Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a memory;
a transceiver, and
at least one processor, operably coupled to the memory and the transceiver, configured to:
control the transceiver to receive a synchronization signal/physical broadcast channel block (SSB) from a network;
obtain a master information block (MIB) in the SSB;
control the transceiver to receive, from the network, a system information block 1 (SIB1) based on information included in the MIB for a control resource set (CORESET);
perform an access to a cell related to the network based on access information included in the SIB 1;
control the transceiver to receive a downlink (DL) data from the network;
determine 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, control the transceiver to transmit 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
control the transceiver to transmit an uplink (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.
