1. A method comprising:
- determining position information for two or more user devices;
determining if the two or more user devices are in sufficiently similar positions that they are able to detect interference at the same frequency bands;
if the two or more user devices are in sufficiently similar positions, performing at least one of directing the two or more user devices to scan complementary frequency bands with one another or directing one of the two or more user devices to stop scanning;
receiving an estimation of interference level detected by the user device on a scanned frequency range of a candidate band of a primary system; and
evaluating, based on the at least one estimation of the interference level and the position of at least one of the user devices, interference level in an entire cell area.

Abstract
The invention provides methods, a network device and radio station for spectrum resource allocation in a network employing spectrum sharing among at least a primary and secondary system, including scanning, by a network device of the secondary system, a specific frequency range of a candidate band of the primary system, estimating, by the network device, interference level on the scanned candidate band of the primary system, determining position of the network device, and transmitting the estimation result to a radio station of the secondary system.

6. An apparatus comprising:
-
at least one processor; memory storing a program of instructions; wherein the memory storing the program of instructions is configured to, with the at least one processor, cause the apparatus to perform at least; determining position information for two or more user devices; determining if the two or more user devices are in sufficiently similar positions that they are able to detect interference at the same frequency bands; if the two or more user devices are in sufficiently similar positions, performing at least one of directing the two or more user devices to scan complementary frequency bands with one another or directing one of the two or more user devices to stop scanning; receiving an estimation of interference level detected by the user device on a scanned frequency range of a candidate band of a primary system; and evaluating, based on the at least one estimation of the interference level and the position of at least one of the user devices, interference level in an entire cell area. - View Dependent Claims (7, 8, 9, 10)
