Communication system and method for single-point transmission and reception and coordinated multi-point transmission and reception

Abstract

A communication system and method for single-point transmission and reception and coordinated multi-point transmission and reception are provided. The system and method include determining information associated with a channel status of a target terminal. The system and method also include selecting, with respect to the target terminal, one of single-point transmission and reception and coordinated multi-point transmission and reception based on the information associated with the channel status of the target terminal.

What is claimed is: 
     
         1 . A method for a handover, the method comprising:
 determining points in time at which signals transmitted from a plurality of base stations are received at a terminal; and   selecting a serving base station from the plurality of base stations based on the determined points in time.   
     
     
         2 . The method of  claim 1 , further comprising determining propagation delays of the signals transmitted from the plurality of base stations based on the determined received points in time;
 wherein the selecting of a serving base station further comprises selecting the serving base station from the plurality of base stations based on the propagation delays.   
     
     
         3 . The method of  claim 1 , wherein the selecting of a serving base station further comprises selecting as the serving base station a base station that transmitted a signal that was received earliest at the terminal among the signals transmitted from the plurality of base stations. 
     
     
         4 . A communication apparatus comprising:
 a recognition unit configured to determine points in time at which signals transmitted from a plurality of base stations are received at a terminal; and   a selecting unit configured to select a serving base station from the plurality of base stations based on the determined points in time.
