Abstract
An access point (AP) may prioritize the allocation of uplink resources between multiple basic service sets (BSSs). In some aspects, the AP may select one of a plurality of BSSs, may allocate one or more random-access resource units (RUs) to only the selected BSS, and may transmit, for each of the selected BSSs, a respective frame indicating the random-access RUs allocated to that BSS. Wireless devices belonging to the selected BSS may contend for access to the random-access RUs allocated by the frame, and then transmit uplink data using the random-access RUs.
Claims30
A method performed at wireless station (STA) belonging to a first basic service set (BSS), comprising:
- receiving, from an access point (AP) operating a plurality of BSSs that includes the first BSS, a physical layer protocol data unit (PPDU) carrying one or more trigger frames, each trigger frame allocating one or more random-access resource units (RUs) to STAs associated with a respective BSS of a subset of the plurality of BSSs, each trigger frame including an association identifier (AID) value of zero;
- and
- transmitting uplink (UL) data to the AP over the one or more random-access RUs allocated to the STAs associated with the first BSS responsive to the AID value of zero.
A wireless communication device belonging to a first basic service set (BSS), comprising:
- one or more processors;
- and
- a memory storing instructions that, when executed by the one or more processors, cause the wireless communication device to:
- receive, from an access point (AP) operating a plurality of BSSs that includes the first BSS, a physical layer protocol data unit (PPDU) carrying one or more trigger frames, each trigger frame allocating one or more random-access resource units (RUs) to wireless stations (STAs) associated with a respective BSS of a subset of the plurality of BSSs, each trigger frame including an association identifier (AID) value of zero;
- and
- transmit uplink (UL) data to the AP over the one or more random-access RUs allocated to the STAs associated with the first BSS responsive to the AID value of zero.
