Claim of US Patent No. 10,973,046

1. A method of receiving a downlink signal by a user equipment in a wireless communication system, the method comprising:detecting, in a frequency band, a physical broadcast channel (PBCH) based on a first subcarrier spacing defined for a frequency range to which the frequency band belongs; and
based on the PBCH carrying information on a second subcarrier spacing, receiving, in the frequency band, a physical downlink shared channel (PDSCH) based on the second subcarrier spacing, the PDSCH carrying system information,
wherein the PBCH carries information explicitly indicating a subcarrier spacing related to a Msg2 of a random access response and a Msg4 of a contention resolution for an initial access, and the subcarrier spacing for the Msg2 is identical to the subcarrier spacing for the Msg4.
