==OFDM COMMUNICATIONS SYSTEM WITH METHOD FOR DETERMINATION OF SUBCARRIER OFFSET FOR OFDM SYMBOL GENERATION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18585977 titled 'OFDM COMMUNICATIONS SYSTEM WITH METHOD FOR DETERMINATION OF SUBCARRIER OFFSET FOR OFDM SYMBOL GENERATION

The abstract of this patent application discusses the need to shift the middle subcarrier of the baseband OFDM signal of each numerology to comply with a nested grid, which can be signalled to the UE with reduced overhead. The innovation aims to reduce overhead in OFDM communication, potentially increasing system bandwidth and reducing power consumption in the UE.

* Transmitter generates an OFDM signal with a specific subcarrier spacing and offset for each numerology.
* Middle subcarrier frequency of usable resource blocks is offset from the carrier frequency by a defined formula.
* Transmission of the OFDM signal according to the subcarrier spacing and offset.

Reducing overhead can lead to decreased power consumption in UE devices, extending battery life and improving overall efficiency in wireless communication systems.


==Original Abstract Submitted==

The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (μ), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.
