The present invention concerns a method of providing communication over a mobile communication network (1) and components for providing communication over the communication network (1). The network (1) includes two or more fixed nodes (2a, 2b) each operating a fixed radio cell (3a, 3b) for serving one or more user equipments (4) via a first radio interface (5a, 5b). Each of these fixed radio cells (3a, 3b) is identified by a physical cell ID (6a, 6b) selected out of a set of N physical cell IDs. In addition, the network (1) includes one or more mobile relay nodes (7) served by the one or more fixed nodes (2a, 2b) via a second radio interface (8a, 8b). The mobile relay nodes (7) each operate a mobile radio cell (9) for serving one or more user equipments (4) via a third radio interface (10). Each of these mobile radio cells (9) is identified by a physical cell ID (6c) selected out of the set of N physical cell IDs. The method includes the step of dynamically assigning a physical cell ID (6c) of the set of N physical cell IDs to the one or more mobile radio cells (9).

摘要:
Systems and methods to measure signal propagation delay through objects. The system includes a controller, a single shot pulse generator, a first pulse/edge former, a multiplexer/demultiplexer, a second pulse/edge former, a timer, and a counter. The controller initializes the system, the clock and the counter. A pulse is sent from the single shot pulse generator to the first pulse/edge former. The pulse is propagated through the first pulse/edge former to the multiplexer, through a device under test, to the demultiplexer, and to the second pulse/edge former. The second pulse edge generator provides the pulse to the counter, which counts a predetermined number of pulses, and the clock, which measures the amount of time the counter counts the pulses. The propagation delay of the device under test is then calculated based on the counted number of pulses and the elapsed time measured by the clock.
