Abstract

A method for synchronization in a wireless system. In the method, a physical broadcast channel (PBCH) includes one or more bits, wherein the one or more bits indicate additional system information when a frequency of the wireless system is within a frequency range up to a predefined frequency and indicate a location of a slot group in a synchronization signal burst set when the frequency of the wireless system is above the predefined frequency, and wherein the slot group comprises at least one synchronization signal block and the synchronization signal burst set includes the slot group.

Claims (32)

1. A method in a base station for synchronization in a wireless system comprising:

transmitting a Synchronization Signal Block (SSB) comprising a physical broadcast channel (PBCH) including one or more bits, wherein the SSB is one of a set of candidate SSBs within a half frame and a total number of the candidate SSBs within the half frame is an integer greater than zero and wherein the PBCH is interleaved with a downlink pilot signal sequence;

wherein when a frequency of the wireless system is within a frequency range up to a predefined frequency, the one or more bits indicate additional system information and when the frequency of the wireless system is above the predefined frequency, the one or more bits indicate a location of a slot group containing the SSB among the set of candidate SSBs within the half frame.

2. The method according to claim 1 , wherein the additional system information comprises a frame number offset of a coexisting system relative to the wireless system.

3. The method according to claim 1 , wherein the additional system information comprises system information of a neighbor cell in a coexisting system.

4. The method according to claim 3 , wherein the system information of a neighbor cell in the coexisting system comprises an identifier of the neighbor cell.

5. The method according to claim 1 , wherein the additional system information comprises configuration information of a synchronization signal burst set of a neighbor cell in the wireless system, and an indication related to synchronization information in the wireless system.

6. The method according to claim 5 , wherein the configuration information of the synchronization signal burst set of the neighbor cell in the wireless system comprises a number of the SSBs actually transmitted in the neighbor cell and periodicity of the synchronization signal burst set.

7. The method according to claim 1 , wherein the downlink pilot signal sequence carries information indicating a location of the SSB within the slot group.

8. A base station in a wireless system comprising:

a processor; and

a memory containing instructions which, when executed by the processor, cause the base station to:

transmit a Synchronization Signal Block (SSB) comprising a physical broadcast channel (PBCH) including one or more bits, wherein the SSB is one of a set of candidate SSBs within a half frame and a total number of the candidate SSBs within the half frame is an integer greater than zero and wherein the PBCH is interleaved with a downlink pilot signal sequence;

wherein when a frequency of the wireless system is within a frequency range up to a predefined frequency, the one or more bits indicate additional system information and when the frequency of the wireless system is above the predefined frequency, the one or more bits indicate a location of a slot group containing the SSB among the set of candidate SSBs within the half frame.

9. The base station according to claim 8 , wherein the downlink pilot signal sequence carries information indicating a location of the SSB within the slot group.

10. A method in a terminal device for synchronization in a wireless system comprising:

receiving a Synchronization Signal Block (SSB) comprising a physical broadcast channel (PBCH) including one or more bits from a base station, wherein the SSB is one of a set of candidate SSBs within a half frame and a total number of the candidate SSBs within the half frame is an integer greater than zero and wherein the PBCH is interleaved with a downlink pilot signal sequence;

wherein when a frequency of the wireless system is within a frequency range up to a predefined frequency, the one or more bits indicate additional system information and when the frequency of the wireless system is above the predefined frequency, the one or more bits indicate a location of a slot group containing the SSB among the set of candidate SSB s within the half frame.

11. The method according to claim 10 , wherein the additional system information comprises a frame number offset of a coexisting system relative to the wireless system.

12. The method according to claim 10 , wherein the additional system information comprises system information of a neighbor cell in a coexisting system.

13. The method according to claim 12 , wherein the system information of a neighbor cell in the coexisting system comprises an identifier of the neighbor cell.

14. The method according to claim 10 , wherein the additional system information comprises configuration information of a synchronization signal burst set of a neighbor cell in the wireless system.

15. The method according to claim 14 , wherein the configuration information of the synchronization signal burst set of a neighbor cell in the wireless system comprises a number of the SSB s actually transmitted in the neighbor cell and periodicity of the synchronization signal burst set.

16. The method according to claim 10 , wherein the additional system information comprises an indication related to synchronization information in the wireless system.

17. The method according to claim 10 , wherein the one or more bits are included in a payload of the PBCH and wherein the one or more bits are most significant bits of the payload.

18. The method according to claim 10 , wherein the downlink pilot signal sequence carries information indicating a location of the SSB within the slot group.

19. A terminal device in a wireless system comprising:

a processor; and

a memory containing instructions which, when executed by the processor, cause the terminal device to:

receive a Synchronization Signal Block (SSB) comprising a physical broadcast channel (PBCH) including one or more bits from a base station, wherein the SSB is one of a set of candidate SSBs within a half frame and a total number of the candidate SSBs within the half frame is an integer greater than zero and wherein the PBCH is interleaved with a downlink pilot signal sequence;

wherein when a frequency of the wireless system is within a frequency range up to a predefined frequency, the one or more bits indicate additional system information and when the frequency of the wireless system is above the predefined frequency, the one or more bits indicate a location of a slot group containing the SSB among the set of candidate SSBs within the half frame.

20. The terminal device according to claim 19 , wherein the downlink pilot signal sequence carries information indicating a location of the SSB within the slot group.
