Abstract
Provided are an apparatus and a method for multilink adaptation. A transmitter searches a main link and a sub-link through a beam-training procedure, and transmits link change information to a receiver during data transmission performed through either the main link or the sub-link in a transmission opportunity. The transmitter receives an acknowledgement (ACK) message for the link change information, and changes the main link or the sub-link in accordance with the link change information.
