چکیده
Reconfigurable intelligent surface (RIS) technology is promising to enhance wireless communications services by providing smart radio environment. In this paper, we investigate the RIS aided cellular networks with device-to-device (D2D) users, and maximize sum of transmission rate D2D from a new perspective. addition solving typical resource allocation problems for communications, paper further optimize environment adjusting position phase shift RIS. To solve non-convex problem, propose novel decentralized double deep Q-network (D 3 QN) framework at users centralized DDQN optimization base station (BS), which are verified achieve near-optimal performance lower complexity enhanced robustness. Simulation results illustrate that proposed can higher rates compared benchmarks, meanwhile meeting quality service (QoS) requirements BS users.

Device-to-Device Aided Multicasting
We consider a device-to-device (D2D) aided multicast channel, where a transmitter wishes to convey a common message to many receivers and these receivers cooperate with each other. We propose a simple computationally efficient scheme requiring only statistical channel knowledge at transmitter. Our analysis in general topologies reveals that, when the number of receivers K grows to infinity, the...
متن کاملPerformance Analysis of Device to Device Communications Overlaying/Underlaying Cellular Network
Minimizing the outage probability and maximizing throughput are two important aspects in device to device (D2D) communications, which are greatly related to each other. In this paper, first, the exact formulas of the outage probability for D2D communications underlaying or overlaying cellular network are derived which jointly experience Additive White Gaussian Noise (AWGN) and Rayleigh multipat...
متن کاملAn Efficient Spectrum Sharing Scheme between Cellular Users and Ad-hoc Device to Device Users
To utilize spectrum resources more efficiently in a cellular network is very important but this is a very difficult task. Ad-hoc device to device communication was introduced for this purpose. By using spectrum sharing schemes we can avoid the under utilization of the spectrum. While designing such schemes interference management becomes a crucial issue. It is critical because the licensed user...
متن کاملDevice-to-Device Communication in Cellular Networks: A Survey
A constant need to increase the network capacity for meeting the growing demands of the subscribers has led to the evolution of cellular communication networks from the first generation (1G) to the fifth generation (5G). There will be billions of connected devices in the near future. Such a large number of connections are expected to be heterogeneous in nature, demanding higher data rates, less...
متن کاملScalability of Device-to-Device Communications in Cellular Networks
In current cellular networks the demand of traffic is rapidly increasing and new techniques need to be developed to accommodate future service requirements. Device-to-Device (D2D) communications is one technique that has been proposed to improve the performance of the system by allowing devices to communicate directly without routing traffic through the base station. This technique has the mean...
