Abstract: Methods and apparatus for protection of multi-user (MU) transmission are described herein. An apparatus includes a receiver, a transmitter and a processor. The receiver and the processor detect a trigger frame for an uplink (UL) multi-user (MU) transmission. The processor and the transmitter generate and send a frame in response to the trigger frame and transmit channel availability information for a plurality of channels in response to the trigger frame. The receiver and the processor detect data in a resource unit (RU) of a downlink (DL) MU physical layer (PHY) protocol data unit (PPDU) on one of the plurality of channels. The one of the plurality of channels is based on the transmitted channel availability information.

Abstract: Methods and apparatus for channel estimation and precoding based analog channel state information feedback are described. A method, implemented in a network node, includes receiving, from another network node, a sounding frame with a reference sequence that is known to the network node. At least one channel state information (CSI) matrix is estimated using the received sounding frame and the reference sequence to generate at least one estimated CSI matrix, and the at least one generated estimated CSI matrix is applied as at least one precoded estimated CSI matrix to a feedback packet. The feedback packet is sent to the other network node and includes at least one training field carrying the at least one precoded estimated CSI matrix and at least one training field that carries CSI information that is not precoded.
