Abstract
The present invention relates to a wireless communication system and particularly to a method and a device therefor, the method comprising the steps of: detecting an SSB, the SSB comprising 15 kHz-granularity-based offset information; determining, on the basis of the 15 kHz-granularity-based offset information, a subcarrier offset used to identify the frequency position of a CORESET linked to the SSB; and monitoring, on the basis of the subcarrier offset, the CORESET linked to the SSB.
Claims8
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- detecting a synchronization signal block (SSB), wherein the SSB includes 15 kHz-subcarrier spacing-based offset information;
- based on the 15 kHz-subcarrier spacing-based offset information, determining a value of a subcarrier offset used to identify a frequency location of a control resource set (CORESET) related to the SSB, wherein the 15 kHz-subcarrier spacing-based offset information includes 4 bits of ssb-SubcarrierOffset as least significant bits (LSBs);
- and
- based on the value of the subcarrier offset, monitoring the CORESET related to the SSB,
- wherein, based on the SSB being detected in a shared spectrum, (1) a difference between a synchronization raster in the shared spectrum and a center frequency of the SSB is limited to a multiple of 30 kHz, (2) the value of the subcarrier offset indicates only the multiple of 30 kHz based on the 15 kHz-subcarrier spacing-based offset information, and (3) one LSB of the value of the subcarrier offset is ‘0’.
