Abstract  Abstract

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

SOLUTION: An uplink grant can be transferred over a downlink (e.g. a first uplink grant after uplink inactivity) and a power control preamble is sent over an uplink in response to the uplink grant. The power control preamble is transmitted at a power level determined by an access terminal utilizing an open loop power control mechanism. A base station 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. The access terminal thereafter utilizes the power control command to adjust the power level for uplink data transmission.
