Embodiment Construction

[0034] The core of the present invention is that in the ARQ system, the NodeB itself counts the data retransmission probability according to the received data information of the UE, and calculates and controls the uplink enhanced channel of the UE according to the statistical result and the working range of the retransmission probability configured by the RNC. Power offset, and send a corresponding power adjustment command to the UE according to the calculation result, and the UE changes the transmit power of the uplink enhanced channel according to the adjustment command, so that the retransmission probability converges to the best working range.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Those skilled in the art know that ARQ (Automatic Repeat Request) is a transmission mec...

Abstract

A method for regulating the signal emitting power of automatic retransmission request (ARQ) system includes such steps as configuring the working interval of retransmission probability, retransmission probability satistic by base station in each transmission interval, sending power regulating command to mobile station, and regulating the emitting power of up channel.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for adjusting and adjusting the transmission signal power of an automatic repeat request system. Background technique [0002] In data communication systems, ARQ (Automatic Repeat Request) technology is often used for error control. This technology adds a certain amount of redundant bits to the transmitted information to make it have a certain error detection capability. Error detection is performed on the received signal, and the error detection result is formed into a response signal and fed back to the sending end. According to the response signal, the sending end retransmits the set of information that the receiving end considers to be erroneous until the code group has no error codes. If the code group sent by the originator has both error correction and error detection capabilities, it is called HAQR (Hybrid Automatic Repeat Request). [0003] At present, i...
