Abstract

Various aspects described herein relate to techniques of spectrum sharing in beacon-assisted multi-tier wireless communications systems (e.g., 5G New Radio). A method of spectrum sharing in multi-tier wireless communications is provided that may include generating, at a first apparatus, a beacon signal including information of spectrum usage, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters, and sending the beacon signal to at least a second apparatus, wherein the first apparatus and the second apparatus are in a same tier or different tiers.

Claims

1. A method of spectrum sharing in multi-tier wireless communications, comprising:

generating, at a first apparatus, a beacon signal including information of spectrum usage, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters; and

sending, by the first apparatus, the beacon signal to at least a second apparatus, wherein the first apparatus and the second apparatus are in a same tier or different tiers.

2. The method of claim 1, wherein the beacon signal includes an identification of the first apparatus.

3. The method of claim 1, further comprising:

enabling inter-tier or intra-tier coordination for spectrum sharing based on the beacon signal.

4. The method of claim 1, further comprising:

enabling timing synchronization for spectrum sharing based on the beacon signal.

5. The method of claim 1, further comprising:

sending the beacon signal with controlled power in one or more resource blocks.

6. The method of claim 1, further comprising:

sending the beacon signal periodically.

7. The method of claim 1, wherein the first apparatus is in a tier having a higher priority for resources allocation than the tier of the second apparatus.

8. The method of claim 1, wherein the first apparatus and the second apparatus share spectrum in time or frequency.

9. An apparatus for spectrum sharing in multi-tier wireless communications, comprising:

a memory configured to store instructions;

at least one processor coupled to the memory, wherein the at least one processor is configured to execute the instructions to generate a beacon signal including information of spectrum usage, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters; and

a transceiver configured to transmit the beacon signal to at least another apparatus, wherein the two apparatuses are in a same tier or different tiers.

10. The apparatus of claim 9, wherein the beacon signal includes an identification of the apparatus.

11. The apparatus of claim 9, wherein the at least one processor is further configured to execute the instructions to enable inter-tier or intra-tier coordination for spectrum sharing based on the beacon signal.

12. The apparatus of claim 9, wherein the at least one processor is further configured to execute the instructions to enable timing synchronization for spectrum sharing based on the beacon signal.

13. The apparatus of claim 9, wherein the transceiver is further configured to transmit the beacon signal with controlled power in one or more resource blocks.

14. The apparatus of claim 9, wherein the transceiver is further configured to transmit the beacon signal periodically.

15. The apparatus of claim 9, wherein the apparatus is in a tier having a higher priority for resources allocation than the tier of the at least another apparatus.

16. A computer-readable medium storing computer code executable by a processor for multi-tier wireless communications, comprising:

code for generating, at a first apparatus, a beacon signal including information of spectrum usage, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters; and

code for sending, by the first apparatus, the beacon signal to at least a second apparatus, wherein the first apparatus and the second apparatus are in a same tier or different tiers.

17. The computer-readable medium of claim 16, wherein the beacon signal includes an identification of the first apparatus.

18. The computer-readable medium of claim 16, further comprising:

code for enabling inter-tier or intra-tier coordination for spectrum sharing based on the beacon signal.

19. The computer-readable medium of claim 16, further comprising:

code for enabling timing synchronization for spectrum sharing based on the beacon signal.

20. The computer-readable medium of claim 16, further comprising:

code for sending the beacon signal with controlled power in one or more resource blocks.

21. The computer-readable medium of claim 16, further comprising:

code for sending the beacon signal periodically.

22. The computer-readable medium of claim 16, wherein the first apparatus is in a tier having a higher priority for resources allocation than the tier of the second apparatus.

23. A method of spectrum sharing in multi-tier wireless communications, comprising:

determining, at a first apparatus, whether a beacon signal including information of spectrum usage is received from a second apparatus, wherein the information includes at least one or more of a pilot reference, resources allocation, one or more usage entities, or one or more sharing parameters; and

utilizing, at the first apparatus and in response to the beacon signal being received from the second apparatus, spectrum based on the information received in the beacon signal.

24. The method of claim 23, further comprising:

determining, at the first apparatus, whether the beacon signal including an identification of the second apparatus.

25. The method of claim 23, further comprising:

operating, at the first apparatus and in response to the beacon signal not being received from the second apparatus, in a listen-before-talk (LBT) mode.

26. The method of claim 23, further comprising:

enabling inter-tier or intra-tier coordination for spectrum sharing with at least the second apparatus based on the beacon signal.

27. The method of claim 23, further comprising:

enabling timing synchronization for spectrum sharing with at least the second apparatus based on the beacon signal.

28. The method of claim 23, further comprising:

receiving the beacon signal with controlled power in one or more resource blocks.

29. The method of claim 23, further comprising:

receiving the beacon signal periodically.

30. The method of claim 23, wherein the first apparatus is in a tier having a same or lower priority for resources allocation than the tier of the second apparatus.
