Abstract: Embodiments of this application provide a downlink control channel monitoring method and apparatus. A terminal device sends N groups of blind monitoring capability parameters to a network device. The monitoring capability parameters include: a reference value of an interval between monitoring spans, a reference value of duration of a monitoring span, and a reference value of a monitoring capability in the monitoring span. The terminal device determines K monitoring spans in a slot based on the N groups of monitoring capability parameters, and allocates a monitoring capability of the terminal device to the K monitoring spans based on the N groups of monitoring capability parameters. The terminal device may further perform blind detection on a downlink control channel in the K monitoring spans based on monitoring capabilities in the K monitoring spans.
