METHOD FOR ALLOCATING BACKHAUL LINK RESOURCES IN RELAY COMMUNICATION SYSTEM AND METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for transmitting and receiving data by allocating resources by dividing backhaul link resources into a plurality of partitions in a relay communication system.SOLUTION: A method according to the present invention includes the steps of: allocating a certain number of initial OFDM symbol transmission periods in a sub-frame of a downlink channel to a control channel that transfers control information of a terminal, wherein data are transmitted from a base station to a relay or the terminal through the downlink channel; dividing resource blocks excluding the control channel of the sub-frame into at least two partitions based on frequency domain; determining whether or not each divided partition is allocated to the relay or the terminal as resources; and allocating data to the determined partition in order to transmit the partition to the relay or the terminal through the downlink channel.
