Abstract:
1. A method for conveying control channel information comprising: assigning, by a processor, a first OFDMA (orthogonal frequency division multiple access) resource region in a secondary downlink control channel to at least one user device of a plurality of user devices when at least one condition is met from the group consisting of: the first OFDMA resource region has not been assigned to any user devices in coverage areas adjacent to the coverage area of the at least one user device that require a downlink transmit power above a first transmit power threshold, the first OFDMA resource region has been assigned to at least one other user device in at least one coverage area adjacent to the coverage area of the at least one user device but the at least one user device only requires a downlink transmit power below a second transmit power threshold, and the first OFDMA resource region corresponds to an OFDMA control region in at least one coverage area adjacent to the coverage area of the at least one user device but the at least one user device only requires a downlink transmit power below a third transmit power threshold; wherein the coverage areas adjacent to the coverage area of the at least one user device comprise the other sectors of the sectored-cell of which the sector serving the at least one user device is a part; transmitting, by a transmitter, primary control channel information via a primary downlink control channel to the plurality of user devices, wherein the primary control channel information comprises an indication that the first OFDMA resource region in the secondary downlink control channel is assigned to the at least one user device; transmitting, by the transmitter, secondary control channel information to the at least one user device in the first OFDMA resource region, wherein the secondary control channel information comprises uplink scheduling information.
