Abstract
According to one embodiment of the present invention, a method for efficient channel use is disclosed. The channel use method may comprise the steps of: selecting a specific channel from channels configured to be shared along with a homogeneous or heterogeneous communication scheme; and performing an interference avoidance procedure if the selected channel interferes with a neighboring access point. The avoidance procedure may comprise one or more of a process of making a request to switch a channel of the neighboring access point, a process of notifying to the neighboring access point, and a process of changing the selected channel into another channel.
Claims2
A method of efficiently using channels by an access point, the method comprising the steps of:
- selecting a specific channel from channels configured to be shared along with a heterogeneous communication scheme;
- and
- performing an interference avoidance procedure if the selected channel interferes with a neighboring access point,
- wherein the avoidance procedure comprises a process of making a request to switch a channel of the neighboring access point, a process of notifying to the neighboring access point, and a process of changing the selected channel into another channel,
- wherein the neighboring access point uses a heterogeneous communication scheme,
- wherein the process of making the request to switch the channel comprises requesting an entity that is responsible for a control function to switch the channel of the neighboring access point,
- wherein the process of notifying comprises transmitting a signal indicating that the selected channel interferes with the neighboring access point,
- wherein the signal is transmitted through a dedicated control channel for the neighboring access point,
- wherein the process of making the request to switch the channel comprises, when the access point has a specific bandwidth larger than the neighboring access point, requesting the neighboring access point through the dedicated control channel to switch the channel of the neighboring access point,
- wherein the process of changing the selected channel into another channel comprises, when the access point has a specific bandwidth smaller than the neighboring access point, receiving from the neighboring access point through the dedicated control channel a request to switch the selected channel into the another channel,
- wherein the access point and the neighboring access point are coexistence managers (CMs) and the selected channel is a TV white space channel obtained from a coexistence database (CDB), and
- wherein a CM having the specific bandwidth has a higher priority to select the TV white space channel than a CM having the narrower bandwidth.

An access point, comprising:
- a transceiver;
- and
- a processor configured to
- select a specific channel from channels configured to be shared along with a heterogeneous communication scheme,
- determine whether the selected channel interferes with a neighboring access point, and
- perform an avoidance procedure if the selected channel interferes with the neighboring access point,
- wherein the avoidance procedure comprises a process of making a request to switch a channel of the neighboring access point, a process of notifying to the neighboring access point, and a process of changing the selected channel into another channel,
- wherein the neighboring access point uses a heterogeneous communication scheme,
- wherein the process of making the request to switch the channel comprises requesting an entity that is responsible for a control function to switch the channel of the neighboring access point,
- wherein the process of notifying comprises transmitting a signal indicating that the selected channel interferes with the neighboring access point,
- wherein the signal is transmitted through a dedicated control channel for the neighboring access point,
- wherein the process of making the request to switch the channel comprises, when the access point has a specific bandwidth larger than the neighboring access point, requesting the neighboring access point through the dedicated control channel to switch the channel of the neighboring access point,
- wherein the process of changing the selected channel into another channel comprises, when the access point has a specific bandwidth smaller than the neighboring access point, receiving from the neighboring access point through the dedicated control channel a request to switch the selected channel into the another channel,
- wherein the access point and the neighboring access point are coexistence managers (CMs) and the selected channel is a TV white space channel obtained from a coexistence database (CDB), and
- wherein a CM having the specific bandwidth has a higher priority to select the TV white space channel than a CM having the narrower bandwidth.
