Abstract: This application discloses a data transmission method and apparatus, and UE, and pertains to the field of communications technologies, so as to resolve the problem that the UE cannot determine how to perform repetition transmission because repetition transmission is configured to be performed within the idle period of the FFP. The method includes: in a case that a time-domain resource of first data overlaps with a first idle period, transmitting, by UE, first data according to a first transmission rule; where the first data is data for repetition transmission, the first idle period is an idle period of a first FFP, and the first FFP is an FFP used by the UE.

Abstract: A data transmission method and apparatus for an unlicensed band, and a communication device are provided. The data transmission method, performed by a terminal, includes: performing uplink transmission based on Fixed Frame Period (FFP) configuration information and a channel state. The FFP configuration information includes at least one of an FFP start location or an FFP length of the terminal, and at least one of an FFP start location or an FFP length of a network-side device. The FFP start location of the terminal is different from the FFP start location of the network-side device.
