Intercell interference (ICI) is one of the most critical factors affecting performance of cellular networks. In this paper, we investigate a joint link adaptation and user scheduling problem for a multicell downlink employing hybrid automatic repeat request (HARQ) techniques, where the ICI exists among cells. We first propose an approximation method on aggregated ICI for analyzing an effective signal-to-interference-and-noise...
We consider new Dynamic Network Architecture (DNA) which provides significant soft capacity in the network enabling a wide range of adaptations to traffic demand variations without any change in the fixed network infrastructure. To maximize the system throughput we propose a new second order cone programming (SOCP) based algorithm to optimize jointly the access point (AP) selection and the downlink...
Coordinated Multi-Point (CoMP) transmission is a promising technique for LTE-Advanced systems, especially due to the enhanced throughput performance of cell edge users. In this paper, we investigate joint transmission (JT) and coordinated beamforming (CBF) with quantized and delayed feedback, and we derive ergodic rate and outage probability expressions assuming large-scale fading (pathloss), small-scale...
We consider lifetime quality-of-experience (QoE) management for video-on-demand (VoD) users in WiMAX networks. For efficient resource utilization while enhancing user experience, we propose run-time load balancing through joint scheduling among multiple base stations (BSs), referred to as macro scheduling. Macro scheduling employs a utility-maximization approach. To achieve long-term proportional...
In this paper, we consider the problem of quality of service (QoS) provisioning for K users sharing a downlink wireless channel. The channel to each user is assumed to be a block Rayleigh fading channel. We develop simple and efficient scheduling schemes which can yield substantial capacity gain. Our approach is to maximize the throughput in subject to a given delay QoS constraint by choosing the...
