Claim of US Patent No. 10,602,546

1. A method used in a wireless Local Area Network (LAN), comprising:receiving, by a first station (STA) from an access point (AP), a single request to send (RTS) frame triggering transmission of multiple clear to send (CTS) frames from multiple STAs on an overlapping frequency band including a 20 MHz band during a same time period;
in response to the single RTS frame, transmitting, by the first STA to the AP, a first CTS frame on the overlapping frequency band during the same time period; and
receiving, by the first STA from the AP, a downlink physical layer protocol data unit (PPDU) based on the overlapping frequency band.
