Claim of US Patent No. 10,462,799

1. A method performed by a first node for controlling transmission of a first signal, wherein the first node is operating in a Basic Service Set, BSS, comprised in a Wireless Local Area Network, WLAN, and wherein the method comprises:detecting a second signal transmitted from a second node operating in the WLAN;
determining a node type of the second node;
comparing a signal strength of the second signal with a threshold value for the second node, wherein the threshold value for the second node is determined based on the node type of the second node, wherein each threshold value for each one of a plurality of node types including the node type of the second node comprises a different threshold value than each other node type of the plurality of node types;
transmitting the first signal when the signal strength of the second signal is below the threshold value; and
deferring from transmitting the first signal when the signal strength of the second signal is above the threshold value, whereby the transmission of the first signal is controlled.
