- AP access point
- MAC medium access control
- Example embodiments of the present disclosure relate to systems, methods, and devices for access point (AP) identification (ID) allocation to enable cooperation between one or more APs when communicating with each other and with one or more station devices, for example, allocating resources to the one or more station devices (STAs).
- AP access point
- STA station devices
- an AP ID allocation system may facilitate one or more packets (or one or more frames) exchanges to enable an AP to obtain an ID from the adjacent the one or more packets exchanges has a lower complexity than the association procedure.
- the association procedure requires authentication and encryption between the devices, which makes it more complex to establish.
- an AP ID allocation system exchanging a limited number of packets (e.g., four packets or less) in order to assign AP_IDs to adjacent APs.
- the AP ID allocation system may facilitate allocating an AP_ID using the one or more packets exchanges between adjacent APs.
- An initiating AP may determine an adjacent AP in a cooperative network based at least in part on one or more factors, such as, distance, received signal strength indicator (RSSI), signal to noise ratio (SNR), etc.
- the initiating AP may send a request (e.g., an AP_ID request packet) to an adjacent AP (e.g., a responding AP).
- the responding AP may respond to the AP_ID request by sending an acknowledgment packet to the initiating AP.
- the responding AP may allocate an AP_ID to the initiating AP.
- the responding AP may then send an AP_ID response packet to the initiating AP, where the AP_ID response packet may contain the AP_ID that is allocated to the initiating AP.
- the initiating AP may then respond with an acknowledgment packet to be sent to the responding AP.
- a BSS color may be included in a signaling field (e.g., HE-SIG-A ) of an HE frame that may be received from another AP that may be within listening/reception distance.
- the initiating device may use their BSS color to determine whether the BSS color in the received packet is its own BSS color or not. For example, when an AP receives an HE packet, if the BSS color of the packet is different to the AP's own BSS color, then the AP need to check whether the BSS color is in the lookup table. If the BSS color is in the table, this may indicate that the packet is from an adjacent AP. In that case, the AP may need to decode the data payload of the packet.

- the initiating AP 203 may send an AP_ID request 210 to the responding AP 205 in order to get an AP_ID assignment from the responding AP 205.
- the initiating AP 203 may start a timer when it sends the request for an AP_ID (e.g., AP_ID request packet 210) to the responding AP 205. If the timer expires, the initiating AP 203 may determine that the responding AP 205 has not received the packet. In that case, the initiating AP 203 may resend the request to the responding AP 205. However, if the initiating AP 203 receives a response (e.g., AP_ID responding packet 214) from the responding AP 205 comprising an indication of the allocated AP_ID before the timer expiry then the initiating AP 203 may determine that the responding AP 205 received the request (e.g., AP_ID request packet 210).

- the receiving AP 203 may determine that a packet is HE or non-HE based on information included in the packet' s PHY preamble.
- a BSS color is a field included in the preambles of HE Wi-Fi frames but not in non- HE packets. In case there is a BSS color included in the PHY preamble of the received packet, the receiving AP 203 may read the BSS color.
- the BSS color indicates whether the received HE frame is from the device's own BSS.
- a BSS color may be included in a signaling field (e.g., HE-SIG-A) of an HE frame that may be received from another AP that may be within listening or detection/reception distance.
- the receiving AP 203 may determine whether the received BSS color is its own BSS color. For example, when the receiving AP 203 receives an HE packet, if the BSS color of the packet is different from the its own BSS color, then the receiving AP 203 may need to check whether the BSS color is in the lookup table to determine whether an AP_ID has been assigned to it by the transmitting AP 205.
- this may indicate that the packet is from an adjacent AP (e.g., transmitting AP 205). In that case, the AP may need to decode the data payload of the packet to determine if there is any data included in a user info field that may be intended for it.
- the receiving AP 203 can use the AP_ID to check whether the packet is intended for it. Then the AP may process the received packet and respond to it by sending a response packet.
- the receiving AP 203 may include its AP_ID to indicate that it is the transmitter of the response packet.
- the TA field in the response may be the same as the AP_ID or BSSID, where the AP_ID corresponds to the transmitting AP 205.
- the AP ID may be assigned or allocated during FTM or 802.11az negotiation or by a four packet exchange sequence (or two packet exchange sequence if no acknowledgement is needed after the request or the response packets).

- the initiator sends FTM request to responder, and responder sends Ack, and then responder sends FTM response and the initiator sends Ack.
- One variant to the AP ID allocation protocol is to add the AP ID request and response fields in the FTM request and FTM response frames, such that the AP ID can be allocated in the negotiation phase of FTM or 802.1 laz.

- the AP ID allocation device 519 may facilitate that the initiating AP may maintain a lookup table to store the AP_IDs that it may receive from responding or adjacent APs over time.
- the lookup table may serve to determine whether a packet or frame is intended for it based on the AP_ID included in the packet or frame.
- the initiating AP may also store the BSSID and the BSS color of the responding AP in the lookup table.
- the AP ID allocation device 519 may facilitate that an AP may analyze a received packet or frame (e.g., a HE packet or frame or a non-HE packet or frame) based on a BSS color.
- the AP may determine that a packet is an HE or non-HE, based on information included in the packet's PHY preamble.
- a BSS color is a field included in the preambles of HE Wi-Fi frames.
- a device e.g., an AP
- the BSS color indicates whether the received in the HE frame is in the device's own BSS.
- a BSS color may be included in a signaling field (e.g., HE-SIG-A) of an HE frame that may be received from another AP that may be within listening/reception distance.
- the initiating device may use their BSS color to determine whether the BSS color in the received packet is its own BSS color or not. For example, when an AP receives an HE packet, if the BSS color of the packet is different to the AP's own BSS color, then the AP need to check whether the BSS color is in the lookup table. If the BSS color is in the table, this may indicate that the packet is from an adjacent AP. In that case, the AP may need to decode the data payload of the packet.
- the AP ID allocation device 519 may facilitate that if the AP receives a non-HE packet, it may need to decode the medium access control (MAC) payload of the received non- HE packet in order to determine whether the packet is intended for it since there is no BSS color indication in a non-HE packet. For example after decoding the MAC payload, the AP may check whether the transmitter address (TA) field of the packet is found in the AP's lookup table. In that sense, the AP that received the non-HE packet would know if an entry exists for the AP that transmitted the non-HE packet. If an entry is found, a corresponding AP_ID may be also found in the lookup table.
- MAC medium access control
- the AP can use the AP_ID to check whether the packet is intended for it. Then the AP may process the received packet and respond to it. In its response, the AP may use the AP_ID to indicate that it is the transmitter of the response. For example, the TA field in the response may be the same as the AP_ID or BSSID.
- machine-readable medium 522 is illustrated as a single medium, the term “machine-readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 524.
