Abstract
The disclosure provides a network access method and a user equipment (UE) using the same method in an environment of a 5G communication system. In an exemplary embodiment in accordance with the disclosure, the disclosure is directed to a network access method for a UE. The method would include not limited to: receiving a Synchronization Signal/physical broadcast channel Block (SSB) which comprises at least one of a physical broadcast channel (PBCH), a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or mapping information; and determining from the SSB at least one of a SSB candidate number, a SSB index or a SSB pattern.

Claim
1. A network access method used by a user equipment (UE), the method comprising:
receiving, within a Synchronization Signal/physical broadcast channel Block (SSB) transmission period which contains multiple transmission opportunities of SSBs having a same index, a received SSB, and once the received SSB has been received within the SSB transmission period, no other SSB having the same SSB index as the received SSB is received within the SSB transmission period, and the received SSB comprises a physical broadcast channel (PBCH), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS); and
determining directly from the received SSB, a SSB candidate number and a SSB index.
2. The network access method of claim 1, wherein a next generation Node B (gNB) configures the SSB transmission period.
3. The network access method of claim 1, wherein the SSB transmission period comprises a plurality of windows.
4. The network access method of claim 3, wherein each window of the plurality of windows comprises a plurality of slots, wherein a slot of the plurality of slots has only two SSB transmission opportunities.
5. The network access method of claim 3, wherein the first window of the plurality of windows is located at the start of the SSB transmission period.
6. The network access method of claim 3, wherein the windows of the plurality of windows are adjacent to each other and do not overlap.
7. The network access method of claim 3, wherein the SSB transmission period is not smaller than the total time occupied by the plurality of windows.
8. The network access method of claim 3, wherein a first window comprises a plurality of SSB transmission opportunities, each of the SSB transmission opportunities is located in a position in the first window, each of the SSB transmission opportunities has a spatial relation,
wherein a second window comprises another plurality of SSB transmission opportunities, each of the SSB transmission opportunities of the second window is located in a position in the second window, each of the SSB transmission opportunities of the second window has a spatial relation,
wherein if a SSB transmission opportunity of the first window and a SSB transmission opportunity of the second window are located in the same position, the SSB transmission opportunity of the first window and the SSB transmission opportunity of the second window have the same spatial relation.
9. The network access method of claim 8, wherein the first window and the second window are in the same SSB transmission period.
10. The network access method of claim 8, wherein the first window and the second window are in different SSB transmission periods.
11. The network access method of claim 8, wherein a SSB transmission opportunity of the first window and a SSB transmission opportunity of the second window are separated by a predetermined time gap.
12. The network access method of claim 8, wherein an average number of SSB transmission opportunities of the same spatial relation in a SSB transmission period is determined at least by one of a total number of SSB transmission opportunities in the SSB transmission period, a number of spatial relations for SSB or a number of SSB indexes.
13. A user equipment (UE) comprising:
a wireless receiver; and
a processor coupled to the wireless receiver and configured to:
receive, via the wireless receiver and within a Synchronization Signal/physical broadcast channel Block (SSB) transmission period which contains multiple transmission opportunities of SSBs having a same index, a received SSB, and once the received SSB has been received within the SSB transmission period, no other SSB having the same SSB index as the received SSB is received within the SSB transmission period, and the received SSB comprises a physical broadcast channel (PBCH), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS); and
determine directly from the received SSB, a SSB candidate number and a SSB index.
14. The UE of claim 13, wherein the SSB transmission period comprises a plurality of windows.
15. The UE of claim 14, wherein a next generation Node B (gNB) configures the SSB transmission period.
16. The UE of claim 14, wherein each window of the plurality of windows comprises a plurality of slots, wherein a slot of the plurality of slots has only two SSB transmission opportunities.
17. The UE of claim 14, wherein the first window of the plurality of windows is located at the start of the SSB transmission period.
18. The UE of claim 14, wherein the windows of the plurality of windows are adjacent to each other and do not overlap.
19. The UE of claim 14, wherein the SSB transmission period is not smaller than the total time occupied by the plurality of windows.
20. The UE of claim 14, wherein a first window comprises a plurality of SSB transmission opportunities, each of the SSB transmission opportunities is located in a position in the first window, each of the SSB transmission opportunities has a spatial relation,
wherein a second window comprises another plurality of SSB transmission opportunities, each of the SSB transmission opportunities of the second window is located in a position in the second window, each of the SSB transmission opportunities of the second window has a spatial relation,
wherein if a SSB transmission opportunity of the first window and a SSB transmission opportunity of the second window are located in the same position, the SSB transmission opportunity of the first window and the SSB transmission opportunity of the second window have the same spatial relation.
21. The UE of claim 20, wherein the first window and the second window are in the same SSB transmission period.
22. The UE of claim 20, wherein the first window and the second window are in different SSB transmission periods.
23. The UE of claim 20, wherein a SSB transmission opportunity of the first window and a SSB transmission opportunity of the second window are separated by a predetermined time gap.
24. The UE of claim 20, wherein an average number of SSB transmission opportunities of the same spatial relation in a SSB transmission period is determined at least by one of a total number of SSB transmission opportunities in the SSB transmission period, a number of spatial relations for SSB or a number of SSB indexes.
