  • Patent number: 11949249
    Abstract: A wireless power transmitter may receive a request from a wireless power receiver to perform recalibration for a first type of foreign object detection (FOD) in response to the wireless power receiver attempting to change an electromagnetic parameter supplied by the wireless power transmitter. In response to receiving the request, the wireless power transmitter may perform a second type of FOD to produce a FOD result. When the FOD result indicates a foreign object is present or likely present, the wireless power transmitter may discontinue or limit wireless power transfer, and/or communicate the FOD result to the wireless power receiver. When the FOD result indicates a foreign object is not present or likely not present, the wireless power transmitter may communicate the FOD result to the wireless power receiver, perform the recalibration and continue with wireless power transfer.

  • Publication number: 20240107541
    Abstract: Mechanisms of uplink resource allocation in a subband full duplex (SBFD) system for transmissions of physical uplink control channel (PUCCH) and sounding reference signal (SRS) are disclosed. A PUCCH or SRS resource configuration can be received from a base station in the SBFD system. The PUCCH or SRS resource configuration can indicate, or provide parameters of, a first frequency domain starting position for PUCCH or SRS transmissions in SBFD slots and a second frequency domain position for PUCCH transmissions in non-SBFD slots. Periodic or semi-persistent PUCCH or SRS transmissions can be performed across multiple slots including SBFD slots and non-SBFD slots based on the PUCCH or SRS resource configuration. The periodic or semi-persistent PUCCH or SRS transmissions across the SBFD slots use the first frequency domain starting position. The periodic or semi-persistent PUCCH or SRS transmissions across the non-SBFD slots use the second frequency domain starting position.

  • Patent number: 11943012
    Abstract: Embodiments of the present invention provide an apparatus and method for a MAP wireless network that includes a collaborative channel sounding measurement phase to determine channel state information between devices (e.g., the channel state between an STA and a collaborative AP) for efficient configuration of the MAP wireless network and to improve the performance of the MAP wireless networks. The wireless AP and wireless STAs associated with the collaborative APs can simultaneously transmit by applying collaborative beamforming where the interferences between channels nullify each other (e.g., nulling), and the beamforming is performed based on a sounding phase performed by the collaborative APs.

  • Patent number: 11916846
    Abstract: A method pertaining to leftover bits processing for proportional round-robin resource unit (RU) parsing in extreme high-throughput (EHT) systems involves processing a stream of bits to provide processed bits. The method also involves transmitting the processed bits to a station (STA) over a combination of multiple resource units (RUs) assigned to the STA. In processing the stream of bits, the method may involve parsing the stream of bits to the combination of multiple RUs. Moreover, in an event of leftover bits remaining from the parsing, the method may further involve distributing the leftover bits to one or more RUs but not all RUs of the combination of multiple RUs.

  • Patent number: 11917551
    Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.
