摘要： A method aggregates frames to be transmitted over a channel in a wireless network into a single frame. Multiple MSDU frames having identical destination addresses and identical traffic classes, received in the media access control layer from the logical link layer in a transmitting station are aggregated into a single aggregate MPDU frame, which can be transmitted on the channel to a receiving station. In addition, aggregate MSDU frames with different destination addresses and different traffic classes received from the media access control layer can be further aggregated into a single aggregate PPDU frame before transmission.

摘要： A method transmits transmitting training frames in a MIMO system. A long sequence of training frames is transmitted from a station B to a station A via a channel of the MIMO system, in which the station A includes NA antennas and N—SS RF chains and the station B includes NB antennas and NB—SS RF chains, and a number of frames in the long sequence of training frames is at least equal to A short sequence of training frames is transmitted from the station A to the station B via the channel in response to receiving the long sequence of training frames. A number of frames in the short training sequence is at least equal to
