Abstract: The present invention relates to a method for operating a base station (21) in a wireless radio network. The base station (21) comprises a plurality of antennas (22) for transmitting radio frequency signals between the base station (21) and a user equipment (UE1, UE2, UE3). According to the method, at each antenna (22) a training signal sent from the user equipment at a first point in time (t1) is received and for each antenna a corresponding first configuration parameter (P1) is determined based on the training signal received at the corresponding antenna at the first point in time (t1). Furthermore, at each antenna (22) a training signal sent from the user equipment at a second point in time (t2), which is different from the first point in time (t1), is received and for each antenna (22) a corresponding second configuration parameter (P2) is determined based on the training signal received at the second point in time (t2).

Abstract: A portable communication device is equipped with a touch input device configured to provide key press functionality and scrolling functionality. The touch input device is electronically defined to include a plurality of key press areas separated by grey zones. The portable communication device is configured to provide scrolling functionality in response to detection of sequential user contact with multiple key press areas and an intervening grey zone within a predetermined timing trigger.
