Description

功率余量计算方法、终端及计算机可读存储介质
相关申请的交叉引用
本申请主张在2017年7月21日在中国提交的中国专利申请No.201710601879.9的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种功率余量计算方法、终端及计算机可读存储介质。
背景技术
在长期演进(Long Term Evolution,LTE)系统中,数据信道的数据不能与控制信道的数据在同一个子帧中同时发送,例如,物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的数据不能与物理上行控制信道(Physical Uplink Control Channel,PUCCH)的数据在同一个子帧中同时发送。终端(User Equipment,UE)向基站报告PUSCH的功率余量(Power Headroom,PH)报告,当基站在某一个子帧中接收到UE发送的功率余量报告,基站可以依据该功率余量报告中所包含的功率余量值,得到UE在PUSCH发送数据时的功率余量,基站在后续调度无线资源的时候,需要参考该功率余量值,防止由于调度过多的资源给UE,而导致的UE在PUSCH发送数据的时候进入功率受限状态。
在传统的LTE系统中,LTE系统中功率余量上报(Power Headroom Report,PHR)进一步分为第一类型PHR(type 1)和第二类型(type 2)PHR,分别针对仅PUSCH(PUSCH only)传输情况,以及PUSCH与PUCCH同时传输情况。上行传输仅支持采用单载波频分多址(Single-carrier Frequency Division Multiple Access,SC-FDMA)一种波形,上行功率控制采用开环+闭环结合的方式。
而第五代(5 Generation,5G)通信系统,或称为新空口(New Radio,NR)系统中,PUSCH支持正交频分多址(Orthogonal Frequency Division  Multiple Access,OFDMA)和SC-FDMA两种波形。那么相关技术中单一波形进行PHR计算和反馈,不能准确反映两种波形混合使用场景下的功率余量计算,不能满足两种波形混合使用的调度需求。
