Abstract
When an HSDPA and an Enhanced Uplink are applied, a dedicated physical channel, a high speed dedicated physical control channel, and an enhanced dedicated physical control channel are made to follow only a TPC bit of a serving cell; and when a received power of an enhanced dedicated physical data channel is large, a non-serving cell instructs a mobile station UE to reduce the transmission rate of the enhanced dedicated physical data channel so that an interference power from an adjacent cell in an uplink is controlled while communication quality in a downlink is prevented from deteriorating.
