Claim 7:
8. An access point (AP) for transmitting and receiving a frame in a wireless local area network (WLAN) system, the AP comprising:
a memory;
a transceiver; and
a processor operatively coupled with the memory and the transceiver,
wherein the processor transmits a first frame to a first station (STA) through a first band and receives a second frame from a second STA through a second band while transmitting the first frame,
the first band and the second band are aggregated into a multi-band,
the multi-band simultaneously supports Downlink (DL) transmission and Uplink (UL) transmission,
the first STA and the second STA are in a hidden node relationship,
a Physical (PHY) header of the first frame comprises channel state information on the second band, and
a Network Allocation Vector (NAV) for the first STA is configured based on the channel state information.
