METHODS AND APPARATUS FOR MITIGATING INTERFERENCE BETWEEN CO-LOCATED COLLABORATING RADIOS

摘要

Methods and apparatus are provided for mitigating interference between spectrally distinct wireless communication networks employing co-located, collaborating radios. A first base station is in a first network and communicates with a first radio within a first frequency range, and a second base station is in a second network and communicates with a second radio in a second frequency range. The first and second radios are geographically co-located, for example, within a public safety vehicle. The first radio determines a maximum level of interference it will accept based on current operational parameters, and communicates a corresponding threshold value to the second radio through a data link. The second radio sends a request to its base station to employ interim scheduling constraints governing uplink transmissions from the second radio, to thereby limit out of band emissions received by the first radio to a range that is less than the threshold interference level.
