Abstract

The invention discloses a method, a device and a system for the forward link outer loop power control (FOLPC) of the high speed uplink packet access (HSUPA). The method comprises the following steps of: setting a sliding window buffer array, for setting the sliding window buffer array aiming at a same service, accounting the request failure indication of the hybrid automatic repeat request (HARQ)and the HARQ times aiming at all the links of the same service, and decision outputting according to the statistic of the buffer array; analyzing the enhanced dedicated transmission channel (DTCH) protocol frame, when the radio network controller (RNC) receives the enhanced dedicated transmission channel (DTCH) protocol frame transmitted by the base station; and controlling the output for controlling the output by judging the analyzing result according to the preset judge period, aiming at the different service types, and emptying the gliding window buffer array when outputs.

Description

technical field [0001] The invention relates to a method for high-speed uplink packet access in a third-generation mobile communication system, on a wireless network controller, to perform outer-loop power control for enhanced dedicated transmission channels under the condition of single-path or multi-path macro-diversity. Background technique [0002] After introducing the High Speed ​​Uplink Packet Access (HSUPA) service, an Enhanced Dedicated Transport Channel (EDCH) is added in the uplink. In E-DPDCH (Enhanced Dedicated Physical Data Channel) open-loop power control, the radio network controller (Radio Network Controller, RNC) needs to configure a reasonable reference power offset value, and according to a certain wireless quality feedback, dynamically Adjusting the transmission power on the DPDCH can satisfy the situation that the E-DCH channel changes in the wireless environment, and the power changes accordingly. [0003] In the uplink frame structure of HSUPA, chann...
