LTE is based on the GSM/EDGE (“Global System for Mobile Communications”/“Enhanced Data rates for GSM Evolution” also called EGPRS) of the second generation (“2G”) and UMTS/HSPA (“Universal Mobile Telecommunications System”/“High Speed Packet Access”) of the third generation (“3G”) network technologies.

LTE is standardized under the control of 3GPP (“3rd Generation Partnership Project”) and there exists a successor LTE-A (LTE Advanced) allowing higher data rates than the basic LTE and which is also standardized under the control of 3GPP.

For the future, 3GPP plans to further develop LTE-A such that it will be able to fulfill the technical requirements of 5G.

As the 5G system will be based on LTE or LTE-A, respectively, it is assumed that specific requirements of the 5G technologies will, basically, be dealt with by features and methods which are already defined in the LTE and LTE-A standard documentation. 5G technologies will allow a concept of a so called “virtual cell” or “l(fā)ocal cell” or the like, which may also be based on NR. In this concept a cell is served by a user equipment (UE), e.g. a mobile phone, a computer, tablet, tablet personal computer or the like including a mobile communication interface, or any other device which is able to perform a mobile telecommunication via, for example, LTE(-A), such as a hot spot device with a mobile communication interface. In short, the UE works dynamically as an intermediate node for establishing an indirect network connection between other UEs in the vicinity of the virtual cell or local cell and the network, and/or as an intermediate node between UEs. A function of the intermediate node on the UE may also be carried out by “virtualization”. A virtual cell or local cell may communicate with UEs in unlicensed, shared licensed or licensed bands, and it backhauls to network preferably in licensed bands.
