  • Method and apparatus for maintaining desired link quality when no data is transmitted on transport channels having quality targets
    Patent number: 7215929
    Abstract: Disclosed is a mobile station executed method for updating a signal-to-interference ratio (SIR) target during a discontinuous transmission (DTX) period of a downlink transport channel having a network specified quality target value, as is a mobile station (100) that operates in accordance with the method. The method includes measuring a quality, such as the BLER, of another downlink transport channel for which a network (20) has not specified a quality target value; and updating the SIR target in accordance with the measured quality. For a case where the downlink transport channel for which the network has not specified a quality target value is on a power controlled physical channel, updating the SIR target uses the measured quality.
