Abstract: A method scheduling allocation of radio resources in a cellular network, including: selecting at least one first user equipment for performing a first type data exchange based on Coordinated Multi-Point technique and a second type data exchange not based on Coordinated Multi-Point technique, and selecting at least one second user equipment for performing only the second type data exchange; selecting at least one network node for performing the first type data exchange with the at least one first user equipment and the second type data exchange with at least one among the first and second user equipment; determining, for the at least one network node, a radio resource parameter indicative of a number of radio resources to be allocated for the first type data exchange and a number of radio resources to be allocated for the second type data exchange; allocating the radio resources based on the radio resource parameter.

Abstract: A tunable delay line for radiofrequency or microwave frequency applications consists of at least one ridge waveguide in which the ridge is movable in the waveguide body so as to vary the width of an air gap defined between the longitudinal end surface of the ridge and a confronting member of the waveguide. The ridge is moved by an actuator external to the waveguide body.

Abstract: A differential delay element for use, e.g., in selectively delaying RF signals in telecommunication systems includes a first microstrip circuit and a second microstrip circuit arranged side-by-side in a facing relationship. The first microstrip circuit defines a first delayed travel path for a first signal from a first input port to a first output port and the second microstrip circuit defines a second delayed travel path for a second signal from a second input port to a second output port. A perturber is arranged between the first and second microstrip circuits, displaceable toward and away from the first and second microstrip circuits, so that when the distance of the perturber to one of the microstrip circuits increases, the distance of the perturber to the other of the microstrip circuits decreases and viceversa.
