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…

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…
