Patent №: 11895690 (February 6, 2024) – Techniques for reference signal interference canceling or rate matching. A user equipment (UE) receives information linking cells from different radio access technologies. The UE measures the first cell, checks if it meets a threshold, and then takes action on the reference signal of the second cell based on this measurement and the cell association.

Patent №: 11895634 (February 6, 2024) –  Control resource set (CORESET) configuration for narrowband new radio (NR). A user equipment (UE) monitors a physical downlink control channel (PDCCH) in one part of the CORESET within the channel bandwidth. The CORESET also has another part outside the channel bandwidth. The UE uses this monitoring to receive a system information block (SIB).

Patent №: 11895608 (February 6, 2024) –  Timing offset selection in non-terrestrial network

Patent №: 11895048 (February 6, 2024) –  Sounding reference signal antenna switching in scheduled entities having at least four antennas, brings forward innovations in the field of communication systems. This patent describes a method by which a scheduled entity with at least four antennas may simultaneously support antenna switching and uplink (UL) multiple-input multiple-output (MIMO) communication. By configuring the antennas based on the SRS configuration, efficient and seamless communication is achieved.

Patent №: 11894914 (February 6, 2024) –  Cell type selection for non-terrestrial networks. This invention focuses on user equipment (UE) selecting or reselecting a target cell in a non-terrestrial network, particularly after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. By determining the cell type of the target cell, be it LEO, GEO, moving, fixed, temporarily fixed LEO, or permanently fixed LEO, the UE can make optimized selection or reselection decisions for maintaining connectivity.
