Abstract

Claims (26)

1 . A method, comprising:

detecting, by a first device, a ultra-wideband (UWB) signal, comprising a physical layer protocol data unit (PPDU), received from a second device via a UWB antenna of the first device, the PPDU including a communication parameter;

communicating, from a physical layer of the first device through a medium access control (MAC) layer to an application of the first device, measurement data corresponding to the UWB signal;

generating, by the first device, a measurement report corresponding to the UWB signal;

determining, by the first device, based on the communication parameter, a transmission mode for the measurement report; and

transmitting, by the first device, based on the determined transmission mode, the measurement report to the second device via a non-UWB communication device of the first device.

2 . The method of claim 1 , further comprising configuring, by the first device with the second device, to use a non-UWB communication link for sending measurement reports corresponding to UWB signals between the first device and the second device.

3 . The method of claim 1 , wherein the measurement data is communicated from the physical layer via an interface to the application.

4 . The method of claim 3 , wherein the interface is a first interface, the method further comprising:

communicating the measurement report via a second interface to the non-UWB communication device for transmission to the second device.

5 . The method of claim 3 , wherein the interface comprises a medium access control (MAC) layer management entity (MLME) between a MAC layer and the application.

6 . The method of claim 1 , wherein the non-UWB communication device transmits the measurement report via a protocol comprising at least one of a wireless local area network (WLAN) protocol, cellular protocol, Bluetooth wireless protocol, or non-wireless protocol.

7 . A first device comprising:

an ultra-wideband (UWB) antenna;

a non-UWB communication device; and

one or more processors configured to:

detect a UWB signal, comprising a physical layer protocol data unit (PPDU), received from a second device via the UWB antenna, the PPDU including a communication parameter;

communicate, from a physical layer of the first device through a medium access control (MAC) layer to an application of the first device, measurement data corresponding to the UWB signal;

generate a measurement report corresponding to the UWB signal;

determine, based on the communication parameter, a transmission mode for the measurement report; and

transmit the measurement report to the second device via the non-UWB communication device based on the determined transmission mode.

8 . The first device of claim 7 , wherein the measurement data is communicated from the physical layer via an interface to the application.

9 . The first device of claim 8 , wherein the interface is a first interface, and wherein the application is configured to communicate the measurement report via a second interface to the non-UWB communication device for transmission to the second device.

10 . The first device of claim 7 , wherein the non-UWB communication device transmits the measurement report via a protocol comprising at least one of a wireless local area network (WLAN) protocol, cellular protocol, Bluetooth wireless protocol, or non-wireless protocol.

11 . The first device of claim 7 , wherein the one or more processors are configured to:

use a non-UWB communication link for sending measurement reports corresponding to UWB signals between the first device and the second device.
