Background 5G is set to change the picture significantly in terms of spectrum allocation and use, and in this article, we aim to provide more clarity in terms of the many issues related to the licensing, standardisation / harmonisation, and use of spectrum as we head towards the 5G era. Spectrum is highly sought after, primarily because it allows an operator to increase capacity on the network efficiently. The additional spectrum can be added to existing base stations which reduces the number of new base stations needed. This makes spectrum highly valuable, hence regulators will charge a fee for licensed...

In the original version of LTE (3GPP R8), a UE only communicated with a single eNB, by means of a single cell. LTE-A (R10) introduced CA (Carrier  ggregation), in which a UE supports a higher data rate by communicating with multiple cells on multiple carrier frequencies. All the cells are controlled by a single eNB. There is one PCell (Primary Cell), which carries traffic and RRC signalling messages, and optionally one or more SCells (Secondary Cells), which carry traffic alone. The PCell supports both UL and DL, but the SCells can be DL-only.DC (Dual Connectivity) was introduced in 3GPP R12. When using...

Many of the benefits of 5G, such as low user plane latency, high data rate and support of high radio frequencies, can be achieved simply by transmitting data over the 5G New Radio. Furthermore, there are market pressures on network operators for an early roll-out of 5G networks in which those benefits are delivered to the user. To reflect these issues, 5G is designed to support an evolutionary roll-out in which operators can gradually introduce the capabilities of 5G into their networks, without the immediate need for wide-area 5G coverage. This is achieved using a number of different architectural options,...

Furthermore, there are market pressures on network operators for an early roll-out of 5G networks in which those benefits are delivered to the user. To reflect these issues, the 5G New Radio is designed to support an evolutionary roll-out in which it inter-operates closely with LTE. The resulting architecture is closely based on the architecture for DC in LTE.In the first phase, the mobile continues to communicate...

Webinar Recorded: 13th October 2021 The Service Based Architecture (SBA), standardised as part of 5G, represents a paradigm shift in the way the telecoms core network is planned, deployed, and operated. Using virtualisation principles, the SBA provides a more flexible, efficient, and capable set of features – provided by the different Network Functions in the form of NF “Services”. SBA techniques can also be applied to 4G, and if adopted early, would enable a smooth transition to the 5G Core.This talk examines the principles of the SBA, before looking in more detail at the architecture, network functions, protocols, and operation. We also...
