Method of reestablishing radio link and wireless communication device using the method
Abstract:
A method of reestablishing a radio link which is performed by a wireless communication device that communicates with a peer node includes monitoring quality of a radio link used for communication with the peer node, determining whether radio link reestablishment is needed when the quality of the radio link is less than or equal to a reference value, determining a beam search parameter using at least one of information on the activation status of the radio link and mobility information of the peer node, performing a beam search necessary for radio link reestablishment according to the beam search parameter, and reestablishing a radio link with the peer node using a found beam.
