Forward compatibility is an important principle in the design of 5G systems. In order to satisfy this principle, an original Common Reference Signal (CRS) based physical downlink control channel for channel estimation in Long-Term Evolution (Long-Term Evolution, LTE for short) occupies the entire system bandwidth, and thus the forward compatibility is very poor and needs to be modified. Similarly, the Physical Uplink Control Channel terminal in 5G can support an Orthogonal Frequency Division Multiplexing (OFDM) waveform mode, and simultaneously support two formats, namely a long format and a short format, and the design of the demodulation reference signal of the Physical Uplink Control Channel (PUCCH) of the original LTE also needs to be modified.
In view of the above problems in the related art, no effective solution has been found so far.

Example 11
The network side (base station or upper network element) determines X first transmission units.
And the base station transmits a control channel to the terminal on the X first transmission units, wherein X is an integer greater than or equal to 1, the first transmission units carry reference signals, each first transmission unit is composed of Y second transmission units, and Y is an integer greater than or equal to 1.
