Power control for a physical uplink control channel based on length parameter

摘要

Systems and methods for performing power control of a physical channel in a communication system are provided. In one exemplary embodiment, a method in a wireless device of performing power control of a physical channel in a wireless communication system may include determining a transmission power for a transmission on the physical channel according to a power control loop. Further, the loop may specify the transmission power based on at least one parameter. Also, a value of the at least one parameter may be dependent on which of different transmission time interval (TTI) lengths defined as usable on the physical channel is selected for the transmission on the physical channel.
