Abstract
A method of performing a Network Coding (NC) by a transmitting node in a wireless communication system, the method comprising receiving uplink packets from a plurality of nodes through respective links, grouping the links into at least one group based on channel quality information, each group satisfying a listed range of channel quality information, performing the NC on downlink data for each group and transmitting each scheduling information shared by each group to the at least one respective group. A method of receiving network-coded data in a wireless communication system comprises transmitting an uplink packet to a transmitting node, receiving scheduling information shared by a group of links from the transmitting node, the group of links satisfying a listed range of channel quality information, receiving downlink data on which NC is performed and decoding the downlink data based on the scheduling information.
