Air interface for telecommunications systems with cordless telecommunications between mobile and/or stationary transmitting receiving devices

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 a 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, with a total amount of data per time slot remaining constant, at least one of first data in data fields being allocated to the second channel and the user data in the user data field being allocated to the first channel, said first data including the power estimation data and the power control data and the traffic format channel indication data.

An air interface for wireless telecommunications systems between devices comprising:

• a first layer including at least one first physical channel and at least one second physical channel, wherein at least one time slot of a time frame structure of the telecommunications system is allocated to the first layer for each telecommunications link, and wherein the second channel includes a user data field with user data;
• a first data field, contained within a channel field for channel estimation using channel estimation data;
• a second data field for power control using power control data;
• a third data field for traffic format channel indication using traffic format channel indication data;
• a second layer which is responsible for data security and/or a third layer which is responsible for switching of the air interface, each second and/or third layer containing control means that access the physical channels in such a way that a distribution of the data in the data fields during the telecommunications link can be varied adaptively in the uplink and/or downlink telecommunications directions.
