  • Patent number: 11973626
    Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble and a first and a second signal field. The legacy preamble and the first and second signal fields are generated on the basis of a first and a second phase rotation value. When the broadband corresponds to a 320 MHz band, the first phase rotation value is [1 ?1 ?1 ?1 1 ?1 ?1 ?1 ?1 1 1 1 ?1 1 1 1]. An element of the first phase rotation value is applied to each 20 MHz band of the 320 MHz band. An element of the second phase rotation value is applied to each subcarrier of the 320 MHz band.

  • Patent number: 11895593
    Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.

  • Patent number: 11356309
    Abstract: In some examples, a system includes a receiver configured to receive signals encoding first, second, and third messages in first, second, and third frequency bands. The system also includes a mixer configured to down-convert the received signals to intermediate-frequency (IF) signals based on a local oscillator signal. The system further includes at least one analog-to-digital converter configured to sample the IF signals at a sampling rate. A frequency band of the IF signals encoding the first message falls within a first Nyquist region, and a frequency band of the IF signals encoding the second message falls within a second Nyquist region. The first and second Nyquist regions are frequency ranges bounded by multiples of one-half of the sampling rate, and the second Nyquist region is different from the first Nyquist region. The system includes processing circuitry configured to determine data in the first, second, and third messages based on an output of the at least one analog-to-digital converter.

  • Patent number: 11296846
    Abstract: A UE transmits to a BS an indication of a number of PTRS ports. The number of PTRS ports is a suggestion to the BS for allocating the indicated number of PTRS ports to the UE for transmission of PTRS from the BS to the UE to enable the UE to perform phase tracking. The method also includes allocating, by the BS, PTRS ports to the UE based on the indication of the number of PTRS ports. The indication may be included in a UCI message, MAC CE, or RRC message transmitted by the UE to the BS. The BS may map the allocated PTRS ports to DMRS ports corresponding to spatial streams transmitted by the BS. The UE may estimate CPE of each spatial stream, measure correlations of the estimated CPE among the spatial streams, and use the correlations to determine the suggested number of PTRS.
