Abstract

Disclosed in the present disclosure is a method by which a terminal receives downlink control information (DCI) in a wireless communication system. In particular, the method is characterized by transmitting at least one configured granted-physical uplink shared channel (CG-PUSCH), transmitting at least one dynamic granted-PUSCH (DG-PUSCH), and receiving DCI comprising a HARQ-ACK bitmap for the at least one DG-PUSCH and the at least one CG-PUSCH, wherein the HARQ-ACK bitmap may comprise N bits, an M bit included in the HARQ-ACK bitmap may be for at least one CG-PUSCH, and an N-M bit included in the HARQ-ACK bitmap may be for the at least one DG-PUSCH.

Claims (32)

1 . A method performed by a user equipment (UE), the method comprising:

transmitting at least one configured granted-physical uplink shared channel;

transmitting at least one dynamic granted-physical uplink shared channel; and

receiving downlink control information including hybrid automatic repeat request (HARQ) information,

wherein the HARQ information includes N HARQ-acknowledgement (ACK) bits,

wherein M HARQ-ACK bits among the N HARQ-ACK bits are for the at least one configured granted-physical uplink shared channel, and the M HARQ-ACK bits are related to at least one configured granted HARQ process, and wherein N-M HARQ-ACK bits are for the at least one dynamic granted-physical uplink shared channel.

2 . The method of claim 1 , wherein each of the N-M HARQ-ACK bits is generated based on logical OR bundling between the at least one dynamic granted-physical uplink shared channel.

3 . The method of claim 1 , wherein each of the M HARQ-ACK bits is generated based on HARQ-ACK information of each of the at least one configured granted-physical uplink shared channel.

4 . The method of claim 1 , wherein each of the M HARQ-ACK bits is generated based on logical AND bundling between the at least one configured granted-physical uplink shared channel.

5 . The method of claim 1 , wherein, based on a time of receiving the downlink control information, HARQ-ACK information for M most recently received configured granted-physical uplink shared channels is mapped to the M HARQ-ACK bits, and

wherein, based on the time of receiving the downlink control information, HARQ-ACK information for N-M most recently received dynamic granted-physical uplink shared channels is mapped to the N-M HARQ-ACK bits.

6 . A user equipment (UE), comprising:

at least one transceiver;

at least one processor; and

at least one memory operatively connected to the at least one processor and configured to store instructions that when executed causes the at least one processor to perform operations,

wherein the operations includes:

transmitting at least one configured granted-physical uplink shared channel;

transmitting at least one dynamic granted-physical uplink shared channel; and

receiving downlink control information including hybrid automatic repeat request (HARQ) information,

wherein the HARQ information includes N HARQ-acknowledgement (ACK) bits,

wherein M HARQ-ACK bits among the N HARQ-ACK bits are for the at least one configured granted-physical uplink shared channel, and the M HARQ-ACK bits are related to at least one configured granted HARQ process, and wherein N-M HARQ-ACK bits are for the at least one dynamic granted-physical uplink shared channel.

7 . The UE of claim 6 , wherein each of the N-M HARQ-ACK bits is generated based on logical OR bundling between the at least one dynamic granted-physical uplink shared channel.

8 . The UE of claim 6 , wherein each of the M HARQ-ACK bits is generated based on HARQ-ACK information of each of the at least one configured granted-physical uplink shared channel.

9 . The UE of claim 6 , wherein each of the M HARQ-ACK bits is generated based on logical AND bundling between the at least one configured granted-physical uplink shared channel.

10 . The UE of claim 6 , wherein, based on a time of receiving the downlink control information, HARQ-ACK information for M most recently received configured granted-physical uplink shared channels is mapped to the M HARQ-ACK bits, and

wherein, based on the time of receiving the downlink control information, HARQ-ACK information for N-M most recently received dynamic granted-physical uplink shared channels is mapped to the N-M HARQ-ACK bits.

11 . A method performed by a base station, the method comprising:

receiving at least one configured granted-physical uplink shared channel;

receiving at least one dynamic granted-physical uplink shared channel; and

transmitting downlink control information including hybrid automatic repeat request (HARQ) information,

wherein the HARQ information includes N HARQ-acknowledgement (ACK) bits,

wherein M HARQ-ACK bits among the N HARQ-ACK bits are for the at least one configured granted-physical uplink shared channel, and the M HARQ-ACK bits are related to at least one configured granted HARQ process, and wherein N-M HARQ-ACK bits are for the at least one dynamic granted-physical uplink shared channel.
