A method of transmitting uplink signals is disclosed. The method includes transmitting, by a user equipment, periodic control information on a Physical Uplink Control Channel (PUCCH) at a predetermined period, dropping the periodic control information and multiplexing uplink signals except the periodic control information when the user equipment is operating in subframe bundling transmission mode where the uplink signals are transmitted in a plurality of consecutive subframes, and transmitting the multiplexed uplink signals on a Physical Uplink Shared Channel (PUSCH).

A method for mapping a physical hybrid automatic repeat request indicator channel (PHICH) is described. The method for mapping a PHICH includes determining an index of a resource element group transmitting a repetitive pattern of the PHICH, according to a ratio of the number of available resource element groups in a symbol in which the PHICH is transmitted and the number of available resource element groups in a first or second OFDM symbol, and mapping the PHICH to the symbol according to the determined index. In transmitting the PHICH, since efficient mapping is performed considering available resource elements varying with OFDM symbols, repetition of the PHICH does not generate interference between neighbor cell IDs and performance is improved.
