Abstract: A method (200) for scheduling one or more data packets in a code division multiple access (CDMA) communication system (100) comprises the steps of measuring power by the one or more base sites (122-132) and computing an amount of downlink power resource needed to transmit one or more data packets using measurements made in the one or more of the base sites (122-132); and/or an amount of power resource availability into which one or more data packets can be scheduled. The method also comprises scheduling the one or more data packets based on the computed amount of power. In this manner, a CDMA communication system is able to determine whether sufficient power resource exists in order to schedule one or more data packets, thereby improving scheduling efficiency in scenarios where transmit power in the communication system is highly variable.

Abstract: A base transceiver station 8 includes an adaptive antenna array for radiating a beam of energy 10 in the direction of a mobile station 12. The base transceiver station may estimate the position of the mobile station based upon estimates of both the angular spread of multipath signals received from the mobile and the direction of mobile relative to the base transceiver station. The angular spread and direction may be used to define a spatial sector in which the mobile is believed to reside and a set of downlink weights may be computed so that the antenna array produces a beam with sufficient angular spread to cover such a spatial sector. The downlink weights may be complex weights and may be calculated using discrete spheroidal prolate sequences.

Abstract: A cellular communication system (10), as shown in FIG.1, contains a wideband communication resource utilised to support traffic, including data packets (69), between subscriber units (32-44) and base station equipment (12-20) arranged to administer system access on a cell-by-cell basis. A packet scheduler (70) within infrastructure of the communication system (10) is operationally responsive to a determined level of uplink loading of the wideband communication resource (68) and acts to assess and then selectively notify an availability of data packet resources supported by the wideband communication resource (68) to subscriber units requiring data packet transmissions (69).

Abstract: This invention relates to a packet scheduler and method therefor and in particular a scheduler for a Code Division Multiple Access cellular mobile communication system. In packet base systems it is important to schedule transmissions of packets carefully in order to maximise the capacity of the system. The scheduler has means (235) for maintaining a list of packets for a cluster of cells. A packet is selected from this list and processed in means (237) for calculating an increase in receive power level at a target base station and at other base stations caused by transmitting a packet. The results are fed to means (239) for scheduling packets to a base station so that only packets which do not result in an accumulated receive power level exceeding a maximum receive power level at a base station are scheduled. The scheduler is in particular appropriate for third generation mobile communication systems.

Abstract: A cellular communication system (100) a first Radio Network Controller (107) supporting different communication service types. A first resource controller (203) controls resource allocation for a first communication service type from a first resource partition and a second resource controller (205) controls resource allocation for a second communication service type from a second resource partition. A partition processor (207) partitions a shared resource into at least the first and second resource partition in response to a first admission failure measure for the first communication service type. Optionally, the partition processor (207) may partition the shared resource into at least the first and second resource partition in response to a second admission failure measure for the first communication service type.

Abstract: A method of generating a model of a cellular communication system comprises generating (101) a first cell layout for a first area and then generating (103) a displaced set of cell layouts corresponding to the first cell layout displaced in a different directions such that it borders the first cell layout. A unique mapping exists between the cells of the first set and of the displaced sets. A model location set is generated (105) comprising a plurality of locations within the first area. For each location and for the cells of the first cell layout, the method comprises evaluating (111) an interference characteristic for cells of a cell group containing all the corresponding cells in the different cell layouts. A cell is then selected (113) from the cell group as an interfering cell for the location. The resulting model provides improved wrap around performance while achieving low computational burden for performance evaluation based on the model.
