摘要： 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.

摘要： 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.

摘要： This application provides example uplink carrier handover methods, network devices, and terminal devices. One example method includes obtaining, by a network device, target measurement information, where the network device communicates with a terminal device in a current cell by using a first uplink carrier and a second uplink carrier. The network device can then determine, based on the target measurement information, whether the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier. In response to determining that the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier, the network device can send handover instruction information to the terminal device.

摘要： A buffer status report processing method and an apparatus are disclosed. A network device determines a logical channel or a logical channel group for which a separate buffer status report BSR needs to be reported, and sends separate-BSR reporting indication information. A terminal device receives the separate-BSR reporting indication information sent by the network device, and reports the separate BSR for the logical channel or the logical channel group indicated in the separate-BSR reporting indication information. The network device receives the separate BSR reported by the terminal device, and determines, based on the separate BSR, uplink buffer data amount information corresponding to the logical channel or the logical channel group. According to the BSR processing method, resource scheduling accuracy of the network device is improved.
