Abstract

A system for 5G radio access networks, that enables smart RF signal repeater devices to perform many of the functions of a 5G base station to extend millimeter wave coverage for 5G communication networks while reducing costs, increasing versatility and optimizing coverage for user devices (UEs). The devices may include outdoor network repeaters and indoor subscriber repeaters, and other mmWave network transmitter devices in a mmWave network. Different types of 5G wireless communication networks may be employed including Open Radio Access Network (O-RAN), and Next Gen Radio Access Network (NG-RAN).

First claim

The invention claimed is:

1. A method of operating a wireless repeater, comprising:
receiving, from a cloud-based management engine, a set of beam patterns targeting a service area for the wireless repeater based on a fixed installation of the wireless repeater;
receiving, from a wireless base station, a first sequence of synchronization signals;
repeatedly adjusting a beamforming antenna to transmit a second sequence of synchronization signals with a corresponding sequence of the set of beam patterns within the service area of the wireless repeater;
receiving, from the wireless base station, a time schedule for communication between the wireless base station and a plurality of user equipment devices within the service area;
receiving, from the plurality of user equipment devices and according to the time schedule, uplink electromagnetic signals to be delivered to the wireless base station;
transmitting the uplink electromagnetic signals to the wireless base station;
receiving, from the plurality of user equipment devices, a corresponding plurality of uplink grant requests; and
transmitting the plurality of uplink grant requests to the wireless base station.

2. The method of claim 1 , wherein the second sequence is equal to the first sequence.

3. The method of claim 1 , wherein the first sequence of synchronization signals includes a synchronization signal block sweep for wireless communication.

4. The method of claim 1 , further comprising:
demodulating the first sequence of synchronization signals; and
remodulating the demodulated first sequence of synchronization signals to provide the second sequence of synchronization signals.

5. The method of claim 1 , further comprising:
receiving, from the wireless base station via an out-of-band channel, a schedule for the first sequence of synchronization signals.

6. The method of claim 1 , wherein the wireless base station is a gNodeB for 5G wireless communications.

7. The method of claim 1 , wherein the wireless base station is a wireless base station for millimeter wave (mmW) communications.

8. The method of claim 1 , wherein the beamforming antenna is a holographic beamforming antenna.

9. The method of claim 1 , wherein the sequence of beam patterns is a raster sequence of narrow beam patterns that collectively fill the service area.

10. The method of claim 9 , wherein the narrow beam patterns are vertical fan beam patterns having a narrow horizontal beam width and a wide vertical beam width.

11. The method of claim 9 , wherein the narrow beam patterns are horizontal fan beam patterns having a wide horizontal beam width and a narrow vertical beam width.

12. The method of claim 1 , wherein the sequence of beam patterns is a pseudorandom or compressive imaging sequence of beam patterns that collectively fill the service area.

13. The method of claim 1 , wherein the service area of the wireless repeater includes an area outside of a service area of the wireless base station.

14. The method of claim 13 , wherein the service area of the wireless base station is a service area limited by line of sight, foliage loss, distance, or fade.

15. The method of claim 13 , wherein the sequence of beam patterns collectively fills the area outside of the service area of the wireless base station.

16. The method of claim 1 , wherein the set of beam patterns is customized based on an environment of the targeted service area.

17. A wireless repeater, comprising:
a beamforming antenna; and
one or more processors coupled to one or more memories having instructions stored thereon to cause the wireless repeater to carry out a method that includes:

receiving, from a wireless base station, a first sequence of synchronization signals;
repeatedly adjusting a beamforming antenna to transmit a second sequence of synchronization signals with a corresponding sequence of the set of beam patterns within the service area of the wireless repeater;
receiving, from the wireless base station, a time schedule for communication between the wireless base station and a plurality of user equipment devices within the service area;
receiving, from the plurality of user equipment devices and according to the time schedule, uplink electromagnetic signals to be delivered to the wireless base station;
transmitting the uplink electromagnetic signals to the wireless base station;
receiving, from the plurality of user equipment devices, a corresponding plurality of uplink grant requests; and

transmitting the plurality of uplink grant requests to the wireless base station.

18. The wireless repeater of claim 17 , wherein the wireless base station is a wireless base station for millimeter wave (mmW) communications.

19. The wireless repeater of claim 17 , wherein the first sequence of synchronization signals includes a synchronization signal block sweep for wireless communication.
