Abstract
A communication device establishes multiple wireless links which are used in wireless communication compliant with an IEEE 802.11 series standard and which are used in data communication with a partner device. The communication device collects, from the partner device, power saving information related to power saving operations that respectively correspond to the multiple wireless links and that are performed in the partner device, before a start of frame exchange for a next data communication with the partner device, and using a wireless link, among the multiple wireless links, that is in the enabled state.
Claims10
A communication device comprising:
- one or more processors;
- and
- one or more memories including instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
- establishing multiple wireless links which are used in wireless LAN communication and which are used in data communication with a partner device, wherein a state of each established wireless link can be switched between an enabled state, in which frames can be exchanged over the wireless link, and a disabled state, in which frames cannot be exchanged over the wireless link;
- and
- collecting, from the partner device, power saving information related to power saving operations that respectively correspond to the multiple wireless links and that are performed in the partner device, before a start of frame exchange for a next data communication with the partner device, and using a wireless link, among the multiple wireless links, that is in the enabled state,
- wherein one or more wireless links of the multiple wireless links is in the enabled state for the data communication with the partner device.
A control method of controlling a communication device, the control method comprising:
- establishing multiple wireless links which are used in wireless LAN communication and which are used in data communication with a partner device, wherein a state of each established wireless link is capable of switched between an enabled state, in which frames can be exchanged over the wireless link, and a disabled state, in which frames cannot be exchanged over the wireless link;
- and
- collecting, from the partner device, power saving information related to power saving operations that respectively correspond to the multiple wireless links and that are performed in the partner device, before a start of frame exchange for a next data communication with the partner device, and using a wireless link, among the multiple wireless links, that is in the enabled state,
- wherein one or more wireless links of the multiple wireless links is in the enabled state for the data communication with the partner device.
