  • Patent number: 11870626
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device allocated two sets of non-contiguous frequency domain resources may divide a set of modulation symbols associated with a codeword into two subsets of modulation symbols. The wireless device may map the two subsets of modulation symbols into two sets of pre-discrete Fourier transform (DFT) resource elements (REs). The wireless device may pad the pre-DFT REs according to a block based scheme or a comb based scheme. The wireless device may perform a first DFT on the first set of pre-DFT REs and a second DFT on the second set of pre-DFT REs to generate first and second sets of frequency domain samples. The wireless device may perform an inverse fast Fourier transform on the first and second sets of frequency domain samples to generate a time domain waveform that may have a low peak to average power ratio.

  • Patent number: 11860881
    Abstract: A method, system, and processor-readable storage medium are directed towards generating a report derived from data, such as event data, stored on a plurality of distributed nodes. In one embodiment the analysis is generated using a “divide and conquer” algorithm, such that each distributed node analyzes locally stored event data while an aggregating node combines these analysis results to generate the report. In one embodiment, each distributed node also transmits a list of event data references associated with the analysis result to the aggregating node. The aggregating node may then generate a global ordered list of data references based on the list of event data references received from each distributed node. Subsequently, in response to a user selection of a range of global event data, the report may dynamically retrieve event data from one or more distributed nodes for display according to the global order.

  • Patent number: 11863272
    Abstract: The described techniques relate to improved methods, systems, devices, or apparatuses that support channel state information feedback for semi-open-loop and open-loop schemes. The described techniques provide for a user equipment (UE) to determine an open-loop, semi-open-loop, or closed-loop transmission scheme for deriving channel quality information (CQI). In the case of determined open-loop transmission scheme, the UE may select a transmission scheme corresponding to a time offset value and a precoder cycling granularity value. The UE may determine one or more of a time offset value, a precoder cycling granularity value, and a precoding matrix indicator (PMI) for a channel state information (CSI) report, and generate CQI accordingly. Additionally, the UE may include the determined values in the CSI report to indicate the transmission scheme used for the CQI derivation. Based on the CQI, the base station can then determine the transmission scheme and perform link adaption accordingly.

  • Publication number: 20230421219
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may support communication of a compressed channel state information (CSI) feedback. The UE and the network entity may use closed-loop feedback to improve beamforming tracking accuracy. For example, the UE may receive a CSI reference signal (CSI-RS) that is beamformed based on a channel estimate of a sounding reference signal (SRS) or a previous CSI feedback, or both. The UE may transmit a feedback message including compressed CSI that is generated through encoding a measurement of the CSI-RS. The compressed CSI may be generated based on a predicted channel estimate at the network entity, determined based on the channel estimate of the SRS or the previous CSI feedback.
