Problems solved by technology

[0007] It can be seen that the existing method of controlling the transmission power of E-HICH mainly refers to the power of other channels in the same time slot as E-HICH, but in actual situations, it cannot be guaranteed that E-HICH and other channels always in the same time slot

Embodiment 1

[0059] The methods described in Embodiment 1, Embodiment 2 and Embodiment 3 are all described by taking the adjustment of the power gain factor of the feedback information of a certain UE as an example. In practical applications, the NodeB can adjust the power gain factor according to the above method. The power gain factor of each feedback information is multiplexed on the same E-HICH, that is, the transmission power of each feedback information is adjusted, so as to control the power of the E-HICH and achieve the purpose of the present invention.

[0060] When performing power adjustment on multiple feedback information multiplexed on the same E-HICH, the mutual interference among the feedback information should also be taken into consideration. When the number of feedback information multiplexed on the same E-HICH is relatively large, the mutual interference between feedback information will be more serious; when the number of feedback information multiplexed on the same E-H...

Abstract

The invention discloses a power control method and device for controlling power of a retransmitting confirmation indication channel in high-speed uplink packet access. The method comprises the steps of: respectively counting frequency of transmission faults of feedback information on an E-HICH (Enhanced-Hybrid Indication Channel) and comparing the frequency with a preset value, and counting transmission block error rate on an E-PUCH (Enhanced-Physical Uplink Channel) of UE (User Equipment) corresponding to each feedback information, comparing smoothened transmission block error rate with a preset block error rate to obtain a power gain factor increment and a second power gain factor increment of each feedback information; respectively weighting the first power gain factor increment and the second power gain factor increment and summating; and regulating the power gain factor of each feedback information according to the summated value. The power gain factor of the feedback information multiplexed on the E-HICH is regulated through controlling the E-PUCH, thus the sending power of the feedback information is regulated, and the purpose of controlling the power of the E-HICH is realized.

Description

technical field [0001] The present invention relates to High Speed ​​Uplink Package Access (HSUPA, High Speed ​​Uplink Package Access) technology, in particular to an enhanced dedicated channel hybrid automatic retransmission acknowledgment indicator channel (E-HICH, E-DCH HARQ Acknowledgment Indicator Channel) power in HSUPA Control method and device. Background technique [0002] In order to improve the throughput of network data transmission, improve cell coverage, and reduce data transmission delay, time division duplex (TDD) system introduces HSUPA technology. When using HSUPA technology to transmit data, the process is as follows: figure 1 shown. In step 101, a base station (NodeB) sends resource scheduling information to a user equipment (UE, User Equipment) through a downlink absolute grant channel (E-AGCH, Enhanced Uplink Absolute Grant Channel). In step 102, the UE sends data to the NodeB through an uplink physical channel (E-PUCH, Enhanced Uplink Physical Chann...
