Abstract
A method and apparatus for performing spatial reuse (SR) enhancement in a multiple-station environment are provided. The method includes: in response to a wireless communications device receiving a receiving packet, checking SR limitation to perform first stage SR determination; in response to the SR limitation conforming to a predetermined condition, triggering a transmitting module to start performing second stage SR determination; scanning at least one contention queue within the transmitting module to obtain an index of a candidate station from the contention queue; obtaining latest information of the candidate station from an internal database of the wireless communications device based on the index, to calculate a threshold dedicated to the candidate station according to the latest information of the candidate station; and comparing a strength indicator corresponding to the receiving packet with the threshold to generate a comparison result, to control triggering of SR backoff according to the comparison result.
