Transmission quality measurement in a communication network

A method for measuring the transmission quality between a base station (BS) and at least one remote station (RS) in a communication network (N) having at least one channel (c) for transferring signals between said base station (BS) and said at least one remote station (RS), wherein the base station (BS) uses a channel (co) allocated to it, while channels (CU1, ..., cun) available for the station base (BS), but they are not used by it, a channel quality (Q (co)) for the channel used, wherein the channel quality for the unused channels (Q (CU1) is measured, is measured. .., Q (cun)), a period (T (co)) quality measurement indicative transmission time interval between two measurements of quality of successive Q transmission (co) for the used channel, according determined with a ratio of a quality measure for the used channel Q (co) and the quality measure of an unused channel (Q (CU1), ..., Q (cun)); while a period (T (cu)) quality measurement indicative transmission time interval between two measurements of quality of successive transmission (Q (cu)) for a given channel unused (CU) according to the relationship defined a measure of quality for the given channel unused (Q (co)) and channel quality measure as unused Q (cu).
