Logic to generate, by an access point (AP) station (STA), a medium access control (MAC) resource assessment trigger frame to transmit during a first transmission opportunity (TxOP), the MAC resource assessment trigger frame to allocate a portion of the first TxOP to a first STA and to request a first resource assessment from a first group of STAs for evaluation by the first STA, the first resource assessment to assess peer-to-peer (P2P) data transfers between the first group of STAs and the first STA. Logic to cause transmission of the MAC resource assessment trigger frame to the first STA and the first group of STAs. And logic to receive one or more short term resource assessment frames from the first group of STAs, the one or more short term resource assessment frames each comprising an indication of resources for a data transfer.

Methods and arrangements for resource assessment

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.
