In an implementation, the semi-static UL/DL configuration signaling is RRC signaling or SI.

In an implementation, the dynamic scheduling signaling is DCI and/or a MAC CE.

In an implementation, the transmitting the first channel on the target resource includes:

sending, by the network device, the first channel on the target resource if the transmission direction corresponding to the first channel is a DL direction; or

receiving, by the network device, the first channel on the target resource if the transmission direction corresponding to the first channel is a UL direction.

In an implementation, the transmitting the second channel on the target resource includes:

sending, by the network device, the second channel on the target resource if the transmission direction corresponding to the second channel is a DL direction; or

receiving, by the network device, the second channel on the target resource if the transmission direction corresponding to the second channel is a UL direction.

In an implementation, the transmission unit 803 sends the first channel on the target resource if the transmission direction corresponding to the first channel is a DL direction; or

the transmission unit 803 receives the first channel on the target resource if the transmission direction corresponding to the first channel is a UL direction.

In an implementation, the target resource includes one or more time domain symbols.
