Abstract: Wireless communication devices, systems, and methods related to power saving, including during connected mode operation and for extended reality (XR) data communications with or without discontinuous reception (DRX), are provided. For example, a method of wireless communication includes receiving, while in a connected mode, a configuration based on data traffic for the wireless communication device, the configuration indicating: a first zone associated with a first set of operating parameters for the wireless communication device; and a second zone associated with a second set of operating parameters for the wireless communication device, the second set of operating parameters being different than the first set of operating parameters; operating in the first zone with the first set of operating parameters to monitor for a first downlink communication signal; and operating in the second zone with the second set of operating parameters.

Abstract: Techniques for wireless communications are described. Control information used to preschedule communication resources may be received and communications may be performed based on the control information using a prescheduling technique. A scheduling type used for the control information may be determined using configuration information, an indication included in the control information, or both. A wireless device that is prescheduled communication resources may not start or not restart an inactivity timer based on the received control information. Also, a wireless device that is prescheduled communication resources may not start a retransmission timer based on the received control information. Additionally, a wireless device that is prescheduled communication resources may also refrain from transmitting a scheduling request based on a duration until a next instance of prescheduled communication resources is expected to occur.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect radio link failure on a master cell group. Accordingly, the UE may determine a state of a secondary cell group (SCG). Additionally, the UE may initiate activation of the SCG based at least in part on the state of the SCG. For example, the activation of the SCG may be initiated based at least in part on the state being a deactivated state, a dormant state, or an enhanced dormant state. Accordingly, the UE may transmit master cell group (MCG) failure recovery information over the SCG and receive, on the SCG, MCG reconnection information. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for uplink traffic alignment and/or uplink traffic aggregation in wireless communication systems. A user equipment (UE) is configured with a mechanism for signaling uplink transmit opportunities to an application client using an application programming interface (API) disposed between a modem of the UE and the application client that enables uplink traffic generated by the application client to be aligned. The API includes semi-static parameters that may be used when a common timer is configured between the application client and the modem, and/or dynamic parameters that may be used when a common timer is not configured between the application client and the modem. The API may also include an extended signaling scheme that may include no-transmission (No-Tx) indications that indicate intervals during which no transmissions are allowed. These No-Tx parameters apply to the semi-static and/or dynamic signaling scheme.

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.
