Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may operate, in connection with a secondary cell group (SCG) for multiple radio access technology dual connectivity, in one of an SCG dormant state in a dormant downlink bandwidth part (BWP) configured for a primary secondary cell of the SCG or an SCG enhanced dormant state in an enhanced dormant downlink BWP configured for the primary secondary cell. The UE may receive a control message associated with activating the SCG for the UE, the control message indicating a BWP switch for the UE. The UE may switch, in connection with receiving the control message, from one of the dormant downlink BWP or the enhanced dormant downlink BWP to an activated downlink BWP in which the UE operates in an SCG activated state. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control information that identifies criteria to use for determining a delivery status of a protocol data unit (PDU) set that includes multiple PDUs. The PDU set may be associated with an application layer of the UE. Accordingly, the UE may receive at least a portion of the PDU set, and may determine the delivery status of the PDU set based on the received portion of the PDU set and the criteria identified by the control information. The delivery status of the PDU set may refer to whether the PDU set was successfully delivered to the UE. The delivery status of the PDU set may be based on a quantity of bits or PDUs in the received portion of the PDU set, a threshold quantity of bits or PDUs, or a combination thereof.

Abstract: Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Abstract: Disclosed are techniques for detecting outlier cells based on positioning of a user equipment (UE). In an aspect, the UE or a location server determines a plurality of cells detectable by the UE, calculates a plurality of location estimates for the UE based on positioning measurements of a corresponding plurality of subsets of the plurality of cells, identifies a subset of cells that provides a best location estimate for the UE, wherein the best location estimate maximizes a set of inlier cells, calculates a final location estimate for the UE based on positioning measurements of the subset of cells and the set of inlier cells, identifies any remaining cells of the plurality of cells other than the subset of cells and the set of inlier cells as at least one outlier cell, and performs a mitigation operation based on identifying the at least one outlier cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a serving base station may locally store secret information (e.g., side information, such as a secret key, a public key, etc.) that is used to protect physical (PHY) layer channel or signal transmissions. The UE and the serving base station may determine a next value of a pseudo random sequence that is a function of a current value of the pseudo random sequence and the secret information and may use the next value to determine a time-varying parameter. The UE and the serving base station may use this time-varying parameter to determine which tones, which symbols periods, or which sequence, is being used for a subsequent communication of a PHY layer channel or signal.

Abstract: Methods, systems, and devices for wireless communication are described related to a duty cycle configuration for power saving. A user equipment (UE) may receive control signaling indicating a duty cycle for cycling between a first power state associated with a first configuration and a second power state associated with a second configuration. In some examples, the first and second configurations may indicate a bandwidth part (BWP) configuration, restricted reception or transmission of one or more channels within the BWP configuration, or both for the UE. The UE may communicate first data traffic in accordance with the first configuration while operating in the first power state. The UE may transition from the first power state to the second power state in accordance with the duty cycle. The UE may communicate second data traffic in accordance with the second configuration while operating in the second power state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a discontinuous reception (DRX) short cadence value that corresponds to a number of Hertz (Hz). The UE may sleep as part of a DRX cycle. The UE may wake up, starting at a subframe, based at least in part on the DRX short cadence value and a subframe identifier of the subframe. Numerous other aspects are described.

Abstract: Methods and systems for providing software applications on a client device with dynamic control over low-latency mode (LLM) operations of the client device. The client device may monitor downlink data packets of a client software application operating on the client device to detect trigger events. The client device may determine operating parameters of the modem based on a detected trigger event and dynamically adjust the low-latency mode of the modem based on the detect trigger event or the determined operating parameters.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a base station, a medium access control-control element (MAC-CE) including an offset change command. The method also includes adjusting an offset within a periodic pattern based on the offset change command. A method of wireless communication, by a base station, includes detecting a misalignment between an arrival time of data relative to a periodic pattern. The method also includes transmitting, to a user equipment (UE), a medium access control-control element (MAC-CE) including an offset change command to adjust an offset within the periodic pattern.
