    摘要: Current steering digital-to-analog converters (DACs) are described. These DACs are suitable for high speed operation. Weight transistors conventionally used in DACs are replaced with resistors, resulting in a lower RC constant. Further, the resistors cause a smaller voltage drop, thus improving the voltage headroom of the DAC. Additionally, the current steering switches are biased in the triode region, as opposed to the saturation region as in conventional designs. Biasing the switches in the triode region results in a smaller drain-source voltage, which further improves the voltage headroom of the DAC. The triode operation further results in a substantially smaller output impedance, which leads to the output voltage being dictated primarily by the output transistor of the current path. Lastly, reset switches are added which reduce data-dependent memory effects that can otherwise produce distortion.

    摘要: A semiconductor structure is provided. The semiconductor structure includes a semiconductor wafer and a test structure. The semiconductor wafer has a substrate having a scribe line area, a first die area and a second die area. The first die area and the second die area are separated by the scribe line area extending along a first direction. The test structure is disposed in the scribe line area. The test structure includes a test device and a first test pad. The test device has a physical characteristic similar to a semiconductor device fabricated in the first die area or the second die area. The first test pad is electrically connected to the test device. A first distance between the first test pad and the first die area gradually increases from a center region to a peripheral region of the first test pad in the first direction.

    摘要: A method to establish and activate an MA PDU session for data transmission over a selected access is proposed. UE initiates a UE-requested PDU session establishment procedure. Once the UE receives a PDU SESSION ESTABLISHMENT ACCEPT message with ATSSS container IE, the UE can consider the MA PDU session has been activated and user plane resources are successfully established on the selected access. A method to convert an SA PDU session to an MA PDU session for data transmission over a selected access is proposed. UE initiates a UE-requested PDU session modification procedure. Once the UE receives a PDU SESSION MODIFICATION COMMAND message with ATSSS container IE, the UE can consider the MA PDU session has been converted from the SA PDU session and user plane resources are successfully established on the selected access.

    摘要: This invention presents methods leveraging artificial intelligence and machine learning (AI/ML) models to enhance wireless communications efficiency in 5G/6G networks. The processes involve storing, configuring, and transferring AI/ML models within base stations and user equipment devices (UE), allowing for localized decision-making and improved network performance. Features include dynamic model activation/deactivation, model compression/decompression, and encoding/decoding method negotiation. Periodic or condition-driven model updates ensure responsiveness to network changes, while model replacements enable upgrades and iterations. The system facilitates seamless handovers between base stations, with information sharing about model capabilities and UE specifics. Model storage and configuration can also occur in the UE, empowering it for local decision-making in variable or challenging network conditions. The techniques contribute to significant performance, efficiency, and reliability improvements in 5G/6G wireless networks.

    摘要: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be wireless equipment. The wireless equipment selects a first subset of beams to be utilized for beam management. The beams are from a set of first type of beams used for communication with a base station or a UE. The wireless equipment measures signals transmitted on a second subset of beams. The beams are from the set of first type of beams or from a set of second type of beams. The wireless equipment measures the signals over a time window. The wireless equipment inputs the measurements to a computational model. The wireless equipment receives predictions of channel measurements on the first subset of beams from the computational model.
