Abstract  Abstract

The present invention relates to a physical indication channel allocation method. The method for allocating a physical indication channel according to an embodiment of the present invention includes allocating a CDM group according to a spread rate and a cyclic prefix type, and assigning a physical hybrid ARQ indication channel (PHICH) to the allocated CDM group. . Here, the PHICH includes an acknowledgment (ACK / NACK) signal multiplexed by the CDM method. According to embodiments of the present invention, it is possible to efficiently allocate resources for PHICH transmission and maintain the transmission structure regardless of spreading rate.
