Abstract

The present disclosure provides an operation method, associated with uplink (UL) transmission, of a terminal in a wireless communication system supporting dynamic resource sharing between an eMBB and a URLLC. More specifically, the method carried out by a terminal comprises receiving, from a base station, a UL grant for scheduling a UL transmission; receiving, from the base station, a control message including first information indicating the stopping of the UL transmission, and second information on a resource for which the UL transmission is to be stopped; and on the basis of the control message, determining whether a demodulation reference signal (DMRS) for the UL transmission is included in the resource for which the UL transmission is to be stopped.

Claims18

Dependent claims

An operation method, associated with uplink (UL) transmission, of a terminal in a wireless communication system supporting dynamic resource sharing between an enhanced Mobile Broad Band (eMBB) and a ultra-reliable low-latency communications (URLLC), the method comprising:

receiving, from a base station, a UL grant for scheduling an uplink resource for the uplink transmission;
receiving, from the base station, downlink control information for indicating cancellation of the uplink transmission on the scheduled uplink resource;
and
determining whether the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource is valid, based on 1) a value of timing advance (TA) related with the terminal, and 2) a timing when the terminal receives the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource,
wherein based on the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource being valid, the uplink transmission on the scheduled uplink resource is canceled, and
wherein based on the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource being invalid, the uplink transmission on the scheduled uplink resource is performed.

A terminal for carrying out uplink (UL) transmission in a wireless communication system supporting dynamic resource sharing between an enhanced Mobile Broad Band (eMBB) and a ultra-reliable low-latency communications (URLLC), the terminal comprising:

a transmitter for transmitting a radio signal;
a receiver for receiving the radio signal;
and
a processor functionally connected to the transmitter and the receiver,
wherein the processor is configured to control:
the receiver to receive, from a base station, a UL grant for scheduling an uplink resource for the uplink transmission;
the receiver to receive, from the base station, downlink control information for indicating cancellation of the uplink transmission on the scheduled uplink resource;
and
to determine whether the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource is valid, based on 1) a value of timing advance (TA) related with the terminal, and 2) a timing when the terminal receives the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource,
wherein based on the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource being valid, the uplink transmission on the scheduled uplink resource is canceled, and
wherein based on the downlink control information for indicating the cancellation of the uplink transmission on the scheduled uplink resource being invalid, the uplink transmission on the scheduled uplink resource is performed.
