Abstract
A cooperative diversity method and apparatus that can minimize interference and maximize an efficiency of a transmission channel between terminals of a cooperative diversity pair, the method including: determining a pair of terminals to be a cooperative diversity pair according to a spectrum sensing result of a cognitive radio (CR); selecting a subchannel through which data is exchanged between the pair of terminals; and transmitting the data between the pair of terminals through the selected subchannel.
Claims40
A cooperative diversity method, the method comprising:
- determining a first terminal and a second terminal to be a first cooperative diversity pair according to a spectrum sensing result of a cognitive radio (CR) for each of the first terminal and the second terminal;
- selecting a subchannel through which data is exchanged between the first terminal and the second terminal;
- and
- transmitting the data between the first terminal and the second terminal through the selected subchannel.
A cooperative diversity apparatus, the apparatus comprising:
- a determiner to determine a first terminal and a second terminal to be a cooperative diversity pair according to a spectrum sensing result of a cognitive radio (CR) for each of the first terminal and the second terminal;
- a selector to select a subchannel through which data is exchanged between the first terminal and the second terminal;
- and
- a transmitter to transmit the data between the first terminal and the second terminal through the selected subchannel.
A cooperative diversity method in a wireless communication system, the method comprising:
- determining a first terminal and a second terminal to be a cooperative diversity pair according to a spectrum sensing result of a cognitive radio (CR) for each of the first terminal and the second terminal.
A cooperative diversity method in a wireless communication system, the method comprising:
- selecting an existing subchannel that is used to transmit and receive data to/from a base station;
- and
- transmitting data between a first terminal and a second terminal of a first cooperative diversity pair through the selected subchannel.
A terminal of a cooperative diversity system, the terminal comprising:
- a determiner to determine another terminal to bind to according to a spectrum sensing result of a cognitive radio (CR) for each of the terminal and the other terminal in order to create a cooperative diversity pair.
A cooperative diversity system comprising:
- a first cooperative diversity pair comprising a first terminal and a second terminal, and selecting a data exchange subchannel through which data of the first terminal and the second terminal is exchanged between the first terminal and the second terminal;
- a base station to which data is transmitted;
- and
- a second cooperative diversity pair that transmits the data to the base station through the data exchange subchannel.
