Abstract
Methods, systems, and devices are described for hierarchical modulation and interference cancellation in wireless communications systems. Various deployment scenarios may be supported that may provide communications on both a base modulation layer as well as in an enhancement modulation layer that is modulated on the base modulation layer, thus providing concurrent data streams that may be provided to the same or different user equipments. Various interference mitigation techniques may be implemented in examples to compensate for interfering signals received from within a cell, compensate for interfering signals received from other cell(s), and/or compensate for interfering signals received from other radios that may operate in adjacent wireless communications network.
