The present invention provides a transmission method and apparatus in a TDD-FDD joint system. In an embodiment of cross-carrier scheduling, an HARQ time sequence of a PUSCH on a scheduled CC complies with a time sequence of a TDD system, and an HARQ time sequence of a PDSCH on the scheduled CC complies with a time sequence of an FDD system; if an uplink reference frame structure on the scheduled CC is #0, uplink-scheduling DCI of the scheduled CC comprises ULI/DAI bits; and if the uplink reference frame structure on the scheduled CC is one of #1 to #6, the uplink-scheduling DCI of the scheduled CC does not comprise the ULI/DAI bits. By using the technical solutions provided in the present invention, redundant overheads of the DCI are reduced, the coverage of the DCI is enlarged, and meanwhile, the compatibility with an existing system is kept to the greatest degree in the present invention.

Transmission method and apparatus in TDD-FDD joint system

The invention provides a solution for Discovery Signal (DS) in the device-to-device (D2D) communication, and includes a UE device and a method therefor. In an embodiment, the UE sends a DS to indicate configuration information through which a D2D communication connection can be established. The configuration information is suitable for a DS with a bit of information or a DS with a sequence. Through the technical solution provided in the invention, configuration information indicated by a DS can be minimized and the requirement of establishing a D2D communication connection can be satisfied in the meantime.
