Abstract
Disclosed is a method comprising transforming, by a terminal device, a signal constellation based on one or more parameter values, wherein the one or more parameter values indicate a shape of the transformed signal constellation; and transmitting, by the terminal device, one or more signals based at least partly on the transformed signal constellation.
Claims20
An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- transform a signal constellation based on one or more parameter values, wherein the one or more parameter values indicate a shape of the transformed signal constellation;
- and
- transmit one or more signals based at least partly on the transformed signal constellation, wherein the signal constellation is transformed by adjusting a scaling of an imaginary axis of the signal constellation based on a first parameter value of the one or more parameter values, and controlling a level of asymmetry of the signal constellation based on a second parameter value of the one or more parameter values.
An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- indicate, to a terminal device, one or more parameter values, wherein the one or more parameter values indicate a shape of a transformed signal constellation;
- and
- receive, from the terminal device, one or more signals based at least partly on the transformed signal constellation, wherein a first parameter value of the one or more parameter values indicates a scaling of an imaginary axis of the transformed signal constellation, and a second parameter value of the one or more parameter values indicates a level of asymmetry of the transformed signal constellation.
