US 10,477,377 B2 · Network node and method for managing radio resources dedicated to beacon signaling for D2D discovery

Abstract

A network node (110) and a method therein for managing radio, resources are disclosed. The radio resources are dedicated for beacon (121, 122) signaling, fey a first device; (131) and a second device (132), in conjunction with device-to-device, “D2D”, discovery. The first device: (131) is stationary and the second device (132) is non-stationary. The network node (110) selects (202) a first and a second set of radio resources out of the radio resources. The first arid second sets are dedicated for beacon signaling by the first device (131) and the second device (132), respectively. The first set of radio resources Is non-overlapping with the second set of radio resources. Then the network node (110) schedules (203) a specific radio resource of the first set of radio resources to the first device (131). Next, the network node (110) sends (204) information about the scheduled specific radio resource to the first device (131). The network node (110) further sends (205) information about the second set of radio resources to the second device (132). In this manner, the second device (132) restricts Us radio resources usable for beacon signaling to the second set of radio resources.
