Abstract
Methods and apparatus are provided for integrated communication and sensing. For example, an electronic device may transmit a radio frequency (RF) pulse signal in the active phase of a periodic sensing cycle, and sense in the passive phase of the sensing cycle, a reflection of the RF pulse signal reflected from an object. The RF pulse signal is defined by a waveform for carrying communication data between electronic devices. The sensed RF pulse signal is at least a portion of the transmitted or reflected RF pulse signal, wherein the portion is equal to or greater than a threshold value for the object being within a sensing range of the first electronic device. The electronic device may also receive a communication signal from another electronic device during the passive phase.
