Abstract: A communication method includes: when a network device meets an enabling condition, sending, by the network device, configuration information to a terminal, where the configuration information includes at least one of a type of indication information, a form of the indication information, or a receiving location of the indication information; and sending the indication information to the terminal, where the indication information is used to indicate the terminal whether to monitor a physical downlink control channel PDCCH, or indicate the terminal to monitor a PDCCH, or indicate the terminal not to monitor a PDCCH; or the indication information is used to indicate the terminal whether to receive a physical downlink shared channel PDSCH, or indicate the terminal to receive a PDSCH, or indicate the terminal not to receive a PDSCH. This improves flexibility of using the indication information (for example, a UPSS) by the terminal.
