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 a link budget limited UE to improve communications performance with a cellular network. The UE may perform signal to interference noise ratio (SINR) measurements and use these measurements to adjust a received signal power value that is provided to the cellular network as a received signal power measurement. The UE may generate the received signal power value based at least in part on the SINR measurement in order to reduce the likelihood of handover when the UE has good SINR but poor received signal power. The UE may also provide preferred configuration information to the base station which enhances the performance of the UE when link budget limited. The configuration information may specify one or more parameter values designed to provide improved performance for a link budget limited device.

Abstract: This disclosure relates to transmitting an emergency message to a user equipment device (UE) over a wireless local area network (WLAN).

The UE may transmit, via the access point and to a network entity, an indication that the UE supports receiving emergency messaging through the WLAN. At least in part in response to communicating the indication, the UE may receive, from the network entity and via the access point, an emergency message and location information. The UE may compare the location information with a location of the UE to determine whether the UE is located within a first region specified by the location information. Based on a determination that the location of the UE is within the first region, the UE may display the emergency message on a display of the UE.

Abstract: This disclosure relates to using a dedicated reference subframes in a cellular communication system. According to one embodiment, a base station may transmit reference signals in a dedicated synchronization and measurement reference subframe. Neighboring base stations may also transmit reference signals in dedicated reference subframes in a temporally coordinated (synchronized) manner. The reference signals transmitted be each base station may be orthogonal with the reference signals transmitted by each neighboring base station. The reference subframes may be transmitted periodically, and data subframes may be transmitted between reference subframes. Some or all of the data subframes may not include cell-specific reference symbols, as their function may be unnecessary given the use of the dedicated reference subframes.
