Joint Relay Selection and Beam Management Based on Deep Reinforcement Learning for Millimeter Wave Vehicular Communication
IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY, 72(10), 13067–13080.
author keywords: mmWave MIMO; 3GPP NR V2X; relay selection; deep reinforcement learning
TL;DR:
A joint relay selection and beam management policy based on deep reinforcement learning (DRL) using the Markov property of beam indices and beam measurements is proposed, which learns time-varying thresholds that adapt to the dynamic channel conditions and traffic patterns.

Physical Layer Security at a Point-to-Point MIMO System With 1-Bit DACs and ADCs
IEEE WIRELESS COMMUNICATIONS LETTERS, 12(8), 1439–1443.
author keywords: Quantization (signal); MIMO communication; Covariance matrices; Resource management; Transmitters; Signal to noise ratio; Security; Multiple-input multiple-output communication; 1-bit digital-to-analog and analog-to-digital converters; discrete and Gaussian signaling; channel state information
TL;DR:
This letter evaluates the secrecy rate for the extreme case of 1-bit single-user multiple-input multiple-output systems following two signaling approaches and proposes an algorithm that provides near-optimal results for low signal-to-noise ratios (SNRs).

Nonuniform true time delay precoding in wideband MISO systems
2022 56TH ASILOMAR CONFERENCE ON SIGNALS, SYSTEMS, AND COMPUTERS, pp. 1233–1237.
author keywords: true time delay beamforming; wideband; multi-path; sparse eigenvalue problem; minorization-maximization
TL;DR:
This work reformulates the TTD constraint by including a sparsity regularizer penalty term in the objective and proposes a procedure to compute the delays using the precoder response obtained after solving a sparse eigenvalue problem for maximizing the total energy.

Position-Based Adaptive Power Back-Off for User Electromagnetic Exposure Management in Millimeter Wave Systems
IEEE WIRELESS COMMUNICATIONS LETTERS, 11(1), 86–90.
author keywords: Discrete Fourier transforms; Transmitters; Array signal processing; Wireless communication; Millimeter wave measurements; Millimeter wave devices; Density measurement; Millimeter wave communication; electromagnetic exposure; power density (PD); adaptive power back-off; DFT codebook
TL;DR:
This letter proposes the use of a signal-level power density model to adaptively reduce the transmit power of a millimeter wave system as the position of the device changes, and develops a method for efficiently calculating power back-off factors for beams in a discrete Fourier Transform codebook.
