Method for determining reverse turn-on channel transmitting power in wireless communication system

Abstract

The invention relates to the method of detecting the reverse connecting channel beaming in the wireless communicating system. The invention mainly includes: firstly, the ahead seasonal quick real time broadcast message bears the weight of the reverse loading instance information; then, the connecting end gains the reverse load instance information from the said broadcast message, the corresponding reverse connecting channel delivering power can be adjusted and determined by the reverse loading instance, furthermore, the parameter needed by the connecting end adjusting arithmetic can be broadcasted through the system message. So the invention can adjust effectively the beaming power of the connecting channel according to the current real time reverse loading instance, for example, when the reverse load is heavier, the beaming power of the connecting channel can be added properly, in this way, the connecting speed and the succeeding rate can be improved, the power disturbing can be reduced. And, the invention adopts the existing key word of the broadcasting message to pass the parameter information needed by the invention, so the agility and the afterward compatibility can be assured.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for determining the transmission power of a reverse access channel in a wireless communication system. Background technique [0002] In a wireless mobile communication system, terminals usually send initial signaling or short messages through a reverse access channel. Since no two-way connection has been established between the terminal and the system before this, the terminal can only complete the power setting of the access channel and determine the reverse transmission power according to the open-loop power control. [0003] The open-loop power value depends on the path loss and reverse load of the forward link. If the reverse load is high, it should be accessed with a higher power to ensure the success rate of access and shorten the access delay; Conversely, if the reverse load is light, it can be accessed with less power without causing too much inte...

[0013] However, in the 1xEVDO protocol, the power setting value of the reverse access channel is only related to the fields in the forward AccessParameters message, and the update interval of this message is on the order of hundreds of time slots. Therefore, the reverse access channel The power setting value cannot quickly adapt to the reverse load change, which will inevitably cause access failure, delay or excessive interference, thus affecting the communication performance of the wireless communication system
