A method of performing dynamic sounding in a wireless communication device includes determining whether to perform sounding based on an age of current channel state information (CSI). An achievable throughput can be recorded as a reference throughput after performing the sounding. A current achievable throughput can be compared with the reference throughput. A CSI timestamp can be reset when the current throughput is above the reference throughput by a first predetermined amount, thereby prolonging a lifespan of the current CSI. The CSI timestamp can be reduced when the current throughput is below the reference throughput by a second predetermined amount, thereby reducing the lifespan of the current CSI.
