Problems solved by technology

[0006] However, the current method has a major disadvantage, that is, it may produce a ping-pong effect. When the environment changes greatly, the SNR value will be affected, and the data throughput will be unstable, so that it may increase suddenly. The phenomenon that needs to be reduced, the ping-pong effect is not a good phenomenon for data transmission, because it is easy to cause the loss of data packets

Embodiment Construction

[0031] In order to make those skilled in the art have a further cognition and understanding of the features, purposes and functions of the present invention, now in conjunction with the accompanying drawings, the detailed description is as follows:

[0032] The principle of the present invention is to properly adjust the data throughput by using the transmission power control information carried in the signal. In W-CDMA, both uplink (UL) and downlink (DL) data channels are divided into time slots and frames, and the length of one time slot is 666.667μsec, equivalent to the system The length of 2560 chips at the chip transmission rate, and fifteen time slots are concatenated into a 10ms frame. The frame is the basic unit of channel coding and data interleaving processing. However, some key information closely related to time, For example, the transmission power control bit will be added to each time slot, usually one bit of data, when the bit is "1", it means to increase the tr...

Abstract

The invention is a data throughput adjusting method, applied to adjusting data throughput in the wideband code division multiple access (WCDMA), including the following steps: A. providing many parameters, including: an upper limit power, a lower limit power, an increase parameter and a decrease parameter; B. receiving a signal; C. according to a piece of emission power control information controlling the signal emission power, searching a overstep power parameter and a non-full power parameter; D. judging if the non-full power parameter is greater than the increase parameter: if yes, increase data throughput and execute step G and if no, execute step E; E. judging if the overstep power parameter is greater than the decrease parameter: if yes, decrease data throughput and execute step G; if no, execute step F; F. keeping the data throughput, and execute step G; G. ending.

Description

technical field [0001] The present invention relates to a data throughput adjustment method, in particular to a data throughput adjustment method applied in Wideband Code Division Multiple Access (WCDMA). Background technique [0002] With the advancement of technology, mobile phones are becoming more and more popular, and people's requirements for mobile phones are getting higher and higher. In addition to basic voice communication functions, users also hope that mobile phones can have data transmission due to the popularity of the Internet. function. Of course, the requirements for data transmission speed are also getting higher and higher. [0003] In the same transmission environment, mobile phones that can provide higher transmission power can usually obtain higher transmission speed. However, the transmission power of mobile phones cannot be increased infinitely. Furthermore, excessively high transmit power can easily interfere with nearby users, forcing other users...
