Low power node which preferably allocates PCell on carrier in frequency band shared with macro node

摘要

A low power network node (LPN) and a method performed thereby for providing a primary serving cell to a wireless device associated with the low power network node. The wireless communication network also comprises a neighboring network node, wherein the low power network node and the neighboring network node are configured with a first set of frequency bands B′ and the low power network node is configured with a second set of frequency bands B″. Since the neighboring network node does not use the second set of frequency bands B″, the neighboring network node may not cause interference on carriers of the second set of frequency bands B″.
