Method for controlling uplink power in a broadband wireless access system

摘要

The present invention relates to a broadband wireless access system, and more particularly, to a method for efficiently determining power for ranging performed by a terminal on a target base station or a target region during handover or during changing of a region. A method for controlling uplink power for network reentry of a terminal from a first region to a second region in a broadband wireless access system, according to an embodiment of the present invention, comprises the steps of: receiving a media access control (MAC) management message including a power control parameter that is to be applied to the second region from the first region; and performing ranging to the second region by applying the power control parameter.

1. A method of performing uplink power control in an advanced mobile station (AMS) in a wireless access system, the method comprising:
receiving a medium access control management (MAC management) message from a first zone of a base station (BS), the MAC management message containing:
a power control parameter to be applied by the AMS to a second zone of the base station (BS), andan indicator instructing the AMS to synchronize with the second zone of the BS, the power control parameter including an Interference over Thermal value of frequency partition (iotFP) used for AMS resource assignment and an offsetControl value; synchronizing with the second zone of the BS; and transmitting an uplink signal based on the power control parameter through the second zone of the BS, wherein the first zone is a legacy MS support zone and the second zone is an AMS support zone.
