An access point (AP) is configured for trigger-based peer-to-peer (TB P2P) operation with at least two peer stations (P2P1) and (P2P2) in which the AP (API) is operating as a coordinator. The AP may be configured to encode a trigger frame (AP TF) for transmission to reserve channel resources for two or more P2P transfers and identify times for each of the P2P transfers and may indicate an allocation of channel resources to a first of the peer stations (P2P1) for a first of the P2P transfers and to a second of the peer stations (P2P2) for a second of the P2P transfers. During the allocation for the first P2P transfer, the AP may decode a null data packet (NDP) frame for channel sounding received from the first peer station (P2P1). The AP may also encode a TB physical layer protocol data unit (PPDU) in accordance with a multi-user orthogonal frequency division multiple access (MU OFDMA) frame format a transmission to the first peer station (P2P1) in accordance with an uplink multi-user multiple-input multiple output (UL MU MIMO) technique.
