Title: DEVICE-TO-DEVICE (D2D) SERVICE TRANSMISSION METHOD, APPARATUS AND DEVICE
Abstract:
Disclosed are a D2D service transmission method, apparatus and device. The method comprises: a UE acquiring signal quality of a first cell located in a first transmission carrier frequency; and when the UE determines that the signal quality of the first cell is higher than a pre-set threshold, and the UE receives first indication information sent by the first cell, the UE selecting the first cell as a serving cell, wherein the first indication information is used for indicating that the first cell can control the UE to transmit device-to-device (D2D) service data on a second transmission carrier frequency, and the first transmission carrier frequency and the second transmission carrier frequency are located at different frequency points. The UE transmits D2D service data by means of the second transmission carrier frequency, thereby solving the problem that a terminal cannot select transmission carrier frequencies located at different frequency points to transmit D2D service data.
