![]() ![]() RSRP mapping 3GPP TS 36.133 V8.9. LTE technology includes reference signals which a modem uses to assess the state of the connection to a given cell tower in a standard way. In LTE network, UEs need to measure signal strength of its own and neighbor cells constantly, during idle, connected mode or handovers. RSRP levels for usable signal typically range from about -75 dBm close in to an LTE cell site to -120 dBm at the edge of LTE coverage. RSRP levels for usable signal typically range from about -75 dBm close in to an LTE cell site. ![]() ![]() RSRP provides information about signal power from a specific cell while excluding noise and. RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. The mapping of measured quantity is defined in the table below: RSRP mapping 3GPP TS 36.133 V8.9.0 (2010-03) RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. LTE measurement report triggering A1 Serving becomes better than threshold A2 Serving becomes worse than threshold A3 Neighbour becomes offset better than PCell A4 Neighbour becomes better than threshold A5 PCell becomes worse than threshold1 and neighbour becomes better than threshold2 A6 Neighbour becomes offset better than SCell C1 CSI-RS resource becomes better than threshold C2 CSI-RS resource becomes offset better than reference CSI-RS resource B1 Inter RAT neighbour becomes better than threshold B2 PCell becomes worse than threshold1 and inter RAT neighbour becomes better than threshold2 W1 WLAN becomes better than a threshold W2 All WLAN inside WLAN mobility set becomes worse than threshold1 and a WLAN outside WLAN mobility set becomes better than threshold2 W3 All WLAN inside WLAN mobility set becomes worse than a threshold V1 The channel busy ratio is above a threshold V2 The channel busy ratio is below a threshold Event configuration (36.
