==SUB-BAND-FULL-DUPLEX INTERFERENCE MITIGATION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240163805 titled 'SUB-BAND-FULL-DUPLEX INTERFERENCE MITIGATION

==Simplified Explanation==

The patent application describes a method for mitigating UE-to-UE interference during an SBFD slot in a TDD system by filtering the DL signal to block a specific sub-band.

* During an uplink TDD slot, a UL UE transmits a signal in a slot frequency range.
* Similarly, during a downlink TDD slot, a DL UE receives a signal in the slot frequency range.
* In an SBFD slot, a UL UE transmits a signal in only the first sub-band of the slot frequency range.
* Similarly, a DL UE receives a signal in only the second sub-band of the slot frequency range, distinct from the first sub-band.
* The DL UE can mitigate UE-to-UE interference during an SBFD slot by filtering the DL signal to block the second sub-band.

== Potential Applications ==
This technology can be applied in TDD systems to improve spectral efficiency and reduce interference between UEs.

== Problems Solved ==
1. Mitigating UE-to-UE interference during SBFD slots in TDD systems.
2. Enhancing the overall performance of TDD systems by optimizing frequency resource allocation.

== Benefits ==
1. Improved signal quality for UEs during SBFD slots.
2. Enhanced system capacity and throughput.
3. Increased reliability and stability of TDD communications.

== Potential Commercial Applications ==
"Mitigating UE-to-UE Interference in TDD Systems for Enhanced Performance"

== Possible Prior Art ==
There may be prior art related to TDD systems and interference mitigation techniques in wireless communications.

== Unanswered Questions ==
=== How does this technology impact the overall latency in TDD systems? ===
The patent application does not address the potential impact on latency when implementing the filtering technique to mitigate interference.

=== What are the specific hardware requirements for implementing this filtering method in DL UEs? ===
The patent application does not provide details on the hardware specifications or additional components needed for DL UEs to filter out the second sub-band during SBFD slots.


==Original Abstract Submitted==

during an uplink tdd slot, an ul ue transmits an ul signal that occupies a slot frequency range. similarly, during a dl tdd slot, a dl ue receives a dl signal that occupies the slot frequency range. but during an sbfd slot, a ul ue transmits a ul signal that occupies only a first sub-band of the slot frequency range. similarly, a dl ue receives a dl signal during an sbfd slot that occupies only a second sub-band of the slot frequency range. the second sub-band is distinct from the first sub-band. the dl ue may thus mitigate ue-to-ue interference during an sbfd slot by filtering the dl signal to substantially block the second sub-band from being received at the dl ue.
