Abstract
Disclosed is a base station in a wireless communication system. Each base station in wireless communication comprises: a communication module; and a processor. The processor generates a hybrid automatic repeat request (HARQ)-ACK codebook comprising one or more bits and indicating whether or not reception of a channel or signal is successful, and transmits the HARQ-ACK codebook to the base station.

A user equipment in a 3rd generation partnership project (3GPP)-based wireless communication system, the user equipment comprising:
- a communication module;
- and
- a processor configured to control the communication module,
- wherein the processor is configured to:
- receive a plurality of physical downlink control channels (PDCCHs) associated with downlink scheduling, wherein each of the plurality of PDCCHs is received from a respective reception time in a respective cell;
- transmit a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the downlink scheduling on a physical uplink control channel (PUCCH) resource associated with a last PDCCH of the plurality of the PDCCHs,
- wherein the plurality of the PDCCHs is indexed based on a reception time and a cell index associated with each of the plurality of the PDCCHs, and
- wherein, when at least two PDCCHs of the plurality of the PDCCHs have a same reception time and a same cell index, the at least two PDCCHs are indexed further based on a control resource set (CORESET) index associated with each of the at least two PDCCHs.
A method for use by a user equipment in a 3rd generation partnership project (3GPP)-based wireless communication system, the method comprising:
- receiving a plurality of physical downlink control channels (PDCCHs) associated with downlink scheduling, wherein each of the plurality of PDCCHs is received from a respective reception time in a respective cell;
- transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook for the downlink scheduling on a physical uplink control channel (PUCCH) resource associated with a last PDCCH of the plurality of the PDCCHs,
- wherein the plurality of the PDCCHs is indexed based on a reception time and a cell index associated with each of the plurality of the PDCCHs, and
- wherein, when at least two PDCCHs of the plurality of the PDCCHs have a same reception time and a same cell index, the at least two PDCCHs are indexed further based on a control resource set (CORESET) index associated with each of the at least two PDCCHs.
