Abstract: A method and system for a sharing access point (AP) to allocate one or more service periods of a transmit opportunity (TXOP) time to one or more shared AP. In an example, the sharing AP transmits one or more multi-user request to send TXOP sharing (MU-RTS TXS) frames to the one or more shared AP to indicate the allocation to the one or more shared AP and receives a respective clear to send (CTS) from the one or more shared AP in response to a corresponding MU-RTS TXS frame to indicate a confirmation by a respective shared AP which will use the allocated service period of the TXOP. The shared AP then performs one or more of a downlink transmission and uplink reception in the allocated service period.
