Abstract: Radio links support signals, representing data blocks composed of symbols, transmitted between base stations and mobile stations by applying a transmission errors protection scheme selected from several specified protection schemes. Some at least of said stations communicate to a control unit measurement values relating to errors observed in the reception of symbols transmitted, and the control unit consults at least one lookup table to adaptively select the protection scheme applied to each radio link as a function of the measurement values communicated in relation to said link. For at least one of the protection schemes, statistical parameters relating to errors observed in the reception of blocks transmitted by applying said protection scheme are estimated. The estimated statistical parameters are processed so as to update the lookup table.

Abstract: A cellular mobile radio network includes base stations, a packet control unit capable of communicating with a radio terminal via two or more base stations, and routing means for routing data between a remote unit and the packet control unit. The data transmitted by the remote unit to the terminal are stored temporarily in the packet control unit. The remote unit is adapted to receive from the terminal acknowledgments relating to transmitted data segments and to retransmit data segments that have not been acknowledged on the expiry of a retransmission time depending on the received acknowledgments. Data segments are transmitted from the remote unit to the terminal via a first base station connected to the packet control unit. In response to a request for communication transfer to a second base station connected to the packet control unit, only a portion of the data stored temporarily in the packet control unit is retransmitted to the terminal via the second base station.
