Abstract

Ένα σύστημα επικοινωνίας περιλαμβάνει ένα κανάλι δεδομένων κάτω ζεύξης για τη μετάδοση πακέτων δεδομένων από ένα πρωτεύοντα σταθμό σε ένα δευτερεύοντα σταθμό και κανάλια ελέγχου άνω ζεύξης και κάτω ζεύξης. Ο δευτερεύων σταθμός μετρά ένα ή περισσότερα χαρακτηριστικά του καναλιού δεδομένων και εκδίδει μια αναφορά προς τον πρωτεύοντα σταθμό, ο οποίος προσδιορίζει μια λειτουργική παράμετρο του καναλιού δεδομένων σε απόκριση στην αναφορά. Ο δευτερεύων σταθμός προσδιορίζει μέσο όρο χαρακτηριστικών καναλιού σε μια περίοδο μέτρησης. Το μήκος της περιόδου μέτρησης μπορεί να σηματοδοτείται από τον πρωτεύοντα σταθμό ή να προσδιορίζεται κατ' ευθείαν από τον δευτερεύοντα σταθμό. Σε μια εφαρμογή η επιλεγόμενη περίοδος εξαρτάται από την ταχύτητα (V) του δευτερεύοντος σταθμού. Αυτή προσδιορίζεται (604) από οποιονδήποτε από τους δύο σταθμούς και δοκιμάζεται για να προσδιορίζει (606) αν είναι εκτός της περιοχής για την τρέχουσα περίοδο μέτρησης. Αν είναι η περίοδος ρυθμίζεται εκ νέου (608).A communication system comprises a downlink data channel for transmitting data packets from a primary station to a secondary station and uplink and downlink control channels. The secondary station measures one or more features of the data channel and issues a report to the primary station, which specifies a functional parameter of the data channel in response to the report. The secondary station identifies average channel characteristics over a measurement period. The length of the measurement period may be signaled by the primary station or determined directly by the secondary station. In one embodiment the selected period depends on the speed (V) of the substation. This is determined (604) by either of the stations and tested to determine (606) if it is out of range for the current measurement period. If the period is reset (608).
