Abstract
At least one operating condition is determined for a first mobile subscriber station (104) that is operating in an orthogonal frequency division multiple access (OFDMA) network. The first mobile subscriber station (104) is handed off from a base station (102) to a relay station (110). Based upon the at least one operating condition, at least one sub-channel is subsequently assigned from a plurality of sub-channels of a frequency band to the first mobile subscriber station (104) in order to provide an assigned sub-channel resource to the first mobile subscriber station (104). The assigned sub-channel resource can potentially be any of the plurality of sub-channels of the frequency band.
Claims17
A method for facilitating sub-channel assignment in a network comprising:
- in an orthogonal frequency division multiple access (OFDMA) network:
- determining at least one operating condition of a first mobile subscriber station;
- handing off the first mobile subscriber station from a base station to a relay station;
- and
- based upon the at least one operating condition, subsequently assigning at least one sub-channel from a plurality of sub-channels of a frequency band to the first mobile subscriber station to provide an assigned sub-channel resource such that the assigned sub-channel resource can potentially be any of the plurality of sub-channels of the frequency band.
A method for facilitating sub-channel assignment in a network comprising:
- in an orthogonal frequency division multiple access (OFDMA) network:
- receiving at least one operating condition of a mobile subscriber station;
- facilitating a handover of the mobile subscriber station from a base station to a relay station;
- based upon the at least one operating condition, subsequently determining at least one sub-channel from a plurality of sub-channels of a frequency band to the mobile subscriber station such that the determined at least one sub-channel can potentially be any of the plurality of sub-channels on the frequency band;
- and
- dynamically adjusting the determined at least one sub-channel based upon changes in the at least one operating condition.
A base station comprising:
- a receiver for receiving at least one operating condition of a first mobile subscriber station that is operating in an orthogonal frequency division multiple access (OFDMA) network;
- and
- a controller, the controller coupled to the receiver, the controller being programmed to, based upon the at least one operating condition and subsequent to receiving an indication at the receiver that the first mobile subscriber station moved from the base station to a relay station, assign at least one sub-channel from a plurality of sub-channels of a frequency band to the first mobile subscriber station to provide an assigned sub-channel resource such that the assigned sub-channel resource can potentially be any of the plurality of sub-channels on the frequency band.
