Abstract:
1. A method for transmitting a Hybrid Automatic Repeat Request (HARQ) failure indication, applied to a process of transmitting data flows of a primary carrier and a secondary carrier on independent transmission bearers of a Iub interface/Iur interface respectively, comprising: receiving an Enhanced Dedicated Transport Channel (E-DCH) payload from the primary carrier and failing to decode it by a Node B; determining by the Node B whether a condition for transmitting an HARQ failure indication is met, if it is met, setting by the Node B an HARQ failure indication data frame on the primary carrier; and binding by the Node B the HARQ failure indication data frame with a transmission bearer corresponding to the primary carrier and transmitting by the Node B the HARQ failure indication data frame to a Service Radio Network Controller (SRNC) on the transmission bearer corresponding to the primary carrier; wherein the setting an HARQ failure indication data frame on the primary carrier comprises: setting a Connection Frame Number CFN domain and a subframe number domain as a CFN and a subframe number when detecting an HARQ failure indication; if the data frame is of type if the data frame is of type setting an HARQ retransmission number domain as the number of HARQ retransmissions having happened when an HARQ failure indication is detected.
