Abstract: A wireless communication system, apparatus, and methodology are described for enabling wireless communication devices to generate extended range Physical Layer Protocol Data Units (PPDUs) for wireless transmission to a destination communication devices by generating, at a first wireless communication device, a data sequence in which a plurality of repeated data symbols are encoded for wireless transmission to the second communication device, and then applying a scrambling sequence that is known to the first and second communication devices to the data sequence to generate an output data sequence wherein the plurality of repeated data symbols are pseudo-randomized prior to performing an inverse Fourier transform on the output data sequence.

Abstract: A method for multi-antenna processing in multi-link wireless communication systems includes transmitting by a first MLD, a first capability defining a first number of Spatial Streams (SS) supported by the first MLD for a single link exchange over one of a subset of links from a plurality of links between the first MLD and a second MLD. A second capability is transmitted by the first MLD defining a second number of SS supported by the first MLD for each link of a multi-link exchange. At least one Radio Frequency (RF) chain of the first MLD is configured to enable communication over the subset of links from the plurality of links.

Abstract: Systems, apparatuses and methods described herein provide a method for padding a signal extension of orthogonal frequency-division multiplexing (OFDM) symbols. A transceiver may obtain a plurality of data symbols for transmission, and determine that a number of information bits for a last symbol of the plurality of data symbols is not an integer value. A special padding rule may be applied to add padding bits to the last symbol. A number of coded bits for the last symbol may be determined when the number of information bits for the last symbol has changed, and the plurality of data symbols for data transmission may be encoded based on the determined number of coded bits for the last symbol.
