Abstract
A communication apparatus that performs communication compliant with IEEE 802.11 standard series performs communication with another communication apparatus using a first channel access method that uses at least a Primary channel of one link and a second channel access method that, in a case where the Primary channel is in a busy state, uses a Non-Primary channel different from the Primary channel, and does not use the Primary channel, in a time period in which communication is being executed with a first communication apparatus using the second channel access method, in a case where the Primary channel becomes available for use, executing a first control, a second control, a third control, or fourth control.
Claims18
A communication apparatus that performs communication compliant with IEEE 802.11 standard series, comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processor that executes the instructions, the instructions, when executed, causing the communication apparatus to perform operations comprising:
- performing communication with another communication apparatus using a first channel access method that uses at least a Primary channel of one link and a second channel access method that, in a case where the Primary channel is in a busy state, uses a Non-Primary channel different from the Primary channel from among a plurality of channels included in the link and does not use the Primary channel, and
- in a time period in which communication is being executed with a first communication apparatus using the second channel access method, in a case where the Primary channel becomes available for use, executing a first control to transition an operating status of the communication apparatus for the Primary channel to a predetermined status, a second control to transition a status of the Primary channel to a predetermined status, a third control to transmit a predetermined signal to the first communication apparatus executing communication using the Non-Primary channel, or fourth control to end communication with the first communication apparatus executed using the second channel access method.
A communication method executed by a communication apparatus that performs communication compliant with IEEE 802.11 standard series with another communication apparatus using a first channel access method that uses at least a Primary channel of one link and a second channel access method that, in a case where the Primary channel is in a busy state, uses a Non-Primary channel different from the Primary channel from among a plurality of channels included in the link and does not use the Primary channel, the communication method comprising:
- in a time period in which communication is being executed with a first communication apparatus using the second channel access method, in a case where the Primary channel becomes available for use, executing a first control to transition an operating status of the communication apparatus for the Primary channel to a predetermined status, a second control to transition a status of the Primary channel to a predetermined status, a third control to transmit a predetermined signal to the first communication apparatus executing communication using the Non-Primary channel, or fourth control to end communication with the first communication apparatus executed using the second channel access method.
A non-transitory computer readable storage medium that stores a program that causes, when the program is executed, a communication apparatus, which performs communication compliant with IEEE 802.11 standard series with another communication apparatus using a first channel access method that uses at least a Primary channel of one link and a second channel access method that, in a case where the Primary channel is in a busy state, uses a Non-Primary channel different from the Primary channel from among a plurality of channels included in the link and does not use the Primary channel, to perform:
- in a time period in which communication is being executed with a first communication apparatus using the second channel access method, in a case where the
- Primary channel becomes available for use, executing a first control to transition an operating status of the communication apparatus for the Primary channel to a predetermined status, a second control to transition a status of the Primary channel to a predetermined status, a third control to transmit a predetermined signal to the first communication apparatus executing communication using the Non-Primary channel, or fourth control to end communication with the first communication apparatus executed using the second channel access method.
