Table 9248l – TWT Setup Command field values TWT Setup field value Command name Description when transmitted by a TWT requesting STA Description when transmitted by a TWT responding STA Description when transmitted by a TWT scheduled STA Description when transmitted by a TWT scheduling STA 0 Request TWT The Target Wake Time field of the TWT element contains 0s as the TWT responding STA specifies the target wake time value for this case, other TWT parameters* are suggested by the TWT requesting STA in the TWT request. N/A The Target Wake Time field of the TWT element contains 0s as the TWT scheduling STA specifies the target wake time value for this case, other TWT parameters* are suggested by the TWT scheduled STA in the TWT request. N/A 1 Suggest TWT TWT requesting STA includes a set of TWT parameters such that if the requested target wake time value and/or other TWT parameters cannot be accommodate, then the TWT setup might still be accepted. N/A N/A 2 Demand TWT TWT requesting STA includes a set of TWT parameters such that if the requested target wake time value and/or other TWT parameters cannot be accommodate, then the TWT setup will be rejected. N/A N/A 3 TWT Grouping N/A N/A N/A 4 Accept TWT N/A TWT responding STA accepts the TWT request with the TWT parameters* indicated in the TWT element transmitted by the responding STA. N/A TWT scheduling STA accepts the TWT request with the TWT parameters* indicated in the TWT element transmtted by the TWT scheduled STA. 5 Alternate TWT N/A TWT responding STA suggests TWT parameters that are N/A N/A
(To be added) BSS_COLOR FORMAT is HE_SU or HE_MU or HE_EXT_SU or HE_TRIG. Set to a value of the AP’s choosing within the range 0 to TBD (see 25.11 (STA ID, Uplink Flag and BSS Color in HE PPDUs)). Y Y Otherwise Not present N N UPLINK_FLAG FORMAT is HE_SU or HE_MU or HE_EXT_SU Set to 1 if the HE PPDU is addressed to an AP Set to 0 otherwise (see 25.11 (STA ID, Uplink Flag and BSS Color in HE PPDUs)). Y Y Otherwise Not present N N STA_ID_LIST FORMAT is Indicates the list of STA IDs for an HE MU PPDU (see 25.11 (STA ID, Uplink Flag and BSS Color in HE PPDUs)). Y Otherwise Not present N N NOTE 1—In the “TXVECTOR” and “RXVECTOR” columns, the following apply: Y = Present; N = Not present; O = Optional; MU indicates that the parameter is present once for an HE SU PPDU, HE extended range SU PPDU and HE trigger-based PPDU and present per user for an HE MU PPDU. Parameters specified to be present per user are conceptually supplied as an array of values indexed by u, where u takes values 0 to NUM_USERS-1. HE PHY Introduction HE PPDU formats Four HE PPDU formats are defined: HE SU PPDU, HE MU PPDU, HE extended range SU PPDU and HE trigger-based PPDU. The format of the HE SU PPDU is defined as in Figure 261. This PPDU is used for SU transmission and in this format the HE-SIG-A field is not repeated.
