CONFIGURATION OF NETWORK NODES

摘要

There is provided configuration of a secondary network node in a carrier aggregation enabled communications network The secondary network node supports radio transmission using a cellular radio access technology (RAT) for deployment as a network node serving a secondary serving cell associated with a primary serving cell in a carrier aggregation enabled communications network using the cellular RAT and a non-cellular RAT for deployment as a network node serving a non-cellular RAT hotspot using the non-cellular RAT. After receiving an indication from a cellular primary network node associated with the primary serving cell the secondary network node starts scanning an unlicensed frequency band for deployment of the network node. The secondary network node determines at least one frequency interval of the at least one unlicensed frequency band substantially free from transmitting interferers. Based on information received from the cellular primary network node the secondary network node deploys the network node using the cellular RAT or the non-cellular RAT by configuring the secondary network node for transmission in one of the at least one frequency interval according to the configuration information.
