Document Type and Number:
Japanese Patent JP4343247
Kind Code:
B2
Abstract:
When a mobile station transmitting a plurality of channels having different transmission timings such as a DPDCH and a HS-DPCCH in uplink measures transmission power over a transmission power measurement period with a slot of the DPDCH as a reference, the transmission timing difference between the channels affects the accuracy of the transmission power measurement. In the present invention, therefore, a transmission power measurement period is changed depending on transmission timings of the uplink channels such as the DPDCH and the HS-DPCCH, the presence or absence of the HS-DPCCH in addition to the DPDCH, or specifications (version) of the standard applied to the mobile station.
