    摘要： A base station (10) of an embodiment includes first and second wireless signal processing units (130, 140) and a link management unit (120). The first and second wireless signal processing units are configured to be able to transmit and receive a wireless signal using a first channel. The link management unit establishes a multi-link with a terminal apparatus by using the first and second wireless signal processing units, and sets a primary link used as a main and a secondary link used as an auxiliary during the multi-link. The link management unit transmits a first wireless frame requesting a change of the primary link to the terminal apparatus by using the first wireless signal processing unit set to the primary link, and the link management unit changes the primary link from the first wireless signal processing unit to the second wireless signal processing unit if either the first or second wireless signal processing unit receives the affirmative response from the terminal apparatus after the first wireless frame is transmitted.

    摘要： A base station (10) according to an embodiment includes first and second wireless signal processing units, and a link management unit. The first and second wireless signal processing units are configured to be able to transmit and receive wireless signals using first and second channels, respectively. The link management unit establishes a multi-link with a terminal apparatus by using the first and second wireless signal processing units (links #1 and #2), and sets an anchor link to be used in transmission and reception of control information regarding an operation of the multi-link. The link management unit transmits a first wireless frame requesting change of the anchor link by using the first wireless signal processing unit set to the anchor link, and changes the anchor link from the first wireless signal processing unit to the second wireless signal processing unit if either the first wireless signal processing unit or the second wireless signal processing unit receives a positive response from the terminal apparatus after the first wireless frame is transmitted.

    摘要： A base station (10) of an embodiment includes a first wireless signal processing unit (140), a second wireless signal processing unit (150), and a link management unit (120). The first wireless signal processing unit is configured to be able to transmit and receive wireless signals using the first channel. The second wireless signal processing unit is configured to be able to transmit and receive wireless signals using a second channel that is different from the first channel. The link management unit manages a link state of the first wireless signal processing unit and a link state of the second wireless signal processing unit. Upon receiving a request for a multi-link from a terminal apparatus, the link management unit uses at least one of the first wireless signal processing unit and the second wireless signal processing unit to execute association processing of the first wireless signal processing unit and association processing of the second wireless signal processing unit, and establishes a multi-link with the terminal apparatus.
