Patent ID: 8554257

Claim:
A method performed at a base station in a wireless network, comprising: collecting one or more operational measurements of a cell area corresponding to the radio base station providing a wireless service to a user equipment; determining a range of transmission parameter values for the user equipment based on the collected one or more operational measurements; selectin a predetermined number of reference transmission parameter values based on the range of the transmission parameter values, the predetermined number being at least two; and providing the selected predetermined number of reference transmission parameter values to the user equipment, wherein the range of transmission parameter values are for use by the user equipment to determine one or more transmission parameters to be applied at the user equipment when the user equipment transmits information on a channel to the base station, wherein an actual number of transmission parameter values in the range is greater than the predetermined number such that the range includes one or more transmission parameter values that are not included in the reference transmission parameter values, and wherein in the act of selecting the predetermined number of reference transmission parameter values, the reference transmission parameter values are selected in consideration of an interpolation used by the user equipment to determine the one or more transmission parameter values not included in the reference transmission parameter values.
