Base station that controls multiple wireless signal processing circuitry
A base station of an embodiment includes first and second wireless signal processing units and a link management unit. 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 processor receives the affirmative response from the terminal apparatus after the first wireless frame is transmitted.
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 a wireless signal using a second channel different from the first channel; and
processing circuitry configured to establish a multi-link with a terminal apparatus by using the first wireless signal processing circuit and the second wireless signal processing circuit, wherein
the processing circuitry is further configured to:
transmit a first wireless frame requesting a change in a channel of the second wireless signal processing circuit to the terminal apparatus by using the first wireless signal processing circuit, and
transmit a second wireless frame including information indicating a timing of the change by using at least one of the first wireless signal processing circuit and the second wireless signal processing circuit if either the first wireless signal processing circuit or the second wireless signal processing circuit receives a first affirmative response to the first wireless frame;
change the channel of the second wireless signal processing circuit from the second channel to a third channel different from each of the first channel and the second channel at the timing; and
the processing circuitry is further configured to:
transmit a third wireless frame requesting a change of the channel of the second wireless signal processing circuit to the terminal apparatus by using the first wireless signal processing circuit when the second wireless signal processing circuit is set to an operation pause mode;
change the channel of the second wireless signal processing circuit from the second channel to the third channel while maintaining the channel in the operation pause mode if either the first wireless signal processing circuit or the second wireless signal processing circuit receives a second affirmative response to the third wireless frame, and
communicate with the second wireless signal processing circuit using the third channel after the change in the channel of the second wireless signal processing circuit is applied and the second wireless signal processing circuit wakes up from the operation pause mode to an active mode.
