This paper presents an integrated model to predict the traffic flow of base station. Firstly, we predict the traffic flow with basic Echo State Network (ESN) and Autoregressive Integrated Moving Average (ARIMA). Algorithms show poor prediction performance due to the existence of mutation values. Therefore, we add wavelet transform into our model to decompose traffic flow, which could make traffic signal smooth and easy to predict. Besides, through the wavelet decomposition and single reconstruction of the original traffic flow data, we obtain data sequences with a better regularity. Then we can get the final predicted traffic flow data with a linear sum of the single prediction. Experimental result shows that the integrated model can achieve a better prediction accuracy by comparing to ESN and ARIMA. The integrated model can decrease the Mean Absolute Percentage Error (MAPE) by 6% and reduce the Normalized Root Mean Square Error (NRMSE) to some extent.","PeriodicalId":299723,"journal":{"name":"2018 24th Asia-Pacific Conference on Communications (APCC)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114446923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For massive MIMO, quantities of antennas are utilized to provide better coverage, which brings challenge for implementation as well as opportunity for improving multi-user (MU)-MIMO performance. To provide better performance for MU-MIMO, high resolution CSI feedback was introduced in Rel.14. Base stations can acquire more accurate channel information from high resolution CSI to facilitate scheduling for multiple users with reduced inter-user interference. However, high resolution CSI feedback specified in current 3GPP still has large room to be improved due to big gap between current CSI feedback and ideal CSI feedback. In this paper, we investigate possible enhancement directions towards high resolution CSI, e.g., to improve the quantization resolution by combining more beams, to increase the supported rank, etc. High resolution codebook construction and higher rank multi-user scheduling schemes are provided. System evaluation is performed to verify the effectiveness of those schemes. Simulation results show that improving quantization resolution can bring decent performance gain, and supporting higher ranks can bring larger performance gain. Both schemes will introduce large overhead. To balance performance and overhead, supporting higher rank high resolution is preferred. The challenges to specify these schemes are also analyzed.","PeriodicalId":299723,"journal":{"name":"2018 24th Asia-Pacific Conference on Communications (APCC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121392391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we propose a novel antenna pattern, named multi-level flat-top (MLFT) antenna pattern, to approximate the actual antenna pattern, and apply it to millimeter wave (mm-wave) cellular networks. To study the benefits of directional antenna arrays in depth, we derive the exact expression for the coverage probability of the typical user and its upper bound as well as their corresponding asymptotic expressions. The results show that the proposed antenna pattern provides a better tradeoff between the accuracy and the tractability in terms of both antenna pattern and theoretical analysis than previous models. In addition, the coverage probabilities for different antenna sizes can be asymptotically characterized by a horizontal shift (in dB) with each other for identical Nakagami fading parameter.","PeriodicalId":299723,"journal":{"name":"2018 24th Asia-Pacific Conference on Communications (APCC)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123452584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hardware of the tester can be treated as an integrated radio frequency (RF) transmission system with an embedded additive white Gaussian noise (AWGN) module. The FPGA-based RF system can generate at most 10 independent channels (ICs) with multiple rolling factors. Multiple symbol rates from 2 Ksps to 34 Msps can be supported with an appropriate multistage up-sampling processing. Furthermore, at most 640 sub-channels can be generated with the help of poly-phase filter banks and a well-designed FPGA realization of quadrature phase shift keying (QPSK) modem. The precomputation and test results show that a high dynamic range of transmitting and receiving signal levels can be supported.
