5959 Jarkko Kneckt 72.26 The Triggered TWT SP should define that AP shall transmit a Trigger frame or a frame with Reverse Direction Grant indication in the Triggered TWT SP. In both cases the AP schdules UL transmission resources for the STA. The transmission of the frame with Reverse Direction Grant is useful when data transmission is random or the AP does not have precise knowledge of the amount of UL data that a STA has or when few STAs wake up for the TWT SP. The Trigger frame and frame with RDG enables the AP to allocate transmission resource for the STA . When frame with RDG is transmitted, the transmission resources are not wasted, if the non-AP STA does not have traffic to transmit for the whole allocated resource. Please change the text p.72, l.26 to read:" includes Trigger frames or farmes with reverse direction The Trigger field is set to 1 to indicate that at least one Trigger frame or a frame with reverse direction grant is transmitted during the TWT SP." Reject – reverse direction does not promote efficient use of the medium that using a feature that is a fundamental enhancement offered by the TGax amendment. 6049 Jarkko Kneckt 73.03 How STAs that have established TWT Flow ID 1 or 2 transmit UL DATA? The recommendations do not allow UL data transmission. Please allow UL and DL data frames transmission at the end of the TWT SP. Thus, the first part of the TWT may be used to exchange short signaling packets and the last part could be used for the data transmissions. Transmitting data in the same TWT SP simplifies the TWT handling. Reject – see ID value 3, which already has no restrictions on what may be transmitted during the SP – this is all within the control of the AP and is therefore an implementation decision with all options available as per the current encodings in the draft specification. 0 0
