Description
本申请涉及通信技术领域,尤其涉及一种CSI报告优先级确定方法及装置。
在高频通信的时候,为了获得更好的通信性能,一般发射功率会较高其中,其中最大辐射功率(Maximum Power Emission,MPE)描述的是用户能允许的最大辐射功率。当终端的发射功率超过了一定限度(例如对人体产生了危害)时,终端设备会尝试降低发射功率。但此时的低功率发射可能不能满足终端设备的性能需求,因此需要终端设备将这个事件进行上报,即发送MPE报告(report)给网络设备。
当MPE报告作为L1信令进行反馈时,需要与其他信道状态信息(Channel State Information,CSI)报告一样,需要重新定义CSI的优先级(priority),但目前并没有关于引入MPE报告之后的CSI优先级的具体方案。
