Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines whether a channel quality indicator (CQI) is to be reported during any one of x subframes immediately after a start of a next on-duration, an on-duration being a duration over which a downlink control channel is monitored every discontinuous reception (DRX) cycle, and x being a number of subframes used to generate a CQI report, schedules a wake-up time for reporting the CQI when the CQI is to be reported during any one of the x subframes immediately after the start of the next on-duration, and reports the CQI based on a reference subframe. The CQI may be based on a last subframe of a previous DRX cycle active time, and reported at a first subframe of the next on-duration.

Abstract: An apparatus for data processing and related non-transitory computer-readable medium are provided. In the method, the apparatus computes a burst threshold for a data stream. The burst threshold is associated with a throughput of the data stream. The apparatus further identifies a set of bursts in the data stream based on the burst threshold, and detect a pattern in the data stream based on the set of bursts. The apparatus further estimates at least one subsequent burst in the data stream based on the pattern and the burst threshold, and outputs an indication of the at least one subsequent burst in the data stream. The method enables a device to predict one or more future data bursts based on characteristics of existing data. The predicted data bursts allow the transmission resource and power to be adaptively arranged to significantly reduce power consumption and improve transmission efficiency.

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. A lookup table is generated associating a respective calibration path with other calibration paths in each respective calibration cluster.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for reporting aperiodic channel quality indicator (A-CQI) in a new Secondary Cell (SCell) state of Long Term Evolution (LTE) carrier aggregation. A User Equipment (UE) receives a request for reporting A-CQI relating to a Scell configured for the UE when the UE is in a first state corresponding to the Scell, the first state designed for a reduced SCell activation latency and to result in the UE using lower power as compared to when the UE is in a second state. The UE, in response to the request, reports the A-CQI for the Scell in accordance with a first A-CQI reporting configuration for the first state which is different from a second A-CQI reporting configuration for the second state.

Abstract: In order to balance the power requirements of a MIMO receiver with the gains that may be achieved through its use, an apparatus determines whether a current configuration of the UE supports iterative MIMO reception. When it is determined that the current configuration of the UE supports iterative MIMO reception, the apparatus determines whether at least one parameter of the received signal is within a corresponding target condition, respectively, for each of the at least one parameters, e.g., including determining whether a scheduling percentage meets a scheduling threshold and whether an error rate is within an error rate range. When both the configuration supports iterative MIMO reception and the signal parameter(s) meet the corresponding target condition(s), the apparatus uses the iterative MIMO receiver. If not, the apparatus uses a serial receiver.

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.
