CELL EXTENSION IN A CELLULAR TELEPHONE SYSTEM

摘要

In a cellular telephone system of the type having TDMA channels, the beginnings of the time slots of an upli~~ transmission are offset from the beginnings of the time slots of a downlink transmission by a predetermined amount. By offsetting the beginnings of the time slots, a mobile station is able to operate at an extended distance from the base station without any modifications to the mobile station. Because the mobile stations can operate at a greater distance from the base station without a decrease in the number of available channels, the cellular telephone system is particularly suitable for use in rural areas or coastal areas.
