Description

信息调制方法及装置 技术领域
本发明涉及通信领域,具体而言,涉及一种信息调制方法及装置。
背景技术
面对下一代无线接入连续广域覆盖,热点高容量场景需求,现有的正交多址接入技术已经无法很好地支持,一种通过多码字流叠加传输的技术在理论上有更高的容量界,特别是在小区远端用户接近单用户容量极限时,同时能取得近端用户较高的容量。
在正交多址系统下,基站根据下行控制信息(Downlink Control Information,简称为DCI)中的编码调制方式(Modulation and Coding Scheme,简称为MCS)将比特信息编码调制,并将DCI传输告知用户设备(User Equipment,简称为UE)。其中单个码字流的比特信息可以按照二进制相移键控(Binary Phase Shift Keying,简称为BPSK),四相相移键控(Quadrature Phase Shift Keying,简称为QPSK),16正交幅度调制(Quadrature Amplitude Modulation,简称为16QAM),64QAM,256QAM调制方式调制后,
而在非正交多址系统下,多个码字流叠加编码,以两个码字流为例,令一个端用户和一个近端用户配对,两个码字流分别经过编码调制后,经过传输功率比加权,然后叠加,得到合成的传输符号。所述传输功率比是近端用户调制符号的功率占比,即P/(P+P)。
例如,远端QPSK调制符号和近端16QAM调制符号叠加,传输功率比为α,则合成星座是一个64点的星座,如图1a~1c所示。观察合成星座如图1c容易看到,4个星座群散开在4个象限,α越小,散的越开。
然而,现有LTE系统是对每个码字流独立编码调制的,无法支持两个码字流叠加传输。另外,相对正交多址系统,映射到时频资源上的数据 符号并非单个用户的BPSK,QPSK,16QAM,64QAM,256QAM调制符号,而是由多个码字流叠加编码生成的一个不确定的格雷合成星座符号。总之,缺乏一个适用并支持非正交系统的多码字流叠加传输的调制方法。
针对相关技术中,无法支持非正交系统的多码字流叠加传输的问题,尚未提出有效的解决方案。
