Interference management and interference alignment in wireless networks
Abstract
Interference mitigation (e.g., interference suppression and/or interference cancellation) in a wireless communications system may include interference alignment techniques. Interference alignment may be performed to concurrently mitigate the effects of multiple types of interference (e.g., inter-cell interference and intra-cell interference). Interference management using interference alignment may enhance spectral efficiency in an interference-limited communications system, such as a wireless communications system (e.g., a cellular system). Interference alignment techniques may be applied to a homogeneous wireless communications system (e.g., including one or macro base stations). Interference alignment techniques may be applied to a heterogeneous wireless communications system (e.g., including one or macro base stations and one or more overlaid low-power nodes, such as small cells, remote radio heads (RRHs), or the like).
