Problems solved by technology

[0018] In practice, increasing the CCA threshold will exacerbate the hidden node problem, since other stations will not be detected by the stations' receivers, but their signal-to-noise-to-interference ratio (SINR) will be affected by the transmissions of said stations

Abstract

A station and a method for operating the station are described. The station comprises a receiver configured to receive a wireless signal sent via a wireless channel, a clear channel assessment, CCA, detector configured to detect, based on a CCA threshold, if the wireless channel is busy and a controller configured to adjust the CCA threshold of the CCA detector when the wireless channel is busy and the signal received via the wireless channel is not meant for the station.

Description

technical field [0001] The invention relates to the field of wireless data transmission, in particular to a station and a method for operating the station. technical background [0002] In an IEEE 802.11 network, a station uses a Clear Channel Assessment (CCA) mechanism to determine whether the channel is busy during carrier sense multiple access / collision avoidance (CSMA / CA) and backoff. If the channel is considered busy, the station will stop transmitting any data until the channel is free for a predefined period of time. [0003] The IEEE 802.11 standard supports three basic topologies and two methods of operation. The three basic topologies are: first, Independent Basic Service Set (IBSS)—also known as an ad-hoc network. The IBSS consists of several stations communicating directly with each other on an ad-hoc network and on a peer-to-peer basis. Thus, it includes a set of stations that communicate with each other without an Access Point (AP) or any connection to a wir...
