On embodiment of the system and method provides asymmetric adaptive modulation which allows uplink and downlink subframes of data to be transmitted between a base station and a CPE with different modulation schemes, thus increasing the efficiency of downlink transmissions while maintaining the stability of uplink transmissions. In systems with multiple CPEs, each CPE and base station pair can independently select their uplink and downlink modulation techniques. The system and method are also adaptive in that they adjust the modulation schemes based on, for example, signal to noise ratio measurements or bit error rate measurements.
A wireless communication system for determining a plurality of uplink modulation schemes and a plurality of downlink modulation schemes for use in a wireless communication system including a base station and a plurality of customer premises equipment (CPE), where each of the plurality of uplink and downlink modulation schemes used by each of the plurality of CPE can be asymmetric, such that the uplink modulation scheme may be different than the downlink modulation scheme, the system comprising:
A wireless communication system for determining an uplink modulation scheme and a downlink modulation scheme for use in a wireless communication system including a base station and at least one customer premises equipment (CPE), wherein the uplink and downlink modulation schemes are independently determined, such that the uplink modulation scheme may be different than the downlink modulation scheme, the system comprising:
A wireless communication system for selecting a plurality of modulation schemes for use with a base station and a plurality of customer premises equipments (CPEs), wherein physical slots in an uplink subframe of data are assigned to the plurality of CPEs by the base station, and wherein the plurality of modulation schemes are used by the plurality of CPEs to modulate data transmitted during the physical slots to the base station, the system comprising:
A wireless communication system for determining a first and second uplink modulation scheme and a first and second downlink modulation scheme for use in a wireless communication system including a base station and a first and second customer premises equipment (CPE), wherein the first uplink and downlink modulation schemes may be different, and the second uplink and downlink modulation schemes may be different, the system comprising:
A wireless communication system for determining a plurality of uplink modulation schemes and a plurality of downlink modulation schemes for use in a wireless communication system including a base station and a plurality of customer premises equipment (CPE), wherein each of the plurality of uplink and downlink modulation schemes used by each of the plurality of CPEs can be asymmetric, such that the uplink modulation scheme may be different than the downlink modulation scheme, the system comprising:
A method for determining a plurality of uplink modulation schemes and a plurality of downlink modulation schemes for use in a wireless communication system which communicates with frames of data and includes a base station and a plurality of customer premises equipment (CPEs), wherein each of the plurality of uplink and downlink modulation schemes used by each of the plurality of CPEs can be asymmetric, such that the uplink modulation scheme may be different than the downlink modulation scheme, the method comprising:
