Abstract
A method is disclosed of an access point adapted to operate in association with a communication standard with application of a sense-before-transmit principle (a.k.a. a listen-before-talk principle, e.g. CSMA/CA) and adapted to communicate with one or more wireless communication devices associated with the access point. The method comprises (for each of the one or more wireless communication devices) maintaining (a respective clear channel assessment threshold value for the wireless communication device based on one or more parameters of the wireless communication device, wherein the respective clear channel assessment threshold value is for application in channel sensing related to an intended transmission to the wireless communication device. Corresponding computer program product, arrangement, physical layer convergence protocol (PLCP) sublayer, and wireless communication device are also disclosed.
