  • Publication number: 20250261105
    Abstract: A method for a user equipment (UE) monitors a physical downlink control channel (PDCCH) for power saving signaling. The method includes receiving a discontinuous reception (DRX) configuration from a base station (BS) to configure the UE to monitor a scheduling signal on the PDCCH within a DRX active time for multiple transmit-receive points (TRP). Power saving signaling configurations are received from the BS to configure the UE to monitor power saving signaling on the PDCCH for the multiple TRPs, each power saving signaling configuration for a different TRP and comprising a time offset between a start of a nearest power saving signaling and a start of a DRX on-duration time. The PDCCH is monitored according to the power saving signaling configuration. The UE wakes up to monitor the PDCCH for the scheduling signal in the DRX active time according to the DRX configuration when receiving the power saving signaling.

  • Publication number: 20250234595
    Abstract: Inner spacers between a source/drain region of a nanostructure transistor and sacrificial nanostructure layers of the nanostructure transistor are removed prior to formation of a gate structure of the nanostructure transistor. The sacrificial nanostructure layers are removed, and then the inner spacers are removed. The sacrificial nanostructure layers are then replaced with the gate structure of the nanostructure transistor such that the gate structure and the source/drain region are spaced apart by air gaps that result from the removal of the inner spacers. The dielectric constant (or relative permittivity) of the air gaps between the source/drain region and the gate structure is less than the dielectric constant of the material of the inner spacers. The lesser dielectric constant of the air gaps reduces the amount of capacitance between the source/drain region and the gate structure.

  • Patent number: 12317146
    Abstract: A method of configuring a set of active cells among neighboring cells to reduce latency and interruption for inter-cell mobility is proposed. The set of active cells is an active set of cells among which UE can do fast cell switching. The set of active cells is configured by the network based on UE measurement report or network deployment information. UE maintains the configuration and can perform pre-synchronization to the configured active cells in downlink (DL) only or in both DL and uplink (UL). UE maintains the DL/UL synchronization with the active cells, and applies configuration once UE is indicated to switch to an active cell as the target cell. Because UE maintains the configuration and DL/UL timing of the target cell before receiving the cell-switch command, the mobility latency and interruption time for inter-cell mobility is reduced.
