Abstract
A method by which a terminal transmits uplink control information (UCI) in an unlicensed band and a device using the method are provided. The method generates data and first UCI including information necessary to decode the data, and transmits, to a base station, the data and the first UCI through a physical uplink shared channel (PUSCH) in an unlicensed band, wherein the first UCI further includes information necessary to decode the second UCI when second UCI is transmitted to the base station together with the data and the first UCI through the PUSCH.
Claims11
A method of performing a hybrid automatic repeat request (HARD) process by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving resource allocation information informing of resources which can be used for transmitting a physical uplink shared channel (PUSCH);
- receiving time information related to a duration between a transmission of the PUSCH and a reception of downlink feedback information (DFI) including HARQ-ACK (acknowledgement) information for the PUSCH;
- transmitting the PUSCH through a first resource among the resources without receiving a dynamic grant for the PUSCH;
- and
- receiving the DFI including the HARQ-ACK information for the PUSCH through a second resource located after the duration from the first resource,
- wherein the duration is dependent on a configured subcarrier spacing.
A user equipment (UE), the UE comprising:
- a transceiver;
- and
- a processor, operably coupled to the transceiver,
- wherein the processor is configured to:
- receive resource allocation information informing of resources which can be used for transmitting a physical uplink shared channel (PUSCH);
- receive time information related to a duration between a transmission of the PUSCH and a reception of downlink feedback information (DFI) including HARQ-ACK (acknowledgement) information for the PUSCH;
- transmit the PUSCH through a first resource among the resources without receiving a dynamic grant for the PUSCH;
- and
- receive the DFI including the HARQ-ACK information for the PUSCH through a second resource located after the duration from the first resource,
- wherein the duration is dependent on a configured subcarrier spacing.
A processor for a wireless communication device in a wireless communication system,
- wherein the processor is configured to control the wireless communication device to:
- receive resource allocation information informing of resources which can be used for transmitting a physical uplink shared channel (PUSCH);
- receive time information related to a duration between a transmission of the PUSCH and a reception of downlink feedback information (DFI) including HARQ-ACK (acknowledgement) information for the PUSCH;
- transmit the PUSCH through a first resource among the resources without receiving a dynamic grant for the PUSCH;
- and
- receive the DFI including the HARQ-ACK information for the PUSCH through a second resource located after the duration from the first resource,
- wherein the duration is dependent on a configured subcarrier spacing.
