Abstract: A method is provided for receiving a signal by a user equipment (UE) using time division duplex (TDD) in a wireless communication system. The UE receives uplink (UL) grant information on a first cell, the UL grant information scheduling a UL transmission on a second cell. The UE transmits UL data in a UL subframe on the second cell via a physical UL shared channel based on the UL grant information. The UE receives hybrid automatic repeat and request acknowledgement (HARQ-ACK) information in a downlink (DL) subframe on the first cell. The first cell and the second cell have different TDD UL-DL configurations. The DL subframe on the first cell is determined based on a TDD UL-DL configuration of the second cell.

Abstract: A method and apparatus are presented for transmitting a signal in accordance with an adaptive blind interference alignment (BIA) scheme in a wireless access system. A transmitter configures a first block including desired signals and interference signals on the basis of a number of receivers within a cell and a number of reception modes of the receivers. Further, the transmitter configures a second block including either the desired signals or the interference signals, and configures alignment blocks for each of the receivers by combining the first block with the second block. The transmitter transmits the alignment blocks to the receivers in accordance with transmission symbol patterns corresponding to the alignment blocks. Symbol vectors included in the alignment blocks for each of the receivers are configured to be overlapped between the receivers.
