Abstract

A base station forming part of a cellular communications system includes a reference signal generator, a boost selector and a transmitter. The reference signal generator provides a dedicated reference signal to be transmitted over plural antennas to a dedicated user device. The boost selector selects a dedicated boost level specific for the dedicated reference signal and the transmitter transmits the dedicated reference signal boosted by its dedicated boost level to the user device. A user equipment device includes a receiver, a boost determiner and a data demodulator. The receiver receives a dedicated reference signal transmitted by a base station where the dedicated reference signal has been boosted by a dedicated boost level specific to the user device. The boost determiner determines the dedicated boost level and the data demodulator demodulates a data signal from the base station using the dedicated boost level and a channel estimation value.
