Title:
CELL EXTENSION IN CELLULAR METHOD TELEPHONE SYSTEM
Document Type and Number:
Japanese Patent JP3363507
Kind Code:
B2
Abstract:
PURPOSE: To obtain the system in which cells are extended without decreasing number of available channels in the cellular method telephone system having channels of the TDMA system.
CONSTITUTION: At a point of time when up-link transmission is started from a mobile station to a base station, an offset is added by a predetermined time from a point of start time of down-link transmission. Number of available channels is unchanged by adjusting the offset depending on a distance of the mobile station from the base station and a transmission delay time is adjusted to send/receive a burst signal in each time slot in this system.
