Radio coexistence in wireless networks

A radio coexistence system, comprising:

• a coexistence device in a mobile communication device that is operable to communicate with 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 Duplexing (TDD), wherein the coexistence device selects a repeated Bluetooth Transmit/Receive (Tx/Rx) pattern based on a TDD frame configuration of the OFDMA radio and an interval length of the eSCO packets in the Bluetooth radio;
• and
• a persistent reservation device configured to request a persistent reservation of at least one transmit frame from the OFDMA radio when the repeated Bluetooth Tx/Rx pattern indicates a Bluetooth packet wherein the Bluetooth radio can not transmit or receive without interference with the OFDMA radio and determine if a transmit time slot and receive time slot exists 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;
• wherein the coexistence device is configured to modify the repeated Bluetooth Tx/Rx pattern based on the persistent reservation and operate the Bluetooth radio based on the modified repeated Tx/Rx pattern.

A computer program product, comprising a non-transitory computer readable storage medium having a computer readable program code embodied therein, the computer readable program code adapted to be executed to implement a method for reducing interference in collocated radios, comprising:

• identifying a repeating transmit/receive (Tx/Rx) pattern for multiple radios located in a mobile communication device having a Bluetooth radio collocated with an Orthogonal Frequency Division Multiple Access (OFDMA) radio configured to communicate using Time Division Duplex (TDD);
• requesting a persistent reservation of at least one sub-frame from the OFDMA radio when the repeating 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 extended Synchronous Connection Oriented (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 repeating Tx/Rx pattern based on the persistent reservation;
• and
• communicating using the Bluetooth radio based on the modified repeating Tx/Rx pattern to enable interference free communication for the Bluetooth radio and the OFDMA radio in the multi-radio mobile communication device.
