  • TRANSMITTING RADIO EQUIPMENT, RECEIVING RADIO EQUIPMENT AND CORRESPONDING METHODS FOR COMMUNICATING USING A REFERENCE SIGNAL
    Publication number: 20190280909
    Abstract: Methods and transmitting and receiving radio equipments for transmitting and receiving a reference signal in a subframe where a portion of one or more multi-carrier modulation symbols that is included in the subframe is used for transmitting control information to receiving radio equipments. The transmitting radio equipment transmits the reference signal overlaid on at least a part of the portion of the one or more multi-carrier modulation symbols that is used for transmitting the control information in the subframe. The reference signal is generated based on at least one parameter. The receiving radio equipment then receives a transmission including the control information and the reference signal in the subframe, and may determine one or more properties of the reference signal based on the at least one parameter and process the reference signal using the determined one or more properties of the reference signal.

  • Sidelink communication techniques in radiocommunication systems
    Patent number: 10390342
    Abstract: A method for sidelink communication between a first wireless node and a second wireless node is described, the sidelink communication using sub-frames of a first type and a second type. The first wireless node determines whether the first wireless node is an initiator or responder of the sidelink communication. If the first wireless node determines that the first wireless node is an initiator of the sidelink communication, then it transmits data directly toward the second wireless node using the first sub-frame type. Alternatively, if the first wireless node determines that the first wireless node is a responder of the sidelink communication, then it transmits data directly toward the second wireless node using the second sub-frame type, the first sub-frame type being different than the second sub-frame.

  • Variable transport format parameters for fast acknowledgment feedback mechanism
    Patent number: 10237019
    Abstract: A first communication node (110) receives a stream of code blocks from a second communication node (120) over an acknowledged connection (131.). The first communication node processes the received code blocks in accordance with at least one transport format parameter, TFP, detects errors in received code blocks, and transmits an acknowledgment in respect of groups of code blocks indicating whether at least one error was detected in the group. A first subset of the code blocks of a group are transmitted (e.g., modulated and demodulated) in accordance with a first TFP value, and a remainder of the code blocks are transmitted in accordance with a second TFP value. Because the first and second TFP values are independent, it is possible either to shorten the necessary processing time in the first communication node or, in connection with a predictive acknowledgment mechanism, to make the receiving-side processing of code blocks that do not contribute to the value of the transmitted acknowledgment more robust.

  • Transmitting partitioned radio signals using multiple radio chains
    Patent number: 10225742
    Abstract: A method performed by a radio network node for determining a partitioning of a first signal into one or more parts to be transmitted to a first radio node. The radio network node comprises two or more antennas, each associated with a respective radio chain. The radio network node and the radio node operate in a wireless communications network. The radio network node determines a number of radio chains, to be used to send the first signal, and determines a partitioning of the first signal into the one or more parts of the first signal over the determined number of radio chains. The one or more parts are to be transmitted to the first radio node. The radio network node determines the number of radio chains and the partitioning based on a scheduling decision associated with the radio network node, and one or more parameters.

  • ECOLOGICAL SEQUESTRATION OF CARBON DIOXIDE/INCREASE OF BIO-ENERGY OBTAINABLE THROUGH BIOMASS
    Publication number: 20180258847
    Abstract: According to known methods, biomass is broken down under the action of water vapour via a carbon monoxide-hydrogen mixture (called synthesis gas) as an intermediate stage into hydrogen and carbon dioxide instead of being combusted directly to generate energy. Carbon dioxide is stored/sequestered and the hydrogen is used to generate energy. The transfer of bio-activity can also be effected within the same process by breaking down a mixture of biomass and fossil fuel (e.g. wood and coal) into carbon dioxide and hydrogen. The hydrogen is then reacted with half of the formed carbon dioxide to form methane and the remaining carbon dioxide is stored. The stored carbon dioxide and generated methane respectively comprise one half each of biological and fossil carbon. If the bio-activity of the stored biocarbon dioxide is transferred to the fossil carbon in methane, a corresponding mixture of wood and coal produces 100% biomethane. Here, too, up to 100% biomethane can be obtained from coal-wood mixtures.
