Massive MIMO Evolution Towards 3GPP Release 18
Huangping Jin, Kunpeng Liu, Gilwon Lee +7
Since the introduction of fifth-generation new radio (5G-NR) in Third Generation Partnership Project (3GPP) Release 15, swift progress has been made to evolve 5G with 3GPP Release…
RF Interference in Lens-Based Massive MIMO Systems -- An Application Note
Harsh Tataria
We analyze the uplink radio frequency (RF) interference from a multiplicity of single-antenna user equipments transmitting to a cellular base station (BS) within the same time-freq…
Sum Capacity Loss Quantification With Optimal and Sub-Optimal Precoding in Heterogeneous Multiuser Channels
Harsh Tataria, Mansoor Shafi, Dino Pjanić
We analytically approximate the expected sum capacity loss between the optimal downlink precoding technique of dirty paper coding (DPC), and the sub-optimal technique of zero-forci…
Six Critical Challenges for 6G Wireless Systems
Harsh Tataria, Mansoor Shafi, Mischa Dohler +1
A large number of papers are now appearing on sixth-generation (6G) wireless systems, covering different aspects, ranging from vision, architecture, applications, and technology br…
Learning-Based UE Classification in Millimeter-Wave Cellular Systems With Mobility
Dino Pjanić, Alexandros Sopasakis, Harsh Tataria +2
Millimeter-wave cellular communication requires beamforming procedures that enable alignment of the transmitter and receiver beams as the user equipment (UE) moves. For efficient b…
