Abstract
Certain aspects of the present disclosure provide techniques for signaling what sync rasters via different types of patterns. In some cases, a network entity (e.g., a gNB) may indicate a sync raster by transmitting a pattern formed by a first signal associated with a frequency that increases in time for at least a first duration according to a first slope and a second signal associated with a frequency that decreases in time for at least a second duration according to a second slope. Different patterns may map to different sync rasters. Thus, a user equipment (UE) may scan for synchronization signals according to a sync raster associated with a detected pattern.
Claims20
An apparatus for wireless communication, comprising:
- at least one memory comprising computer-executable instructions;
- and
- one or more processors configured to execute the computer-executable instructions to cause the apparatus to:
- obtain a signal associated with a pattern formed by a first signal associated with a frequency that increases in time for at least a first duration according to a first slope and a second signal associated with a frequency that decreases in time for at least a second duration according to a second slope;
- and
- scan for a synchronization signal (SS) based on a synchronization raster associated with the pattern.
An apparatus for wireless communication, comprising:
- at least one memory comprising computer-executable instructions;
- and
- one or more processors configured to execute the computer-executable instructions to cause the apparatus to:
- output a signal associated with a pattern formed by a first signal associated with a frequency that increases in time for at least a first duration according to a first slope and a second signal associated with a frequency that decreases in time for at least a second duration according to a second slope;
- and
- output one or more synchronization signals (SSs) based on a synchronization raster associated with the pattern.
A method for wireless communication at a wireless node, comprising:
- obtaining a signal associated with a pattern formed by a first signal associated with a frequency that increases in time for at least a first duration according to a first slope and a second signal associated with a frequency that decreases in time for at least a second duration according to a second slope;
- and
- scanning for a synchronization signal (SS) based on a synchronization raster associated with the pattern.
