  • Patent number: 12075335
    Abstract: This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.

  • Publication number: 20240255810
    Abstract: A liquid crystal display panel and a manufacturing method thereof are provided. By allowing a thickness of an insulating layer in an opening area to be less than a thickness of the insulating layer in a non-opening area, a storage capacitance between a first electrode layer and a second electrode layer in the opening area can be increased, a driving voltage of the liquid crystal display panel can be reduced, and power consumption can also be reduced. Meanwhile, since a parasitic capacitance is small, requirements of small parasitic capacitances and low power consumption of the liquid crystal display panel can be simultaneously achieved.
