Abstract: An apparatus such as a wireless communication device (UE) may include first circuitry configured to conduct wireless communications according to a first radio access technology (RAT) in a first frequency band and in a second frequency band, where the first RAT is a cellular RAT, the first frequency band is in an unlicensed spectrum, and the second frequency band is in a licensed spectrum. The apparatus may include second circuitry configured to conduct wireless communications according to a second RAT in the first frequency band, wherein the second RAT is a wireless local area network (WLAN) RAT. The apparatus may be configured to determine to perform a scan operation in the first frequency band using the first circuitry and, based on one or more transmissions by the second circuitry using the first frequency band, adjust one or more parameters for the scan measurement by the first circuitry. The cellular communications in the first frequency band may be LAA communications, for example.

Abstract: A low-power scouting receiver is presented that provides an ability perform low-power scouting functions at a relatively low power. The low-power scouting functions determine context information for the receiver and enable fine-tuning of other receiver operations based on the context information. The low-power scouting functions include receiver control and switching, jammer detection, self-interference detection, or other context-dependent radio parameters.

Abstract: A wireless device, such as a user equipment device (UE), and a base station are disclosed, which may communicate with more efficient use of dynamic transmit time interval durations to enable a faster and more efficient ramp up of TCP communications to a higher or maximum throughput. The UE may communicate uplink or downlink communications with the base station according to a first shorter TTI duration for a first period of time. After the first period of time, the UE may communicate uplink or downlink communications to the base station according to a second longer TTI duration. For the case of uplink communications, the UE may be configured to increase a congestion window size after each acknowledgement of an uplink communication received by the base station during the first period of time. For the case of downlink communications, the base station may be configured to increase a congestion window size after each acknowledgement of a downlink communication received by the UE during the first period of time.

Abstract: Embodiments relate to coordinating the operations of subsystems in a communication system of an electronic device where a coexistence hub device monitors the state information transmitted as coexistence messages over one or more multi-drop buses, processes the monitored coexistence messages and sends out control messages as coexistence messages to other systems on chips (SOCs). The coexistence hub device can also update the operations of the communication system. The coexistence hub device may receive an operation policy from a central processor and may execute the operation policy without further coordination of the central processor. The coexistence hub device broadcasts the control messages as coexistence messages according to the executed operation policy.

Abstract: A user equipment (UE) device may communicate according to a new device category satisfying specified QoS (quality of service) requirements while also satisfying specified link budget requirements, and/or additional optimization requirements. The UE device may communicate with a cellular base station according to a first mode of operation associated with the new device category, and may switch to communicating with the cellular base station according to a second mode of operation associated with a second (pre-existing) device category in response to the link budget requirements exceeding a specified value and the quality of service requirements not being sensitive. The UE device may also switch to communicating with the cellular base station according to a third mode of operation associated with a third (pre-existing) device type in response to the link budget requirement not exceeding the specified value, or the QoS requirements being sensitive and a downlink throughput requirement exceeding a specified throughput value.
