Abstract
A communication apparatus that performs communication complying with the IEEE802.11 standard series with a partner apparatus using a plurality of radio links performs control such that when a predetermined frame that is a group addressed frame is transmitted in a first radio link of the plurality of radio links, a frame addressed to the communication apparatus does not arrive in a second radio link different from the first radio link of the plurality of radio links.
Claims13
A communication apparatus that performs communication complying with IEEE802.11 standard series with a partner apparatus using a plurality of radio links, the communication apparatus 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:
- controlling, in a case where a predetermined frame that is a group addressed frame is to be transmitted in a first radio link of the plurality of radio links, the communication apparatus to execute control processing that includes transmission of a frame in the second radio link to ensure a transmission opportunity during a period in which the predetermined frame is transmitted in the first radio link,
- wherein a value of a Duration field in the frame transmitted in the second radio link is set to a period corresponding to the period in which the predetermined frame is transmitted in the first radio link.
A control method executed by a communication apparatus that performs communication complying with the IEEE802.11 standard series with a partner apparatus using a plurality of radio links, comprising:
- controlling, in a case where a predetermined frame that is a group addressed frame is to be transmitted in a first radio link of the plurality of radio links, the communication apparatus to execute a control processing for preventing a frame addressed to the communication apparatus does not arrive in a second radio link different from the first radio link of the plurality of radio links,
- wherein the control processing includes transmits a frame in the second radio link to ensure a transmission opportunity during a period in which the predetermined frame is transmitted in the first radio link, and
- wherein a value of a Duration field in the frame transmitted in the second radio link is set to a period corresponding to the period in which the predetermined frame is transmitted in the first radio link.
A non-transitory computer-readable storage medium that stores a program configured to cause a computer included in a communication apparatus to perform operations comprising:
- controlling, in a case where a predetermined frame that is a group addressed frame is to be transmitted in a first radio link of the plurality of radio links, the communication apparatus to execute a control processing for preventing a frame addressed to the communication apparatus does not arrive in a second radio link different from the first radio link of the plurality of radio links,
- wherein the control processing includes transmits a frame in the second radio link to ensure a transmission opportunity during a period in which the predetermined frame is transmitted in the first radio link, and
- wherein a value of a Duration field in the frame transmitted in the second radio link is set to a period corresponding to the period in which the predetermined frame is transmitted in the first radio link.
