Abstract:
1. A method for radio frequency resource allocation, the method comprising the acts of: determining that radio frequency resources are to be allocated to a plurality of mobile stations in an uplink subframe; determining a signal quality measure for each mobile station of the plurality of mobile stations; and allocating the radio frequency resources in a time alignment within the uplink subframe for mobile stations of the plurality of mobile stations with a determined signal quality measure below a predetermined threshold and then allocating the radio frequency resources within the uplink subframe for mobile stations of the plurality of mobile stations with a determined signal quality measure above the predetermined threshold, wherein at least a first one of the mobile stations with a determined signal quality measure above the predetermined threshold is allocated the radio frequency resources in time alignment in the uplink subframe and at least a second one of the mobile stations with a determined signal quality measure above the predetermined threshold is allocated the radio frequency resources in frequency alignment in the uplink subframe, wherein the radio frequency resources includes a number of frequencies and symbols of the subframe, wherein the plurality of mobile stations communicate with a wireless communication system using orthogonal frequency division multiple access (OFDMA), wherein the mobile stations allocated radio frequency resources in time alignment are allocated more OFDM symbols but less frequencies than the mobile stations allocated radio frequency resources in frequency alignment.
