Abstract: Embodiments of this disclosure relate to the communication field, and provide a data transmission method for short-range wireless communication, and a communication apparatus. The method includes: A first device sends a plurality of first data packets to a second device, where the first device and the second device perform short-range wireless communication. The first device receives a second data packet from the second device, where a first field in the second data packet includes a plurality of indications indicating whether the plurality of first data packets are successfully received. In this manner, when the first device using short-range wireless communication performs data transmission with the second device, the second device respectively indicates, by using the plurality of indications in the second data packet, whether the plurality of first data packets are successfully received, which can avoid frequent switching between sending and receiving, reduce a duration of short-range wireless communication, and improve communication efficiency.

Abstract: The communication method and the communications apparatus may be applied to the internet of vehicles, for example, V2X, LTE-V, and V2V. The method includes: A first terminal apparatus determines a scaling factor based on a subcarrier spacing of a first time-frequency resource to be used to send first data and/or a quantity of slots occupied by the first time-frequency resource. The first data is to-be-sent data of the first terminal apparatus, and the first time-frequency resource occupies a single slot or a plurality of consecutive slots. Then, the first terminal apparatus determines, based on the scaling factor, a size of a transmission block carrying the first data, and sends the transmission block carrying the first data to a second terminal apparatus on the first time-frequency resource.

Abstract: A data processing method and system, and a related device are described. The data processing system includes a processor and a computing core. The method includes the processor receiving metadata of first data and metadata of second data, where the second data is obtained by performing a first operation set on the first data, the first operation set includes at least two first operations, and memory addresses corresponding to elements at adjacent positions in each row of the second data are discontinuous. The processor identifies the first operation set based on the metadata of the second data, and determines a second operation set that matches the first operation set. The computing core obtains third data based on the first data and the second operation set, where memory addresses corresponding to elements at adjacent positions in each row of the third data are continuous.
