Abstract:
Techniques pertaining to transmission methods of probabilistic shaping (PS) modulation in wireless communications are described. An apparatus (e.g., station (STA)) processes each subblock of a plurality of subblocks of a data unit by padding each subblock after scrambling and PS mapping each subblock to result in each subblock having a fixed length before further processing including encoding and modulation. The apparatus then transmits the plurality of processed subblocks.
Abstract:
Techniques pertaining to optimization of distributed-tone resource unit (RU) pilot tone designs in wireless communications are described. An apparatus (e.g., station (STA)) generates a distributed-tone RU (dRU) with a respective position of each of one or more pilot tones shifted with a respective position of each of one or more other pilot tones kept unchanged. The apparatus then performs a wireless communication in a 20 MHz or 40 MHz bandwidth with the dRU.
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.

Techniques pertaining to scalable waveform and numerology designs for next-generation wireless local area networks (WLANs) in 60 GHz frequency band are described. A first apparatus communicates in a 60 GHz frequency band wirelessly with a second apparatus based on a scalable waveform and numerology design with at least one of: (i) selection of a specific subcarrier spacing (SCS); (ii) selection of a specific guard interval (GI) design; and (iii) reuse of a preexisting channelization or tone plan.
Abstract:
A method of combined direction finding (DF) and fine timing measurement (FTM) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device (AP) can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas, which allows a receiving device (STA) to resolve multiple DF sounding signals transmitted from the multiple antennas and thereby estimating angle of departure (AoD). On the other hand, the AP can estimate angle of arrival (AoA) from radio signals transmitted from the STA. When the radial resolution error of AoD or AoA positioning increases, DF positioning and fine-timing measurement (FTM) ranging can be jointly applied to reduce the radial resolution error and extends the AoD/AoA service area with positing accuracy.
Abstract:
A method for downlink traffic priority indication is provided. A wireless device, such as an access point, receives signals destined to a first wireless station and a second wireless station. Since the first wireless station and the second wireless station are associated with the wireless device, the wireless device sends a notice signal to the first wireless station and the second wireless device to inform about the signals. The notice signal sent by the wireless device includes downlink priority information according to the signals such that the wireless stations can manage the downlink traffic accordingly.
Abstract:
Various schemes pertaining to distributed-tone resource unit (DRU)-based enhanced long range (ELR) communication schemes in wireless local area networks (WLANs) are described. An apparatus (e.g., an access point (AP) or a non-AP station (STA)) generates a DRU-based PPDU. The apparatus transmits the PPDU in an ELR communication.
Abstract:
Techniques pertaining to distributed-tone resource unit (DRU or dRU) transmission of frequency subblocks or frequency segments of wide bandwidths in wireless communications are described. An apparatus (e.g., station (STA)) generates a DRU with tones or subcarriers of the DRU distributed in a frequency segment or subblock. The apparatus then communicates wirelessly with the DRU in the frequency segment or subblock of a bandwidth of 240 MHz or wider.
Abstract:
Techniques pertaining to distributed-tone resource unit (DRU) allocation and scheduling for mixed-distribution bandwidth operations in wireless communications are described. An apparatus (e.g., access point (AP)) allocates a plurality of DRU sizes on a plurality of distribution bandwidths to a plurality of stations (STAs). The apparatus then communicates with one or more of the plurality of STAs with a plurality of DRUs that are scheduled with one or more of the plurality of DRU sizes on one or more of the plurality of distribution bandwidths such that there is no overlap of tones of the plurality of DRUs.
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.
