Mobility robustness optimization (MRO) is one of the Self Organizing Network (SON) features that automatically adjusts network mobility configurations by detecting problems and correcting handover (HO) parameters. The existing MRO operation is based on stationary network deployment assumption where handover error statistics are continuously monitored between cell-pair borders as long as the cells shape and neighbor relationships are maintained. In the dynamic deployment case, where cell deployment layout is changing by following the nature of the traffic distribution, existing neighbor relationships might not be maintained and new neighbors could appear in the network. In such cases, MRO instances and counters used before deployment change might not be valid any longer for the new network layout. In this paper work, we have studied the impact of deployment and network layout change introduced by Vertical Sectorization (VS), a typical Active Antenna Systems (AAS) feature, on the performance of MRO. A crucial aspect here is the treatment of MRO statistics while introducing a change in the network deployment layout. The study gives information if there is a need to enhance the existing MRO concepts by introducing inter-node coordination during execution of a deployment change in the network.

The Digital Agenda for Europe (DAE) sets forth ambitious requirements for broadband communications, in which Satellite Communications (SatCom) play a major role. In this context, spectrum sharing techniques offer unprecedented opportunities to increase capacity and reduce costs in order to allow SatCom to meet the DAE objectives. The EU FP7 Project CoRaSat is assessing Cognitive Radio (CR) techniques for Ka-band SatCom scenarios, showing that coexistence between Fixed Satellite Service (FSS) and Broadcasting Satellite System (BSS)/Fixed Service (FS) links would introduce significant benefits in non-exclusive frequency bands. In this paper, spectrum awareness and exploitation techniques are analyzed. Simulation results show that significant improvements can be obtained in both spectrum utilization (up to 2.4 GHz of additional spectrum) and available throughput (up to 600% increase).

Primary User Emulation (PUE) attack is a serious security problem in cognitive radio (CR) network. A PUE attacker emulates a primary signal during sensing duration in order the CR users not to use the spectrum. The PUE attacker is either selfish if it would like to take benefit of the spectrum, or malicious if it would like to do a Deny of Service of the CR network. In this paper, we only consider malicious PUE. We propose to perform sometimes an additional sensing step, called extra-sensing, in order to have a new opportunity to sense the channel and so to use it. Obviously the malicious PUE may still perform an attack during this extra-sensing. Therefore, our problem can be formulated as a zero-sum game to modeling and analyzing the strategies for two players. The equilibrium is expressed in closed-form. The results show that the benefit ratio and the probability of channel's availability strongly influence the equilibrium. Numerical results confirm our claims.

We consider the problem of allocating power among the nodes of a two-way amplify-and-forward OFDM-based relay network employing physical layer network coding. Because of the large peak-to-average power ratios that occur at the relay of such systems, we deem it important to understand the negative effects that nonlinear transmissions might have at the relay. Thus, we assume that the relay is subject to its own independent transmit power constraint, beyond which nonlinear distortion is introduced. We consider two power allocation problems: 1) the transmit power budget of the communicating nodes is independent of the relay's transmit power, 2) the relay's transmit power is included within the total power budget of the network. For the former, a closed form solution is obtained. For the latter, the problem is shown to be non-convex in its standard form. By applying a substitution, we show that it can be converted into a convex problem. Numerical results are provided to demonstrate the efficacy of our methods. Finally, a discussion is included to give further insight into how our power allocation scheme behaves as a function of the network's asymmetry.

For full-data exchange multi-way relay channels, a novel efficient multi-way relay network coding scheme is proposed. It is based on multi-stage two-way network coding, which is low-complexity and high reliable. For the channel without noise, the throughput per node per channel is increased by 50 % compared to plain routing, and even by 12.5% compared to the binary-signaling network coding scheme. Besides, due to the simple nature of 3-pulse amplitude modulation (3-PAM), it has much lower complexity and much higher reliability compared to the binary-signaling network coding scheme. Both theoretical analysis and computer simulations prove such throughput gain. On the additive white Gaussian noise (AWGN) channel, low density parity check (LDPC) codes are utilized in this scheme to improve the reliability. The simulation results show that the signal-to-noise ratio (SNR) gains to reference scheme increase as the number of the source nodes increases, and the SNR gains of the LDPC-coding scheme are even bigger than the uncoding scheme.

Assuming statistical Channel State Information (CSI) available at the relay, the performance of a dual-hop MIMO relay network is studied in this paper. The cumulative density function (cdf) of received SNR at destination is studied and closed-form expressions are derived for the asymptotic cases of fully-correlated and non-correlated scenarios; moreover, the statistical characteristics of the SNR is further studied and an approximate cdf of the SNR is derived for arbitrary correlation. Then, a simple power allocation algorithm is proposed which is called “proportional power allocation”. The algorithm is explained in detail for the case of two antennas and three antennas at the relay. The simulation show excellent agreement between the proposed algorithm and optimal solution that is obtained by exhaustive search.

In this paper, we focus on subcarrier and power allocation for an orthogonal frequency division multiple access (OFDMA) full-duplex (FD) system. A three-step algorithm is proposed to maximize the sum-rate of the system subject to individual rate constraints at the uplink and downlink users, and transmit power constraints at the base station (BS) and uplink users. The steps are: 1) Subcarrier allocation that considers user target rate requirements, 2) residual subcarrier allocation that further increases the sum rate, and 3) power allocation based on iterative water-filling (IWF). Simulation results reveal that the proposed FD scheduling improves the sum-rate over the traditional half-duplex (HD) and round-robin (RR) scheduling significantly under the self-interference cancellation levels that has been recently achieved.

Carrier Aggregation is an important feature in Long Term Evolution Advanced (LTE-A). It allows operators to provide larger operational bandwidths without the need of having a contiguous, large piece of spectrum. However, an increased bandwidth also needs a larger channel sounding to obtain channel state information (CSI), required for frequency domain scheduling and link adaptation. This constitutes a serious challenge for the uplink since wideband sounding reference signals cannot be transmitted by cell edge (power limited) users and hopped sounding requires a long time to sweep the entire transmission band, thus leading to outdated and less reliable CSI. Also, average interference and its variation in time can seriously jeopardize the CSI at the eNodeB. In this paper, we present an integration of inter cell interference coordination with CSI reporting by reducing the interference variability through controlled allocations. Results show that the entire CSI accuracy can be improved and so does the overall cell performance.

The next-generation 5G networks will integrate two technologies, cognitive radio and cooperative communication, which use radio spectrum opportunistically and efficiently, in addition, they enhance the reliability and the capacity of the system. In this paper, we present a novel power control scheme based on a relaxed constraint at cognitive relay network under both the outage probability limit (OPL) of the primary system and the interference constraint limit (ICL). We show how to transform the optimization problem of the condition on the OPL and the ICL into a condition on the channel, so that the cognitive user observes the channel from cognitive source to primary receiver, and control its transmit power based on the channel condition. We derive the closed-form expressions of the outage probabilities over independent but not necessarily identically distributed Nakagami-m fading channels. By using the theoretical analysis and from the numerical results, firstly, we show that the proposed power control scheme which based on both the OPL and the ICL achieves better performance in underlay spectrum rather than the traditional which based only on the interference constraints. Secondary, we show that the proposed scheme allows lower power consumption at cognitive side while the performance of cognitive relay network is improved and the QoS of primary system is guaranteed in parallel.

In this paper, we develop a unifying H-transform analysis for the channel capacity in H-fading and degree-2 irregular H-fading using the new systematic language of transcendental H-functions. By virtue of Mellin and convolution operations involved in the Mellin transform and Mellin convolution of two H-functions, the H-transform for the channel capacity culminate in again H-functions. Using the algebraic asymptotic expansions of the H-transform, we further quantify the high signal-to-noise-ratio (SNR) power offset and the low SNR slope of the capacity in a unified manner.
