Abstract: A method and apparatus for transmitting or receiving channel quality control information through a physical uplink shared channel (PUSCH) in a wireless access system that supports hybrid automatic retransmit request (HARQ). In one embodiment, a user equipment (UE) receives a physical downlink control channel (PDCCH) signal including an initial uplink grant, transmits uplink data using two transport blocks based on the initial uplink grant, receives a negative acknowledgement (NACK) information for one of the two transport blocks, and transmits a channel quality control information along with the one of the two transport blocks which is retransmitted according to the NACK information or a new transport block through the PUSCH to which the HARQ is applied. A number of coded symbols required to transmit the channel quality control information (Q′) is calculated based on the initial uplink grant.

Abstract: A reference signal transmission scheme is presented. A first user equipment (UE) receives first information identifying which uplink subframe of a plurality of subframes is enabled to transmit an uplink reference signal, and receives second information identifying a sequence used for the uplink reference signal from a base station. The first information is used to identify a different uplink subframe to a first UE group including the first UE and a second UE group other than the first UE group. The second information is determined to assign different orthogonal sequences to each of UEs of the first UE group. The first UE transmits the uplink reference signal to the base station at the uplink subframe identified by the first information using the sequence identified by the second information.

Abstract: A method is presented for transmitting signals at a User Equipment (UE) in a multi-antenna wireless communication system. Acknowledgment (ACK)/negative ACK (NACK) information is received from a base station (BS). At least one transport block negatively acknowledged by the ACK/NACK information is retransmitted to the BS. An uplink grant for retransmitting the at least one transport block is not detected. If a number of the at least one transport block is not equal to a number of transport blocks indicated by a most recent uplink grant, cyclic shift values and orthogonal cover codes (OCCs) of a demodulation reference signal (DMRS) for the at least one transport block are configured based on a cyclic shift field included in the most recent uplink grant and a number of layers corresponding to the at least one transport block.

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.
