  • Patent number: 6122264
    Abstract: A method and system are provided for reducing skew-group blocking in a CDMA wireless system, or similar such blocking in any information transmission system characterized by packet arrivals associated with a given connection occurring at multiples of a fixed timing interval (frame), and where packet arrivals associated with different connections need to be dispersed within that interval. The system assigns competing connections to sub-intervals within a timing interval for such an information transmission systems, and causes a request from an information source for assignment to a specific sub-interval to be acted on pursuant to an evaluation of the impact that the grant of such a request for the specific sub-interval assignment will have on a transmission delay for packets assigned to succeeding sub-intervals in the timing interval.

  • Patent number: 6108321
    Abstract: An interference based dynamic channel assignment scheme for a wireless communication network, for self configuring dynamic channel assignment of a plurality of channels, comprises the steps of: prioritizing a channel list and prioritizing a selected subset of the prioritized channel list. In further enhancements of the present invention, prioritizing a channel list is distributed on a per cell/sector basis so that prioritization is independent of frequency usage information from other cells/sectors and prioritization is based upon uplink and downlink characteristics.
