METHOD FOR TRANSMITTING AND RECEIVING DOWNLINK RESOURCE ALLOCATION INFORMATION IN WIRELESS COMMUNICATION SYSTEM CAPABLE OF CHECKING RECEPTION STATUS OF RESOURCE ALLOCATION INFORMATION AND DATA BURST AT BASE STATION AND APPARATUS THEREOF

摘要

PURPOSE: A method for transmitting and receiving downlink resource allocation information in a wireless communication system and an apparatus thereof are provided to check the reception status of resource allocation information and data burst at a base station without changing the structure of an existing uplink HARQ(Hybrid Automatic Retransmission request) feedback channel.;CONSTITUTION: A first signal sequence mapping device(502) outputs the first signal sequence corresponding to the NACK(Negative Acknowledgement) of a corresponding HARQ(Hybrid Automatic Retransmission request) feedback channel. A first modulation and repeating device(504) generates the first modulation symbol sequence by modulating the first signal sequence. A second signal sequence mapping device(510) outputs the zero signal sequence corresponding to the ACK(Acknowledgement) of the corresponding HARQ feedback channel. A second modulation and repeater(512) generates a second modulation symbol sequence by modulating the zero signal sequence. The first and second modulation symbol sequences are multiplexed with a multiplexer(506). A subcarrier mapping device(508) generates the signal of the HARQ feedback channel by mapping a multiplexed modulation symbol sequence.;COPYRIGHT KIPO 2012
