1. A method for transmitting and receiving a frame in a wireless local area network (WLAN) system, the method comprising:
transmitting, by an access point (AP), a first frame to a first station (STA) through a first band; and
receiving, by the AP, a second frame from a second STA through a second band while transmitting the first frame,
wherein 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.
