A method of determining a signal quality parameter in a radio communications device includes: measuring a signal error parameter of a received signal (); comparing said measured signal error parameter to a threshold level (), and determining the signal quality parameter on the basis of a reference signal error parameter value () in the event that the measured signal error parameter value is less than the threshold level ().

Measuring received signal quality

A method of enabling a communications receiver to verify an antenna weight previously signalled by the communications receiver to a base station, the method including the steps of; equalizing () a channel estimate of a dedicated pilot channel by the complex conjugate of a channel estimate of a common pilot channel to form an estimate of the transmission weight used by the base station; and for each transmission slot, combining () a component of the transmission weight estimates for current and previous slots to form an optimised transmission weight estimate.
