Claim 0:
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a synchronization signal/physical broadcast channel block (SSB) from a network;
obtaining a master information block (MIB) in the SSB;
receiving, from the network, a system information block 1 (SIB1) based on information included in the MIB for a control resource set (CORESET);
performing an access to a cell related to the network based on access information included in the SIB1;
receiving a downlink (DL) data from the network;
determining an acknowledgement/negative-acknowledgement (ACK/NACK) transmission timing as a timing after a predetermined time interval from an end of a reception of the DL data;
based on that a processing time of the DL data is less than the predetermined time interval minus an offset, transmitting an ACK/NACK for the DL data to the network by applying the offset to a timing advance (TA) so that the ACK/NACK is transmitted at the offset earlier than the ACK/NACK transmission timing; and
transmitting an UL data to the network by applying the offset to the TA after transmitting the ACK/NACK,
wherein the offset is configured by the network.
