Cupertino, CA CID Page Clause Comment Proposed Change Resolution 5958 141.12 11.2.2.6 The use of PS-Poll frame together with the TWT power save mechanism could be clarified and justified. The should be used only with announced TWT. The TWT SP intiated by PS-Poll should be terminated like any TWT SP, i.e. no data should be transmitted outside of TWT SP. Please clarify how TWT and PS-Poll frames are used. It would make sense that if a PS-Poll frame is transmitted within the TWT SP and termiantion of the TWT SP also cancels the solicited DL PPDU transmission regardless if it has not been yet transmitted. Revise – agree in principle that TWT SP termination cancels also PS-Poll frames to wait for DL frame as response to the frame. Disagree with the principle that PS-poll frame needs to be transmitted within TWT SP. The frames to transition to active/power save mode and APSD trigger frame may be transmitted at any time.
