Abstract
Performing wireless transmission of data over a wireless communication medium. A first data structure may be maintained which includes data rate information for transmission using a first number of streams. A second data structure may be maintained which includes data rate information for transmission using a second number of streams. Channel characteristics of the wireless communication medium may be determined. Channel characteristic information may be maintained based on the determined channel characteristics. Accordingly, a stream configuration and data rate may be determined based on the current channel characteristic information. Wireless transmission may be performed using the determined stream configuration and data rate. Determining channel characteristics, maintaining current channel characteristic information, determining a stream configuration and data rate, and performing wireless transmission may be dynamically performed a plurality of times during wireless data transmission.
