Abstract

Systems and methods are provided for optimizing resource usage by a network entity that detects a first channel condition for a first radio access technology (RAT) and a second channel condition for a second RAT. The network entity determines whether the first channel condition comprises a higher interference level than the second channel condition and also determines power consumption constraints. If the first channel condition comprises a higher interference level than the second channel condition, the network entity reassigns at least one antenna from the first RAT to the second RAT based at least in part on the power consumption constraints. In some embodiments, systems and methods are also provided for determining whether an access point serving an access terminal is a large cell base station or a small cell base station and determining a power management action for the access terminal.
