Abstract

Methods, systems, and devices for wireless communications are described for coordination between multiple access points (APs) for communications within a transmission opportunity (TxOP). A first AP may gain channel access for a TxOP, and may coordinate with at least a second AP to allow both the first AP and the second AP to transmit and receive wireless communications during the TxOP. The first AP, upon gaining channel access following a successful contention-based channel access procedure, may initiate a scheduling phase with the second AP to schedule of resources within the TxOP for the first and second APs. The first AP may initiate a multi-AP coordinated transmission phase following the scheduling phase, during which both the first AP and second AP may communicate with one or more associated STAs.
