% plotGrid(GRIDSIZE,CSIRSIND) plots the carrier grid of size GRIDSIZE % by populating the grid with CSI-RS symbols of multiple resources % indicated by a cell array of CSI-RS indices CSIRSIND. The purposes of these measurements include: RSRP - Reference Signal Received Power (signal power) ( dBm) (LTE only) RSRQ - Reference Signal Received Quality (signal quality) ( dB) (LTE only) SINR is mostly used in combinaition with other measurements such as RSRP/RSRQ and RSSI. For this measurement, CSI-RS transmitted on antenna port 3000 is used.ĬSI-RSRQ (CSI reference signal received quality): CSI-RSRQ is defined as, N * CSI _ RSRP CSI _ RSSI. CSI-RSSI includes the power from sources, such as co-channel serving and non-serving cells, adjacent channel interference, and thermal noise. This measurement is also performed across N number of resource blocks (measurement bandwidth). LTE RSRP is calculated for useful part of OFDMA symbol and will not consider cyclic prefix. LTE RSRP It is the average power received from a single reference signal resource element. For this measurement, CSI-RS transmitted on antenna port(s) 3000 or 30 is used.ĬSI-RSSI (CSI received signal strength indicator): CSI-RSSI is defined as the linear average of the total received power observed only in the OFDM symbols, in which CSI-RS is present. RSRP is also used to estimate the path loss for power control calculations. It is a measure of the power level that an RF device, such as WiFi or 3G client, is receiving from the radio. This measurement is performed across N number of resource blocks (measurement bandwidth). RSSI is a Radio-Frequency (RF) term and stands for Received Signal Strength Indicator. CSI-RSRP (CSI reference signal received power): CSI-RSRP is defined as the linear average over the power contributions of the resource elements of the antenna ports, which carry CSI-RS configured for RSRP measurements.
