Abstract: A data transmission resource determining method, a device, and a system are applicable to fields such as the Internet of vehicles, intelligent connected vehicles, assisted driving, and intelligent driving, and can improve transmission flexibility and reduce transmission overheads. In this solution, a terminal device determines an initial time interval and an interval difference, and determines, based on the initial time interval and the interval difference, a time domain position of a first time-frequency resource used when a first TB is transmitted for the ith time. The initial time interval is a time interval between a time domain position at which the first TB is transmitted for the first time and a time domain position at which the first TB is transmitted for the second time, and the interval difference is a difference between a first time interval and a second time interval.

Abstract: Embodiments of this application provide a data transmission method, a network device, a communications device, and a storage medium. The method includes: determining, by a network device, a time window of a target communications device group, where a distance between two communications devices in the target communications device group is less than or equal to a threshold, and the time window is used to enable at least two communications devices in the target communications device group to send and receive data in the time window through a sidelink. The network device sends, to the at least two communications devices in the target communications device group, first indication information indicating the time window. The at least two communications devices in the target communications device group are relatively close to a communications device used as a receive end. In this way, mutual interference can be avoided.

Abstract: A random access method, user equipment (UE), a base station, and a random access system, are provided to address relatively long service delay. In various embodiments, after downlink synchronization with a cell is obtained, UE can determine a preamble sequence of the UE in the cell, where the UE has not obtained uplink synchronization with the cell. The UE can then obtain service data and generate a scrambling code, and scramble the service data based on the scrambling code to obtain scrambled service data. The UE can then configure, based on a predetermined resource mapping relationship, time-frequency resources respectively occupied by the preamble sequence and the scrambled service data. The UE then sends on the configured time-frequency resources, the preamble sequence and the scrambled service data to a base station the cell belongs to and receives random access response sent by the base station based on the preamble sequence.

When X resource elements are required for sending first feedback information, and X is less than N, the first terminal apparatus sends at least one piece of SFCI to the second terminal apparatus on the feedback resource through at least one PSFCH. The SFCI includes the first feedback information, and the first feedback information is used to indicate whether the first terminal apparatus correctly receives the first sidelink data.
