Claim of US Patent No. 10,142,993

1. A method implemented by a receiving station in a Wireless Local Area Network (WLAN) to initiate a change in a receive operating mode during a current transmission opportunity (TXOP) of a transmitting station, the method comprising:sending, by the receiving station, a receive operating mode change to the transmitting station, wherein the receive operating mode change requests changes to at least one receive operating mode parameter associated with at least one transmission from the transmitting station to the receiving station;
determining whether the receive operating mode change requests a change of the at least one receive operating mode parameter (1) from higher receiver resource usage, which is used during the current TXOP, to lower receiver resource usage or (2) from lower receiver resource usage, which is used during the current TXOP, to higher receiver resource usage;
changing, by the receiving station in response to determining that the receive operating mode change requests a change of the at least one receive operating mode parameter from lower receiver resource usage to higher receiver resource usage, the at least one receive operating mode parameter from lower receiver resource usage to higher receiver resource usage after receiving an acknowledgment from the transmitting station of the receive operating mode change; and
changing, by the receiving station in response to determining that the receive operating mode change requests a change of the at least one receive operating mode parameter from higher receiver resource usage to lower receiver resource usage, the at least one receive operating mode parameter from higher receiver resource usage to lower receiver resource usage, wherein changing the at least one receive operating mode parameter occurs only after completion of the current TXOP when the at least one receive operating mode parameter changes from higher receiver resource usage to lower receiver resource usage.
