Title:
LTEのためのアップリンク電力制御
Document Type and Number:
Japanese Patent JP5362589
Kind Code:
B2
Abstract:
Systems and methodologies are described that facilitate employing aperiodic closed loop power control corrections in a Long Term Evolution (LTE) based wireless communication environment. An aperiodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Transmission of the aperiodic power control can be triggered by a measurement (e.g., received power being outside a set margin, . . . ). The aperiodic power control command can include a single-bit and/or a multi-bit correction. Further, the access terminal can alter the uplink power level employed for subsequent uplink transmissions based upon the aperiodic power control command when received. Additionally, regardless whether the aperiodic power control command is received at a given time over the downlink, the access terminal can employ periodic power control commands and an open loop power control mechanism to adjust the uplink power level.
