Abstract

Systems and methods are disclosed for optimizing the sounding interval in a MIMO communications system. Following a channel sounding protocol, net throughput may be estimated over time. The sounding interval may correspond to the period of time between the end of the sounding protocol and a time when the estimated net throughput is maximized. Estimating net throughput may involve estimating the number of bits that may be successfully transmitted divided by the time required to transmit. The number of bits that may be successfully transmitted may be estimated from a statistical channel profile including goodput.

First claim

What is claimed is:

1. A method for communication in a multiple input multiple output (MIMO) system comprising:
performing a channel sounding protocol during a first time period;
defining a plurality of bins beginning with a first bin and extending from an end of the first time period;
estimating net throughput during a second time period following the first time period by:
selecting a second bin, subsequent to the first bin;
summing bits that may be successfully transmitte…
