Abstract: Techniques discussed herein can facilitate power management at a User Equipment (UE) via selection of a power management stage based on a current power status. One example aspect is a UE comprising one or more processors configured to: monitor a temperature of the UE via one or more temperature sensors and a power usage of the UE; determine a power status of the UE based at least in part on the temperature of the UE and the power usage of the UE; select, based at least in part on the determined power status, a power management stage of a plurality of power management stages; and implement one or more power management techniques associated with the selected power management stage. A notification can be triggered to alert a user that the processor is implementing the one or more power management techniques prior to implementation.

Abstract: A device, e.g. a wireless communication device may obtain information associated with private cellular networks from a provisioning server. The information may provide an indication of coverage area(s) of available private cellular network(s). The device may communicate over a commercial cellular network, and determine, based at least on the information, whether the device is located within the coverage area of any available private cellular networks. The device may connect to a first private cellular network (FPCN) of the available private cellular networks and switch from communicating over the commercial cellular network to communicating over the FPCN at least in response to the determination indicating that the device is located within the indicated coverage area. The device may disconnect from the FPCN in response to a determination that the signal level of the FPCN is below a specified value and the device is not using a wallet garden application.

Abstract: This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit a master information block (MIB), a first system information block (SIB), and second SIBs. The first SIB and the second SIBs may be configured for different device categories, and may accordingly have different characteristics. For example, the first SIB may be configured for link budget limited devices, and may include information specific to such devices and/or may exclude information not relevant to such devices or not critical to accessing the cell. In some instances, the first SIB may also include information from the MIB, such that at least some devices may be able to decode the first SIB and gain cell access without decoding the MIB.

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 establish a connection with an access point through 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: An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.

Abstract: A circuit component may determine whether first signal indicative of at least one of the plurality of communication interface circuits accessing the FEM during a respective communication slot associated with the FEM has been received, determine a first Received Signal Strength Indicator (RSSI) value for the respective communication slot used by the FEM based on data associated with the respective communication slot, and store the first RSSI value in response to the first signal not being received. The circuit component may then determine a first gain for a subsequent slot based on the first RSSI value and discard the first RSSI value in response to the first signal being received.

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.
