This New Downlink Control Information Design with two new bits extends the Downlink Demodulation Reference Signal (DMRS) so that the Physical Downlink Shared Channel (PDSCH) shall be processed and mapped to Resource Elements (RE) mapping and Quasi-Co-Location (QCL) parameter for a User Equipment UE. The new design was analyzed for Multi-user MIMO (MU-MIMO) and Coordinated Multi-point Transmission (CoMP) techniques. The analysis and simulation results indicate that DCI format 2D with the additional bits used with the CIF field are beneficial for both MU-MIMO and CoMP.","PeriodicalId":441229,"journal":{"name":"2013 Wireless Telecommunications Symposium (WTS)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114671545","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}

Interference management includes receiver processing, interference randomization by frequency hopping, and interference coordination through resource usage restrictions imposed by frequency and power planning. In this paper, we present a novel semi-static interference coordination scheme for cellular systems to improve the cell-edge performance with little penalty to the overall system throughput. The proposed scheme consists of two stages, semi-static distributed resource pre-allocation and power control. Here, power control with a fixed adjusting factor and an adaptive power control algorithm are both considered. Simulation results show that the proposed scheme outperforms a number of reference conventional interference coordination schemes in terms of cell-edge and overall system throughput especially in high-load scenarios.","PeriodicalId":441229,"journal":{"name":"2013 Wireless Telecommunications Symposium (WTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128967124","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}
