Assumption is UE has single antenna element per receive path instead of antenna array.įR2 ss-rsrp: Measurement is performed based upon combined signal strength from all antenna elements related to the single receive path. The power is measured in mWatts, power is an energy received during useful part of symbol only, cyclic part not included.įR1 ss-rsrp: Measurement is performed at UE antenna connector. ss-rsrp is average power received from single resource element allocated to SSS. CSI-RS may have different transmit power. The DMRS and SS signals are transmitted with equal power so results can be averaged directly. ss-rsrp is measured by the linear averaging over the power contributions of the resource elements that carry corresponding reference signals taking into account of power scaling of reference signals. ss-rsrp is defined in 3GPP TS 38.215 and 3GPP TS38.133.įor ss-rsrp determination, demodulation reference signals (DMRS) for PBCH with an option of CSI-RS (Channel state information reference signals) is used. The measurement time resources are confined within SS/PBCH block measurement time configuration (SMTC) window duration. It is used for cell selection, cell reselection, power control, mobility procedures and beam management procedures. ss-rsrp is used to compare strengths of the signals from individual cells in 5g networks. These secondary signals are specific to each cell are transmitted using source elements. Ss-rsrp is the linear average over the power contributions of the resource elements received over secondary synchronization signals.
