APPARATUS AND METHOD FOR ALLOCATING A HARQ(HYBRID AUTOMATIC REQUEST) CHANNEL IDENTIFIER IN A WIRELESS ACCESS SYSTEM CAPABLE OF ALLOCATING ACID(INITIAL HARQ CHANNEL IDENTIFIER) VALUES ALLOCATED THROUGH FIXING RESOURCE ALLOCATION TO SERVICE FLOW

摘要

PURPOSE: An apparatus and method for allocating a HARQ(Hybrid Automatic Request) channel identifier in a wireless access system are provided to efficiently use uplink resources of a terminal by mapping only initial ACID(Initial HARQ Channel Identifier) values on specific service flow.;CONSTITUTION: A base station transmits control information indicating an initial ACID(Initial HARQ Channel Identifier) value to a terminal(S210). The base station transmits a preset allocation A map information element(PA A-MAP IE) to the terminal(S220). The terminal compares the initial ACID value mapped on specific service flow and the initial ACID value included in the PA A-MAP IE(S230). The terminal uses all of allocated ACID values through the PA A-MAP IE for the specific service flow(S240). The terminal uses the rest of ACID values excluding the initial ACID value mapped on the specific service flow for the other service flow(S250). The initial ACID value allocated for the specific service flow is used for the other service flow(S270).;COPYRIGHT KIPO 2012
