[en] This work addresses scheduling in a cognitive radio
scenario where a minimum throughput for the downlink primary
network (PN) is guaranteed to each user with an associated
violation probability (probability of not obtaining the guaranteed
throughput). The primary network is surrounded by multiple
downlink secondary networks, each aiming to maximize its
network throughput. Scheduling in PN is performed independent
of the secondary networks. Some information about the PN
is available at the central scheduler that is responsible for
scheduling the secondary networks. The contribution of this work
is to apply a novel scheduler to the PN which is more robust to
QoS degradations resulting from the secondary networks than
other state of the art schedulers. This is validated by numerical
simulations of the cognitive radio network.
