Abstract: A wireless communication device (UE) may conduct wireless communications using one or more antennas according to multiple radio access technologies (RAT) associated with corresponding operating frequency bands. The UE may perform adaptive antenna tuning, for example, application-based antenna tuning for increasing the operating efficiency of the UE, which may improve user experience. The UE may periodically identify one or more applications running on the UE, the respective RATs that support the (running) applications, and which of the corresponding frequency bands are used by the (running) applications. The UE may determine the tuner device settings for tuning the one or more antenna(s) based on the (running) applications or the type and/or priority of the (running) applications, which RATs support the running applications, which of the corresponding frequency bands are used by the (running) applications, and operating conditions associated with the frequency bands used by the (running) applications.

Abstract: Disclosed are embodiments for reducing likelihood of selecting a cell identified by a Radio Access Network (RAN) Notification Area ID (RNA ID) that is different from that identifying a last or current serving cell so as to avoid an RNA update procedure; reducing Random Access Channel (RACH) transmissions for an RNA update procedure and a mobile originated (MO) data transmission in response to a Radio Resource Control (RRC) triggered RNA update procedure; and selecting a band or beam in a multi-band/beam cellular system that improves RACH efficiency.

Abstract: Systems and methods for extending connectivity with a cellular network are disclosed herein. A UE may monitor a serving cell of the UE and a neighbor cell of the UE to determine whether there is a network condition wherein the UE is to transition to an out-of-service (OOS) state if it were to fall to an Radio Resource Control (RRC) Idle state. The UE may react by, before expiration of an inactivity period corresponding to a transition to an RRC Idle mode, initiating signaling activity with a radio access network (RAN) node of the serving cell. In other embodiments, the UE may determine, based on a number of secondary devices connected to the UE, to initiate signaling with the RAN node of the serving cell before expiration of an inactivity period and according to whether a maximum number of extensions of an extension activity period has been reached.

Abstract: A user equipment (UE) may skip certain measurements when it is unlikely that the UE will use the measurements. The UE determines that the UE is configured with one of a measurement gap or gapless measurements, identifies that a predetermined condition has been satisfied and implements a mitigation technique in response to identifying that the predetermined condition has been satisfied, wherein the mitigation technique includes omitting performing one of a measurement during the measurement gap or a gapless measurement, wherein the measurement or the gapless measurement corresponds to a first radio access technology (RAT) that is different than a second RAT on which the UE is currently camped.

Abstract: Multi-radio wireless network devices are capable of transmitting and/or receiving data from multiple radiofrequency (RF) networks at different bands. Total transmission power limitations may be in place due to, for example, safety reasons. As a result, active management of transmission power may be performed during simultaneous transmission in different bands and/or networks. In some embodiments, the management may take place on group-by-group basis and a network-by-network basis. Antennas may be grouped based on their relative positions and impact on radiation emitted by the devices.

Abstract: Apparatuses, systems, and methods for enhancement of Wi-Fi calling for DSDS user equipment devices (UEs). The UE may register a first connection supported by a first SIM with IMS for VoWiFi based on a determination to prefer VoWiFi for the first SIM. The first SIM may be associated with a first subscription to a first RAN. The UE may include a second SIM that may be associated with a second subscription to a second RAN. The UE may register a second connection associated with the second SIM with the IMS for VoWiFi and/or VoLTE and initiate/receive, via the first connection supported by the first SIM, a VoWiFi call. A recommendation to handover the VoWiFi call from Wi-Fi to cellular data may be received and, based, at least in part, on the recommendation, the UE may register a second connection associated with the second SIM for IWLAN over cellular data.

Abstract: This disclosure relates to methods and devices for transmitting acknowledgment messages on a preferred cell in a carrier aggregation scenario. A user equipment device (UE) establishes a connection with a primary cell and one or more secondary cells, and determines a preferred cell from among the primary cell and the one or more secondary cells based at least in part on one or more quality metrics. The UE may determine the preferred cell at least in part in response to determining that transmission power of the UE has been limited due to a specific absorption rate (SAR) backoff feature of the UE. The UE transmits a notification to a network indicating that the UE intends to transmit an acknowledgement message to the preferred cell, and transmits the acknowledgment message to the preferred cell.

Abstract: A device, system and method for a user equipment (UE) to opportunistically utilize the wireless capabilities of a paired device. The UE is configured to establish a first cellular network connection based on a first subscription, a second cellular network connection based on a second subscription and a connection to a further UE based on a short-range communication protocol. The UE identifies a predetermined condition and transmits an indication to the further UE based on the predetermined condition. The further UE establishes a further cellular network connection in response to the indication and the further cellular network connection is based on one of the first subscription or the second subscription. The UE then declares no service for one of the first cellular network connection or the second cellular network connection based on the further cellular network connection.

Abstract: The present disclosure relates to opportunistically selecting an antenna in an electronic device having multiple antennas. A baseband processor of the electronic device may connect to a first cellular tower providing cellular service at a first frequency using a first antenna of the electronic device.

The baseband processor may determine signal measurements of the second cellular tower for each antenna of the electronic device that is capable of operating at the second frequency. The baseband processor may execute a handover to the second cellular tower using the antenna associated with the best performing signal measurements. In this manner, an antenna may be opportunistically selected based on performance of the antenna, improving operation of the electronic device and quality of cellular service.

Abstract: Described are on-die termination (ODT) systems and methods that facilitate high-speed communication between a driver die and a receiver die interconnected via one or more signal transmission lines. An ODT control system in accordance with one embodiment calibrates and maintains termination resistances and drive currents to produce optimal output swing voltages. Comparison circuitry employed to calibrate the reference resistance is also used to calibrate the drive current. Termination elements in some embodiments are divided into two adjustable resistive portions, both of which are designed to minimize capacitive loading. One portion is optimized to produce a relatively high range of adjustment, while the other is optimized for fine-tuning and glitch-free switching.
