APPARATUS AND METHOD FOR UPLINK POWER CONTROL OF WIRELESS COMMUNICATIONS

摘要

Systems and methodologies are described that facilitate employing periodi c closed loop power control corrections in a wireless communication environm ent. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each p eriodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control comm ands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance effi ciency of downlink transfer of the periodic power control commands. The peri odic power control commands can be halted upon access terminal uplink resour ces being deallocated. For instance, these resources can be deallocated afte r an inactivity period of the access terminal. Thereafter, the access termin al can initiate random access (e.g., leveraging open loop mechanisms) to res ume periodic power control command transmission.
