NETWORK-ASSISTED UE DETECTION IN DIRECT MODE UE-TO-UE COMMUNICATION

摘要

Apparatuses and methods for network-assisted device discovery for device-to- device (D2D) communications are disclosed. In one embodiment, a base station in a cellular communications network receives a D2D request from a first wireless device to establish D2.D communication, in response to the D2D request the base station selects a second wireless device for D2D communication with the first wireless device based on the D2D request and information regarding wireless devices that are available for D2D communication. The base station then transmits a D2D request acknowledgment to the first wireless device that includes information that enables the first wireless device to establish D2D communication with the second wireless device. The base station also effects transmission of a D2D reconfiguration message to the second wireless device, where the D2D reconfiguration message includes information that informs the second wireless device that the first wireless device has requested establishment of D2D communication.
