It thus makes conventional baseband precoding, such as zero-forcing (ZF) which is deemed virtually optimal in the large array regime, impractical. In this paper, we consider the RF chain limitations present in large mmWave multiuser systems and propose to approach the desirable yet infeasible baseband ZF precoding by essentially steering the beam towards each user's strongest path, termed MUBS, through analog processing at the RF domain. Rates achieved by both baseband ZF and the proposed MUBS precoding are then derived in a closed form. We further study the rate loss of MUBS relative to the upper bound imposed by ZF precoding and find that the gap converges to a finite limit as the transmit antenna number Nt goes large. Since the achievable rate of ZF grows without limit as Nt increases, the proposed MUBS scheme thus promises to achieve most of ZF rates at large Nt. Numerical results are also provided to validate the desirable performance of the proposed MUBS scheme.","PeriodicalId":353402,"journal":{"name":"2014 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"161 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113981774","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}

However, the dense and random deployment of femto-cells and their uncoordinated operations cause severe inter-cell interference. This paper studies cluster-based wireless resource management issues in ultra-dense networks (UDN). Firstly, a modified K-means algorithm is performed in the clustering process. A reasonable number of clusters is derived instead of the predefined value as the input parameter. The wireless resource management is investigated to maximize the sum-throughput in UDN. Specifically, this paper propose a two-stage resource management scheme to solve this problem. In the first stage, primary resource allocation is performed by using a greedy search algorithm in each cluster. In the second stage, a supplementary allocation algorithm (SAA) is presented to assign the remainder subchannels. Finally, numerical results show that the proposed scheme achieves a satisfying performance in terms of average SINR, the system throughput, and the spatial spectrum efficiency, which provides guidelines for the practical dense deployment of femtocells.","PeriodicalId":353402,"journal":{"name":"2014 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123312869","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}
