Abstract: This application provides a method for sending and receiving control information, an apparatus, and a system. A transmit end sends control information on a data channel, so that a receive end does not need to monitor a control channel through blind detection within a period of time that is after the receive end receives the control information. This can reduce power consumption of the receive end, and also reduce detection complexity caused by blind detection. In addition, attribute information of a demodulation reference signal (DMRS), a start position of a time domain resource and/or a frequency domain resource occupied by the data channel, or a parameter in semi-persistent transmission (SPS) information is used to indicate whether the control information is carried on the data channel. In this way, the receive end can correctly receive the control information, and signaling overheads can be effectively reduced.
