Communication apparatus, communication method, and non-transitory computer-readable-storage medium

A communication apparatus capable of performing communication with another communication apparatus using one communication link including a first primary channel as a common channel used by said another communication apparatus for determining whether or not a transmission to the communication apparatus can be performed and one or more second channels different from the first primary channel, 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:
• obtaining, from said another communication apparatus, a UHR (Ultra High Reliability) Capabilities element specified by IEEE 802.11 standard series including capability information indicating whether a Non-Primary Channel Access, NPCA, operation for performing communication using one of the one or more second channels as a second primary channel and not using the first primary channel is supported by said another communication apparatus, and obtaining, from said another communication apparatus, a UHR Operation element that includes a field for specifying a channel number of the second primary channel used by said another communication apparatus and the communication apparatus to perform the NPCA operation;
• and
• performing communication in accordance with the capability information with said another communication apparatus using one or more channels including any of the first primary channel and the second primary channel.

A non-transitory computer-readable-storage medium that stores a program that causes, when the program is executed, a communication apparatus capable of performing communication with another communication apparatus using one communication link including a first primary channel as a common channel used by said another communication apparatus for determining whether or not a transmission to the communication apparatus can be performed and one or more second channels different from the first primary channel to perform:

• notifying, using a UHR (Ultra High Reliability) Capabilities element specified by IEEE 802.11 standard series, said another communication apparatus of capability information indicating whether a Non-Primary Channel Access, NPCA, operation for performing communication using one of the one or more second channels as a second primary channel and not using the first primary channel is supported and notifying, using a UHR Operation element that includes a field for specifying a channel number of the second primary channel used by the communication apparatus and said another communication apparatus to perform the NPCA operation, said another communication apparatus of the channel number of the second primary channel;
• and
• performing communication in accordance with the capability information with said another communication apparatus using one or more channels including any of the first primary channel and the second primary channel.
