11n Partial Proposal:
Quantized Precoding with Feedback

Presented to the IEEE 802.11n Meeting, Berlin, Germany, September 2004.
This document describes the technical specification and FRCC compliance
report of „Quantized Precoding with Feedbackš for IEEE 802.11n as a partial
prospal. The proposed system is based on 802.11a and provides robust operating
modes with backward compatibility through the use of precoding based on limited
channel state information at the transmitter. The existing RTS/CTS mechanism is
used to inform the transmitter about the channel state. Quantizing the precoding
matrices using codebook of precoding matrices reduces the overall feedback
requirements. PHY and MAC enhancements are discussed.
