Abstract: A wireless device may determine the level of interference mitigation appropriate for the application and dynamically select a combination of interference cancellation components that satisfies that level. The combination of interference cancellation components may include components that consume power (e.g., active components) and components that do not consume power (e.g., passive components). The interference cancellation components may be used at the transmitter and/or the receiver. In some cases, the wireless device may also determine how much power is acceptable to expend on the interference mitigation. In such scenarios, the selection of the interference cancellation components may be such that the aggregated power consumption is less than the power expenditure limit.

Abstract: Systems and methods are disclosed for enhancing the power efficiency of low power internet of everything (IOE) devices or user equipments (UEs). A UE or IOE having a low power companion receiver maintains its full power receiver in a sleep state until it receives a wake up indicator from a base station. In response to the wake up signal, the UE or IOE powers up its full power receiver and receives data from the base station. The base station further schedules the wake up signals so as not to collide with control signals expected by UEs or IOEs without low power receivers, or those UEs and IOEs are configured to detect and react to the wake up signals.

Abstract: When embedding a signal into a selected subcarrier of a multicarrier downlink waveform of regular data/control signaling, a base station modulates the embedded signal with a different modulation scheme than the other data in the downlink waveform. The base station nulls adjacent subcarriers to minimize interference at a low-power wake-up receiver of an IOE device(s). The IOE device wakes up the low-power wake-up receiver at scheduled times to listen for the signal. For synchronization signals, the IOE device corrects a local clock based on a correlation value of the signal to a predetermined sequence. For wake-up signals, the IOE device correlates whatever is detected at the antenna to a predetermined sequence and compares the correlation value to a predetermined threshold. If the threshold is met, the IOE device registers a wake-up signal and wakes the primary transceiver of the device. If not, the receiver goes back to sleep.

Abstract: A device may use enhanced power amplifier (PA) linearization techniques such as adaptive feed-forward (FF) linearization using adaptive filters. In one example, an adaptive feed-forward linearizer may isolate a distortion signal based at least in part on the signals input to and output from a PA in a transmission path. The distortion signal may be used to cancel distortion at the output of the PA to produce an improved output signal. A first adaptive circuit may be used to produce the distortion signal and a second adaptive circuit may be used to produce an error cancellation signal based at least in part on the distortion signal. The error cancellation signal may be amplified and re-introduced to the transmission path to produce the improved output signal. Semi-adaptive circuits may be used in place of the adaptive circuits, or a hybrid approach may be used.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support two different modes of operation (e.g., a normal transmission efficiency mode, a high transmission efficiency mode, etc.) either controlled by a network or the UE. The UE may transmit an indication of a capability of supporting the different modes of operation, where the network or the UE determine to use which mode of operation to use based on the transmitted capability. For example, the network may transmit an explicit indication of which mode of operation for the UE to use and/or may transmit an indication of the modes of operation, where the UE determines which mode of operation to use after receiving the indication. Additionally, the UE may determine which mode of operation to use based on being scheduled within or outside of a restricted bandwidth allocated to a mode of operation.
