Abstract
A communication apparatus for executing communication by establishing connections with another communication apparatus using a plurality of frequency channels transmits or receives, while control communication for collectively controlling communication in the connections using at least two of the plurality of frequency channels is executed, a frame for ending the control communication to or from the other communication apparatus. The frame can include at least two fields each storing information concerning a frequency channel, use of which is stopped in the control communication.
Claims8
A communication apparatus comprising a communication unit configured to execute communication by establishing connections with another communication apparatus using a plurality of frequency channels,
- wherein while control communication for collectively controlling communication in the connections using at least two of the plurality of frequency channels is executed, the communication unit transmits or receives a frame for ending the control communication to or from the other communication apparatus,
- the frame can include at least two fields each storing information concerning a frequency channel, use of which is stopped in the control communication, and
- in a case where the frame does not include the fields, the control communication is ended in all the plurality of frequency channels.
A control method executed by a communication apparatus for executing communication by establishing connections with another communication apparatus using a plurality of frequency channels, comprising:
- transmitting or receiving, while control communication for collectively controlling communication in the connections using at least two of the plurality of frequency channels is executed, a frame for ending the control communication to or from the other communication apparatus,
- wherein the frame can include at least two fields each storing information concerning a frequency channel, use of which is stopped in the control communication, and
- in a case where the frame does not include the fields, the control communication is ended in all the plurality of frequency channels.
A non-transitory computer-readable storage medium that stores a program for causing a computer included in a communication apparatus for executing communication by establishing connections with another communication apparatus using a plurality of frequency channels to:
- transmitting or receiving, while control communication for collectively controlling communication in the connections using at least two of the plurality of frequency channels is executed, a frame for ending the control communication to or from the other communication apparatus,
- wherein the frame can include at least two fields each storing information concerning a frequency channel, use of which is stopped in the control communication, and
- in a case where the frame does not include the fields, the control communication is ended in all the plurality of frequency channels.
