METHOD AND SYSTEM FOR DUAL-MODE (SINGLE-USER AND MULTI-USER) PACKET ERROR RATE BASED RATE CONTROL IN WIRELESS COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method of performing dual-mode rate control for an access point in a wireless communication system, including a single-user mode and a multi-user mode of operation.SOLUTION: In the single-user mode, a basic rate for a station is determined based on channel conditions. In the multi-user mode, a rate for a plurality of stations is determined using tracking. The tracking includes performing a sounding for the plurality of stations. An initial multi-user current rate is then set equal to a function of the number of users and the basic rate. A transmission is sent to the plurality of stations using the current rate. A packet error rate (PER) is detected during transmission to the plurality of stations. The current rate is adjusted based on the PER. After rate adjustment, either sounding is triggered or the method returns to sending a transmission using the current rate.SELECTED DRAWING: Figure 3
