Abstract: A method of operating a wireless local area network (WLAN) system is provided. The WLAN includes an access point supporting uplink multiple user multiple input multiple output mode. The method of operating the WLAN system includes selecting a first station, receiving channel information from the selected first station by a second station, calculating a SNR reduction value based on the channel information by the second station, and selecting the second station based on the SNR reduction value.

Abstract: A method of controlling a data rate by a transmitting device in a wireless communication system and the transmitting device are provided. The method includes detecting a condition to change a current data rate; performing a probing process based on a bandwidth and a Modulation and Coding Scheme (MCS); and controlling the data rate based on a result of the probing process. The transmitting device includes a controller configured to detect a condition to change a current data rate; and a transmitter and a receiver configured to perform a probing process based on a bandwidth and an MCS, wherein the controller is further configured to control a data rate based on a result of the probing process.
