Channel estimation for phase-only feedback and methods for use therewith

摘要

An apparatus includes a receiver to receive a first signal from at least one additional apparatus including a data frame including a FACK request in a signal (SIG) field. A baseband processor generates feedback information for use to perform channel estimation. A transmitter transmits a second signal that includes the feedback information to the at least one additional apparatus.

主权项

1. An apparatus, comprising:
a receiver to receive a first signal from at least one additional apparatus including a data frame formatted in accordance with an Institute of Electrical and Electronic Engineers (IEEE) 802.11 standard, the data frame including a request for phase-aligned space time block coding (STBC) phase feedback included in an 802.11 signal (SIG) field of the data frame, wherein the data frame is a single data frame; a baseband processor, coupled to the receiver, generates phase feedback information based on a channel estimation of a wireless communication channel between the apparatus and the at least one additional apparatus, wherein the baseband processor generates the channel estimation from an analysis of the single data frame; and a transmitter, coupled to the baseband processor, transmits an acknowledgement (ACK) frame to the at least one additional apparatus in response to the data frame, wherein the ACK frame includes the phase feedback information.
