Patent number: 11838227Abstract: This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to pilot tone designs that support distributed transmission. A transmitting device may modulate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) on a number (M) of tones representing a logical RU associated with the legacy tone plan and may further map the M tones to M noncontiguous subcarrier indices associated with a wireless channel. The transmitting device may transmit the PPDU, over the wireless channel, with a number (N) of pilot tones each having a respective location relative to the M tones as mapped to the M noncontiguous subcarrier indices. In some implementations, the relative locations of the N pilot tones may be different than relative locations of a number (K) of pilot tones associated with the logical RU.Type: GrantFiled: July 30, 2021Date of Patent: December 5, 2023Assignee: QUALCOMM IncorporatedInventors: Lin Yang, Bin Tian, Youhan Kim, Qifan Chen

Patent number: 11817981Abstract: This disclosure provides methods, devices and systems for increasing carrier frequencies for wireless communications in wireless local area networks (WLANs). Some implementations more specifically relate to packet designs and numerologies that support wireless communications on carrier frequencies above 7 GHz. In some aspects, a wireless communication device may up-clock a physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) for transmission on carrier frequencies above 7 GHz, where the PPDU conforms to an existing PPDU format associated with carrier frequencies below 7 GHz.

Patent number: 11813422Abstract: Inflatable devices are disclosed including a surface which has a network of polymer chains and is configured to be inflatable into a therapeutically or diagnostically useful shape, and at least one ultrashort laser pulse-formed modification in the surface. The network can, for example, include a network morphology that is substantially unchanged by modification with the ultrashort pulse laser. Ultrashort laser pulses can be laser pulses equal to or less than 1000 picoseconds in duration. Advantageously, the etching process uses a relatively low-heat laser to avoid significant heating of surrounding polymers while modifying the surface (and other structures) of the device. The process is configured so that the polymer chain morphology adjacent the modification is substantially unaffected by the low-heat laser. The resulting inflatable device has customized surface features while still retaining substantially homogenous polymer network morphology.Type: GrantFiled: April 19, 2022Date of Patent: November 14, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Pu Zhou, Bin Tian, Yidong M.

Patent number: 11818061Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for preventing or reducing cross-network interference associated with a coordinated transmission on a wireless channel. A first access point (AP) of a first basic service set (BSS) and a second AP of a second BSS can concurrently use the wireless channel using a coordinated transmission during a portion of a transmission opportunity (TXOP). The TXOP owner (such as the first AP) may allocate a resource assignment to the second AP such that the resource assignment is conditionally available for use by the second AP in a coordinated transmission. The condition may prevent the resource assignment from being used by the second BSS when its use would cause interference to the first BSS. The condition may be based on a transmit power for downlink communication or uplink communication in the second BSS.Type: GrantFiled: September 30, 2019Date of Patent: November 14, 2023Assignee: QUALCOMM IncorporatedInventors: George Cherian, Alfred Asterjadhi, Abhishek Pramod Patil, Bin Tian, Sameer Vermani
