Abstract
The invention concerns a method for measuring channel state information of multiple transmission/reception modes in a wireless network comprising a plurality of nodes, said modes being defined by frequency channels and/or antenna patterns, said wireless network comprising a MAC (Media Access Control) layer and every node comprising at least one MAC queue, comprising the steps of:periodically sending broadcast probe packets by at least one node called transmitter node, using a pre-determined and globally known period and predetermined sequence of transmission modes, each of said probe packets containing the transmission mode used for its transmission a sequence number of the transmission mode in the pre-determined sequence of transmission modes and a timestamp value containing the time said broadcast probe packet was buffered at the MAC queue of the transmitter node; measuring, by at least one second node called receiving node receiving a broadcast probe packet , channel state information of a transmission/reception mode for the link between the transmitter node and the receiving node; storing, by said receiving node, said measured transmission/reception mode for said link; using in…
