Techniques for explicit feedback delay measurement

摘要

Techniques for explicit feedback delay measurement are described. An apparatus may comprise a processor to generate a steering matrix for transmit spatial processing over a channel, determine a delay time associated with explicit feedback information for the channel, and determine whether to modify the steering matrix with the explicit feedback information based on the delay time. Other embodiments are described and claimed.

1. A wireless device, comprising:
circuitry to calculate a beamforming feedback matrix for a beamformer, the circuitry to determine a time delay between a feedback request sent to a beamformee and a feedback response received from the beamformee over a multi-carrier communications channel of a wireless local area network (WLAN), the feedback response to include information to calculate the beamforming feedback matrix for transmit beamforming, the circuitry to determine whether to use the information in the feedback response to calculate the beamforming feedback matrix based on the time delay.
