Abstract:
Embodiments of the present invention provide methods, systems and apparatuses for optimizing downlink path loss (PL) measurements in time division duplex (TDD) systems enabling fast power control targeting to decrease fading margin. In one embodiment, a method of power control in a long term evolution time division duplex (TDD) system is provided. The method includes controlling a length of a path loss measurement filter based on an allocation type. A width and frequency position of the path loss measurement filter is made dependent on the allocation type.
