Patent ID: 7167482

Claim:
A method for configuring a radio interface between a mobile station and a base station of a time-division multiplex mobile radio system for packet data transmission, the method comprising: defining a transmission from a mobile station to the base station as an uplink direction; defining a transmission from the base station to a mobile station as a downlink direction; forming a channel by at least one time slot per time-division multiplex frame, wherein the packet data transmission from a plurality of mobile stations takes place via the channel; combining frames to form a macroframe; providing a time slot for signaling at cyclic intervals in the channel; and allocating, by the base station, one time slot exclusively for signaling in the uplink direction from a respective mobile station in accordance with a predeterminable sequence of the mobile stations, where even if the respective mobile station does not transmit any packet data for the duration of a current and next macroframe, the respective mobile station may transmit in the allocated time slot for signaling.
