The method includes: in an unlicensed frequency band of 5G NR, a UE transmitting uplink data and associated UCI to a base station through AUL transmission; the base station identifying the UE through UE specific DMRS; the base station decoding the UCI; if the UCI is successfully decoded, the base station decoding the uplink data; based on whether a transport block or CBG is successfully decoded, the base station transmitting DFI to the UE, the DFI including first information used to indicate a location of the successfully decoded CBG; the UE receiving the DFI; the UE using the first information to determine HARQ-ID of a transport block where the CBG that needs to be retransmitted is located, and a sequence number of the CBG in a HARQ of the transport block where the CBG is located; the UE performing scheduling-free retransmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus, UE, and base station for scheduling-free retransmission for a code block group","description":"UE, base station and data transmission method and apparatus.
