Method for generating HARQ-ACK codebook in wireless communication system and device using same
View Patent ↗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. A device for use in a wireless communication system, the device comprising:
a memory; and
a processor connected to the memory and configured to:
configure receptions of multiple semi-persistent scheduling physical downlink shared channels (SPS PDSCHs); and
transmit a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook including HARQ-ACK bits related to the multiple SPS PDSCHs,
wherein, based on a physical downlink control channel (PDCCH) indicating a release of the multiple SPS PDSCHs being associated with the semi-static HARQ-ACK codebook, HARQ-ACK information for the PDCCH is located at a bit position for one of the multiple SPS PDSCHs in the semi-static HARQ-ACK codebook, based on indexes related to the multiple SPS PDSCHs.
2. The device of claim 1 , wherein a plurality of candidate receptions for the semi-static HARQ-ACK codebook is defined based on a set of PDSCH-to-physical uplink control channel (PUCCH) slot timing values.
3. The device of claim 1 , wherein the semi-static HARQ-ACK codebook has a pre-defined size.
4. The device of claim 1 , wherein the semi-static HARQ-ACK codebook is transmitted through a physical uplink control channel (PUCCH).
5. A method for use in a wireless communication system, the method comprising:
configuring receptions of multiple semi-persistent scheduling physical downlink shared channels (SPS PDSCHs); and
transmitting a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook including HARQ-ACK bits related to the multiple SPS PDSCHs,
wherein, based on a physical downlink control channel (PDCCH) indicating a release of the multiple SPS PDSCHs being associated with the semi-static HARQ-ACK codebook, HARQ-ACK information for the PDCCH is located at a bit position for one of the multiple SPS PDSCHs in the semi-static HARQ-ACK codebook, based on indexes related to the multiple SPS PDSCHs.
6. The method of claim 5 , wherein a plurality of candidate receptions for the semi-static HARQ-ACK codebook is defined based on a set of PDSCH-to-physical uplink control channel (PUCCH) slot timing values.
7. The method of claim 5 , wherein the semi-static HARQ-ACK codebook has a pre-defined size.
8. The method of claim 5 , wherein the semi-static HARQ-ACK codebook is transmitted through a physical uplink control channel (PUCCH).
9. A device for use in a wireless communication system, the device comprising:
a memory; and
a processor connected to the memory and configured to:
configure transmissions of multiple semi-persistent scheduling physical downlink shared channels (SPS PDSCHs); and
receive a semi-static hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook including HARQ-ACK bits related to the multiple SPS PDSCHs,
wherein, based on a physical downlink control channel (PDCCH) indicating a release of the multiple SPS PDSCHs being associated with the semi-static HARQ-ACK codebook, HARQ-ACK information for the PDCCH is located at a bit position for one of the multiple SPS PDSCHs in the semi-static HARQ-ACK codebook, based on indexes related to the multiple SPS PDSCHs.
10. The device of claim 9 , wherein a plurality of candidate transmissions for the semi-static HARQ-ACK codebook is defined based on a set of PDSCH-to-physical uplink control channel (PUCCH) slot timing values.
11. The device of claim 9 , wherein the semi-static HARQ-ACK codebook has a pre-defined size.
12. The device of claim 9 , wherein the semi-static HARQ-ACK codebook is received through a physical uplink control channel (PUCCH).
13. A method for use in a wireless communication system, the method comprising:
configuring transmissions of multiple semi-persistent scheduling physical downlink shared channels (SPS PDSCHs); and
