Systems and methods are disclosed herein for User Equipment (UE) assisted data collection for mobility prediction. In one embodiment, a method performed by a UE for UE-assisted data collection for mobility prediction comprises receiving, from a network node of a cellular communications system, a UE trajectory prediction model for predicting a UE trajectory. The method further comprises executing the UE trajectory prediction model to generate a predicted trajectory for the UE, comparing the actual UE trajectory to the predicted UE trajectory, and sending, to a network node of the cellular communications system, a result of the comparison of the actual UE trajectory to the predicted UE trajectory. In this manner, mobility prediction performance is improved.

Techniques are described for cell reselection technology. An example wireless communication method comprises transmitting, by a network node, one or more black cell lists to a communication node, where each black cell list describes a range of physical cell identifiers (PCI) of one or more network nodes that are prevented from being used by the communication node for reselection, and where each black cell list is associated with one or more network identifiers (IDs) of the one or more network nodes or an indication of a type of network that indicates a type of service provided by one network node.
