Device and method for spatial reuse in wireless network environment

Abstract

Provided are a device and method for spatial reuse in a wireless network. According to the device and method for spatial reuse, concurrent transmission power is calculated that is a power for transmitting a signal concurrently with an occupant transmission node, which is occupying a channel and transmitting a signal with reference transmission power, on the basis of a density of nearby access points (APs), a clear channel assessment (CCA) threshold is adjusted and set in accordance with the concurrent transmission power, and whether to perform concurrent transmission is determined in accordance with the CCA threshold and an intensity of the signal transmitted by the occupant transmission node. Accordingly, it is possible to efficiently reuse space.

Dependencies are inferred from the claim text.
