Abstract: Systems, methods, apparatuses, and computer program products for verifying positioning accuracy. One method may include transmitting, by testing equipment, a request to measure location coordinates to a device, receiving, by the testing equipment, from the device, a model inference comprising at least one location coordinate, and determining, by the testing equipment, whether a difference between the model inference and at least one ground truth is within a threshold value for a defined number of samples, wherein the at least one ground truth comprises at least one known location coordinate of a test point.

Abstract: Test equipment (TE) may, while in a test configuration, cause transmission of a first reference signal for receipt by a communication device under test (DUT). The TE may receive a first line-of-sight indicator value as determined by the DUT in accordance with a method having a known accuracy. While in the test configuration, the TE may cause transmission of a second reference signal for receipt by the DUT. The TE may receive a second line-of-sight indicator value as determined by the DUT based at least in part on a trained machine learning (ML) model. The TE may determine an error value between the first line-of-sight indicator value and the second line-of-sight indicator value. Based at least in part on the error value, the TE may determine whether the trained ML model passes a conformance test related to estimation of line-of-sight indicator values by the trained ML model.

Abstract: Example embodiments of the present disclosure are related to artificial intelligence/machine learning (AI/ML) model test. A first apparatus transmits test configuration information to a second apparatus, the test configuration information indicating a test mode of an AI/ML model with respect to at least one transmission and reception unit (TRP), the at least one TRP being arranged within an environment based on a test plan for at least one test channel indicator. The first apparatus receives, from the second apparatus, at least one predicted channel indicator for the at least one TRP, the at least one predicted channel indicator being derived by the second apparatus using the AI/ML model. The first apparatus determines a test result for the AI/ML model based on a comparison between the at least one predicted channel indicator and the at least one test channel indicator, the test result indicating whether the AI/ML model is validated.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for dynamic configuration of measurement parameters for sidelink positioning. In the method, a first apparatus receives, from a second apparatus, a plurality of measurement configurations for sidelink positioning. Moreover, in accordance with a determination that a first trigger condition defined the plurality of measurement configurations is met, the first apparatus determines a first measurement configuration corresponding to the first trigger condition from the plurality of measurement configurations. Thereby, the proposed solutions can advantageously improve the positioning accuracy.

Abstract: Embodiments of the present disclosure relate to small data transmission (SDT). In the embodiments, a distributed unit (DU) of a network device determines that data for small data transmission (SDT), from a terminal device comprises data for at least one signaling radio bearer (SRB), without comprising data for a data radio bearer, DRB. The DU transmits, to a control plane (CP) of a central unit (CU) of the network device, an indication that the data for SDT is associated with the at least one SRB, and without being associated with a DRB. In this way, the SDT can be optimized.
