Access point apparatus, station apparatus, and radio communication system
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.
1 . 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.
2 . The access point apparatus according to claim 1 , wherein the respective piece of link information indicates whether links, as targets for the respective piece of traffic indication bitmap information, includes millimeter waves and/or micrometer waves.
3 . The access point apparatus according to claim 1 , wherein the frame includes a respective piece of traffic indication bitmap information for links including millimeter waves in addition to a respective piece of traffic indication bitmap information for links including micrometer waves.
4 . 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.
5 . The station apparatus according to claim 4 , wherein the respective piece of link information indicates whether links, as targets for the respective piece of traffic indication bitmap information, includes millimeter waves and/or micrometer waves.
6 . The station apparatus according to claim 4 , wherein the frame includes a respective piece of traffic indication bitmap information for links including millimeter waves in addition to a respective piece of traffic indication bitmap information for links including micrometer waves.
7 . 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,
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.
8 . The method according to claim 7 , wherein the respective piece of link information indicates whether links, as targets for the respective piece of traffic indication bitmap information, includes millimeter waves and/or micrometer waves.
9 . The method according to claim 7 , wherein the frame includes a respective piece of traffic indication bitmap information for links including millimeter waves in addition to a respective piece of traffic indication bitmap information for links including micrometer waves.
