Abstract

Methods, devices and systems for dynamic scheduling of Wi-Fi or Bluetooth signals based at least in part on LTE schedules are disclosed. In some examples, Wi-Fi or Bluetooth can perform coexistence decisions including Wi-Fi and Bluetooth channel or Adaptive Frequency Hopping (AFH) selection based on modem calculated Rx or Tx indications and device geo location, maximum allowed transmit power per channel for Wi-Fi, and the LTE modem connection state.
