Description

一种被用于无线通信的终端、基站中的方法和装置 技术领域
本发明涉及无线通信系统中的无线信号的传输方法和装置,特别是支持信道编码的无线通信系统中的无线信号的传输方法和装置。
背景技术
传统的LTE(Long Term Evolution,长期演进)系统中不同的DCI(Downlink Control Information,下行控制信息)格式对应不同的编码比特数量,UE(User Equipment,用户设备)根据当前传输模式所对应的所有可能的DCI格式对承载DCI的控制信道进行盲检测。这种控制信道的接收方法会造成DCI所对应的可能比特数量候选项增加时UE侧的盲检测次数也随之增加。
发明内容
发明人通过研究发现,如果根据DCI格式来调整控制信道的星座图案,对不同的DCI格式采用不同的星座图案,可以降低UE侧的盲检测次数。UE可以通过尝试所有可能的星座图案并找出其中具有最大似然概率的一个,来缩小当前控制信道上可能的DCI格式的范围,甚至直接确定当前的控制信道上的DCI格式。
针对上述发现,本发明公开了一种解决方案。需要说明的是,在不冲突的情况下,本申请的UE中的实施例和实施例中的特征可以应用到基站中,反之亦然。在不冲突的情况下,本申请的实施例和实施例中的特征可以任意相互组合。
