Abstract: A sounding method utilized for a wireless communication system is disclosed. The wireless communication system comprises a base station and a plurality of stations, and the plurality of stations are divided into a plurality of groups. The sounding method comprising receiving a first sounding request from a first group of the plurality of groups; determining whether the first sounding request is granted for performing sounding after receiving the first sounding request; determining an initial sounding instant for the first group when the first sounding request is granted; and performing sounding of the first group starting at the initial sounding instant when the first sounding request is granted.

Abstract: The method of dynamically adjusting frame aggregation size for a first communication device receiving aggregation packets from a second communication device in a wireless communication system is disclosed. The method comprises monitoring a buffered data size of the first communication device, and notifying the second communication device of a capable buffer size of the first communication device when the buffered data size monitored by the first communication device is higher than a threshold.
