Samsung patents Wi-Fi method for sharing airtime between devices
Samsung has filed a patent for a way to manage Wi-Fi traffic in peer-to-peer groups. The system uses specific signal frames to tell devices when they are allowed to transmit data, reducing interference between multiple users.
In the filing’s own words
Methods and apparatuses for transmission opportunity (TXOP) sharing for peer to peer (P2P) group (TXSPG) operation. A method performed by a non-access point (AP) station (STA) includes receiving, from an AP, a multi-user (MU)-request to send (RTS) TXOP sharing (TXS) trigger frame; determining whether the MU-RTS TXS trigger frame includes a common info field with a TXS mode field equal a value and a user info field including an identifier associated with a P2P group of the non-AP STA; and transmitting, based on determining that the MU-RTS TXS trigger frame includes the common info field with the TXS mode field equal the value and the user info field including the identifier associated with the P2P group of the non-AP STA, a clear to send (CTS) frame a short interframe space (SIFS) time after an end of a physical layer protocol data unit (PPDU) carrying the MU-RTS TXS trigger frame.
What exactly they claim (claim 1)
1. A method performed by a non-access point (AP) station (STA), the method comprising: receiving, from an AP, a multi-user (MU)-request to send (RTS) transmission opportunity (TXOP) sharing (TXS) trigger frame; determining whether the MU-RTS TXS trigger frame includes (i) a common info field with a TXS mode field equal a value and (ii) a user info field including an identifier associated with a peer to peer (P2P) group of the non-AP STA; and transmitting, based on determining that the MU-RTS TXS trigger frame includes (i) the common info field with the TXS mode field equal the value and (ii) the user info field including the identifier associated with the P2P group of the non-AP STA, a clear to send (CTS) frame a short interframe space (SIFS) time after an end of a physical layer protocol data unit (PPDU) carrying the MU-RTS TXS trigger frame.
