Abstract
The present invention relates to a method and a device for same, the method comprising the steps of: receiving control information for disabling at least one among a plurality of hybrid automatic repeat and request (HARQ) processes; receiving a downlink signal on the basis of the control information; and determining whether to perform HARQ feedback for the downlink signal on the basis of a HARQ-acknowledgement (HARQ-ACK) codebook determined on the basis of the control information, wherein the HARQ-ACK codebook is determined on the basis of at least one enabled HARQ process among the plurality of HARQ processes.
Claims12
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving control information for disabling hybrid automatic repeat request (HARQ) feedback for at least one of HARQ process among a plurality of HARQ processes;
- receiving a downlink signal;
- determining a HARQ-acknowledgement (HARQ-ACK) codebook for the downlink signal based on the control information,
- wherein the HARQ-ACK codebook is determined based on enabled HARQ feedback for one or more HARQ process among the plurality of HARQ processes;
- and
- transmitting HARQ-ACK information based on the HARQ-ACK codebook.
A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
- at least one radio frequency (RF) unit;
- at least one processor;
- and
- at least one computer memory operably coupled to the at least one processor and configured to, when executed, cause the at least one processor to perform operations comprising:
- receiving control information for disabling hybrid automatic repeat request (HARQ) feedback for at least one of HARQ process among a plurality of HARQ processes;
- receiving a downlink signal;
- determining a HARQ-acknowledgement (HARQ-ACK) codebook for the downlink signal based on the control information,
- wherein the HARQ-ACK codebook is determined based on enabled HARQ feedback for one or more HARQ process among the plurality of HARQ processes;
- and
- transmitting HARQ-ACK information based on the HARQ-ACK codebook.
A base station configured to operate in a wireless communication system, the base station comprising:
- at least one radio frequency (RF) unit;
- at least one processor;
- and
- at least one computer memory operably coupled to the at least one processor and configured to, when executed, cause the at least one processor to perform operations comprising:
- transmitting control information for disabling hybrid automatic repeat request (HARQ) feedback for at least one of HARQ process among a plurality of HARQ processes;
- transmitting a downlink signal;
- and
- receiving a HARQ-acknowledgement (HARQ-ACK) information for the downlink signal based on a HARQ-ACK codebook determined based on the control information,
- wherein the HARQ-ACK codebook is determined based on enabled HARQ feedback for one or more HARQ process among the plurality of HARQ processes.
