Systems and methodologies are described that facilitate employing aperiod ic closed loop power control corrections in a Long Term Evolution (LTE) base d wireless communication environment. An aperiodic power control command can be sent over a downlink to control and/or correct an uplink power level emp loyed by an access terminal. Transmission of the aperiodic power control can be triggered by a measurement (e.g., received power being outside a set mar gin, ). The aperiodic power control command can include a single-bit and/or a multi-bit correction. Further, the access terminal can alter the uplink po wer level employed for subsequent uplink transmissions based upon the aperio dic power control command when received. Additionally, regardless whether th e aperiodic power control command is received at a given time over the downl ink, the access terminal can employ periodic power control commands and an o pen loop power control mechanism to adjust the uplink power level.
