LTE RSRQ mapping into integer number value from 0 to 34 is mentioned RSRQ mapping from dBm to integer number is carried out first before RSRQ also takes antenna connector of UE as reference point. OFDMA symbols which contain reference symbols transmitted from first antenna port, e.g. RSSI is calculated as a linear average of the total power measured across Where N is number of resource blocks over which RSSI is measured. The equation for LTE RSRQ is defined below: Relative accuracy (between one intra frequency and another inter frequency points) = +/-6dB Relative accuracy (between two intra frequency points) = between +/-2 and +/-3dBĪbsolute Measurement Accuracy (inter-frequency RSRP measurement) = Between +/-6 and +/-8 dB. The same mapping is mentioned in the table below.Ībsolute Measurement Accuracy (intra-frequency RSRP measurement) = Between +/-6 and +/-8 dB. RSRP measurements are mapped to the integer numbers value range from 0 to 97 before they are SIB-5 also provides the similar information to the LTE UE. It also informs UE whether second antenna need to be used for RSRP measurement or not. SIB3 informs the UE of the maximum measurement BW used during intra frequency cell re-selection. LTE RSRP is calculated for useful part of OFDMA symbol and will not consider cyclic prefix.Īntenna connector of UE is considered as reference point.Įither one or both antennas can be used for transmission of reference signal. It is the average power received from a single reference signal resource element. RSRP is also used to estimate the path loss for power control calculations. RSRQ is the short form of Reference Signal Received Quality and it is equivalentīoth LTE RSRP and LTE RSRQ parameters are used for cell selection, cell re-selectionĪnd handover. RSRP is the short form of Reference Signal Received Power and it isĮquivalent to UMTS CPICH Received Signal Code Power (RSCP). This page LTE RSRP vs RSRQ describes difference between RSRP and RSRQ used in LTE.It explains basics of RSRP and RSRQĪnd mentions useful difference between terms.
