1. A method, comprising:
sending indication information for a terminal device, wherein the indication information indicates a control channel time-frequency resource unit configuration, and the control channel time-frequency resource unit configuration is one of at least two control channel time-frequency resource unit configurations; and
sending a control channel corresponding to the control channel time-frequency resource unit configuration, wherein
the at least two control channel time-frequency resource unit configurations comprise a first control channel time-frequency resource unit configuration corresponding to a first control channel time-frequency resource unit and a second control channel time-frequency resource unit configuration corresponding to a second control channel time-frequency resource unit, wherein
the first control channel time-frequency resource unit occupies one orthogonal frequency division multiplexing (OFDM) symbol in a time domain, and a demodulation reference signal is carried by the first control channel time-frequency resource unit in the one OFDM symbol, and wherein
the second control channel time-frequency resource unit occupies at least two OFDM symbols in the time domain, and a demodulation reference signal is carried by the second control channel time-frequency resource unit in at least one of the at least two OFDM symbols.
