Description

上行参考信号的发送方法、装置及系统，基站和终端 技术领域
本公开涉及通信领域，具体而言，涉及一种上行参考信号的发送方法、装置及系统，基站和终端。
背景技术
在相关技术中，在长期演进(Long Term Evolution，简称为LTE)中，物理下行控制信道(Physical Downlink Control Channel，简称为PDCCH)用于承载上、下行调度信息，以及上行功率控制信息。下行控制信息(Downlink Control Information，简称为DCI)格式(format)分为DCI format0、1、1A、1B、1C、1D、2、2A、3，3A等，后面演进至LTE-A Release12(LTE-A版本12)中又增加了DCI format 2B、2C、2D以支持多种不同的应用和传输模式。基站(e-Node-B，简称为eNB)可以通过下行控制信息配置终端设备(User Equipment，简称为UE)，或者终端设备接受高层(higher layers)的配置，也称为通过高层信令来配置UE。
测量参考信号(Sounding Reference Signal，简称为SRS)是一种终端设备与基站间用来测量无线信道信息(Channel State Information，简称为CSI)的信号。在长期演进系统中，UE按照eNB指示的频带、频域位置、序列循环移位、周期和子帧偏置等参数，定时在发送子帧的最后一个数据符号上发送上行SRS。eNB根据接收到的SRS判断UE上行的CSI，并根据得到的CSI进行频域选择调度、闭环功率控制等操作。
在现有的LTE-A Release 10(LTE-A版本10)的研究中提出：在上行通信中，应该使用非预编码的SRS，即：天线专有的SRS，而对PUSCH的用于解调的参考信号(De Modulation Reference Signal，简称为DMRS)则进行预编码。基站通过接收非预编码的SRS，可估计出上行的原始CSI，而经过了预编码的DMRS则不能使基站估计出上行原始的CSI。此时，当UE使用多天线发送非预编码的SRS时，每个UE所需要的SRS资源都会 增加，也就造成了系统内可以同时复用的UE数量下降。UE可通过高层信令(也称为通过trigger type 0触发)或下行控制信息(也称为通过trigger type 1触发)这两种触发方式发送SRS，基于高层信令触发的为周期SRS，基于下行控制信息触发的为非周期SRS。在LTE-A Release 10中增加了非周期发送SRS的方式，一定程度上改善了SRS资源的利用率，提高资源调度的灵活性。
随着通信技术的发展，数据业务需求量不断增加，可用的低频载波也已经非常稀缺，由此，基于还未充分利用的高频(30～300GHz)载波通信成为解决未来高速数据通信的重要通信手段之一。高频载波通信的可用带宽很大，可以提供有效的高速数据通信。但是，高频载波通信面临的一个很大的技术挑战就是：相对低频信号，高频信号在空间的衰落非常大，虽然会导致高频信号在室外的通信出现了空间的衰落损耗问题，但是由于其波长的减小，通常可以使用更多的天线，从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是，当天线数增多时，由于此时需要每个天线都有一套射频链路，基于数字波束成型也带来了增加成本和功率损耗的问题。因此，目前的研究中比较倾向于混合波束赋形，即射频波束和数字波束共同形成最终的波束。
在新的无线接入技术(New Radio Access Technology)的研究中，高频通信系统除了基站会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落，用户终端同样也会配置大量的天线形成上行传输波束，此时SRS的发送也将会采用波束的形式发送。如何信令指示SRS的波束发送，是一个待解决的问题。
针对相关技术中，发送上行参考信号的技术方案不完善的问题，目前还没有有效的解决方案。

下面结合本公开的具体实施例进行详细说明。
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合本公开的具体实施例对本公开实施例的实现进行详细阐述。
在本申请文件中涉及的上行参考信号可以包括：测量参考信号、上行解调参考信号。
基站可以包括：宏基站、微基站、发送接收节点、传输节点。
具体实施例一
基站通过高层信令或下行控制信令指示用户终端在一个或多个发送方式上发送上行参考信号，其中，该发送方式至少包括以下之一：发送波束、发送天线、发送扇区、发端预编码、通过天线端口指示的方式、通过天线权重矢量指示的方式、通过天线权重矩阵指示的方式、空分复用方式、频域/时域传输分集方式、发送序列、发送的层数、传输模式、调制编码方式、通过参考信号指示的方式。
进一步地，该下行控制信令携带的信息包括：用于指示用户终端根据下行的接收方式确定上行参考信号的发送方式的信息，其中，该接收方式包括：接收波束、接收天线、接收扇区。
进一步地，该用户终端根据下行的接收方式确定上行参考信号的发送方式，包括：将该接收方式的方向作为发送该上行参考信号的基准发送方向，该用户终端依次从基准方向的左边第N个发送方式至右边第N个发送方式上发送上行参考信号，或者，该用户终端依次从基准方向的邻近2N+1个发送方式上发送上行参考信号，其中，N为1至32之间的整数，包括1和32。
例如，基站通过下行控制信令指示用户终端根据下行的接收方式确定上行参考信号的发送方式，假定用户终端接收下行信号使用的接收波束为接收波束5，信道互易或部分信道互易对应的上行发送波束为发送波束5，假定基站和用户终端预定义N的值为2，发送波束根据邻近关系的编号顺序为：发送波束1、发送波束2、发送波束3、发送波束4、发送波束5、发送波束6、发送波束7、发送波束8，则用户终端依次从发送波束3、发送波束4、发送波束5、发送波束6、发送波束7上发送上行参考信号。因此基站通过此方式可实现上行发送波束的扫描。
需要说明的是，在本申请文件中，发送波束，发送天线，发送扇区的含义分别是：以波束的形式发送，以天线的形式发送，以扇区的形式发送。同样，接收波束，接收天线，接收扇区的含义分别是：以波束的形式接收，以天线的形式接收，以扇区的形式接收。
具体实施例二
基站通过下行控制信令指示用户终端在一个发送方式还是多个发送方式上发送上行参考信号。例如，当下行控制信令所携带的指示信息位取值为1时，则表示指示用户终端在相同的发送波束上发送多次的上行参考信号，当下行控制信令所携带的指示信息位取值为0时，则表示指示用户终端在多个发送波束上依次发送的上行参考信号。或者，当下行控制信令所携带的指示信息位取值为0时，则表示指示用户终端在相同的发送波束上发送多次的上行参考信号，当下行控制信令所携带的指示信息位取值为1时，则表示指示用户终端在多个发送波束上依次发送的上行参考信号。
进一步地，该多个发送波束的数量可以由用户终端根据自身的发送天线配置或能力来确定，或者由基站通过信令来配置，或者由基站通过信令激活和去激活的方式来确定发送波束的数量。
具体实施例三
由于UE的天线配置和发送能力存在多样性，不同UE所能支持的上行发送波束数量也会存在很大差异。假定基站不确定UE的天线配置和能力等级，则基站很难直接通过信令指示来确定上行波束扫描的数量以及信令指示最佳的发送波束ID或发送波束索引，这时可考虑用隐含的方式来指示。比如UE上行发送SRS时，在不同的发送波束上发送使用不同的循环移位和/或发送梳的SRS序列，基站可通过对接收到的SRS进行相关检测，确定相关峰值最高的循环移位和/或发送梳，再通过信令向UE指示循 环移位和/或发送梳的值，则UE端就可以通过循环移位和/或发送梳的值隐含得到最佳的上行发射波束。
具体实施例四
基站直接通过下行控制信令指示所触发的上行参考信号类型；
或者，基站通过高层信令为用户终端配置多套的上行参考信号参数集，其中，参数集中包括上行参考信号的类型参数，基站通过下行控制信令指示用户终端使用这多套参数中的1套用于发送上行参考信号，从而实现动态触发上行参考信号类型的功能。
进一步第，该上行参考信号类型至少包括以下之一：用于进行上行波束扫描的参考信号、用于进行上行波束跟踪的上行参考信号、在特定发送方式上发送的上行参考信号或发送方式专有的参考信号、用于进行上行粗波束扫描的参考信号、用于进行上行细波束扫描的参考信号。
例如，基站通过高层信令为用户终端配置了3套SRS的参数集，分别为参数集1、参数集2、参数集3，其中，参数集1中上行参考信号类型为用于进行上行波束扫描的参考信号，参数集2中上行参考信号类型为用于进行上行波束跟踪的上行参考信号，参数集3中上行参考信号类型为在特定发送方式上发送的上行参考信号，则基站可通过表1所示的下行控制信令状态动态触发SRS的类型。表1是根据本公开具体实施例四的下行控制信令的SRS请求域描述表，如表1所示，

SRS请求域 描述
的取值  
00 不触发SRS
01 触发SRS且使用SRS参数集1
10 触发SRS且使用SRS参数集2
11 触发SRS且使用SRS参数集3
具体实施例五
基站和用户终端双方预定义发送上行参考信号所使用的发送方式，包括：基站通过下行控制信令触发用户终端发送上行参考信号，其中，该下行控制信令携带有下行发送波束ID或下行发送波束索引号，用户终端根据该下行发送波束ID或下行发送波束索引号确定发送上行参考信号的上行发送波束ID或上行发送波束索引号。
