Abstract: A delay budget determining method and apparatus are provided. 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. 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.

Abstract: This application provides a data transmission method and an apparatus that are used for extended reality (XR) technologies. In a data transmission method disclosed herein, different parts of to-be-transmitted data are segmented into different code blocks (CBs), to mitigate impact of a transmission failure of one part of the to-be-transmitted data on another part of the to-be-transmitted data, thereby improving overall user experience in data reception. In this way, transmissions of low priority data and high priority data may be separated to avoid performance degradation caused by the low priority data on the high-priority data.

Abstract: A discontinuous reception (DRX) method performed by a terminal, for example, is provided. The method includes starting a DRX on duration timer and monitoring a physical downlink control channel (PDCCH) in a DRX cycle. When the PDCCH indicates that a new data transmission is detected in the DRX cycle, a DRX-inactivity timer is started and the PDCCH is continuing to be monitored. The DRX on duration timer is stopped when at least the DRX-inactivity timer expires while the DRX on duration timer has not yet expired.

Abstract: A communication method and apparatus resolve invalid communication in a packet loss scenario of an XR service, so that device power consumption is reduced, and communication resources are saved. A first communication device obtains information about a data unit to which a data packet belongs, where the data unit includes one or more data packets. The first communication device discards a data packet that is being transmitted and a data packet that is not transmitted that are in the data unit. The first communication device sends indication information to a second communication device, where the indication information includes the information about the data unit.

Abstract: A resource configuration method and a communication apparatus are provided, so that an SPS/CG period can better match an XR service that arrives periodically based on a frame rate, thereby effectively reducing a transmission delay of the XR service and improving system performance. The method includes the following steps: a network device sends first CG configuration information to a terminal. Correspondingly, the terminal receives the configuration information, and obtains first period duration M1 of a first CG period and a quantity X of CGs in the first CG period based on the information, where M1 is greater than zero, and X is an integer greater than zero.

Abstract: An apparatus includes one or more processors that, in response to executing instructions, cause the apparatus to encode a first signal to obtain a first data packet. The first data packet includes first indication information indicating a first tactile sensing threshold. The apparatus is also caused to send the first data packet to a user plane function (UPF) network element. In response to determining the first signal, a second signal, and the first tactile sensing threshold meet a first condition, the apparatus is caused to encode the second signal to obtain a second data packet. The second data packet includes second indication information indicating the first tactile sensing threshold, and the first signal and the second signal correspond to a same tactile flow. The apparatus is additionally caused to send the second data packet to the UPF network element.
