3 POWER CONTROL OF DOWNLINK SHARED CHANNEL IN SOFT HANDOVER IN 3GPP SYSTEM

摘要

According to the present invention, a dedicated CHannel (DCH) associated with a Downlink Shared CHannel (DSCH) in a 3GPP system may improve performance of a DSCH by performing separate power control on a TFCI field for a DSCH during a soft handover. The present invention relates to a power control method.;In the present invention, in performing power control of the TFCI bit for the DSCH in the 3GPP system, the mobile station assigns different power control schemes to the TFCI bit according to a mode selected by a user equipment (UE). By measuring the power from the base station of the base station to set the largest base station as the primary (primary) base station, when the base station to which the DSCH is selected as the primary base station transmit power by a TPC command (Transmitt Power Control) such as DCH The present invention relates to a power control method of a TFCI field for a DSCH channel during handover of a 3GPP system, characterized in that, when the base station to which the DSCH is transmitted is not the main base station, power control is performed by transmitting with a constant power.
