UNIFORM WLAN MULTI-AP PHYSICAL LAYER METHODS

摘要

A method and apparatus are disclosed for training and feedback in sectorized transmissions. An IEEE 802.11 station may receive a Sector Training Announcement frame from an AP. The station may then receive a plurality of Training frames from the AP, wherein each of the plurality of Training frames is separated by a short interframe space (SIFS) and each of the plurality of Training frames is received using a different sectorized antenna pattern. The station may generate a Sector Feedback frame indicating a sector based on the plurality of Training frames. The station may send the Sector Feedback frame to the AP. The Sector Feedback frame may indicate a desire to enroll in sectorized transmissions. Alternatively, the Sector Feedback frame may indicate a desire to change sectors.
