Abstract
In a mobile communication system, a relay station (RS) is used for signal exchange with a base station (BS), and includes a first antenna set including at least one antenna, used for signal exchange with the BS, and a second antenna set including at least one antenna, used for signal exchange with a mobile station (MS). The RS selects at least one antenna from the second antenna set for each of the at least one MS, and exchanges a signal with the MS using the selected at least one antenna.
Claims24
A system to transmit/receive a signal, the system comprising:
- a base station (BS);
- at least one mobile station (MS);
- and
- a relay station (RS) comprising:
- a first antenna set including at least one antenna, used for signal exchange with the BS;
- and
- a second antenna set including at least one antenna, used for signal exchange with the MS,
- wherein the RS selects at least one antenna from the second antenna set f or each of the at least one MS, and exchanges a signal with the MS using the selected at least one antenna.
A method to transmit/receive a signal in a relay station (RS) of a mobile communication system, the method comprising:
- when the RS includes a first antenna set including at least one antenna, used for signal exchange with a base station (BS), and a second antenna set including at least one antenna, used for signal exchange with a mobile station (MS), selecting at least one antenna for each MS from the second antenna set to maximize communication capacity with the said MS;
- and
- exchanging a signal with the said MS using the selected at least one antenna.
