  • Publication number: 20250226937
    Abstract: A wireless device configured for communication in a wireless local area network (WLAN) may determine whether a detected physical layer protocol data unit (PPDU) is an enhanced long range (ELR) PPDU or a non-ELR PPDU and may estimate a power level for a data field of the detected PPDU. The device may use the estimated power level for determining a PHY-CCA indication primitive. The estimated power level for an ELR data field may be determined based on predetermined power boost levels of one or more fields in the ELR PPDU. For a spatial reuse transmission, a transmit power level may be determined based on the estimated power level for the ELR data field. A ELR PPDU may comprise a legacy preamble followed by a ELR preamble and an ELR data field. The ELR preamble may comprise an ELR classification field followed by an ELR-STF, an ELR-LTF and an ELR-SIG.

  • Publication number: 20250225122
    Abstract: Techniques are provided for storage tier verification checks. A determination is made that a mount operation of an aggregate of a set of volumes stored within a multi-tier storage environment has completed. A first metafile and a second metafile are maintained to track information related to the storage of objects of a volume of the aggregate within a remote object store that is a tier of the multi-tier storage environment. A distributed verification is performed between the first metafile and the second metafile to identify an inconsistency. Accordingly, the first metafile and the second metafile are reconciled to address the inconsistency so that storage information within the first metafile and the second metafile are consistent.

  • Patent number: 12355566
    Abstract: This disclosure describes mechanisms for performing rate matching in low-density parity check (LPDC) codes in a wireless network. A device may generate an Aggregated Media Access (MAC) Protocol Data Unit (AMPDU) payload having an AMPDU payload size associated with a number of bits. The device may omit pre-Forward Error Correction (FEC) padding of the AMPDU payload at a MAC layer by indicating the AMPDU payload size in a physical layer (PHY)-specific preamble. The device may then generate the PHY-specific preamble comprising the AMPDU payload size without the pre-FEC padding. The device may also calculate a number of Orthogonal Frequency Division Multiplexing (OFDM) symbols for containing the number of bits and transmit the PHY-specific preamble and the number of OFDM symbols to a station device.

  • Publication number: 20250210108
    Abstract: Technology for operating word line switch transistors in a memory system. A memory system provides for separate control of the voltage to the gates of the word line switch transistors and a voltage to a well in which the word line switch transistors reside. This allows for a negative voltage to be applied to the gates and/or the well. However, if desired, a non-negative voltage (e.g., 0V) may be applied to the gates or the well.

  • Patent number: 12342575
    Abstract: The invention provides a semiconductor structure and a manufacturing method making the semiconductor structure. The method includes: providing a substrate; forming semiconductor pillars on the substrate; forming gate electrodes on the middle sidewalls of the semiconductor pillars; and performing dopant implantation to form source and drain regions. Since the gate-all-around (GAA) gates surrounding the semiconductor pillars are formed first, and the source region and the drain region are formed later by doping implantation, the precise position of the doping implantation can be ensured, thereby improving the fabrication accuracy of the semiconductor structure and improving the performance of the semiconductor structure.
