1. A communication device conforming to a standard of an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series, comprising:
one or more processors; and
one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the communication device to:
determine two or more frequency bands that the communication device can use for communication;
generate a frame in which usable frequency band information that indicates frequency bands that the communication device can use for communication is included; and
transmit the generated frame,
wherein the frame includes a Multi-band element for notifying the usable frequency band information, wherein the usable frequency band information indicates one or more frequency bands included in the determined two or more frequency bands, and the one or more frequency bands is obtained by omitting a frequency band used for transmission of the frame from the determined two or more frequency bands, and the usable frequency band is included in a Band ID field for identifying respective one of the one or more frequency bands in the Multi-band element, and
wherein in a case where the frequency band used for transmission of the frame is a 6 GHz band, information indicating frequency bands other than 6 GHz band is included in the Band ID field, and in a case where the frequency band used for transmission of the frame is not a 6 GHz band, information indicating a 6 GHz frequency band is included in the Band ID field.
