Description

信令传输方法、装置及系统 技术领域
本公开涉及通信领域，具体而言，涉及一种信令传输方法、装置及系统。
背景技术
在长期演进(Long Term Evolution，简称为LTE)系统中，由于采用正交频分复用(Orthogonal Frequency Division Multiplexing，简称为OFDM)技术，小区内干扰一般较小，但是由于小区间频率复用，从而导致小区间的干扰较大，成为LTE系统中的主要干扰问题，导致小区边缘性能较差。为了提高小区边缘用户的性能，满足小区边缘频谱效率的需求，长期演进升级(Long Term Evolution-Advanced，简称为LTE-A)系统中引入了协作多点(Coordinated Multi-Point，简称为CoMP)传输技术，CoMP技术通过多个相邻的基站或节点协调，同时为一个小区边缘用户提供服务，以较低小区边缘用户收到邻小区的同频干扰，提高小区边缘用户的服务质量。其中，CoMP技术主要分为三种：联合传输(Joint Transmission，简称为JT)、动态节点选择/动态节点消除(Dynamic point selection/Dynamic point Blanking，简称为DPS/DPB)和协作调度协作波束赋形(Coordinated Scheduling Coordinated beamforming，简称为CSCB)。其中对于JT技术，服务小区和协作小区在相同的时频资源上共同为目标用户提供信号传输，对终端来说，此时干扰信号变为有用信号，从而可以大大提高信号的接收质量。
无线信道条件通常是在不断变化的，为了更好地适应无线信道的变化，UE可以通过下行物理信道状态信息(Channel State Information，简称为CSI)将下行信道质量信息上报给基站，以便基站为UE选择更可靠的调制和编码方案(Modulation and Code Scheme，简称为MCS)，更少打孔(less puncturing)以及选择更好的时频资源，反映下行物理信道状态信息 (Channel State Information，简称为CSI)的三种形式包括：信道质量指示(Channels quality indication，简称为CQI)、预编码矩阵指示(Pre-coding Matrix Indicator，简称为PMI)、秩指示(Rank Indicator，简称为RI)。
LTE中出现的CQI定义繁多，有不同的原则，其中，根据码流个数分为单码字流CQI和双码字流CQI。
另外，在LTE/LTE-A系统中，空间复用下码字与层映射关系如表1所示，尤其当码字流数为2，传输层数为3时，根据表1的规定，则第一个码字流传输1层，第二个码字流传输2层。
目前标准中通过下行控制信令(Downlink Control Information，简称为DCI)通知UE码字/天线端口/加扰ID/层数间的关系，如表2所示，其中单码字下值4/5/6三种情况只能用于重传,如表3所述，其中单码字下值12/13/14三种情况只能用于重传，表3用于全维度多输入多输出(FD-MIMO)。

另外，在LTE/LTE-A系统中，当支持多点传输时，由于数据发送的基站对于终端来说是透明的，并且数据发送的基站可以动态的切换，终端无法准确的获知接收到的数据是由哪一个基站发送的，因此引入了准共位置信息指示(Quasi-Co-Location indicator)的定义和通知信令。
在3GPP TS 36.213的标准中，准共位置信息指示是和物理下行共享信道(Physical Downlink Shared Channel，简称为PDSCH)资源单元映射(Resource Element mapping)的相关信息进行联合通知的，表4为物理下行共享信道资源单元映射和准共位置指示通知信令各状态含义。
表4 物理下行共享信道资源单元映射和准共位置指示通知信令各状态含义
Figure PCTCN2017084249-appb-000006
如表4所示，在物理下行共享信道资源单元映射和准共位置指示通知信令中，使用了2bit的物理层下行控制信令(Downlink Control Information，简称为DCI)来动态的指示4个参数集(set)，每个set包含一组参数，这一组参数包含了以下多个类别的信息：
CRS的配置参数信息包括：端口数目以及频域shift的参数；
多播/组播单频网络(Multimedia Broadcast multicast service Single  Frequency Network，简称为MBSFN)子帧配置参数信息；
零功率(Zero Power，简称为ZP)CSI-RS的参数配置信息；
数据信道起始符号参数的配置信息；
准共位置的非零功率(Non-Zero Power，简称为NZP)CSI-RS信息。
为了是的描述更加直观，这里将上面的参数集合中不同参数的取值总结如下表5。
表5 QCL参数集合不同参数的取值
Figure PCTCN2017084249-appb-000007
可以看出，基站在向终端发送数据的过程中，可以动态的切换发送基站，只需要通过这2bit信令动态的指示上述信息，就可以解决RE mapping问题，以及导频与数据传输准共位置变化的问题。
图1是根据相关技术中非相关JT技术的信息传输系统示意图，如图1所示，在非相关JT技术中，可以有两个基站联合为用户服务，这时服务小区和协作小区分别传输一个码字流至用户，每个单码字流都需要支持大于1层的传输及反馈，目前标准中码字到层映射规则、CQI计算及反馈、 准共位置信息指示(Quasi-Co-Location indicator)并不能较好的支持非相关JT技术，导致了非相关JT技术信息传输的效率很低。
针对相关技术中非相关JT技术的信息传输效率低的问题，目前还没有有效地解决方案。
