In this paper, the application of #integrated #access and #backhaul (#IAB) technique in #millimeter-#wave (#mmWave) #cell-#free (#CF) massive #MIMO systems is investigated. The access and backhaul links share a frequency spectrum in the mmWave bands, and in both, #hybrid #beamforming techniques are adopted for signal transmission. The bandwidth allocation (division) parameter between the two link types as well as the beamforming matrices are optimized to maximize the end-to-end data rate. This leads to a non-convex optimization problem for which an efficient solution method is proposed. ---- Ali Hosseinalipour jazi, S.

Optical wireless communication – or #LiFi – is the future of network technology. But what exactly is LiFi? LiFi transmits data through light waves instead of radio waves that are used in conventional #WiFi. This opens up a whole new spectrum of previously untapped communication frequency and complements radio, where higher user density requires more capacity. Optical wireless communication is tap-proof, immune to electromagnetic interference and easily protected since it does not penetrate walls. Nowadays, a LiFi cell has 1-10 m diameter and delivers data rates from 100 Mbit/s to 1 Gbit/s. LiFi is based on commercially available high-performance LEDs and has been tested in vehicle-to-vehicle communication, industry environments and even a school.

Researchers achieve record-breaking data transmission speed with expanded fibre bandwidth A new achievement in data transmission has been announced by researchers from Japan and the United Kingdom. By broadening the communication bandwidth of commercial-grade optical fibre, the team has set a new record for data transmission speed, achieving rates four times faster than existing commercial systems. This impressive feat marks a 33 percent increase over the previous record. Led by the Photonic Network Laboratory of the National Institute of Information and Communications Technology (NICT), the team demonstrated an aggregate optical transmission bandwidth of 37.6 THz, achieving a data rate of 402 terabits per second. This was accomplished using standard commercially available optical fibre. This achievement paves the way for the future of "Beyond #5G" information services, enabling higher data-rate transmission and extending the lifespan of existing #FibreNetworks. As internet and data service demands continue to surge, these innovations are crucial for the evolution of global communication infrastructure. https://lnkd.in/egedwVAB

#5gtechnology & #How it is benefit in market ? #5g is based on OFDM (Orthogonal frequency-division multiplexing), a method of modulating a digital signal across several different channels to reduce interference. 5G uses 5G NR air interface alongside OFDM principles. 5G also uses wider bandwidth technologies such as sub-6 GHz and mmWave. 5G technology uses cell sites that transmit data through radio waves. Cell sites connect to networks with wireless technology or wired connection. 5G technology works by modifying how data is encoded, significantly increasing the number of usable airwaves for carriers #5g benefits in the market The key functional drivers of 5G will unlock a broad range of opportunities, including the optimization of service delivery, decision-making, and end-user experience. This will result in $13.2 trillion in global economic value by 2035, generating 22.3 million jobs in the 5G global value chain alone.

This letter provides a practical framework to resolve whether #code-#domain #NOMA (#CD-#NOMA) is beneficial when integrated with massive MIMO systems. In order to realize this integration, first, the authors develop a novel code-beamspace wideband signal model for uplink CD-NOMA in mmWave hybrid #massive #MIMO systems employing #single-#carrier (#SC) transmission. Then, they apply a state-of-the-art #SC #frequency #domain #equalization (#SC-#FDE) based iterative receiver where the number of #radio #frequency (RF) chains is limited. ---- Gokhan Muzaffer Guvensen More details can be found at this link: https://lnkd.in/gve2DiRZ

🔹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
