Abstract: This application provides a communications method, apparatus, and system, and a storage medium. In consideration that a synchronization signal and PBCH block (SSB) is introduced into a new radio (NR) system, the first physical cell identifier (PCI) corresponds to a first SSB, and the second PCI corresponds to a second SSB, the first access network device determines, based on the first PCI of the first cell and the second PCI of the second cell, that the first PCI conflicts with the second PCI. In this way, a PCI conflict corresponding to the SSB in the NR system can be detected. This helps eliminate or reduce PCI conflicts in an NR network, improve a success rate of terminal handover, and further reduce a call drop rate.

Abstract: The present disclosure relates to information transmission methods. In one example method, a first network device or a second network device triggers a terminal device to be handed over from a first cell to a second cell. The terminal device sends second information, where the second information includes information about a radio link failure that occurs between the terminal device and the second cell, or information about beam failure recovery that occurs between the terminal device and the second cell. The first network device or the second network device performs mobility robustness optimization based on the second information.

Abstract: A minimization of drive tests (MDT) method and apparatus includes: a network device sends MDT configuration information to a terminal, where the MDT configuration information includes an MDT measurement parameter of a shared spectrum; and the terminal performs MDT on the shared spectrum based on the MDT configuration information to obtain a measurement report, and sends the measurement report to the network device. The MDT may be performed on a shared spectrum to obtain a measurement report. The measurement report may better reflect an application status of the shared spectrum, to help optimize a network device that performs communication by using the shared spectrum.
