摘要： A delay budget determining method and apparatus are provided. In technical solutions provided in this application, a communication device first determines a transmission delay of a first data packet from a server to a communication device, and then determines a delay budget of the first data packet from the communication device to a terminal device based on the transmission delay and an end-to-end packet delay budget. In the technical solutions, the delay budget of the first data packet from the communication device to the terminal device is determined based on the transmission delay of the first data packet from the server to the communication device. Therefore, even for an end-to-end delay-sensitive service, a transmission delay of a data packet of the end-to-end delay-sensitive service can also be ensured.

摘要： This application provides a data transmission method and an apparatus, and provides an uplink transmission method for an XR service for XR and video services. In the method, UE notifies a base station that a data flow of a current service has an uplink integrity transmission requirement. The base station maps a QoS flow having the uplink integrity transmission requirement to a corresponding radio bearer, and notifies the UE of the corresponding radio bearer through a signaling configuration. Then, the UE reports, through a MAC CE, a data amount of the service flow having the integrity transmission requirement. According to the method, a loss of a small quantity of data packets in a network transmission process of a data packet having an integrity requirement can be effectively reduced, network uplink transmission efficiency is improved, and user experience of a related service is enhanced.
