Title: Coordinated Scheduling and Beamforming for Multicell Spectrum Sharing Networks<\/p>\n
Abstract:\u00a0 We consider the downlink of a multicell network where neighboring multi-antenna base stations share the spectrum and coordinate their frequency and spatial resource allocation strategies to \u00a0improve the overall network performance. The objective of the coordination is to maximize the number of users that can be scheduled, meeting their quality-of-service requirements with the minimum total transmit power. The coordinated scheduling and multiuser transmit beamforming problem is combinatorial; we formulate it as a mixed-integer \u00a0second-order cone program and propose a branch & bound algorithm that \u00a0yields the optimal solution with relatively low-complexity. The algorithm can be used to motivate or benchmark approximation methods and \u00a0to numerically evaluate the gains due to spectrum sharing and coordination.<\/p>\n
Bio: Lei Yu received his Ph.D. degree in Electronic Engineering from University of Sheffield, UK, in 2010, M.Sc. degree in Signal Processing and Communications from University of Edinburgh, UK, in 2005, and B.Eng. degree in Communication Engineering from Xidian University, China, in 2004. He joined Communication Systems Division, Department of Electrical Engineering, Link\u00f6ping University, Sweden in March 2010 as a postdoctoral researcher. He is currently working on the project of EU FP7 SAPHYRE. His research interests include: robust beamforming, stochastic and array signal processing, and convex optimization.<\/p>\n","protected":false},"excerpt":{"rendered":"
