Embodiment Construction

[0037] In this disclosure, the use of the terms "a," "an," or "the" is intended to include plural forms as well, unless the context clearly dictates otherwise. Also, as used in this disclosure, the terms "includes," "includes," "includes," "includes," "has," or "has" designate the presence of stated elements, but do not preclude the presence or addition of other elements .

[0038] Semi-Orthogonal Multiple Access (SOMA) refers to a communication technology that uses hierarchical modulation to simultaneously transmit information using different modulation layers. In some cases, different modulation layers may be assigned to different wireless devices.

[0039] In SOMA, a superimposed symbol constellation is formed from constituent constellations using various different modulation layers. The symbols of the superimposed symbol constellation include sub-symbols of the first modulation layer, sub-symbols of the second modulation layer, and so on. Subsymbols of different modulat...

Abstract

In some examples, the wireless device includes a network interface for communicating over the wireless network, at least one processor configured to transmit a capability information element including an indicator to indicate that the first wireless device supports the wireless network Semi-Orthogonal Multiple Access (SOMA) communication over the

Description

[0001] Cross-reference to related applications [0002] This application claims priority to US Patent Application Serial No. 16 / 241,254, filed January 7, 2019, entitled "Semi-Orthogonal Multiplex Communication and Acknowledgement of PPDUs," the entire contents of which are incorporated herein by reference . Background technique [0003] The goal of successive generations of radio frequency communication systems is to apply technologies that increase the amount of information transmitted using communication resources compared to the prior art. Semi-Orthogonal Multiple Access (SOMA) technology allows multiple wireless devices to use overlapping constellations to share wireless spectrum. A superimposed constellation of SOMA consists of constituent constellations using correspondingly different modulation layers. [0004] In a wireless network, wireless devices with different capabilities can be deployed. Wireless devices may include access points (APs) and other electronic dev...
