Description
Technical field
The present invention relates to field of wireless communication, relate in particular to a kind of in E-DCH (enhancing-dedicated transmission channel) addressing user equipment method when uploading transmission of common control channel.
Background technology
3GPP (3G (Third Generation) Moblie partnership) is carrying out the standardization effort of the up enhancing of CELL_FACH (sub-district _ forward access channel) state at present.The up enhancing of CELL_FACH state 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.
The E-DCH transmission is exactly usually said HSUPA (high speed uplink packet access), and the physical-layer techniques of HSUPA uses advanced obtains high-transmission efficient.In the version before 3GPP Rel-7, the E-DCH transmission is only used under CELL_DCH (CELL _ DCH) state, with the signaling on DCCH (Dedicated Control Channel) or DTCH (Dedicated Traffic Channel) logic channel or data map to the E-DCH transmission channel, again by the E-DCH channel Mapping to physical channel E-PUCH (enhancing-physical uplink channel).
The E-DCH business can be divided into dispatching services and non-scheduling service by the difference of scheduling mode, wherein the resource of non-scheduling service is that UE (user terminal) distributes by SRNC (service wireless network controller), this resource has periodically and specificity, is suitable for real time business; In dispatching services, be that Node B (Node B) distributes sub-district enhanced uplink resource pool by SRNC earlier, be single UE Resources allocation by Node B again.
When UE was in the CELL_DCH state, the transmission course of E-DCH dispatching services may further comprise the steps as shown in Figure 1:
101:SRNC thinks through admittance control can be for this UE sets up enhanced uplink, so it sets up request by the Radio Link that adopts NBAP (node B application part) agreement or radio link reconfiguration request requirement Node B is that UE sets up the E-PUCH Radio Link;
102:Node B receives configuration parameter, and be this UE distribution E-AGCH (enhancing-absolute grant channel) channel and E-RNTI (enhancing-Radio Link temporary mark) from the up common pool of the enhancing of this sub-district, return to SRNC by Radio Link foundation response or the radio link reconfiguration response of adopting the NBAP agreement;
103:SRNC initiates radio bearer by RRC (Radio Resource control) agreement to UE and sets up request, wherein comprise the E-DCH configuration parameter, as E-AGCH channel configuration, E-RNTI, the configuration that is mapped to the logic channel on the E-DCH, E-TFC (enhancing-TFS Transport Format Set) configuration etc.;
104:UE receives the E-DCH configuration parameter, replys radio bearer foundation to network side and finishes message.Determine that according to the E-DCH configuration parameter current E-DCH transport service is available.Become non-ly 0 the time by 0 when UE is mapped in the logic channel buffering area on the E-DCH data volume, E-RUCCH (strengthen-the inserting ascending control channel at random) random access procedure that UE initiates comprises step 105～107:
105:UE selects to be exclusively used in the uplink synchronous code (SYNC_UL) that E-DCH inserts at random, sends it to Node B by UpPCH (ascending pilot channel) channel;
After 106:Node B detects the uplink synchronous code of UE, send affirmation by FPACH (forward physical access channel) channel;
107:UE selects an E-RUCCH channel to send on the subframe of determining and inserts request at random, wherein carries the E-RNTI of oneself;
After 108:Node B detects the request of access at random of this UE, UE is added among the competition UE group who uses the E-DCH resource, according to the QOS attribute of current resource situation, UE, UE auxiliary dispatching information etc. this UE is dispatched, after distributing adequate resources, send authorization message by the E-AGCH channel to UE, carry the E-RNTI of UE on the CRC of E-AGCH (cyclic redundancy check (CRC) code) field;
After 109:UE detects the E-AGCH that points to oneself, after arriving timing nE-AGCH, UE sends data on the E-PUCH that authorizes, also have a control channel E-UCCH (enhancing-ascending control channel) who follows on E-PUCH, UE carries E-TFCI (indication of enhancing-transformat), HARQ (mix automatically and retransmit) process number and re-transmission sequence number therein;
110:Node B decodes to the control channel of following in the E-PUCH channel, obtains E-TFCI, and data portion is decoded then, and returns ACK/NACK information on E-HICH (E-DCH HARQ confirms indicating channel) channel.
Under the CELL_FACH state, up logic channel comprises CCCH (Common Control Channel), DCCH and DTCH.The RRC signaling that sends on the CCCH channel has:
RRC connection request (RRC Connection Request): initiate by the UE that is in Idle (free time) state;
Cell update (Cell Update) request: initiate by the UE that is in CELL_FACH, CELL_PCH (cell paging channel) and URA_PCH (user registration area _ paging channel) state;
URA upgrades (URA Update) request: initiated by the UE that is in the URA_PCH state.
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.Figure 2 shows that a kind of rational flow process when CCCH is mapped to E-DCH and goes up, this flow process is consistent with initial E-DCH transmission course under the CELL_DCH state, may further comprise the steps:
201-203: be in the UE of Idle state, CELL_PCH or URA_PCH state, when initiating up access, when promptly sending RRC connection request, cell update request or URA update request, at first carry out the uplink random access procedure by the CCCH logic channel.In this process, uplink synchronous code uses and is exclusively used in the synchronous code SYNC_UL that E-DCH inserts at random, UE initiates to insert request at random on the E-RUCCH channel that is associated after receiving the synchronous code affirmation that Node B sends by the FPACH channel, wherein needs to carry the E-RNTI of schedule information and UE;
After 204:Node B detects the schedule information of UE,, and on the CRC of E-AGCH (cyclic redundancy check (CRC) code) field, carry the E-RNTI of UE by E-AGCH channel authorization resource;
After 205:UE detects the E-AGCH that points to oneself, send data on the E-PUCH that authorizes, be to send the Initial R RC signaling that is mapped on the CCCH logic channel herein, and UE can also carry schedule information according to the data volume situation in Frame;
206:Node B confirms by E-HICH on the timing slip of determining;
207:Node B gives SRNC with the E-DCH data forwarding that receives.
When the data of UE on CCCH do not transmit when finishing, Node B can continue by E-AGCH channel dispatch UE, and repeated execution of steps 204～207.
SRNC can send response message after receiving the Initial R RC signaling of UE, such as the RRC connection request for UE, SRNC can send the RRC connection and set up message.In this message, SRNC can be the information (being mapped on the DCCH logic channel) of UE configured radio bearer aspect, and for the relevant resource of UE configuring E-DCH, such as E-RNTI.This moment UE can on E-DCH, reply the RRC connection setup complete message, and can according to the CELL_DCH state under identical E-DCH transmission course transmit.
But because UE does not also have specific configuration information when initial the access, therefore also have some problems to need to solve, comprising: how Node B distributes E-RNTI and how to be addressed to certain specific UE by E-AGCH.Solution commonly used is that Node B broadcasts several public E-RNTI by system broadcast message, UE selects one of them conduct oneself, but this can cause the conflict of E-RNTI, that is: have a plurality of UE and use same E-RNTI simultaneously, cause Node B accurately to be addressed to a concrete UE, and then cause the conflict of authorization resources by the E-AGCH channel.And when having the E-RUCCH channel of one or more in the sub-district, this E-AGCH channel still might be received by a plurality of UE, can cause the fuzzy problem of UE addressing equally.
In existing TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system, the random access channel resource in E-RUCCH and traditional PRACH (Physical Random Access Channel) sharing system, 2 kinds are inserted by synchronous code at random and distinguish.Synchronous code in the sub-district is divided into 2 groups, and one group is exclusively used in PRACH and inserts; Another group is exclusively used in E-RUCCH and inserts.System can dispose many FPACH channels, and a FPACH channel is related with many Random Access Channel.
According to the existing algorithm that inserts at random, in step 201～203, after UE sends the uplink synchronous code of E-DCH special use, select a FPACH channel interception confirming information according to following rule.
Rule one: the corresponding relation of uplink synchronous code and FPACH channel number satisfies: i=N mod M.
Wherein N represents the synchronous code numbering, available FPACH total number of channels during the random access resource that on behalf of UE, M use disposes, and i represents the channel number of selected FPACH.
After Node B detects the synchronous code of UE, send affirmation to UE on the FPACH channel, NodeB can only confirm a UE on a FPACH channel in a subframe, and the selection of FPACH also obtains according to rule one.
When UE after listening to confirmation on the FPACH channel of selecting according to rule one, it also needs to select an E-RUCCH channel to initiate to insert at random request to Node B.The incidence relation of FPACH channel and E-RUCCH interchannel should satisfy following regular two:
Rule two: selected i bar FPACH channel FPACH
iSubframe numbers SFN ' and the channel number of selected E-RUCCH satisfy following relation:
Wherein, n
E-RUCCHiBe the channel number of selected E-RUCCH, N
E-RUCCHiFor with FPACH
iThe number of the E-RUCCH channel that is associated, its value is not more than L
EiL
EiBe the E-RUCCH transport block length, general value is 1,2, and unit is a subframe; SFN ' is that UE is at FPACH
iOn receive system's subframe numbers when confirming.
Select FPACH according to rule two
iBehind the E-RUCCH channel that is associated, UE is receiving that NodeB passes through FPACH
iAfter the synchronous code of its transmission is confirmed, in second subframe, send the request that inserts at random to Node B.When the E-RUCCH transport block length is odd number greater than the subframe numbers of 1 and second subframe, wait for that again a subframe launches above-mentioned request.
The rule of using from above random access procedure two as can be seen, in a subframe, article one, the FPACH channel can only be confirmed the access of a UE, thereby with E-RUCCH channel theory that a FPACH channel is associated on resource contention can not take place, that is: an E-RUCCH channel only may be used by a UE at synchronization, and it is shared by the UE timesharing in the sub-district.The present invention will provide under the CELL_FACH state addressing method of UE on the CCCH channel based on this.

Embodiment
Below in conjunction with drawings and Examples technical scheme of the present invention is described in detail.
On the basis of inserting algorithm at random of the present invention in existing system, further reach the effect of Node B energy correct addressing to UE by the sequential relationship of setting up E-AGCH channel and E-RUCCH channel.As shown in Figure 3, may further comprise the steps: at first determine the incidence relation of one or more an E-AGCH channel and an E-RUCCH channel, UE only intercepts the E-AGCH channel that is associated with the E-RUCCH channel of oneself selecting like this; And then determine that by the sequential relationship of setting up E-AGCH channel and the E-RUCCH interchannel related this E-AGCH channel is to issue at certain specifically to send the UE that inserts request at random by the E-RUCCH channel constantly, just can avoid the fuzzy problem of UE addressing fully with it.
Under the method for the invention, the E-RNTI that UE sends can be based on public E-RNTI strategy, and promptly Node B broadcasts one or more E-RNTI in cell system message.Adopt the consistency on the flow process under E-DCH transmission that this method can keep the CCCH channel and the CELL_DCH state; And can share the E-AGCH channel resource under the CELL_DCH state.UE therefrom selects the E-RNTI of a conduct oneself according to certain rule, and the rule of selection can be any one in following two kinds:
1. select one of them at random;
Select one 2.UE use ID (IMSI (international mobile subscriber identity)/TMSI (temporarily moved subscriber the identification)) delivery of oneself: IMSI (TMSI) %K=k, wherein K is public E-RNTI sum; K is the sequence number of selected E-RNTI, and this sequence number is corresponding to the configuration sequence of public E-RNTI in the system message, from 0 open numbering.
Can determine sequential relationship between E-AGCH and the E-RUCCH related by in following two kinds of methods any one with it:
Method 1: fixing sequential relationship.Send the sequential relationship that inserts at random between the request by system configuration or by agreement agreement E-AGCH channel transmission authorization message and related with it E-RUCCH channel, such as between the two every how many subframes or how many time slots at interval, and determining that good back is broadcast to UE by system message, makes it be kept at UE side and Node B side.UE detects related with it E-AGCH channel on the sequential of regulation successfully send access request at random by the E-RUCCH channel after, if wherein comprise oneself selected public E-RNTI on an E-AGCH channel, just think to issue oneself; If do not detect, not success of this authorized application then is described, UE can consider to initiate again to insert at random request;
Method 2: sequential relationship flexibly.On the E-AGCH channel, add time sign, Node B is carrying this time marking by this E-AGCH channel when UE sends authorization message, this time marking is used for indicating this to authorize at the request of access at random on which subframe and the E-RUCCH channel that this E-AGCH channel is associated, UE need be after initiating to insert request at random, this E-AGCH channel of continuous detecting, if comprised the public E-RNTI of own selection on the E-AGCH channel, also need basis time marking wherein to judge whether it is one's own mandate.
Set up incidence relation and set up that the E-AGCH channel sends authorization message and the E-RUCCH channel sends the sequential relationship that inserts at random between the request by E-AGCH channel and E-RUCCH channel, can solve the CCCH channel Mapping and make Node B can't be addressed to the problem of UE owing to lacking specific configuration information to the E-DCH channel the time.
More than be the principle explanation, specify with an application example below that in this example, the sequential that E-AGCH authorizes and E-RUCCH inserts between the request is at random disposed by high level.
High-rise at first need to dispose CCCH channel Mapping required information element when E-DCH goes up, and be broadcast to UE by system message, information related to the present invention as shown in Table 1 and Table 2.

Related to the present invention in the table 1 is " E-RUCCH-E-AGCH information " information element, and this element is 2 groups of E-AGCH channels of configuration at most down, and article one E-RUCCH channel in first group and " code resource information " is associated; Second E-RUCCH channel in second group and " code resource information " is associated.Can dispose maximum maxE-AGCH bar E-AGCH physical channels in every group of E-AGCH channel configuration again.At main carrier maximum 16 random access resource profile instance are arranged in the system information at present, all should have the information element shown in the table 1 in each profile instance; Configuration on the auxilliary carrier wave is identical with the collocation method on the main carrier.
The public E-RNTI resource of table 2
| The E-RNTI tabulation | 1..<maxComm onERNTI> | MaxCommonERNTI: the public E-RNTI number of maximum configurations |
| E-RNTI information | The integer of 16 bits |
The E-AGCH channel resource is selected from the public E-AGCH resource pool in sub-district by Node B, and broadcasts in system message by SRNC tissue back.Incidence relation between E-AGCH and the E-RUCCH is determined by Node B, can pass through Iub (interface between a kind of SRNC and the Node B) interface NBAP (Node B Application Part, Node B applying portion) the Physical Shared Channel reconfiguration course in disposes to SRNC, and SRNC sends to UE by system message with this incidence relation.Node B and UE will follow same channels associated relation and carry out the transmission and the reception of channel.
For the sequential relationship between E-RUCCH and the E-AGCH, if adopt fixing sequential relationship, need so to dispose a timing value for UE, be embodied in the table 1 is Te-agch, it is that E-RUCCH inserts the time interval between request and the E-AGCH mandate at random, reflected the dispatching and the scheduling frequency of system, this value can be selected also can be disposed by SRNC by Node B, finally also broadcasts in system message.If selected by SRNC, Te-agch needs configuration simultaneously to give Node B.When the E-DCH transmission that allows on a plurality of frequencies in the sub-district to carry out under the CELL_FACH state, should dispose the E-AGCH channel resource on a plurality of frequencies respectively.
If when the timing relationship of E-AGCH and E-RUCCH adopts second kind of flexible way, do not need to dispose Te-agch in the system message, time relationship should be pointed out by the E-AGCH channel.The information field EGSN that one 3 bit is arranged in the existing E-AGCH channel, be what to be used for the power control of E-AGCH channel, this field can't be used when public E-RNTI transmits, can be used as the time indication, if by subframe is unit, the information of 8 subframes before can indicating at most is during such as EGSN=1, can represent that this authorizes scheduling application in the last subframe relevant (when E-RUCCH Channel Transmission is crossed over subframe more than 1, should be that benchmark is indicated with first subframe).Also can do more expansion, such as the sequential relationship between E-RUCCH and the E-AGCH be: the value of T1+EGSN indication, wherein T1 is a fixed value.Such as system T1=7 is set, the interval between E-RUCCH and the E-AGCH is always more than or equal to 7 so.
UE need obtain above relevant information before initiating the CCCH transmission.Fig. 4 is a concrete CCCH data transmission procedure, this process based on prerequisite be that the sub-district is supported CCCH to be mapped to E-DCH to go up transmission, and UE has the E-DCH transmittability; E-AGCH channel and E-RUCCH interchannel adopt fixing sequential relationship in this example:
When 401:UE need initiate the RRC connection, UE selected a carrier wave, and selected to be exclusively used in the synchronous code that E-RUCCH inserts on this carrier wave, sent this synchronous code on available UpPCH subchannel; UE selects a FPACH channel according to rule 1, is designated as FPACHi;
After 402:Node B detects synchronous code, selected the FPACHi channel, and on the subframe that satisfies rule 2, sent affirmation by rule 1;
The n bar E-RUCCH channel that 403:UE is associated with FPACHi according to rule 2 selections, and from system information, select a public E-RNTI at random.UE fills the information in the E-RUCCH channel, and is with selected public E-RNTI;
After 404:Node B receives the E-RUCCH channel, after Te-agch subframe on send authorization message (here also can by the E-RNTI of E-AGCH channel allocation special use) by the E-AGCH channel that is associated with this E-RUCCH channel, this moment, UE can receive the E-AGCH channel that carry own selected E-RNTI by same timing agreement;
Detect the E-AGCH channel on Te-agch the subframe of 405:UE after sending E-RUCCH, after containing own selected E-RNTI on it, on the resource of authorizing, send data, be to send the Initial R RC signaling that is mapped on the CCCH logic channel, UE can also carry schedule information according to the data volume situation in Frame herein;
406:Node B confirms on the timing slip of determining;
407:Node B gives SRNC with the E-DCH data forwarding that receives.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
