Method of perceptual transfer channel and means for multiplexing ePHICH

The present invention provides a method and apparatus for channel aware ePHICH transmitted multiplexed in the communication system, wherein the ePHICH predetermined number of resource elements occupied, and which carries the HARQ ePHICH? ACK / NACK information bits. By a preferred aspect of the present invention, the channel quality level resource element groups arranged orthogonal sequences to provide a suitable distance coding, so as to maintain robustness to ensure correct data transmission, in order to improve the efficiency of resource allocation and flexibility. On the other hand, according to the number of resource elements may be allocated to the ePHICH, the length of resource element groups arranged orthogonal sequence level, to further improve the transmission efficiency and flexibility of multiplexing. Further, by establishing a correspondence relationship with the ePDCCH ePHICH user terminal so ePHICH ePDCCH may share the same antenna port, thereby can share the same configuration and signaling, i.e. signaling set may be shared with ePHICH configured ePDCCH antenna, thereby reducing overhead costs.
