Whittle Index Policy for Multichannel Scheduling in Queueing Systems
Saad Kriouile, Maialen Larranaga, Mohamad Assaad
In this paper, we consider a queueing system with multiple channels (or servers) and multiple classes of users. We aim at allocating the available channels among the users in such…
Asymptotically Optimal Delay-aware Scheduling in Queueing Systems
Saad Kriouile, Mohamad Assaad, Maialen Larranaga
In this paper, we investigate a general delay-aware channel allocation problem where the number of channels is less than that of users. Due to the proliferation of delay sensitive…
Heterogeneous Doppler Spread-based CSI Estimation Planning for TDD Massive MIMO
Salah Eddine Hajri, Maialen Larrañaga, Mohamad Assaad
Massive multi-input multi-output (Massive MIMO) has been recognized as a key technology to meet the demand for higher data capacity and massive connectivity. Nevertheless, the numb…
Queue-aware Energy Efficient Control for Dense Wireless Networks
Maialen Larranaga, Mohamad Assaad, Koen De Turck
We consider the problem of long term power allocation in dense wireless networks. The framework considered in this paper is of interest for machine-type communications (MTC). In or…
Asymptotically optimal pilot allocation over Markovian fading channels
Maialen Larranaga, Mohamad Assaad, Apostolos Destounis +1
We investigate a pilot allocation problem in wireless networks over Markovian fading channels. In wireless systems, the Channel State Information (CSI) is collected at the Base Sta…
