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: A communication method and apparatus. A sidelink resource is determined that meets a quality of service requirement of to-be-transmitted data to improve data transmission efficiency in a 4G system, a 5G system, and/or a future communication system, for example, a 6G system. A first terminal device receives delay information, determines a first packet delay budget, and determines a resource for transmitting data on a sidelink. The delay information indicates a packet delay budget that data transmission is to meet, the first packet delay budget is a packet delay budget that is to be met in response to data being transmitted on the sidelink, and the sidelink is a link for transmitting data between the first terminal device and a second terminal device.

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.
