Abstract: A power control method in accordance with the present invention synchronizes the transmit power levels at the base stations currently serving a mobile station and an initial transmit power level of a new target base station being added in a diversity handover situation. At the beginning of the handover, a radio network controller orders the serving base stations to measure their respective transmit powers to the mobile station. Each serving base station then measures its transmit power to the mobile station and reports the power level measurements to the radio network controller. An initial transmit power setting is determined for the target base station, and new transmit power settings are determined for the serving base stations synchronized for example to a particular time (t0).

Abstract: A plastic gutter is designed with a longitudinally extending bead (5) under an outwardly facing lip (4) and a corresponding longitudinally extending bead (5) on the inside of the rear part. At least at the end of each length of gutter the longitudinally extending beads have been machined in such a manner that material has been removed at regular intervals so that the remaining material constitutes one or more locking pieces (6).An assembly piece (7) with a rubber packing (8) for assembling adjoining lengths of gutter, for example, has a number of locking holes (9) in an outwardly facing lip (11) and a number of corresponding locking holes (9) in a bent edge part (10) at the rear.There is hereby obtained a gutter which is both quickly and easily mounted and taken down and where the parts are nevertheless securely held together so that an axial movement between the parts will not occur.
