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.

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.
