Abstract: A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

Abstract: Systems and methods for reducing collisions of transmission data for a first subscriber (e.g., a voice subscriber) with transmission data for a second subscriber (e.g., a data subscriber) at a dual sim dual active (DSDA) user equipment (UE) are described herein. A DSDA UE may be configured to implement a modified skipUplinkTxDynamic feature that avoids collisions by buffering transmission data of the data subscriber and sending a (later) scheduling request (SR) for a grant for that data. A DSDA UE may regulate data subscriber transmissions to avoid a transmission duration for the voice subscriber. A DSDA UE may reduce certain transmissions for a voice subscriber (subject to a block error rate (BLER) threshold for the voice subscriber) to lower the probability of collision. A DSDA UE may operate a data subscriber and a voice subscriber in the same cell to avoid collisions due to RF tuning and/or relative slot overlap.

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: This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6 GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

Abstract: Techniques are disclosed relating to a mobile device that initiates handovers from short-range networks to long-range networks. In various embodiments, a mobile device includes one or more radios that communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. In such an embodiment, the mobile device stores an indication that the cellular RAT is a preferred RAT for a communication session. The mobile may establish the communication session using the preferred RAT, and in response to determining that a quality of the preferred RAT fails to satisfy a set of quality criteria, may request that the communication session use the short-range RAT. In some embodiments, the mobile device analyzes average packet error rate for the communication session and in response to the average packet error rate satisfying a threshold, requests that the communication session use the cellular RAT.

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: Embodiments relate to apparatus, systems, and methods for reception of calls on a mobile device that includes Wi-Fi and cellular radios. The mobile device may be configured to establish communication on a Wi-Fi network with a cellular carrier. The mobile device may further be configured to register a first IP address with an IMS server for the Wi-Fi network communication and register a second IP address with the IMS server for the cellular network communication (or register different ports of a single IP address with Wi-Fi and cellular). Upon occurrence of a mobile terminating call from the cellular carrier, the mobile device may receive an incoming call notification on one or both of the Wi-Fi network using the first IP address and the cellular network using the second IP address.
