Physical downlink control channel PDCCH transmission method and apparatus

A communication apparatus, comprising:

• a transceiver configured to send first indication information to a terminal device, wherein the first indication information comprises configuration information of a physical downlink control channel (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,
• wherein the transceiver is further configured to send the PDCCH to the terminal device in the first repeated transmission configuration manner, including separately sending, the PDCCH at n time-frequency resource positions, and
• 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.

A communication apparatus, comprising:

• a transceiver, configured to receive first indication information from a network device, wherein the first indication information comprises configuration information of a physical downlink control channel (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,
• wherein the transceiver is further configured to receive, in each repeated transmission configuration manner, the PDCCH sent by the network device, wherein the PDCCH is sent in the first repeated transmission configuration manner, including the PDCCH being sent separately, at n time-frequency resource positions, and
• 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.
