Genetic algorithm aided timeslot scheduling for UTRA TDD CDMA networks
Song Ni, Lajos Hanzo · Electronics Letters · 2005
It is demonstrated that genetic algorithms may be utilised for finding a suboptimum but highly beneficial uplink (UL) or downlink (DL) timeslot (TS) allocation for improving the achievable performance of the third generation UTRA system's time division duplex (TDD) mode. It is demonstrated that this novel GA-assisted UL/DL timeslot scheduling scheme is capable of avoiding the severe BS to BS inter-cell interference potentially inflicted by the UTRA TDD CDMA air interface owing to allowing all TSs to be used both in the UL and DL, hence potentially quadrupling the carried teletraffic and halving the uplink power.
