Avoidance mechanism technology for space reuse

摘要

Present disclosure is disclosed reduces the technology for the delay that business transmission is dispatched in Overlapping Basic Service Set (OBSS) environment by changing avoidance mechanism.In some instances, equipment (such as, stand (STA) or access point (AP)) can decode reception packet lead code at least a portion, with determine packet whether be by OBSS member transmission (such as STA or AP from different BSS).Back-off operation is typically due to decode and postpone.Aspect in the present disclosure provides a kind of by reducing the methods, devices and systems of the delay in the transmission of scheduling business recovering back-off operation before by network allocation vector (NAV) for the period expiration that OBSS packets retain.In other words, equipment can not observe the NAV of OBSS packets, but perform space reuse by sending another packet (or signal) on identical frequency channels during the NAV that OBSS is grouped.
