Transmission Method, Device, and System for PHICH

摘要

Disclosed are a transmission method, device and system for physical hybrid ARQ indicator channel (PHICH). The method comprises the following steps: a NodeB scrambles the PHICH using the determined PHICH resources according to a UE-specific manner and/or a currently used PHICH scrambling code; and the NodeB sends the scrambled PHICH on the determined PHICH resources. Through the disclosure, the problem of PHICH capacity insufficiency, PHICH collisions and interference that caused by the number of user in single cell much larger than that in traditional cell in the related art are solved, the capacity of physical hybrid ARQ indicator channel in downlink resources is improved, and the interference that caused by PHICH collisions is reduced.
