Abstract

Methods and apparatus for resource allocation in a D2D network (100) are disclosed for reducing resource collisions among wireless devices (200) engaged in device-to-device (D2D) communications. In D2D communications, each wireless device (200) selects a radio resource for signal transmissions and retains the selected resource until a reselection becomes necessary. During the transmission, the wireless device (200) detects a triggering condition for resource reselection. Responsive to the triggering condition, the wireless device (200) performs resource reselection according to a reselection rule that is designed to reduce resource collisions among wireless devices (200).
