It includes a set of Drive-Test RSRP Pathloss Measurements with their relative position to the corresponding eNodeB. So RSRP / RSRQ definition in NR is based on other physical signals as shown in the following table. • In time domain, it spans 1/2/4 consecutive symbols which are mapped within last six symbols of the slot. For example, a 4G LTE modem might report an RSSI of -68 dBm, but: RSRP = -102 dBm. The RSRP determine certain processes as handoff and cell selection. RSRQ – Indicates quality of the received signal, and its range is typically -19. The same mapping is mentioned in the table. 1, Fig. -70dBm is excellent, -110dBm is poor or no signal RSRP –. There are commonality and differences in this process between legacy LTE and LTE-BL/CE. A minimum of -20 dB SINR is needed to detect RSRP/RSRQ. 133 V8. This LTE spectrum is more commonly known as Band 71, and it is the lowest frequency (and thus longest range) cellular spectrum in use in the United States -. RSRP (Reference Signal Received Power) is the average power value of received pilot signals (Reference Signal) or received signal level from Base Station. Tap Cell Info. 1. Frequency range sub-6 GHz, mmWave sub-6 GHz, mmWave Subcarrier spacing sub-6 GHz: 30, 60 kHz mmWave: 60, 120 kHz. 72" N and longitude 000° 14׳ 33. 5dB(bad) to -3dB (good). <lte_sinr>: An integer indicating the signal to interference plus noise ratio (SINR). Some studies focus on the downlink LTE cell capacity and the correlation between downlink throughput and the level of the signal measured as Reference Signal Received Power (RSRP) for various. rsrp-ThresholdSSB-SUL RSRP-Range OPTIONAL, --.
