Assignee: CANON KABUSHIKI KAISHA
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A communication apparatus comprising:
at least one memory that stores instructions; and
at least one processor that executes the instructions, the instructions, when executed, causing the communication apparatus to perform operations comprising:
setting a transmission interval of a WUR (Wake-UP Radio) frame;
attempting a process for transmitting the WUR frame periodically based on the set transmission interval to an apparatus operating in a second operation mode among a plurality of operation modes including a first operation mode and the second operation mode, the first operation mode using a first wireless communication interface, the second operation mode not using the first wireless communication interface and using a second wireless communication interface operable with lower power consumption than the first wireless communication interface, the WUR frame causing the apparatus to transition from the second operation mode to the first operation mode;
determining whether transmitting a request signal is prioritized based on whether the set transmission interval is equal to or longer than a predetermined value; and
deciding a parameter in the request signal, based on a result of the determination, the parameter being used to avoid an access conflict in a wireless communication band,
wherein the WUR frame is transmitted when a transmission opportunity is acquired by the communication apparatus based on the decided parameter.
