Integrated Access and Backhaul in 5G with Aerial Distributed Unit using OpenAirInterface
Rakesh Mundlamuri, Omid Esrafilian, Rajeev Gangula +5
In this work, we propose an UAV-aided Integrated Access and Backhaul (IAB) system design offering 5G connectivity to ground users. UAV is integrated with a distributed unit (DU) ac…
Sensing aided Channel Estimation in Wideband Millimeter-Wave MIMO Systems
Rakesh Mundlamuri, Rajeev Gangula, Christo Kurisummoottil Thomas +2
In this work, the uplink channel estimation problem is considered for a millimeter wave (mmWave) multi-input multi-output (MIMO) system. It is well known that pilot overhead and co…
Frame based equipment channel access enhancements in NR unlicensed spectrum for the URLLC transmissions
Trung-Kien Le, Umer Salim, Florian Kaltenberger
Ultra-reliable low-latency communication (URLLC) in 5G New Radio has been originally defined only for licensed spectrum. However, due to new use cases in the Industry 4.0 scenarios…
An overview of physical layer design for Ultra-Reliable Low-Latency Communications in 3GPP Release 15 and Release 16
Trung-Kien Le, Umer Salim, Florian Kaltenberger
For the fifth generation (5G) wireless network technology, the most important design goals were improved metrics of reliability and latency, in addition to network resilience and f…
A Framework for Over-the-air Reciprocity Calibration for TDD Massive MIMO Systems
Xiwen Jiang, Alexis Decurninge, Kalyana Gopala +4
One of the biggest challenges in operating massive multiple-input multiple-output systems is the acquisition of accurate channel state information at the transmitter. To take up th…
Channel reciprocity calibration in TDD hybrid beamforming massive MIMO systems
Xiwen Jiang, Florian Kaltenberger
Hybrid analog-digital (AD) beamforming structure is a very attractive solution to build low cost massive multiple-input multiple-output (MIMO) systems. Typically these systems use…
