Abstract

This paper proposes a dynamic channel allocation strategy which takes advantage of switching point (SP) positioning, which is one of the features in the time division duplex (TDD) transmission mode. A switching point is where the transmission changes direction from downlink to uplink and vice-versa. By placing the switching point within a transmission frame dynamically, a TDD system can provide flexible uplink and downlink capacity to accommodate varying asymmetric traffic in each direction. The proposed algorithm is evaluated by means of simulation and the results are compared to that of a system configured with other allocation algorithms.
