A method for transmitting packets. The method includes making a first determination, using a first relevant sample set for a first client device, that the first client device does not need to be sounded and making a second determination, using a second relevant sample set for the second client device, that a second client device needs to be sounded. The method further includes, based on the first and second determination, performing a sounding operation for the second client device to obtain channel state information for the second client device and after performing the sounding operation for the second client device: wirelessly transmitting at least one packet to the first client device using historical channel state information for the first client device, and wirelessly transmitting at least one packet to the second client device using the channel state information.

Method and system for reducing sounding overhead in wireless communication

A method for transmitting data from a sender to a receiver over a channel. The method includes identifying the receiver, obtaining an initiation correlated symbol sequence (CSS) associated with the receiver, transmitting the initiation CSS, where the sender and the receiver are configured to communicate over the channel, where the channel is a frequency band in a radio-frequency spectrum. The method further includes receiving a first reservation CSS from the receiver signaling that the receiver has reserved the channel in order to receive the data from the sender. In response to receiving the first reservation CSS, transmitting the data to the receiver, and receiving an acknowledgment CSS from the receiver signaling that the receiver has received the data from the sender.
