  • Patent number: 6301478
    Abstract: A method of reducing interference in a cellular radio communication including performing a courtesy handover of a first call to another channel to reduce interference in a second call when the presence of the first call on the same frequency as the second call causes the interference in the second call. Also, a method of setting up a call which permits a retry to a macro cell when a channel of sufficient quality is not found in a micro cell.
    Type: Grant

  • Patent number: 6240125
    Abstract: A radio communications systems which utilize channel hopping such that those channels which have high channel quality for a given connection are used more often than channels having lower channel quality for the same connection. Channel quality, for instance interference, is measured with respect to uplink connections and with respect to downlink connections. The measured interference values are then stored in an interference list for each of the connections in the radio communications system. The interference lists are converted to corresponding weight lists for each of the connections in both uplink and downlink in the base station. A channel which has a high weight value for a given connection will appear more often in corresponding hopsequence lists than a channel which has a lower weight value.
