RF COLLABORATION METHOD TO REDUCE RF INTERFERENCE WITH WIRELESS ADAPTER

摘要

A system and method for preventing a wireless controller system and WiFi radio system within a game console from interfering with each other. Specifically, the WiFi system is adapted to avoid activating its transmitter during the controller receive times by detecting a signal sent to the WiFi module indicating where the controller receive times occur without an explicit signal indicative of the controller receive times.

主权项

1. An apparatus, comprising:
a memory; a microprocessor; a first radio subsystem that transmits data to and receives data from a network infrastructure; and a second radio subsystem that transmits data to and receives data from a wireless accessory during defined time slots that repeat over time, the first and second radio subsystems operating independently of each other; and a radio frequency (RF) energy detection module that detects wireless transmissions of said second radio subsystem and autonomously generates, based on the detected wireless transmissions of said second radio subsystem, a frame timing signal that reflects the time slots in which data is transmitted and received by the second radio subsystem, the frame timing signal generated by the RF energy detection module being used to control the timing of transmissions by said first radio subsystem to reduce interference between the first and second radio subsystems.
