Wide-band N = full bandwidth (up to 100 Resource Blocks / 20 MHz).Narrow-band N = 62 Sub Carriers (6 Resource Blocks).Of course, it must to be measured over the same bandwidth: In the procedure of handover, the LTE specification provides the flexibility of using RSRP, RSRQ, or both. The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell re-selection decision. RSRQ – Reference Signal Received Quality: Quality considering also RSSI and the number of used Resource Blocks (N) RSRQ = (N * RSRP) / RSSI measured over the same bandwidth. RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal.It is the power of the LTE Reference Signals spread over the full bandwidth (RSSI) and narrow-band (RSRP).Ī minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ RSRP – Reference Signal Received Power: RSRP is a RSSI type of measurement, as follows there are some definition of it and some details as well.The total received power of the carrier RSSI includes the power from co-channel serving & non-serving cells, adjacent channel interference, thermal noise, etc. Total measured over 12-subcarriers including RS from Serving Cell, Traffic in the Serving Cell RSSI – Received Signal Strength Indicator: The carrier RSSI (Receive Strength Signal Indicator) measures the average total received power observed only in OFDM symbols containing reference symbols for antenna port 0 (i.e., OFDM symbol 0 & 4 in a slot) in the measurement bandwidth over N resource blocks.In LTE network, a UE measures two parameters on reference signal: RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality). )/DS(text-decoration: font-size:12.00pt font-family:'Times New Roman')>endobj29 0 1O]Τ�բkS"M�c�KJF��}��&:�J-��cb���?&��11�����?&��cb>����11L� �X�ا!���.In cellular networks, when a mobile moves from cell to cell and performs cell selection/reselection and handover, it has to measure the signal strength/quality of the neighbor cells. If RF support is required, plots will be generated along with RF presence at zoning hearing to answer any questions. Note: To be used when RF support is not required.
