摘要： There is provided a method of controlling access to a shared wireless medium in a wireless communication system operating based on a contention-based protocol for medium access. The method is based on deciding, for a first communication unit intending to use the shared wireless medium for a transmission to a second communication unit, and based on a representation of robustness of a transmission on the shared wireless medium between a third communication unit and a fourth communication unit, whether concurrent use of the shared wireless medium by the first communication unit is allowed.

摘要： A first Wireless Local Area Network (WLAN) node and a method therein for performing a transmission to a second WLAN node in a WLAN. The first WLAN node identifies a third WLAN node transmitting a first signal (S1) overheard by the first WLAN node, and determines to transmit, to the second WLAN node, a second signal (S2) based on the identity of the third WLAN node and on a received power of the first signal. When determined to transmit the second signal, the first WLAN node determines a Modulation and Coding Scheme (MCS) index value by means of a link adaptation process specific for the identified third WLAN node and transmits to the second WLAN node, the second signal using the determined MCS index.

摘要： 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.

摘要： There is provided a method of controlling access to a shared wireless medium in a first wireless communication system based on a contention-based protocol for medium access involving carrier sensing, wherein the first wireless communication system is of a first radio access technology. The method comprises determining (S1) whether a second wireless communication system of a second, different radio access technology is operating on the same channel of the shared wireless medium as the first wireless communication system. The method also comprises initiating (S2), if the second wireless communication system is operating on the same channel, a change of a carrier-sensing threshold used in the first wireless communication system for determining, for at least one communication unit, whether the medium is available for access from a first level to a second, different level.
