METHOD AND DEVICE FOR SELECTING TERMINAL CAPABLE OF USING VAMOS
First Claim
1. ) A method of a base station for selecting a terminal capable of supporting voice services over adaptive multiuser channels on one slot (VAMOS), the method comprising:
- determining whether to transmit an adaptive quadrature phase shift keying (A-QPSK) signal to a terminal;
transmitting, if a determination is made to transmit the A-QPSK signal, the A-QPSK signal in an A-QPSK symbol to the terminal;
receiving received signal quality information corresponding to the A-QPSK signal from the terminal; and
determining whether the terminal is a VAMOS-capable terminal based on the received signal quality information.

Abstract
Since a current GSM base station determines whether a terminal can remove interference using only a DARP information report of the terminal, the base station itself needs to determine whether the terminal is a VAMOS-executable terminal that can perform an interference removal function. The base station transmits a signal, together with a signal acting as interference, using an A-QPSK method, in order to determine whether the terminal can use a VAMOS function, and determines whether the terminal can receive an A-QPSK symbol, in consideration of a reception quality signal of a signal transmitted by the terminal.
