Abstract

Methods and systems are provided to allow signals for multiple service slices using sub-bands that are part of a system bandwidth. In some cases the signals for a given service slice are self-contained within the sub-band in the sense that channels for initial access and ongoing communications are all located within the sub-band. A receiver that is only accessing the given service slice need only be capable of receiving the sub-band. The method may involve, in a first sub-band predefined for a first service slice, transmitting first initial access information for a first service associated with the first service slice. The method further involves, in a second sub-band predefined for a second service slice, transmitting second initial access information for a second service associated with the second service slice. The second sub-band is different from the first sub-band.

First claim

We claim:

1. A method performed by a transmitter, the method comprising:
only in a first sub-band predefined for a first service, the first sub-band within a carrier bandwidth, the transmitter transmitting first initial access information for the first service, the first initial access information including a first synchronization channel; and
only in a second sub-band predefined for a second service, the second sub-band within the carrier bandwidth, the transmitter transmitting second initial access information for the second service, the second initial access information including a second synchronization channel, the second sub-band being different from the first sub-band.

2. The method of claim 1 , wherein:
the first initial access information includes a first broadcast channel; and
the second initial access information includes a second broadcast channel.

3. The method of claim 2 , wherein:
the first synchronization channel has a different periodicity than the second synchronization channel and the first broadcast channel has a different periodicity than the second broadcast channel.

4. The method of claim 2 , further comprising:
transmitting, in the first sub-band, an indication of a third sub-band to use for ongoing communications for said first service or said second service or said first service and said second service, the third sub-band being different from the first and second sub-bands.

5. The method of claim 4 , wherein the third sub-band is also used for subsequent access for said first service or said second service or said first service and said second service.

6. The method of claim 2 , wherein:
the first initial access information includes a first acknowledgement (ACK)/negative acknowledgement (NACK) channel; and
the second initial access information includes a second ACK/NACK channel.

7. The method of claim 2 , wherein:
the first initial access information includes a first random access channel; and
the second initial access information includes a second random access channel.

8. The method of claim 1 , wherein the first sub-band has a first subcarrier spacing, and the second sub-band has a second subcarrier spacing different from the first subcarrier spacing.

9. The method of claim 1 , wherein the first sub-band is a logical sub-band, and the second sub-band is a logical sub-band.

10. The method of claim 1 , further comprising:
using a first hypercell identifier (ID) for transmissions in the first sub-band; and
using a second hypercell ID for transmissions in the second sub-band, the second hypercell ID being different from the first hypercell ID.

11. The method of claim 1 wherein the first sub-band is associated with the first service, and the second sub-band is associated with the second service.

12. An apparatus comprising a transmitter configured to:
only in a first sub-band predefined for a first service, the first sub-band within a carrier bandwidth, transmit, by the transmitter, first initial access information for a first service, the first initial access information including a first synchronization channel; and
only in a second sub-band predefined for a second service, the second sub-band within the carrier bandwidth, transmit, by the transmitter, second initial access information for a second service, the second initial access information including a second synchronization channel, the second sub-band being different from the first sub-band.

13. The apparatus of claim 12 wherein the at least one transmitter comprises a single transmitter that transmits both the first initial access information and the second initial access information.

14. The apparatus of claim 12 wherein the at least one transmitter comprises a first transmitter that transmits the first initial access information and a second transmitter that transmits the second initial access information.

15. The apparatus of claim 12 , wherein:
the first initial access information includes a first broadcast channel; and
the second initial access information includes a second broadcast channel.

16. The apparatus of claim 15 , wherein:
the first synchronization channel has a different periodicity than the second synchronization channel and the first broadcast channel has a different periodicity than the second broadcast channel.

17. The apparatus of claim 15 , wherein the at least one transmitter is further configured to:
transmit, in the first sub-band, an indication of a third sub-band to use for ongoing communications for said first service or said second service or said first service and said second service, the third sub-band being different from the first and second sub-bands.

18. The apparatus of claim 17 , wherein the third sub-band is also used for subsequent access for said first service or said second service or said first service and said second service.

19. The apparatus of claim 15 , wherein:
the first initial access information includes a first acknowledgement (ACK)/negative acknowledgement (NACK) channel; and
the second initial access information includes a second ACK/NACK channel.

20. The apparatus of claim 15 , wherein:
the first initial access information includes a first random access channel; and
the second initial access information includes a second random access channel.

21. The apparatus of claim 12 , wherein the first sub-band has a first subcarrier spacing, and the second sub-band has a second subcarrier spacing different from the first subcarrier spacing.

22. The apparatus of claim 12 , wherein the first sub-band is a logical sub-band, and the second sub-band is a logical sub-band.

23. The apparatus of claim 12 , wherein the at least one transmitter is further configured to:
use a first hypercell identifier (ID) for transmissions in the first sub-band; and
use a second hypercell ID for transmissions in the second sub-band, the second hypercell ID being different from the first hypercell ID.

24. The apparatus of claim 12 wherein the first sub-band is associated with the first service, and the second sub-band is associated with the second service.
