ABSTRACT:
A link adaption method for multi input multi output (MIMO) system having a multi-antenna structure and a communicating method of MIMO stations in a basic service set (BSS), which constitutes a wireless communication network. The communicating method includes receiving from a predetermined MIMO station, the number of MIMO antennas and transmission rates supported by the respective MIMO stations. It further includes, storing one or more channel estimations indicators obtained while receiving various framed form the predetermined MIMO station for each MIMO antenna and for each transmission rate supported by the MIMO antenna, determining the threshold levels of the channel estimation for each MIMO antenna, and comparing the threshold levels with an average of channels estimation indicators for each MIMO antenna. The transmission rate is determined based on the comparison result and the data is then transmitted to the predetermined MIMO station ad the determined transmission rate.
