Devices and methods for facilitating a non-orthogonal underlay in wireless communications systems

Abstract:

Wireless communication devices are adapted to facilitate non-orthogonal underlay transmissions. In one example, devices can receive a wireless transmission on a particular time and frequency resource including a first signal from a first wireless device and a second signal from a second wireless device. The first signal may utilize a first type of modulation for orthogonal wireless communication, and the second signal may utilize a second type of modulation non-orthogonal to the first type of modulation. The wireless communication device can decode the first and second signals. In another example, devices may transmit a first signal utilizing a first type of modulation over a time and frequency resource scheduled for a second signal from a second wireless communication device, the second signal utilizing a second type of modulation for orthogonal wireless communication, where the first type of modulation is non-orthogonal with the second type of modulation. Other aspects, embodiments, and features are also included.
