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.

Abstract: This application provides example downlink control information transmission methods and apparatuses. In an example method, a terminal device receives first configuration information. The first configuration information may indicate the terminal device to monitor a physical downlink control channel (PDCCH) candidate in a first scheduling cell and a second scheduling cell. The PDCCH candidate is used to carry downlink control information for scheduling data transmission in a same scheduled cell. The terminal device determines, for the same scheduled cell, monitoring upper limits of the PDCCH candidate in a first unit time and a second unit time. The first unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the first scheduling cell, and the second unit time is determined based on a subcarrier spacing of an active downlink bandwidth part in the second scheduling cell.

Abstract: This application provides a communication method and a communications apparatus. A terminal may perform, based on first configuration information for a maximum of a first quantity of times, blind detection at PDCCH candidate locations configured by a network device for a first CORESET group. In comparison with a solution, in the conventional technology, in which the terminal blindly detects a PDCCH for all CORESETs in a target cell for a maximum of the first quantity of times, blind detection is performed for a CORESET corresponding to each TRP for a larger quantity of times. Therefore, scheduling flexibility can be improved.
