1. A base station comprising:
a first wireless signal processing unit configured to be able to transmit and receive a wireless signal using a first channel;
a second wireless signal processing unit configured to be able to transmit and receive a wireless signal using a second channel that is different from the first channel; and
a link management unit configured to establish a multi-link with a terminal apparatus using the first wireless signal processing unit and the second wireless signal processing unit, set the first wireless signal processing unit as a primary link used as a main link in the multi-link, and set the second wireless signal processing unit as a secondary link used as an auxiliary link in the multi-link, wherein
when the secondary link is in an active mode and a first condition is satisfied in the multi-link, the link management unit sets the secondary link to an operation pause mode in which power consumption is lower than that of the active mode, and
when the secondary link is in the operation pause mode and a second condition is satisfied in the multi-link, the link management unit sets the secondary link to the active mode.
