Interpretation of a Motion to Adopt

A motion to adopt the changes defined in this submission means that the editing instructions and any changed or added material are actioned in the TGn Draft. This introduction, and OMnnn headings are not part of the adopted material.

Editing instructions formatted like this are intended to be copied into the TGn Draft (i.e. they are instructions to the 802.11 editor on how to merge the TGn amendment with the baseline documents).

TGn Editor: Editing instructions preceded by “TGn Editor” are instructions to the TGn editor to modify existing material in the TGn draft. As a result of adopting the changes, the TGn editor will execute the instructions rather than copy them to the TGn Draft.

OM149

9.18.1.1.2 Up Link Transmissions

Insert the following text at the end of Section 9.18.1.1.2:

The AP may gain control of the channel whenever the channel remains idle for a PIFS time from the start of an ULT duration. The AP may transmit the PSMP-recovery frame, which is same as the original PSMP frame with modified STA info fields, to boost the reliability of the PSMP sequence. PSMP-recovery frame carries modified ULTs (and/or DLTs) for the currently scheduled STA and other STA(s) scheduled later in the current PSMP sequence. The modified ULT (or DLT) Start Offset is specified relative to the end of the PSMP-recovery frame. The ULT Duration field of the currently scheduled STA is modified as the remaining ULT time allowed for the STA after the PSMP-recovery time. The ULT (or DLT) Duration fields of other scheduled STAs remain unchanged.
