    Abstract: A method for monitoring a physical downlink control channel (PDCCH) with a discontinuous reception (DRX) related timer by a user equipment (UE) configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process in a wireless communication system is disclosed. Especially, when the UE processes the data block, a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process is started without transmitting the HARQ feedback upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected. Then, while the timer is running, the UE monitors subsequent PDCCHs related to retransmission of the DL HARQ process. Further, when decoding of DL data related to the second PDCCH successes, the timer is stopped and monitoring subsequent PDCCHs for the DL HARQ process is skipped.

    Abstract: The present invention relates to a method of performing uplink transmission by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a configured grant (CG) activation command for a configured uplink grant; based on a size of the configured uplink grant not matching with a size of a pending protocol data unit (PDU) associated with an identified HARQ process, flushing a Hybrid Automatic Repeat Request (HARQ) buffer of the identified HARQ process; and transmitting a CG confirmation medium access control (MAC) control element (CE) using the identified HARQ process.

    Abstract: The present invention relates to a method for performing uplink transmissions by a user equipment in a wireless communication system. In particular, the method includes the steps of: transmitting a data unit to a network using a configured uplink grant; receiving an uplink grant for retransmission of the data unit from the network; determining a retransmission timing using a parameter related to a retransmission delay; and retransmitting the data unit to the network using the uplink grant for retransmission on the determined retransmission timing. Especially, the configured uplink grant is shared by the user equipment and another user equipment, and the parameter indicates at least one instance of retransmission delay.

    Abstract: A method for processing downlink (DL) signals by a user equipment (UE) in a wireless communication system is disclosed. Especially, the UE is configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process. The method comprises steps of upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected, starting a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process, without transmitting the HARQ feedback; and monitoring subsequent PDCCHs related to retransmission of the DL HARQ process while the timer is running.

    Abstract: In the present disclosure, a transmitting device transmits a first message comprising i) a first random access preamble with a first random access preamble identifier (RAPID) and ii) a first uplink payload; receives a random access response (RAR) medium access control (MAC) protocol data unit (PDU) including i) a first field set to represent presence of one or more RAPIDs and ii) the one or more RAPIDs; determines whether both of the first RAP and the first payload is successfully transmitted, based on whether the one or more RAPIDs include the first RAPID; and monitors a second message related to the first message based on determining that both of the first RAP and the first payload is successfully transmitted.
