چکیده
Full-duplex (FD) transmissions have emerged as a spectrally efficient technology with the evolution of enhanced self-interference (SI) suppression techniques. However, FD transmission mode (TM) may not consistently outperform half-duplex (HD) TM due to residual SI. In contrast, an adaptive FD/HD scheme utilizes advantages both and HD TM. This paper proposes for cooperative device-to-device (C-D2D) communications system wherein cellular uplink data is relayed through D2D transmitter (DT). Additionally, joint DT selection algorithm introduced identify best relay favorable multiuser C-D2D system. Further, probabilistic mathematical framework developed evaluate proposed scheme. The analytical expressions outage probability each (FD/HD) been derived. Results show that performs better than when maximum two users mapped user. trade-off between observed large number users. Specifically, constraint low, TM, whereas outperforms high constraint.
