Patent ID: 8135337

Claim:
A method for relaying information in a wireless relaying network having a number of network nodes, said network comprising a designated originating node, at least one relaying node, and at least two receiving nodes, wherein said method comprises the steps of: said designated originating node transmitting a pilot signal; said at least one relaying node receiving and forwarding said pilot signal; each of said receiving nodes receiving said pilot signal and measuring channel quality based on the received pilot signal; at least part of said receiving nodes feeding back information on the measured channel quality all the way to said designated originating node; said designated originating node scheduling data for transmission by selecting at least one of said receiving nodes based on received channel quality information and selecting data associated with the selected receiving node(s) for transmission; said designated originating node transmitting a signal comprising said selected data and a cyclic prefix to the selected receiving node(s) via the same at least one relaying node that forwarded the pilot signal, wherein said network is based on OFDM (Orthogonal Frequency Division Multiplexing) or OFDMA (Orthogonal Frequency Division Multiple Access), and wherein said cyclic prefix is adapted to a power delay profile of an equivalent channel between the designated originating node and the selected receiving node(s) via the at least one relaying node, said at least one relaying node receiving the signal transmitted by said originating node, and with a latency substantially smaller than the OFDM symbol duration, transmitting the signal in the same frequency band, wherein the signal transmitted by the relaying node constructively interferes with the signal transmitted by the designated originating node when received by the selected receiving node(s).
