“…The authors in [29] show how the D2D can be implemented in 3GPP LTEAdvanced networks in details. The advantages of the D2D communications underlaying cellular radio networks are as follows: reducing the minimum co-channel reuse distances within the same cell and thus improving spectral efficiency in terms of [b/Hz/km2] (see, e.g., [40], [41], [52]), reduction of transmit power requirements, and thus improving battery life, e.g., [2], [5]- [8], [10], [16], [27], [39], [43], providing more efficient radio resource use because D2D communications requires only half the amount of resources compared to communication through the BS (e.g., [5], [7], [10]- [13]), reducing the interference in the cellular network e.g., [2], [4], [7], [19], providing infrastructure off-loading (i.e., reduces the loading of the network) in enterprise, campus, stadium, metro, shopping malls, airports, home environments, etc. [3], [32], [33], increasing the bit rate compared to cellular link due to enhanced channel characteristics ( [5], [12]), increasing communication throughput of D2D as compared to the cellular transmission (e.g., [2], [32], [39], [40], [42]), increasing network efficiency and thus supporting more services, including today's "hot" social networking applications like facebook, youtube or myspace [26], improving network performance in shadow fading [7], [9], improving performance of delay-sensitive applications [12], [32], bringing the mobile operator some further revenue [2]…”

This is the second in a two-part series of papers on transmission order (TO) optimization in the presence of channel allocation (CA), i.e., joint optimization of the TO selection and CA problem, for interfering bidirectional wireless links. Part I of this paper thoroughly analyzes the joint optimization problem from a game theoretic perspective for a general deterministic setting. Here in Part II, we present novel distributed and centralized CA-TO algorithms, together with their performance analysis, for Device-to-Device (D2D) communications underlaying cellular networks based on the findings in Part I of this paper. Here, TO is a novel dimension for optimization. In Part II, we propose and analyze novel two distributed and one centralized joint CA-TO algorithms. Our investigations show that: i) our algorithms contain many of the existing TO algorithms and CA algorithms as its special cases and can thus be considered as a general framework for the joint CA and TO optimization. The computer simulations for TDD-based D2D communications underlaying cellular network show that the proposed distributed and centralized joint CA-TO algorithms remarkably outperform the reference algorithms.Index Terms-Device-to-device (D2D) communications underlaying TDD cellular network, transmission order optimization, channel allocation problem, GADIA.

Direct communication between two or more devices without the intervention of a base station, known as device-todevice (D2D) communication, is a promising way to improve performance of cellular networks in terms of spectral and energy efficiency. The D2D communication paradigm has been largely exploited in non-cellular technologies such as Bluetooth or Wi-Fi but it has not yet been fully incorporated into existing cellular networks. In this regard, a new proposal focusing on the integration of D2D communication into LTE-A has been recently approved by the 3GPP standardization community as discussed in this paper. In cellular networks, D2D communication introduces several critical issues, such as interference management and decisions on whether devices should communicate directly or not. In this survey, we provide a thorough overview of the state of the art focusing on D2D communication, especially within 3GPP LTE/LTE-A. First, we provide in-depth classification of papers looking at D2D from several perspectives. Then, papers addressing all major problems and areas related to D2D are presented and approaches proposed in the papers are compared according to selected criteria. On the basis of the surveyed papers, we highlight areas not satisfactorily addressed so far and outline major challenges for future work regarding efficient integration of D2D in cellular networks.Index Terms-D2D communication, D2D mode selection, interference management, D2D energy efficiency, advanced topology for D2D1553-877X (c) Fig. 2.

The study introduces an exchange of messages to support the D2D functionality within the SAE and contemplates the possible limits of the D2D concerning interference issues both in the downlink (DL) and the uplink (UL) transmission directions. The paper also presents feasibility analysis evaluating performance of network with enabled D2D communication. Functional prospects of the D2D communication and its implementation into LTE-A system are tackled in [29]. The paper describes new features necessary to be added into the SAE architecture in order to support the D2D communication: radio identification and bearer setup, means to exchange the information over a D2D connection and interference management, link adaptation, timing, and mobility issues. Design aspects of network assisted D2D communication is addressed in [30]. The paper firstly provides a brief overview on technical challenges posed by enabling of D2D concept in cellular networks and provides the solutions for individual challenges.An option of architectural modification in LTE-A networks for D2D is also proposed in [31].

Device-to-Device(D2D) communications underlaying cellular networks is as a promising concept which has several advantages over the traditional cellular networks. In TDD system, the frame structure defines the order of uplink and downlink transmission slots. Typically a TDD system is synchronized and the same transmissionorder (TO) is used in all cells. In a direct D2D link, we have the freedom of selecting the TO of the devices freely. To our best knowledge, no paper has explicitly examined the TO optimization problem in D2D communications underlaying cellular network so far. In this paper, we focus exactly on this problem: Once the proper co-channel D2D pairs are determined in the network, how to minimize the network interference by optimally determining the TOs in all D2D links (together with co-channel cellular links) in the network, which is an NP-complete problem. In this paper, we formulate the TO optimization problem from a graph theoretic point of view: i) We show that TO optimization problem is equal to a constraint balanced min-cut graph partitioning problem of our defined augmented graph, ii) we propose and analyze a distributed and a centralized efficient asynchronous clustering algorithm for solving the TO optimization problem, equivalently, for the min-cut of our proposed augmented graph. Computer simulations for TDD-based D2D underlaying cellular network show that the proposed distributed and centralized algorithms, called ABCAMiC and CABCAMiC, respectively, i) remarkably outperform the reference case where all TOs are fixed, and, ii) converge within relatively small number of steps and generally converge in only a few epochs even for large number of cellular and D2D users, and, iii) the expected Manuscript performance of the (partly/fully) distributed ABCAMiC is almost equal to that of the centralized solution CABCAMiC, which generally gives near-global optimal solution to the TO optimization problem.Index Terms-Device-to-Device (D2D) communications underlaying TDD cellular network, transmission order optimization, graph representation of wireless systems, balanced min-cut graph partitioning, clustering. involvement and thus enhancing the BS resource utilization, (and by low transmit power because the MSs are relatively close to each other) or (b) The local MSs still communicate via the BS using the BS uplink (UL) and downlink (DL) resources unnecessarily (and by relatively high transmit powers if the MSs are relatively far from the BS).The answer is clear: Option (a). It's evidently resource inefficient (in terms of transmit power and bandwidth) for two proximate devices to communicate via a relatively far entity (BS) when there is a direct local path between the devices. The idea of re-using the radio resources (same frequency and time) in the spatial domain (due to the propagation loss or due to the fact that some parts of the network are shielded from other areas by natural obstructions etc) is presented in [63], and is not an innovation as pointed out by e.g. [66].
