本申请基于申请号为201710313871.2、申请日为2017年05月05日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
本发明涉及通信领域,具体而言,涉及一种上行传输参数的确定方法及配置信息的发送方法、装置。
在长期演进***(Long Term Evolution,简称为LTE)中,仅仅考虑支持一个天线板(Antenna panel)以及比较少的天线元素(Antenna Element)数目,比如2,4 element。上行测量导频(Sounding Referece Signal,简称为SRS)是非预编码的,由element直接映射到端口port。因此上行传输比较简单。
在5G新空口(New Radio,简称为NR)中,上行多输入多输出(Multiple Input Multiple Output,简称为MIMO)传输比LTE中要复杂很多,主要有以下几个原因:
天线配置更加复杂:NR可能支持更多的天线板panel,这些panel可能有不同的方向特性。每个panel支持更多的元素element。最大可以支持到总共32个element。新型用户设备(User Equipment,简称为UE)天线的示意图如图1a、图1b、图2所示。
支持UE端的灵活的预编码选择:在4G中,UE的预编码完全是受到 基站控制的,这种方式使得上行传输没有灵活性。如果继续采用这种方式,如果UE端的天线设计差异化比较大,存在一些用户的天线设计比较复杂,那就很难采用比较简单的码本供用户进行上行传输,因此传统的方案只能用于部分的终端。而对于一些天线特殊的终端,需要采用比较灵活的方式进行传输,避免复杂的码本设计。另外,与4G中不同,终端侧功能更强大以后可以基于互易性进行上行传输,其原理是测量下行导频,获得最佳下行导频及与之对应的下行最佳接收波束,互易性成立的情况下可以互易到上行的发送波束。
除此之外,上行测量导频信号的传输、上行控制信道的传输在也均需要考虑如何设计,但目前,并没有好的方上行的传输设计案能够适应复杂多样的天线配置,充分利用信道互易性,有效的减小导频开销及物理层信令开销,更好的对抗干扰。
在LTE中,上行多天线传输支持的功能比较简单。而在5G NR中,上行MIMO传输比LTE中要复杂很多。
针对上述存在的在复杂多样的天线配置中终端无法确定上行传输参数的问题,相关技术并未提出有效的解决方案。
