Wireless communication node scanning and association
Systems, devices, and techniques are described for communication node scanning and association in a wireless communication network. An illustrative method includes receiving, via a first channel, identifying information that identify a plurality of communication nodes that are configured to communicate via at least a second channel. The illustrative method further includes initiating communication, via at least the second channel, with a communication node based, at least in part, on the identifying information.
1. A method for wireless communication, comprising:
receiving, by a station (STA), a wake-up element including information that identifies wake-up channels on which access points (APs) transmit wake-up frames,
wherein the information comprises an identifier that identifies a virtual basic service set (BSS) group of at least one AP associated with a particular wake-up channel,
wherein the virtual BSS group corresponds to a set of one or more BSSs that provide a logical or physical contiguous coverage region to the STA,
wherein the virtual BSS group includes interconnected BSSs that appear as a single BSS to a logical link control (LLC) layer at the STA,
wherein the APs comprise the at least one AP and the wake-up channels comprise the particular wake-up channel, and
wherein the particular wake-up channel is indicated by wake-up parameters of the at least one AP in the information;
scanning, by the STA, on the particular wake-up channel identified by the information, wherein timing for a wake-up operation is determined by the at least one AP by transmitting wake-up beacon frames, wherein the at least one AP is associated with the STA; and
initiating, by the STA, a frame exchange with its associated at least one AP to use a power-saving mode.
2. The method of claim 1 , wherein the at least one AP is transmitting the wake-up element to the STA, or wherein the at least one AP is a neighboring AP.
3. The method of claim 1 , wherein the particular wake-up channel is a primary channel of the at least one AP.
4. The method of claim 1 , wherein the wake-up beacon frames are scheduled by the at least one AP on a primary channel of the at least one AP.
5. The method of claim 1 , wherein the wake-up element is included in a wake-up beacon frame or a Probe Response frame received by the STA.
6. The method of claim 1 , wherein a Basic Service Set Identifier (BSSID) of the at least one AP is indicated by the wake-up parameters of the at least one AP in the information.
7. The method of claim 1 , wherein a compressed service set identifier (SSID) of the at least one AP is indicated by the wake-up parameters of the at least one AP in the information.
8. A station (STA) comprising:
a memory that stores instructions that upon execution by a processor causes the processor to implement a method, the processor is configured to:
receive a wake-up element including information that identifies wake-up channels on which access points (APs) transmit wake-up frames,
wherein the information comprises an identifier that identifies a virtual basic service set (BSS) group of at least one AP associated with a particular wake-up channel,
wherein the virtual BSS group corresponds to a set of one or more BSSs that provide a logical or physical contiguous coverage region to the STA,
wherein the virtual BSS group includes interconnected BSSs that appear as a single BSS to a logical link control (LLC) layer at the STA,
wherein the APs comprise the at least one AP and the wake-up channels comprise the particular wake-up channel, and
wherein the particular wake-up channel is indicated by wake-up parameters of the at least one AP in the information;
scan on the particular wake-up channel identified by the information, wherein timing for a wake-up operation is determined by the at least one AP by transmitting wake-up beacon frames, wherein the at least one AP is associated with the STA; and
initiate a frame exchange with its associated at least one AP to use a power-saving mode.
9. The STA of claim 8 , wherein the at least one AP is transmitting the wake-up element to the STA, or wherein the at least one AP is a neighboring AP.
10. The STA of claim 8 , wherein the particular wake-up channel is a primary channel of the at least one AP.
11. The STA of claim 8 , wherein the wake-up beacon frames are scheduled by the at least one AP on a primary channel of the at least one AP.
12. The STA of claim 8 , wherein the wake-up element is included in a wake-up beacon frame or a Probe Response frame received by the STA.
13. The STA of claim 8 , wherein a Basic Service Set Identifier (BSSID) of the at least one AP is indicated by the wake-up parameters of the at least one AP in the information.
14. The STA of claim 8 , wherein a compressed service set identifier (SSID) of the at least one AP is indicated by the wake-up parameters of the at least one AP in the information.
15. A non-transitory computer-readable medium having stored thereon computer-executable instructions for:
receiving, by a station (STA), a wake-up element including information that identifies wake-up channels on which access points (APs) transmit wake-up frames,
wherein the information comprises an identifier that identifies a virtual basic service set (BSS) group of at least one AP associated with a particular wake-up channel,
wherein the virtual BSS group corresponds to a set of one or more BSSs that provide a logical or physical contiguous coverage region to the STA,
wherein the virtual BSS group includes interconnected BSSs that appear as a single BSS to a logical link control (LLC) layer at the STA,
wherein the APs comprise the at least one AP and the wake-up channels comprise the particular wake-up channel, and
wherein the particular wake-up channel is indicated by wake-up parameters of the at least one AP in the information;
scanning, by the STA, on the particular wake-up channel identified by the information, wherein timing for a wake-up operation is determined by the at least one AP by transmitting wake-up beacon frames, wherein the at least one AP is associated with the STA; and
initiating, by the STA, a frame exchange with its associated at least one AP to use a power-saving mode.
16. The non-transitory computer-readable medium of claim 15 , wherein the at least one AP is transmitting the wake-up element to the STA, or wherein the at least one AP is a neighboring AP.
17. The non-transitory computer-readable medium of claim 15 , wherein the particular wake-up channel is a primary channel of the at least one AP.
18. The non-transitory computer-readable medium of claim 15 , wherein the wake-up beacon frames are scheduled by the at least one AP on a primary channel of the at least one AP.
