Description
本出願は、その内容が参照により本明細書に組み込まれる、2018年10月31日に出願された米国特許仮出願第62/753679号、2018年8月8日に出願された米国特許仮出願第62/716044号、および2018年4月4日に出願された米国特許仮出願第62/652700号の利益を主張する。
PSRS=min{PCMAX,C,P0,PUSCH+α.PLDL+10.log10(MSRS)+δ+PSRS} 式1
ここで、MSRSは、RBの数として表されるSRS送信の帯域幅であり、式の最後のPSRSは、構成可能なオフセットである。したがって、SRS送信電力は、SRS送信の帯域幅および追加の電力オフセットをもつ帯域幅に基づき得る。
