Abstract
A method and apparatus for allocating a channel in a wireless local area network (WLAN) is disclosed. The method includes receiving a first frame including scheduling information with respect to a first interval from a second access point, generating a second frame including resource related information required for transmission and reception during a second interval which is continuous to the first interval, and transmitting the second frame to the second access point. Accordingly, performance of the WLAN can be improved.
Claims18
A method of setting a channel performed at a first access point, the method comprising:
- receiving a first frame including scheduling information with respect to an interval #n from a second access point supporting a plurality of channels;
- generating a second frame including resource related information required for transmission and reception during an interval #(n+1) which is continuous to the interval #n;
- transmitting the second frame to the second access point,
- wherein, when the interval #n is allocated for the first access point and a third access point, the scheduling information indicates at least one channel except for channels allocated to the third access point among the plurality of channels, and communications between the first access point and at least one terminal which is accessed to the first access point are performed using the at least one channel indicated by the scheduling information in the interval #n, and
- wherein the resource related information indicates necessary resources for communications of the first access point in the interval #(n+1), and n is an integer of one or more.
A method of managing a channel performed at a second access point supporting a plurality of channels, the method of managing the channel comprising:
- generating a first frame including scheduling information with respect to an interval #n;
- transmitting the first frame to a first access point;
- and
- receiving a second frame including resource related information required for transmission and reception through an interval #(n+1) which is continuous to the interval #n from the first access point,
- wherein, when the interval #n is allocated for the first access point and a third access point, the scheduling information indicates at least one channel except for channels allocated to the third access point among the plurality of channels, and communications between the first access point and at least one terminal which is accessed to the first access point are performed using the at least one channel indicated by the scheduling information in the interval #n, and
- wherein the resource related information indicates necessary resources for communications of the first access point in the interval #(n+1), and n is an integer of one or more.
A first access point, comprising:
- a processor;
- and
- a memory configured to store at least one command which is executed through the processor,
- wherein the at least one command enables the processor to execute an operation comprising:
- receiving a first frame including scheduling information with respect to an interval #n from a second access point supporting a plurality of channels;
- generating a second frame including resource related information required for transmission and reception through an interval #(n+1) which is continuous to the interval #n;
- and
- transmitting the second frame to the second access point,
- wherein, when the interval #n is allocated for the first access point and a third access point, the scheduling information indicates at least one channel except for channels allocated to the third access point among the plurality of channels, and communications between the first access point and at least one terminal which is accessed to the first access point are performed using the at least one channel indicated by the scheduling information in the interval #n, and
- wherein the resource related information indicates necessary resources for communications of the first access point in the interval #(n+1), and n is an integer of one or more.
