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.

Abstract: Techniques pertaining to narrow bandwidth transmission schemes in next-generation Enhanced Long Range (ELR) wireless local area networks (WLANs) are described. An apparatus (e.g., station (STA)) generates a physical-layer protocol data unit (PPDU) comprising a spoofing preamble, an ELR preamble and an ELR data portion. The apparatus transmits the PPDU in an ELR wireless communication such that at least a portion of the ELR preamble is transmitted on at least one narrow-bandwidth subchannel of a wider bandwidth.

Abstract: Embodiments of the present invention provide methods and devices for performing wireless sensing operations that can accommodate different Rx frequency responses with minimum PHY changes to increase the performance and reliability of wireless sensing in wireless local area network (WLAN) networks. Rx frequency response information can be obtained as channel state information (CSI) in a loopback test and can further be normalized with the total gain in the receiver chain leading to CSI estimation. Moreover, different Rx frequency responses can be categorized into limited groups with underlying circuit conditions based on their frequency response variations. The different Rx frequency responses can be indicated in subfields of a CSI report transmitted to the sensing initiator for performing sensing operations with the sensing responder.

Abstract: Techniques pertaining to performance enhancement of resource unit (RU) duplication with predefined interleaving patterns in wireless communications are described. An apparatus (e.g., station (STA)) generates at least one RU. The apparatus then performs a wireless communication with RU duplication in a frequency domain using either: (a) a same interleaving pattern applied across orthogonal frequency-division multiplexing (OFDM) symbols of each duplicated RU of the at least one RU; or (b) two or more interleaving patterns periodically or alternatively switched over OFDM symbols of two or more duplicated RUs of the at least one RU.

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.

Abstract: Techniques pertaining to further indication for WLAN sensing measurement report in wireless communications are described. A sensing receiver is configured to perform a sensing measurement and generate a sensing measurement report indicating channel state information (CSI) according to the sensing measurement. The sensing measurement report further indicates one or more categories of a frequency response of the sensing receiver without indicating any gain setting of the sensing receiver. The sensing receiver is also configured to transmit, as a sensing responder, the sensing measurement report to a sensing initiator.

Abstract: Techniques pertaining to preamble designs for next-generation wireless local area networks (WLANs) in 60 GHz band are described. A first apparatus communicates in a 60 GHz band wirelessly with a second apparatus by transmitting a first physical-layer protocol data unit (PPDU) to the second apparatus and/or receiving a second PPDU from the second apparatus. Each of the first PPDU and the second PPDU and a respective preamble thereof are either with or without at least partial backward compatibility with one or more preexisting PPDU formats and preambles.
