Method of supporting extended range in a TDMA system
First Claim
1. A method for allocating timeslots to mobile stations in a cell in a cellular communication system, comprising the steps of:
- determining the distance each mobile station is from a base station in the cell;
offsetting the timing of the uplink burst transmission by an amount equivalent to a given distance offset according to the finite speed of light by up to a predetermined amount to form a virtual distance for each mobile station;
assigning each mobile station a timeslot based upon the virtual distance each mobile station is from the base station, wherein the timeslots within a contiguous group of timeslots are assigned to the mobile stations in the order of the mobile stations increasing virtual distance from the base station and at least one timeslot within said contiguous group is not assigned so as to allow a burst from the mobile stations to slide into the next timeslot.

Abstract
A method for allocating timeslots to mobile stations in a cell in a cellular communication system is disclosed. First, the distance each mobile station is from a base station in the cell is determined. Then each mobile station is assigned a timeslot based upon the distance each mobile station is from the base station, wherein the timeslots within a contiguous group of timeslots are assigned to the mobile stations in the order of the mobile stations increasing distance from the base station and at least one timeslot at the back of the contiguous group is not assigned so as to allow bursts from the mobile stations to slide into the next timeslot.
