Method and apparatus for transmitting and receiving feedback in wireless communication system

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• at least one processor configured to:
• receive, from a first time resource, first downlink control information (DCI) including first transmission timing information for feedback,
• receive, on a second time resource, second DCI including second transmission timing information for feedback, and
• transmit, to a base station, feedback information for a data channel scheduled based on the first DCI and a data channel scheduled based on the second DCI, wherein decoding results of the data channel of the first time resource and the data channel of the second time resource are multiplexed in the feedback information based on a time resource indicated by the first transmission timing information identical with a time resource indicated by the second transmission timing information,
• wherein first information associated with a bitmap for the feedback information included in the first DCI is different from second information associated with a bitmap for the feedback information included in the second DCI, based on the time resource indicated by the first transmission timing information identical with the time resource indicated by the second transmission timing information.

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, on a first time resource to a terminal, first downlink control information (DCI) including first transmission timing information for feedback;
• transmitting, on a second time resource to the terminal, second DCI including second transmission timing information for feedback;
• and
• receiving feedback information from the terminal,
• wherein decoding results of a data channel of the first time resource and a data channel of the second time resource are multiplexed in the feedback information and first information associated with a bitmap for the feedback information included in the first DCI is different from second information associated with a bitmap for the feedback information included in the second DCI, based on a time resource indicated by the first transmission timing information identical with a time resource indicated by the second transmission timing information.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• at least one processor configured to:
• transmit, on a first time resource to a terminal via the transceiver, first downlink control information (DCI) including first transmission timing information for feedback,
• transmit, on a second time resource to the terminal via the transceiver, second DCI including second transmission timing information for feedback, and
• receive, from the terminal via the transceiver, feedback information,
• wherein decoding results of a data channel of the first time resource and a data channel of the second time resource are multiplexed in the feedback information and first information associated with a bitmap for the feedback information included in the first DCI is different from second information associated with a bitmap for the feedback information included in the second DCI, based on a time resource indicated by the first transmission timing information identical with a time resource indicated by the second transmission timing information.
