Abstract:
1. A method for transmitting multi-carrier enhanced dedicated channel data, comprising a first sending step and a first receiving step, wherein: the first sending step comprises: when a node B only has an enhanced dedicated channel cell of a single carrier frequency layer in multi-carrier, the node B setting “uplink multiplexing information” in an enhanced dedicated channel uplink data frame to be “null” and sending the enhanced dedicated channel uplink data frame to a serving radio network controller; the first receiving step comprises: the serving radio network controller receiving the enhanced dedicated channel uplink data frame sent by the node B of a sender which only has the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, the serving radio network controller distinguishing which carrier in the multi-carrier is a carrier for receiving data carried in the enhanced dedicated channel uplink data frame based on carrier identifier information corresponding to a carrier frequency of an enhanced dedicated channel cell recorded when the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier is established or added in advance; or the method comprising: a second sending step, a relaying step and a second receiving step: the second sending step comprising: when a node B only has an enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, the node B setting “uplink multiplexing information” in the enhanced dedicated channel uplink data frame to be “null” and sending the enhanced dedicated channel uplink data frame to a drift radio network controller; the relaying step comprising: the drift radio network controller receiving the enhanced dedicated channel uplink data frame sent by the node B which only has the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier; and if all the nodes B governed by the drift radio network controller are nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier and are in an identical carrier frequency layer, the drift radio network controller not processing the received enhanced dedicated channel uplink data frame and sending the received enhanced dedicated channel uplink data frame to the serving radio network controller; if all the nodes B governed by the drift radio network controller are nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier but do not belong to an identical carrier frequency layer, or all the nodes B governed by the drift radio network controller are not all nodes B of the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, the drift radio network controller setting the “uplink multiplexing information” which is “null” in the received enhanced dedicated channel uplink data frame as carrier identifier information of the carrier for receiving data carried in the enhanced dedicated channel uplink data frame and sending that enhanced dedicated channel uplink data frame to the serving radio network controller; the second receiving step comprising: the serving radio network controller receiving the enhanced dedicated channel uplink data frame sent by the drift radio network controller of a relay party which only has the enhanced dedicated channel cell of a single carrier frequency layer in the multi-carrier, the serving radio network controller distinguishing which carrier in the multi-carrier is a carrier for receiving data carried in the enhanced dedicated channel uplink data frame based on carrier identifier information corresponding to the carrier frequency of the enhanced dedicated channel cell recorded when the enhanced dedicated channel cell of the single carrier frequency layer in the multi-carrier is established or added in advance; wherein the second sending step further comprises: when the node B has an enhanced dedicated channel cell of frequency layers of any two or more carriers in the multi-carrier, the node B setting “uplink multiplexing information” in the enhanced dedicated uplink data frame as carrier identifier information of a carrier for receiving data carried in the enhanced dedicated channel uplink data frame; the node B sending the enhanced dedicated channel uplink data frame to the drift radio network controller; the relaying step further comprises: the drift radio network controller receiving the enhanced dedicated channel uplink data frame sent by the node B which has the enhanced dedicated channel uplink data frame of frequency layers of any two or more carriers in the multi-carrier, the drift radio network controller not processing the received enhanced dedicated channel uplink data frame and sending the received enhanced dedicated channel uplink data frame to the serving radio network controller; the second receiving step further comprises: the serving radio network controller receiving the enhanced dedicated channel uplink data frame sent by the drift radio network controller of the relay party of the sender which has the enhanced dedicated channel cell of frequency layers of any two or more carriers in the multi-carrier, the serving radio network controller distinguishing which carrier in the multi-carrier is a carrier for receiving data carried in the enhanced dedicated channel uplink data frame based on the carrier identifier information indicated by “uplink multiplexing information” in the enhanced dedicated channel uplink data frame.
