STAATSKOERANT, 8 NOVEMBER 2019 No. 42829 121 of beamforming and Coordinated Multi-Points (CoMP), called ‘Co-ordinated beamforming’ (CBF), can further enhance network performance because interference is mitigated between inter-eNodeBs. Future system requirements for IMT / LTE & IMT2020 networks 25 According to the 3GPP, in LTE-Advanced, the focus is on higher capacity. The motivation for further developing LTE towards LTE-Advanced is to provide higher bit-rates in a cost-efficient manner and, fulfil the requirements set by the ITU for IMT Advanced as shown below: ? Increased peak data rate, downlink 3 Gbps, uplink 1.5 Gbps; ? Higher spectral efficiency, from a maximum of 16 bps/Hz in Release 8 (R8) to 30 bps/Hz in Release 10 (R10); ? Increased number of simultaneously-active subscribers; ? Improved performance at cell edges, e.g. for downlink 2×2 MIMO > 2.40 bps/Hz/cell; and ? Enabled Carrier Aggregation (CA), enhanced use of multi-antenna techniques and support for Relay Nodes (RN). As LTE-Advanced continues to evolve, new CA configurations are added, and new features are introduced in upcoming releases of the 3GPP specifications, such as Coordinated Multi Point (CoMP) introduced in Release 11 (R11). The main reason for introducing CoMP is to improve network performance at cell edges. IMT2020 standards are yet to be finalised in 2020. Most IMT-2020 systems are in development stage leading towards pre-commercial phase. It is expected that IMT2020 peak data rate measured in Giga bits per second (Gbit/s) will be 20 times that of IMT-Advance in accordance with Recommendation M.2083. However, they will be significantly ahead of what’s currently available with 4G. A minimum expectation for commercial IMT2020 services is for them to be tens of times faster than 4G, which would make even current broadband speeds look sluggish in comparison. The exact speeds are yet to be finalised, early tests are already achieving remarkable results and these give us a good idea of what we can expect when IMT2020 finally launches: (a) DOWNLOAD SPEEDS The Next Generation Mobile Networks alliance states that for something to be considered IMT2020 it must offer data rates of several tens of megabits per second to tens of thousands of users 25 https://5g-news.com/index.php/2018/06/11/34/ Page 57 of 205
