wake-up radio (WUR) physical layer (PHY) protocol data unit (PPDU): A PPDU transmitted with the TXVECTOR parameter FORMAT equal to WUR. Abbreviations and acronyms TGba editor: Insert the following acronym definitions (maintaining alphabetical order): OOK on-off keying PCR primary connectivity radio TD type dependent WUR wake-up WURx wake-up receiver General description Components of the IEEE Std 802.11 architecture TGba editor: Insert a new subclause after subclause 4.3.15 as follows: Wake-up radio (WUR) STA The main PHY features in a WUR STA are the following: <Texts to be filled> The main MAC features in a WUR STA are the following: <Texts to be filled> A WUR non-AP STA can receive a wake-up frame from a WUR AP STA to trigger a transition of the corresponding primary connectivity radio to the awake state. Frame formats General requirements TGba editor: Change the paragraph as follows: The format of the MAC frames is specified in this clause. WUR frame format is defined in Subclause 9.10, and other MAC frame formats are defined in Subclauses 9.2 to 9.9. A STA shall be able to properly construct a subset of the frames specified in this clause for transmission and to decode a (potentially different) subset of the frames specified in this clause upon validation following reception. The particular subset of these frames that a STA constructs and decodes is determined by the functions supported by that particular STA. A STA shall be able to validate every received frame using the frame check sequence (FCS) and to interpret certain fields from the MAC headers of all frames. A STA shall transmit frames using only the frame formats described in Clause 9.
