摘要:
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. In the method and the device for allocating a physical hybrid ARQ indicator channel, and the user equipment according to the embodiments of the present invention, through the extended parameter and the cyclic shift value of the demodulation reference signal, an adjustment range is widened when a base station allocates a PHICH channel to the UE.
