Abstract: The present invention discloses an apparatus, a method and a computer program for resolving a hidden node problem in relation to handshake message transferring e.g. in WLAN networks. In one embodiment of the invention, the apparatus receiving a Clear to Send (CTS) message repeats the message after a Short Interframe Space (SIFS) time period. Stations not directly hearing the original CTS due to a low power are able to receive the repeated CTS and defer their transmissions accordingly. In another embodiment, the apparatus receiving the CTS message indicates in its Ready to Send (RTS) message that the CTS sender station has a low transmitting power. With this knowledge, the other present stations can defer their transmissions until they are sure that the data transfer between the first two stations having the RTS-CTS messaging has not been initiated or is already completed.

Abstract: The invention allows fairness provision in wireless mesh networks with respect to the data rate that stations communicate. A fairness metric is obtained during a mesh profile negotiation performed in order for a wireless station to join a wireless mesh network. Predetermined mesh transmission parameters of the wireless station are sent to previously joined wireless stations in a predetermined neighborhood of the wireless station. From the previously joined wireless stations their respective predetermined mesh transmission parameters are received. In response to a first predetermined event, a transmission opportunity window is determined for the wireless station based on the obtained fairness metric, the predetermined mesh transmission parameters of the wireless station, and the predetermined mesh transmission parameters of the previously joined wireless stations.
