Performance Analysis and Resource Allocation for Cooperative D2D Communication in Cellular Networks with Multiple D2D Pairs

Abstract

In this paper, we investigate cooperative device-todevice (D2D) communication in an uplink cellular network where D2D users act as relays for cellular users. We derive the outage probability of a cellular user and the average achievable rate from a D2D transmitter to a D2D receiver in analytic form. We obtain optimal spectrum and power allocation to maximize the total average achievable rate under the outage probability constraint. The validity of the analysis is verified by computer simulations. The restricted battery life of user equipment (UE) is consistently one of the key worries of versatile users and a basic factor that could restrict device-to-device (D2D) correspondences. In this work, taking into account that UEs may have diverse remaining battery energy levels, we characterize the general framework endurance time as the insignificant expected battery lifetime of all communicating UEs in a cell. We at that point propose to amplify the general framework endurance time by together improving the asset designation and helpful correspondence D2D interfaces just as conventional cellular (CC) joins. Subject to the transmission rate necessity of each connection, the joint improvement issue is figured as a mixed-integer non-linear programming (MINLP) issue, which is explained by a game hypothesis, based dispersed methodology. Recreation results exhibit that our game hypothesis based RAPC approach can massively drag out the general framework endurance time as contrasted and existing methodologies.
