Abstract  Abstract

PROBLEM TO BE SOLVED: To facilitate utilizing power control preambles with closed loop power control techniques in a wireless communication environment.

SOLUTION: An access terminal 302 transmits a power control preamble over an uplink in response to an uplink grant (e.g. a first uplink grant after uplink inactivity). The transmission of the power control preamble is explicitly scheduled and/or implicitly scheduled. The power control preamble is transmitted at a power level determined by the access terminal 302 utilizing an open loop power control mechanism. A base station 202 analyzes the power control preamble and generates based on the analysis a power control command to correct the power level employed by the access terminal 302. The access terminal 302 thereafter utilizes the power control command to adjust the power level for uplink data transmission.
