    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: This disclosure relates to techniques for providing robust downlink control information with flexible resource assignments for wireless devices that operate in a restricted bandwidth compared to the system bandwidth. A base station may determine a resource assignment for a wireless device. The base station may transmit downlink control information to the wireless device. The downlink control information may include an indication of a resource assignment for the wireless device. The indication of the resource assignment may include an indication of a first narrowband associated with the resource assignment, and an indication of whether one or more additional narrowbands are associated with the resource assignment. The base station and the wireless device may communicate data according to the resource assignment.

    Abstract: Techniques are disclosed relating to a mobile device that communicates over short-range networks and long-range networks. In various embodiments, a mobile device includes one or more radios configured to communicate using a plurality of radio access technologies (RATs) including a cellular RAT and a short-range RAT. The mobile device may establish a first connection and a second connection with a network such that the first connection uses the short-range RAT and the second connection uses the cellular RAT. The mobile may collect information about the second connection and communicate the collected information to the network over the first connection. In some embodiments, the information includes a base station identifier, an MCC, an MNC, the cellular RAT and a cellular information age indicating the time since the information about the second connection was collected by the UE.

    Abstract: Methods and apparatus for using an unlicensed radio frequency band component carrier for uplink transmission are disclosed. A wireless communication device receives a carrier aggregation configuration, which can include at least one licensed radio frequency band component carrier and at least one unlicensed radio frequency band component carrier. The wireless communication device establishes a set of radio bearers and associates an unlicensed radio frequency band permission level with each of the radio bearers. The wireless communication device multiplexes uplink traffic for the radio bearers on the at least one licensed radio frequency band component carrier and the at least one unlicensed radio frequency band component carrier based at least in part on the unlicensed radio frequency band permission levels associated with the radio bearers.

    Abstract: This disclosure relates to use of WLAN virtual interfaces. According to one embodiment, a wireless device may be capable of using a WLAN chipset for user initiated WLAN communication and for cellular offloading WLAN communication. A separate WLAN virtual interface may be established for each type of WLAN communication, including a first WLAN virtual interface between the WLAN chipset and a WLAN connectivity manager executing on an application processor of the wireless device and a second WLAN virtual interface between the WLAN chipset and a cellular connectivity manager executing on the application processor. The virtual interfaces may each use a different IP address, and may either multiplex data onto a shared RF chain in a time-sharing manner or each be provided with their own RF chain to perform WLAN communication.
