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.

Abstract: Systems, methods, and devices for operating in either frequency division duplexing (FDD) or time division duplexing (TDD) for wireless communications using the same electrical balance duplexer (EBD) circuitry in a transceiver device are provided. A series of switches may selectively couple components of the EBD, such as a low noise amplifier (LNA), a power amplifier (PA), and balancing impedance, to ground based on selected operation mode (e.g., FDD or TDD) while reducing insertion loss of the receiver (RX) and transmitter (TX) signals. Tuned matching network blocks for the LNA and PA may be used in addition to the series of switches to provide impedance matching for additional reduction of insertion loss.

Abstract: This disclosure relates to techniques for supporting narrowband device-to-device wireless communication, including possible techniques for performing discovery in an off grid radio system. A wireless device may obtain synchronization with a peer-to-peer communication group. The wireless device may determine the location of the wireless device within the peer-to-peer communication group based at least in part on signal strength of a synchronization signal used to obtain the synchronization. The wireless device may perform peer-to-peer discovery in the peer-to-peer communication group, such that time and frequency resources used by the wireless device to perform the peer-to-peer discovery are determined based at least in part on the location of the first wireless device within the peer-to-peer communication group.

Abstract: This disclosure relates to techniques for supporting narrowband device-to-device wireless communication, including possible techniques for performing control and data communications between wireless devices that have performed discovery. A first device may transmit first control information to a second wireless device. The first control information may indicate a buffer status of the first wireless device. The first device may receive second control information from the second wireless device. The second control information may include an acknowledgement indication for the first control information. The first device may transmit a data communication to the second wireless device based at least in part on the first control information and the second control information.

Abstract: Systems, methods, and devices are provided for reducing and/or eliminating impact of inter-carrier interference on wireless signals transmitted and received via off-grid radio communications (e.g., Device-to-Device (D2D) communication). The method may include using circuitry to generate a plurality of subcarriers associated with a data signal, such that the plurality of subcarriers transmit the data signal along a narrowband transmission channel. The method may involve using the circuitry to remove a null subcarrier of the plurality of subcarriers that is located at a direct current (DC) frequency. The method may also involve generating an asymmetrical frequency spectrum for a portion of the plurality of subcarriers centered about the removed null subcarrier. The method may also include transmitting the plurality of subcarriers to another electronic device via D2D communication.
