Problems solved by technology

[0004] Statistics-based methods include ARF, AMAF, SampleRate, Onoe, AMRR and other algorithms, but these algorithms will cause the transmission rate to drop too fast due to signal interference, and when the signal interference ends, the transmission rate will not be reduced. slowly rise
[0005] In view of the previous algorithm, the transmission rate often drops too fast, and after the interference ends, the transmission rate cannot increase quickly
Therefore, the previous algorithm cannot quickly and dynamically adjust the transmission rate, resulting in a decrease in throughput

Embodiment Construction

[0020] Please refer to this invention figure 1 , providing a wireless adaptive rate control method, comprising the following steps:

[0021] Step S110: The wireless base station transmits a plurality of first sounding frames to the UE at a first transmission rate.

[0022] Step S112: The wireless base station calculates a first packet loss rate of the probing frames transmitted to the UE.

[0023] Step S114: The wireless base station calculates a first throughput according to the first transmission rate and the first packet loss rate.

[0024] Step S116: The wireless base station adjusts the first transmission rate by comparing the difference between the first throughput and a preset value.

[0025] Wherein, the wireless base station transmits a plurality of detection frames to the user end equipment, and the user end equipment may be a workstation. When the wireless driver is in automatic mode, the wireless base station will perform a detection frame at a rate higher than ...

Abstract

The invention discloses a wireless adaptive rate control method. The method comprises steps: a wireless base station transmits multiple first detection information frameworks to customer premise equipment at a first transmission rate; the wireless base station calculates a first packet loss rate when the detection information frameworks are transmitted to the customer premise equipment; the wireless base station calculates a first throughput according to the first transmission rate and the first packet loss rate; and the wireless base station compares the difference between the first throughput and the preset value to adjust the first transmission rate.

Description

technical field [0001] The present invention relates to a rate control method, in particular to a wireless adaptive rate control method. Background technique [0002] The transmission environment of a general communication system, especially a wireless communication system, is constantly changing due to various external factors (such as climate and noise, etc.), so the transmission rate initially set by the communication system may not meet the subsequent transmission environment. If the changed transmission environment can accept a transmission rate higher than the initial transmission rate, the communication system wastes available transmission resources. Conversely, if the changed transmission environment cannot accept a transmission rate higher than the initial transmission rate, the throughput of the communication system will drop significantly. Therefore, it is necessary to timely adjust the transmission rate of the communication system according to the changing trans...
