Abstract: Various schemes pertaining to coordinated time-division multiple-access (C-TDMA) protocols, transmission opportunity (TXOP) sharing modes for time allocation, and exchange of parameters in multi-access point (multi-AP) systems are described. An apparatus (e.g., a sharing access point (AP)) acquires a TXOP. The apparatus also triggers one or more shared APs to participate in C-TDMA communications with respectively associated stations (STAs) within the TXOP.

Abstract: A Wi-Fi communication method includes: performing resource allocation for multi-user transmission orthogonal frequency division multiple access (OFDMA) according to a regulated frequency band boundary and a resource unit (RU) type, and sending information indicative of the resource allocation, where the RU type includes at least one of regular RU (rRU) and distributed-tone RU (dRU), the resource allocation indicates RUs or multiple RUs (MRUs) allocated in a channel, the channel is across the regulated frequency band boundary, and an RU or MRU allocated per user in the channel is not across the regulated frequency band boundary when using rRU.

Abstract: Techniques pertaining to efficient and flexible frequency domain (FD) aggregated physical-layer protocol data unit (FD-A-PPDU) with the same and/or mixed WiFi generations transmission are described. An apparatus (e.g., a station (STA)) performs a wireless communication by: (i) transmitting a FD-A-PPDU or (ii) receiving the FD-A-PPDU. The wireless communication is performed in a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz bandwidth with 80 MHz being a minimum size of each of multiple PPDUs of the FD-A-PPDU. The FD-A-PPDU may be a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz FD-A-PPDU. The FD-A-PPDU may include PPDUs having a same PPDU format or different PPDU formats of different WiFi generations and utilizing a minimum size of 80 MHz non-overlapping frequency subblocks as a base building block.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a station (STA). In certain configurations, the STA transmits a request-to-send (RTS) frame in an enhanced long range (ELR) format for obtaining a transmission opportunity (TXOP). The STA receives a first clear-to-send (CTS) frame in the ELR format or a non-ELR format responding to the RTS frame. In response to receiving the first CTS frame, the STA transmits data in the ELR format in the TXOP. In certain configurations, the STA further receives an acknowledgement in the same format as the first CTS frame for responding to the data being transmitted. In certain configurations, prior to transmitting the RTS frame, the STA transmits a CTS-to-Self frame in the non-ELR format.

Abstract: Techniques pertaining to enhanced long range (ELR) waveform structures and signal (SIG) subfield in wireless communications are described. An apparatus (e.g., a station (STA)) performs an ELR wireless communication by: (i) transmitting an ELR physical-layer protocol data unit (PPDU); or (ii) receiving the ELR PPDU. The ELR PPDU includes a waveform structure with backward and forward compatibilities with different generations of Wi-Fi standards.
