On multicast beamforming and admission control for UMTS-LTE
(2008)
Transmit beamforming for physical layer multicasting is emerging as an appealing transmission modality for next-generation cellular wireless systems, notably UMTS-LTE. Optimal design of the transmit beamformer(s) from a ...
Efficient Batch and Adaptive Approximation Algorithms for Joint Multicast Beamforming and Admission Control
(2009)
Wireless multicasting is becoming increasingly important for efficient distribution of streaming media and location-aware services to mobile and hand-held devices, network management, and software updates over cellular ...
Joint multiuser downlink beamforming and admission control: A semidefinite relaxation approach
(2007)
Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UMTS, 802.16e). ...
A second-order cone deflation approach to joint multiuser downlink beamforming and admission control
(2007)
Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UMTS, 802.16e). ...
Convex approximation algorithms for back-pressure power control of wireless multi-hop networks
(2011)
Cross-layer design and operation of wireless networks has attracted significant interest in the last decade, yet some basic problems in the area remain unsolved. In this paper, we consider the joint routing and power control ...
Convex Approximation Algorithms for Back-Pressure Power Control
(2012)
Throughput-optimal multihop wireless network operation entails a key physical-layer optimization problem: maximizing a weighted sum of link rates, with weights given by the differential queue backlogs. This emerges in joint ...
Distributed back-pressure power control for wireless multi-hop networks
(2012)
A key problem in wireless networking is how to choose a link activation schedule and associated powers in concert with routing decisions to optimize throughput. Back-pressure control policies are optimal in this context, ...
Convex approximation techniques for joint multiuser downlink beamforming and admission control
(2008)
Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UNITS, 802.16e). ...
Joint multicast beamforming and admission control
(2007)
Wireless multicasting is quickly emerging as an important enabling technology for mass content distribution to mobile hand-held devices. With channel state information at the transmitter, it is possible to tailor transmissions ...
