Abstract: Example communication methods and apparatus are described. One example method includes: when a terminal side device determines that first downlink control information (DCI) meets a first condition, the terminal side device uses a quantity of physical downlink control channel (PDCCH) candidates that are located in a first time unit and that are in a search space set corresponding to the first DCI as a first quantity of times of monitoring. In the first time unit, the terminal side device monitors, in the search space set corresponding to the first DCI based on the first quantity of times of monitoring, a PDCCH carrying the first DCI.

Abstract: An optical communication device includes two optical transmitting devices, two optical receiving devices, an optical path component, and an optical fiber adapter. A first converging lens packaged in each of the optical transmitting devices converges a light beam emitted by a light source, and provides the converged light beam for the optical path component. A second converging lens packaged in each of the optical receiving devices converges a light beam from the optical path component, and provides the converged light beam for a photoelectric detection element. The optical path of the optical communication device is simplified and the process costs are reduced. In addition, the quantity of used lenses is reduced, correspondingly reducing the quantity of optical coupling dimensions between mechanical parts and improving production efficiency of combined passive optical network (Combo PON) products.
