Claim Text:
1. A hybrid automatic repeat request (HARQ) failure indication method, which is used in a dual-carrier system to indicate HARQ failures, wherein the method comprises: when decoding of a received enhanced dedicated transport channel (E-DCH) data frame is unsuccessful and a condition of sending an HARQ failure indication is satisfied currently, a serving node B sending an HARQ failure indication data frame to a service radio network controller (SRNC), wherein, a carrier identifier which indicates a carrier on which the HARQ failure happens is carried in the HARQ failure indication data frame; wherein parameters carried in the HARQ failure indication data frame also comprise: a connection frame number, a subframe number and the number of HARQ retransmissions at the time of HARQ failure on the carrier; wherein the serving node B carries the carrier identifier in the HARQ failure indication data frame in the way of: the serving node B carrying the carrier identifier by a carrier indicator field of the HARQ failure indication data frame, wherein, the carrier indicator field is located at any spare field of the HARQ failure indication data frame or at a spare extension of the HARQ failure indication data frame.
