Abstract: Embodiments of this application provide a resource preemption method, an apparatus, and a system, to reduce a quantity of times of frequent resource preemption, and improve resource security. In one example, a first terminal device obtains a first time interval and a second time interval, and preempts or determines not to preempt a first resource according to a first preset rule. The first resource is a resource reserved by a second terminal device or a resource reserved for a first service to be transmitted by the first terminal device. The first time interval is a time interval related to the first resource. The second time interval is used to indicate a preemption forbidden time. The first preset rule is determined based on the first time interval and the second time interval.

Abstract: This application provides a sidelink configuration method and apparatus, a device, and a storage medium. In one example, before each sidelink transmission is performed, a terminal device at a transmit end sends SCI to a terminal device at a receive end. In this solution, transmission on information needed for sidelink transmissions is performed by using sidelink RRC, so that the terminal device at the receive end obtains a time-frequency resource configuration of sidelink transmissions, and further obtains a HARQ process identifier of each transmission.

Abstract: This application discloses a HARQ process control method and an apparatus, and relates to the field of communications technologies. The method includes: A first terminal apparatus determines that a TB transmitted in a first HARQ process is a first TB transmitted for the last time or a newly transmitted TB; and stops a first timer. Further, the first terminal apparatus sends, to a second terminal apparatus, first indication information used to indicate that the TB transmitted in the first HARQ process is a newly transmitted TB. The second terminal apparatus receives the first indication information, and stops a second timer based on the first indication information.

Abstract: Embodiments of the application provide a sidelink logical channel multiplexing method and apparatus. After determining a first sidelink logical channel (SL LCH) that meets a first preset condition in at least one SL LCH, a terminal allocates a resource to data of the first SL LCH. Then, when a remaining resource of transmission resources is more than zero, the terminal determines, according to a communication range of the first SL LCH, a second SL LCH that meets a second preset condition, and allocates a resource to data of the second SL LCH. The first SL LCH and the second SL LCH are different. In the method, such a parameter as a communication range is considered in a multiplexing process, and data of SL LCHs with same or different communication ranges is multiplexed into a same transport block.
