Abstract:
A method for configuring a radio interface between a mobile station and a base station of a time-division multiplex radio system for a packet data transmission, the method comprising the steps of:defining a transmission from a mobile station to the base stations as an upstream direction; defining a transmission from the base station to a mobile station as a downstream direction; forming a channel by at least one time slot per time-division multiplex frame; effecting the packet data transmission of a plurality of mobile stations via the channel wherein each of the plurality of mobile stations is referenced with an identifier; providing a time slot for signaling in the channel at cyclical intervals; identifying the plurality of mobile stations with abbreviated identifiers for the packet data transmission that are unambiguous in the channel; assigning exclusively, by the base station, at least one time slot for signaling for the upstream direction in a cycle with all time slots for signaling to the mobile station according to a prescribable sequence; and allocating exclusively at least one time slot for signaling for the upstream direction by indicator messages that contain the abbreviated identifiers and time slot designations, wherein the allocation is independent of the packet data transmission from or to the mobile station.
