Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication system capable of assigning channels to every communication request efficiently without adjustments between the cells. SOLUTION: A priority list of a channel group is created for every cell without adjustments between the cells, or for a sector when every cell is sectorized with using a directional antennal, a channel assignment is processed efficiently by selecting channels to be assigned responding to service requests among the highest priority group having usable channels at the time of requests. The list is created based on the various interference measurements. The list tends to stay the same for relatively a long period. But the list should be re- decided periodically to ensure the use of the most suitable list. For example, the list should be changed according to a new configuration exerting effect on interference in a system or according to seasonal vegetational changes.

Abstract: Without intercell coordination on a per communication request basis, channel assignment can be efficiently performed by developing for each cell, or a sector thereof when the cells are sectorized using directional antennas, a priority list of groups of channels, and selecting a channel to be assigned in response to a request for service from the highest priority group which has available channels at the time of the service request. The priority lists are developed based on various interference measurements that are made. The priority lists tend to remain the same for relatively long periods of time. However, periodically, the priority lists should be redetermined to insure that the best lists are being employed. For example the lists may need to be changed due to new construction or to seasonal vegetation changes, which may affect the interference experienced in the system.

Abstract: Without intercell coordination on a per communication request basis, chann el assignment can be efficiently performed by developing for each cell, or a sector thereof when the cells are sectorized using directional antennas, a priority list of groups of channels, and selecting a channel to be assigned in response to a request fo r service from the highest priority group which has available channels at the time of the service request. The priority lists are developed based on various interference measurements that are made. The priority lists tend to remain the same for relatively long periods of time. However, periodically, the priority lists should be redetermined to insure that the best lists are being employed. For example the lists may need to be changed due t o new construction or to seasonal vegetation changes, which may affect the interference experienced in the system. Advantageously, system capacity under peak concentrated load conditions may increase. This advantage is further magnified under fiel d conditions for which the cell shapes are not ideal.
