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.

1-20. (canceled)
A user equipment (UE) configured to operate in a 3rd generation partnership project (3GPP) communication system, the UE comprising:
- a communication module;
- and
- a processor for controlling the communication module,
- wherein the processor is configured to:
- receive, from a base station, multiple semi-persistent scheduling physical downlink shared channel (SPS PDSCH) reception configurations, wherein each of the multiple SPS PDSCH reception configurations is associated with a respective SPS PDSCH reception and a respective configuration index,
- receive, from the base station, a single physical downlink control channel (PDCCH) releasing SPS PDSCH receptions, and
- transmit, to the base station, a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook including HARQ-ACK information corresponding to the single PDCCH,
- wherein, in the semi-static HARQ-ACK codebook, the HARQ-ACK information corresponding to the single PDCCH is located at a HARQ-ACK bit position for a SPS PDSCH reception with a lowest configuration index among the SPS PDSCH receptions released by the single PDCCH.
A method for use by a user equipment (UE) in a 3rd generation partnership project (3GPP) communication system, the method comprising:
- receiving, from a base station, multiple semi-persistent scheduling physical downlink shared channel (SPS PDSCH) reception configurations, wherein each of the multiple SPS PDSCH reception configurations is associated with a respective SPS PDSCH reception and a respective configuration index,
- receiving, from the base station, a single physical downlink control channel (PDCCH) releasing SPS PDSCH receptions, and
- transmitting, to the base station, a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook including HARQ-ACK information corresponding to the single PDCCH,
- wherein, in the semi-static HARQ-ACK codebook, the HARQ-ACK information corresponding to the single PDCCH is located at a HARQ-ACK bit position for a SPS PDSCH reception with a lowest configuration index among the SPS PDSCH receptions released by the single PDCCH.
A base station (BS) configured to operate in a 3rd generation partnership project (3GPP) communication system, the BS comprising:
- a communication module;
- and
- a processor for controlling the communication module,
- wherein the processor is configured to:
