Extending 5G TDD Coverage With XDD: Cross Division Duplex
IEEE Access, 2021 An advanced duplex scheme called cross-division duplex (XDD) is proposed to enhance uplink (UL) coverage in time division duplex (TDD) carriers by utilizing self-interference cancellation (SIC) capability at a base station.

Linear Precoders for Non-Regenerative Asymmetric Two-way Relaying in Cellular Systems [PDF]
, 2013 Two-way relaying (TWR) reduces the spectral-efficiency loss caused in conventional half-duplex relaying. TWR is possible when two nodes exchange data simultaneously through a relay.

Ergodic Capacity and Outage Performance Analysis of Uplink Full-Duplex Cooperative NOMA System
IEEE Access, 2020 We propose an uplink full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) system, where a dedicated Full-duplex (FD) relay is used to help two uplink users transmitting information to the base station.
