Uplink Power Control Based on Multiple Reference Signals

Abstract:

According to certain embodiments, a method implemented in a wireless device comprises determining configuration data representing a set of configurations. The method comprises receiving at least one reference signal from a transmission point. The receiving of the at least one reference signal is performed in accordance with a configuration selected from the set, wherein the configuration is related to uplink power control and is specific to an uplink channel or signal or a group thereof. The method comprises measuring a propagation-related quantity on the basis of the at least one reference signal and deriving an uplink power setting on the basis of the measured propagation-related quantity.
