Interference mitigation is a major challenge in deploying a two-tier small cell network, where small cells are deployed underlaying a central macrocell and share the same spectrum with the macrocell. In this paper, we develop a new decentralized power control solution for interference mitigation in a two-tier small cell network, from a game theoretic perspective. We aim to maximize the number of small cell user (SU) transmissions that can be admitted in the network while satisfying the signal-to- interference-noise ratio (SINR) constraints of both transmitting SUs and the macrocell user (MU). We formulate the problem of power control for SUs as a game with common utility. The Nash equilibria of the game are investigated. We then propose a learning automata based distributed discrete power control algorithm with which the SUs can learn from their action-reward histories and adjust their transmit powers towards a NE point. Simulation results show the proposed algorithm achieves higher number of SU transmissions that can be admitted compared with existing schemes in the literature.

Due to the tremendous growth of mobile data traffic, some technologies from small cell deployment are still ongoing as nominated solutions. Without enlarged wired backhaul capacity, however, the performance of small cell techniques are inevitably degraded. The approach employing the storage capacity in order to off-load the backhaul capacity, as known as femto-caching, has been proposed to minimize the delay within downloading data [1]. In this paper, we consider more practical scenario such as distribution of users' position in whole networks and extend the previous researches in the manner of file placement strategies. Simulation results verify that our proposed scheme has better performance gains with respect to increased opportunity to obtain more various downloading data if helpers' coverages are overlapped.

In this paper, we propose a fairness-controlled multiuser scheduling and resource allocation (RA) algorithm for uplink spatial division multiple access (SDMA)/ single carrier frequency division multiple access (SC-FDMA). In fact, with the aim of improving the spectral efficiency (SE) and at the same time controlling the network fairness, a sub-optimal power projection method based on users' spatial correlation is employed, which chooses the users for each resource block (RB). We assume a single-input multiple-output (SIMO) scheme with correlation at receive antenna. By changing the maximum allowed number of simultaneously accessing users, we can choose the desired balance between SE and the fairness. Numerical analysis verifies that the proposed scheme improves the SE considerably at the target defined fairness level. We also investigate the variations in fairness for different system design parameters, i.e., RB size, number of receive antenna, etc.

Dynamic base station downlink discontinuous transmission (DTX) operations have been proposed and under discussion in the standardization body as a candidate to reduce interference in the LTE network to support rapidly increasing demand for mobile broadband services and traffic volumes [1]. In this paper, we analyze the energy efficiency improvement of the dynamic base station DTX operations from three perspectives. First, we discuss the complementary operation aspect of the dynamic base station DTX and existing LTE dormant mode. Secondly, we provide an analysis showing substantial energy efficiency benefits at all loads of dynamic base station DTX operation with near- future base station hardware components. Thirdly, we provide an analytical framework to assess the energy saving potential of the dynamic base station DTX concept for all possible future hardware improvement possibilities.

Visible light communication (VLC) has recently emerged to become a promising wireless communication technology. Vehicle lights and traffic lights have started to utilize LEDs and due to their shorter response time, they can be easily modified to become VLC transmitters. In addition, cameras embedded in smartphones can be used as VLC receivers. As a result, Vehicular VLC (V2LC) between vehicle lighting and smartphone cameras has the potential to enable a great number of applications with low cost. In this paper, a prototype V2LC system that utilizes undersampled frequency shift ON-OFF keying (UFSOOK) modulation is proposed. The system utilizes rolling shutter cameras as the receiver and takes advantages of its characteristics to improve the receiving performance. An off- the-shelf vehicle LED taillight is used as the transmitter. Information is transmitted in the continuous state (ON-OFF) changes of LEDs which are invisible to human eyes. The performance evaluation results demonstrate that the communication prototype is robust and can resist common optical interferences and noises within the image.

In this paper, we investigate channel estimation methods in carrier aggregation (CA) orthogonal frequency division multiplexing (OFDM) systems. Carrier aggregation (CA) is one of the most distinct features of 4G that allows operators to deploy a system with larger bandwidth by aggregating several smaller contiguous or non-contiguous carriers. By taking advantage of the channel correlation that presents among different carrier components (CC) accessing the same physical link, new approaches are developed and proposed from pilot-assisted, blind, and semi-blind channel estimation. Simulation results show that the proposed channel estimation methods with combining data from different bands outperform methods that perform channel estimation in individual bands.

This paper presents a design of two-way two-hop relay network using physical layer network coding (PNC) in which multiple antennas are used at all nodes. For transmission over the multiple-input multiple-output channels, the Alamouti's space-time block code (STBC) is used for transmission while linear detection is used for signal estimation at all nodes. In order to facilitate linear detection, we develop an equivalent multiuser STBC model for the proposed network and design the sum-and-difference matrix which is suitable for signal estimation. Simulation results show that the proposed network achieves diversity order 2 with polynomial complexity.

Rateless code based communications for unicast applications require the decoder to indicate successful decoding of a batch of input packets before the encoder moves to a new batch. This will cause significant overhead when the number of input packets is restricted or when considering long distance, high capacity links. This is mainly due to the fact by the time the acknowledgement packet is received at the encoder, a large number of redundant encoded packets are injected into the communication link. This study proposes a practical solution to address the issue by introducing a two- level acknowledgment scheme and by dynamically accounting for the on-the-fly packets. The solution is implemented in an end-to-end rateless-code based scenario where the experimental results confirm the feasibility of the solution and notable throughput improvement gains when using this scheme.

We address the issue of interference in co-channel heterogeneous cellular networks where low-power pico cells are overlaid on high-power macro cells. Interestingly, unlike homogeneous networks, the co-channel heterogeneous networks exhibit special interference characteristics. This stems due to the transmit power mismatch in macro and pico layers. Interference alignment is one of the techniques that has been proposed to manage the interference in homogeneous macro cellular networks. Hence it is important to analyse the impact of power mismatch on interference alignment in the heterogeneous networks. For this purpose, we assess the performance of multi user inter cell interference alignment based transmit precoding scheme with different user selection methods in a heterogeneous network scenario. The results for pico cells show that the interference alignment based transmit precoding is well supported by the alignment based user selection method. Additionally, we compare the performance of alignment based transmit precoding with the state of the art non-alignment based precodings. We find that interference alignment is more robust to the power mismatch than its non-alignment based counterparts. This suggests that interference alignment can also be exploited as interference management scheme in co-channel heterogeneous networks.

Extended Floating Car Data (xFCD) is the fundamental for many modern traffic forecast systems. In this paper, an xFCD source model with different transmission rules for making the data efficiently available at the forecast server by means of Long Term Evolution (LTE) enabled Machine-Type Communication (MTC) is proposed. Thereby, the delay requirements of the sensor data and the channel conditions of the communication link are taken into account. The results show that the new source model leads to a decreased utilization of the LTE system and therefore to a low service degradation of other human cellular users. Furthermore, the inserted delay of the data transmission is tolerable for the considered application.
