  • SLOT INDICATION FOR UPLINK CONTROL CHANNEL CARRIER SWITCH
    Publication number: 20250070946
    Abstract: Some techniques and apparatuses described herein enable transmission of an uplink control channel in a cross-carrier fashion, where determination of a slot for the transmission is performed based at least in part on a reference component carrier (CC), of a plurality of CCs. For example, the reference CC may be indicated by scheduling information associated with a downlink channel, or may be determined by the UE (e.g., based at least in part on an order associated with the plurality of CCs and availability of a slot for an uplink control channel on the plurality of CCs). In this way, ambiguity with regard to determination of the slot for transmission of the uplink control channel is reduced, thereby providing improved control channel performance, improved resource utilization, and more robust implementation of cross-carrier uplink feedback.

  • COMMON TCI SWITCH DELAY FOR CARRIER AGGREGATION
    Publication number: 20250070849
    Abstract: An apparatus and system of establishing a Transmission Configuration Indication (TCI) state switch delay are described. The TCI state switch delay for a reference signal (RS) on a component carrier (CC) in intra-band carrier aggregation (CA) is dependent on whether a TCI state indicated in the DCI is known based on a type of Quasi Co-Location (QCL) and whether a common TCI state ID is known on the CC. The delay is known for a delay of QCL-typeD RS on the CC or any other QCL-typeD RS in the CC set that contains the CC. The delay may be based on that of a single CC delay, with the slot where the new TCI state applies determined based on a carrier with a smallest subcarrier spacing (SCS) in the CC or the CC set.

  • PIXEL SENSORS AND METHODS OF FORMING THE SAME
    Publication number: 20250072143
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.
