Abstract
Immediately before transmitting a packet signal, a packet transmission base station (BS) increases a target ISR of UL DPCH (S), increases the TPC transmission power transmitted by the DPCH (S), increases a power balancing reference power, and increases a DL DPCH transmission power (S). In a mobile station (MS), during packet reception, only a packet transmission base station () controls the UL DPCH transmission power (S). This improves the reception quality at the base station () of HS-DPCCH including ACK/NACK and reduces the error ratio of the ACK/NACK signal.
