Abstract: The present invention relates to a method of positioning a target node (102-4) in a side-link communication system in a wireless communication network (100). The method comprises establishing, by a first node (102-6), a communication link with a second node (102-1 to 102-3) and a third node (102-4). The first node (102-6) measures a relative Angle of Arrival (AoA) and a relative Angle of Departure (AoD) of the third node (102-4) with respect to the second node. The target node is one of the first node, the second node and the third node. The first node (102-6) estimates a position of the third node (102-4) based on at least one of the relative AoA and the relative AoD.

Abstract: In general, techniques are described for automatically and transparently providing service proxying to virtual machines using Network Interface Cards (NICs).
