As opposed to the previous work which deals with outdoor devices only, we consider a non-homogeneous environment in which both indoor and outdoor devices exist with the different intensities and channel characteristics. A stochastic geometry model with various system parameters, including inband emission and channel parameters, has been employed to derive the average number of devices discovered within the given time constraint. It has been found from our analytical results that the in-band emission is a most critical factor that limits the discovery performance, especially in the mixed environment, implying that its performance can be improved significantly by any means of reducing the in-band emission.","PeriodicalId":299228,"journal":{"name":"2014 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633921","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}

Two-types of extreme beamforming schemes at small cell base stations (BSs) are considered based on local channel state information (CSI) at transmitter: i) maximizing the desired channel gain and ii) minimizing the interference generated by each small cell base station (BS). Then, we propose a beamforming scheme that minimizes weighted generating-interference in pursuit of enhancing the achievable rate. In particular, an additional scalar information exchange is assumed between the BSs via a low-rate interface such as the X-2 interface in the 3GPP standards. By carefully choosing the weight coefficients based on the signal-to-interference-and-noise-ratios (SINRs), the scheme balances between these two philosophies - egoism and altruism. Simulation results show that there exists a trade-off between the amount of CSI knowledge and the achievable rate.","PeriodicalId":299228,"journal":{"name":"2014 International Conference on Information and Communication Technology Convergence (ICTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129067503","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}
