Abstract
A radio base station node () of a telecommunications network comprises a baseband transmitter () and plural radio frequency (RF) paths () between the baseband transmitter () and an antenna system (). A measurement entity () is provided, preferably near the antenna system (), for making a measurement or comparison of a time of detecting of a power modulation for each of plural RF transmission paths (), e.g., a time of detecting of a power modulation for a first of the plural RF transmission paths and a time of detection of a power modulation for a second of the plural RF transmission paths. A transmission timing adjustment unit () uses the power modulation measurement or comparison for adjusting timing of transmission of signals for the plural RF transmission paths for obtaining a desired time alignment for the plural RF transmission paths.
