Downlink control channel monitoring method and apparatus

An apparatus comprising:

• one or more processors;
• and
• a non-transitory computer readable medium storing instructions that, when executed by the one or more processors, cause the apparatus to:
• send first indication information to a network device, the first indication information indicating N groups of monitoring capability parameters of a terminal device, each group of monitoring capability parameters comprising a reference value of an interval between monitoring spans and a reference value of duration of a monitoring span, N being a positive integer, and a monitoring capability comprising at least one of a maximum quantity of candidate downlink control channels and a maximum quantity of non-overlapping control channel elements;
• determine at least one of K monitoring spans in a first time unit based on reference values of intervals between monitoring spans and reference values of duration of monitoring spans in the N groups of monitoring capability parameters, where K is a positive integer;
• determine monitoring capabilities in the K monitoring spans based on reference values of monitoring capabilities in monitoring spans in the N groups of monitoring capability parameters;
• and
• perform blind detection on a downlink control channel in at least one of the K monitoring spans based on the monitoring capabilities in the K monitoring spans.
