本申请基于申请号为201910251510.9、申请日为2019年3月29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以引入方式并入本申请。
本申请涉及无线通信技术领域,具体涉及一种加扰信息处理方法和终端、网络设备。
对于一个终端用户而言,来自于相同小区不同传输点(TRPs)的物理下行共享信道(PDSCH,Physical Downlink Share Channel)的加扰序列是相同的,这将导致来自于不同TRPs的多输入多输出(MIMO,Multiple-Input Multiple-Output)数据流之间存在恒定的干扰。
另外,针对两步随机接入方案,主要将已有的四步随机接入方案中的msg1和msg3统称为一步信息MSG A,在MSG A中终端发送随机接入前导码(preamble)以及物理上行共享信道(PUSCH,Physical Uplink Shared Channel),如何提升不同终端PUSCH碰撞的下的检测或解调性能,目前尚无具体解决方案。
