An electronic device may be provided that includes a first processor and a second processor, the first processor to wirelessly receive a data packet from another device, and to determine a property (or type) of the received data packet. When the property or type of the received data packet is a first property or first type then the first processor to process the data packet. On the other hand, when the property or type of the received data packet is a second property or second type then the second processor to process the data packet.

A low power wake on radio circuit detects if an RF signal is present on an input to the wake on radio circuit. An RF sense circuit supplies an RF sense signal indicating whether the RF signal is present on the input. The RF sense signal is used to incrementally turn on digital decode logic to determine if a radio transmission that is unique to the wake on radio circuit has been received. If the unique radio transmission have been received, the wake on radio circuit supplies a wakeup signal to the rest of the system.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support dynamic clock switching within a transmission time interval (TTI) to allow for more efficient and flexible processing within the TTI. In particular, a user equipment (UE) may be configured to use multiple clock speeds for processing signals within a TTI, and the UE may determine a clock speed to use for processing data within a TTI based on control information received from a base station. For example, the UE may determine an amount of time available for processing data based on the control information received from the base station, and the UE may adjust its clock speed to finish processing the data in the determined amount of time.

This document describes techniques (400, 500, 600) and apparatuses (100, 700) for implementing sensor-based near-field communication (NFC) authentication.
