Abstract: A user equipment (UE) determines a transmission power for data transmission to a network. The UE determines a specific absorption rate (SAR) limit associated with the UE and determines a transmission power to be allocated to data transmissions based on one or more applications running on the UE and the SAR limit.

Abstract: Methods, apparatuses and computer readable media are described that configure wireless circuitry of a wireless communication device. The wireless communication device establishes a connection to a first wireless network using first and second receiving signaling chains. In response to detecting a radio frequency tune-away event, the wireless communication device reconfigures only one of the radio frequency signaling chains to receive signals from a second wireless network when a set of receive signal conditions for the second wireless network is satisfied. The wireless communication device reconfigures both of the radio frequency signaling chains to the second wireless network when the set of receive signal conditions is not satisfied.

Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

Abstract: A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

Abstract: Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

Abstract: Systems and methods provide secondary cell group (SCG) activation and deactivation. A user equipment (UE) in a wireless network may determine bandwidth part (BWP) configurations for a carrier of a primary secondary cell (PSCell) of an SCG for dual connectivity (DC). The UE may move between an SCG activation state and an SCG deactivation state based on the BWP configurations. SCG deactivation modeling may be based on a separate BWP configuration or may be modeled via a separate configuration in radio resource control (RRC) that is applicable to the BWPs in a serving cell.

Abstract: Embodiments described herein relate to dynamic selection of radio access technologies (RATs) available for use by 5G wireless devices. Managing selection of RATs to use by a 5G (and 4G LTE) capable wireless device can improve performance, e.g., when an application requires a higher throughput and a 5G SA connection underperforms a 5G NSA connection or a 4G LTE connection. Wireless devices can provide geolocation tagged cellular wireless network information, e.g., network performance measurements and observed properties, to network-based servers that collate and organize the crowd-sourced cellular wireless network information into a location database. The wireless device can use the cellular wireless network information of the location database for a geolocation at which the wireless device is operating to estimate performance for alternate wireless connections and compare to measured performance of a currently used wireless connection to determine whether to switch wireless RAT connections.

Abstract: A method performed by a station that includes receiving information from a cell of a Public Land Mobile Network (PLMN), determining whether the information indicates the cell supports circuit switched fallback (CSFB) voice calls, when the CSFB voice calls are not supported, determining whether at least one packet switched voice property of the station satisfies a predetermined condition and attaching to the cell of the PLMN when the predetermined condition is satisfied. A further method performed by a station connected to a PLMN that includes identifying cells of the PLMN available for the station to camp on, determining whether the station is capable of executing packet switched calls, when the station is not capable of executing packet switched calls, determining whether the identified cells have a neighbor cell that supports CSFB voice calls and prioritizing the cells that are identified as having neighbor cells that support CSFB voice calls.
