Theoretical outage capacity analysis for resource allocation in a downlink orthogonal frequency division multiple access (OFDMA) with limited feedback is presented. OFDMA system with practical resource fair round robin scheduler and erroneous feedback channel is considered. Two feedback methods are analyzed and compared. In the set best-M feedback method,(More)
In this paper we present system level simulation results for a cooperative moving relay node (MRN) system deployed on a high speed train (HST). Recently interest has grown in using MRNs to provide enhanced cellular coverage to users in public transport, particularly HSTs, of which the modern construction materials and techniques cause high vehicle(More)
Self organizing network techniques are needed to manage serious two-tier interference in an ad hoc operation of dense femtocell deployment. This paper considers downlink frequency domain inter-cell interference coordination (ICIC) in femtocell deployment. The studied resource partitioning method works such that each active femtocell may adapt, determine,(More)
Information theoretical outage capacity results for MIMO-OFDMA systems are expressed in this paper. So called best-M feedback is used for OFDMA resource allocation. Transmit antenna selection (AS) and space-time block coding (STBC) schemes as well as simple spatial division multiple access (SDMA) with zero forcing detection are analyzed. The outage capacity(More)
This paper studies the resource allocation for orthogonal frequency division multiple access (OFDMA) in a fixed amplify-and-forward (AF) relay link. We express closed-form average capacity results for the system when frequency allocation is based on limited and imperfect feedback information and multiple antennae are assumed at the relay node (RN) and the(More)
European Telecommunication Standards Institute (ETSI) is standardizing the 3GPP Long Term Evolution Advanced (LTE-A) relay nodes (RNs) which are intended to be used for providing enhanced cell edge coverage and capacity. We present simulation results on the prospected LTE-A mobile relay node (MRN) applications. The future vehicles can communicate with their(More)
