Abstract: Disclosed is a method which includes determining a traffic load situation and determine a category for the traffic load situation. The method also includes determining, based on the traffic load situation, one or more groups of digital to analog converters to be used, wherein the one or more groups have different resolutions for digital to analog conversions. The method may further include activating the determined one or more groups of digital to analog converters for transmitting signals. Additionally, the method may include transmitting the signals using multiple antennas.
