Abstract
The present invention relates to a wireless communication system and, specifically, to a method and an apparatus therefor, the method comprising the steps of: performing a RACH procedure for an initial access; receiving, from a base station, information about an A/N feedback scheme on the basis of the RACH procedure; and performing the A/N feedback procedure on the basis of the information about the A/N feedback scheme.
Claims18
A method for transmitting a Physical Uplink Shared Channel (PUSCH) by an apparatus in a wireless communication system, the method comprising:
- receiving first Downlink Control Information (DCI) scheduling the PUSCH, wherein the first DCI includes information regarding a first total-Downlink Assignment Index (DAI) for a first Physical Downlink Shared Channel (PDSCH) group and information regarding a second total-DAI for a second PDSCH group;
- and
- transmitting the PUSCH based on the first DCI,
- wherein, based on the first total-DAI having a specific value and the second total-DAI not having the specific value, the PUSCH does not include first Hybrid Automatic Repeat Request ACKnowledgement (HARQ-ACK) information related to the first PDSCH group and includes second HARQ-ACK information related to the second PDSCH group.
An apparatus for transmitting a Physical Uplink Shared Channel (PUSCH) in a wireless communication system, the apparatus comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- receiving first Downlink Control Information (DCI) scheduling the PUSCH, wherein the first DCI includes information regarding a first total-Downlink Assignment Index (DAI) for a first Physical Downlink Shared Channel (PDSCH) group and information regarding a second total-DAI for a second PDSCH group;
- and
- transmitting the PUSCH based on the first DCI,
- wherein, based on the first total-DAI having a specific value and the second total-DAI not having the specific value, the PUSCH does not include first Hybrid Automatic Repeat Request ACKnowledgement (HARQ-ACK) information related to the first PDSCH group and includes second HARQ-ACK information related to the second PDSCH group.
A base station configured to receive a Physical Uplink Shared Channel (PUSCH) in a wireless communication system, the base station comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- transmitting first Downlink Control Information (DCI) scheduling the PUSCH, wherein the first DCI includes information regarding a first total-Downlink Assignment Index (DAI) for a first Physical Downlink Shared Channel (PDSCH) group and information regarding a second total-DAI for a second PDSCH group;
- and
- receiving the PUSCH based on the first DCI,
- wherein, based on the first total-DAI having a specific value and the second total-DAI not having the specific value, the PUSCH does not include first Hybrid Automatic Repeat Request ACKnowledgement (HARQ-ACK) information related to the first PDSCH group and includes second HARQ-ACK information related to the second PDSCH group.
