Abstract
Provided is a relay broadband wireless communication system. The relay broadband wireless communication system includes a plurality of base stations, and one or more relay stations. The base stations perform communication with a relay station placed within a coverage area and generate state information to be provided to the relay station. The one or more relay stations are disposed at a location allowing communication with the plurality of base stations and select one or more serving base stations based on state information received from each of the base stations.
Claims26
A relay wireless communication system comprising:
- a plurality of base stations configured to perform communication with a relay station and generate state information to be provided to the relay station;
- and
- the relay station disposed at a location common to a coverage area of each of the plurality of base stations and configured to select one or more serving base stations based on state information received from each of the base stations.
A relay station in a relay wireless communication system comprising:
- a management unit configured to store state information of a plurality of base stations that are communicable;
- a selection unit configured to select one or more serving base stations based on the state information;
- and
- a communication unit configured to transmit and receive a signal with the one or more serving base stations,
- wherein the relay station is disposed at a location common to a coverage area of each of the plurality of base stations.
A base station in a relay wireless communication system comprising:
- a generation unit configured to generate state information of a base station to select a serving base station of a relay station disposed at a location common to a coverage area of each of a plurality of base stations;
- a communication unit configured to transmit the state information to the relay station;
- and
- a control unit configured to determine whether to accept connection when a connection request is generated from the relay station,
- wherein the control unit provides control to perform communication according to a multiple input multiple output (MIMO) technique by forming a macro MIMO channel with respect to a relay station selecting a plurality of base stations as serving base stations, the macro MIMO channel being formed with a channel of the base station and a channel of at least one of the other base stations.
A method for operating a relay station in a relay wireless communication system, the method comprising:
- receiving, at the relay station, state information of a plurality of base stations being communicable;
- selecting, by the relay station, one or more serving base stations based on the state information;
- and
- performing, by the relay station, communication with the one or more serving base stations,
- wherein the relay station is disposed at a location common to a coverage area of each of the plurality of base stations.
A method for operating a base station in a relay wireless communication system, the method comprising:
- transmitting, by the base station, state information of the base station to a relay station shared by a plurality of base stations to cause the relay station to select a serving base station;
- determining, by the base station, whether to accept connection when a connection request is generated from the relay station;
- and
- performing, by the base station, communication with the relay station when the connection is accepted,
- wherein the performing of the communication comprises performing communication according to a multiple input multiple output (MIMO) technique by forming a macro MIMO channel with respect to the relay station selecting a plurality of base stations as serving base stations, the macro MIMI channel being formed with a channel of the base station and a channel of at least one of other base stations.
