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.

Modeling and Performance Analysis of Full-Duplex Communications in Cache-Enabled D2D Networks

Cache-enabled Device-to-Device (D2D) communication is widely recognized as one of the key components of the emerging fifth generation (5G) cellular network architecture. However, conventional half-duplex (HD) transmission may not be sufficient to provide fast enough content delivery over D2D links and to meet strict latency targets of emerging D2D applications. In-band full-duplex (FD), with it...
