Joint Beamforming and Compressed Sensing for Uplink Grant-Free Access
Guoqing Xia, Pei Xiao, Bohan Li +2
Compressed sensing (CS)-based techniques have been widely applied in the grant-free non-orthogonal multiple access (NOMA) to a single-antenna base station (BS). In this paper, we c…
MDD-Enabled Two-Tier Terahertz Fronthaul in Indoor Industrial Cell-Free Massive MIMO
Bohan Li, Diego Dupleich, Guoqing Xia +4
To make indoor industrial cell-free massive multiple-input multiple-output (CF-mMIMO) networks free from wired fronthaul, this paper studies a multicarrier-division duplex (MDD)-en…
Spectral-Efficiency of Cell-Free Massive MIMO with Multicarrier-Division Duplex
Bohan Li, Lie-Liang Yang, Robert G. Maunder +2
A multicarrier-division duplex (MDD)-based cell-free (CF) scheme, namely MDD-CF, is proposed, which enables downlink (DL) data and uplink (UL) data or pilots to be concurrently tra…
Multicarrier-Division Duplex for Solving the Channel Aging Problem in Massive MIMO Systems
Bohan Li, Lie-Liang Yang, Robert G Maunder +2
The separation of training and data transmission as well as the frequent uplink/downlink (UL/DL) switching make time-division duplex (TDD)-based massive multiple-input multiple-out…
Heterogeneous graph neural network for power allocation in multicarrier-division duplex cell-free massive MIMO systems
Bohan Li, Lie-Liang Yang, Robert G Maunder +2
In-band full duplex cell-free (CF) systems suffer from severe self-interference and cross-link interference, especially when CF systems are operated in distributed way. To this end…
