Patent ID: RE40777

Claim:
An air interface for telecommunications systems utilizing wireless telecommunication between at least one of stationary transmitting/receiving units and mobile transmitting/receiving units, comprising: a physical first layer that includes at least one first physical channel and at least one second physical channel in at least one time slot, said at least one time slot being part of a time frame structure of the telecommunications system for each of a telecommunications link that is allocated to said physical first layer, said at least one first physical channel including a first data field for channel estimation utilizing channel estimation data, said at least one first physical channel further including a second data field for power control utilizing power control data, said at least one first physical channel further including a third data field for traffic format channel indication utilizing traffic format channel indication data, said at least one second physical channel includes a user data field with user data; at least one of a second layer and a third layer, said second layer being responsible for data security, said third layer being responsible for switching; a control in at least one of said second layer and said third layer that accesses the at least one first physical channel and the at least one second physical channel, said control controlling distribution of the channel estimation data and the power control data and the traffic format channel indication data among the first data field and the second data field and the third data field so as to be varied in at least one of an uplink and a downlink telecommunication direction, said distribution being adapted to the characteristics of said telecommunications link while amount of data in the user data field remains constant and a total amount of data per said at least one time slot also remains constant.
