Abstract

Systems and methods for synchronizing communications between a User Equipment (UE) and Base Station (BS) using a synchronization signal structure. The synchronization signal structure can include a sequence of Synchronization Signals (SS) including repetitions of a synchronization signal burst set. The synchronization signal burst set can include a plurality of synchronization signal bursts. The synchronization signal bursts can include a plurality of synchronization signal blocks, wherein the synchronization signal blocks can include a plurality of Synchronization Signals (SS).

Claims (22)

1. A method for a base station, the method comprising:

encoding, at the base station, a synchronization signal burst set comprising a plurality of bursts of synchronization signal blocks (SSBs) in series, wherein the plurality of bursts of SSBs includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), and wherein the SSS is not repeated with the synchronization signal burst set that is within a synchronization signal burst set duration; and

beam sweeping based on the plurality of bursts of SSBs within the synchronization signal burst set.

2. The method of claim 1 , wherein the synchronization signal burst set is within the synchronization signal burst set duration comprising a predetermined value for the base station and one or more user equipment.

3. The method of claim 2 , further comprising using a same beam in one or more instance of the plurality of bursts of SSBs within the synchronization signal burst set that is within the synchronization signal burst set duration.

4. The method of claim 1 , wherein the beam sweeping comprises using a number of beams for the SSS that are different in different instances of the plurality of bursts of SSBs within the synchronization signal burst set.

5. The method of claim 4 , further comprising repeating a group of the plurality of bursts of SSBs across a plurality of the synchronization signal burst set.

6. The method of claim 1 , wherein the plurality of bursts of SSBs has a predetermined periodicity.

7. The method of claim 1 , wherein each of the plurality of bursts of SSBs includes a same number of SSBs such that a predetermined periodicity between two of the plurality of bursts of SSBs is a fixed interval.

8. The method of claim 1 , wherein a relative transmission timing of the plurality of bursts of SSBs is the same between two of the plurality of bursts of SSBs.

9. The method of claim 1 , wherein an interval between a starting time of consecutive ones of the plurality of bursts of SSBs is fixed.

10. A base station, comprising:

one or more processors to encode, at the base station, a synchronization signal burst set comprising a plurality of bursts of synchronization signal blocks (SSBs) in series, wherein the plurality of bursts of SSBs includes a primary synchronization signal (PSS) and a secondary synchronization signal (SSS), and wherein the SSS is not repeated with the synchronization signal burst set that is within a synchronization signal burst set duration; and

a transceiver to beam sweep based on the plurality of bursts of SSBs within the synchronization signal burst set.

11. The base station of claim 10 , wherein the synchronization signal burst set is within the synchronization signal burst set duration comprising a predetermined value for the base station and one or more user equipment.

12. The base station of claim 11 , wherein the transceiver is further to transmit a same beam in one or more instance of the plurality of bursts of SSBs within the synchronization signal burst set that is within the synchronization signal burst set duration.

13. The base station of claim 10 , wherein the transceiver performs the beam sweep by transmitting a number of beams for the SSS that are different in different instances of the plurality of bursts of SSBs within the synchronization signal burst set.

14. The base station of claim 13 , wherein the one or more processors are further configured to repeat a group of the plurality of bursts of SSBs across a plurality of the synchronization signal burst set.

15. The base station of claim 10 , wherein the plurality of bursts of SSBs has a predetermined periodicity.

16. The base station of claim 10 , wherein each of the plurality of bursts of SSBs includes a same number of SSBs such that a predetermined periodicity between two of the plurality of bursts of SSBs is a fixed interval.

17. The base station of claim 10 , wherein a relative transmission timing of the plurality of bursts of SSBs is the same between two of the plurality of bursts of SSBs.

18. The base station of claim 10 , wherein an interval between a starting time of consecutive ones of the plurality of bursts of SSBs is fixed.
