Abstract

This disclosure describes systems, methods, and devices related to intra-basic service set (BSS) signaling for multiple access points (APs). A device may determine one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS. The device may include, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs. The device may include, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device. The device may cause to send the first frame a first station device of one or more station devices. The device may cause to send the second frame to a second station device of the one or more station devices.

First claim

What is claimed is:

1 . A device, the device comprising processing circuitry coupled to storage, the processing circuitry configured to:
determine one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS; include, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs; include, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device; cause to send the first frame a first station device of one or more station devices; and cause to send the second frame to a second station device of the one or more station devices.

2 . The device of claim 1 , wherein a basic service set identification (BSSID) of the device is determined from the set of multiple BSSs, and wherein the BSSID is a control BSSID.

3 . The device of claim 1 , wherein the set of the multiple BSSs is a co-located basic service set identification (BSSID) set or a co-hosted BSSID set.

4 . The device of claim 1 , wherein the first frame does not contain a multiple BSSID element.

5 . The device of claim 1 , wherein the processing circuitry is further configured to determine a resource unit intended for an unassociated STA.

6 . The device of claim 1 , wherein the one or more APs in the set of multiple BSSs have a same BSS color.

7 . The device of claim 1 , wherein the device is in a first BSS.

8 . The device of claim 7 , wherein the processing circuitry is further configured to cause to send a control frame to solicit response from the second station device in a second BSS of the set of the multiple BSSs, wherein the second BSS is different from the first BSS.

9 . The device of claim 7 , wherein a number n of least significant bits (LSBs) of the control BSSID is in indicated in the first frame, and wherein n is indicated by the indicator of the set of multiple BSSs.

10 . The device of claim 1 , wherein the AID value is derived from a range of AID values between 0 and 2 n −1, wherein n is a positive integer, and wherein 2 n is a maximum number of BSSIDs in the set of multiple BSSs.

11 . The device of claim 10 , wherein each BSS in the set of the multiple BSSs has a specific AID value from a range of AID values between 0 and 2 n −1.

12 . The device of claim 10 , wherein each associated STAs of the BSS in the set of the multiple BSSs has a specific AID value from a range of AID values larger than 2 n −1.

13 . The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals.

14 . The device of claim 13 , further comprising an antenna coupled to the transceiver.

15 . A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
determining one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS; including, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs; including, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device; causing to send the first frame a first station device of one or more station devices; and causing to send the second frame to a second station device of the one or more station devices.

16 . The non-transitory computer-readable medium of claim 15 , wherein a basic service set identification (BSSID) of the device is determined from the set of multiple BSSs, and wherein the BSSID is a control BSSID.

17 . The non-transitory computer-readable medium of claim 15 , wherein the set of the multiple BSSs is a co-located basic service set identification (BSSID) set or a co-hosted BSSID set.

18 . The non-transitory computer-readable medium of claim 15 , wherein the first frame does not contain a multiple BSSID element.

19 . A method comprising:
determining, by one or more processors, one or more access points (APs), wherein the one or more APs are in a set of multiple basic service sets (BSSs) identified as intra-BSS; including, in a first frame, a high-efficiency operation element comprising a bit associated with an indicator of the set of multiple BSSs; including, in a second frame, an association identification (AID) value, wherein the AID value is associated with the device; causing to send the first frame a first station device of one or more station devices; and causing to send the second frame to a second station device of the one or more station devices.

20 . The method of claim 27 , wherein a basic service set identification (BSSID) of the device is determined from the set of multiple BSSs, and wherein the BSSID is a control BSSID.
