Enhanced Resource Allocation in D2D Communications With NOMA and Unlicensed Spectrum

IEEE Systems Journal, 2022
Device-to-device (D2D) communications with non- orthogonal multiple access (NOMA) have been proved in enhancing the network capacity and reducing the burden of the traditional cellular network.

Ultra-Dense Networks: Integration with Device to Device (D2D) Communication

Wireless Personal Communications, 2019
The current network architecture scene can be a challenge due to the increasing number of user equipment and its diversity. Furthermore, the demand for greater data rates and lower latency by the users are increasing. Deployment of the ultra dense networks (UDN) described is to support future wireless network and meet user demands in future wireless ...

Energy-Efficient Transmit Probability-Power Control for Covert D2D Communications With Age of Information Constraints

IEEE Transactions on Vehicular Technology, 2022
Covert device-to-device (D2D) communication is recently proposed to help D2D pairs hide the existence of transmission from being detected by a warden. However, most of the existing works only focus on guaranteeing the communication covertness, while they

Cluster-Based Multicast Transmission for Device-to-Device (D2D) Communication

2013 IEEE 78th Vehicular Technology Conference (VTC Fall), 2013
The development of the storage capacity and electricity of handheld devices makes it possible to share multimedia data (e.g. video) through Device-to-Device (D2D) communication. In this paper, we present a cluster-based multicast transmission method for D2D communication with the target of decreasing the data distribution time.

Device-to-device (D2D) communication in MU-MIMO cellular networks

2012 IEEE Global Communications Conference (GLOBECOM), 2012
In this paper, we address a resource allocation problem, where a pair of device-to-device terminals are integrated into a time division duplex (TDD) cellular network. By introducing an incremental relay transmission scheme for the D2D communication, the D2D transmitter, traditionally believed to be the source of interference, are coordinated with other

Cooperative Uplink NOMA in D2D Communications

IEEE Communications Letters, 2022
In this work, we propose and investigate a novel hybrid cellular and bidirectional device-to-device (D2D) transmission scheme that exploits cooperative non-orthogonal multiple access (termed as BD2D-CNOMA). In BD2D-CNOMA, two far users can transmit their

A Joint Reinforcement-Learning Enabled Caching and Cross-Layer Network Code in F-RAN With D2D Communications

IEEE Transactions on Communications, 2022
In this paper, we leverage reinforcement learning (RL) and cross-layer network coding (CLNC) for efficiently pre-fetching requested contents to the local caches and delivering these contents to requesting users in a downlink fog-radio access network (F ...

Resource Allocation Scheme for Guarantee of QoS in D2D Communications Using Deep Neural Network

IEEE Communications Letters, 2021
In this letter, we propose a hybrid resource allocation scheme for multi-channel underlay device-to-device (D2D) communications. In our proposed scheme, the transmit power of D2D user equipment (DUE) allocated to each channel is controlled in order to ...
