Abstract
Devices and methods are provided for transmit power control in a wireless communication environment. In one embodiment, the method may involve measuring an interference amount over at least one of a sub-band and a full bandwidth. The method may involve assigning a level to the measured interference amount, the level comprising one of an overloaded level and an underloaded level. The method may involve encoding the level as an overload indicator, the overload indicator being conditioned on the sub-band such that the overload indicator includes enhanced layer symbols regarding the level of the measured interference amount. The method may involve conveying the overload indicator to at least one mobile device.
