47、r downlink The gNodeB determines the downlink transmit EPRE. For the purpose of SS-RSRP, SS-RSRQ and SS-SINR measurements, the UE may assume downlink EPRE is constant across the bandwidth. For the purpose of SS-RSRP, SS-RSRQ and SS-SINR measurements, the UE may assume downlink EPRE is constant over

48、SSS carried in different SS/PBCH blocks. For the purpose of SS-RSRP, SS-RSRQ and SS-SINR measurements, the UE may assume that the ratio of SSS EPRE to PBCH DM-RS EPRE is 0 dB. For the purpose of CSI-RSRP, CSI-RSRQ and CSI-SINR measurements, the UE may assume downlink EPRE of a port of CSI-RS resourc

49、e configuration is constant across the configured downlink bandwidth and constant across all configured OFDM symbols. The downlink SS/PBCH SSS EPRE can be derived from the SS/PBCH downlink transmit power given by the parameter SS-PBCH-BlockPower provided by higher layers. The downlink SSS transmit power is defined as the linear average ETSI ETSI TS 138 214 V15.2.0 (2018-07)83GPP TS 38.214 version 15.2.0 Release 15over the power contributions (in W) of all resource elements that carry the SSS within the operating system bandwidth.
