    摘要: The disclosure provides a method and a device for feeding back Acknowledgment (ACK) information during switching of backhaul link subframe configuration, and the method includes during the switching of the backhaul link subframe configuration, if Uplink (UL) ACK/Negative ACK (NACK) information, which corresponds to a last transmission before the switching of one or more Downlink (DL) Hybrid Automatic Repeat Request (HARQ) transmissions, is not fed back on a UL subframe which is before the switching, feeding back the ACK/NACK information on an available UL subframe which is after the switching since Nms after the last transmission, wherein N is an integer. The disclosure achieves the effect of correctly feeding back the ACK information during switching of the backhaul link subframe configuration.

    摘要: The present invention discloses a transmission method and system for a Relay Physical Downlink Control Channel (R-PDCCH). The method comprises the steps of: an eNB bearing downlink grant information of a relay node onto an available Orthogonal Frequency Division Multiplex (OFDM) symbol of a first slot of a pre-allocated Physical Resource Block (PRB) pair used for bearing the R-PDCCH, wherein available OFDM symbols in the PRB pair, other than the OFDM symbol used for the downlink grant information, are used for bearing a Physical Downlink Shared Channel (PDSCH) of each relay node; the eNB transmitting the PRB pair bearing the downlink grant information and the PDSCH to the relay node. The present invention is well applicable to a link between an eNB and a relay node, and meanwhile enables backhaul resources to be used adequately.

    摘要: A method and an apparatus for determining a relay link resource element group are disclosed. The method includes: determining a size of a relay link resource element group according to a pattern of a non-zero-power Channel State Information Reference Signal (CSI-RS), and/or a pattern of a zero-power CSI-RS and/or a pattern of a Common Reference Signal (CRS), and/or a pattern of a Demodulation Reference Signal (DMRS) transmitted in a resource block in which the resource element group locates in allocated resources. The allocated resources are used for a transmission over a relay link physical downlink control channel, including one or more continuously or discretely distributed resource blocks in the frequency domain, while including one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols in the time domain.

    摘要: The disclosure discloses a method, system and RN for processing UCI on a backhaul link. The method comprises that: the RN determines Q′ which is the number of the coded modulation symbols of the backhaul UCI according to the number of SC-FDMA symbols occupied by a GP, wherein the GP comprises RN state switch time deltaT and/or the time interval deltat which is reserved for avoiding the interference caused by RN uplink transmission, and deltaT is the switch time required by the RN to switch from an uplink reception state to an uplink transmission state and/or from the uplink transmission state to the uplink reception state; and the RN codes the backhaul UCI into a Q=Q′×Qm bits sequence, wherein Qm is the number of bits comprised in each coded modulation symbol in the modulation order of the backhaul uplink subframe. The disclosure improves the performance of the system.
