Abstract: This disclosure relates to techniques for multi-RAT and DSDA capable wireless devices to handle frame blanking in a wireless communication system. A wireless device may establish wireless links according to a first radio access technology and a second radio access technology. The wireless device may determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first radio access technology to perform sounding reference signal transmissions for the second radio access technology based at least in part on a band combination for the wireless links. The wireless device may determine a modification to channel state feedback reporting for the first radio access technology based at least in part on the transmit and receive blanking. The wireless device may perform channel state feedback reporting using the determined modification.

Abstract: Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.

Abstract: A mobile device receives an invitation to commence a media session. The invitation may be from a legitimate caller or from a spoofing caller. The mobile device checks parameters using templates to evaluate a consistency of the invitation with respect to a database in the mobile device. The templates include session protocol, network topology, routing, and social templates. Specific template data includes standardized protocol parameters, values from a database of the mobile device and phonebook entries of the mobile device. Examples of the parameters include capabilities, preconditions, vendor equipment identifiers, a hop counter value and originating network information. The originating network information may be obtained from the database by first querying an on-line database to determine a network identifier associated with caller identification information in the invitation. Then, the obtained carrier identifier is used as an index into a database to obtain template data characteristic of the identified originating network.

Abstract: The disclosed embodiments provide a system that processes network packets. Upon receiving a first Transmission Control Protocol (TCP) header for a first TCP segment from a network link, the system immediately provides a portion of the first TCP header to a transport layer prior to receiving all payload data for the first TCP segment. Next, the system uses the transport layer to transmit a first acknowledgment of the first TCP segment to the network link, wherein the first acknowledgment reduces a round-trip time (RTT) associated with the first TCP segment.

Abstract: User equipment includes a first antenna, a second antenna, a first transceiver coupled to the first antenna, a second transceiver coupled to the second antenna, and processing circuitry communicatively coupled to the first transceiver and the second transceiver. The first transceiver receives or transmits a first signal via the first antenna, and the second transceiver receives or transmits a second signal via the second antenna. The processing circuitry receives an indication that a signal characteristic of the first signal is less than a first threshold, and decreases power to the first antenna, the first receiver, or both, based on the signal characteristic of the first signal being less than the first threshold.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively provide enhanced the quality of service (QoS) for an application. The UE may request a dedicated bearer or flow for communications conducted over a network between a UE application and a server associated with the application. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or determine whether to provide the enhanced QoS functionality, e.g., whether to request the dedicated bearer/flow from the network. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.

Abstract: Apparatus and methods to support parallel communication using multiple subscriber identities in a wireless communication device via multiple subscriber identity modules (SIMs) are disclosed. A representative method includes establishing a connection with a first wireless network via a first wireless cellular protocol software stack for a first subscriber identity associated with a first subscriber identity module; registering with a second wireless network via a second wireless cellular protocol software stack for a second subscriber identity associated with a second subscriber identity module; and receiving radio frequency signals from the second wireless network via the second wireless cellular protocol software stack in parallel with communicating with the first wireless network via the first wireless cellular protocol software stack. The first and second wireless cellular protocol software stacks share at least a portion of radio frequency wireless circuitry for communicating with the first and second wireless network respectively.

Abstract: In embodiments, a client station operates to identify and prioritize time-sensitive short-range wireless packets, such as time-sensitive Bluetooth Low Energy (BTLE) packets, in a congested wireless environment. The client station may identify time-sensitive packets using, e.g., the type of device providing the packets, a state of the device providing the packets, and/or the type of data included in the packets. The client station may prioritize the time-sensitive packets in various ways, including by providing priority scheduling to the time-sensitive packets; pausing communication of other types of Bluetooth packets, such as A2DP packets; reducing a data rate of other types of Bluetooth packets, such as A2DP packets; and/or extending a data packet size of time-sensitive BTLE packets. The time-sensitive packets may thus be prioritized over packets associated with the same wireless protocol and/or a different wireless protocol.
