It means that data can be transmitted in two directions, but a channel can only be transmitted in one direction at the same time, so it is also called two-way alternate communication. It is impossible to send and receive at the same time. The receiving and sending are time-division. Half-duplex requires that the transceiver can share the same channel, and the data rate is theoretically half of the full-duplex.
