Abstract
A method of performing random access in a broadband wireless access system is disclosed. The method includes performing first random access through at least one of a plurality of random access channels, receiving information about the number of access-failed channels among the plurality of random access channels from a base station, when the first random access fails, and performing second random access according to a probability value calculated based on the received information. The present invention increases utilization of random access channels and can effectively schedule an uplink bandwidth, thereby providing an efficient ranging method.
Claims10
A method of performing random access by a mobile station, comprising:
- performing first random access through at least one of a plurality of random access channels;
- receiving information about a number of access-failed channels among the plurality of random access channels from a base station, when the first random access fails;
- and
- performing second random access according to a probability value calculated based on the received information.
A method of transmitting information for random access by a base station, comprising:
- receiving information about first random access from at least one mobile station through a plurality of random access channels;
- and
- transmitting information about a number of access-failed channels from a frame which has performed the first random access to a mobile station which fails in the first random access.
