Original Abstract Submitted

embodiments of the present disclosure relate to methods and apparatus for beam maintenance in a radio access network, in particular, through random access preamble transmission for beam maintenance. a terminal device receives, from a network device, a resource configuration for contention-free random access. the resource configuration indicates a plurality of cfra resources each associated with a respective synchronization signal and physical broadcast channel block index or channel state information reference signal index. the plurality of cfra resources are applicable for timing advance acquiring in a target network device. the terminal device transmits, to the target network device, one or more cfra physical random access channels based on the resource configuration. in this way, beam maintenance may be performed based on an ssb index or csi-rs index associated with one of the transmitted cfra prach(s) before a cell switch command or a random access response.
