摘要： The present disclosure relates to list decoding that uses a graph representation of an Error Correcting Code (ECC) and provides early list size reduction. The list decoding involves reducing a size of a list of codeword candidates for a received codeword after a minimum number of decoding iterations, and using machine learning means to improve a rule for selecting the most relevant codeword candidate for the received codeword. At the same time, the iterative decoding is performed by using the graph representation for the ECC by which the received codeword has been obtained. By so doing, it is possible to reduce the overall list-based decoding complexity and achieve acceptable decoding performance for bigger sizes of the list of codeword candidates at lower computational costs. Moreover, such graph-based list decoding may efficiently be used for decoding codewords obtained by using different ECCs, including (but not limited thereto) low-density parity-check codes.

摘要： Embodiments of this application provide a data transmission method and apparatus. The method includes: A transmit device calculates an original priority of proportional-fair PF scheduling of a target logical channel; the transmit device calculates a priority modification factor of the target logical channel based on whether a first packet in a current minimum effective transmission unit METU that is being sent on the target logical channel has left a buffer queue; the transmit device performs weighting on the original priority of the target logical channel by using the priority modification factor, to obtain a modified priority of the target logical channel; and the transmit device schedules the target logical channel based on the modified priority. The data transmission method according to embodiments of this application may be used, for example, in a cloud VR service scenario in which HEVC coding is used, and weighting is performed on a logical channel for transmitting cloud VR service data, to accelerate a transmission speed of the cloud VR service data, thereby improving integrity of cloud VR data transmission when an extremely low air interface delay requirement is met.

摘要： This application provides a data transmission method and an apparatus. In the technical solutions of this application, a transmission priority of a data packet may be changed, so that the data packet has an opportunity to continue to be transmitted. Specifically, when the data packet just arrives at a PDCP layer of a communication apparatus, the priority of the data packet is a specific priority. If the data packet is not sent or is not successfully sent after a decoding moment of a receiver is exceeded, compared with a manner of directly discarding the data packet, in this manner, the priority of the data packet may be changed, so that the data packet has the opportunity to continue to be transmitted. This helps improve a compression rate and a decoding effect, to improve user experience.

摘要： Embodiments of this application provide a resource scheduling method and apparatus. The method includes: receiving a first coded frame; determining a remaining delay budget of the first coded frame based on an actual time point at which the first coded frame arrives at a first network element; determining a scheduling priority based on the remaining delay budget; and scheduling, for the first coded frame based on the scheduling priority, a transmission resource for transmitting the first coded frame. When the scheduling priority is less than or equal to a preset priority threshold, the transmission resource is preferentially scheduled for the first coded frame. When the scheduling priority is greater than the preset priority threshold, a delay of the first coded frame is increased. In this way, resources can be flexibly scheduled for a coded frame that arrives at the first network element in advance and a coded frame that is delayed to arrive at the first network element, to alleviate phenomena such as frame freezing, lagging, and frame skipping caused by network jitter in a coded stream transmission process, reduce poor experience such as image tearing and flicker, and help improve user interaction experience.
