Abstract: The invention provides a mobile communication device having a first wireless communication module with a strong driving circuit, and a second wireless communication module with a weak driving circuit. The first wireless communication module is coupled to the second wireless communication module via only one wire. The first wireless communication module sends a first traffic pattern of a first wireless transceiving to the second wireless communication module via the wire, and receives a second traffic of a second wireless transceiving from the second wireless communication module via the wire. The second traffic pattern indicates whether the second wireless communication module decides to use a remaining period of time, in which the first wireless communication module is not required to perform wireless transceiving, for the second wireless transceiving.

Abstract: Methods for preventing coexistence interference between a Bluetooth Low Energy (BLE) radio and a collocated LTE radio are provided. In a first solution, the BLE radio adds padding bytes to BLE packets such that the total packet length falls in a specific range to prevent coexistence interference. In a second solution, the BLE radio limits the total BLE packet length to a predefined length to prevent coexistence interference. In a third solution, the data rate for transmitting the BLE packets is higher than a predefined rate to prevent coexistence interference. In a fourth solution, the BLE radio dynamically adjusts the time inter-frame-spacing (T_IFS) value to prevent coexistence interference with the collocated LTE radio.

Abstract: A wireless device having a central control entity that coordinates multiple radio transceivers co-located within the same device platform to mitigate coexistence interference. The wireless device comprises an LTE transceiver, a WiFi transceiver, a BT transceiver, or a GNSS receiver. In one embodiment, the central control entity receives radio signal information from the transceivers and determines control information. The control information is used to trigger FDM solution such that the transceivers operate in designated frequency channels to mitigate co-existence interference. In another embodiment, the central control entity receives traffic and scheduling information from the transceivers and determines control information. The control information is used to trigger TDM solution such that the transceivers are scheduled for transmitting or receiving radio signals over specific time duration to mitigate co-existence interference. In yet another embodiment, power control solution is used to mitigate coexistence interference.
