Abstract: A data sending apparatus includes a processor and a transceiver. The processor is configured to generate K first frequency-domain data streams, wherein a kth first frequency-domain data stream of the K first frequency-domain data streams is determined by performing preprocessing on a kth first modulated data stream, and the preprocessing includes at least a Fourier transform, a cyclic extension, or a phase rotation. The processor is further configured to map the K first frequency-domain data streams to frequency-domain resources to generate a time-domain symbol, and the transceiver is configured to send the time-domain symbol. A length of the kth first frequency-domain data stream of the K first frequency-domain data streams is Nk, and a length of the kth first modulated data stream is Mk. K is a positive integer greater than 1, Nk and Mk are positive integers, and k is an integer k=0, 1, . . . , K−1.

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: 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.

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.

Abstract: The present disclosure relates to data transmission methods and apparatus. In one example method, a first terminal device receives downlink control information (DCI) from a network device, where the DCI is used to schedule uplink transmission or sidelink transmission, and the DCI indicates data transmission of the first terminal device or the first terminal device to assist in forwarding data of a second terminal device. The first terminal device performs the uplink transmission or the sidelink transmission based on the DCI.

Abstract: A data transmission method and apparatus, and a related device, and may be used in the internet of vehicles, for example, V2X, LTE-V, or V2V, or may be used in fields such as D2D, intelligent driving, and intelligent connected vehicle. A network device may send first downlink control information to a first terminal device and a second terminal device, to indicate the first terminal device and the second terminal device to perform user cooperative transmission in a first stage. After the transmission in the first stage is completed, the network device sends second downlink control information to the first terminal device and the second terminal device, to indicate the first terminal device and the second terminal device to perform user cooperative transmission in a second stage. The network device uses a two-level scheduling manner to improve transmission efficiency in the second stage.
