Abstract
A default subcarrier spacing for use in transmission/reception of a broadcast channel is defined for each frequency range. A base station transmits a broadcast channel in a frequency band, using the default subcarrier spacing defined for a frequency range to which the corresponding frequency band belongs. A user equipment attempts to detect a broadcast channel in the frequency band where a cell search is being attempted, using the default subcarrier spacing defined for a frequency range to which the frequency band belongs.
Claims8
A method performed by a user equipment in a wireless communication system, the method comprising:
- receiving a synchronization signal/physical broadcast channel (SS/PBCH) block based on a first subcarrier spacing,
- wherein the first subcarrier spacing is based on each of frequency ranges, and
- wherein the SS/PBCH block includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a PBCH;
- and
- receiving a physical downlink shared channel (PDSCH) based on one of second subcarrier spacings,
- wherein the PBCH carries information related to the one of second subcarrier spacings per each of the frequency ranges, and
- wherein a same subcarrier spacing is configured for the PSS, the SSS, and the PBCH.
A user equipment in a wireless communication system, the user equipment comprising:
- a transmitter;
- a receiver;
- and
- at least one processor coupled with the transmitter and the receiver,
