Abstract

A registration method for an optical communication network, an apparatus, a communication device, and a system, relating to the technical field of optical communications. When lowering the transmission power of an optical signal, a first network device generates a registration message according to a determined order, the registration information in the registration message being represented by the order corresponding to an FrFT sequence. Therefore, if a second network device not only receives a service message but also receives the registration message, the second network device can extract, on the basis of the order, the registration information contained in the registration message, so that the second network device can achieve registration (such as going online and ranging) of the first network device according to the registration message. Since the registration message is sent at a low power, the registration message does not affect the transmission of the service message, and the second network device does not need to start a silent window for the registration process of the first network device, thereby avoiding affecting the transmission of service messages of other network devices connected to the second network device, and reducing the overall transmission delay and time jitter of optical communication networks.

Abstract

In accordance with an embodiment, a method includes: accessing, by a first terminal device based on a listen before talk (LBT) process, a channel and determining a channel occupancy time; determining, by the first terminal device, a sidelink resource in the channel occupancy time; and sending, by the first terminal device on the sidelink resource, sidelink information to a second terminal device, or receiving, on the sidelink resource, sidelink information from the second terminal device.

Abstract

A method of decoding includes encountering an end of tile bit with a first value and byte alignment bits in a video bitstream, which indicate that a current coding tree block (CTB) is a last CTB in a tile; encountering an end of CTB row bit with the first value and the byte alignment bits in the video bitstream, which indicate that waveform parallel processing (WPP) is enabled and that the current CTB is the last CTB in a CTB row but not the last CTB in the tile; and reconstructing the plurality of CTBs in the tile based on the end of tile bit with the first value, the end of CTB row bit with the first value, and the byte alignment bits.

Abstract

In the method, an access point AP receives action information separately reported by N stations STAs, where N pieces of action information are used to determine a training result of a first neural network of each STA, and N is a positive integer. The AP determines the training result of the first neural network of each STA based on the N pieces of action information, and sends the training result of the first neural network of each STA to the corresponding STA. The training result of the first neural network of each STA is determined based on the action information reported by the N STAs, instead of only the action information of the STA. This can improve a prediction capability of the first neural network, help improve a capability of each STA to predict channel access behavior of another STA, and improve a system throughput and reduce a communication latency.

Abstract

In one example method, a first image including M objects is obtained. For N objects in the M objects, when N is greater than or equal to 2, arrangement orders of the N objects is determined, where an arrangement order of any one of the N objects is determined based on at least one of a scene intent weight, a confidence score, or an object relationship score. The scene intent weight is used to indicate a probability that the any object is searched in a scene corresponding to the first image, the confidence score is a similarity between the any object and an image in an image library, and the object relationship score is used to indicate importance of the any object in the first image. Search results of some or all of the N objects are fed back according to the arrangement orders of the N objects.
