2. Resolution to comment 520 i. e
Resolution to comment 520 i.e. “SINR and SNIR shall be replaced with LQI as a generic metric”

3. Resolution Modified the following paragraph in 7.4.27 in pp 34
“The Best Sector field shall be set to the index of the best transmit sector for the originating DEV. In the SAS case, this also represents the index of the best receiver sectors for the target DEV.
The Best Sector SINR field shall be set to the value of SINR measured by the Target DEV for the best sector. The Best Sector SINR field encoded in dB with a value of zero indicating an SINR less than or equal to 0 dB and a value of fifteen indicating an SINR of greater than or equal to 15 dB
The Second Best Sectors field shall be set to the index of the second best transmit sector for the originating DEV. In the SAS case, this also represents the index of the second best receiver sectors for the target DEV
The Second Best Sector SINR field shall be set to the value of SINR measured by the Target DEV for the second best sector. The Second Best Sector SINR is encoded in the same manner as the Best Sector SINR.”
To the paragraph in the next page.

4. Resolution (cont’d)
Modified the following paragraph in in pp 34
“The LQI type field indicates the type of metric used in Best/Second Best Sector LQI. The field value to a certain type is defined in Table xxx.
The Best Sector field shall be set to the index of the best transmit sector for the originating DEV. In the SAS case, this also represents the index of the best receiver sectors for the target DEV.
The Best Sector SINR LQI field shall be set to the value of SINR LQI measured by the Target DEV for the best sector. The Best Sector SINR LQI field is encoded in dB with 2dB step. A value of zero indicating an SINR LQI less than or equal to 0 dB and a value of fifteen indicating an SINR LQI of greater than or equal to dB. The corresponding LQI values in the case of SNR/SINR and RSSIr are given in Table abc and Table xyz.
The Second Best Sectors field shall be set to the index of the second best transmit sector for the originating DEV. In the SAS case, this also represents the index of the second best receiver sectors for the target DEV
The Second Best Sector SINR LQI field shall be set to the value of SINR LQI measured by the Target DEV for the second best sector. The Second Best Sector SINR LQI is encoded in the same manner as the Best Sector SINR LQI .”

5. Resolution (cont’d) Change the Figure 48m in page 34 from to
Add text to , pp 34 in line 10 as
The LQI Type field shall be set in accordance to the metrics used as shown in Figure 48x Table xxx
