一种通信方法和终端、网络设备
相关申请的交叉引用
本申请基于申请号为201910251273.6、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。
技术领域
本申请涉及无线通信技术领域,具体涉及一种通信方法和终端、网络设备。
背景技术
第五代移动通信网络(5G)系统中引入了长期演进(LTE,Long Term Evolution)和新无线(NR,New Radio)共存技术,即LTE和NR在同一频谱资源上动态共享。由于NR和LTE设计的不同,NR和LTE的上行载波之间偏差7.5千赫兹(kHz)。因此在LTE和NR网络共存的时候,需要将NR的上行载波偏移7.5kHz,以避免网络侧在接收时发生较大的干扰。
网络侧通过广播发出是否偏移7.5kHz的指示,支持7.5kHz偏移的终端若读取到该指示,则根据指示判断是否在上行传输时进行相应的偏移;但是不支持7.5kHz偏移的终端,则无法读取该指示,若该类终端直接接入共存网络中,则会因为终端未在上行传输时进行相应的偏移而对接收侧产生较大的干扰,从而影响网络侧的接收。
