The cluster-wise multi-user multi-input multi-output (MU-MIMO), division of the ultra-dense
network in the beyond fifth-generation (B5G) system into several small-scale MU-MIMO, is …

In multiuser communication systems, user scheduling and beamforming (US-BF) design are
two fundamental problems that are usually studied separately in the existing literature. In this …

Resource allocation is a fundamental task in cell-free (CF) massive multi-input multi-output
(MIMO) systems, which can effectively improve the network performance. In this paper, we …

In this paper, we study a multiple-input single-output (MISO) assisted multi-user downlink
network. To support low-latency communications, the transmissions to massive users are …

Cell-free (CF) massive multiple-input multiple-output (MIMO) systems are expected to
provide high spectral efficiency to all users, regardless of their locations, when equipped …

Compared with the traditional collocated multi-input multi-output system (C-MIMO),
distributed MIMO (D-MIMO) systems have the advantage of higher throughput and coverage …

The idea of utilizing multiple antennas (MIMO) has emerged as one of the significant
breakthroughs in modern wireless communications. MIMO techniques can improve the …

In this paper, we focus on the well-known drawback of per user unitary beamforming rate
control (PU 2 RC) that sum throughput severely degrades with a small number of users due …
