Abstract
A method and network entity for enabling higher order modulation (HOM) mode support for HOM capable wireless devices. The method includes determining a legacy mode power offset value for HOM mode capable wireless devices in legacy modulation mode and calculating a power headroom value for sending downlink data to the HOM mode capable wireless devices. When the power headroom value exceeds a threshold value, the HOM mode support for the HOM mode capable wireless devices is enabled using the identified legacy mode power offset value. When the power headroom value does not exceed the threshold value, and a HOM mode power offset value is available, the HOM mode power offset value being less than the legacy modulation mode power offset value, the HOM mode support for the HOM mode capable wireless devices is enabled using the HOM mode power offset value.
