摘要： A method, program, system and apparatus perform dynamic load balancing of coverage areas in a wireless communication network. The dynamic load balancing is performed by evaluating cell congestion based on location information of subscribers in the wireless communication network, collecting network parameters related to the wireless communication network and altering network parameters based on the evaluated cell congestion. After the network parameter is altered, the coverage areas are narrowed. Improvements in cell congestion and quality of server are then determined based on the narrowing of the coverage areas. Altering of the plurality of network parameters and evaluating of the cell congestion are performed continuously until a target quality of service is achieved.

摘要： A method and apparatus for increasing capacity and performance of a base station for a sectorized cellular wireless network is disclosed in which one of the sector antennas is replaced or supplanted by a novel sub-sector antenna that generates a plurality of asymmetrical sub-sector coverage areas that collectively substantially cover the coverage area of the replaced sector antenna. The use of asymmetrical coverage areas permits the total coverage area to closely approximate the symmetrical sector coverage area without creating excessively large sub-sector handover zones or introducing severe degradation in the network performance. This in turn permits the selective replacement of a single sector antenna rather than the wholesale replacement of all sector antennas in a region, leading to lower transitional costs and the ability to provide a focused approach to capacity planning.

摘要： A method and system for generating beamforming weights for a plurality of antenna elements is disclosed. The invention consists of generating broadened nulls in a direction of arrival corresponding to one or more co-channel interference signals. The broadened nulls permit deviations in the measurement of the direction of arrival or variations therein. The increased information content inherent in generating the broadened nulls is accommodated by postulating the existence of a virtual augmented antenna array comprising the antenna elements of the physical array and a plurality of additional virtual elements. The beamforming weights for the elements of the augmented array are truncated down prior to translation to the size of the physical array and are applied to create the desired broadened nulls and thereby improve system performance.

摘要： A method and apparatus for performing adaptive null steering in a slow frequency hopping environment. Where base stations have smart beamforming antenna capability and are interconnected by a base station controller, thus accommodating cyclic and pseudo-random frequency hopping, each base station forwards information on arrival time, frequency and received power of all subscriber communications and co-channel interferers to the controller for correlation. Periodicity information relating to co-channel interferers is returned to the applicable base station, to enable the generation of a null in the direction of arrival of the interferer. Where few base stations have smart beamforming capability, frequency hopping is cyclic only, and each base station generates its own periodicity information. Base stations may also calculate direction of arrival and time of arrival information, and forward this to the controller, if applicable. The invention enhances network capabilities including a subscriber localizing capability hitherto unavailable to network operators.
