INTERFERENCE AVERAGING METHOD WITH DIFFERENT REPETITION CODE PER EACH UE

摘要

A data re-transmission method by interference averaging and an apparatus using the same are provided to reduce interference by making orthogonal code groups for different mobile stations when repetitively transmitting data. A data re-transmission method by interference averaging between terminals in a mobile communication system comprises the following steps of: re-partitions a plurality of terminals into a plurality of subgroups so that terminals belonging to each subgroup can be different according to data re-transmission(S510); re-assigning orthogonal codes and resources to the terminals belonging to each subgroup(S530, S550); and assigning different frequency bands to the terminal whenever data is re-transmitted(S570).
