Title:
TRANSMISSION POWER CONTROL METHOD AND PORTABLE TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/050893
Kind Code:
A1
Abstract:
A control section (100) measures DPCH_RSCP and DPCH_ISCP of each path, and calculates DPCH_RSCP and DPCH_ISCP of each wireless link. Then, the control section (100) calculates the DPCH_SIR of each wireless link, and calculates difference between the DPCH_SIRs of the wireless links. When the calculated DPCH_SIR difference is smaller than a previously set DPCH_SIR difference threshold, received TPC data is discarded and the control section (100) does not execute transmission power control based on the TPC data. When the calculated DPCH_SIR difference is larger than the previously set DPCH_SIR difference threshold, the control section (100) executes transmission power control based on the TPC data for the wireless link having the larger DPCH_SIR.
