Abstract
Embodiments of the present invention disclose a method and a device for allocating a physical hybrid ARQ indicator channel, and a user equipment. The method for allocating a physical hybrid ARQ indicator channel includes: determining, according to an extended parameter, a cyclic shift value of a demodulation reference signal that is indicated in a Physical Downlink Control Channel PDCCH, and a minimum labeling index value of a physical resource block PRB that is occupied by an uplink data transmission block, a PHICH index number that corresponds to the uplink data transmission block, where the extended parameter includes a cell-specific parameter and a user-equipment-specific parameter; and allocating a PHICH to the uplink data transmission block according to the PHICH index number.
