Method by which terminal transmits feedback signal in wireless communication system, and apparatus therefor
Disclosed are a method by which a terminal transmits a feedback signal in a wireless communication system, and an apparatus therefor, according to various embodiments. Disclosed are the method and an apparatus therefor, the method comprising the steps of: receiving a first signal for scheduling a physical downlink shared channel (PDSCH); and determining whether or not to transmit the feedback signal related to the first signal, wherein, on the basis of the first signal including control information regarding activation or release of a semi-persistent scheduling (SPS) PDSCH, the feedback signal is transmitted regardless of whether or not a hybrid automatic repeat and request (HARQ) process for the PDSCH is disabled.
1 . A method comprising:
receiving information for a semi-persistent scheduling physical downlink shared channel (SPS PDSCH) configuration;
receiving a physical downlink control channel (PDCCH) including downlink control information (DCI);
activating SPS PDSCH receptions related to the SPS PDSCH configuration based on the DCI; and
transmitting an acknowledgement (ACK) or a negative ACK (NACK) for a first SPS PDSCH after the SPS PDSCH receptions are activated, regardless of a hybrid automatic repeat request (HARQ) feedback being disabled for a HARQ process identifier (ID) related to the first SPS PDSCH.
2 . The method of claim 1 , further comprising receiving a configuration of a feedback resource for a disabled HARQ process through radio resource control (RRC) signaling, wherein the ACK or the NACK is transmitted through the feedback resource.
3 . The method of claim 2 , wherein the feedback resource is configured to have a period longer than a period of the SPS PDSCH configuration.
4 . The method of claim 1 , wherein the SPS PDSCH configuration includes a first HARQ process ID pool including enabled HARQ process identifications (IDs) and a second HARQ process ID pool including disabled HARQ process IDs.
5 . The method of claim 1 , wherein the SPS PDSCH configuration is related to a non-terrestrial network (NTN).
6 . A method comprising:
transmitting information for a semi-persistent scheduling physical downlink shared channel (SPS PDSCH) configuration to a user equipment (UE);
transmitting a physical downlink control channel (PDCCH) including downlink control information (DCI) related to an activation of SPS PDSCH receptions related to the SPS PDSCH configuration to the UE; and
receiving, from the UE, an acknowledgement (ACK) or a negative ACK (NACK) for a first SPS PDSCH after the SPS PDSCH receptions are activated, regardless of a hybrid automatic repeat request (HARQ) feedback being disabled for a HARQ process identifier (ID) related to the first SPS PDSCH.
7 . A user equipment (UE) comprising:
a radio frequency (RF) transceiver; and
a processor connected to the RF transceiver,
wherein the processor is configured to:
receive information for a semi-persistent scheduling physical downlink shared channel (SPS PDSCH);
receive a physical downlink control channel (PDCCH) including downlink control information (DCI);
activate SPS PDSCH receptions related to the SPS PDSCH configuration based on the DCI; and
transmit an acknowledgement (ACK) or a negative ACK (NACK) for a first SPS PDSCH after the SPS PDSCH receptions are activated, regardless of a hybrid automatic repeat request (HARQ) feedback being disabled for a HARQ process identifier (ID) related to the first SPS PDSCH.
