Re: [STDS-802-11-TGBN] Motion request

Hi Alfred,

 

Can you please add the following motion on CTDMA/TXOP sharing to the TGbn agenda for voting?

 

 

Do you agree that:

  • The maximum time allocated by a sharing AP in a TXOP to all shared AP for CTDMA is not larger than the TXOP limit it advertised for the minimum between AC_VI TxOP limit and the TxOP Limit of the AC it obtains the TxOP with to its associated STAs.
    • If TXOP limit for an AC is 0, there is no CTDMA in a TXOP obtained using that AC.
  • The sharing AP shall use at least a TBD portion of the obtained TXOP for data communication with its own associated STAs.

Note: similar consideration will apply for TXS mode 2

 

Supporting List: [24/0093]

 

SP result in MAC ad-hoc: unanimous.

 

Regards,

Dibakar

Hi Alfred,

Could you please queue the following motion on CTDMA/TXOP sharing to the TGbn agenda for voting?: 

Do you agree to define a mechanism as part of the procedure of time sharing during a TXOP (e.g. C-TDMA, TXS, …) to support fairness to neighboring STAs (APs and non-APs)?

  • Exact mechanism is TBD
  • Supporting documents: 11-24-93, 11-25-86r0

SP Result: (don’t recall) think it was 144Y/27N

Regards,

Dibakar

Dear Alfred,

Could you please queue the following motion on P EDCA to the TGbn agenda for voting?: 

[M1] Do you agree to define HIP EDCA in UHR where a STA with Low Latency traffic may be allowed, based on TBD conditions, to send a Defer Signal (it is TBD whether CTS or RTS is used) to start a protected short contention for pending LL data

  • Conditions to be allowed to send a Defer Signal is TBD
  • STA in HiP EDCA always use RTS/CTS as initial frame exchange and retry.
  • Duration of protected short contention is TBD.
  • Access parameters (AIFSN, CW and the expansion rules) used to transmit the Defer Signal are TBD. The retry count where the Defer Signal is allowed to be sent is TBD
  • Contention parameters for the protected short contention are TBD. The STAs that transmitted a Defer Signal but did not win the protected short contention will initiate a new retry.
  • Low Latency traffic is treated as AC_VO traffic. Other cases are TBD.
  • The solution would provide control on the degree of collisions that may occur while using it and, allows for autonomous randomness or/and controlled by the AP      
  • No new mandatory synchronization requirement on STA side
  • HIP EDCA is used by the STAs in a BSS only when this feature is enabled by the AP

Supporting doc: 24/1144r1

SP Result: 150Y, 14N, 70A
