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 80 MHz distributed-tone resource unit (dRU) tone plan-based dRU designs for wide distribution bandwidths 160 MHz and 320 MHz in wireless communications are described. An apparatus (e.g., station (STA)) generates a distributed-tone resource unit (dRU) using a 80 MHz dRU tone plan as a basic building block. The apparatus then performs a wireless communication in a 160 MHz or 320 MHz distribution bandwidth with the dRU.

Abstract: 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: Methods and apparatus are provided for structured resource allocation signaling. In one novel aspect, an 8-bit RU allocation filed is allocated in the HE-SIG-B common field for each 20 MHz. The structured resource signaling supports more than four MU-MIMO users. In one embodiment, the STA decodes the 8-bit RU allocation signal following a structured resource unit (RU) allocation rule, and determines the RU. In one embodiment, the STA decodes the first two bits of the 8-bit RU allocation signal to determine a first category of the RU allocation. The categories of the RU allocation includes a large RU size category indicating larger than or equal to 20 MHz RUs exist, a two 106-tone category indicating two 106-tone RUs exist, and a no-large-RU category indicating only smaller-than-242-tone RUs exist. The STA further decodes based on the category. A lookup table (LUT) for RU allocation is built and decoded based on a structured signaling rule.

Abstract: Various schemes pertaining to long training field (LTF) and short training field (STF) transmission for wide bandwidth 240 MHz with more direct-current (DC) tones in wireless communications are described. A processor of an apparatus generates either or both of an LTF and a STF of a physical-layer protocol data unit (PPDU) with a center 996-tone resource unit (RU) having more than a predetermined number of DC tones. The processor then performs a wireless communication in a wide bandwidth (e.g., 240 MHz) with the PPDU.

Abstract: Various schemes pertaining to peak-to-average power ratio (PAPR) reduction for resource unit (RU) duplication and tone repetition in wireless communications are described. An apparatus generates a resource unit (RU) or multi-RU (MRU). The apparatus then performs a wireless communication using the RU or MRU with either or both of a RU duplication and a tone repetition such that a peak-to-average power ratio (PAPR) is reduced.

Abstract: Techniques pertaining to enhanced long range (ELR) communication schemes in wireless communications are described. An apparatus (e.g., a station (STA)) performs an ELR communication by either: (i) transmitting an ELR physical-layer protocol data unit (PPDU); or (ii) receiving the ELR PPDU. The ELR PPDU includes a spoofing preamble, an ELR preamble and an ELR data portion.

Abstract: A wireless communicating method includes: performing one resource unit allocation upon a channel; and allocating a first resource unit and a second resource unit in said one resource unit allocation to a station, wherein the first resource unit is different from the second resource unit. By using the wireless communication method, throughput rate can be improved.

Abstract: Systems and methods of expanding indication capabilities of existent PPDU preamble fields. The “GI+LTF Size” field is redefined to indicate a new combination of GI duration and HE-LTF size. The redefinition is indicated when the values of the two other existent fields, in combination, indicate an invalid scenario because the two values should have been mutually exclusive. Particularly, the DCM field and the STBC field are both set to the “enabled” mode as an indication for redefine the “GI+LTF Size” field. Upon receiving such a PPDU, a receiver is configured to resolve the PPDU as neither DCM nor STBC is enabled. Rather, the receiver interprets the particular combination of DCM and STBC values as an indication that the “GI+LTF Size” field is redefined to indicate the new combination of GI duration and HE-LTF size.
