  • Patent number: 11962444
    Abstract: A first communication device generates a PHY preamble of a PHY data unit to include a first orthogonal frequency division multiplexing (OFDM) symbol corresponding to a legacy signal field. The legacy signal field includes i) a length subfield, and ii) a rate subfield. The length subfield and the rate subfield indicate a duration of the PHY data unit, and the legacy signal field is formatted according to a legacy second communication protocol. The first communication device generates the PHY preamble of a PHY data unit to include a second OFDM symbol corresponding to a duplicate of the legacy signal field, and a plurality of additional OFDM symbols corresponding to a non-legacy signal field. The first communication device sets the length subfield of the legacy signal field to a length value such that a remainder value resulting from dividing the length value by three, indicates that the PHY data unit conforms to the first communication protocol.

  • Patent number: 11902003
    Abstract: Systems and methods related to partial beam correspondence may be used to address potential limitations of beamforming wireless networks. A user equipment electronic device and/or wireless network identifies a subset of available transmitter beams for the user equipment electronic device that are indicated as similar to a downlink reference signal received at the user equipment electronic device from a wireless network node. The user equipment electronic device sweeps the subset of available transmitter beams for communication with the wireless network node and uses a best beam from the sweep to communicate with the wireless network node.

  • Patent number: 11855818
    Abstract: In a method for adapting an orthogonal frequency division multiplexing (OFDM) numerology configuration for use in a communication network one or more OFDM numerology configurations are adaptively selected at a first communication device to be used in communication with one or more second communication devices. Adaptively one or more OFDM numerology configurations includes selecting at least one combination of two or more of (i) a guard interval duration, (ii) a tone spacing, (iii) a starting location of the selected guard interval duration, and (iv) a starting location of the selected tone spacing. A physical layer (PHY) data unit to be transmitted to a second communication device is generated at the first communication device. The PHY data unit is generated using one of the one or more adaptively selected OFDM numerology configurations to generate OFDM symbols of at least a portion of the PHY data unit.

  • Patent number: 11784692
    Abstract: A first communication device transmits a null data packet (NDP) to a second communication device as part of a multi-user beamforming training transmission sequence and receives a first packet from the second communication device responsive to transmitting the NDP. The first packet includes an aggregate media access control protocol data unit (A-MPDU) having a plurality of fragments of beamforming training information that was generated by the second communication device based on the NDP. The first communication device determines that one or more of the fragments were not correctly received by the first communication device and generates a bitmap to indicate a set of at least one fragment that is to be retransmitted by the second communication device. The first communication device transmits a second packet having the bitmap to the second communication device to prompt the second communication device to retransmit the set of at least one fragment.

  • Patent number: 11777691
    Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

  • Patent number: 11751176
    Abstract: Methods and systems include beamformed wireless communications to and from a user equipment electronic device. During operation of the user equipment electronic device, a change in slot aggregation is made. Using the aggregated slots, the user equipment electronic device and/or a wireless network utilize beam sweeps to determine a best beam pairing by repeating a shared channel in the aggregated slots with a beam sweep of multiple beams between the user equipment electronic device and the wireless network.

  • Publication number: 20230208475
    Abstract: Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.

  • Publication number: 20230180201
    Abstract: A bandwidth-limited client station is configured to operate with a maximum bandwidth that is less than a full bandwidth of a communication channel of a wireless local area network. The bandwidth-limited client station negotiates a target wake time (TWT) period with an access point, including negotiating a particular non-primary component channel among one or more non-primary component channels in which the bandwidth-limited client station is expected to operate during the TWT period. The bandwidth-limited client station receives a first legacy packet from the access point in the particular non-primary component channel, the first legacy packet including a beacon frame. The bandwidth-limited client station also receives a trigger frame from the access point in a second legacy packet in the particular non-primary component channel during the TWT period.

  • Publication number: 20230155658
    Abstract: Methods and apparatuses are disclosed for performing fast beam tracking in a wireless communication environment. A UE signals to a gNB its capabilities for intra-symbol beam sweeping. Depending on configuration, the UE can either assume that the intra-symbol beam sweeping configuration will be implemented, or will await a response from the gNB before implementing intra-symbol beam sweeping. Although this is generally carried out during initial access between the UE and the gNB, the beam sweeping configuration can be dynamically updated by either the UE or the gNB during established communication. For example, the UE can signal a desired change via its MAC CE, and the gNB can signal its change to the UE via DCI.

  • Publication number: 20230155765
    Abstract: Features for increasing sounding reference signal (SRS) resource capacity for wireless communications may include introducing a larger comb size with comb hopping, providing support to determine the slot offset and/or comb offset for aperiodic SRS based on downlink control information (DCI) alone or based on both DCI and radio resource control (RRC), applying RB level frequency hopping within an SRS resource across different symbols, and/or applying time domain orthogonal cover code (TD-OCC) to symbols within an SRS resource. The TD-OCC may be applied to SRS for codebook, non-codebook and antenna switching, and may also be applied simultaneously with comb hopping and/or RB level hopping in certain scenarios.
