—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)
— Opportunistic user allocation and multiple antenna transmission provide significant performance enhancement in future wireless communication systems. In this paper, theoretical outage capacity analysis of user allocation in downlink orthogonal frequency division multiple access (OFDMA) with multiple antenna transmission and limited feedback is presented.(More)
