METHOD FOR CONFIGURING SUBCHANNELS IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

PURPOSE: A method and an apparatus for configuring sub channels in a wireless communication system are provided to improve efficiency by constituting the sub channels for uplink data transmission. CONSTITUTION: Uplink transmission resources are classified into a PUSC(Partial Usage of SubChannel) tile unit of 4 subcarriers×3 symbols. Sub channels comprise 6 PUSC tile units according to a predetermined rule. The preset number of consecutive sub channels among the sub channels is allocated to the sub channel for a legacy system. The rest of the sub channels are allocated to the sub channel for a wireless telecommunication system. Sub channel rotation for a slot unit consisting of 3 symbols is activated on the sub channel for the legacy system. The sub channel rotation of the slot unit is performed based on the number of the sub channels for the legacy system.
