    摘要： A method is provided for an access node to perform channel estimation. The method includes, when a UE and a relay node are present in a cell with the access node, the access node receiving from the UE and from the relay node DMRS that are cyclically shifted relative to one another. The method further includes the access node performing a first channel estimation based on the DMRS that was transmitted by the UE, performing a second channel estimation based on the DMRS that was transmitted by the at least one relay node, combining the first channel estimation with the second channel estimation to derive a combined channel estimation, using the first channel estimation to demodulate control information received from the UE, and using the combined channel estimation to demodulate data received from both the UE and the at least one relay node.

    摘要： A method and system for formulating an SINR metric for cells using only the existing RSRP and RSRQ measurements. With this method and system side information is exchanged between eNBs of an E-UTRAN using the X2 interface where the X2 interface carries the X2 Application Protocol (X2AP). The side information is introduced either within X2AP messages exchanged between eNB nodes or via modification of existing X2AP messages. Serving cell system information block (SIB) messages may also be modified or new SIB messages introduced to facilitate computation of an SNIR metric at a UE.

    摘要： Devices and methods are provided for managing hidden node interference. A communications session between a client node and an access node is affected by interference generated by a hidden relay node. The victim client node and the aggravator relay node are identified by the access node. The access node generates a set of scheduling instructions, which are then provided to the client node. The client node then uses the scheduling instructions to avoid further interference.

    摘要： In a system for allocating resources of a wireless communication system power levels of downlink (DL) communication channels and coupling losses of uplink (UL) communication channels are determined. When the power level of the DL communication channel between a base station and a UA is greater than the power levels of the DL communication channels between each of a plurality of RNs and the UA, and the coupling losses of the UL communication channel between at least one of the RNs and the UA are less than the coupling losses of the UL communication channel between the base station and the UA, a DL communication channel resource on the base station to the UA, and a UL communication channel resource on the at least one of the plurality of RNs to the UA are allocated.

    摘要： A method for transmitting data to a user agent. The method includes a relay node receiving information from an access node, the information containing the data that is to be transmitted to the user agent and control information that the access node will use to transmit the data to the user agent. The method further includes the relay node transmitting the data to the user agent at the time the access node transmits the data to the user agent, the relay node using the control information that the access node uses to transmit the data to the user agent.
