We study the effectiveness of using relay station nodes to enhance the spectral efficiency of multicast distribution under full coverage in a mobile wireless networks. Coloring oriented adaptive rate scheduling algorithms are considered, including such that temporally employ TDMA schedules with reuse levels of 1, 3, 4 and 7 over a cellular arrangement. These schemes are used to regulate multicast transmissions executed by base station and (when employed) relay station nodes. We examine the utility of using, in each cell, a single layer of placed three and six relay station (RS) nodes. We examine the optimal locations at which such RS nodes should be placed under symmetric deployment in each cell. Base stations coordinate the scheduling of base station (BS) and RS nodal transmissions by employing two-phase reuse schemes. We show that when the inter-site distance (ISD), identifying the range between BSs, is lower than certain threshold levels, it is most effective to employ a reuse-3 scheduling scheme that is based on direct (1-hop) multicast transmissions by base station (BS) nodes to associated mobile station (MS) clients. In turn, under longer ISD ranges (e.g., as employed in less dense cellular layouts), the spectral efficiency of the system can be significantly enhanced by using a joint scheduling and routing scheme that makes use of a relay aided two-hop coverage operation. We also show that it is then more effective to deploy in each cell 3 rather than 6 RS nodes.","PeriodicalId":290330,"journal":{"name":"2012 IEEE Globecom Workshops","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114668228","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 uplink is a special case of a multi-source, single destination relay network. The downlink is a special case of a broadcast relay network. Recently, novel uplink and downlink schemes called Compute-and-Forward and Reverse Compute-and-Forward were proposed, showing attractive performance-complexity tradeoff in certain regimes. In this work we focus on the ATs (uplink) or UTs (downlink) selection problem. For the uplink, for a given set of active UTs, we wish to select a subset of the ATs such that the resulting system matrix is full-rank and the sum rate is maximum. For the downlink, for a given set of transmitting ATs, we wish to select a subset of UTs such that the resulting system matrix is full-rank and the sum rate is maximum. We present antenna and user terminal selection algorithms suited for the proposed cloud base station architecture and demonstrate by simulation, in a realistic environment with fading and pathloss, that selection essentially eliminates the problem of rank deficiency of the system matrix, which represents the main performance impairment effect for a naive assignment of the active terminals.","PeriodicalId":290330,"journal":{"name":"2012 IEEE Globecom Workshops","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116580157","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}
