    Abstract: In a radio communication system in a mobile to mobile call with one good (AMR 102 ) and bad (AMR 515 ) radio link, the good radio (AMR 102 ) link is forced by the poor (AMR 515 ) link to use a more robust AMR coded mode (AMR 515 ) and thereby using excessive power ( 232 ). A capacity loss in such system is avoided by adjusting the power level ( 212 ) for the connection with the good link (AMR 102 ).

    Abstract: In a digital cellular radio communication system, a base station selects a speech/channel encoding mode based on measurements of the local radio environment. The mobile station determines the selected mode by trial decoding possible modes to find the most probable mode and uses the same mode for transmission to the base station on the return link. The coding gain/loss obtained by this mode switching may be used to adjust the output power of transmitters, thereby reducing the overall interference level in the system.
