Abstract: A method is performed by a system of a wireless communication network, for detecting neighboring UEs of a first UE that is wirelessly connected to a first base station. The method includes receiving power measurements performed on signals received at the first UE, which signals are sent from base stations, each power measurement being associated with an ID of the base station from which the signal was sent. The method further includes receiving power measurements of signals received at a second UE that is wirelessly connected to a second base station, each power measurement being associated with an ID of the base station from which the signal was sent. The method further includes determining a correlation between the received power measurements of the first and second UEs, and based on the determined correlation, determining whether the second UE is a neighbor to the first UE.

Abstract: A method and a radio network node for scheduling wireless devices. The node assigns, to each wireless device, a D2D pair out of the D2D pairs based on spatial compatibilities for each of the D2D pairs with respect to each wireless device. The node estimates, for each wireless device and the assigned D2D pair, a first respective throughput for cellular communication and D2D communication, and estimates, for each wireless device, a second respective throughput for only cellular communication. The node schedules one or more of the wireless devices of the cellular network based on the first and second respective throughputs. Each of the wireless devices is scheduled for cellular communication together with the D2D communication of the assigned D2D pair when the first respective throughput exceeds the second respective throughput, or for only cellular communication when the first respective throughput is below the second respective throughput.

Abstract: Disclosed is a method performed by a system of network nodes in a wireless communication network, for finding neighboring user equipments, UEs, with which a first UE (121) may be able to communicate directly. The system of network nodes includes a first base station, BS, (111), and the first UE is wirelessly connected to the first BS. The method comprises receiving, from a plurality of UEs (122, 123, 124, 125) wirelessly connected to the first BS (111) and from the first UE (121), power measurements performed on signals received from neighboring BSs (112, 113, 114, 115).
