摘要：The four basic Radio Resource Management (RRM) measurements in Long Term Evolution (LTE) systemare Channel Quality Indicator (CQI), Reference Signal Received Power (RSRP), Reference SignalReceived Quality (RSRQ), and Carrier Received Signal Strength Indicator (RSSI). A measurement ofchannel quality represented by Signal to Interference plus Noise Ratio (SINR) is used for link adaptationalong with packet scheduling, whereas RSRP and RSRQ are needed for making handover decision duringintra-eUTRAN (evolved Universal Terrestrial Random Access Network) handover in LTE. In this paper,some practical measurement results recorded from a live LTE network of Australia using a commercialmeasurement tool namely NEMO Handy are analysed to verify the possible relationships among SINR,RSRP, RSSI and RSRQ as well as to evaluate the effects of SNR on throughput. In addition, the intraeUTRANhandover events occurred during the test period within the test area are studied. The analysisyields some useful information such as: if the SINR is good for a measurement slot, higher throughput isachieved; RSRP and SNR are proportional to each other on average; and lesser is the difference betweenRSSI and RSRP, better is the RSRQ – each of which is consistent with theory. All the measurement resultsare evaluated using computer programs built on MATLAB platform.
