Abstract
A Multi-Link access point apparatus uses multiple combinations of link offset information and information of the number of links to notify, by using only a small amount of information, whether a frame is buffered that is addressed to a Multi-Link station apparatus operating in a Power Management mode and information of a link, the use of which is indicated or recommended.
Claims9
An access point apparatus for communicating with a station apparatus, the access point apparatus comprising:
- one or more transmitting circuitries and one or more receiving circuitries configured to communicate with the station apparatus by using multiple links,
- each of the one or more transmitting circuitries and each of the one or more receiving circuitries corresponding to respective ones of the multiple links, wherein:
- any of the one or more transmitting circuitries transmits, to the station apparatus, a frame including a multi-link traffic indication element, the multi-link traffic indication element including a plurality of pieces of first information,
- each of the plurality of pieces of first information is associated with a respective one of a plurality of frequency bands, each frequency band in the plurality of frequency bands being different from other frequency bands in the plurality of frequency bands, and
- each of the plurality of pieces of first information comprises:
- a respective piece of traffic indication bitmap information,
- a respective piece of size information for the respective piece of traffic indication bitmap information, and
- a respective piece of link information for the respective piece of traffic indication bitmap information.
A station apparatus for communicating with an access point apparatus, the station apparatus comprising:
- one or more transmitting circuitries and one or more receiving circuitries configured to communicate with the access point apparatus by using multiple links,
- each of the one or more transmitting circuitries and each of the one or more receiving circuitries corresponding to respective ones of the multiple links, wherein;
- any of the one or more receiving circuitries receives, from the access point apparatus, a frame including a multi-link traffic indication element, the multi-link traffic indication element including a plurality of pieces of first information,
- each of the plurality of pieces of first information is associated with a respective one of a plurality of frequency bands, each frequency band in the plurality of frequency bands being different from other frequency bands in the plurality of frequency bands, and
- each of the plurality of pieces of first information comprises:
- a respective piece of traffic indication bitmap information,
- a respective piece of size information for the respective piece of traffic indication bitmap information, and
- a respective piece of link information for the respective piece of traffic indication bitmap information.
A method performed by an access point apparatus for communicating with a station apparatus, the method comprising:
- communicating with the station apparatus by using multiple links;
- and
- transmitting, to the station apparatus, a frame including a multi-link traffic indication element, the multi-link traffic indication element including a plurality of pieces of first information, wherein:
- each of the plurality of pieces of first information is associated with a respective one of a plurality of frequency bands, each frequency band in the plurality of frequency bands being different from other frequency bands in the plurality of frequency bands, and
- each of the plurality of pieces of first information comprises:
- a respective piece of traffic indication bitmap information,
