The cost for existing coordination schemes with joint processing is the heavy exchange of channel state information and signal information over backhaul links. In this paper, we propose a decentralized BS processing method for the downlink of CoMP systems. Its key feature is that each BS performs decentralized processing without requiring any explicit information exchange between BSs. Unlike existing work, each BS maximizes the rate for multiple intra-cell users and cancels inter-cell interference in a decentralized manner.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"49 4-5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114162270","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}

Relay station (RS) enables data transmission between base station and end user when the channel is not good for transmission. Besides, one relay station also communicates with a pair of other relay stations to accomplish the communication via multi-hop relay path. An efficient scheme for path selection and per user throughput in the multi-hop relay network is an important issue to fulfill the purpose of a relay station. In this paper, we proposed a cross-layer tree based path construction mechanism to adjust the system deployment when new mobile station (MS) access to the network. Furthermore, an interference based path selection scheme is suggested to facilitate the improvement of per-user throughput as well as system throughput in multi-hop relay network.

The system model assumes (i) arbitrary topologies, (ii) arbitrary call arrival rates, (iii) multiple links transmitting simultaneously over shared interference-limited channels, and (iv) transmitters updating their powers to maintain a predefined signal-to-interference and noise ratio (SINR) at the receiver. Departing from our own theoretical framework on the computation of the dominant eigenvalue of the network information matrix, we discuss an accurate MAC scheme that uses interference measurements as its only decision-making input. By accuracy is meant that the MAC scheme grants channel access to all links with achievable target SINRs and rejects others. In contrary to other schemes, our approach allows once-admitted links to continuously monitor the achievability of their SINR targets without any overhead. However, the initial admission decision of passive links relies on energy-consuming channel probing, which can be protracted in networks with high channel reuse. While maintaining the accuracy and reliability, we reduce the overall call admission delay and energy usage of the MAC scheme by employing simple techniques for future prediction by data estimation/extrapolation. Power control based on Kalman filtration is suggested for noise suppression. Numerical simulations demonstrate the potential of the proposed scheme.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114476746","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 blind NDMA method using independent component analysis (ICA), named ICA-NDMA, has been shown to overcome the difficulties of synchronization and orthogonal identification codes required by the training-based NDMA protocols. In this paper, we propose a novel blind collision resolution strategy by employing cooperative transmission in ICA-NDMA. When K-node collision happened, a cooperative transmission mechanism is adopted to collect different superposition of the K nodes' packets in the following slots. Moreover, a cooperative blind detection algorithm is intro- duced to determine the number of collision nodes. Finally, with ICA, the destination can retrieve the original packets through processing the collided packet and the signals forwarded by relays. Simulation results show that, the proposed method can work effectively under both fast-varying and slow-varying channels, the performances of average packet delay and maximum stable throughput are better than ICA-NDMA.","PeriodicalId":325246,"journal":{"name":"2010 IEEE 71st Vehicular Technology Conference","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122103288","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 the MIMO transmissions, we consider capacity-achieving scheme and beamforming. We compare the total utility for both multi-flow transmission and selection diversity.

Considering different bandwidth requirement of secondary users, the proposed greedy admission algorithm takes limited aggregation capability into account.
