Device-to-device (D2D) communications allows user equipment (UE) that are in close
proximity to communicate with each other directly without using a base station. Relay …

The complexity of the mode selection and resource allocation (MS&RA) problem has
hampered the commercialization progress of Device-to-Device (D2D) communication in 5G …

Abstract Device-to-device (D2D) communication improves spectrum efficiency (SE) and
increases system capacity. Heterogeneous networks comprise macrocell and several small …

In order to solve the problem of spectrum resource shortage and energy consumption, we
put forward a new model that combines with D2D communication and energy harvesting …

Device-to-device (D2D) communication underlaying cellular networks is seen as a

Abstract Device-to-device (D2D) communication is a promising technology in 5G new radio
(NR) interface to improve the system performance in terms of high data rate, low latency …

In this paper, we investigate a cooperative D2D communication in cognitive radio (CR)
networks, which is composed of two secondary links, one primary link, and a relay network …

The proposed work analyzes the performance of dual‐hop relaying systems by means of the
differential amplify‐and‐forward relaying method. The post‐detection selection combining …

In this work, a dual-hop relaying system using the differential amplify-and-forward relaying
scheme along with post-detection selection combining techniques is proposed. This …
