Abstract
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.
Claims22
User Equipment (UE) comprising:
- a multi-radio controller for controlling a Wi-Fi transceiver and a LTE transceiver, the multi-radio controller configured to:
- determine a duration of a transmission opportunity (TXOP) based on an active period interval of the LTE transceiver;
- configure a triggering frame to indicate that the Wi-Fi transceiver is granting permission to an access point to send data in accordance with a reverse direction (RD) protocol, the triggering frame to indicate at least a duration of the TXOP;
- and
- transmit the triggering frame within the TXOP immediately after an active period of the LTE transceiver,
- wherein the duration of he TXOP is determined prior to configuration and transmission of the triggering frame.
A method performed by user equipment (UE) for controlling a Wi-Fi transceiver and a LTE transceiver, the method comprising:
- determining a duration of a transmission opportunity (TXOP) based on an active period interval of the LTE transceiver;
- configuring a triggering frame to indicate that the Wi-Fi transceiver is granting permission to an access point to send data in accordance with a reverse direction (RD) protocol, the triggering frame to indicate at least a duration of the TXOP;
- and
- transmitting the triggering frame within the TXOP immediately after an active period of the LTE transceiver,
- wherein the duration of the TXOP is determined prior to configuration and transmission of the triggering frame.
A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for controlling a multi-radio controller of user equipment (UE) having a Wi-Fi transceiver and a LTE transceiver, the operations to configure the UE to:
- determine a duration of a transmission opportunity (TXOP) based on an active period interval of the LTE transceiver;
- configure a triggering frame to indicate that the Wi-Fi transceiver is granting permission to an access point to send data in accordance with a reverse direction (RD) protocol, the triggering frame to indicate at least a duration of the TXOP;
- and
- transmit the triggering frame within the TXOP immediately after an active period of the LTE transceiver,
- wherein the duration of the TXOP is determined prior to configuration and transmission of the triggering frame.
