  • Publication number: 20240163939
    Abstract: Techniques for improved peer-to-peer grouping in multi-link operations are provided. An indication of radio frequency (RF) capabilities of a peer-to-peer device is transmitted, and the peer-to-peer device receives a group ID assigned by a wireless access point (AP) based on the RF capabilities, where the group ID is associated with a set of links that can be used for peer-to-peer communications between peer-to-peer devices in a first group of peer-to-peer devices. The peer-to-peer device can request that the AP schedule a transmission opportunity for a first peer-to-peer communication using the group ID. In response to receiving a trigger frame comprising the group ID, the first peer-to-peer device performs the first peer-to-peer communication using the transmission opportunity.

  • Publication number: 20240163866
    Abstract: Techniques for improved peer-to-peer communication are provided. A wireless access point (AP) may initiate peer-to-peer communication between multilink peer-to-peer devices by sending a trigger frame addressed to the peer-to-peer devices to hand over a transmission opportunity (TXOP). The trigger frame is sent based on the AP's knowledge of the availability of the peer-to-peer devices for peer-to-peer communication. The trigger frame indicates a link to be used for the peer-to-peer communication. In response to receiving the trigger frame one or more of the peer-to-peer devices acknowledge the trigger frame, tune to the assigned link, and use the remaining portion of the TXOP for peer-to-peer communication.

  • Publication number: 20240163703
    Abstract: Embodiments herein describe assigning RUs to P2P stations to perform P2P communication. An AP can assign trigger frames to assign RUs to STAs to use when transmitting data to the AP. In one embodiment, the AP polls the P2P STAs associated with it to receive interference data. This data can indicate the affect other peer STAs have on the P2P STAs when transmitting data. Using the interference data, the AP can determine whether another P2P pair or a non-P2P station can be assigned RUs to transmit at the same time, and at what data rates.
