Abstract
Provided is a terminal for performing transmission and reception of data in a wireless communication system, wherein the terminal receives, from a base station, first configuration information for code block group (CBG)-based uplink transmission, and second configuration information including a downlink feedback information (DFI) bitmap configuration method, transmits a CBG-based uplink signal to the base station, based on the first configuration information, receives, from the base station, DFI including feedback information about the CBG-based uplink signal, based on the second configuration information, and determines a contention window value of the terminal, based on the feedback information included in the received DFI, wherein the DFI bitmap configuration method indicates whether the feedback information is for feedback in units of transport blocks (TBs) or for feedback for one or more CBGs.
