  • Publication number: 20220377727
    Abstract: This disclosure provides methods, devices and systems for amplitude shaping encoding, and specifically, for indicating boundaries in bitstreams encoded using amplitude shaping encoding. In some aspects, a transmitting device may insert, into an bitstream to indicate a boundary, a sequence of amplitude bits not associated with any patterns of bit values in a lookup table used for the encoding. In some other aspects, a transmitting device may monitor a length of the amplitude bits in a bitstream during the encoding and stop the encoding on information bits at an end of a current data unit responsive to the length reaching a threshold. In some other aspects, a transmitting device may monitor the length of the information bits and, for each data unit, determine whether a boundary is or would be reached.

  • Patent number: 11509416
    Abstract: 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 tone mapping techniques and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support duplicate (or “DUP mode”) transmissions with channel puncturing. In some implementations, a wireless communication device may transmit a PPDU carrying user data over a wireless channel excluding one or more punctured subchannels, where the user data is transmitted in a DUP mode. As such, the user data may be mapped to a number (N) of tones spanning a first portion of the wireless channel and a duplicate copy of the user data may be mapped to N tones spanning a second portion of the wireless channel.

  • Publication number: 20220369315
    Abstract: 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 physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.

  • Patent number: 11496924
    Abstract: This disclosure provides methods, devices and systems of wireless communication in accordance with hybrid automatic repeat request (HARQ) techniques. Some implementations more specifically relate to aligning aggregate medium access control (MAC) protocol data unit (A-MPDU) subframes with codeword boundaries in a physical-layer service data unit (PSDU). The alignment may be performed by selectively adding padding bits to the PSDU based on the size of each A-MPDU subframe and the lengths of the codewords. In some aspects, an A-MPDU subframe may be aligned with a first codeword of the PSDU so that the first A-MPDU subframe is encoded exclusively within the first codeword. In some other aspects, an A-MPDU subframe may be aligned with two or more contiguous codewords of the PSDU so that the two or more contiguous codewords include the A-MPDU subframe and no portions of any other A-MPDU subframe.

  • Publication number: 20220353049
    Abstract: 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 trigger frame and physical layer convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, an access point (AP) may transmit a trigger frame soliciting a trigger-based (TB) PPDU from a wireless station (STA), where the trigger frame carries RU allocation information indicating a number (N) of tones allocated for the STA and carries tone distribution information indicating whether the N tones are allocated for a contiguous transmission or a distributed transmission. In some other implementations, an AP or a STA may transmit a PPDU carrying distributed signaling information indicating whether the PPDU is transmitted as a contiguous transmission or a distributed transmission.

  • Publication number: 20220345187
    Abstract: This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitter device transmits sounding sequences configured for channel estimation over a wireless channel to a receiver device. The transmitter device also transmits or receives non-sounding frames associated with a channel report of the receiver device. The transmitter device transmits a frame soliciting the channel report from the receiver device. The transmitter device receives the channel report, which may include channel state information (CSI) of the wireless channel responsive to at least the sounding sequences. Some types of channel reports may take longer to generate than other types of channel reports. Transmitting or receiving the non-sounding frames during the time period may prevent other devices from accessing the wireless channel when the receiver device needs additional time to generate a certain type of channel report.

  • Publication number: 20220338057
    Abstract: This disclosure provides methods, devices and systems for soliciting trigger-based (TB) physical layer protocol convergence protocol (PLCP) protocol data units (PPDUs). Some implementations more specifically relate to trigger frame and PPDU designs that support RU downsizing. For example, an access point (AP) may transmit a trigger frame soliciting a TB PPDU from a wireless station (STA). In some aspects, the trigger frame may carry RU allocation information indicating the allocated RU or MRU (associated with a wireless medium) and downsizing information indicating whether downsizing of the RU or MRU is permitted. If interference is detected in a portion of the wireless medium, and downsizing is permitted, the STA may transmit the TB PPDU on a downsized RU or MRU. The downsized RU or MRU includes a subset of the tones in the RU or MRU allocated by the trigger frame.

  • Patent number: 11477745
    Abstract: This disclosure provides systems, methods, apparatus, including computer programs encoded on computer storage media for orthogonal multiplexing of high efficiency (HE) and extremely high throughput (EHT) wireless traffic. Devices in a wireless local area network (WLAN) may operate under HE or EHT conditions. An access point (AP) may support both HE and EHT communications with WLAN devices. To enable substantially simultaneous downlink HE and EHT transmissions and substantially simultaneous uplink HE and EHT transmissions, the AP may support orthogonal frequency-division multiple access (OFDMA) of HE and EHT transmissions. For example, pre-HE and pre-EHT modulated fields, HE and EHT modulated fields, and payloads may be aligned in time for the HE and EHT transmissions. The AP may ensure orthogonality for multiplexing the HE and EHT transmissions based on the alignment. In some implementations, a trigger frame may be utilized to indicate uplink transmission alignments.
