摘要： 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.

摘要： 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.

摘要： An information transmission method, is provided, including, a terminal determines attribute information of uplink information based on a beam identifier, and sends the uplink information to a network side device based on the attribute information. After receiving the uplink information, the network side device determines the beam identifier based on the uplink information. In this process, the terminal implicitly indicates beam IDs of different selected beams by using attribute information of reported uplink information. Different beams correspond to different attribute information of the uplink information. In other words, each beam corresponds to specific attribute information of the uplink information. Implicitly indicating a beam ID to the network side device reduces LTE standardization complexity and reduces signaling overheads.

摘要： Embodiments of the present invention provide a control information transmission method, a transmit end, and a receive end. The method includes: determining, by the transmit end, a first time domain resource used for sending scheduled data and a second time domain resource used for sending control information of the scheduled data in a transmission period, where the second time domain resource is a subset of the first time domain resource; and sending, by the transmit end, the control information on the second time domain resource, where the control information includes a parameter used to instruct the receive end to receive the scheduled data. Using the present invention can improve a success rate of data detection, shorten a transmission delay, and further improve reliability of a communications system.
