FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication. Certain aspects of the present disclosure relate to a low-overhead method for transmitting channel state information (CSI) feedback in very high throughput (VHT) wireless communication systems. The present disclosure also provides packet formats for null data packet announcement (NDPA), CSI Poll and CSI feedback.
EFFECT: using the disclosed protocol for CSI feedback segmentation in order to transmit media access control (MAC) protocol data unit (MPDU) or a physical layer (PHY) protocol data unit (PPDU).
