Abstract: The transmission method includes: transmitting, by a base station, a narrowband physical downlink control channel NB-PDCCH in an nth downlink subframe or a downlink pilot timeslot DwPTS in an nth subframe to a user terminal, where the NB-PDCCH is mapped to an NB-PDCCH mapped basic element, the NB-PDCCH mapped basic element includes a first frequency resource or a second frequency resource in a frequency domain and includes at least one orthogonal frequency division multiplexing OFDM symbol included in the nth downlink subframe or the downlink pilot timeslot DwPTS in the nth subframe in a time domain, a bandwidth of the first frequency resource is less than or equal to 180 kHz, the second frequency resource is a frequency resource included in a resource block RB, and n≥1.
