Reducing interference in collocated radios

摘要

Technology for reducing interference in collocated radios is disclosed. One method comprises logging transmit/receive information from a Bluetooth radio and an OFDMA radio for a repeating Tx/Rx pattern. Data collisions between the radios are identified. A persistent reservation is requested in the OFDMA radio for collisions in the repeating Tx/Rx pattern. A repeating Bluetooth Tx/Rx pattern is derived from the logged data and the collision data. Bluetooth radio communication is accomplished using the Bluetooth Tx/Rx pattern.

1. A method for reducing interference in collocated radios of a multi-radio mobile communication device, comprising:
logging transmit/receive (Tx/Rx) information for a Bluetooth radio and an Orthogonal Frequency Division Multiple Access (OFDMA) radio for a time equivalent to T consecutive Bluetooth intervals, where T is a repeating Tx/Rx pattern length; identifying if at least one of a Bluetooth packet collision and an OFDMA data collision occur from the logged data for the T Bluetooth intervals; requesting a persistent reservation of at least one OFDMA radio subframe, wherein the OFDMA radio will not schedule data to allow a Bluetooth packet to be transmitted during an interval where the Bluetooth packet collision or the OFDMA data collision can occur; determining a repeating Bluetooth Tx/Rx pattern of length T, wherein the pattern comprises a transmit slot number for each Bluetooth packet and a persistent reservation transmit slot number for each Bluetooth packet collision or OFDMA data collision; and communicating using the Bluetooth radio based on the repeating Bluetooth Tx/Rx pattern to enable reduced interference between the Bluetooth radio and the OFDMA radio in a multi-radio mobile communication device.
