1. A method for controlling transmit power at a mobile terminal in a wireless communication system, the method comprising:
receiving a plurality of transmit power control commands, each transmit power control command directing an adjustment in transmit power relative to a prior transmission by the mobile terminal;
adjusting an accumulated power control value in response to a transmit power control command that directs a positive adjustment in transmit power when the mobile terminal is not in a power-limited state;
calculating a transmit power setting for a transmission by the mobile terminal based on the accumulated power control value and a transmission bandwidth allocated for the transmission, wherein the transmission bandwidth allocated for transmissions by the mobile terminal is variable per transmission;
monitoring for an occurrence of one or more predetermined transmit power control reset criteria, wherein the predetermined transmit power control reset criteria include one or more of:
a change in a serving cell for the mobile terminal;
a loss of uplink synchronization; and
elapse of a pre-determined period with no transmissions by the mobile terminal; and
resetting the accumulated power control value to a pre-determined value in response to the occurrence.
