Abstract: Disclosed are methods and systems for intelligent adjustment of an immersive multimedia workload in a portable computing device (“PCD”), such as a virtual reality (“VR”) or augmented reality (“AR”) workload. An exemplary embodiment monitors one or more performance indicators comprising a motion to photon latency associated with the immersive multimedia workload. Performance parameters associated with thermally aggressive processing components are adjusted to reduce demand for power while ensuring that the motion to photon latency is and/or remains optimized. Performance parameters that may be adjusted include, but are not limited to including, eye buffer resolution, eye buffer MSAA, timewarp CAC, eye buffer FPS, display FPS, timewarp output resolution, textures LOD, 6DOF camera FPS, and fovea size.

Abstract: Disclosed are methods and systems for proactive power and performance management of workloads in a portable computing device (“PCD”), such as, but not limited to, a virtual reality (“VR”) or augmented reality (“AR”) workload. An exemplary embodiment determines that a target application (or an application queued for execution) is compatible with a proactive throttling policy. Advantageously, for those applications that are compatible with a proactive throttling policy, embodiments of the solution may rely on historical performance data of those applications to preset performance parameters such that the PCD may deliver a consistent user experience over time uninterrupted by fluctuations in processing performance resulting from reactive thermal throttling policies.

Abstract: A method, system, and computer program for adaptively streaming multimedia content is disclosed. An adaptive stream manager monitors at least one parameter of a user terminal. The adaptive stream manager monitors at least one parameter of the user terminal and predicting a future value of at least one parameter of the user terminal. The adaptive stream manager also selects a target characteristic, based on the predicted future value of the at least one parameter of the user terminal, and requests a multimedia segment having the target characteristic from a media server.

Abstract: Efficient data processing apparatus and methods include hardware components which are pre-programmed by software. Each hardware component triggers the other to complete its tasks.

Abstract: Techniques for managing resources at a wireless device are described. In one aspect, the wireless device controls applications based on resource demands and available resources. Processing demands by the applications may be monitored, and at least one of the applications may be controlled based on the processing demands and a maximum processing capacity of a processing unit executing the applications. A data application may be controlled by reducing the amount of data exchanged by the application when high processing demands are detected, and vice versa. In another aspect, the wireless device varies resource capacity to match resources demands. The processing capacity of the processing unit may be adjusted based on the processing demands. Higher clock frequency may be selected for the processing unit when the processing demands exceed a high threshold, and lower clock frequency may be selected when processing demands fall below a low threshold.

Abstract: A method of establishing transmission control protocol (TCP) connections is disclosed and may include receiving a uniform resource locator (URL) as part of a hyper text transfer protocol (HTTP) request. Further, the method may include searching a host database with the URL and determining whether host data for the URL is available. The method may also include performing a domain name service (DNS) lookup for a URL host and for one or more sub-resource hosts, wherein all DNS lookups are performed in parallel at substantially the same time, when host data for the URL is available.

Such systems and methods are provided to simplify logic designs and mitigate processing steps during wireless network data processing.

Abstract: A generic quality of service (QoS) model that is not dependent on network technology is used to support QoS for communication networks utilizing different network technologies. The generic QoS model may include a superset of all QoS parameters for all network technologies being supported, e.g., 3GPP and 3GPP2. An application at a device may specify QoS for a traffic flow based on the generic QoS parameters in the superset. The generic QoS parameters may be converted to QoS parameters that are specific to a serving network. The converted QoS parameters are exchanged with the serving network and are used while exchanging traffic with the serving network.

Abstract: Multiple memory pools are defined in hardware for operating on data. At least one memory pool has a lower latency that the other memory pools. Hardware components operate directly on data in the lower latency memory pool.

Abstract: Techniques for controlling discontinuous transmissions in a wireless communication system are described. A method and apparatus for transmitting data on an uplink includes tracking past performance of at least one of an uplink channel condition and uplink system resources. A prediction of a likelihood of a completed or successful data transmission is performed. A long preamble is transmitted with an uplink control channel when the prediction indicates a likelihood of completion of the data transmission. When past performance indicates an unlikelihood of completing the transmission of the data, then the discontinuous mode is maintained without data transmission.

Abstract: Systems and methodologies are described that facilitate enhanced data service functionality for data services operating in a multi-processor computing environment. As described herein, respective processors and/or other components can be utilized to form a Smart Peripheral Subsystem (SPS). As further described herein, the SPS can operate in association with a modem processor and an application processor at a mobile computing device in order to reduce loading at the application processor and improve memory usage efficiency. In the case of a mobile computing device sharing a network connection with a tethered computing device, the SPS can couple a modem interface associated with the mobile computing device and an interface through which the disparate computing device is tethered to the mobile computing device such that operations such as Layer 2 (L2) framing and/or de-framing, Network Address Translation (NAT), or the like can be offloaded to the SPS under various circumstances.

Abstract: Methods and apparatus are presented for extending the protocol synchronization period between a PPP client and a PPP server, wherein the PPP server is located on a wireless communication device. In one aspect, the PPP server generates and sends an IPCP Configure-Nak message to the PPP client whenever the PPP client sends an IPCP Configure-Request message, wherein an arbitrary non-zero value is deliberately sent as the primary DNS address, the secondary DNS address, the primary WINS address, or the secondary WINS address is sent in the IPCP Configure-Nak message. The IP address is deliberately omitted from the IPCP Configure-Nak message.
