Abstract
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.
