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: 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: 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 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.

Abstract: A new lower density parity check (LDPC) tone mapper is proposed when DCM is applied for a given resource unit (RU) when LDPC is used as the channel control coding. For HE PPDU transmission with DCM, LDPC encoded streams are first modulated by a DCM constellation mapper. The modulated symbols of the lower half of the frequency segment and the modulated symbols of the upper half of the frequency segment are modulated using the same LDPC encoded bits using DCM mapping. The modulated symbols of the lower half of the frequency segment are mapped to lower half of the data subcarriers using DCM LDPC tone mapper. The modulated symbols of the upper half of the frequency segment are mapped to upper half of the data subcarriers using the same DCM LDPC tone mapper. Maximum frequency diversity for DCM can be achieved.

Abstract: Various schemes pertaining to proportional round robin segment parser designs for the wider bandwidths and corresponding multi-resource unit (MRU) combinations with either equal modulation (EQM) or unequal modulation (UEQM) in wireless communications are described. An apparatus (e.g., an access point (AP) or a non-AP station (STA)) generates a multi-resource unit (MRU) comprising an aggregate of a plurality of resource units (RUS). The apparatus then transmits the MRU with UEQM or EQM in a bandwidth of 480 MHz or greater.

Abstract: Various schemes pertaining to distributed-tone resource unit (dRU) operation for wide bandwidths next-generation wireless local area network (WLAN) systems are described. A communication entity generates at least one dRU or both the at least one dRU and at least one regular resource unit (rRU). The communication entity then communicates wirelessly using the at least one dRU or using the at least one dRU and the at least one rRU in a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz bandwidth.

Abstract: Techniques pertaining to distributed-tone resource unit (RU) designs for wide distribution bandwidth 160 MHz in wireless communications are described. An apparatus (e.g., station (STA)) generates a distributed-tone resource unit (dRU) of 52 tones or more using a 26-tone dRU as a building block. The apparatus then performs a wireless communication in a 160 MHz distribution bandwidth with the dRU.
