Abstract: This document discloses a solution for performing spectrum allocations. According to an aspect, there is provided a method comprising: performing, by a spectrum sharing adaptation system, allocation and transmission authorization of a shared spectrum resource to a network element of a communication network, wherein the shared spectrum resource is on frequencies not exclusively licensed to the communication network, and wherein the spectrum sharing adaptation system allocates the shared spectrum resource to the network element by using a first spectrum sharing protocol; acquiring, by the spectrum sharing adaptation system, allocation and transmission authorization of the shared spectrum resource from a spectrum resource manager managing utilization of spectrum resources, wherein the spectrum sharing adaptation system acquires the allocation of the shared spectrum resource by using a second spectrum sharing protocol different from the first spectrum sharing protocol; and performing, by the spectrum sharing adaptation system, adaptation between the first spectrum sharing protocol and the second spectrum sharing protocol.
