IEEE Transactions on Wireless Communications

Year: 2025 | Volume: 24, Issue: 3 | Journal Article |

This paper considers multiuser millimeter wave (mmWave) MIMO communication systems where both the base station (BS) and the user equipments (UEs) use analog beamforming (BF). We propose a beam acquisition approach to find the best directions for the narrow beams, required to achieve BS-UE links above a minimum signal-to-noise ratio (SNR) threshold. The multiple UEs first select their beams simulta...Show More

Resource Scheduling in mm-Wave Communications

Kimia Hamouleh Kheirollah Pour;Iain B. Collings;Stephen V. Hanly

2024 17th International Conference on Signal Processing and Communication System (ICSPCS)

Year: 2024 | Conference Paper |

Millimeter wave (mm-Wave) frequencies provide high data rates while encountering issues like high penetration losses and obstruction. To overcome these challenges, large antenna arrays and analog beamforming with phase shifters are utilized. This can lead to overlapping coverage areas and interference between beams, making resource scheduling (user, beam, time, and data rate) a complex and critica...Show More

Low Earth Orbit (LEO) satellites are increasingly being used to provide connectivity for wide area Internet of Things (IoT) sensing applications. Distributed IoT terminals are not able to coordinate their uplink transmissions to the nano-satellites, and so operate in a grant-free mode. Quality-of-Service (QoS) depends on the transmission attempt success statistics, which are time-varying. This pap...Show More
