Abstract:
1. A method of controlling transmit power in a call between a first mobile station and a second mobile station in a radio communication system having a first base station in communication with the first mobile station and a second base station in communication with the second mobile station, said method comprising the steps of: communicating through an uplink connection from the first mobile station to the first base station utilizing an uplink power; communicating through a downlink connection from the second base station to the second mobile station utilizing a downlink power; requesting by the first base station, a first Adaptive Multi-Rate (AMR) coded mode for use on the uplink connection, said first AMR coded mode being associated with an uplink Carrier-to-Interference (C/I) ratio; requesting by the second mobile station, a second AMR coded mode for use on the downlink connection, said second AMR coded mode being associated with a downlink C/I ratio; determining the connection having the highest associated C/I ratio; and adjusting either the uplink power or the downlink power to a power level lower than an optimal power level for the connection with the highest associated C/I ratio without changing the AMR coded mode for either the uplink connection or the downlink connection.
