  • Publication number: 20250007586
    Abstract: Methods, systems, and devices for wireless communication are described to support reducing a time domain selectivity of a downlink channel with multiple signal paths. A base station may spatially precode multiple channel state information reference signals (CSI-RSs) and transmit the spatially precoded CSI-RSs to a user equipment (UE), where at least one spatially precoded CSI-RS may correspond to each signal path. Based on the spatially precoded CSI-RSs, the UE may determine a mean or average Doppler shift for each signal path. The UE may transmit, to the base station, signaling indicative of the respective average Doppler shifts for each signal path. Based on the indication of the Doppler shifts, the base station may spatially and temporally precode one or more downlink transmissions to the UE, which may reduce the time domain selectivity of the downlink channel.

  • Patent number: 12147330
    Abstract: In an approach for smart test data workload generation, a processor receives a plurality of expected image frames for a user interface application to be tested. The plurality of expected image frames is pre-defined and represents a series of workflows and operations of the user interface application to be expected based on a design requirement. A processor calculates a first set of hash-values for each corresponding expected image frame. A processor samples the user interface application with a frequency to a plurality of testing image frames during a test run on the user interface application. A processor calculates a second set of hash-values for each sampled testing image frame. A processor compares the first set of hash-values to the second set of hash-values. A processor verifies that the second set of hash-values matches the first set of hash-values.

  • Patent number: 12136973
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.

The first set of channel coefficients correspond to a first precoded portion of the wireless transmission, and the set of port attributes and the second set of channel coefficients correspond to a second portion of the wireless transmission. The BS modifies at least one of the precoders based on the channel state reports. Other aspects, embodiments, and features are also claimed and described.

  • Publication number: 20240313838
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support compression of channel information (e.g., channel feedback) in accordance with multiple compression schemes, from which a transmitting device may select for a channel reporting transmission. For example, a user equipment (UE) may be configured with multiple channel state information compression schemes, corresponding to different encoders or decoders, which may involve various machine learning or neural network techniques. The UE may select or otherwise determine which compression scheme to use for channel reporting in various scenarios, including a selection based on whether a compression scheme maintains relatively accurate reporting, or whether a more power-intensive or processor-intensive compression scheme is supported by an operating mode of the UE, among other selection criteria.

  • Publication number: 20240275440
    Abstract: Aspects of the present disclosure provide techniques for reducing channel state information (CSI) feedback overhead sent from one or more user equipments (UEs) to a network entity, such as a base station (BS) or gNodeB (gNB), while ensuring correct mapping of the CSI feedback at the network entity. In some cases, the overhead reduction may be achieved by converting the CSI feedback to size-reduced and further quantized representative coefficients (e.g., for multiple UEs). The quantized coefficients allow the network entity to recover the CSI feedback by de-quantizing and correctly mapping the quantized coefficients to recover the CSI feedback.
