Abstract
An apparatus has one or more memories and one or more processors coupled to the one or more memories. The processor(s) is configured to obtain a first frequency modulated continuous wave (FMCW) waveform having a first center frequency. The first FMCW waveform has a first FMCW signal, and a second FMCW signal that intersects with the first FMCW signal. The processor(s) is also configured to obtain partial information of a cell identifier (ID). The obtaining is associated with a frequency offset between the first center frequency and a synchronization raster frequency. The processor(s) is further configured to perform cell detection based on the partial information of the cell ID.

An apparatus for wireless communication, comprising:
- at least one processor;
- at least one memory coupled with the at least one processor;
- and
- instructions stored in the at least one memory and operable, when executed by the at least one processor, to cause the apparatus to:
- obtain a first frequency modulated continuous wave (FMCW) waveform having a first center frequency and comprising:
- a first FMCW signal,
- and a second FMCW signal that intersects with the first FMCW signal;
- obtain partial information of a cell identifier (ID), the obtaining being associated with a frequency offset between the first center frequency and a synchronization raster frequency;
- and
- perform cell detection based on the partial information of the cell ID.
A method for wireless communication at a wireless node, comprising:
- obtaining a first frequency modulated continuous wave (FMCW) waveform having a first center frequency and comprising:
- a first FMCW signal, and a second FMCW signal that intersects with the first FMCW signal;
- obtaining partial information of a cell identifier (ID), the obtaining being associated with a frequency offset between the first center frequency and a synchronization raster frequency;
- and
- performing cell detection based on the partial information of the cell ID.
A user equipment (UE), comprising:
- at least one transceiver;
- at least one memory comprising instructions;
- and
- at least one processor configured to execute the instructions to cause the UE to:
