Method and apparatus for power level adjustment in a wireless communication system
First Claim
1. A method for call recovery wherein a mobile terminal'"'"'s transmit power is not controlled by a base station during call recovery, comprising:
- transmitting a pilot strength measurement message from a mobile terminal at a first transmit power level determined by the mobile terminal;
waiting a predetermined time period during which call recovery is not completed; and
transmitting the pilot strength measurement message from the mobile terminal at a second transmit power level determined by the mobile terminal, wherein the second transmit power level is greater than the first transmit power level.

Abstract
A method and apparatus for transmitter re-initialization in a wireless communication system (10). When the communication link between a mobile station (38) and a base station (32) is in trouble, the mobile station and the infrastructure prearrange potential rescue base stations (34). The mobile station (38) disables the transmitter during the rescue process. On recovery the transmit power level of the transmitter is incremented for transmission of the pilot strength measurement message until a hand-off direction message is received. The transmit power level is incremented to a maximum value.
