Title: ON/OFF TIME MASK FOR SHORT TTI
Abstract:
According to some embodiments, a method for use in a user equipment (UE) of transmitting wireless signals according to an ON/OFF time mask comprises: obtaining a transmission time interval (TTI) for operating a wireless signal between the UE and a cell; and determining an ON/OFF time mask from a plurality of ON/OFF time masks based on the obtained TTI. The ON/OFF time mask specifies a length and position of transient periods for power ramp up and ramp down with respect to an associated TTI. The method further comprises transmitting the wireless signal in the cell according to the determined ON/OFF time mask. For example, determining the ON/OFF time mask may comprise determining one ON/OFF time mask if a length of the obtained TTI is below a threshold, and determining a different ON/OFF time mask if the length of the obtained TTI is equal to or above the threshold.
