摘要： A method of conducting full-duplex transmission between first and second nodes in a communications system having more than two nodes includes the issuing of a start signal on a channel by the first node, wherein the start signal signals that full-duplex transmission is to begin, and identifies the second node as a node with which full-duplex communication is to occur. The method also includes, following the issuing of the start signal, the beginning of full-duplex transmission by the first and second nodes. A node, for use in a network including at least two nodes, is configured to initiate full-duplex communication with any other node by issuing a start signal, where the start signal signals that full-duplex transmission is to begin, and identifies a second node as a node with which full-duplex communication is to occur, and by, following the issuing of the start signal, beginning full-duplex communication.

摘要： Methods and apparatus for performing full-duplex communications using a G.hn protocol are provided. A second node of a plurality of nodes is selected, by a first node with which to engage in full-duplex communications. A first seed common to the plurality of nodes is retrieved. A search is performed for a second seed assigned to the second node. A first portion of a frame is generated for transmission using a half-duplex communications mode, wherein transmissions using the half-duplex communications mode are detectable by each of the nodes. A first group of subcarriers is loaded with the first set of phases generated using the first seed and a second group of subcarriers is loaded with the second set of phases generated using the second seed. The first portion is transmitted, in the half-duplex communications mode, from the first node using the first and second groups of subcarriers.
