TRANSMISSION METHOD, USER EQUIPMENT, AND BASE STATION FOR D2D COMMUNICATION

摘要

Provided in embodiments of the present invention are a transmission method, user equipment, and base station for D2D communication. The user equipment employs an OFDM signal modulation scheme for an uplink time-frequency resource or employs an SC-FDM signal modulation scheme for a downlink time-frequency resource to conduct D2D communication. The method comprises: a user equipment either aligns a subcarrier center of a D2D communication signal that employs an OFDM signal modulation scheme with a subcarrier center of an uplink time-frequency resource signal or aligns a subcarrier center of a D2D communication signal that employs an SC-FDM signal modulation scheme with a subcarrier center of a downlink time-frequency resource signal. The embodiments of the present invention allow a signal of D2D communication to remain orthogonal with a signal of an uplink time-frequency resource and prevents mutual aliasing that affects the quality of communication.
