Grouping-Based Interference Alignment With IA-Cell Assignment in Multi-Cell MIMO MAC Under Limited Feedback
Cao, Pan; Zappone, Alessio; Jorswieck, Eduard (2016-03-01)Interference alignment (IA) is a promising technique to efficiently mitigate interference and to enhance the capacity of a wireless communication network. This paper proposes a grouping-based interference alignment (GIA) ... -
Low-Complexity Energy Efficiency Optimization with Statistical CSI in Two-Hop MIMO Systems
Zappone, Alessio; Cao, Pan; Jorswieck, Eduard (2014-11-30)Energy-efficient resource allocation in a single-user, amplify-and-forward (AF), relay-assisted, multiple-input-multiple-output (MIMO) system is considered in this paper. Previous results in this area assume that perfect ... -
Semidynamic Green Resource Management in Downlink Heterogeneous Networks by Group Sparse Power Control
Cao, Pan; Liu, Wenjia; Thompson, John; Yang, Chenyang; Jorswieck, Eduard (2016-05-31)This paper addresses an energy-saving problem for the downlink of a cloud-assisted heterogeneous network (HetNet) using a time-division duplex (TDD) model, which aims to minimize the base stations (BSs) sum power consumption ...
