A User Equipment(UE) determinesa maximum UL/DL duty cycle to utilize for a connection with a base stationbased on a content of a UE capabilities requestsent by the base station, where the maximum UL/DL duty cycle is typically is less than a most restrictive, possible UL/DL duty cycle of the UE, yet allows the UE to remain SAR compliant. The UE may determinethe maximum UL/DL duty cycle further based on, e.g., requested frequency bands, operational UE transceivers, carrier components, UE power class, stored power data, etc. The UE communicatesthe maximum UL/DL duty cycle for the connection to the base station, thereby resulting in more efficient downlink data delivery during the connection as well as increasing cell site coverage and overall system efficiency. The UE may store a global parameter whose value is indicative of the maximum UL/DL duty cycle.

Embodiments of apparatuses and methods for dynamic prioritization of interconnect traffic in a system-on-chip are described. In an embodiment, an apparatus includes first circuitry to use a first weight value to weight operating system priority information to generate a first weighted priority value, second circuitry to use a second weight value to weight system-on-chip (SoC) hardware priority information to generate a second weighted priority value, third circuitry to sum the first weighted priority value and the second weighted priority value to generate a quality of service (QoS) value for an SoC interconnect transaction, and an arbiter to use the QoS value to prioritize the SoC interconnect transaction on an SoC interconnect.

Dynamic prioritization of system-on-chip interconnect traffic using information from an operating system and hardware

A communication device and method adapted for network data decoding and connection modes switching in a mobile communication system consisting of connecting to a network in a first mode comprising decoding data received from the network; receiving a message from the network; transmitting a negative acknowledgement (NACK) for the message to the network; identifying a retransmission of the message from the network; and switching to a second mode comprising skipping data decoding based on the identified retransmission of the message from the network.

Communication device and method for decoding data from a network

Aspects of the present disclosure provide methods and apparatus for offloading checksum processing in a user equipment (UE) (e.g., from an application processor to a modem processor). Such offloading may speed up packet processing, increase data rate, and/or free up resources of the application processor for other tasks.

Methods and apparatus for offloading checksum processing

Managing of secondary carriers for a multicarrier user equipment (UE) is described in which the UE initiates or provides input for activation and deactivation of selected secondary cells in a carrier aggregation depending on allocation or provisioning of UE radio frequency resources.

UE-initiated dynamic activation and de-activation of secondary carriers

Systems and methodologies are described herein that facilitate efficient transfer of quality of service (QoS) context during inter-radio access technology (RAT) handovers. In particular, techniques are described herein for establishing rules for whether a user equipment unit (UE) or an associated network should establish QoS for a mixed-mode application, identifying flow to bearer mappings when translating QoS across an inter-RAT handover, mapping QoS parameters of respective RATs, mitigating QoS depreciation upon multiple handovers, performing one or more actions if QoS is not acceptable in a new RAT, maintaining QoS during tunnel mode, and handling scenarios in which a UE moves between a RAT using network-initiated QoS and a RAT using UE-initiated QoS.

Method and apparatus for QoS context transfer during inter radio access technology handover in a wireless communication system

Aspects of the present disclosure generally relate to wireless communication and to mechanisms designed to help improve dynamic sharing of one or more receive chains among different radio access technologies (RATs). For example, the mechanisms may be used with LTE and other RATs where Carrier Aggregation is used for simultaneous voice and LTE (SV-LTE) applications.

Mechanism to improve dynamic sharing of receive chain(s) among radio access technologies

Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times&#x2014;based upon the comparison&#x2014;then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.

Protocol data unit recovery

An access terminal pre-registers with a second access network via a first access network to ensure a quick handover in the future. Frequent pre-registration attempts are avoided by implementing a hysteresis timer that restricts when a pre-registration process can be initiated. The hysteresis timer is started when pre-registration is initiated by the access terminal. No new pre-registration attempts are permitted if the hysteresis timer has not expired. An abort condition can cause the hysteresis timer to be aborted early, and a new pre-registration can be initiated. Access points in the first access network may be grouped into one or more pre-registration zones. If the access terminal moves from a first access point to a second access point, a new pre-registration is skipped if the first and second access points have the same pre-registration zone or the second access point is aware of the pre-registration zone for the first access point.

Method and apparatus for reducing successive pre-registration attempts by access terminals

Certain aspects of the present disclosure propose techniques for independently signaling features supported by a user equipment (UE) in different duplexing modes. The UE may be capable of communicating in frequency division duplexing (FDD) and time division duplexing (TDD) modes. The UE may obtain a FDD-specific feature group indicators (FGIs) set and a TDD-specific FGIs set, and signal at least one of the FDD-specific FGIs set or TDD-specific FGIs set. In addition, the UE may take one or more actions to reduce the likelihood of transitioning to a mode of operation that is different from its current mode of operation.

Methods and apparatus for employing different capabilities for different duplexing modes

Certain aspects of the present disclosure propose a method for domain selection in a multimode UE. The domain selection method may be used to select domains for short message service (SMS) and/or voice service when the UE has camped on a packet switched (PS) network such as LTE. The proposed domain selection method may take into account UE capabilities, home operator preferences, visited operator preferences, visited network capabilities, and user settings.

System, apparatus, and method to enable domain selection in a multimode device

Methods and apparatus are provided for device configuration (e.g., feature segment loading and system selection). Certain aspects of the present disclosure generally relate to operating a user equipment (UE) in a first radio access network (RAN) with a first set of modem features that supports the first RAN, detecting a second RAN not supported by the first set of modem features, and rebooting the modem software to load a second set of modem features that supports the detected RAN. For certain aspects, the first RAN may be a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network and the second RAN may be a Wideband-Code Division Multiple Access (W-CDMA) network or long term evolution network. This allows features to be loaded into memory (e.g., only) when they are required to support a detected RAN, rather than loading an entire image, thereby conserving DRAM and increasing efficiency.

Methods and apparatus for updating a device configuration

Disclosed are methods and apparatus for improving the performance of a user equipment handover during a data call. In one aspect, a source base station determines to handover user equipment (UE) to a target base station. The source base station first determines whether the UE is in a data call prior to the handover. The source base station then modifies one or more of connected mode discontinuous reception (CDRX) and semi-persistent scheduling (SPS) parameters with the UE based on determining to handover the UE and determining that the UE is in the data call.

Apparatus and method for improving device handover during a call

Certain aspects of the present disclosure relate to techniques for improving a circuit-switched fallback (CSFB) user experience. In aspects, methods and systems for autonomously returning a user equipment (UE) from a 2G (2generation)/3G (3generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE, in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g., from the status of the flag), may trigger a mobility mechanism to autonomously return the UE to the LTE network.

Methods and apparatus for improving a call fallback user experience

Certain aspects of the present disclosure relate to methods and apparatus for improving data service availability. Certain aspects provide methods and apparatus for wireless communications by a UE including determining, while the UE is in a coverage area of a first network, that a connection to a second network, comprising a packet data network (PDN), is disconnected locally, and taking at least one action to avoid a rejection of a request to connect to the second network.
