Multi-radio controller and methods for preventing interference between co-located transceivers

摘要

Embodiments of a multi-radio controller and methods for preventing interference between co-located transceivers are generally described herein. In some embodiments, the multi-radio controller operates within a multi-radio device and is configured to cause a wireless local area network (WLAN) transceiver to transmit a triggering frame after an active period of a wireless wide-area network (WWAN) transceiver. The triggering frame indicates the duration of a transmission opportunity, which may be restricted to the time between active periods of the WWAN. In response to receipt of the triggering frame, the WLAN access point is configured to transmit a downlink data frame within the transmission opportunity.

1. An apparatus of a wireless communication device, the apparatus comprising:
wireless local area network (WLAN) interface circuitry to communicate over a WLAN channel; cellular interface circuitry to communicate with cellular network and maintain an LTE connection with the cellular network; and controller circuitry, coupled to the WLAN interface circuitry and cellular interface circuitry, the controller circuitry to: determine a next traffic-free communication period associated with the LTE connection; during the next traffic-free communication period, obtain contention-free access to the WLAN channel in accordance with a transmission opportunity (TXOP) that extends up to an end of the next traffic-free communication period; and configure the WLAN interface circuitry to: generate a reverse direction grant (RDG) frame for transmission over the WLAN channel during the TXOP, the RDG frame including a RUG flag set to indicate that a reverse direction grant is provided; and receive a frame over the WLAN channel during the TXOP, in response to transmission of the RDG frame.
