Abstract
The present invention relates to a wireless communication system and, more particularly, to a method and an apparatus therefor, the method comprising the steps of: detecting an SS/PBCH block, wherein the SS/PBCH block includes a PBCH payload and a PBCH DMRS; and on the basis of characteristics of the PBCH DMRS, processing the PBCH payload on the basis of any one from among a plurality of WF methods, wherein the plurality of WFs include at least a CP-OFDM method and a DFT-s-OFDM method.
Claims12
A method of performing communication by a user equipment in a wireless communication system, the method comprising:
- detecting an SS/PBCH (Synchronization Signal/Physical Broadcast Channel) block, the SS/PBCH block including a PBCH payload and a PBCH DMRS (Demodulation Reference signal);
- and
- processing the PBCH payload on the basis of a WF (Waveform) of one of a plurality of WF schemes,
- wherein a plurality of the WF schemes include a CP-OFDM (Cyclic Prefix Orthogonal Frequency Division Multiplexing) scheme and a DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) scheme at least,
- wherein the WF is determined based on characteristics of the PBCH DMRS,
- wherein based on processing the PBCH payload according to the CP-OFDM scheme, a DFT size applied to the PBCH payload is assumed as a value corresponding to a minimum band defined for a synchronization raster having the SS/PBCH block located thereat.
A user equipment used in a wireless communication system, the user equipment comprising:
- at least one processor;
- and
- at least one computer memory operably connected to the at least one processor and enabling the at least one processor to perform an operation when executed, the operation comprising:
- detecting an SS/PBCH (Synchronization Signal/Physical Broadcast Channel) block, the SS/PBCH block including a PBCH payload and a PBCH DMRS (Demodulation Reference signal);
