Neighborhood management between WiFi and unlicensed spectrum radios

1. A method, comprising:

collecting, at a wireless access point (AP) comprising a first WiFi radio, information relating to one or more neighbor devices comprising cellular radios;

setting a schedule of transmissions for the one or more neighbor devices comprising cellular radios based on the collected information;

identifying, at the AP, a neighboring second cellular radio operating using at least a portion of a new radio unlicensed (NR-U) radio spectrum, from among the one or more neighbor devices, wherein the identifying is based on a difference between a time that the AP receives a transmission from the second radio using a frequency within the NR-U radio spectrum and a time in the schedule, comprising:

determining that the difference between the time that the AP receives the transmission from the second radio and the time in the schedule falls within a tolerance; and

synchronizing transmission between the first radio and the second radio by identifying a clock offset between a first clock relating to the first radio and a second clock relating to the second radio, comprising:

identifying the clock offset based on comparing a scheduled time for transmission by the second radio with a measured time relating to receipt of transmission by the second radio.

3. The method of claim 1 , wherein setting the schedule of transmissions comprises:

assigning a respective random identifier for each device in the one or more neighbor devices, wherein each device is configured to transmit at a time based on the random identifier.

4. The method of claim 3 , further comprising:

determining that a difference between the time that the AP receives the transmission from the second radio and the scheduled time does not fall within a tolerance, and in response determining a second transmission schedule for the one or more neighbor devices.

5. The method of claim 4 , wherein determining the second transmission schedule for the one or more neighbor devices comprises:

assigning a respective second random identifier for each device in the one or more neighbor devices, wherein each device is configured to transmit at a time based on the second random identifier.

a memory having instructions stored thereon which, when executed on the processor, performs an operation comprising:

collecting, at a wireless access point (AP) comprising a first WiFi radio, information relating to one or more neighbor devices comprising cellular radios;

setting a schedule of transmissions for the one or more neighbor devices comprising cellular radios based on the collected information;

identifying, at the AP, a neighboring second cellular radio operating using at least a portion of a new radio unlicensed (NR-U) radio spectrum, from among the one or more neighbor devices, wherein the identifying is based on a difference between a time that the AP receives a transmission from the second radio using a frequency within the NR-U radio spectrum and a time in the schedule, comprising:

determining that the difference between the time that the AP receives the transmission from the second radio and the time in the schedule falls within a tolerance; and

synchronizing transmission between the first radio and the second radio by identifying a clock offset between a first clock relating to the first radio and a second clock relating to the second radio, comprising:

identifying the clock offset based on comparing a scheduled time for transmission by the second radio with a measured time relating to receipt of transmission by the second radio.

8. The system of claim 7 , wherein the second radio comprises a 5G radio.

9. The system of claim 7 , wherein identifying, at the AP comprising the first radio, the neighboring second radio comprises:

identifying the second radio as operating using the unlicensed radio spectrum using a fast Fourier transform (FFT) signature relating to the transmission.

10. A non-transitory computer-readable medium having instructions stored thereon which, when executed by a processor, performs an operation comprising:

collecting, at a wireless access point (AP) comprising a first WiFi radio, information relating to one or more neighbor devices comprising cellular radios;

setting a schedule of transmissions for the one or more neighbor devices comprising cellular radios based on the collected information;

identifying, at the AP, a neighboring second cellular radio operating using at least a portion of a new radio unlicensed (NR-U) radio spectrum, from among the one or more neighbor devices, wherein the identifying is based on a difference between a time that the AP receives a transmission from the second radio using a frequency within the NR-U radio spectrum and a time in the schedule, comprising:

determining that the difference between the time that the AP receives the transmission from the second radio and the time in the schedule falls within a tolerance; and

synchronizing transmission between the first radio and the second radio by identifying a clock offset between a first clock relating to the first radio and a second clock relating to the second radio, comprising:

identifying the clock offset based on comparing a scheduled time for transmission by the second radio with a measured time relating to receipt of transmission by the second radio.

11. The computer-readable medium of claim 10 , wherein the second radio comprises a 5G radio.

12. The computer-readable medium of claim 10 , wherein identifying, at the AP comprising the first radio, the neighboring second radio comprises:

identifying the second radio as operating using the unlicensed radio spectrum using a fast Fourier transform (FFT) signature relating to the transmission.

13. The method of claim 1 , further comprising:

collecting, at the AP, information relating to a second one or more neighbor devices comprising cellular radios, based on a second schedule of transmissions;

determining that the information relating to the second one or more neighbor devices is insufficient for identifying neighbors, and in response modifying the second schedule of transmissions; and

identifying, at the AP, a neighboring third cellular radio operating using at least a portion of the NR-U radio spectrum, from among the second one or more neighbor devices, based on the modified second schedule of transmissions.

14. The system of claim 7 , the operation further comprising:

collecting, at the AP, information relating to a second one or more neighbor devices comprising cellular radios, based on a second schedule of transmissions;

determining that the information relating to the second one or more neighbor devices is insufficient for identifying neighbors, and in response modifying the second schedule of transmissions; and

identifying, at the AP, a neighboring third cellular radio operating using at least a portion of the NR-U radio spectrum, from among the second one or more neighbor devices, based on the modified second schedule of transmissions.

collecting, at the AP, information relating to a second one or more neighbor devices comprising cellular radios, based on a second schedule of transmissions;

determining that the information relating to the second one or more neighbor devices is insufficient for identifying neighbors, and in response modifying the second schedule of transmissions; and

identifying, at the AP, a neighboring third cellular radio operating using at least a portion of the NR-U radio spectrum, from among the second one or more neighbor devices, based on the modified second schedule of transmissions.
