This paper studies the OkumuraHat propagation model on CDMA technology applied in AMI (Advanced Metering Infrastructure). The aim of this proposal is to get information from the intelligent meter such us: outage management system, status and ratings reading. Prepaid services are oriented to the specific characteristics of rural dwellers. Furthermore, it allows to the energy distribution companies to know the energy consumption in real time. The Okumura -Hata propagation model helps to evaluate a communication system due to its good practices and results obtained with this method using cellular technology. The use of CDMA technology in electrical measurement systems helps to reduce the costs of non-technical losses, resulting in: better quality in the electrical systems and obtaining actual data readings that improves communication between the consumer and the distributor.

“…Towards 5G networks and enabling the D2D communication capabilities of the users [18][19][20], respective RB allocation approaches can be found in [21][22][23]. In [21] the importance of RB allocation approaches in various and emerging network architectures is stressed via presenting different approaches in LTE and LTE-Advanced networks. In [22] the authors propose scheduling algorithms for the problem of RB allocation in D2D enabled networks taking into account each user's delay requirement.…”

Multicell Interference Management in Device to Device Underlay Cellular Networks

Abstract:In this paper, the problem of interference mitigation in a multicell Device to Device (D2D) underlay cellular network is addressed. In this type of network architectures, cellular users and D2D users share common Resource Blocks (RBs). Though such paradigms allow potential increase in the number of supported users, the latter comes at the cost of interference increase that in turn calls for the design of efficient interference mitigation methodologies. To treat this problem efficiently, we propose a two step approach, where the first step concerns the efficient RB allocation to the users and the second one the transmission power allocation. Specifically, the RB allocation problem is formulated as a bilateral symmetric interaction game. This assures the existence of a Nash Equilibrium (NE) point of the game, while a distributed algorithm, which converges to it, is devised. The power allocation problem is formulated as a linear programming problem per RB, and the equivalency between this problem and the total power minimization problem is shown. Finally, the operational effectiveness of the proposed approach is evaluated via numerical simulations, while its superiority against state of the art approaches existing in the recent literature is shown in terms of increased number of supported users, interference reduction and power minimization.

“…In Figure 1, the BS is subject to SI and the UEs transmitting in the UL (UE 2 and UE 4 ) cause UE-to-UE interference to co-scheduled UEs receiving in the DL, that is to UE 1 and UE 3 respectively. We assume that within a large number of served users a smaller subset is selected by an appropriate scheduler for data transmission in the UL and reception in the DL, which is supported by current implementation of Long Term Evolution (LTE) systems [26,Section III]. The number of UEs in the UL and DL are denoted by I and J, respectively, which are constrained by the total number of frequency channels in the system F , i.e., I ≤ F and J ≤ F .…”

Abstract-In cellular networks, the three-node full-duplex transmission mode has the potential to increase spectral efficiency without requiring full-duplex capability of users. Consequently, three-node full-duplex in cellular networks must deal with selfinterference and user-to-user interference, which can be managed by power control and user-frequency assignment techniques. This paper investigates the problem of maximizing the sum spectral efficiency by jointly determining the transmit powers in a distributed fashion, and assigning users to frequency channels. The problem is formulated as a mixed-integer nonlinear problem, which is shown to be non-deterministic polynomial-time hard. We investigate a close-to-optimal solution approach by dividing the joint problem into a power control problem and an assignment problem. The power control problem is solved by FastLipschitz optimization, while a greedy solution with guaranteed performance is developed for the assignment problem. Numerical results indicate that compared to the half-duplex mode, both spectral and energy efficiencies of the system are increased by the proposed algorithm. Moreover, results show that the power control and assignment solutions have important, but opposite roles in scenarios with low or high self-interference cancellation. When the self-interference cancellation is high, user-frequency assignment is more important than power control, while power control is essential at low self-interference cancellation. I. INTRODUCTIONIn order to meet the need for explosive data volumes and data rates, wireless network operators seek to enhance the spectral efficiency in lower-frequency bands [1], and to exploit higher-frequency bands such as the millimiter waves. The research and standardization communities are currently studying physical layer technologies, including massive MIMO systems, spectrum sharing in mmWave networks, new waveforms, non-orthogonal multiple access technologies, and full-duplex communications [2], [3].In-band full-duplex (FD) transceivers are expected to improve the attainable spectral efficiency of traditional wireless networks operating with half-duplex (HD) transceivers by a factor of two [3]. Due to recent advancements in mitigating the inherent self-interference (SI) by means of passive suppression, analog and/or digital cancellation, in-band FD technology is quickly approaching the phase of commercial deployments in low-power wireless networks [4].
