Abstract: A communication method and apparatus are provided. The communication method includes: A terminal receives, from a network device, configuration information indicating a first time-frequency resource and downlink control information indicating a second time-frequency resource. The first time-frequency resource cannot be used to transmit a downlink data channel and a demodulation reference signal for the downlink data channel, and the second time-frequency resource includes a resource used to transmit the downlink data channel and the demodulation reference signal for the downlink data channel. When determining that a time domain resource of the first time-frequency resource includes a time domain resource of the second time-frequency resource, the terminal receives the downlink data channel and the demodulation reference signal for the downlink data channel on a third time-frequency resource.
