METHOD AND APPARATUS FOR RESERVATION OF DATA CHANNEL IN WIRELESS ACCESS SYSTEM

摘要

PURPOSE: A data channel reservation method and a device using the same are provided to efficiently utilize wireless resource by using a new frame structure being used for data channel reservation in high speed communication environment. CONSTITUTION: A transmission module(1250) transmits a request frame to make a data reservation. A reception module(1260) receives acknowledge frame transmitted as a reply to the request frame in a first time period or a second time period. If the acknowledge frame is received in the first time frame, a processor(1220) recognizes that the request frame collides. If the acknowledge frame is received in the second time frame, the processor recognizes that the data channel is successfully reserved. [Reference numerals] (AA) Terminal; (BB) Base station
