SYSTEM AND METHOD FOR DETECTING AND MEASURING UPLINK TRAFFIC IN SIGNAL REPEATING SYSTEMS

摘要

A signal repeating system 14 for a wireless network includes an antenna 16, 18 configured for transceiving signals between a base station 12 and a user equipment device 24. Repeating circuitry is coupled to the antenna 16, 18 and defines an uplink path 62 for signals from the user equipment device 24 to the base station 12 and a downlink path 64 for signals from the base station 12 to the user equipment device 24. The repeating circuitry includes gain circuitry 80 and gain control circuitry 84 that is coupled to the gain circuitry 80. The gain control circuitry 84 is operable for varying the gain of the repeating circuitry according to a waveform 104. Measurement circuitry measures the receive power in the uplink path 62 over time from the user equipment device 24. Processing circuitry 72 cross-correlates the inverted gain variation waveform 104 with the measured receive power for determining the existence of traffic from user equipment devices 24 in the uplink path 62.
