Abstract: Systems, methods, apparatuses, and computer program products for network controlled repeater forward link beam switch testing. A method may include transmitting an access link beam configuration to a network controlled repeater (NCR). The method may also include initiating, by the NCR, a beam switch operation based on implementation of the received access link beam configuration. The method may further include transmitting, by NCR, an access link beam based on the beam switch operation. In addition, the method may include measuring the received access link beam of the NCR. Further, the method may include determining test metrics based on the measuring. The method may also include verifying the beam switch operation based on the test metrics.

Abstract: Embodiments of the present disclosure relate to a test framework to evaluate the CSI prediction accuracy for AI/ML based CSI prediction use case without the need for the DUT to send the ground truth to the test equipment separately. Further, embodiments of the present disclosure propose a procedure to obtain the parameter values predicted by the DUT and the corresponding ground truth at the TE side independently during the conformance testing.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, devices and computer readable storage medium for two-sided model-based communication functionality. In a method, a first apparatus obtains a reference data set of a communication functionality. The reference data set includes reference data associated with a plurality of terminal devices, a plurality of network devices and at least one test equipment. The first apparatus updates a reference encoder of the communication functionality based on at least the reference data. The first apparatus updates a reference decoder of the communication functionality based on at least the reference data. At least one of the updated reference encoder or the updated reference decoder is used for optimization of the communication functionality by a further apparatus.

Abstract: An apparatus configured to: enter a test mode; receive, from a test equipment, an indication of at least one first model used at a first side of a two-sided model; request, from a model repository, at least one second model for use at a second side of the two-sided model, wherein the at least one second model is selected based, at least partially, on the at least one first model; and receive, from the model repository, the at least one second model. An apparatus configured to: receive, from a test equipment, a model validation request; provide a data set to at least one model to obtain an inference validation response, wherein the at least one model is used at a first side of a two-sided model; transmit, to the test equipment, the inference validation response; and receive, from the test equipment, a validation sequence result.

Abstract: A method, apparatus, and computer program product configure an uplink timing advance loop in order to facilitate uplink transmission including uplink transmission following a change in the uplink beam. In the context of a method, it is determined that a plurality of timing advance loops are supported to a plurality of transmission points. In response to a triggering mobility event, the method determines whether uplink timing information is available for a respective transmission point. In response to a determination that uplink timing information is unavailable for the respective transmission point, the method configures an uplink timing advance loop by synchronizing to a downlink beam and/or reference signal from the respective transmission point setting a timing advance value and then using a gradual timing adjustment procedure to adjust the uplink timing advance loop.
