Problems solved by technology

[0003] However, such methods have disadvantages in terms of performance and latency, specifically in the presence of channel distortion
For example, scaling by CP to keep CP overhead constant results in performance loss due to channel multipath scatter

Abstract

The disclosure relates to a transmitter device (1300) for use in a wireless communication system, the transmitter device (1300) comprising: a processor (1310) configured to select a numerology set (1313) from a quantity of at least two numerology sets (1311, 1312), wherein the numerology set (1313) identifies a set of transmission parameters for transmitting a transmit signal (1322) over a transmission channel, wherein the selection is based on a Signal-to-Noise Ratio (SNR) of the transmission channel; and a transmitter (1320), configured to transmit the transmit signal (1322) based on the selected numerology set (1313).

Description

technical field [0001] The present invention relates to techniques for transmitting a transmit signal, in particular a multi-carrier signal and a single-carrier signal, in a communication system based on the selection of a parameter set identifying transmit parameters for transmitting the transmit signal over a transmit channel gather. In particular, the present disclosure relates to methods and devices for selecting parameter sets with respect to multicarrier parameters, e.g., according to channel parameters such as signal-to-noise ratio (SNR), in particular, under delay constraints choose. Background technique [0002] A numerology defines a set of transmit parameters, usually determined by hardware system requirements. Tuning of such parameters is performed within the limits imposed by the hardware. For example, in a Long Term Evolution (LTE) transceiver with 15KHz subcarrier spacing, Fast Fourier Transforms can be easily implemented if the operating subcarrier spacing...
