Problems solved by technology

Due to the lack of a proper and robust judging mechanism in the related art, erroneous operations caused by wrong judgments may occur, for example, the transmitting power (transmitting power, TX power) of the second wireless packet may be too high or too low, making the first wireless packet Packets that are jammed or transmitted go undetected, which can cause redundant and unnecessary retransmissions, wasting bandwidth
As a result, the overall performance of conventional wireless communication systems is reduced

Abstract

The present invention provides a method and an apparatus for spatial reuse enhancement in a multi-station environment. The method comprises the following steps: if the wireless communication device receives a receiving packet, checking a space reuse limit to carry out a first-stage space reuse judgment; if the space reuse limit meets the preset condition, triggering a transmission module to starta second-stage space reuse judgment; scanning at least one contention queue to obtain an index of the candidate station from the at least one contention queue; obtaining latest information of the candidate station from an internal database of the wireless communication device based on the index so as to calculate a threshold value special for the candidate station according to the latest information; and comparing an intensity indicator corresponding to the received packet with the threshold to generate a comparison result, so as to control triggering of a spatial reuse contention channel according to the comparison result.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a method and an apparatus (apparatus) for enhancing spatial reuse (SR) in a multi-station (STA) environment. Background technique [0002] According to the related art, one or more devices in a conventional wireless communication system may perform spatial reuse, which may cause certain problems. For example, when a first device is transmitting a first wireless packet, a second device may attempt to spatially reuse the channel resource being used by the first wireless packet, especially, by transmitting a second A wireless packet, such as a packet that occurs simultaneously with the first wireless packet and overlaps with a channel or sub-channel being used by the first wireless packet. Due to the lack of a proper and robust judging mechanism in the related art, erroneous operations caused by wrong judgments may occur, for example, the transmitting power (transmitting p...
