Method for performing efficient ranging in a broadband wireless access system

摘要

The present invention relates to a broadband wireless access system; and more specifically to a method and apparatus for performing an efficient ranging procedure by mobile station and a base station, by distinguishing the dedicated ranging from the contention-based random access. A method for performing ranging with a mobile station in a broadband wireless access system according to one embodiment of the present invention comprises: transmitting a first ranging code for requesting ranging to a base station through a first ranging opportunity of a first frame; and receiving a first message including a response to the first ranging code, wherein if the first ranging code is a dedicated ranging code and the response to the first ranging code is “continue”, the first message may further include at least one of a dedicated flag field, a second ranging code, and the information on the second ranging opportunity.

主权项

1. A method of performing ranging with a mobile station (MS) in a broadband wireless access system, the method comprising:
transmitting a first ranging code for requesting ranging to a base station through a first ranging opportunity of a first frame; and receiving a first message including a response to the first ranging code, wherein when the first ranging code is a dedicated ranging code and the response to the first ranging code is “continue”, the first message further includes a dedicated flag field, wherein when the dedicated flag field is set to ‘1’, the first message further includes a second ranging code, and information on a second ranging opportunity, and wherein the second ranging code is a dedicated ranging code which is different from the first ranging code.
