dispositivo para adaptaÇço de taxas de transmissço em sistemas de telecomunicaÇÕes entre aparelhos transceptores màveis e/ou fixos

The system includes an air interface whose physical first layer includes at least a first physical channel (DPCCH) and at least a second physical channel (DPDCH) in at least one time slot of the TDMA structure of the telecommunication connection for each telecommunication connection allocated to the first layer. In the first channel a first data field is provided for channel estimation, a second data field is provided for performance regulation and a third data field is provided for transport format data. In the second channel a payload data field is provided. A second layer, the data link layer, and a third layer, the network layer, of the air interface include controllers which access the data in the channels. The distribution of data is changeable in the data fields during a telecommunication connection in the uplink and the downlink connections when the amount of data remains constant in the payload field and the overall amount of data remains constant in the time slot. The distribution can be changed by adaptation the characteristics of the telecommunication connection.
