Abstract: A system for performing peak current mitigation in an application programming subsystem (APSS) dynamically performs mitigation based at least in part on power rail voltage and leakage current obtained at boot time. The voltage and leakage current obtained at boot time are used to estimate peak current. A map that is generated prior to boot time maps estimated peak current to throttling level and dictates different levels of throttling to be performed for different ranges of estimated peak current. At boot time, the map is used to map the estimated peak current to a level of throttling to be applied. If conditions at run time indicate that peak current is occurring or is likely to occur soon, the mapped level of throttling is applied to mitigate the peak current.

Abstract: Methods, systems, and devices for wireless communications are described for uplink transmit power determination in which a user equipment (UE) may be configured for carrier aggregation of multiple concurrent uplink component carrier (CC) transmissions. The UE may apply an adjustment to a maximum transmit power limit (MTPL) for one or more CCs when the UE is configured for uplink carrier aggregation. The MTPL adjustment may be applied to reduce a transmit power of one of the CCs when a maximum transmit power is requested for the CC. The MTPL adjustment may reduce the transmit power to be less than the MTPL of the UE and thereby provide that one or more other CCs may still have some transmission power. The UE may compute a MTPL adjustment based on a static value or on a per-subframe basis based on scheduling parameters and a requested transmit power for each CC.

Abstract: Sidelink (SL) positioning of user equipments (UEs) is supported by providing with SL positioning reference signals (PRS) an indication of the identity of the SL positioning session and the SL PRS source identifier. A UE may transmit a payload-based indication or a sequence-based indication of the identity of the SL positioning session and the source identifier. The pay-load based indication is included in, e.g., a Layer 1 (L1) and/or Layer 2 (L2) control message associated with the SL PRS. The sequence-based indication may be generated using the indication of the identity of the SL positioning session and the source identifier to initialize or seed the generation of the PRS sequence, scramble the PRS sequence, or generate a cover code that is applied to the PRS sequence.

Abstract: Ranging operations may be performed between an initiator device and a responder device using data frames as opposed to fine timing measurement (FTM) frames or Null Data Packet (NDP) frames. An initiator device may request the responder device to perform a ranging operation. The responder device may transmit a data frame to the initiator device and may receive an acknowledgement (ACK) frame from the responder device. The responder device may transmit a second data frame to the initiator device that includes ranging measurement information for the previous message exchange, including a time of departure of the data frame and a time of arrival of the ACK frame. Because data frames are encrypted, the ranging measurement information is provided in a secure manner. Moreover, by including the ranging measurement information in data frames, throughput for the ranging procedure is improved.

Abstract: Aspects are provided including one or more techniques for graphics processing involving hierarchical modulation and foveated rendering. A first wireless device obtains, from a network entity, a hierarchical modulated image including higher and lower priority bits. The first wireless device also obtains gaze information from a second wireless device indicating an associated foveal region. In response to the gaze information, the first wireless device processes a portion of the hierarchical modulated image associated with the lower priority bits using the gaze information. For example, the device decodes low priority bits in the hierarchical modulated image in regions closer to the fovea. The first wireless device subsequently provides an image including the processed portion to be rendered at the second wireless device. For example, the processed image may have a higher resolution in the regions closer to the fovea but a lower resolution in regions farther from the fovea.

The UE can determine a data message based on the first transmission and the second transmission.
