Publication number: 20240163805Abstract: 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.Type: ApplicationFiled: January 25, 2024Publication date: May 16, 2024Inventors: Joseph Patrick BURKE, Muhammad Sayed Khairy ABDELGHAFFAR, Charline HAO, Joseph Binamira SORIAGA, Lai Kan LEUNG, Gurkanwal Singh SAHOTA, Tingfang JI, Krishna Kiran MUKKAVILLI, Allen Minh-Triet TRAN
