This paper investigates a layered power allocation (PA) non-orthogonal multiple access (NOMA) scheme for device-to-device (D2D) relaying networks, where the strategy of partial data transmission at relay nodes are adopted to improve the efficiency of resources. In addition, to satisfy different quality-of-service (QoS) requirements from multiple users,

Interference mitigation and D2D parameter estimation for distributed‐control D2D underlay systems
Transactions on Emerging Telecommunications Technologies, 2015AbstractAlthough centralised‐control schemes for device‐to‐device (D2D) underlay communications can produce satisfactory results by efficiently managing the interference between cellular and D2D transmissions, they can become prohibitively complicated and may require a large amount of feedbacks from devices, because it is important to handle the inter ...

Secure communications with D2D cooperation
2015 International Conference on Communications, Signal Processing, and their Applications (ICCSPA'15), 2015Device to Device (D2D) communications provides a promising technique for 5G wireless networks, supporting higher data rates. Security of data transmission over wireless clouds could put constraints on devices; whether to cooperate or not. Therefore, our aim is to provide analytical framework for the security at the physical layer and to define the ...

Efficient Resource Allocation and Power Control for LTE-A D2D Communication With Pure D2D Model
IEEE Transactions on Vehicular Technology, 2020To support the rising number of user equipments (UEs), LTE-A allows some UEs directly talking with each other to facilitate spectrum reuse, which is known as device-to-device (D2D) communication . Since D2D UEs (DUEs) consume resources and bring out interference, how to allocate resources and power is important. Existing studies seek to make more DUEs

Revenue Maximization in D2D Content Relaying
2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019Incentivizing the device-to-device (D2D) users can promote co-operative communication between them. In this work, we consider a scenario, where a content provider who wish to propagate his message, seeks base station's (eNB) assistance to advertise. The eNB will incentivize D2D users (DUs) to relay the message among its neighbors that have subscribed ...
