Patent Searching and Data


Title:
移動通信システムにおける送信電力制御装置
Document Type and Number:
Japanese Patent JP4447281
Kind Code:
B2
Abstract:
A transmission power control apparatus adapted to control a reference Signal-power-to-Interference-power Ratio (SIR) value for controlling a transmission power of a mobile terminal equipment based on a reception quality of a plurality of radio access bearers (RAB) at a base station apparatus (Node-B), with respect to a physical channel to which the plurality of radio access bearers are mapped, when making a radio connection between the mobile terminal equipment and the base station apparatus in a mobile communication system, characterized by comprising: calculating means for calculating an increase or decrease value (”SIR) of the reference SIR value for an inner loop transmission power control based on reception quality information; updating means for updating a reference value (SIR_before) of the reference SIR value when adding or deleting a radio access bearer; adding means for adding the increase or decrease value (”SIR) to the reference value (SIR_before) of the reference SIR value; and notifying means for notifying an added value (SIR_before+”SIR) of the reference value and the increase or decrease value to the base station apparatus as a set value of the reference SIR value, wherein a transmission power control is carried out by setting the reference SIR value based on an updated reference value when adding or deleting the radio access bearer.
