  • Publication number: 20250142659
    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media of communication. A terminal device receives, from a network device, a first configuration information transmitted on a first cell, wherein the first configuration information includes a set of TCI states, and the set of TCI states is associated with a second cell different from the first cell. The terminal device receives a first activation command to activate one or more TCI states, wherein the one or more TCI states comprise at least one TCI state from the set of TCI states. The terminal device applies the one or more activated TCI states from a first slot after a predefined timing. In this way, a beam for the second cell can be indicated according to the TCI state indicated by the first cell before serving cell change; accordingly, the latency, the overhead and the interruption time during the inter-cell mobility can be reduced.
