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: 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: Embodiments of this application provide a communication processing method for a resource request and a related device. In the communication processing method, a terminal side device sends K uplink resource requests on K (K is an integer greater than or equal to 2) uplink channel resources in a transmission time unit (for example, 1 millisecond) to request an uplink resource used for uplink transmission, where cyclic shifts of a code division multiplexing (CDM) sequence used to send the K uplink resource requests on the K uplink channel resources are specific to the terminal side device, or a value of K is specific to the terminal side device, or a combination of the cyclic shifts and K is specific to the terminal side device.

Abstract: An ephemeris information indication method and an apparatus are provided. In the method, a terminal device receives ephemeris information in a time window, where the ephemeris information corresponds to a system information modification period in which the time window is located. The terminal device determines, based on the system information modification period and a start position of the system information modification period, the system information modification period in which the time window is located. The terminal device determines the ephemeris information reference time based on an end position of a 1st time window in the system information modification period in which the time window is located.

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.
