Abstract: In a data processing method performed by a chip comprising a processor and a computing core, the processor receives metadata of first data and metadata of second data. The second data is obtained by performing a first operation on the first data, and memory addresses corresponding to elements at adjacent positions in each row of the second data are discontinuous. The processor compares the metadata of the second data with the metadata of the first data to determine the first operation, and further determines a second operation matching the first operation. The computing core then obtains third data based on the first data and the second operation, wherein memory addresses corresponding to elements at adjacent positions in each row of the third data are continuous.

Abstract: This application has disclosed a method for sending and transmission of a resource conflict indication and a communication apparatus. When determining that a reserved resource indicated by first SCI conflicts with a reserved resource indicated by second SCI, a first terminal device sends an RCI to a second terminal device at a determined time domain and/or frequency domain position before a conflict position; or when determining that a resource corresponding to first SCI conflicts with a resource corresponding to second SCI, a first terminal device sends an RCI to a second terminal device at a determined time domain and/or frequency domain position after a conflict position. The RCI is sent at the determined time domain and/or frequency domain position.

Abstract: Embodiments of this application disclose a reference signal transmission method, a message transmission method, a transmission resource determining method, and an apparatus. When a first device needs to transmit a reference signal, the first device may determine, from a slot and based on a time domain resource parameter of the reference signal, transmission resource information related to a transmission resource used to transmit the reference signal, where the transmission resource information may include a symbol location of the transmission resource in the slot and/or a space domain resource on a symbol in the transmission resource. Compared with a conventional manner in which a reference signal can be transmitted only at a fixed location, the transmission resource for transmitting the reference signal can be dynamically determined based on the time domain resource parameter of the reference signal.

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.
