    摘要: Disclosed herein is a wireless access system and, more particularly, methods and apparatuses for designing a 256 quadrature amplitude modulation (QAM) constellation point and transmitting a modulation symbol using the same in order to support a 256QAM scheme. The method for transmitting a modulation symbol using a 256 quadrature amplitude modulation (QAM) scheme at a transmitter in a wireless access system includes modulating octuplet bits into one modulation symbol using the 256QAM scheme, mapping the modulation symbol to one of 256QAM constellation points and transmitting the mapped modulation symbol.

    摘要: The present invention relates to a method for transmitting and receiving an uplink signal for low-cost machine-type communication (MTC) used in a wireless communication system, and the apparatuses for supporting same. The base station of the present invention sets a maximum number of RBs capable of being allocated to the MTC device to be smaller than the total number of RBs in a system band supported by the base station. The MTC device of the present invention transmits an uplink signal through a physical uplink shared channel (PUSCH) on the basis of the maximum number of RBs capable of being allocated to the MTC device.

    摘要: A method for transmitting uplink control information by a user equipment (UE) configured with a plurality of cells including a primary cell and a secondary cell in a wireless communication system is discussed. The method includes identifying, by the UE, a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK)(0) and a HARQ-ACK(1); and transmitting, by the UE, bits b(0)b(1) using a Physical Uplink Control Channel (PUCCH) resource among a plurality of PUCCH resources based on the HARQ-ACK(0) and the HARQ-ACK(1) to a base station (BS) for identifying the HARQ-ACK(0) and the HARQ-ACK(1). The b(0)b(1) and the PUCCH resource are given according to a relation including Table 1, where the HARQ-ACK(0) indicates an ACK/Negative ACK (ACK/NACK)/Discontinuous Transmission (DTX) response to a data block related to the primary cell, and the HARQ-ACK(1) indicates an ACK/NACK/DTX response to a data block related to the secondary cell.
