Abstract: The present disclosure relates to mobility management methods and apparatuses. In an example method, a first network device sends conditional handover configuration information of a terminal device to a second network device. After obtaining a mobility report, the first network device sends a first message to the second network device to request the conditional handover configuration information of the terminal device. The first network device receives a response message of the first message from the second network device.

Abstract: The present disclosure provides an encoding and decoding device implementing an improved forward error correction (FEC) coding/decoding method. In particular, the encoding device is configured to encode a stream of data symbols using a spatially coupled code (e.g. staircase codes, braided block codes or continuously interleaved block codes), wherein at least one generalized error location (GEL) code is used as a component code of the spatially coupled code. Accordingly, the decoding device is configured to decode a sequence of encoded symbol blocks using a spatially coupled code, wherein at least one GEL code is used as a component code of the spatially coupled code. Thereby, a suitable spatially coupled FEC code that allows for very low-latency, high-throughput, high-rate applications with a low-complexity decoding procedure, and allows for mitigation of the error-floor, is designed.

Abstract: This application provides a differential pair module, including a first signal terminal and a second signal terminal. The first signal terminal includes a first signal tail part, a first signal body part, and a first signal conductive connection part that are successively connected. An extension plane of the first signal conductive connection part and an extension plane of the first signal body part form an included angle, and an extension direction of the first signal conductive connection part and an extension direction of the first signal tail part form an included angle. The second signal terminal includes a second signal tail part, a second signal body part, and a second signal conductive connection part that are successively connected.

Abstract: A communication method, a communications apparatus, a device, and a communications system. The method includes: a terminal device receives, by using a first beam, broadcast signals broadcast by N network devices, where each broadcast signal includes a current broadcast moment and identification information of a network device that broadcasts the broadcast signal, and N is a positive integer; the terminal device obtains a second beam corresponding to the broadcast signals, where a width of the first beam is greater than that of the second beam; the terminal device measures the broadcast signals of the N network devices by using the second beam corresponding to the broadcast signal; the terminal device obtains, based on a measurement result, a second beam corresponding to a target network device, where the target network device is one of the N network devices.

Abstract: This application provides a random access method and apparatus applicable to satellite communication. The method includes: obtaining a round-trip transmission latency tRTD of a signal between a terminal device and a satellite; obtaining a random access parameter based on the tRTD, where the random access parameter includes one or more of: a duration between a moment at which the terminal device sends a random access preamble and a moment at which the terminal device starts to receive a random access response RAR, a duration of a window in which the terminal device receives the RAR, a duration between a moment at which the terminal device stops receiving the RAR and a moment at which the terminal device sends the random access preamble again, and a subframe duration; and receiving, by the terminal device the RAR based on the random access parameter.

Abstract: This application provides encoding and decoding methods to reduce retransmission in satellite communication. A sending apparatus obtains an information transport block, where the information transport block includes a plurality of code blocks; and generates a redundant code block based on at least two of the plurality of code blocks. The at least two code blocks and the redundant code block are sent over a satellite channel after channel coding. A receiving apparatus receives the to-be-decoded information over the satellite channel, calculates, based on the to-be-decoded information of the at least two code blocks and the redundant code block, an a priori log-likelihood ratio of a to-be-decoded bit, and combines the a priori log-likelihood ratio and a log-likelihood ratio obtained after demodulation, to obtain a diversity gain. Decoding is performed based on the combined log-likelihood ratio. This method improves decoding accuracy and reduces the need for retransmission.
