Re: [STDS-802-11-TGBN] TGbn PHY Motion Request

Hi Alfred,

 

Please add the followings to the TGbn PHY motion list:

 

Motion 1: Move to include the following text to the 11bn SFD: (DCN# 11-24/1510r2)

·       11bn supports the following DBW dependent DRU size support to maximize BW and power efficiency

    • No MRU in distributed transmission
    • 20MHz: RU26, RU52, RU106
    • 40MHz: RU26, RU52, RU106, RU242
    • 80MHz: RU52, RU106, RU242, RU484

Passed without any objection 

 

Motion 2: Move to include the following text to the 11bn SFD: (DCN# 11-24/1510r2)

·       11bn supports per 80MHz DRU/RRU switch if PPDU BW >80MHz and no hybrid DRU and RRU mode for up to 80MHz

Passed without any objection 

 

Motion 3: Move to include the following text to the 11bn SFD: (DCN# 11-24/1510r2)

·       In mixed RRU and DRU transmission the RRU LTF follows the exact same rule as if there is no DRU. The DRU LTF sequence depends on the distribution BW

Passed without any objection 

 

Motion 4: Move to include the following text to the 11bn SFD: (DCN# 11-24/1510r2)

 

  • DRU transmission uses single stream pilots in both LTF and data portion

Passed without any objection 

Motion 5: Move to include the following text to the 11bn SFD: (DCN# 11-24/1510r2)

  • DRU only uses 4x LTF

Passed without any objection 

 

Motion 6: Move to include the following text to the 11bn SFD: (DCN# 11-24/1510r2)

 

  • In DRU transmission, global CSD provides CSD start index i for each DRU. If Nss for this DRU is larger than 1, then it will use CSD[mod(i: i+Nss-1, 8)] for each ss
