Apparatus and method for supporting hybrid automatic repeat request for anonymously allocated bandwidth in broadband wireless communication system

摘要

An apparatus and method for supporting Hybrid Automatic Repeat reQuest (HARQ) for an anonymously allocated bandwidth in a broadband wireless communication system are provided. The method of a terminal includes obtaining classification information of HARQ support ranging codes from a message received from a base station, to request an anonymously allocated resource, transmitting one of the HARQ support ranging codes, receiving a resource allocation message including HARQ related information and anonymous resource allocation information, and transmitting one of a ranging request message and a bandwidth request header according to the resource allocation information.
