摘要： Embodiments of the present invention provide synchronization signal sending and receiving methods, apparatuses, and devices. The synchronization signal sending apparatus of the present invention includes: a synchronization signal generation module, configured to generate a synchronization signal according to one or more sequences, where a length or lengths of the one or more sequences are determined according to a length of the synchronization signal; a baseband signal obtaining module, configured to obtain a baseband signal according to the synchronization signal generated by the synchronization signal generation module; and a first sending module, configured to send, after performing radio frequency conversion, out the baseband signal obtained by the baseband signal obtaining module. In a D2D communication scenario, a value of cross-correlation between synchronization signals provided in the embodiments of the present invention is small, which can reduce synchronization detection time. Therefore, a receive end of the synchronization signals can implement quick synchronization with a transmit end according to the synchronization signals, thereby improving system performance.

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.
