    摘要: In a cellular radio system having in each of a plurality of cells at least one base station communicating with mobile stations located within its area, the base stations each transmit a pilot signal to the mobile stations. At least one of the base stations, transmits to the mobile stations by transmitting a pilot signal by using a rather narrow changing antenna beam. The angle of the greatest gain of the antenna beam is controlled in such a way that the antenna beam sweeps the cell area. The mobile stations can use the pilot signal in the identification of a base station, and as an indicator of a need for handover, without the continuous reception of the pilot signal in the subscriber equipment, and without a need to transmit the pilot signal with a higher transmission power than the other signals.

    摘要: In a communication system in which mobile terminals may roam throughout an area with a plurality of base stations with overlapping coverages and wherein the base stations employ multiplexed slots all in the same frequency range, a system and method for allocating slots based on the quality classes of the transmitted traffic wherein certain slots are assigned as owned by some base stations and certain other slots are assigned as shared between base stations. Slots assigned as owned by a base station are assigned as avoided by adjacent base stations. When assigning a slot for communication from a mobile terminal, the number of slot quality measurements that must be made in order to find a slot with interference below an acceptable level is reduced, compared to conventional dynamic slot allocation schemes.

    摘要: Insight and rules are needed for how to handle scheduling in a way meaningful for network operation is explained, such as what transmissions can be delayed for scheduling and which cannot be delayed for scheduling, and how grouped transmissions can be used for interference avoidance. Certain embodiments of the present invention provide a solution to these and other problems. In certain embodiments of the present invention, for example, users are grouped according to criteria which may be indirectly related to interference but are nevertheless different from interference. Thus, for example, certain embodiments of the present invention use expected receive or transmit signal strength or use MCS as grouping criteria.

    摘要: The present invention relates to prioritizing special cells in cell selection in a cellular radio network. In a cellular radio network one or more cells provide a subscriber with special services or tariffs not offered to all subscribers. These cells are called subscriber's special cells. The mobile station measures an average reception level and calculates by means of them cell selection parameters on the basis of which the best cell is selected. In accordance with the invention, when the mobile station detects that the cell is one of cells of a special cell list stored in a memory, it checks first if the cell fulfils a minimum requirement of cell selection on the basis of the measured signal level. If the minimum requirement is fulfilled, the mobile station manipulates the calculation of the cell selection parameter of a special cell to the effect that the selection probability of a special cell is improved with respect to a normal cell. In a preferred embodiment of the invention, the manipulation of the calculation comprises a step of adding a predetermined margin to the measured signal level of a special cell before the cell selection parameter is calculated. This will minimize the possibility that the mobile station would accidentally be camped on a normal cell when it is within the area of a special cell.
