Claim Text:
1. A method for reducing interference in collocated radios, comprising: identifying a repeating Bluetooth transmit/receive (Tx/Rx) pattern for a multi-radio mobile communication device having a Bluetooth radio configured to communicate using extended Synchronous Connection Oriented (eSCO) packets and an Orthogonal Frequency Division Multiple Access (OFDMA) radio configured to communicate using Time Division Duplex (TDD), wherein the repeated Bluetooth Tx/Rx pattern is selected based on a TDD frame configuration of the OFDMA radio and an interval of the eSCO packets in the Bluetooth radio; requesting a persistent reservation of at least one sub-frame from the OFDMA radio when the repeated Bluetooth Tx/Rx pattern indicates a Bluetooth packet wherein the Bluetooth radio can not transmit without interference with the OFDMA radio; determining if a transmit time slot and receive time slot exits in each eSCO packet that does not interfere with a transmit subframe and a receive subframe of the OFDMA radio for up to eight consecutive eSCO packets; modifying the repeated Bluetooth Tx/Rx pattern based on the persistent reservation; and communicating using the Bluetooth radio based on the modified repeated Bluetooth Tx/Rx pattern to enable interference free communication for the Bluetooth radio and the OFDMA radio in the multi-radio mobile communication device.
