Abstract: Example embodiments of the present disclosure relate to obtaining of measured information and predicted information related to an Artificial Intelligence (AI)/Machine Learning (ML) model. In an example method, a first apparatus performs, during a first time period, first one or more measurements to obtain first measured information related to the first time period. The first apparatus determines, based on the first measured information, predicted information related to a second time period which is after the first time period. The first apparatus performs, during the second time period, second one or more measurements to obtain second measured information related to the second time period. The first apparatus transmits, to a second apparatus, the second measured information and the predicted information. In this way, a test mechanism framework may evaluate the prediction accuracy for AI/ML based prediction use case.

Abstract: First user equipments are detected out of a plurality of user equipments of a cellular communication system (S201). The user equipments respectively correspond to a distributed node of a federated machine-learning concept and respectively generate a partial machine-learning model, wherein partial machine-learning models generated by the plurality of user equipments are to be used to update a global machine-learning model at the network side of the cellular communication system. The first user equipments are user equipments comprising ready partial machine-learning models. Out of the first user equipments, second user equipments are selected at least based on a time information associated with the first user equipments (S203), the ready partial machine-learning models respectively generated by the second user equipments are acquired (S205), the global machine-learning model is updated using the ready partial machine-learning models acquired (S207), and convergence of the global machine-learning model updated by the ready partial machine-learning models acquired is determined (S209). In case convergence of the S207 global machine-learning model is not determined, a process comprising the detecting (S201), selecting (S203), acquiring (S205), updating (S207) and determining (S209) is repeated.

Abstract: A deep transfer reinforcement learning (DTRL) method based on transfer learning within a deep reinforcement learning (DRL) framework is provided to accelerate the GoB optimization decisions when experiencing environment changes in the same source radio network agent or when being applied from a source radio network agent to a target radio network agent. The transferability of the knowledge embedded in a pre-trained neural network model as a Q-approximator is exploited, and a mechanism to transfer parameters from a source agent to a target agent is provided, where the transferability criterion is based on the similarity measure between the source and target domain.

Abstract: Apparatuses and methods in a communication system are disclosed. Data on error between the location of more than one user terminal and the estimated location of the more than one user terminal is obtained, the estimated location obtained utilising radio frequency fingerprinting. It is evaluated whether the error is greater than a given threshold, and if so it is determined whether the error is due to radio frequency fingerprinting or not. Based on the determination decision is made on initialising update of radio frequency fingerprinting map.

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.
