DEVICE AND METHOD FOR CONTENTION BASED ACCESS IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: A device for contention based access in a wireless communication system and a method thereof are provided to efficiently performing reverse direction transmission through a contention based transmission resources. CONSTITUTION: A contention based access control unit(1520) interprets the contention based reverse direction grant received from a base station through a transceiver. The contention based access control unit determines the contention based reverse direction grant availability. The contention based access control unit performs reverse transmission by the determination. A multiplex and demultiplexer(1505) performs logical channel selection process. The multiplex and demultiplexer constitutes packet by combining the data from a plurality of logical channels.
