Abstract:
1. A base station comprising: a transceiver providing communication with a plurality of mobile stations; a memory storing a first database of threshold CINR (carrier to interference noise ratio) values based on a threshold CINR/RSSI (carrier to interference noise ratio/received signal strength indication) function curve; and a processor coupled to the transceiver and the memory, the processor implementing a scheduling module; wherein when the transceiver receives a request to connect from a first mobile station of the plurality of mobile stations, the scheduling module obtains an actual CINR value and an actual RSSI value for the first mobile station; wherein the scheduling module compares the actual CINR value with a threshold CINR value retrieved from the first database based on the actual RSSI value; wherein when the actual CINR value is greater than the threshold CINR value for the actual RSSI value, the scheduling module assigns the mobile station one or more subcarriers from a fully used zone of subcarriers; and wherein when the actual CINR value is not greater than the threshold CINR value for the actual RSSI value, the scheduling module assigns the mobile station one or more subcarriers from a segmented zone of subcarriers.
