摘要： A method and wireless station for receiving signals. The wireless station receives, from a base station, a control signal on a first subframe indicated as a downlink (DL) subframe by a time division duplex (TDD) uplink-downlink (UL-DL) subframe configuration. The control signal includes first information indicating that at least one UL subframe indicated by the TDD UL-DL subframe configuration is reconfigured as a TDD DL subframe. The wireless station receives, from the base station, DL data on a second subframe which was indicated as a TDD UL subframe by the TDD UL-DL subframe configuration but is currently reconfigured as a TDD DL subframe by the control signal. The wireless station transmits, to the base station, UL data on a TDD UL subframe except for being reconfigured as the TDD DL subframe by the control signal.

摘要： A method of decoding a backhaul downlink signal of a relay node (RN). A higher layer signal indicating a maximum transmission rank is received from a base station (BS). Control information is received through a relay control channel from the BS. The control information is demodulated and mapped to resource elements (REs) which do not overlap with user equipment-specific reference signal (URS) REs in a control region which is used for the relay control channel transmission of the BS. The URS REs are reserved REs for URSs according to the maximum transmission rank. The control information is demodulated based on URSs transmitted by the BS on one fixed antenna port n, where n is a natural number.
