LOW LATENCY SCHEMES FOR PEER-TO-PEER (P2P) COMMUNICATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17482417 titled 'LOW LATENCY SCHEMES FOR PEER-TO-PEER (P2P) COMMUNICATIONS

Simplified Explanation

This patent application is about managing data traffic in restricted target wake time (TWT) service periods (SPs) in wireless communication systems. Here are the key points:

  • The patent application describes a system for managing data traffic in restricted TWT service periods.
  • The system includes an access point (AP) and a wireless station (STA) associated with a client device.
  • The STA sends a request frame to the AP indicating its intention to exchange peer-to-peer (P2P) communications with the client device during a scheduled r-TWT SP.
  • The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP and transmits a trigger frame to allocate a portion of the TXOP for P2P communications between the STA and the client device.
  • The trigger frame or the response frame indicates a Network Allocation Vector (NAV) exception for the client device.

Potential applications of this technology:

  • Wireless communication systems that require efficient management of data traffic during restricted TWT service periods.
  • Peer-to-peer communication scenarios where a client device needs to communicate with a wireless station during scheduled wake time periods.

Problems solved by this technology:

  • Efficient management of data traffic during restricted TWT service periods.
  • Ensuring that the client device and the wireless station can communicate effectively during the scheduled wake time periods.

Benefits of this technology:

  • Improved efficiency in managing data traffic during restricted TWT service periods.
  • Enhanced communication capabilities between client devices and wireless stations during scheduled wake time periods.


Original Abstract Submitted

This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-to-peer (P2P) link, the request frame indicating that the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.
