The use cases for Network Slicing + MEC (Mobile Edge Computing) are based on ‘end to end’ functionality and use cases. This in turn requires an ‘End to end’ approach to inter-operability, especially as the industry expects features such as cross border roaming, multi-vendor inter-operability, and consistent user experience, to be available for many use cases. Network slicing brings new capabilities to 5G devices, with the ability to provide differentiated service quality to different applications. This requires a new approach to testing the application and service layer aspects of 5G devices. There is a new type of inter-action between 3GPP protocol/modem layers and the operating system/application layers. This requires new test methods and procedures to verify both the performance of the device and application, and to verify the inter-operability and roaming/mobility scenarios. As network slicing is designed to offer the user a differentiated service, then the verification of user experience becomes a critical aspect of network slicing deployment. A test bed for evaluating end to end MEC and Network Slicing capabilities can be implemented using a network simulator such as the Anritsu MT8000A. This enables detailed verification of the device and application layer performance when using Network Slicing technology.

🔹MIMO Enhancements in 5G-Advanced (Release 19) 🔹MIMO technology will enter phase 5 evolution in 3GPP Release 19, indicating continuous enhancements over 5G releases. 🔹These enhancements aim to improve the balance between reporting overhead and latency/accuracy in beam management and support larger antenna arrays. 🔹3GPP will specify UE-initiated beam reporting enhancements, allowing the UE to trigger beam reporting instead of waiting for the gNB to trigger. 🔹The number of ports for channel state information (CSI) reporting will be increased from 32 to 128 to better support larger antenna arrays. 🔹Coherent joint transmission (CJT) will be introduced in scenarios with non-ideal synchronization and backhaul, such as inter-site CJT. This will involve UE measurement and reporting of inter transmit-receive point (TRP) time misalignment and frequency/phase offset. 🔹Non-coherent uplink codebook will be enhanced to facilitate codebook-based transmissions with three transmit antennas. 🔹Support heterogeneous networks, where a UE may receive transmission from a macro gNB in the downlink but transmit to one or more micro TRPs in the uplink to increase uplink throughput. 📒 Xingqin Lin, The Bridge Toward 6G: 5G-Advanced Evolution in 3GPP Release 19 #5G #mimo

🌐 #MassiveMIMO (Multiple Input, Multiple Output) is a key #5G technology used in most mid-band TDD deployments to achieve better coverage, higher user bitrates and increased network capacity. ⁉️ But did you know that the innovative dual-polarized beamforming technique developed at Ericsson offers the important advantage of creating broad radiation patterns while avoiding the underutilization of power resources?

To design broad beams with excellent power utilization, Ericsson researchers developed the DPBF technique. The approach is based on the fact that modern antenna systems are naturally built to exploit a pair of orthogonal polarizations. #Ericsson #MassiveMimo #5G

Back then my time in college, when I studied and proved the theory of what so called "Smart Antenna" or "Adaptive Antenna" for my final project. The combination of antenna arrays (now in standard term we call it #MassiveMIMO), the weight of amplitude and phase inputs, with algorithm could constitute beamforming and beam steering to maximize the signal transmission towards the cellular users. That's how nowadays 5G and LTE Advance technology can benefit from it to have better coverage, achieve higher throughput and capacity. But the technique was commonly known for traffic or user specific beamforming for data channel. Now 20 years later, this new innovative DPBF (Dual-Polarized Beamforming) is used in the real telco industry to also allow us to do Cell Shaping, to form a broad-beam that is suitable for broadcast and control signaling more efficiently compared to SSB sweeping technique. And with the advanced automation and intelligent algorithm, soon we can also form the cell shape adaptively to serve dominant users, reducing interference and thus do load balancing among the cells. #MassiveMIMO #5G #DualPolarizedBeamforming #CellShaping #Ericsson

Fujitsu developed a new millimeter-wave chip for #5G that supports multibeam multiplexing. This means that a single chip can now handle up to four beams for 5G base stations, resulting in faster and more efficient communication. With this new technology, Fujitsu has demonstrated that high-speed and high-capacity communications of 10Gbps or more can be achieved with an RU that is half the size of a conventional one. Not only that, but it also reduces power consumption by 30% per RU. These advancements will be instrumental in the deployment of 5G networks and the growth of the telecommunications industry. Stay tuned for more updates from Fujitsu on the future of 5G! https://lnkd.in/gdmZu4ZQ
