Proximal Policy Optimization for RIS-Assisted Full Duplex 6G-V2X Communications

IEEE Transactions on Intelligent Vehicles
In this work, we consider a novel reconfigurable intelligent surface (RIS)-assisted full-duplex (FD) sixth generation (6G)-vehicle-to-everything (V2X) communication network having a FD base station (BS) simultaneously communicating with an uplink (UL ...

X-Duplex: Adapting of Full-Duplex and Half-Duplex

2015 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2015
A novel hybrid model selection method between Half-Duplex (HD) and Full-Duplex (FD), is proposed in this paper. The aim of X-Duplex is to maximize the instantaneous system capacity. The system can be configured as either HD or FD mode, by adaptively configuring the antenna as either transmit or receive antenna.

A Full-duplex Speech Dialogue Scheme Based On Large Language Models

Neural Information Processing Systems
We present a generative dialogue system capable of operating in a full-duplex manner, allowing for seamless interaction. It is based on a large language model (LLM) carefully aligned to be aware of a perception module, a motor function module, and the ...

Full-Duplex WiFi

2016
WiFi technologies have received a rapid proliferation over the past decade [1]. In particular, for conventional HD WiFi networks, the CSMA/CA protocol is adopted in MAC layer; and carrier sensing is performed in the PHY layer to detect the channel ...

A Colinearly Polarized Full-Duplex Antenna With Extremely High Tx–Rx Isolation

IEEE Antennas and Wireless Propagation Letters, 2022
In this letter, we present a colinearly polarized in-band full-duplex (FD) microstrip antenna system with passive self-interference cancelation achieved from extremely high interport isolation.

Subband Full-Duplex Large-Scale Deployed Network Designs and Tradeoffs

Proceedings of the IEEE
Time-division duplex (TDD) and frequency-division duplex (FDD) are mainly used in commercial new radio (NR) deployments, where the time- or frequency-domain resources are split between downlink (DL) and uplink (UL).

Full Duplex Cooperative Rate Splitting Multiple Access for a MISO Broadcast Channel With Two Users

IEEE Communications Letters, 2022
In this letter, we investigate the performance of a full-duplex (FD) cooperative rate splitting multiple access (C-RSMA) scheme in a downlink multiple-input single-output (MISO) system consisting of one base station (BS) that serves two users ...

Full-Duplex Cellular Networks

IEEE Communications Magazine, 2017
Full-duplex (FD) communications with simultaneous transmission and reception on the same carrier have long been deemed a promising way to boost spectrum efficiency, but hindered by the techniques for self-interference cancellation (SIC). Recent breakthroughs in analog and digital signal processing yield the feasibility of over 100 dB SIC capability ...
