METHOD AND DEVICE FOR DISCOVERING NEIGHBOR IN DEVICE-TO-DEVICE COMMUNICATION

摘要

Embodiments of the present invention provide a method and a device for discovering a neighbor in device-to-device communication. The method comprises: selecting a pilot sequence from a pilot sequence set; determining a scramble sequence corresponding to the selected pilot sequence according to a preset correspondence between each pilot sequence in the pilot sequence set and the scramble sequence; scrambling user equipment identity information by using the determined scramble sequence; and broadcasting the scrambled user equipment identity information to a neighbor by using a neighbor discovery channel. By using the embodiments of the present invention, conflict interference of multiple user equipments on pilot signals and data signals can be restrained.
