  • Publication number: 20250109069
    Abstract: Disclosed are gypsum boards and methods of preparing gypsum board using silica fume. The board contains a set gypsum core disposed between two cover sheets. The core is formed from a core slurry comprising water, stucco, and silica fume. The silica fume is dispersed before adding into the gypsum slurry. The gypsum board demonstrates desirable fire-resistance properties when subjected to various high temperature shrinkage and thermal insulation tests according to ASTM C1795-15. The dispersed silica fume surprisingly and unexpectedly allows for enhancing the fire resistance of gypsum board. In embodiments, the presence of the silica fume in the core slurry allows for excluding expandable vermiculite therein.

  • Publication number: 20250096927
    Abstract: An apparatus and method for wireless communication is described in which post-Forward Error Correction (FEC) padding in a Physical Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU) is replaced with non post-FEC data. The data signals include repeating codebits or quadrature amplitude modulation (QAM) symbols of the last codeword. In addition, the coding rate, modulation order, orthogonal frequency division multiplexed (OFDM) symbol duration, and/or transmission bandwidth is able to be reduced, less power is allocated to padding subcarriers, a pre-FEC padding factor is increased, and/or control information piggybacked in the padding. The replacement may be limited to short PPDUs or those exceeding a threshold length. An increase in packet extension duration allows additional processing time.

  • Publication number: 20250070909
    Abstract: For example, a STA may determine a pre-FEC padding factor value for a PPDU, the pre-FEC padding factor value in a range between 1 and 2Na, wherein Na is an integer greater than 2; set Na bits in a Signal (SIG) field of the PPDU to indicate the pre-FEC padding factor value; and encode a data field of the PPDU according to a FEC coding based on the pre-FEC padding factor value. For example, a STA may encode a data field of a PPDU according to a FEC coding based on a pre-FEC padding factor value and based on a condition that no post-FEC padding is to be applied for the PPDU; and set an LDPC extra symbol subfield in a SIG field of the PPDU to indicate whether or not an LDPC extra symbol is present based on encoding of the data field of the PPDU.
