2 doc.: IEEE 802.11-12/0070r1 January 2012 LG Electronics Inc. Submission Abstract This presentation provides –A method for fast association by using adaptive MCS in active scanning procedure Slide 2

3 doc.: IEEE 802.11-12/0070r1 January 2012 LG Electronics Inc. Submission Open-loop rate adaptation in WLAN Open-loop rate adaptation –MCS is adaptable to a variety of wireless channel environments –It requires no channel state information feedback General concept of open-loop rate adaptation in WLAN –In initial stage, the lowest code rate is applied to transmit frame –If previous transmission is successful, the code rate for the next transmission is increased –If previous transmission is failed, the code rate for the next transmission is reduced –Successful transmission can be reported by ACK frame or related response Slide 3

4 doc.: IEEE 802.11-12/0070r1 January 2012 LG Electronics Inc. Submission Association protocol in WLAN Active Scanning / Authentication / Association Protocol –It requires many management frames such as Probe Request/Response Authentication Request/Response Association Request/Response Slide 4 Inefficiency of association protocol –In the association stage, the lowest code rate is applied to frame transmission at first –The code rate is adjusted gradually according to the open-loop rate adaptation scheme –It makes the association procedure to be performed in low rate level, and it can give negative effect to the throughput in the association stage

5 doc.: IEEE 802.11-12/0070r1 January 2012 LG Electronics Inc. Submission Proposed link adaptation scheme Concept of the proposed idea –Link adaptation in scanning procedure Obtain channel information in scanning procedure Use appropriate MCS for frame transmission in association stage –Effect of the proposed link adaptation If appropriate MCS can be used from the association stage, faster association can be accomplished Slide 5

6 doc.: IEEE 802.11-12/0070r1 January 2012 LG Electronics Inc. Submission Proposed link adaptation scheme Proposed link adaptation in active scanning –STA transmits Probe Request frame and this frame acts as NDPA –NDP is transmitted after Probe Request frame –AP estimates the channel quality using NDP and decides the MCS index of the STA –The decided MCS index in transmitted by Probe Response frame as a feedback of NDPA –Apply the obtained MCS index for the next frame transmission Slide 6
