Hi Alfred,

Please add the following two motions to the PHY motions queue:

  1. Move to add the following rules for Co-BF in the TGbn spec in 37.15.2.1.4 Co-BF transmission procedure?

         If the minimum number of data OFDM symbols of the Co-BF transmission indicated in the Co-BF Invite frame corresponds to Navbits > 3888 bits for a user of the coordinated AP, then the coordinated AP may indicate that 2xLDPC will be used for the user in the Co-BF Response frame.

         If the minimum number of data OFDM symbols of the Co-BF transmission indicated in the Co-BF Invite frame corresponds to Navbits ≤ 3888 bits for a user of the coordinated AP, then the coordinated AP shall not indicate that 2xLDPC will be used for the user in the Co-BF Response frame.

         A coordinating AP shall not choose a value for the Length field in the L-SIG field of the Co-BF PPDU in the Co-BF Trigger frame that corresponds to a number of OFDM symbols in the Data field which is smaller than the minimum number of data OFDM symbols the coordinating AP had indicated in the Co-BF Invite frame

                Note: These changes for the TGbn editor are reflected in the word document below

                https://mentor.ieee.org/802.11/dcn/25/11-25-1670-00-00bn-2x-ldpc-related-spec-text-changes-for-cobf.docx

               Supporting documents: 11-25/1609r2 and 11-25/1670r0

               SP result:  Passed unanimously

 

  1. Move to add the following recommendation for Co-BF to the TGbn spec in 37.15.2.1.4 Co-BF transmission procedure?

         To help the coordinated AP choose an appropriate LDPC codeword length, the minimum number of data OFDM symbols of the Co-BF transmission indicated in the Co-BF Invite frame should be greater than or equal to 0.5 times the maximum number of data OFDM symbols of the Co-BF transmission indicated in the Co-BF Invite frame.

                Note: These changes for the TGbn editor are reflected in word document below

                https://mentor.ieee.org/802.11/dcn/25/11-25-1670-00-00bn-2x-ldpc-related-spec-text-changes-for-cobf.docx

                Supporting documents: 11-25/1609r2 and 11-25/1670r0

                SP result:  Passed unanimously

Thanks,

Sameer
