Abstract

Systems, apparatuses, and methods for implementing a dual-purpose millimeter-wave frequency band transmitter are disclosed. A system includes a dual-purpose transmitter sending a video stream over a wireless link to a receiver. In some embodiments, the video stream is generated as part of an augmented reality (AR) or virtual reality (VR) application. The transmitter operates in a first mode to scan and map an environment of the transmitter and receiver. The transmitter generates radio frequency (RF) signals in a first frequency range while operating in the first mode. Additionally, the transmitter operates in a second mode to send video data to the receiver, and the transmitter generates RF signals in the first frequency range while operating in the second mode.

Claims (65)

1. A system comprising:

a transmitter configured to:

operate in a first mode in which the transmitter generates radio frequency (RF) signals in a scanning pattern to map an environment of the transmitter; and

perform a beamforming training procedure, wherein to perform the beamforming procedure, the transmitter is configured to:

utilize the map of the environment to identify one or more obstacles in the environment; and

skip one or more sectors during the beamforming training procedure, responsive to the one or more sectors being identified as corresponding to obstacles by the map.

2. The system as recited in claim 1 , wherein the transmitter is configured to:

receive reflections of the RF signals;

generate reflection data based on the reflected RF signals; and

process the reflection data to generate the map of the environment.

3. The system as recited in claim 1 , wherein the transmitter is further configured to:

determine an optimal antenna sector from the map of the environment; and

send video data to the receiver via the optimal antenna sector.

4. The system as recited in claim 1 , wherein the transmitter is configured to operate in a second mode to transmit video data, and an obstacle represents an object in the environment that would interfere with communication between the transmitter and a receiver.

5. The system as recited in claim 1 , wherein the system is further configured to:

render at least a portion of a first video frame based on the map of the environment; and

send the first video frame to the receiver.

6. The system as recited in claim 5 , wherein the system is further configured to:

detect one or more objects in the map of the environment; and

render the one or more objects in the first video frame.

7. The system as recited in claim 1 , wherein the transmitter is configured to transmit radio frequency (RF) signals in a first frequency range corresponding to frequencies with wavelengths between 1 and 10 millimeters.

8. A method comprising:

operating, by a transmitter, in a first mode to generate radio frequency (RF) signals in a scanning pattern to map an environment of the transmitter;

performing, by the transmitter, a beamforming training procedure, wherein performing the beamforming procedure comprises:

utilizing the map of the environment to identify one or more obstacles in the environment; and

skipping one or more sectors during the beamforming training procedure, responsive to the one or more sectors being identified as corresponding to obstacles by the map.

9. The method as recited in claim 8 , further comprising:

receiving reflections of the RF signals;

generating reflection data based on the reflected RF signals; and

processing the reflection data to generate a map of the environment.

10. The method as recited in claim 8 , wherein an obstacle represents an object in the environment that would interfere with communication between the transmitter and a receiver, and the method further comprises:

operating, by the transmitter, in a second mode to transmit video data.

11. The method as recited in claim 10 , further comprising:

determining an optimal beam from the map of the environment; and

sending video data to the receiver via the optimal beam.

12. The method as recited in claim 8 , further comprising:

rendering at least a portion of a first video frame based on the map of the environment; and

sending the first video frame to the receiver.

13. The method as recited in claim 12 , further comprising:

detecting one or more objects in the map of the environment; and

rendering the one or more objects in the first video frame.

14. The method as recited in claim 8 , further comprising transmitting radio frequency (RF) signals in a first frequency range corresponding to frequencies with wavelengths between 1 and 10 millimeters.

15. An apparatus comprising:

a processor;

a memory; and

a radio frequency (RF) transceiver module;

wherein the apparatus is configured to:

operate in a first mode in which the transmitter generates radio frequency (RF) signals in a scanning pattern to map an environment of the transmitter; and

perform a beamforming training procedure, wherein to perform the beamforming procedure, the transmitter is configured to:

utilize the map of the environment to identify one or more obstacles in the environment; and

skip one or more sectors during the beamforming training procedure, responsive to the one or more sectors being identified as corresponding to obstacles by the map.

16. The apparatus as recited in claim 15 , wherein the apparatus is configured to:

receive reflections of the RF signals;

generate reflection data based on the reflected RF signals; and

process the reflection data to generate the map of the environment.

17. The apparatus as recited in claim 15 , wherein the apparatus is configured to operate in a second mode to transmit video data, and an obstacle represents an object in the environment that would interfere with communication between the transmitter and a receiver.

18. The apparatus as recited in claim 17 , wherein the apparatus is further configured to:

determine an optimal beam from the map of the environment; and

send video data to the receiver via the optimal beam.

19. The apparatus as recited in claim 15 , wherein the apparatus is configured to:

render at least a portion of a first video frame based on the map of the environment; and

send the first video frame to the receiver.

20. The apparatus as recited in claim 19 , wherein the apparatus is further configured to:

detect one or more objects in the map of the environment; and

render the one or more objects in the first video frame.
