  • Patent number: 10341081
    Abstract: A user equipment (UE) comprises a radio having TX and RX paths that include a duplexer, thus facilitating a full-duplex mode. The radio may also have TX and RX paths that exclude the duplexer, and which thus facilitate a half-duplex mode. The UE may be configured to autonomously and opportunistically switch from the full-duplex mode (the paths that include the duplexer) to the half-duplex mode (the paths that exclude the duplexer) when the UE desires to avoid the path loss caused by the duplexer, e.g., to temporarily receive with greater sensitivity and/or transmit with more power, during poor channel conditions. At other times the UE may autonomously decide to remain in full-duplex mode to achieve reduced transmission time, e.g., during time-critical communications such as VoLTE. The UE may autonomously determine whether to use full or half-duplex mode, i.e., without requiring any coordination with network-side devices.

  • Patent number: 9876624
    Abstract: For aperiodic reporting of CSI, nCQI ref is four, and a subframe n?nCQI ref corresponds to a valid subframe. A subframe that satisfies a criteria including at least a criterion (i) is regarded as being valid. In the criterion (i), in a case where third information for a radio frame is detected, an UL-DL configuration for the radio frame is given by the third information for the radio frame, and in a case where the third information for the radio frame is not detected, the UL-DL configuration for the radio frame is given by first information. The criterion (i) stipulates that the subframe is a subframe indicated as a DL subframe or a special subframe by the UL-DL configuration for the radio frame. In a case where a subframe n?4 is not a valid subframe for aperiodic reporting of channel state information, the reporting of the CSI is omitted in the subframe n.

    Abstract: Systems and methods for application profiles and device classes in power line communications (PLCs) are described. In some embodiments, a PLC device has the device class defined by a PHY layer and may include a processor and a memory coupled to the processor. The memory may be configured to store program instructions, which may be executable by the processor to cause the PLC device to communicate with a higher-level PLC apparatus over a power line using a frequency band. The frequency band may be selected based upon an application profile and/or a device class associated with the PLC device. In some implementations, the higher-level PLC apparatus may include a PLC gateway or a data concentrator, and the PLC device may include a PLC modem or the like. Examples of application profiles include access communications, in-premises connectivity, AC charging, and/or DC charging. Device classes may represent a minimum communication data rate and/or an operating frequency band restriction of the PLC device.
