==FREQUENCY DOMAIN IMBALANCE CORRECTION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18049282 titled 'FREQUENCY DOMAIN IMBALANCE CORRECTION

==Simplified Explanation==

The patent application describes methods, systems, and devices for wireless communications, specifically focusing on balancing the in-phase and quadrature-phase portions of a transmission chain based on an estimation of frequency domain imbalance.

* User equipment (UE) receives a reference signal from a network entity.
* The UE transmits an estimation of frequency domain imbalance between the in-phase and quadrature-phase portions of the reference signal to the network entity.
* The estimation is based on a precoding matrix associated with transmissions from the network entity and channel conditions between the UE and the network entity.
* The network entity performs an imbalance compensation operation to balance the in-phase and quadrature-phase portions of the transmission chain.
* The UE receives a data transmission from the network entity based on the indication of the estimation of the frequency domain imbalance.

== Potential Applications ==
This technology can be applied in various wireless communication systems to improve the quality and reliability of data transmissions.

== Problems Solved ==
1. Frequency domain imbalance in wireless communications.

==Original Abstract Submitted==

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a reference signal from a network entity. The UE may transmit, to the network entity, an estimation of a frequency domain imbalance between an in-phase portion of the reference signal and a quadrature-phase portion of the reference signal based on a precoding matrix associated with transmissions from the network entity and an estimation of one or more channel conditions between the UE and the network entity. The network entity may perform an imbalance compensation operation that balances the in-phase portion and the quadrature-phase portion of the transmission chain based on the estimation of the frequency domain imbalance. The UE may receive, from the network entity, a data transmission based on transmitting the indication of the estimation of the frequency domain imbalance.
