Abstract: A receiving node has a plurality of receiving antennas in a cooperative communication system with a plurality of relays. The receiving node selects, among a plurality of relays, ones affiliated to a candidate relay group capable of decoding the data of a transmitting node. The receiving node selects, among the relays affiliated to the candidate relay group, ones satisfying the data transmission rate of the transmission node. The receiving node determines the transmission mode of the selected relays as a spatial multiplexing mode or a transmission diversity mode according to the number of the selected relays. [Reference numerals] (S210) Transmission node transmits a transmission symbol;(S220) Each relay determines whether a transmission signal can be decoded;(S230) Each relay reports on the transmission signal's decoding possibility to a reception node;(S240) Reception node selects a minimum number of relays satisfying the transmission rate of the transmission symbol among a group of relay candidates able to decode;(S250) Reception node determines the transmission mode of the selected relays;(S260) Relays selected by the reception node transmits the transmission signal to the reception node in the determined transmission mode

Abstract: PURPOSE: A data transmission method and a terminal therefor of a terminal-relay station system base data communications method of the terminal - relay center system base and terminal therefor are provided to continuously supply a communication in order not to connect of a base station and with a terminal. CONSTITUTION: A channel quality information measuring unit(220) measures a channel quality information of a neighboring terminal based on 'a signal transmitted to a base station' received in a signal receiving unit. A signal transmitting unit(230) includes a channel quality information of the neighboring terminal measured in the channel quality information measuring unit to an uplink slot. The signal transmitting unit transmits the uplink slot to the base station. A controller(240) changes a mode in a terminal mode into a relay station when the signal receiving unit receives a terminal-relay station signal.

Abstract: 본 발명은 단말-중계국 시스템 기반의 데이터 전송 방법 및 이를 위한 단말에 관한 것이다.
음영 지역이나 셀 커버리지 외곽으로 이동하는 단말에 대해 기지국의 셀 내에 위치하는 단말 중 미리 설정된 기준에 부합한 단말을 이동형 중계국인 중계 단말로 설정하여, 음영 지역이나 셀 커버리지 외곽으로 이동한 단말과 기지국과의 통신이 지속적으로 유지될 수 있도록 한다. 따라서, 기지국과 단말 사이의 통신 두절 이후 레인징을 통한 기지국 재 접속 과정에서 발생하는 패킷 손실과 통신 지연이 없기 때문에, 실시간 통신이 가능하다.
