Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: This disclosure relates to techniques for supporting cross functional signaling for device-to-device wireless communication, such as an off grid radio system. According to some embodiments, a first wireless device may initiate, modify, and/or close a device-to-device wireless communication session with a second wireless device using session management signaling associated with a protocol layer (possibly a higher layer, such as a layer supported by an application processor) of the first wireless device. The wireless device may provide indications of session initiation, modification, and/or closing from the protocol layer used to exchange the session management signaling to another protocol layer (possibly a lower layer, such as a layer supported by a baseband processor) of the first wireless device.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: A network controller, a user equipment (UE) device, and associated methods for conducting intelligent enhanced multimedia broadcast multicast services (eMBMS). A network controller receives user preference information and location information from a plurality of UEs. The network controller selects one or more data packages to transmit using eMBMS in one or more broadcast regions based on the user preference information and the location information. The one or more data packages may comprise an updated machine learning model in a distributed learning application. The network controller provides an indication to a remote device to broadcast the one or more data packages in the respective one or more broadcast regions using eMBMS.

Abstract: This disclosure relates to techniques for supporting narrowband device-to-device (D2D) wireless communication, including possible techniques for providing synchronization and master information block signals in an off grid radio system. A wireless device may provide D2D synchronization signals for a D2D communication group. The D2D synchronization signals may be provided using multiple frequency channels. The D2D synchronization signals may be provided on each respective frequency channel of the frequency channels during a respective portion of a D2D synchronization signal cycle in a sequential manner.

Abstract: Apparatuses, systems, and methods for a wireless device to detect intermodulation issues and configure a transmission scheme to remedy detected intermodulation issues. The wireless device may perform measurements on a downlink carrier while one uplink carrier is scheduled for the wireless device. The wireless device may also perform measurements on the downlink carrier while two uplink carriers are scheduled for the wireless device. The wireless device may provide information based on those measurements to a serving base station. The base station may determine that an intermodulation issue is occurring at the wireless device based on the information provided, and may configure the wireless device to use a single uplink carrier at a time based at least in part on the intermodulation issue.

Abstract: Apparatuses, systems, and methods for a wireless device to manage an uplink bearer that utilizes concurrent inter-RAT dual uplink connectivity to avoid packet loss during bearer switch, handover, and/or radio link failure occasions. The wireless device may establish a first wireless link according to a first radio access technology (RAT) and a second wireless link according to a second RAT. A data bearer may be established that utilizes both the first wireless link and the second wireless link. Uplink data packets of the data bearer that are provided to a protocol stack for the second RAT may be stored in a buffer. The second wireless link may be lost. The stored uplink data packets that were provided to the protocol stack for the second RAT may be provided to a protocol stack for the first RAT based at least in part on the second wireless link being lost.

Abstract: An interface circuit in an electronic device (such as an access point) may provide a group wake-up packet to a group of recipient electronic devices in a set of recipient electronic devices. During operation, the interface circuit may select the group in the set of recipient electronic devices, where the group includes at least one of the recipient electronic devices. Then, the interface circuit may provide the group wake-up packet for the recipient electronic devices in the group with information that specifies that a subset of the recipient electronic devices in the group transition from a low-power mode. For example, the information may include a bitmap that specifies the subset and an identifier of the group. Note that the electronic device may dynamically define the group. Alternatively, the recipient electronic devices in the group may be static.

Abstract: Apparatuses, systems, and methods to perform attachment of a wireless device to substantially concurrent connections with a next generation network node and a legacy network node. The wireless device may be configured to transmit a request to attach to a first network node operating according to the first RAT and transmit an indication that the wireless device is capable of maintaining substantially concurrent connections with the first network node and a second network node that operates according to the second RAT. The wireless device may also be configured transmit a request to attach to the second network node. The request may include an indication that the wireless device is capable of maintaining substantially concurrent connections with the first and second network nodes. Further, the wireless device may be configured to receive an indication that dual connectivity with the first and second network nodes has been established.
