RAT SELECTION FOR DEVICES CAPABLE OF DEVICE-TO-DEVICE (D2D) COMMUNICATION

摘要

Systems and methods for Radio Access Technology (RAT) selection for devices capable of Device-to-Device (D2D) communication are disclosed. In some embodiments, a method of operation of a wireless device in a cellular communications network is provided. The method includes camping on a first cell on a first carrier, where the first cell does not support D2D communication. The method also includes, during a first time interval when the first cell satisfies one or more criteria for the wireless device to remain camped on the first cell, monitoring at least one second carrier on a set of pre-configured radio resources for at least one of the group consisting of: a second cell that supports D2D communication, a signal from a second wireless device that supports D2D communication, and D2D communication.
