Resource reuse device, user equipment, and resource reuse method

摘要

The present invention discloses a resource reuse apparatus, user equipment, and a resource reuse method, and pertains to the field of communications technologies. The method includes: monitoring, by first user equipment, idle resources so as to obtain a first idle resource set; claiming, in a first cycle, to use a first resource, where the first resource is a resource in the first idle resource set; determining whether the first resource exists in a first claimed resource set, where the first claimed resource set is a set of resources that are claimed to be used by another user equipment except the first user equipment; and if the first resource exists in the first claimed resource set, claiming, in a second cycle, to use a second resource, where the second resource is a resource, in the first idle resource set, that is different from the first resource; or reclaiming a resource after at least one cycle following the first cycle. In the present invention, a probability of a conflict that occurs when user equipment obtains a resource is reduced by determining whether a resource that is claimed by the user equipment is claimed by another user equipment.
