Embodiment Construction

[0020] In the context of the present disclosure, a wireless communication network may be a communication network arranged for radio communication between devices or nodes. Devices adapted for wireless and / or radio communication may be considered wireless devices. A wireless device may in particular be a terminal or user equipment, or a network node like a base station. A base station may in particular be an eNodeB (eNB). Wireless or radio communication may be performed in particular according to telecommunication standards such as LTE and / or may be cellular communication, which may be based on cells that are controlled by the network, in particular by one or more network nodes (radio) of the network. Nodes), such as one or more base stations or eNBs, to define and / or provide and / or control and / or provide services.

[0021] For wireless communication, especially transmission, (digital) information (eg in the form of bits or signal bits) may be mapped onto a frequency spectrum...

Abstract

There is disclosed a method for operating a wireless device in a wireless communication network, the method comprising modulating a plurality of input bits (N), wherein modulating comprises choosing afirst number (k) of frequencies from a predetermined set of a total number (NF) of frequencies, the first number (k) being larger than 1, and performing quadrature amplitude modulation to a second number (NQ) on each of the first number (k) of frequencies. There are further disclosed related methods and devices.

Description

technical field [0001] The present disclosure relates to wireless communications, and more particularly to modulation techniques for wireless communications. Background technique [0002] The use and expansion of wireless communications, particularly such cellular technologies in use, is growing and is expected to continue to grow in the near and not so near future. However, the spectral resources to support increased usage are limited. One way to improve support is to improve the spectral efficiency of wireless data transfer, so that a given (frequency) spectrum (eg, the spectrum licensed for communication) can be used to transmit more data in a given time. Contents of the invention [0003] It is an object of the present disclosure to describe approaches for modulating signals which provide efficient data transmission, in particular in terms of data volume over time and / or good spectral efficiency. [0004] A method for operating a wireless device in a wireless communi...
