    Abstract: Certain aspects of the present disclosure relate to a low-overhead method for communicating Channel State Information (CSI) feedback in Very High Throughput (VHT) wireless communications systems. The present disclosure also provides packet formats for Null Data Packet Announcement (NDPA), CSI Poll and CSI feedback. In some cases, the CSI feedback may be too large to be carried in a single Media Access Control (MAC) protocol data unit (MPDU) or a Physical Layer (PHY) protocol data unit (PPDU), and a proposed protocol for CSI feedback segmentation can be then utilized.

    Abstract: Systems, methods, and devices for communicating a compressed beacon are described herein. In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.
