1. A physical downlink control channel (PDCCH) transmission method, comprising:
sending, by a network device, first indication information to a terminal device, wherein the first indication information comprises configuration information of a PDCCH, the configuration information indicates at least one repeated transmission configuration manner, and the at least one repeated transmission configuration manner comprises a first repeated transmission configuration manner comprising a quantity of n repetitions of the PDCCH, wherein n is an integer greater than or equal to 2; and
sending, by the network device, the PDCCH to the terminal device in the first repeated transmission configuration manner, including separately sending, the PDCCH at n time-frequency resource positions,
wherein each repeated transmission configuration manner comprises at least one of a quantity of repetitions of the PDCCH or an aggregation level of the PDCCH and that corresponds to the quantity of repetitions.
