In this paper, we propose a novel energy harvesting (EH)-enabled time-division multiple access symbiotic radio (TDMA-SR) system to support massive ambient Internet of Things (IoT) connections. To address the challenge of heterogeneous link conditions in large-scale deployments, we introduce a channelaware frame structu...

Existing integrated sensing and communications (ISAC) systems are generally confined to sensing physical states of targets (e.g., positions and velocities), yet remain incapable of acquiring target identities. In light of this, we incorporate a backscatter communications (BackCom)-based target identification system int...

Movable antennas (MAs) provide additional spatial degrees of freedom (DoFs) for interference suppression by adaptively reconfiguring antenna positions in near-field environment. However, existing MA-based designs fail to suppress mainlobe and grating-lobe interference simultaneously. To address this issue, we propose a...
