Abstract: A data transmission method and an apparatus. A transmission priority of a data packet may be changed so that the data packet has an opportunity to continue to be transmitted. when the data packet just arrives at a PDCP layer of a communication apparatus, and the priority of the data packet is an initial 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.

Abstract: Embodiments of this application disclose example data transmission methods and example communication apparatuses. One example method includes receiving, by a first core network function entity, multi-stream transmission information of a service, where the multi-stream transmission information indicates that the service is transmitted via first split data and second split data. The first core network function entity can then receiver, based on the multi-stream transmission information, first quality of service QoS configuration information and second QoS configuration information, where the first QoS configuration information corresponds to the first split data, and the second QoS configuration information corresponds to the second split data. The first core network function entity can then output the first QoS configuration information and the second QoS configuration information.

Abstract: This disclosure provides a decoding method and apparatus in the communications field. The method includes: extracting at least one piece of prior information from at least one first transport block that has been successfully decoded, and assembling the at least one piece of prior information into a prior information set, where one piece of prior information includes header information of a transmission protocol layer of one first transport block; when a to-be-decoded second transport block sent by a transmit end is received, selecting first prior information from the prior information set, where the second transport block is a transport block obtained by the transmit end by coding a third transport block; and decoding the second transport block based on the first prior information and first demodulation information of the second transport block, to obtain the third transport block.

Abstract: A target service management method is provided. The method is applicable to services such as a voice call, a video call, video livestreaming, Cloud AR/VR, and tactile Internet. The method includes: An access network device determines key quality indicator KQI information of a target service during transmission of the target service on a target channel; and manages, based on the KQI information and a target service quality-of-service requirement corresponding to the KQI information, the target service. In this way, the access network device can manage the target service based on the quality of service of the target service and can improve effective utilization of an air interface resource of the access network device in transmitting the target service, and can further increase a capacity of users whose quality of service satisfies a requirement in a system.

Abstract: A data transmission method includes receiving, by a network device, a tactile data flow and at least one first data flow sent by a machine-side device. The tactile data flow and the at least one first data flow includes a synchronization identifier. The data transmission method also includes synchronizing, by the network device, transmission time of the tactile data flow and transmission time of the at least one first data flow.

Abstract: 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.
