Title:

METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA IN A WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2020/235884

Kind Code:

A1

Abstract:

A terminal and a base station in a wireless communication system and a method performed by the terminal and the base station are disclosed. According to an embodiment, the method performed by the terminal in the wireless communication system comprises: receiving a physical downlink control channel (PDCCH), the PDCCH including downlink control information (DCI) for scheduling one or more physical downlink shared channels (PDSCHs); receiving the PDSCHs according to the DCI; and transmitting a hybrid automatic repeat request acknowledgement (HARQ-ACK/NACK) codebook for the PDSCHs.
