Abstract

A base station according to an embodiment of the present disclosure includes a generation unit ( 35 ) that generates a beacon including switching information ( 41 ) indicating whether to cooperatively use a frequency channel and a transmission unit ( 32 ) that transmits the beacon.

First claim

The invention claimed is:

1. A base station belonging to a first basic service set (BSS), the base station comprising:
processing circuitry configured to generate a first beacon, the first beacon including switching information indicating a frequency channel is to be cooperatively used, channel identification information identifying the frequency channel, and an access parameter for accessing the frequency channel; and
a wireless module configured to transmit the first beacon to a first terminal belonging to the first BSS and another base station belonging to a second BSS different from the first BSS, wherein in response to receiving the first beacon, the first terminal and the another base station use the access parameter included in the first beacon to communicate using the frequency channel.

2. The base station according to claim 1 , wherein when the switching information indicates that the frequency channel is to be cooperatively used, the first beacon further includes channel identification information for identifying the frequency channel and an access parameter for accessing the frequency channel.

3. The base station according to claim 2 , wherein the access parameter includes TXOP Limit.

4. The base station according to claim 1 ,
wherein the wireless module is further configured to receive a cooperation request for requesting cooperative utilization of the frequency channel,
wherein the processing circuitry is configured to generate the first beacon including the switching information set to be information indicating that the frequency channel is to be cooperatively used in response to the cooperation request.

5. The base station according to claim 1 ,
wherein the processing circuitry is further configured to receive, from another base station, a second beacon including switching information set to be information indicating that the frequency channel is to be cooperatively used, channel identification information for identifying the frequency channel, and an access parameter for accessing the frequency channel,
wherein when the base station is using the frequency channel for communication, the processing circuitry generates the first beacon to include the access parameter for accessing the frequency channel in response to the second beacon.

6. The base station according to claim 5 , wherein the generation unit generates the first beacon including the switching information set to be information indicating that the frequency channel is to be cooperatively used in response to the second beacon.
