Downlink mobile OFDMA resource allocation with minimum user rate requests

Stefanatos, S.; Papathanasiou, C.; Dimitriou, N. (2009)

The problem of resource allocation (RA) in a downlink OFDMA system with minimum user rate requests is examined under the realistic scenario of partial (imperfect) channel state information (CSI) at the base station. The ...
Joint QoS multicast power / admission control and base station assignment: A geometric programming approach

Karipidis, E.; Sidiropoulos, N. D.; Tassiulas, L. (2008)

The joint power control and base station (BS) assignment problem is considered under Quality-of-Service (QoS) constraints. If a feasible solution exists, the problem can be efficiently solved using existing distributed ...
