Description

传输方式的指示方法及装置 技术领域
本发明涉及通信领域,具体而言,涉及一种传输方式的指示方法及装置。
背景技术
多用户信息传输技术按照接入方式可以分为正交多址接入(Orthogonal Multiple Access,简称为OMA)和非正交多址接入(None Orthogonal Multiple Access,简称为NOMA)。其中,OMA技术中多个用户分别使用相互正交的通信资源进行信息传输,如传统的TDMA、正交CDMA、OFDMA均属于正交多址接入技术的范畴。NOMA技术中多个用户可以在相同的通信资源或非正交的通信资源上进行信息传输。
在正交多址接入技术中,发射机将多个用户的信息分别在相互正交信道上传输,因而在解调时各用户信息之间没有相互干扰,进而分离用户信息较容易。相对地,在非正交多址接入技术中,发射机将多个用户的信息叠加在一起传输,这样,在解调时多用户信息之间是相互干扰的,接收机需要采用多用户检测技术来抑制或消除多用户间干扰,分离出各个用户的信息,例如串行干扰消除(Successive Interference Cancellation,简称为SIC)技术。
下面以两个用户的串行干扰消除(Successive Interference Cancellation,简称为SIC)过程为例进行简单说明,多用户的SIC过程很容易由此推广:先解调译码出用户A的信息(带着用户B的干扰来解调译码A信息)。然后,在解调用户B信息时,需要先将之前解调译码出来的A信息(可能需要重构)减去,再解调出用户B信息。这样用户B信息因为可以没有干扰,所以性能可以存在较大提升。
相关技术中采用非正交多址接入结合SIC技术可以达到多用户信息容量极限,而且能保证边缘用户和中心用户的吞吐量有很好的公平性。目前,长期演进(Long Term Evolution,简称为LTE)通信系统的Release 13版本正在评估NOMA技术的可行性,评估内容包括部署场景、性能评估、多用户叠加传输方案等,NOMA技术有可能被应用在未来无线通信系统中。
要保证实际无线蜂窝通信系统(例如LTE系统Release 10版本)正常运行,下行控制信息(Downlink Control Information,简称为DCI)是必不可少的,DCI包括下行调度分配,上行调度请求,以及针对UE终端的功率控制命令。基站通常通过物理下行控制信道(Physical Downlink Control CHannel,简称为PDCCH)给UE发送固定格式的DCI,并按固定格式的DCI处理信息,将处理的信息通过PD非正交H发给UE,其中DCI的固定格式包括格式0,格式1,格式1A,格式1B,格式1C,格式1D,格式2,格式2A,格式2B,格式2C,格式3,格式3A,格式4。UE根据接收到的DCI信息解调信号。而通过以上对NOMA技术的了解可知,关键在于,基站要知道如何将用户A的信息和用户B的信息叠加处理,并且,用户B要知道解调时如何很好的消除用户A的干扰,
当前实际通信系统(例如LTE系统)的基站能识别的DCI不能用于指示两用户做叠加传输,即基站不知道如何将用户A的信息和用户B的信息叠加处理。
对应的,当前实际通信系统(例如LTE系统)的UE能识别的DCI也不能用于指示用户做SIC消除,即用户B不知道用户A的相关信息,并将用户A的信息消除。
针对相关技术中,NOMA技术的基站不能用于指示两用户做叠加传输,以及不能用于指示用户做SIC消除的问题。
发明内容
