Replacedly, node-b 420 and CRNC 430 can be configured to each and be in WTRU under the Cell_FACH state and be independent of the E-DCH resource and keep separately enhancement mode MAC-e and MAC-es entity.
Replacedly, node-b 420 and CRNC 430 can be configured to be WTRU 410 distribution and transmit E-DCH radio net temporary identifier (E-RNTI) and set up enhancement mode MAC-e and enhanced MAC-es entity afterwards at node-b 420.
In some cases, SRNC 440 may not know the identifier of WTRU 410 before the first transmission of WTRU 410, and this is defeated for the first time to be after receiving acquisition indicator channel (AICH) or E-AICH.In this case, can be configured to when WTRU-ID is read from header be that WTRU 410 sets up enhanced MAC-es to SRNC 440.Thus, need new Iub signaling process to set up the enhanced MAC-es entity for given WTRU with indication SRNC 440.
When for after given connection sets up public enhancement mode MAC-e and/or enhanced MAC-es resource, they can be used as Common transport channel between RNC and the Node B 420 and set up the part of process and be established.
Fig. 6 is the flow chart of method, wherein CRNC 430 is pre-configured and store public enhanced MAC-es entity, and can be assigned to enhancement type special channel (E-DCH) resource collection of WTRU after E-RACH inserts process pre-configured and store public enhancement mode MAC-e entity and node-b 420 is for each.With reference to figure 6, CRNC determines that the E-DCH resource collection informs node-b (610) with signal.CRNC and node-b are respectively each available E-DCH resource collection pre-configured and public enhanced MAC-es of storage and enhancement mode MAC-e entity (620).WTRU carries out and inserts process at random to obtain E-DCH resource collection (630).Under idle pulley, use the E-DCH set to receive RRC connection request message, (640) that described E-DCH set is to use access process at random to obtain from WTRU.Node-b distributes E-RNTI.And in SRNC, set up enhanced MAC-es entity (650) for WTRU.
Since the enhancement mode MAC-e entity of the enhanced MAC-es of CRNC and node-b for the E-DCH resource collection by pre-configured, the enhancement mode MAC-e that is used for CCCH can be configured to the work the same with public entities that once is associated to a WTRU (promptly being used to receive the WTRU of E-RACH access) with enhanced MAC-es.In a kind of selection, public enhancement mode MAC-e and MAC-es entity can only be used to the initial service of WTRU.Replacedly, can WTRU via with the corresponding E-DCH resource collection of enhancement mode MAC entity communicate whole during use enhancement mode MAC entity.Then, the RRC connection setup complete message can be received with indication WTRU and be in connection mode (660).
Enhanced MAC-es entity among the CRNC can be associated with the common E-DCH resource collection that WTRU 410 uses, and perhaps is associated with the public E-RNTI that is selected by WTRU 410.SRNC440 can be configured to each WTRU that works and set up special-purpose enhanced MAC-es entity under the Cell_FACH state, described WTRU is registered and is assigned with E-RNTI, and described entity can be held during WTRU is in the Cell_FACH/CelLL_PCH state of DTCH/DCCH business at least.For the DTCH/DCCH business, at first with public enhancement mode MAC-e entity that the employed common E-DCH resource of UE is associated in receive data, then by the Iub/Iur interface with the special-purpose enhanced MAC-es entity of described data forwarding to the SRNC.Therefore, when enhancement mode MAC-e was public entities for the WTRU of any use resource collection, the process by Iub/Iur Frame Protocol identification WTRU-ID needed.Be described in more detail below some and replaced execution mode.
Replace in the execution mode at first kind, node-b 420 can be configured to use Iub stream to transmit data in (for use the WTRU of E-DCH under the Cell_FACH state) on the Common transport channel.Because Iub is a common flow, so CRNC 430 can receive data from this common flow of each WTRU, and do not know which WTRU is these data belong to.Therefore, when enhanced MAC-es was associated with the specific WTRU that is in Cell_FACH state (that is, being used for the DTCH/DCCH business), node-b 420 can be configured to transmit WTRU-ID in the header field of Iub frame.Similarly, CRNC
430 can be configured to transmit WTRU-ID in the header of Iur frame.WTUR-id can comprise E-RNTI or comprise S-RNTI when transmitting via the Iur interface when transmitting via Iub interface.This will allow SRNC 440 data to be sent to the appropriate forwarding address of correct special-purpose enhanced MAC-es entity for WTRU identification.
Replace in the execution mode at another kind, WTRU-id can comprise one among E-RNTI, U-RNTI, C-RNTI or the S-RNTI or its combination.For the CCCH business, do not have WTRU-id, so the Iub Frame Protocol can not comprise E-RNTI.CRNC 430 can be configured to that the detection business belongs to the CCCH business from logical channel identifier, and forwards the data among the CRNC 430 the correct enhanced MAC-es entity that is associated with appropriate E-DCH resource.In an optional execution mode, there is a Common transport channel and a transmission channel that is used for the CCCH business that is used for the DTCH/DCCH business for each E-DCH resource collection foundation.Node-b 420 can be configured to receive the CCCH business and forward the data to the transmission channel that is associated with the enhancement mode MAC-e entity that receives data.
Replace in the execution mode at another kind, when node-b 420 and CRNC 430 were configured to set up public enhancement mode MAC-e and enhanced MAC-es entity, WTRU 410 can be configured to transmit WTRU-id in the enhanced MAC-es header of enhanced MAC-es PDU.Node-b 420 can further be configured to have decomposing module, and this decomposing module can be decoded and definite WTRU-id to enhanced MAC-es PDU header.By transmission information in enhanced MAC-es PDU, node-b 420 does not need to transmit the Iub frame with WTRU-id information.For example, WTRU 410 can be configured to only transmit WTRU-id at the enhanced MAC-es header during the initial transmission that is used for the contention resolution purpose.In this case, node-b 420 can be configured to enhancement mode MAC-e entity, and this enhancement mode MAC-e entity uses initial transmission for determining the forwarding process in the continuous data to the subsequent transmission of RNC.WTRU 410 can transmit WTRU-id, receives the absolute grant of E-DCH channel up to WTRU 410, and this moment, WTRU 410 can stop to transmit WTRU-id.
Replace in the execution mode at another, node-b 420 can be configured to receive WTRU-id and extract WTRU-id from first transmission from WTRU.Node-b 420 can be stored WTRU-id then, and uses this information to utilize the Iub signaling that WTRU-id is sent to SRNC 440 or CRNC 430 in follow-up transmission.When WTRU 410 discharged the E-DCH resource collection, node-b 420 can be configured to remove this WTRU-id.Replacedly, if follow-up E-RACH access attempts is performed, and different WTRU-id is decoded, and then node-b 420 can change the WTRU-id information of storage to show new WTRU-id.
One replacing in the execution mode, after node-b 420 received first transmission from WTRU, node-b 420 can use first transmission to belong to which WTRU with specified data again.In case WTRU-id is determined, node-b 420 can WTRU be connected to the E-DCH resource during be set up to half dedicated stream of RNC.Between public enhancement mode MAC-e and special-purpose enhanced MAC-es, set up the interim stream that is connected like this.This can set up by transmitting the Iub signaling, and this signaling is used to inform that RNC begins to set up public enhancement mode MAC-e corresponding with WTRU and the stream between the enhanced MAC-es entity.In this case, unnecessaryly specify WTRU-id in the Iub Frame Protocol, because WTRU-id is present in the enhancement mode MAC-e header of each transmission, and information is forwarded to RNC via the Iu Frame Protocol.
Replacedly, because the E-DCH resource can not held consultation by RNC between node-b 420 and WTRU, therefore function, for example enhanced MAC-es relevant with E-DCH can be moved to node-b 420.For this execution mode, logical channel flow can be set up between enhanced MAC-es and radio link control (RLC) entity.Replacedly, WTRU 410 and node-b 420 can be set up Common transport channel, and WTRU-id and linear channel (LCH) ID can transmit by Iub and/or Iur Frame Protocol.
