Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/164495
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system and, particularly, to a method comprising: a step of decoding CBGs forming a TB; a step of re-receiving the TB after the decoding; and a step of transmitting a plurality of HARQ-ACK bits for the re-receiving of the TB, each HARQ-ACK bit representing a HARQ-ACK response to each CBG of the TB, wherein a HARQ-ACK bit for a first CBG, which was successfully decoded prior to the re-receiving of the TB among the plurality of HARQ-ACK bits, is mapped to an ACK regardless of whether the first CBG is received during the re-receiving of the TB; and to an apparatus therefor.
