  • Patent number: 8953476
    Abstract: A method for scheduling a first user equipment, UE, with a first performance causing a first self interference of a relay system between a first access link extending between the relay system and the first UE and a relay link extending between the relay system and a base station, BS, and scheduling a second UE with a second performance causing a second self interference of the relay system between a second access link extending between the relay system and the second UE and the relay link extending between the relay system and the BS. Thereby, if the first self interference is larger than the second self interference, the first performance is smaller than the second performance. Alternatively, if the first self interference is smaller than the second self interference, the first performance is larger than the second performance.

  • Patent number: 8935588
    Abstract: A decoding method for decoding information content in at least one data packet, which is transmitted from a sender to a receiver via a data link. The information is represented by a bit sequence, which is transformed into a transmittable redundancy version. The information is initially transmitted for a first time in a first data packet from the sender to the receiver. The information is represented by a first redundancy version, which is self-decodable. An incorrect receipt is confirmed by sending a confirmation from the receiver to the sender. The information is retransmitted at least a second time in a second data packet from the sender to the receiver upon receipt of the confirmation, wherein, for representation of the information, a second redundancy version is used, the selection of which is performed in dependence on a coding parameter, describing whether the redundancy version is self-decodable or not.

  • Publication number: 20150009964
    Abstract: Embodiments of an enhanced node B (eNB) and methods for network-assisted interference cancellation with reduced signaling in a 3GPP LTE network are generally described herein. In some embodiments, the number of transmission options is reduced by introducing a smaller signaling codebook. In some embodiments, higher-layer feedback from the UE to the eNodeB is established to inform the eNB about certain NA-ICS capabilities of the UE. In some embodiments, the number of signaling options is reduced by providing only certain a priori information. In some embodiments, correlations in the time and/or frequency domain are exploited for reducing the signaling message. In some embodiments, differential information is signaled in the time and/or frequency domain for reducing the signaling message.

  • Publication number: 20150009948
    Abstract: Embodiments for providing demodulation reference signals to provide side information for interference cancellation are generally described herein. In some embodiments, a sub-frame is prepared comprising two slots and configuring a physical resource block (PRB) for each slot, wherein each PRB comprises twelve Orthogonal Frequency Division Multiplexing (OFDM) subcarriers transmitting for a duration of 7 OFDM symbols per slot. In resource elements on each of three of twelve OFDM subcarriers, two pairs of demodulation reference signals (DMRS) are allocated to form three DMRS sets. Symbols are mapped with a first modulation for the two pairs of demodulation reference signals to three of the twelve OFDM subcarriers for transmission. A second modulation is added to a first of the three DMRS sets and a third modulation is added to a second of the three DMRS sets to indicate side information regarding an interfering signal for use in mitigating the interfering signal.

  • Patent number: 8842652
    Abstract: A relay node receives from user equipments UE CQI reports which give a CQI value per radio band resource RBR, from which are aggregated across the RBRs and/or aggregated per UE across that UE's RBR values. The relay node reports an indication of the average to its controlling access node (eNodeB), either explicitly or implicitly (e.g., a gain applied to the CQI of the downlink between the relay and access nodes). The relay node also checks the UEs' buffer status (actual or predicted) and reports either periodically or based on an underflow/overflow occurrence. For periodic reports, each UE buffer experiencing the overrun/underrun is reported.
