METHOD AND APPARATUS FOR RESOURCES MAPPING OF PHYSICAL HYBRID ARQ INDICATOR CHANNEL

摘要

A method and apparatus for resources mapping of Physical Hybrid ARQ Indicator Channel (PHICH) are provided in the present invention. The method and apparatus are used in Uplink Single-User Multiple Input Multiple Output (UL SU-MIMO) transmission scene. The method includes: a Base Station (BS) determining dynamic cyclic shift parameters of Demodulation Reference Signal (DMRS) according to a codeword stream index and/or a dynamic cyclic shift amount of the DMRS in Downlink Control Information (DCI) for uplink scheduling and/or layer index; the BS realizing resources mapping of the PHICH according to the determined dynamic cyclic shift parameters. With the subject-matter of the present invention, the resources mapping of the PHICH in MIMO scene could be effectively realized.
