OPTIMISED OPERATIONS FOR RESEARCH IN ADJACENT CHANNELS AND FOR ALLOCATING OPTIMISED TIME SLOTS FOR MOBILE STATIONS TRANSMITTING IN A PLURALITY OF TIME SLOTS

摘要

The present invention relates to a system and a method for transmitting data packets between at least one base station (1,9) and at least one mobile station (5) in a mobile radio-telephone system. The data packets are each time transmitted in time frames comprising a fixed number of time slots, and the mobile station is capable of transmitting five data packets in a plurality of successive time slots. While the mobile station (5) communicates with a base station (1) at a given moment, an emitting unit (3) of said base station (1) either sends control data packets or sends no data packet during predetermined time slots. This method is characterised in that a reception unit (6) in the mobile station (5) is provided each time with a time interval which is longer than a predetermined time frame for receiving timing data packets and/or for measuring the signal levels of adjacent base stations (9).
