5G(NR)網(wǎng)絡中（下行）功率測量最重要的是RSRP, RSRQ。RSRP/ RSRQ在NR中的基本定義與LTE相同。NR與LTE在功率定義和測量上不同之處如下：
· NR網(wǎng)絡中SINR是最重要的功率評判指標；在RRC消息中SINR是常用測量參數(shù)；
· NR網(wǎng)絡中沒有CRS，RSRP / RSRQ根據(jù)下表其他物理信號進行測定；
Category | Physical Signal for Measurement |
RSRP | SS reference signal received power (SS-RSRP) |
CSI reference signal received power (CSI-RSRP) |
SRS reference signal received power (SRS-RSRP) |
RSRQ | SS reference signal received quality (SS-RSRQ) |
CSI reference signal received quality (CSI-RSRQ) |
SINR | SS signal-to-noise and interference ratio (SS-SINR) |
CSI signal-to-noise and interference ratio (CSI-SINR) |
