method for providing services to packet radio resources shared by more users in a system of type tdd - cdma

摘要

According to the invention, an identifier, here described as User - State Flag (U-SF), is assigned to a pool of radio resources assigned to a mobile station, and possibly shared with other mobile stations, thus enabling the network to address to that specific (uplink or downlink) resource pool of that specific mobile station. Always according to the invention, all the time slots of the radio frame are assigned a state index, here described as Time Slot - State Flag (TS-SF), enabling the network to indicate the use condition of the relevant time slot to a specific mobile station, for instance addressed through the above-mentioned U-SF field. If the addressed mobile station has resources assigned on time slot "X" and the network enables the use of such time slot, the above-mentioned mobile station could respectively transmit, in the agreed time slot, on the whole resource pool marked with the U-SF state flag that are located on time slot "x" if said time slot has uplink direction, or is sure not to receive, for the agreed time slot, from the whole resource pool marked with the U-SF state flag that are located on time slot "x" if said time slot has downlink direction. Finally, as an integration of the points indicated above, the network can signal, for each time slot enabling in transmission, the power level expected in uplink direction by the addressed mobile station.
