Abstract: A method including communicating by an apparatus with base stations using a high speed uplink packet transmission technique that provides the apparatus with serving and non-serving links to base stations as well as scheduled transmissions in a serving link. A transmission power downgrading command is detected at the apparatus from a non-serving link. In a situation in which no scheduled transmission took place by the apparatus during preceding transmission period, the downgrading command is prevented from causing the apparatus to start applying a lowest value of a variable or parameter that defines the transmission power or power ratio for scheduled transmission.
