  • Patent number: 11576123
    Abstract: Logic may define one or more wake-up preambles suitable for high data rates for a wake-up radio (WUR) packet. Logic may define wake-up preamble with different counts of symbols. Logic may generate a wake-up preamble as an on-off keying (OOK) signal. Logic may generate and receive a wake-up preamble that signals a high data transmission rate with respect to data rates defined for WUR packet transmissions. Logic may generate or receive a preamble that signals a rate of transmission of the WUR packet as 250 kilobits per second. Logic may transmit or receive bits of the wake-up preamble as two microsecond orthogonal frequency-division multiplexing (OFDM) based pulses, wherein each two microsecond OFDM based pulse is based on a 32-point Fast Fourier Transform (FFT) in a 20 Megahertz (MHz) bandwidth, with a subcarrier spacing of 625 Kilohertz (KHz) to produce six subcarriers in a four MHz bandwidth.

  • Patent number: 11569953
    Abstract: Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

  • Publication number: 20220338260
    Abstract: An access point station (AP) communicates with a plurality of non-AP stations (STAs) within a synchronized transmission opportunity (S-TXOP). The S-TXOP may comprise an S-TXOP trigger followed by a plurality of S-TXOP slots. After transmission of the S-TXOP trigger, the AP may encode, for transmission within an S-TXOP slot, a downlink (DL) multi-user physical layer protocol data unit (DL MU-PPDU). The DL MU-PPDU may include a preamble followed by a data field. To indicate that a previously signaled resource unit (RU) allocation is to be used during the S-TXOP slot, the AP may encode the preamble to include an allocation ID of the previously signaled RU allocation in a signal field (SIG) of the preamble and to include a SIG-2 presence indicator to indicate that a second signal field (SIG-2) is not included in the preamble.

  • Publication number: 20220123882
    Abstract: In one example, a first wireless communication station (STA) may be configured to identify an estimated end of a frame transmitted from a second STA to an Access point (AP); and to transmit a transmission to the AP within a Short-Inter-Frame-Space (SIFS) beginning at the estimated end of the frame from the second STA. For example, a duration of the transmission may be no longer than the SIFS. For example, the transmission to the AP may be on a same wireless communication channel as the frame from the second STA. In another example, an AP may be configured to process a frame from a first STA; and to process a transmission from a second STA, the transmission from the second STA received within a SIFS beginning at an end of the frame from the first STA.

  • Patent number: 11229052
    Abstract: Methods and systems herein provide better downlink (DL) data throughput for cell-edge stations (CE STAs). The systems enable protection from a third-party collision during a wideband DL data transmission to the cell edge STA, when the wideband control frame, such as clear-to-send (CTS) or acknowledge (ACK), transmission from a cell edge STA cannot reach the AP. This process can be achieved by designing a new wideband control frame comprising: a legacy preamble sent over the primary 20 MHz channel that can be decoded by the legacy STAs, a new preamble sent over the primary 20 MHz channel that can be used to identify the new wideband control frame (this new preamble has the total signal bandwidth information for the rest of the packet following the new preamble); and duplicate legacy control packets set over the total bandwidth indicated in the new preamble (the legacy control packets can be decoded by the legacy STAs).
