Abstract

A channel sending method and apparatus, and a channel receiving method and apparatus relate to the communications field, where the sending method includes separately setting a repetition quantity and a sending start time of a control channel, and a repetition quantity and a sending start time of a data channel, where the repetition quantity of the control channel is less than the repetition quantity of the data channel or the sending start time of the control channel is earlier than the sending start time of the data channel, sending the control channel according to the repetition quantity and the sending start time of the control channel, and sending the data channel according to the repetition quantity and the sending start time of the data channel. Hence, the sending method can save transmit power and resolve a problem of a lag of data channel demodulation.
