Abstract
A communication apparatus capable of performing wireless communication with another apparatus by simultaneously using a first link and a second link performs, based on reception, from a first other apparatus, of a predetermined frame for executing communication by simultaneously using the first link and the second link, transmission, to the first other apparatus, of information indicating allocation of radio resources in the first link and the second link to the first other apparatus, and transmission, to a second other apparatus different from the first other apparatus, of information indicating allocation of the radio resources in one of the first link and the second link to the second other apparatus.
Claims19

- 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 one or more processors to function as:
- a communication unit configured to establish at least a first link using a first frequency channel and a second link using a second frequency channel with one or more other apparatuses operating as a station compliant with the IEEE 802.11 standard, and performing wireless communication;
- and
- a control unit configured to control, based on reception on the first frequency channel, from a first other apparatus operating as a station compliant with the IEEE 802.11 standard, of a predetermined frame for requesting transmission of a trigger frame for executing communication by simultaneously using the first frequency channel and the second frequency channel, the communication unit to transmit on the first frequency channel, to the first other apparatus, a first trigger frame including information indicating allocation of radio resources of the first frequency channel to the first other apparatus but not to a second other apparatus different from the first other apparatus that operates as a station compliant with the IEEE 802.11 standard and does not transmit the predetermined frame, and to transmit, to the first other apparatus and the second other apparatus, a second trigger frame including information indicating allocation of the radio resources and the second frequency channel to the first other apparatus and the second other apparatus.
A communication apparatus operating as a station compliant with an IEEE 802.11 standard, comprising:
- one or more processors;
