Abstract: The present disclosure provides a terminal and a method performed by the terminal. The terminal is in a communication system, including: a receiving unit that receives timing advance information indicating a first timing advance amount; and a processing unit that acquires a location of the terminal, determines a timing offset based on the location, and determines a terminal-specific timing advance amount based on the first timing advance amount and the timing offset.

Abstract: A data processing method applied to a base station includes: configuring a first transmission resource for a first priority service; when the remaining transmission resources cannot completely bear service data of a second priority service, selecting at least part among the first transmission resource to be configured for a second priority service, the priority of the second priority service being higher than the priority of the first priority service; and sending first downlink control information (DCI), the first DCI being used to indicate the second priority service preempting the transmission resources of the first priority service.
