Abstract

Split synchronization signal configuration for unified synchronization channels and techniques for indicating communication block boundaries in wireless communication systems that use a unified synchronization signal configuration that may be used in different communication modes are described. The disclosed split synchronization signal configuration allows the same synchronization signal configuration to be used in different communication modes (or numerologies) that operate on different frequencies. The boundary indication techniques of embodiments allow efficient indication of the beginning of a communication block (such as a frame, subframe, or slot) relative to the beginning of a unified synchronization signal configuration.

First claim

What is claimed is:

1. A method of wireless communication, comprising:
determining an arrangement of multiple synchronization signals for wireless communication between two or more nodes; and
determining a gap between synchronization signals of the arrangement of multiple synchronization signals to configure the arrangement of multiple synchronization signals for transmission by each communication mode of a plurality of communication modes, wherein each communication mode of the plurality of communication modes implements a different numerology.

2. The method of claim 1 , wherein the different numerology comprises different subcarrier spacing.

3. The method of claim 2 , wherein the different subcarrier spacing of the plurality of communication modes comprises 15 kHz, 30 kHz, and 60 kHz.

4. The method of claim 1 , wherein the gap configures the synchronization signals of the arrangement of multiple synchronization signals to avoid an overlap of any of the synchronization signals of the multiple synchronization signals with another control signal for the wireless communication.

5. The method of claim 1 , wherein the arrangement of multiple synchronization signals has a fixed length in time when used in the plurality of communication modes.

6. The method of claim 1 , wherein the arrangement of multiple synchronization signals includes a primary synchronization signal (PSS).

7. The method of claim 1 , wherein the arrangement of multiple synchronization signals includes a secondary synchronization signal (SSS).

8. The method of claim 1 , wherein the arrangement of multiple synchronization signals includes a reference signal (RS).

9. The method of claim 1 , wherein the arrangement of multiple synchronization signals includes a signal communicated over a physical broadcast channel (PBCH).

10. The method of claim 1 , wherein the arrangement of multiple synchronization signals includes at least two signals selected from the group consisting of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a reference signal (RS), and a signal communicated over a physical broadcast channel (PBCH).

11. An apparatus configured for wireless communication, comprising:
at least one processor; and
a memory coupled to the at least one processor, wherein the at least one processor is configured:
to determine an arrangement of multiple synchronization signals for wireless communication between two or more nodes; and
to determine a gap between synchronization signals of the arrangement of multiple synchronization signals to configure the arrangement of multiple synchronization signals for transmission by each communication mode of a plurality of communication modes, wherein each communication mode of the plurality of communication modes implements a different numerology.

12. The apparatus of claim 11 , wherein the different numerology comprises different subcarrier spacing.

13. The apparatus of claim 12 , wherein the different subcarrier spacing of the plurality of communication modes comprises 15 kHz, 30 kHz, and 60 kHz.

14. The apparatus of claim 11 , wherein the gap configures the synchronization signals of the arrangement of multiple synchronization signals to avoid an overlap of any of the synchronization signals of the multiple synchronization signals with another control signal for the wireless communication.

15. The apparatus of claim 11 , wherein the arrangement multiple synchronization signals has a fixed length in time when used in the plurality of communication modes.

16. The apparatus of claim 11 , wherein the arrangement of multiple synchronization signals includes a primary synchronization signal (PSS).

17. The apparatus of claim 11 , wherein the arrangement of multiple synchronization signals includes a secondary synchronization signal (SSS).

18. The apparatus of claim 11 , wherein the arrangement of multiple synchronization signals includes a reference signal (RS).

19. The apparatus of claim 11 , wherein the arrangement of multiple synchronization signals includes a signal communicated over a physical broadcast channel (PBCH).

20. The apparatus of claim 11 , wherein the arrangement of multiple synchronization signals includes at least two signals selected from the group consisting of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a reference signal (RS), and a signal communicated over a physical broadcast channel (PBCH).
