METHOD AND ARRANGEMENT IN A WIRELESS COMMUNICATIONS NETWORK FOR ADAPTATION OF POWER CONTROL SETTING

摘要

A method in a base station, for adapting Sounding Reference Signals (SRS) power control setting in a user equipment is provided. An SRS specific fractional pathloss compensation factor "asounding" value is decided based on a specific purpose for using SRS received from the user equipment. The asounding value is decided independent of a value of a data specific fractional pathloss compensation factor "adata" to be used for data transmission to the base station. The user equipment is informed to use the decided asounding value for adapting the SRS power control setting in the user equipment. This enables the user equipment to send SRS, using power according to the adapted power control setting.
