Abstract

A method for allocating resources of physical hybrid ARQ indicator channels is disclosed, comprising: a transmitting end dividing evenly all resources of Physical Hybrid ARQ Indicator Channels (PHICHs) to be allocated into a plurality of configured PHICH groups, and then mapping them to sub-carriers of resource groups corresponding to the PHICH groups to transmit signals in the PHICHs through the sub-carriers. The present invention enables Hybrid Automatic Repeat reQuest function to be implemented in a practical system, and also ensures minimum interference between different users and improves the utilization of system resources.
