Embodiment Construction

[0028] Although the present invention is generally applicable to any multi-carrier system, the following description of the preferred embodiment of the present invention relates to OFDMA (Orthogonal Frequency Division Multiple Access) based systems (such as MRN (Mobile Radio The internet)). figure 1 The upper plot of is a time representation of a typical OFDMA signal with amplitude |h|. In the time domain, subcarriers are placed within a time distance of 1 / B from each other. figure 1 The lower figure of , relates to the same OFDMA signal as the upper figure, however this time illustrated in the frequency domain. The subcarriers are placed within a frequency distance of 1 / T from each other. The interval 1 / T is hereinafter referred to as the subcarrier interval. exist figure 1 In the OFDMA system shown, there are a total of N=BT subcarriers.

[0029] According to an embodiment of the present invention, frequency bands can be organized hierarchically to be divided into K cat...

Abstract

A communication network, wherein said network includes a plurality of communication elements that function as transmitters and / or receivers, in particular base stations and operating nodes being associated to at least one of said base stations, wherein the communication between said transmitters and said receivers is performed by way of generating and transmitting signals based on a multi-carrier modulation with a number of N subcarriers around a carrier frequency fc, said number of subcarriers can be negotiated for each receiver individually and is preferably a power of two.

Description

technical field [0001] The invention relates to a communication network and a method of operating a communication network, wherein said network comprises a plurality of communication units acting as transmitters and / or receivers, in particular base stations and operating nodes associated with at least one of said base stations, wherein , by having a carrier frequency f based on c The multi-carrier modulation of nearby N subcarriers is used to generate and transmit signals, performing communication between the transmitter and the receiver. Background technique [0002] Modern communication networks, such as next-generation mobile radio networks (MRNs), will have to support a greater number of energy-constrained nodes, such as autonomous (and possibly even energy self-sufficient) operating nodes. In the following, such operational nodes are referred to as M2M (Machine-to-Machine) nodes in order to distinguish them from "traditional" mobile communication nodes. Since the MRN ...
