摘要： This application provides a communication method and an apparatus, to help improve transmission efficiency of an uplink XR service. The method includes: A terminal device sends, to a core network device, a first identifier indicating a transmission requirement. Then, the terminal device obtains, based on a first parameter sent by the core network device, a quality of service flow that meets the transmission requirement, and sends a plurality of pieces of first information to an access network device based on the quality of service flow. Each piece of first information includes a second identifier. The second identifier includes marking information of a data unit to which the first information belongs. This method helps a plurality of pieces of first information that belong to a same data unit be considered as a whole for transmission, to improve the transmission efficiency of the uplink XR service.

摘要： This application provides an extended reality data transmission method and an apparatus. The method includes: determining that a data type is extended reality data; determining, based on the data type, to obtain, based on delay information and transmission error information, extended reality quality indicator XQI information corresponding to a target rate, where the XQI information indicates transmission quality of the extended reality data; and performing communication based on the XQI information. Because the XQI information can represent transmission quality of the extended reality XR data in a network, objective impact on the XR data in network transmission can be systematically evaluated by using the method, to guide a network operator to maintain and optimize the network based on a requirement of the XR data.

摘要： Embodiments of this application disclose a processing method, apparatus, and system. The processing method includes: A first terminal obtains a first update request. The first terminal sends a first message to a remote processing center, or the first terminal sends a second message to a local processing center, where both the first message and the second message carry information corresponding to the first update request. The first terminal obtains a fourth message sent by the local processing center, where the fourth message carries second update information obtained after the local processing center performs a preset processing operation on first update information, and the first update information is information obtained by the remote processing center in response to the first message or the third message. The first terminal communicates with the local processing center by using a radio link. The first terminal updates output information of the first terminal based on the second update information carried in the fourth message. In the technical solutions provided in the embodiments of this application, some functions are implemented by using the local processing center. This helps reduce costs of the first terminal.

摘要： This application provides an information transmission method and a communications device. The method includes: when determining that higher layer signaling is not configured with a scrambling identifier, scrambling or descrambling, by a communications device, data by using a second initial scrambling value, where the scrambling identifier is used by the communications device to determine a first initial scrambling value used for data scrambling or descrambling, and the second initial scrambling value is related to at least one or two of a cell identifier, a radio network temporary identifier, and a reserved bit. Therefore, in the embodiments of this application, when determining that the higher layer is not configured with the scrambling identifier, the communications device scrambles or descrambles the data by using the second initial scrambling value. This resolves a problem in the prior art that a terminal device cannot determine an initial scrambling value used for data scrambling.

摘要： This application provides a communication method, a terminal, and a network device. The method includes: receiving, by a terminal, indication information from a network device, where the indication information includes an identifier of at least one reference signal; and determining, by the terminal, that there is a correspondence between a resource used to send a first channel and a first reference signal of the at least one reference signal, where the first channel is a channel to be transmitted by the terminal, and there is a spatial quasi co-location QCL relationship between a port of the first channel and a port of the first reference signal, or there is a spatial QCL relationship between a port of a demodulation reference signal DMRS of the first channel and a port of the first reference signal. In the method, a beam used by the terminal to send the first channel is determined by using the correspondence. Therefore, the method may be applicable to a scenario with beam reciprocity and/or a scenario without beam reciprocity.
