Abstract: A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

Abstract: A communication method and a related device are described. A base station includes a plurality of antenna arrays and a baseband processing unit. The plurality of antenna arrays are distributed around a communication area and are all connected to the baseband processing unit. A terminal in the communication area is configured to perform signal transmission with the antenna arrays, to implement communication with the baseband processing unit. When an obstacle exists between the terminal and a primary antenna array performing signal transmission with the terminal, controlling, by the base station through the baseband processing unit, a secondary antenna array to perform signal transmission with the terminal.

Abstract: Embodiments of this application provide a message transmission method, a device, and a system. The method includes: sending an RRC downlink message; preallocating and sending, within a time range of an RRC procedure delay of the RRC downlink message, an uplink grant of an RRC uplink response message corresponding to the RRC downlink message; and receiving, on an uplink resource indicated by the uplink grant, the RRC uplink response message sent by UE from an RRC layer. According to the message transmission method, the device, and the system in the embodiments of this application, a delay generated between receiving the RRC downlink message and feeding back the RRC uplink response message by the UE can be reduced, so that a control plane delay can meet a shorter delay requirement.

Abstract: An antireflection film includes a plurality of convex structures formed on a light transmission surface included in an optical waveguide. A maximum radial length of a surface that is of each convex structure and that is close to the light transmission surface is less than a minimum value of a visible light wavelength. The maximum radial length of each convex structure gradually decreases in a direction away from the light transmission surface. A height of each convex structure is greater than or equal to 310 nm. A distance between geometric centers of surfaces that are of two adjacent convex structures and that are close to the light transmission surface is less than or equal to 220 nm.

Abstract: This application provides example data packet transmission methods and example communications apparatuses. One example method includes receiving a data packet, where the data packet is in an undelivered state. The data packet can then be delivered during running of a reordering timer upon an arrival of a first delay cut-off moment corresponding to the data packet or an arrival of a second delay cut-off moment of an additional data packet before the data packet in a reordering window.
