Abstract: An image processing method includes obtaining a plurality of frames of raw images. After preprocessing such as image alignment, channel splitting or pixel rearrangement is performed on the obtained plurality of frames of raw images, detail restoration is performed on an image based on a deep learning network, and luminance enhancement and color enhancement are performed on an image output by the deep learning network. A plurality of types of processing related to detail restoration are integrated into a same deep learning network.

Abstract: The present disclosure provides a method and apparatus for reference signal configuration. The method includes: determining a time domain density of a phase tracking reference signal (PTRS) according to a first modulation and coding scheme (MCS) and correspondence information between MCSs and PTRS time domain densities; determining a frequency domain density of the PTRS according to a first scheduled bandwidth and correspondence information between scheduled bandwidths and PTRS frequency domain densities; and mapping the PTRS to one or more resource elements (REs) according to the time domain density of the PTRS and the frequency domain density of the PTRS when certain conditions are met.

Abstract: This application discloses a data reporting method, a data receiving method, and related apparatuses. In this application, a terminal device reports, to a network device, one group of information used to indicate scheduling bandwidth thresholds and/or scheduling MCS thresholds. Compared with directly reporting thresholds, in this application, fewer bits can be occupied, thereby reducing overheads.

Abstract: This application provides a communication method and device. The method includes: A terminal device receives a reference signal from a network device, wherein the reference signal is not in a channel state information-reference signal (CSI-RS) resource set, configured with repetition on; and performs radio link monitoring (RLM) measurement or beam failure detection (BFD) measurement on the reference signal. According to the communication method and device provided in this application, the terminal device expects that the resource configured by the network device for performing BFD or RLM is not any resource in the CSI-RS resource set configured with the repetition on.

Abstract: A reference signal sending method and a communications device are provided. The reference signal sending method includes: generating, by a first device, a tracking reference signal, where the tracking reference signal corresponds to a Demodulation Reference Signal (DMRS) port that is used by the first device when the first device sends data to a second device; mapping, by the first device, the tracking reference signal to a time-frequency resource that is used by the first device when the first device sends the data to the second device through the DMRS port, where the tracking reference signal is mapped to at least two modulation symbols on a same frequency resource in one transmission slot; and sending, by the first device, the tracking reference signal mapped to the time-frequency resource to the second device.

Abstract: This application provides a phase tracking reference signal (PTRS) sending method and apparatus. The method includes: implicitly determining, by a terminal device based on obtained uplink grant information and a preset rule, a to-be-sent PTRS and an antenna port for carrying the to-be-sent PTRS, where the antenna port is selected from an antenna port set, and the to-be-sent PTRS is one or more of all available PTRSs; and putting the to-be-sent PTRS on the antenna port, and sending the to-be-sent PTRS on the antenna port. This implicit indication method can effectively reduce air interface signaling overheads and improve air interface efficiency.
