  • Publication number: 20250252268
    Abstract: Methods and systems are provided for generating and using a unified fine-tuning dataset to fine-tune a language model. In embodiments described herein, a first labeled dataset having a first format of human feedback associated with performance of a pre-trained language model is accessed. Additionally, a second labeled dataset having a second format of human feedback associated with performance of the pre-trained language model is accessed. Thereafter, a unified fine-tuning dataset is generated by converting the second labeled dataset to a refined labeled dataset having the first format of human feedback and aggregating the first labeled dataset having the first format of human feedback with the refined labeled dataset having the first format of human feedback. The pre-trained language model is fine-tuned using the unified fine-tuning dataset and output for subsequent utilization.

  • Publication number: 20250254636
    Abstract: Techniques discussed herein can facilitate neighbor cell measurements with non-cell-defined synchronization signal blocks (NCD-SSB). One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive an indication of a NCD-SSB and a cell-defined (CD)-SSB (CD-SSB) configuration. The one or more processors further perform a measurement procedure to obtain a cell measurement value associated with a SSB wherein the SSB is one of the NCD-SSB or the CD-SSB. Subsequently, the one or more processors compare the cell measurement value with a threshold value; and perform measurement of a neighbor cell when the cell measurement value does not satisfy the threshold value.

  • Publication number: 20250247728
    Abstract: Systems, methods, and devices are provided for processing potentially overlapping measurement gaps. In one example, a baseband processor of a user equipment (UE), includes one or more processors configured to receive a first measurement gap configuration configuring a first measurement gap and a second measurement gap configuration configuring a second measurement gap. A measurement gap (MG) proximity between the first measurement gap and the second measurement gap is determined and evaluated with respect to a proximity condition. The proximity condition defines a minimum time between measurement gaps. In response to the MG proximity violating the proximity condition, the one or more processors are configured to determine that the first measurement gap and the second measurement gap are overlapping, and in response, select one of the first measurement gap or the second measurement gap for receiving reference signals.

  • Patent number: 12369152
    Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching.

  • Patent number: 12369060
    Abstract: Methods, apparatuses, and systems are disclosed for configuring measurement timings in connection with UEs that are capable of signaling whether a measurement gap (MG) is needed to measure a target frequency carrier. For example, a measurement period may be determined for the target frequency carrier based on the UE indicating that it supports per-frequency range (FR) MGs, and determining that the FR of the target frequency carrier does not include any current serving cell(s). If the UE indicates that no MG is needed to measure the target frequency carrier, then the measurement period may be based on an SMTC, and may be further based on a predefined effective measurement gap repetition period (MGRP). If the UE indicates that a MG is needed, then the measurement period may be based on the SMTC, and may be further based on the effective MGRP or a per-UE MGRP.

One example aspect is a user equipment (UE), configured to receive a network assistance indication associated with an interfering signal, where the interfering signal interferes with a physical downlink shared channel (PDSCH) transmission. A time resource allocation of the interfering signal is different than a time resource allocation of the PDSCH transmission. The UE is further configured to determine an interference and noise covariance estimation mechanism based on the network assistance indication then perform interference and noise covariance estimation based on the noise covariance estimation mechanism. The UE is further configured to perform mitigation of the interfering signal using a mitigation mechanism based on the interference and noise covariance estimation.
