Abstract:
1. A method for determining available communication sub-channels in an OFDM communication system including a first transceiver, a second transceiver and a plurality of communication sub-channels, the method comprising: transmitting, on all sub-channels of a first set of sub-channels selected by the first transceiver from the plurality of communication sub-channels, first availability information regarding the sub-channels of the first set, wherein the first set of sub-channels are the sub-channels available for transmission at the first transceiver; receiving, on all sub-channels of a second set of sub-channels selected by the second transceiver from the plurality of communication sub-channels, second availability information regarding the sub-channels of the second set, wherein the second set of sub-channels are the communication sub-channels available for transmission at the second transceiver; and determining at least one set of common available sub-channels based on the first and second availability information regarding the respective first and second sets of sub-channels by selecting sub-channels common to both the first and second sets.
