    Abstract: Systems, methods, and devices for acknowledging communications from a plurality of wireless devices in a wireless network are described herein. In some embodiments, an access point for the wireless network transmits a group acknowledgment (ACK) to indicate whether communications (packets) from the plurality of wireless devices have been received or correctly decoded within some time interval. Each wireless device may have a different time interval associated with it. For some embodiments, the time interval for a wireless device is relative to when a previous group ACK was sent. A group ACK may include a bitmap. In some embodiments, the bitmap indicating whether a communication has been received or correctly decoded may be transmitted as part of a beacon.

    Abstract: In a downlink multi-user multiple input multiple output (DL MU-MIMO) system, channel state information (CSI) feedback duration may strongly affect media access control (MAC) efficiency. While a time domain compression may give a significant reduction in feedback duration, the time domain compression may have complexity issues at the station (STA). In particular, for time domain compression, a large complex matrix multiplication may be required at the client to estimate a cyclic prefix (CP) length impulse response, which best models the frequency response of the channel. Embodiments of the invention comprise a hybrid scheme that may reduce the above complexity while maintaining significant compression gains.
