Communication apparatus, communication method, and storage medium
A link is established between communication apparatuses 102 and 103 that can execute multi-link communication complying with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard via a frequency channel, and a media access control (MAC) frame in which information regarding a second link different from an established first link is included later than a field in which information regarding a service set identifier (SSID) is stored is communicated between the communication apparatuses 102 and 103.
1 . A communication apparatus that can execute multi-link communication complying with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard by a first link using a first frequency channel and a second link using a second frequency 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:
communicating a media access control (MAC) frame including a first element including information regarding the second link and a second element including information regarding a service set identifier (SSID) in the first frequency channel, the MAC frame including a header and a body, the first element and the second element being included in the body, and the first element being arranged later than the second element in the body,
wherein the first element includes an Element ID field and a Length field, and the Element ID field is a field positioned in front among a plurality of fields included in the first element.
2 . The communication apparatus according to claim 1 , wherein the information regarding the second link includes identification information regarding the second link.
3 . The communication apparatus according to claim 2 , wherein the identification information is a basic service set identifier (BSSID) regarding the second link.
4 . The communication apparatus according to claim 2 , wherein the identification information is a Link ID of the second link.
5 . The communication apparatus according to claim 1 , wherein the information regarding the second link is included later than an HE 6-GHz Band Capabilities element in the MAC frame.
6 . The communication apparatus according to claim 1 , wherein the information regarding the second link is included later than a Supported Rates and BSS Membership Selectors element in the MAC frame.
7 . The communication apparatus according to claim 1 , wherein the first element includes a first field including information regarding the first link and the information regarding the second link, and the first field is arranged later than the Length field.
8 . A communication method that can execute multi-link communication complying with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard by a first link using a first frequency channel and a second link using a second frequency channel, comprising:
communicating a media access control (MAC) frame including a first element including information regarding the second link and a second element including information regarding a service set identifier (SSID) in the first frequency channel, the MAC frame including a header and a body, the first element and the second element being included in the body, and the first element being arranged later than the second element in the body,
wherein the first element includes an Element ID field and a Length field, and the Element ID field is a field positioned in front among a plurality of fields included in the first element.
9 . A non-transitory computer-readable storage medium for storing a program for causing a computer to execute a communication method that can execute multi-link communication complying with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 series standard comprising:
communicating a media access control (MAC) frame including a first element including information regarding the second link and a second element including information regarding a service set identifier (SSID) in the first frequency channel, the MAC frame including a header and a body, the first element and the second element being included in the body, and the first element being arranged later than the second element in the body,
wherein the first element includes an Element ID field and a Length field, and the Element ID field is a field positioned in front among a plurality of fields included in the first element.
