11. The AP of claim 9 , wherein the random-access RUs allocated to one of the selected BSSs is different than the RU on which the frame is transmitted for that BSS.

12. The AP of claim 9 , wherein the frames are aggregated in a downlink multi-user physical layer protocol data unit (DL MU PPDU).

13. The AP of claim 9 , wherein execution of the instructions causes the AP to further:

allocate additional random-access RUs to the remaining BSSs of the plurality of BSSs; and

transmit a trigger frame indicating the allocation of additional random-access RUs to the remaining BSSs.

14. The AP of claim 13 , wherein the trigger frame includes an AID value of 2047.

15. The AP of claim 9 , wherein the plurality of BSSs includes at least a transmitted BSS and a non-transmitted BSS, and wherein execution of the instructions causes the AP to further:

allocate additional random-access RUs to the non-transmitted BSS:

transmit, via the transmitted BSS, a multi-BSS trigger frame indicating the allocation of additional random-access RUs to the non-transmitted BSS, wherein the multi-BSS trigger frame includes an AID value corresponding to a BSSID index of the non-transmitted BSS; and

receive uplink data, on the additional random-access RUs allocated by the multi-BSS trigger frame, from one or more wireless devices belonging to the non-transmitted BSS.

16. The AP of claim 9 , wherein the one or more random-access RUs comprise contention-based resources to be shared only by wireless devices belonging to the selected BSSs.

17. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of an access point (AP), cause the AP to perform operations comprising:

selecting two or more basic service sets (BSSs) from a plurality of BSSs, wherein the selected two or more BSSs is a subset of the plurality of BSSs;

allocating one or more random-access resource units (RUs) to each selected BSS of the selected BSSs; and

transmitting, for each selected BSS of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS, wherein each of the frames comprises a trigger frame including an association identification (AID) value of zero and each of the frames is transmitted on a different RU.

18. The non-transitory computer-readable medium of claim 17 , wherein each of the plurality of BSSs is operated by the AP, and wherein the one or more random-access RUs comprise contention-based resources to be shared only by wireless devices belonging to the selected BSSs.

19. The non-transitory computer-readable medium of claim 17 , wherein the frames are aggregated in a downlink multi-user physical layer protocol data unit (DL MU PPDU).

20. The non-transitory computer-readable medium of claim 17 , wherein execution of the instructions causes the AP to perform operations further comprising:

allocating additional random-access RUs to the remaining BSSs of the plurality of BSSs; and

transmitting a trigger frame indicating the allocation of additional random-access RUs to the remaining BSSs.
