Abstract
The present disclosure provides a NAV (network allocation vector) setting method in a wireless communications system and a related device. The method includes: receiving, by a receiving node, a PPDU (physical layer protocol data unit) sent by a transmitting node; determining whether the receiving node satisfies a condition of allowing simultaneous transmission; and if the condition of allowing simultaneous transmission is satisfied, keeping a current NAV value unchanged; or if the condition of allowing simultaneous transmission is not satisfied, decoding the received PPDU to obtain a duration field, and updating the current NAV value of the receiving node according to a value of the duration field.
