A method and apparatus for receiving data using multiple antennas in a communication system are provided. A received signal-combining scheme is determined according to the strength of an interference signal included in the signals received from the antennas. The signals received from the antennas are combined according to the determined received signal-combining scheme. In this manner, the method and apparatus adaptively use a received data-combining scheme according to the channel condition, thereby ensuring optimal reception performance.

Method and apparatus for receiving data using multiple antennas in a communication system

A method and an apparatus for improving power efficiency of a User Equipment (UE) by using channel state information between a Node B and the UE and power headroom information of the UE in a mobile communication system. The method includes acquiring power information in relation to transmission powers of UEs; arranging the UEs in a sequence based on the power information; determining, for each UE according to the arranged sequence, whether a first reception power of a Node B exceeds a second reception power; allocating a resource area including partially consecutive sub-carriers to at least one corresponding UE when the first reception power exceeds the second reception power; allocating a resource area including entirely consecutive sub-carriers to at least one corresponding UE when the first reception power does not exceed the second reception power; and transmitting resource allocation information indicating the allocated resource area to the each UE.
