Abstract
A method and apparatus are described including competing by a secondary transmitter with a plurality of secondary nodes in a cognitive radio network to become a relay node for a primary transmitter, the secondary nodes being secondary transmitters and secondary receivers, receiving data transmitted by the primary transmitter in a first time slot if the secondary transmitter was successful in the competition, relaying the received data transmitted by the primary transmitter to a primary receiver in a second time slot, transmitting secondary data to a corresponding secondary receiver in a subslot of the second time slot and transmitting the secondary data to the corresponding secondary receiver in a subslot of the first time slot if the secondary transmitter was not successful in the competition and if the corresponding secondary receiver was successful in the competition.
