端设备可以基于对上述N个第一参考信号的信道质量测量选择一个第一参考信号，例如可以是多个第一参考信号中质量最优的参考信号，并上报其选择的第一参考信号的资源索引及此第一参考信号的资源索引对应的信道质量信息。例如，资源索引及对应的信道质量信息的上报的触发可以由物理层下行控制信令动态完成。
示例性的，所选择的第一参考信号的资源索引可以对应了网络设备的一个发射波束，触发上述所选择的第一参考信号的资源索引和或此索引对应的信道质量信息的上报的物理层控制信令同时触发了M(M>＝1)个上行参考信号的发送，该M个上行参考信号的发送用作网络设备的最优接收波束的扫描和选择。在本发明的一些实施例中，该M个上行参考信号可以为采用时分的方式重复发送的M个上行参考信号。该物理层控制信令可以触发了多次上行参考信号的发送，该多次上行参考信号的发送可以是连续的多次发送，也可以是非连续的多次发送，这里不做限定。
205、终端设备接收网络设备发送的物理层控制信令。
其中，该物理层控制信令用于触发终端设备向网络设备发送基于N个第一参考信号的信道质量测量结果，该物理层控制信令还用于指示终端设备向网络设备发送M个第二参考信号，M为大于或等于1的正整数。
本发明的一些实施例中，步骤203网络设备向终端设备发送物理层控制信令之后，终端设备解析该物理层控制信令，终端设备从该物理层控制信令中确定该终端设备向网络设备发送基于N个第一参考信号的信道质量测量结果，终端设备从该物理层控制信令中确定终端设备将要向网络设备发送M个第二参考信号。
206、终端设备向网络设备发送信道质量测量结果。
其中，终端设备在物理层控制信令的触发下，向网络设备发送信道质量测量结果。
207、网络设备接收终端设备发送的信道质量测量结果。
其中，终端设备发送基于N个第一参考信号的信道质量测量结果，网络设备接收终端设备发送的信道质量测量结果，例如，网络设备通过该信道质量测量结果确定终端设备从N个第一参考信号中选择出的一个第一参考信号。
208、终端设备向网络设备发送M个第二参考信号。
其中，终端设备根据物理层控制信令的指示向网络设备发送M个第二参考信号。终端设备发送的M个第二参考信号为M个上行参考信号，其中，物理层控制信令可以触发多次上行参考信号的发送，该多次上行参考信号的发送可以是连续的多次发送，也可以是非连续的多次发送，这里不做限定。
在本发明的一些实施例中，步骤208终端设备向网络设备发送M个第二参考信号，包括：
终端设备采用时分的方式重复的向网络设备发送M个第二参考信号。其中，终端设备可以采用时分的方式发送第二参考信号，即终端设备按照某个发送间隔，重复的向网络设备发送第二参考信号，共向网络设备发送M个第二参考信号。
在本发明的一些实施例中，M个第二参考信号的发送时刻n和信道质量测量结果的发送时刻k满足如下条件：
n＝k+m，
其中，m为大于或等于0的正整数。
举例说明如下，物理层控制信令触发的信道质量测量结果的发送时刻k和M(M>＝1)个上行参考信号的发送时刻n可以相同也可以不同。例如，上述M个上行参考信号的发送时刻n和信道质量测量结果的发送时刻k之间满足如下条件，n＝k+m,m为大于或等于0的正整数。在实际应用中，m的取值不能任意大，否则波束校准的准确性将受影响。上述M个上行参考信号上作用的发射赋形波束与测量得到的接收赋形波束相同，从而保证网络设备侧的最优收发波束校准的准确性。
在本发明的另一些实施例中，上述m的取值也可以为小于0的整数，即M个第二参考信号的发送时刻为在基于N个第一参考信号的信道质量测量结果的发送时刻之前的某个时刻，这里不做具体限定。
在本发明的一些实施例中，m的取值是预定义的；或，m的取值通过高层信令或物理层控制信令指示给终端设备。其中，网络设备和终端设备都可以预先定义m的取值，网络设备也可以通过高层信令或物理层控制信令将m的取值指示给终端设备，其中高层信令具体可以为无线资源控制(radio resource control，RRC)信令或其他高层信令等，对此本发明不做具体的限定。
209、网络设备接收终端设备发送的M个第二参考信号。
示例性的，终端设备发送M个第二参考信号，网络设备接收终端设备发送的M个第二参考信号，例如，网络设备可以接收终端设备周期性发送的M个第二参考信号，也可以接收终端设备半静态发送的M个第二参考信号，或者接收终端设备动态非周期发送的M个第二参考信号，这里不做限定。
在本发明的一些实施例中，步骤209网络设备接收终端设备发送的M个第二参考信号，包括：
网络设备接收终端设备采用时分的方式重复发送的M个第二参考信号。具体的，终端设备重复的发送第二参考信号，共计发M个第二参考信号，网络设备可以采用时分的方式接收第二参考信号，网络设备按照一定的接收间隔重复的接收终端设备发送的第二参考信号，共接收到来自终端设备发送的M个第二参考信号。
在本发明的一些实施例中，网络设备根据接收到的基于N个第一参考信号的信道质量测量结果和基于M个第二参考信号的信道质量测量结果进行波束校准。当发射侧的赋形波束和接收侧的赋形波束存在互易性时，发射侧的最优赋形波束和接收侧的最优赋形波束相同，因此只需通过单侧的最优赋形波束训练和选择即可同时完成另一侧的最优赋形波束选择。其中，用于决定波束互易性是否成立的度量指标可以包括信噪比，波束对应的接收信号功率、波束对应的接收信号质量、波束对应信道状态信息(如CQI等)、波束索引或参考信号索引等中的至少一个。最优接收波束的测量和选择可以基于上述度量指标中的至少一个的取值来决定波束互易性是否成立。其中，波束对应的接收信号功率具体可以为参考信号接收功率(reference signal received power，简称为RSRP)，波束对应的接收信号质量可以为参考信号接收质量(reference signal received quality，简称为RSRQ)等。而波束对应的信道状态信息可以为LTE中的CSI信息，例如信道状态信息参考信号指示符(CSI-RS Index，简称为CRI)、秩指示(Rank Indication，简称为RI)、预编码矩阵指示(Precoding Matrix Indicator，简称为PMI)或CQI等等中的至少一个，或者该第一信道质量信息还可以为无线资源管理(radio resource management，简称为RRM)测量的信道质量信息，例如RSRP、RSRQ等等中的至少一个。本发明实施例对此不作限定。
请参阅图3所示，为本发明实施例提供的网络设备完成波束校准的场景示意图，以网络设备为基站、终端设备为UE为例进行说明，基站侧完成收发波束互易性的校准。基站使用N个不同的发射波束向UE发送N个下行参考信号，UE使用N个相同或不同的接收波束接收N个下行参考信号，UE对N个下行参考信号进行信道质量测量，UE向基站发送波束对应的信道质量测量结果，例如，UE发送的信道质量测量结果，可以包括：N个下行参考信号中的一个下行参考信号的资源索引。基站向UE发送物理层控制信令，UE按照该物理层控制信令的触发信息向基站发送M个上行参考信号，基站对M个上行参考信号进行信道质量的测量，基站根据接收到的基于N个下行参考信号的信道质量测量结果和基于M个上行参考信号的信道质量测量结果进行波束校准。
在本发明的一些实施例中，物理层控制信令触发的信道质量测量结果的发送时刻k和M(M>＝1)个上行参考信号的发送时刻n可以相同也可以不同。例如，上述M个上行参考信号的发送时刻n和信道质量测量结果的发送时刻k之间满足如下条件，n＝k+m,m为大于或等于0的正整数。在实际应用中，m的取值不能任意大，否则波束校准的准确性将受影响。上述M个上行参考信号上作用的发射赋形波束与测量信道质量测量结果时采用的接收赋形波束相同，从而保证网络设备侧的最优收发波束校准的准确性。
进一步可选的，上述m的取值也可以为小于0的整数，即M个上行参考信号的发送时刻为在基于N个下行参考信号的信道质量测量结果的发送时刻之前的某个时刻，这里不做 具体限定。
请参阅如下表1所示，以参考信号具体为探测参考信号(sounding reference signal，SRS)为例，对上述用于触发上行参考信号的发送和信道质量测量结果的发送的物理层控制信令的信息比特取值进行举例说明。
Figure PCTCN2017116912-appb-000001
在本发明的一些实施例中，基站也可通过独立的信令分别触发基于N个下行参考信号的信道质量测量结果的发送和M(M>＝1)个上行参考信号的发送，同理，此时M个上行参考信号上作用的发射赋形波束与信道质量测量结果的接收赋形波束相同，为保证这一点，基站需同时指示M个上行参考信号的发送和基于N个下行参考信号的信道质量测量结果的上报之间的关联或对应关系，例如，上述发送的时刻和上述上报的时刻间的关联关系。具体地为：M个上行参考信号的发送时刻和基于N个下行参考信号的信道质量测量结果的上报时刻间的关联或对应关系。
通过前述的举例说明可知，网络设备向终端设备发送N个第一参考信号之后，网络设备还可以向终端设备发送物理层控制信令，物理层控制信令用于触发终端设备向网络设备发送基于N个第一参考信号的信道质量测量结果，物理层控制信令还用于指示终端设备向网络设备发送M个第二参考信号，因此终端设备可以根据该物理层控制信令发送基于N个第一参考信号的信道质量测量结果，终端设备还可以根据该物理层控制信令发送M个第二参考信号，因此本发明实施例中网络设备和终端设备不需要针对发射赋形波束和接收赋形波束分别进行波束扫描和波束训练，由于网络设备接收有基于N个第一参考信号的信道质量测量结果，和M个第二参考信号，因此只需要网络设备进行波束校准即可，实现网络设备和终端设备的快速波束校准，从而可简化终端设备的波束管理过程，并最大化资源使用效率。

本发明实施例给出一种基站和UE侧的波束校准方法和机制，通过该机制可实现基站端 和UE端的快速准确波束校准，从而可简化基站或UE的波束管理过程，并降低波束扫描，最大化资源使用效率。本发明实施例接下来从UE侧的收发波束互易性校准进行举例说明。
基站可以通过独立的信令分别触发基于N个上行参考信号的信道质量测量结果的指示或通知，和M(M>＝1)个下行参考信号的发送，此时M(M>＝1)个下行参考信号上作用的基站的发射赋形波束与测量得到基于N个上行参考信号的信道质量测量结果的基站接收赋形波束相同，为保证这一点，基站需同时指示M个下行参考信号的发送和基于N个上行参考信号的信道质量测量结果间的关联或对应关系，例如上述发送的时刻和上述上报的时刻间的关联关系。具体地为：M个下行参考信号的发送时刻和基于N个上行参考信号的信道质量测量结果的指示或通知时刻间的关联或对应关系。
UE基于对上述M个下行参考信号的测量得到一个最优的接收波束，通过校准此最优接收波束和基站通知的最优上行发射波束的差值，UE可决定用户侧的收发波束互易性是否成立，同时UE上报此收发波束互易性校准的信息或结果给基站。此收发波束互易性校准的信息或结果，具体可以是1比特的指示消息，该指示消息包括:是或否，也可以是量化后的收发波束差信息，这里不做限定。

本发明实施例给出一种基站和用户侧的波束校准方法和机制，通过该机制可实现基站端和UE端的快速准确波束校准，从而可简化基站或UE的波束管理过程，并降低波束数目较多时波束扫描带来的时延，同时最大化资源使用效率。
通过前述的举例说明可知，终端设备向网络设备发送N个第一参考信号之后，网络设备还可以向终端设备发送物理层控制信令，该物理层控制信令用于触发网络设备向终端设备发送基于N个第一参考信号的信道质量测量结果，该物理层控制信令还用于指示网络设备向终端设备发送M个第二参考信号，因此终端设备可以根据该物理层控制信令发送的基于N个第一参考信号的信道质量测量结果和终端设备基于M个第二参考信号的信道质量测量结果进行波束校准，同理网络设备也可根据上述信息进行相应的波束校准。因此本发明实施例中可实现网络设备和终端设备的快速波束校准，从而可简化网络设备或终端设备的波束管理过程，并最大化资源使用效率。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也 应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
