  • Publication number: 20240064106
    Abstract: A user equipment may be configured to implement a procedure for employing flow-based traffic categorization for device optimization. In some aspects, the UE may monitor application traffic of one or more applications installed on the UE, and determine one or more observation features of the application traffic within an observation period. Further, the user equipment may predict, via a machine learning model, a traffic category of the observation period based on the one or more observation features, and apply an optimization to second application traffic of the one or more applications at the UE based on the traffic category.

  • Publication number: 20230417870
    Abstract: Certain aspects of the present disclosure provide techniques for identifying a minimal, or at least reduced, set of representative calibration paths in radio frequency (RF) circuits and calibrating other calibration paths based on calibration codes used for the representative calibration paths. An example method generally includes receiving a calibration data set including measurements associated with each calibration path of a plurality of calibration paths in an RF circuit. Based on a clustering model and the calibration data set, a plurality of calibration clusters is generated. From each respective calibration cluster of the plurality of calibration clusters, a respective representative calibration path for is selected for the respective calibration cluster. Generally, calibration codes generated for the representative calibration path are applicable to other calibration paths in the calibration cluster.

  • Patent number: 11804887
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of reference signals from a base station and may determine a first set of channel state parameters. The UE may determine one or more preprocessed decoder parameters based on a downlink channel decoder of the UE and may perform one or more signal processing operations to determine one or more adjustment values for the first set of channel state parameters. The UE may transmit an indication of a the one or more adjustment values to the base station. In some implementations, the UE may transmit an indication of the one or more preprocessed decoder parameters to the base station and the base station may perform the one or more signal processing operations to determine the one or more adjustment values.

  • Publication number: 20230300671
    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a receiving device, such as a user equipment (UE), may reduce packet congestion associated with communications between the receiving device and a transmitting device, such as a server, via a radio access network (RAN). The receiving device may measure congestion metrics associated with receiving data packets from the transmitting device via the RAN. The congestion metrics may include RAN congestion metrics and transport or application layer congestion metrics associated with the network connection between the receiving device and the transmitting device. The receiving device may estimate packet congestion at the receiving device according to the measured congestion metrics. The receiving device may modify connection parameters of the network connection based on the estimated packet congestion.

  • Publication number: 20230239016
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a signal. The UE may measure the signal to explore one or more inactive ranks or inactive precoders. The UE may transmit, based at least in part on the measuring, a report that includes channel state information for at least one of the one or more inactive ranks or inactive precoders. Numerous other aspects are described.

  • Patent number: 11671202
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.

  • Publication number: 20230098652
    Abstract: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

  • Publication number: 20220368399
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a single layer reference signal. The UE may perform single layer measurements associated with the single layer reference signal for a plurality of UE beam pairs. The UE may determine, based at least in part on the single layer measurements for the plurality of UE beam pairs, multiple layer measurements associated with one or more UE beam pairs of the plurality of UE beam pairs. The UE may select, from the one or more UE beam pairs, a UE beam pair based at least in part on the multiple layer measurements associated with the one or more UE beam pairs. Numerous other aspects are described.

  • Publication number: 20150049651
    Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to dynamically updating filtering configuration in modem baseband processing. A method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes detecting one or more conditions regarding one or more metrics of a received signal and updating, based on the detection, a configuration of one or more filters designed to mitigate an effect of spurious signals associated with (e.g., that fall within) a bandwidth of the received signal.
