the third determining unit 305 is configured to determine a direction of the target resource as a DL transmission direction; and

the transmission unit 306 is configured to receive DL data on the target resource.

In the foregoing solution, the target resource includes one or more symbols.

A person skilled in the art should understand that for the implementation functions of the units in the transmission direction determining apparatus shown in FIG. 3, refer to the related description of the foregoing transmission direction determining method. The functions of the units in the transmission direction determining apparatus shown in FIG. 3 may be implemented by a program running on a processor or may be implemented by a specific logic circuit.

FIG. 4 is a schematic structural diagram 2 of a transmission direction determining apparatus according to an embodiment of this application. As shown in FIG. 4, the apparatus includes:

a first configuration unit 401, configured to configure and send first configuration signaling, where the first configuration signaling is used to indicate that a target resource corresponds to a first transmission direction, and the first configuration signaling is cell-specific RRC signaling;

a second configuration unit 402, configured to configure and send second configuration signaling, where the second configuration signaling is used to indicate that the target resource corresponds to a second transmission direction; and
