Methods and arrangements for resource assessment

A non-transitory computer-readable medium, comprising instructions, which when executed by a processor, cause the processor to perform operations 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;
• cause transmission of the MAC resource assessment trigger frame to the first STA and the first group of STAs, the MAC resource assessment trigger frame to trigger a transmission of a second trigger frame by the first STA, the second trigger frame to allocate a portion of the first TxOP to the first group of STAs to respond to the MAC resource assessment trigger frame;
• and
• 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 first data transfer during a first data transfer stage, an interframe space after the first TxOP.

An apparatus comprising:

• a memory;
• and
• circuitry coupled with the memory to:
• receive a medium access control (MAC) resource assessment trigger frame from a channel enabler, the MAC resource assessment trigger frame to allocate a portion of a first transmission opportunity (TxOP) to the apparatus and to request a first resource assessment from a first group of stations (STAs) for evaluation by the apparatus, the first resource assessment to assess peer-to-peer (P2P) data transfers between the first group of STAs and the apparatus;
• cause transmission of a second trigger frame in response to receipt of the MAC resource assessment trigger frame, the second trigger frame to allocate a portion of the first TxOP to the first group of STAs to respond to the MAC resource assessment trigger frame;
• 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 first data transfer during a first data transfer stage, an interframe space after the first TxOP;
• and
• evaluate the one or more short term resource assessment frames from the first group of STAs to determine time resources to allocate to the first group of STAs during the first data transfer stage.
