Abstract:
1. A method for optimizing exchanges of acknowledgement signals between a mobile equipment in asynchronous communication with a plurality of base stations of a cellular telecommunication network by synchronizing said mobile equipment with the cellular telecommunication network, said mobile equipment sends data to said base stations and each base station is configured to return a positive acknowledgement ACK to the mobile equipment if the base station receives the data transmitted by the mobile equipment correctly, or a negative acknowledgement NACK if the data transmitted by the mobile equipment was incorrectly received by said base stations, the method comprising the steps of: estimating quality of downlink communication between each base station and the mobile equipment on at least one channel, such that if at least one base station returns an acknowledgement to the mobile equipment, said mobile equipment only requests a negative acknowledgement NACK from said base stations for all subsequent data transmission while said estimated quality is higher than a preset value; re-transmitting said data only if the estimated quality of the at least one channel is less than the preset value for each base station or if the estimated quality of at least one channel from at least one base station is less than the preset value and all the other base stations send a negative acknowledgement NACK to the mobile equipment.
