Method of transmitting data information in a mobile, cellular radio communication system

Claim 1

Method in transmitting data information in a mobile, cellular, radio communication system, which transmits the information according to the time-­division multiple access (TDMA) principle, and with a given bit frequency in frames (R1, R2...) each containing time slots (CH1, CH2...) carrying said data information for the calls, and where the utilisation of capacity in a given cell (C2) in the system is such that the number of slots in every frame is greater than the greatest number of calls in progress between the mobile stations (M1) in the cell (C2) and a base station (B2) associated with the cell (C2), characterized in that in the communication direction mobile-base station (B2) m ( m >1) slots are allotted to a mobile within the cell (C2) and in each frame, one slot of said slots constituting the slot normally allotted to the mobile, and at least one of the (m-1) remaining slots in the frame being utilised in response to the distance of the mobile from the base station (B2) by the bit frequency of the data information from the mobile (MS) to the base station (BS) being reduced to a new value (f r ), which is responsive to the number m of allotted slots.
