Abstract

Embodiments herein relate to a first station (STA1) and a method performed by a first station (STA1) for handling Request-to-Send/Clear-to-Send, RTS/CTS, transmissions in a wireless communications network (100). The first station (STA1) is served by a first access point (AP1) in a first Basic Service Set (BSS1). The first station (STA1) receives a RTS/CTS transmission relating to a second Basic Service Set (BSS2). Then, the first station (STA1) determine whether or not to set a Network Allocation Vector, NAV, according to the RTS/CTS transmission based on whether the RTS/CTS transmission was sent from a second station (STA2) or from a second access point (AP2) in the second Basic Service Set (BSS2).Embodiments herein also relate to a first access point (AP1) and a method performed by a first access point (AP1) for handling RTS/CTS transmissions in a wireless communications network (100).
