Abstract
Systems, methods, and apparatuses for initiating device-to-device (D2D) communication in wireless communication networks are provided. Based on received downlink or uplink signal qualities, a two-stage process, that is, a first stage of information request and a second stage of actual information transfer, may be used to initiate the D2D communication. Multiple thresholds, timers, and/or counters may be used in connection with the two-stage process. The two-stage process reduces unnecessary signaling overhead for initiating the D2D communication.
