Method and apparatus for multi-radio coexistence

Abstract

A method for multi-radio coexistence receives historical frequency usage information and historical time usage information from a first radio. The method creates a time and frequency mask by extrapolating the historical frequency and time usage information to future times and frequencies when the first radio will be active and uses the time and frequency mask to schedule a second radio to avoid receiving when the first radio will likely be active. A related apparatus has a collocated radio input for receiving timing usage information, a non-collocated radio input for receiving frequency usage information, and a time and frequency mask generator for creating a time and frequency mask using the timing usage information and the frequency usage information. The method and apparatus predicts collocated and non-collocated radio activity in both the time and frequency dimensions to reduce interference among radios operating in overlapping or adjacent frequency bands.
