Abstract: In wireless communication, a device may change, add, or handover between cells of network access for inter-cell mobility. This may include Layer 1 and/or Layer 2 (L1/L2) signaling for a user equipment (UE) moving between cells in a network. The signaling can reduce the mobility interruption time and improve robustness of a handover. The movement may be triggered by the network or the UE. A Layer 1 and/or Layer 3 (L1/L3) measurement is used for the inter-cell mobility. The mobility may be coordinated based on interactions between a centralized unit (CU) and a distributed unit (DU). The procedures can reduce interruption time and improve reliability.

Abstract: In wireless communication, a device may handover between cells of network access for inter-cell mobility without interruptions. In a Dual Active Protocol Stack (DAPS) handover, the user equipment (UE) maintains simultaneous connection with the source node and target node until releasing the source cell after successful access to the target cell. The source node may generate the power coordination and/or resource coordination parameters or configurations that are transmitted to the target node during the handover. When there is a centralized unit (CU) split from a distributed unit (DU), the CU or DU may generate and/or transmit the parameters/configurations to the peer node.

Abstract: A computer-implemented method can be used for searching for an optimal hyperparameter combination for defining a machine learning model. The method includes performing tests of hyperparameter combinations. Each test of hyperparameter combination includes a training phase and a test phase. The training phase is adapted to train the machine learning model from training data and the test phase is adapted to calculate a performance score associated with the hyperparameter combination tested from test data. The optimal hyperparameter combination corresponds to the hyperparameter combination having obtained the best performance score among the hyperparameter combinations tested. A weighting coefficient is used for adjusting an amount of training data used for the training phase. The weighting coefficient is dynamically adapted during different tests of the hyperparameter combinations.
