Abstract:
1. A method for measuring channel state information of multiple communication modes in a multi-mode wireless network comprising a plurality of nodes, the method comprising: receiving a broadcast probe packet during a measurement period at a first node of said plurality of nodes from a second node of said plurality of nodes using a period and sequence of communication modes, wherein a communication mode is related to a transmission mode or a reception mode for a node of said plurality of nodes and is defined by at least a frequency channel and an antenna pattern, and wherein said broadcast probe packet comprises information including: measuring, by the first node, channel state information for communication mode used in connecting the second node and the first node; storing, by said first node, said measured channel state information for the communication mode used in connecting the first and second nodes; determining, by said first node, the communication mode for the first node using said information in said received broadcast probe packet; and determining a time during which said first node will use the determined communication mode in order to receive a subsequent broadcast probe packet from said second node during a next measurement period of said second node using said timestamp value from said received broadcast probe packet.
