Durga P Malladi, Alkinoos Hector Vayanos: Mitigation of link imbalance in a wireless communication system. Qualcomm Incorporated, Patents Department, November 13, 2003: US20030210668-A1 (1 worldwide citation)

Techniques to mitigate the effects of link imbalance for the uplink between a terminal (or UE) and multiple base stations (or Node Bs). In one aspect, the serving base station (i.e., the one designated to transmit packet data to the terminal) monitors the uplink received SNR for each terminal design ...
