Abstract:
A method of allocating timeslots in a Time Division Multiple Access (TDMA) telecommunications system comprising steps of:defining a first timeslot for allocation to a first channel; allocating the first timeslot to the first channel to produce a first allocated timeslot; allocating a second timeslot to a second channel to produce a second allocated timeslot such that the second allocated time slot is adjacent in time to the first allocated timeslot; allocating subsequent channels to respective further timeslots, to produce further allocated timeslots, wherein each subsequently allocated channel is allocated to a vacant timeslot which is closest in time to the first timeslot such that each of the further allocated timeslots is adjacent in time to a previously allocated timeslot, thereby forming a contiguous group of timeslots in the time domain; wherein the first timeslot is adaptively defined based on a weighting function of the distribution of mean interference levels of timeslots across the time domain, wherein the weighting function approximates the mean usage of the timeslots.
