Abstract

A base station of an embodiment includes first and second wireless signal processing units, and a link management unit. The first wireless signal processing unit is configured to transmit and receive wireless signals using the first channel. The second wireless signal processing unit is configured to transmit and receive wireless signals using a second channel different from the first channel. The link management unit manages link states of the first and second wireless signal processing units. Upon receiving a request for a multi-link from a terminal apparatus, the link management unit uses at least one of the first and second wireless signal processing units 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.

Claims (14)

1 . A base station comprising:

a first wireless signal processing circuit configured to transmit and receive a wireless signal using a first channel;

a second wireless signal processing circuit configured to transmit and receive the wireless signal using a second channel different from the first channel; and

processing circuitry configured to:

broadcast a beacon signal including link information indicating a plurality of channels that can be used for a multi-link;

receive a single association request from a terminal apparatus via one of the first wireless signal processing circuit or the second wireless signal processing circuit indicated in the beacon signal, the single association request requesting an establishment of the multi-link between the base station and the terminal apparatus; and

establish the multi-link with the terminal apparatus by responding to the single association request with a single response.

2 . A terminal apparatus comprising:

a first wireless signal processing circuit configured to transmit and receive a wireless signal using a first channel;

a second wireless signal processing circuit configured to transmit and receive the wireless signal using a second channel different from the first channel; and

processing circuitry configured to:

receive a beacon signal including link information indicating a plurality of channels that can be used for a multi-link;

transmit a single association request to a base station via one of the first wireless signal processing circuit or the second wireless signal processing circuit indicated in the beacon signal, the single association request requesting an establishment of the multi-link between the base station and the terminal apparatus; and

establish the multi-link with the base station by receiving a single response to the single association request.
