  • Publication number: 20210288768
    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. An example apparatus selects a resource unit (RU) for a physical (PHY) layer convergence protocol (PLCP) protocol data unit (PPDU). The selected RU includes a set of contiguous tones spanning a bandwidth. The apparatus maps the set of contiguous tones to a set of non-contiguous tones distributed across the frequency spectrum, and transmits the PPDU over the set of non-contiguous tones. Another example apparatus selects an RU of a group of RUs that collectively span a frequency spectrum, and formats a PPDU based on a first frequency bandwidth wider than the selected RU's bandwidth. The apparatus parses the contiguous tones of the selected RU to a set of non-contiguous tones spanning a unique segment of a second frequency bandwidth wider than the first frequency bandwidth, and schedules a transmission of the PPDU over the set of non-contiguous tones.

  • Publication number: 20210281454
    Abstract: This disclosure provides methods, devices and systems that support communicating using orthogonal frequency division multiple access (OFDMA) according to a tone plan that supports 20 MHz subchannel puncturing within a wireless channel. In some aspects, a non-legacy tone plan may define a set of tones for a resource unit (RU) such that the RU does not overlap a 20 MHz subchannel boundary of the wireless channel. The locations of the set of tones in the non-legacy tone plan may be shifted relative to corresponding tones associated with a corresponding RU according to a legacy tone plan. One or more of the disclosed tone plans may enable puncturing of subchannels while making use of some RUs that would otherwise partially overlap a punctured subchannel in the legacy tone plan.

  • Patent number: 11108442
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may determine that a channel is reciprocal and perform an implicit sounding process. During the implicit sounding process, the wireless device may estimate the uplink channel by measuring a first uplink multi-user multiple input multiple output (MU-MIMO) transmission. The wireless devices may then update the uplink channel estimation based by measuring a second MU-MIMO transmission that is received after a downlink transmission from the wireless device. Based on the updated uplink channel estimation, the wireless device may send a beamformed MU-MIMO transmission to a number of other wireless devices.

  • Patent number: 11109278
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiplexing clients of different generations in trigger-based transmissions, including trigger-based transmissions in extremely-high throughput (EHT) Wi-Fi systems. An access point (AP) may generate a trigger frame compatible with two types of stations (STAs), such as EHT STAs and legacy (or high efficiency (HE)) STAs. The AP may transmit the trigger frame to a group of STAs, where legacy STAs may process the trigger frame a legacy trigger frame. EHT STAs may process the trigger frame to determine resource unit (RU) allocations for uplink transmissions in a bandwidth greater than a legacy bandwidth. An EHT STA may determine the resources in the larger bandwidth based on an EHT RU allocation table, a legacy RU allocation table and an additional bit in the trigger frame, or an ordering of RU allocations in the trigger frame.

  • Publication number: 20210243058
    Abstract: This disclosure provides methods, devices and systems for encoding data for wireless communication to achieve probabilistic amplitude shaping. In some implementations, a transmitting device may achieve a fixed information block length (N), at least in part, by iteratively encoding the information bits until the number of amplitude-shaped bits combined with the number of unshaped bits is greater than or equal to a maximum payload length. For example, the maximum payload length may be equal to N. If the resulting number of amplitude-shaped bits plus the number of unshaped bits is less than N, the transmitting device may add one or more padding bits to the information block to achieve the fixed information block length.

  • Publication number: 20210211229
    Abstract: This disclosure provides methods, devices and systems for encoding data in wireless communications. Some implementations more specifically relate to performing a first encoding operation on data bits of a code block to shape the amplitudes of the resultant symbols such that the amplitudes have a non-uniform distribution. In some aspects, the probabilities associated with the respective amplitudes generally increase with decreasing amplitude. For example, the non-uniform distribution of the amplitudes of the symbols may be approximately Gaussian. In some aspects, the first encoding operation is or includes a prefix encoding operation having an effective coding rate greater than 0.94 but less than 1. The first encoding operation is followed by a second encoding operation that also adds redundancy but does not alter the data bits themselves. In some aspects, the second encoding operation is or includes a low-density parity-check (LDPC) encoding operation associated with a coding rate greater than 5/6.
