1.Paper

Title: Power Allocation for Orthogonal Multiple Access Relay Channel Allowing Intra-link ErrorsAuthors: Valtteri Tervo, Xiaobo Zhou, Pen-Shun Lu, Markku Juntti, Tad MatsumotoAbstract: Power and rate allocation is theoretically analyzed for an orthogonal multiple-access relay channel(MARC), where lossy transmissions are allowed in the source-relay links and the erroneous estimates are for-warded from the relay to the destination. Conventional decode-and-forward (DF) strategy forwards only correctlyreceived estimates and discards the erroneous. However, even the erroneous estimates can be utilized at the des-tination in order to improve the reliability of the received information sequences sent from source nodes. In thispaper, minimum power and maximum rate problems for the MARC system with lossy relaying are formulatedand the resulting nonconvex problems are solved via successive convex approximation (SCA). Numerical resultsshow that the system allowing erroneous relaying is superior in terms of the considered objectives compared to thelossless DF.

Title: Providing 10 Gbit/s in Downlink to a Mobile Terminal with Practical Array Design Beamforming Aspectsby Using Orthogonal MIMO BeamsAuthors: Tommi Tuovinen, Nuutti Tervo, Harri Pennanen, Aarno ParssinenAbstract: Orthogonal MIMO beam directions for spatially multiplexed data streams (SMDSs) and terminal arraylimitations with a steering angle are studied in this paper. As delivering SMDS for large distances is challenging,the research work studies a short-range indoor environment with line-of-sight (LOS) & non-LOS MIMO channelmodels for time-division duplex orthogonal frequency-division multiplexing 5G system. Radio frequency (RF)modelling method is utilized for link budget analysis where digital signal processing is abstracted to the mini-mum signal-to-noise ratio (SNR) requirements and RF system SNR described based on transmitter and receiverperformance related to output and input power levels. By limiting a terminal to six array elements at 10 GHz,

Page 10 (17)

it is shown that channel dynamic range, e.g., in LOS can even exceed some 45 dB between the best and worsteigen value-based beams. For some users, beam angle-of-arrivals were observed to vary even 100 degrees. Mobilearray steering range was shown to cause fundamental restrictions to capture SMDSs from wide beam angles withsufficient array gain. Achieved user data rates and power consumption are demonstrated at the end of this paper.

3.Paper

Title: On the Performance of Dynamic Multi-Source Multi-Antenna Multi-Relay Wireless NetworksAuthors: Jiguang He, Iqbal Hussain, Shen Qian, Markku Juntti, Tad MatsumotoAbstract: We investigate the average end-to-end outage probability of the multi-source, multi-antenna multi-relay,single destination network with dynamic topology. In particular, we calculate the average end-to-end outage prob-ability by taking into account the random access behavior of the sources, possible decoding outcomes at the relays,and imperfect channel state information at the relays for the relay-to-destination links. All the channels betweensource-to-relay and relay-to-destination pairs are assumed to suffer from spatially independent block Rayleigh fad-ing. Decode-and-forward relaying protocol is applied to all the relays. Numerical results show that if the numberof the users are greater than the number of antennas at all the relays, the outage probability exhibits an error floor.Furthermore, higher order diversity is obtained by increasing the number of relays. Additional performance gainis achieved by increasing the number of antennas at the relays.

4.Paper

Title: A Comparative Study of Different Relaying Strategies over One-Way Relay NetworksAuthors: Shen Qian, Valtteri Tervo, Jiguang He, Markku Juntti, Tad MatsumotoAbstract: We derive and compare the analytical outage probabilities of conventional decode-and-forward (DF),adaptive DF (ADF), compress-and-forward (CF), and lossy-forward (LF) relaying protocols over fading channels.A joint decoding is assumed at the destination to exploit the source-relay correlation for retrieving the originalinformation of the source. With DF, only if the information sequence can be decoded with an arbitrary low errorprobability at the relay, it will be forwarded to the destination. With ADF, the source retransmits the information,if a failure of the transmission happens on the source-relay link. With CF, the relay performs the Wyner-Zivcompression and forwards the compressed version to the destination. With LF, the relay node always forwardsdecoded information sequence to the destination even if a decoding error is detected. The impact of line-of-sight component in the fading variations for transmission chain is taken into account. It is shown that the outageprobability with the LF relaying is smaller than that with CF and DF relaying. ADF is superior to LF in terms ofoutage performance due to the feedback information.

Title: Validation of Deterministic Radio Channel Model by 10 GHz Microcell MeasurementsAuthors: Antti Roivainen, Pekka Kyosti, Veikko Hovinen, Claudio Dias, Nuutti Tervo, Marko Sonkki, GustavoFraidenraich, Matti Latva-ahoAbstract: This paper considers validation of a deterministic radio channel model utilizing wideband radio channelmeasurements at 10 GHz frequency. Multiple-input multiple-output radio channel measurements were carried outin urban microcell type of environment. The validation comprises of analysis and comparison of modeled prop-agation paths and measured propagation paths. From the measured data, the azimuth and elevation (3D) angles,gains and delays of propagation paths were estimated. With the deterministic model the propagation paths weremodeled by a map-based model utilizing simplified ray-tracing with buildings modeled as rectangular shapes. The3D map for the deterministic model was created based on the collected distance information of the measurementsite. Both line-of-sight (LOS) and non-line-of-sight (NLOS) propagation conditions were considered. Path losses,power delay profiles, and the directions of departure and arrival were used to validate the model. The path lossesare similar, and the directions of the modeled and measured paths match well.

Title: Effects of PA Nonlinearity and Dynamic Range in Spatially Multiplexed Precoded MIMO SystemsAuthors: Nuutti Tervo, Janne P Aikio, Tommi Tuovinen, Timo Rahkonen, Aarno ParssinenAbstract: In this paper, we study the effects of nonlinear distortion caused by RF power amplifiers (PAs) to theperformance of singular value decomposition-based linear precoding and spatial multiplexing (SM). The goal is todefine the requirements of the individual PAs in SM multiple-input multiple-output (MIMO) systems to enable rankN transmission. The distortion of the independent data streams are shown to be coupled in PA output. PolynomialPA model and antenna array factor are used to model the antenna patterns of the distortion components and it isshown that part of the distortion can be canceled by beamforming them to unharmful directions. The effects in16x4 MIMO system with 64-QAM modulated signals are demonstrated by simulating error vector magnitude ofindividual data streams in System Vue simulation environment. It is concluded that the signal dynamics betweenthe streams should be taken into account when designing PAs for future telecommunication systems.

Title: DRSS-based Factor Graph Geolocation Technique for Position Detection of Unknown Radio EmitterAuthors: Muhammad Reza Kahar Aziz, Khoirul Anwar, Tad MatsumotoAbstract: This paper proposes a new factor graph (FG) geolocation technique utilizing differential received signalstrength (DRSS) for location detection of a single static unknown (anonymous) radio wave emitter. The use ofDRSS-based FG (DRFG) technique is to solve the problem of conventional received signal strength (RSS)-basedFG (RFG) technique which is unable to estimate the position of a single static unknown radio wave emitter withoutthe knowledge of its transmit power knowledge. However, in practice, the transmit power information from thesignal transmitted by the unknown target emitter is unavailable. It should be noticed that the knowledge of thetransmit power of the target is necessary for calibration/reference of the RSS values of training signal sent fromthe monitoring spots. In this paper, we propose a new DRFG technique to eliminate the necessity of transmitpower information, and hence this technique successfully estimates the position of an unknown radio emitter. Theperformance of the proposed technique is evaluated in the terms of root-mean-square error (RMSE). The resultsconfirm that the proposed technique accurately estimate the location of unknown target, while the conventionalRFG fails when the transmit power of monitoring spots are unequal to the transmit power of the unknown target.

Title: Channel Dynamics and SNR Tracking in Millimeter Wave Cellular SystemsAuthors: Marco Giordani, Marco Mezzavilla, Aditya Dhananjay, Sundeep Rangan, Michele ZorziAbstract: The millimeter wave (mmWave) frequencies are likely to play a significant role in fifth-generation (5G)cellular systems. A key challenge in developing systems in these bands is the potential for rapid channel dynamics:since mmWave signals are blocked by many materials, small changes in the position or orientation of the handsetrelative to objects in the environment can cause large swings in the channel quality. This paper addresses theissue of tracking the signal to noise ratio (SNR), which is an essential procedure for rate prediction, handover andradio link failure detection. A simple method for estimating the SNR from periodic synchronization signals isconsidered. The method is then evaluated using real experiments in common blockage scenarios combined withoutdoor statistical models.

In this TS1 configuration the SR and SD link had low and the RD link high SNR. The Frame Success Rate (FSR)of both weak links is almost zero (FSR smaller 0.01), see Fig. 3.5. In the demo each frame is sent twice from thesource (i.e. 1 retransmission). Hence there are 4 corrupted copies arriving at destination. In TS1 lossy forwarding(LF) each frame is forwarded by the relay.

Figure 3.4: Setup for TS1

The RESCUE joint decoding (JD) is applied to the arriving frames. During the live demo the RESCUE approach(LF + JD) maintains connectivity (FSR larger 0.5) while in the baseline (standard decoder) the connection isbroken - FSR is (almost or exactly) equal to zero. This was presented on live plots with FSR time series. It wasalso observed that switching off the relay (reduction to a single link) would result in decreasing the FSR of the JDto something like 0.15.

RESCUE D5.5, v1.0

4. Summary

After the IWSDN workshop at the ICC 2015 the second international dissemination activity of the EU projectRESCUE was the Advanced PHY and MAC Layer Design for 5G Mobile Networks and Internet of Thingsworkshop at the 2016 European WIRELESS conference held in Oulu, Finland. This workshop was organizedjointly together with the 5G Innovation Center at Surrey. In contrast to the IWSDN workshop this activity aimed toprovide also an experimental demonstration of the RESCUE concept. Therefore a demo booth considering a USRPtestbed, video presentation and a poster area, summarizing the current status of the main four work packages fromthe RESCUE project, has been successfully built up.Both activities attracted a large audience, intensive discussion and overall a very good feedback from researcherand industrial representatives.
