Description
Technical field
The present invention relates to field of wireless communication, relate in particular to the method for when E-DCH (enhancing-dedicated transmission channel) goes up transmission CCCH (Common Control Channel) signaling, how to distribute MAC (medium access control) entity under a kind of CELL_FACH (sub-district _ forward access channel) state.
Background technology
The standardization effort that 3GPP (3G (Third Generation) Moblie partnership) is carrying out the up enhancing of CELL_FACH state at present.The up enhancing of CELL_FACH makes it obtain less packet transfer delay and higher transmission rate by introducing the ascending packet data transmission performance that the E-DCH transmission channel strengthens this state at the CELL_FACH state.
In the version before 3GPP Rel-7, the E-DCH transmission is only used under CELL_DCH (CELL _ DCH) state, signaling on DCCH (Dedicated Control Channel) or DTCH (Dedicated Traffic Channel) logic channel or data map are mapped on E-PUCH (enhancing-physical uplink channel) physical channel to the E-DCH transmission channel again.The E-DCH business is divided into dispatching services and non-scheduling service by the difference of scheduling mode, and wherein the resource of non-scheduling service is that UE (user terminal) distributes by SRNC (service wireless network controller), and resource has periodically and specificity, is suitable for real time business; In dispatching services, be that Node B (base station) distributes sub-district enhanced uplink resource pool by SRNC, be single UE Resources allocation by Node B.
When under the CELL_FACH state, carrying out the E-DCH transmission,, thereby can only carry out dispatching services because this state is not supported dedicated link.The workflow of having determined at present in WCDMA (Wideband Code Division Multiple Access (WCDMA) access) is:
System broadcasts is organized the common E-DCH resource more, maximum 32 groups, comprise F-DPCH (fractional dedicated physical channel) configuration, E-AGCH (E-DCH absolute grant channel) configuration, E-HICH (E-DCH HARQ confirms indicating channel) configuration, up DPCH (DPCH) configuration etc. in every group of resource.When UE needed transmit ascending data, UE initiated random access procedure, wherein used the signature sequence of E-DCH special use; After Node B side detected the access at random of UE, UE, wherein a group in 32 groups of public resources of public resource index point given in feedback public resource index on AICH/E-AICH (confirming indicating channel/enhancing-affirmation indicating channel) channel.UE sends data on the common E-DCH resource of authorizing behind the fixed time interval of determining.When UE sends last packet, UE is send state information behind the timing of network side configuration, and wherein indicating buffer state is 0, confirms when all packets that sent obtain ACK then, or after reaching number of retransmissions, UE discharges the common E-DCH resource.Because may there be the competition conflict in the receiving course of the transmission of signature sequence and AICH/E-AICH, thereby same public resource may use by the UE more than 1 simultaneously, and in order to address this problem, system has formulated a cover contention resolution; To the CCCH transmission channel, because its resource occupation limited time, thereby application collision solution not, as MAC-c (public medium access control entity) PDU (Protocol DataUnti, when protocol Data Unit) carrying out segment transmissions, in order to prevent to receive data from different UEs, MAC-c PDU need add CRC (Cycle Redundant Check, cyclic redundancy check (CRC)) check field, Node B can detect to determine that whether this MAC-c PDU is from a UE by CRC when resource contention takes place like this.
UTRAN (UMTS Terrestrial Radio Access Network, universal mobile telecommunications system grounding wireless access network network) side is finished the E-DCH transfer function by MAC-i (enhancing medium access control entity) entity and MAC-is (strengthening medium access control fructification) entity, is the major function that example is introduced these 2 functional entitys with the transfer of data of CCCH channel:
MAC-i: be arranged in Node B, to carry out demultiplexing from the MAC-i PDU that eats dishes without rice or wine to receive, obtain one or more MAC-is PDU, and on the public MAC of Iub (protocol interface between Node B and the RNC) interface (medium access control) stream, these MAC-is PDU are transferred to CRNC (Controlling Radio Network Controller, radio network controller) by the E-DCH Frame; Also be responsible for scheduling of resource and HARQ (Hybrid Automatic Repeat Request mixes automatically retransmitting) function at the MAC-i entity of eating dishes without rice or wine.The relation of MAC-i PDU and MAC-is PDU as shown in Figure 1.
MAC-is: be arranged in CRNC, receive the E-DCH Frame, take out MAC-is PDU wherein, send into the unit that reorders of this UE correspondence from public MAC stream.Reorder the unit by the logic channel setting, and in the transmission of CCCH signaling, an obvious UE only needs the unit that reorders.After the cell processing that reorders, the MAC-is PDU that transmits Sequence Number continuous is fed to resolving cell, removes the PDU head in resolving cell, obtains the segmentation of one or more MAC-c PDU or MAC-c PDU; Send into the reorganization entity then, the MAC-c PDU with segmentation in the reorganization entity re-assemblies, and sends into CRC error correction entity, and after CRC check was correct, MAC-c PDU can be sent to upper strata MAC-c entity.MAC-is functional structure during the CCCH transmission as shown in Figure 2.
Wherein public MAC stream is the transmission bearer that transmits the CCCH signaling data between Node B and the RNC, and two ends connect MAC-is and MAC-i entity.
Have in the RRC that on the CCCH channel, sends under the CELL_FACH state (Radio Resource control) signaling:
The connection request that RRC connection request (RRC Connection Request): UE initiates at Idle (free time) state;
Cell update (Cell Update): the cell update that the UE of CELL_FACH, CELL_PCH and URA_PCH state initiates;
URA (UTRAN Registration Area territory) upgrades (URA Update): the UE of URA_PCH state initiates to upgrade.
When these signalings of transmission, UE does not have special-purpose configuration information, there is not special-purpose E-RNTI (enhancing-Radio Network Temporary Identifier), Node B receives behind the MAC-i PDU of a carrying CCCH channel signaling and does not know concrete user profile, after wherein MAC-is PDU issued CRNC by public MAC circulation, CRNC also can't find the unit that reorders of this UE correspondence, thereby needs a kind of mechanism to determine the MAC-i of UE and the communication means of MAC-is entity and inter-entity.
