ANTENNA ALLOCATION APPARATUS AND METHOD FOR CELLULAR MOBILE COMMUNICATION SYSTEM
First Claim
1. A method for communicating with a terminal of a base station in a mobile communication system, the method comprising:
- transmitting configuration information on a plurality of antenna ports of reference signals (RSs) which comprise first type antenna ports and second type antenna ports;
receiving status information for at least one antenna port of an RS among the plurality of antenna ports of the RSs;
transmitting at least one indicator indicating at least one selected antenna port of an RS based on the status information; and
communicating with the terminal using the at least one selected antenna port of the RS,wherein the first type antenna ports are for a centralized antenna and the second type antenna ports are for a distributed antenna.

Abstract
Methods and apparatuses are provided for communicating with a terminal of a base station in a mobile communication system. Configuration information on a plurality of antenna ports of reference signals (RSs) which comprise first type antenna ports and second type antenna ports, is transmitted. Status information for at least one antenna port of an RS among the plurality of antenna ports of the RSs, is received. At least one indicator indicating at least one selected antenna port of an RS is transmitted based on the status information. The terminal is communicated with using the at least one selected antenna port of the RS. The first type antenna ports are for a centralized antenna and the second type antenna ports are for a distributed antenna
