The planning and optimization of UMTS WCDMA radio networks is a very complex and challenging procedure. In order to obtain accurate results, this planning must take into account key WCDMA features, such as soft handover (SHO). However, the optimization of base station (BS) configuration considering this feature has not been investigated in previous work. In(More)
The issue of fairness and throughput trade-off in UMTS WCDMA network planning is discussed in this paper. The employed radio resource management (RRM) fully supports rate adaptation and hence, new potentials arise in terms of system throughput and fairness. The authors study four low complexity RRM algorithms that perform efficient rate adaptation in order(More)
The opportunistic beamforming (OB) technique in multicellular OFDMA networks is investigated in this paper. Three cross-layer radio resource management (RRM) algorithms for OFDMA operational scenarios are considered. These algorithms build upon typical network planning practices for OFDMA systems. The first two implement an OFDMA network with opportunistic(More)
—The opportunistic beamforming (OB) technique in multicellular OFDMA networks is investigated in this paper. For this reason, three cross-layer radio resource management (RRM) algorithms for OFDMA operational scenarios that are based on typical resource allocation targets such as minimization of transmit power, maximization of throughput and interference(More)
