Description

Method of addressing and finding address of user terminal during transmitting of enhanced-special transmitting channel
The addressing of enhanced-dedicated transmission channel user terminal during transmission and addressing method
Technical field
The present invention relates to field of wireless communication, more particularly to a kind of CELL-FACH (cells-forward access channel）In E-DCH (enhanced-dedicated transmission channels under state）Upper transmission CCCH (CCCHs）When UE (user terminal) addressing and addressing method.
Background technology
3GPP (3G (Third Generation) Moblie partnership) currently carries out the up enhanced standardization effort of CELL-FACH state.The up enhancings of CELL-FACH in CELL-FACH state by introducing E-DCH (enhanced-dedicated transmission channels）Transmission channel strengthens the uplink packet data transfer performance of the state, it is obtained less packet transfer delay and higher transmission rate.
HSUPA (the high speed uplink packet access that E-DCH transmission is just known as）, HSUPA obtains high efficiency of transmission with advanced physical-layer techniques.In the version before 3GPP Rel-7, E-DCH transmission is only used under CELL-DCH (cell-dedicated channel) state, DCCH (DCCH) or DTCH (Dedicated Traffic Channels）Signaling or data on logic channel are mapped on E-DCH transmission channels, re-map E-PUCH (enhancings-physical uplink channel）On physical channel.E-DCH business is divided into scheduling business and non-scheduling service by the difference of scheduling mode, and wherein the resource of non-scheduling service is by SRNC (service wireless network controllers）For UE (user terminals）Distribution, non-scheduling service resource has periodicity and specificity, is suitable for real time business；It is that Node B (node B) distribute cell enhanced uplink resource pool by SRNC in scheduling business, is that single UE distributes resource by Node B.
E-DCH scheduling business transmitting procedure under CELL-DCH states is as shown in Figure 1.
101 :SRNC thinks can be that the UE set up enhanced uplink by call access control, passes through NBAP (Node B Application Protocol, node B application protocols）The wireless link or wireless links reconfiguration course of agreement require that node B is that UE sets up E-PUCH Radio Links；
102:Node-B receiver configuration parameter, and distribute E-AGCH (enhancings-absolute grant channel from the up common pool of the enhancing of the cell for the UE）Channel and E-RNTI (enhancings-Radio Network Temporary Identifier）, returned to by NBAP wireless link response or radio link reconfiguration response
1 180900638 SRNC;
103:SRNC passes through RRC (Radio Resource Control, wireless heterogeneous networks）Agreement initiates radio bearer to UE and sets up order（Radio bearer sets up request）, wherein including E-DCH configuration parameters, such as E-AGCH channel configurations, E-RNTI, the configuration for the logic channel being mapped on E-DCH, E-TFC (enhancings-TFS Transport Format Set）Configuration etc.；
104:UE receives radio bearer and sets up request, obtains configuration parameter, is set up to network side reply radio bearer and completes response message.UE determines that current E-DCH transmission services are available according to configuration parameter；When the logic channel Slow that UE is mapped on E-DCH is rushed data volume is changed into non-zero from 0 in area when, UE initiate E-RUCCH (enhancings-Stochastic accessing ascending control channel）Random access procedure, Stochastic accessing includes step 105-107:
105:UE selects to be exclusively used in the uplink synchronous code of E-DCH Stochastic accessings（SYNC-UL), pass through UpPCH (ascending pilot channels）Channel is sent；
106:Node B are detected after UE uplink synchronous code, pass through FPACH (physical access channels）Channel, which is sent, to be confirmed； 107:UE select an E-RUCCH channel it is determined that subframe on send dispatch request（Random access request）, wherein carrying the E-RNTI of oneself;
108:Node B is detected after the random access request of the UE, UE is added into striving unexpectedly in UE groups using E-DCH resources, according to current resource situation, UE QoS (Quality Of Service, service quality）Attribute, UE auxiliary dispatching information etc. are scheduled to the UE, are distributed after suitable resource, send the E-RNTI that UE is carried on authorization message, E-AGCH to UE by E-AGCH channels;
109:UE, which is detected, to be pointed to after the E-AGCH of oneself, in timing nAGCHAfterwards, UE sends data on the E-PUCH of mandate, also has an adjoint control channel E-UCCH on E-PUCH
(enhancing-ascending control channel）, UE carries E-TFCI wherein, and (enhancing-transformat is indicated）, HARQ (hybrid automatic repeat-requests）Process number and re-transmission sequence number；
110:Node B is decoded to the adjoint control channel in E-PUCH channels, obtains transport format information, then data portion is decoded, and (E-DCH HARQ confirm to indicate channel in E-HICH）ACK/NACK (confirmation/repeating transmission) information is returned on channel.
Up logic channel includes CCCH (CCCHs under CELL-FACH state）、DCCH
2 180900638 And DTCH.The RRC signaling sent on CCCH channels has：
RRC connection request（ RRC Connection Request ) ：UE is (idle in Idle）The connection request that state is initiated；
Cell update（ Cell Update )：CELL_FACH, CELL PCH (cells-PCH）With URA-PCH (UTRAN universal terrestrial access networks Acceditation Areas-PCH）The cell update that the UE of state is initiated；
URA updates（ URA Update ) ：The UE of URA PCH states initiates to update.
When carrying out E-DCH transmission under CELL-FACH state, because the state does not support dedicated link, business thus can only be scheduled, Fig. 2 is that CCCH is mapped into a kind of rational flow when on E-DCH, and the flow is consistent with the initial E-DCH transmitting procedures under CELL-DCH states.
201-203:UE in Idle states or in CELL-PCH, URA PCH states, will initiate multi-upstream access, i.e., when sending RRC connection request or cell update request or URA renewals by CCCH logic channels, uplink random access procedure is carried out first.During being somebody's turn to do, uplink synchronous code uses the synchronous code for being exclusively used in E-DCH Stochastic accessings, UE is received after the synchronous code confirmation that Node B are sent on FPACH channels, and Stochastic accessing is initiated on associated E-RUCCH channels, wherein needing to carry schedule information and UE E-RNTI.
204:Node B are detected after UE dispatch request, by E-AGCH channel authorization resources, and UE E-RNTI is carried on E-AGCH.
205:UE, which is detected, to be pointed to after the E-RNTI of oneself, and data are sent in the resource of mandate, is to send the Initial R RC signalings being mapped on CCCH logic channels herein, UE can also carry schedule information in a data frame according to data volume situation.
206:Node B it is determined that timing slip on confirmed.
207:Node B are by the E-DCH data forwardings of reception to RNC.
When data of the UE on CCCH do not transmit completion, Node B may proceed to continue to dispatch UE by E-AGCH channels, and continue the process of the above 204-207.
RNC can send response message, such as the RRC connection request for UE after UE Initial R RC signalings are received, and RNC can send RRC connections and set up message.Within the message, RNC (can be mapped on DCCH logic channels for the information in terms of UE configuration signal radio bearers；), and match somebody with somebody for UE
3 180900638 Put the related resources of E-DCH, such as E-RNTI.Now UE can reply RRC connection setup complete messages on e-dch, it is possible to be transmitted according to identical E-DCH transmitting procedures under CELL-DCH states.
Flow shown in Fig. 2 can be used for the transmission that CCCH is mapped on E-DCH, and it is consistent with the E-DCH transmitting procedures under CELL DCH states.UE does not have specific configuration information also during due to being transmitted on CCCH, thus some problems need solution：How UE E-RNTI is distributed, and how E-AGCH addresses some specific UE.A kind of simple mode is to broadcast several public E-RNTI by system broadcast message, and UE selections are one of as the E-RNTI of oneself, but this can cause E-RNTI conflict, i.e.,：There may be multiple UE while using same E-RNTI, cause Node B can not accurately address a specific UE, in turn result in the conflict of authorization resources.

The better embodiment of the present invention
The present invention is based on the random access algorithm in existing system.In existing TD-SCDMA (TD SDMAs）In system, E-RUCCH and traditional PRACH (Physical Random Access Channels）Random access channel resource in sharing system, 2 kinds of Stochastic accessings are made a distinction by synchronous code.Synchronous code in cell is divided into 2 groups, and one group is exclusively used in PRACH accesses；Another group is exclusively used in E-RUCCH accesses.System can configure a plurality of FPACH channels, and a FPACH channel is associated with a plurality of RACH.
UE is sent after the special synchronous codes of E-DCH, and a FPACH interception confirming information is selected according to following rule.
Rule one：The corresponding relation of uplink synchronous code and FPACH channel numbers is met：I=N mod M wherein N represent synchronous code numbering, M and represent the channel number that available FPACH total number of channels, i in the random access resource profile instance that UE is used represent selected FPACH.
Node B are detected after UE synchronous code, are sent and are confirmed to UE on FPACH channels, and Node B can only confirm a UE in a subframe on a FPACH channel, and FPACH selection is also obtained according to rule one.Relation between FPACH and E-RUCCH channels is met：
6 180900638 Rule two：The relation of FPACHi subframe numbers SFN' and PRACH channel number is met：（SFN'mod
LEi)=nE-RUccHi;
NE- UCCHi=0 ...,E-RUCCHi ~ 1 ;
Wherein NRUCCHlIt is the number of the E-RUCCH channel related to i-th of FPACH,
NE-RUCCH!No more than LEi;LEi is E-RUCCH transport block lengths, and general value is 1,2 (units：Subframe）；SFN' is the system subframe number when terminal receives confirmation on FPACHi, and mod is modular arithmetic.
UE is received after confirmation, and an E-RUCCH channel is selected according to rule two, and random accessing message is sent in second subframe after FPACH confirms is received.When E-RUCCH transport block lengths be more than 1 and second subframe subframe numbers be odd number when, then wait a subframe launch.
3GPP PHYs TS25.224 is specifically may be referred to above.The rule 2 that uses from above random access procedure is as can be seen that in a subframe, and a FPACH channel can only confirm UE access, thus will not occur resource contention in the E-RUCCH channel theorys associated with a FPACH channel, i.e.,：One E-RUCCH channel is only possible to be used by a UE in synchronization.
E-RNTI is set up and associated by the present invention with E-RUCCH channels, same public E-RNTI is also only possible to be used by a UE in the same time, so as to avoid public E-RNTI that the UE of more than 1 caused using same public E-RNTI conflict, as described in Figure 3, specially：
310, one or more public E-RNTI are distributed in cell, and it is associated with random access channel resource so that every one or more public E-RNTI of enhancing Stochastic accessing ascending control channel E-RUCCH correspondences;
Wherein, public E-RNTI resources are distributed by Node B；Public E-RNTI will be shared by the UE in cell.
Public E-RNTI and its broadcasted with the corresponding relation of E-RUCCH channels in system message；The corresponding public E-RNTI of each E-RUCCH is different on same carrier wave, on different carrier waves the corresponding public E-RNTI of each E-RUCCH can with it is identical, can also be different.
320, when UE, which have selected an E-RUCCH, initiates uplink random access, UE E-RNTI is filled in E-RUCCH, wherein the E-RNTI filled is the public E-RNTI associated with the E-RUCCH channels;
7 180900638 As an E-RUCCH channels multiple public E-RNTI of correspondence, UE have selected after an E-RUCCH, one in the multiple public E-RNTI that can be associated according to certain rule selection with the E-RUCCH, public E-RNTI selection rule can pass through protocol conventions, Ke Yiwei：
1) the UE mark of itself is passed through（ID) public E-RNTI is selected:Such as IMSI mod K=k, wherein IMSI (international mobile subscriber identity) are that UE ID, K are the public E-RNTI numbers with the E-RUCCH channels associateds, and k is exactly the sequence number for the public E-RNTI that UE is used；
2) E-RNTI, such as SFN'mod K=k, wherein SFN are selected according to current subframe numbers, is the subframe numbers that UE sends E-RUCCH（If E-RUCCH crosses over 2 subframes, then take the subframe numbers of the first subframe), K is the public E-RNTI numbers with the E-RUCCH channels associateds, and k is exactly the sequence number for the public E-RNTI that UE is used；
3) UE randomly chooses a public E-RNTI and is used as the E-RNTI of oneself.
330, Node B are received after the uplink random access that UE is sent by E-RUCCH, by E-AGCH to public E-RNTI user（Use public E-RNTI UE) resource authorization is carried out, wherein, there is the sequential relationship of determination between E-AGCH channels and UE E-RUCCH channels.
After public E-RNTI Conflict solvings, in addition it is also necessary to the problem of how E-AGCH channels address UE solved.The mandate when E-DCH that distribution 1 or a plurality of E-AGCH channels are used under CELL-FACH state in cell is transmitted, the one or more E-AGCH channels select one or more E-AGCH channels by Node B in cell E-AGCH resource pools, these channels can transmit shared resource with the E-DCH under CELL-DCH states, and be broadcasted by high level in system message.
When Node B are received after E-RUCCH to public E-RNTI user's authorization resources, E-AGCH channels address UE using public E-RNTI, and E-AGCH channels and the UE the last E-RUCCH sent have the sequential relationship of determination, the sequential relationship is indicated by high level configuration or protocol conventions or by E-AGCH channels.
The method that Node B address UE by E-AGCH channels is specifically included：
1) UE E-RNTI is included in the crc field of E-AGCH channels;
As E-DCH transmission is carried out under CELL-DCH states, when UE sends dispatch request on E-RUCCH channels, UE can take the E-RNTI of oneself, i.e. UE and be selected in public E-RNTI
8 180900638 E-RNTI.Node B can include UE E-RNTI information in CRC (CRC) field of E-AGCH channels.
2) there is the sequential relationship of determination between E-AGCH channels and UE E-RUCCH channels, UE recognizes whether E-AGCH channels are sent to oneself by the sequential relationship.
Due to E-RUCCH resources be in cell the UE time-divisions share, this also means that multiple UE can share a public E-RNTI time-division in cell, thus it can determine issue which UE's on earth by setting up sequential relationship between E-AGCH and E-RUCCH channels.Can be based on fixed sequential relationship between E-AGCH and E-RUCCH（Method 1) or flexible sequential relationship（Method 2).
Method 1：The sequential relationship between E-RUCCH dispatch requests is authorized by high level configuration or by protocol conventions E-AGCH, such as between the two every how many subframe or interval how many time slot.UE is after E-RUCCH channels are successfully sent, in defined sequential（I.e. high-rise configuration or the sequential of protocol conventions）Upper detection E-AGCH channels, if the E-AGCH channels include the E-RNTI selected by UE oneself, are taken as issuing oneself；If do not detected, illustrate that this authorized application does not succeed, UE can contemplate initiates dispatch request again.
Method 2:The dispatch request on the E-RUCCH which subframe is this sub-authorization is directed in is indicated on E-AGCH channels, UE is needed after dispatch request is initiated, send after E-RUCCH channels, continuous detection E-AGCH channels, if containing the E-RNTI of UE oneself selections on E-AGCH channels, in addition it is also necessary to judge whether it is one's own mandate according to persond eixis therein.
In order to avoid compatibility issue, persond eixis can utilize the EGSN fields on E-AGCH, certainly the invention is not restricted to carry out persond eixis using the field, under CELL-DCH states, the field is used to count the E-AGCH of same user and then carries out Power Control, and the field can't be used when CCCH is transmitted.The field is 3bits, and it is persond eixis that the present invention, which is reused, and for indicating that E-AGCH sends the interval between subframe and E-RUCCH transmission subframes, concrete mode can be：E-RUCCH sends numerical value-constant offset amount that the subframe numbers-EGSN where subframe numbers=E-AGCH is sent is indicated.
Constant offset amount can be by protocol conventions or high-rise configuration, and unit is subframe.Such as, constant offset amount is 7, current E-AGCH send where subframe numbers when to be 240, EGSN be 5, this sub-authorization pin
9 180900638 To E-RUCCH send subframe numbers be 228.That is, the E-AGCH channels will be received using the E-RNTI users for sending E-RUCCH in subframe numbers is 228.For UE, UE is after E-RUCCH is sent, start continuous monitoring E-AGCH channels after the number of sub-frames indicated by constant offset amount, if including the public E-RNTI of oneself selection on E-AGCH channels, and when sending the subframe numbers where subframe numbers are exactly oneself transmission E-RUCCH according to the E-RUCCH that persond eixis field is calculated, it is considered as the E-AGCH and is destined to oneself.It is the integer between 0-255 due to system subframe number, when being negative behind equation, 255 this offset should be added.
Incidence relation is set up by public E-RNTI and E-RUCCH and E-AGCH is set up and authorizes sequential relationship between E-RUCCH dispatch requests, can be solved when CCCH channels are mapped on E-DCH channels due to lacking specific configuration information the problem of can not address and address UE.
TD-SCDMA in current 3GPP system has been based on multicarrier framework.On the carrier wave for supporting E-DCH transmission, random access resource can be all set up（UpPCH, FPACH and E-RUCCH resource are sent including synchronous code）With E-DCH Traffic Channels E-PUCH and control channel（E-AGCH and E-HICH).Because the random access resource and E-DCH control channels of each carrier wave are all separate configurations, thus on different carrier waves, the associated public E-RNTI of E-RUCCH channels can be reused（I.e., it is possible to which configuration is identical）, and the associated public E-RNTI of each E-RUCCH channels should be different on same carrier wave.
Above is principle illustrates, illustrated below according to specific embodiment.
In this example, E-AGCH authorizes the sequential between E-RUCCH dispatch requests to be configured by high level.
High-rise to be mapped to information element required when on E-DCH firstly the need of configuration CCCH, information related to the present invention includes：
Public E-RNTI information and its incidence relation with E-RUCCH channels（As shown in table 1）, E-AGCH channels information（As shown in table 2).

Related to the present invention in table 1 is " public E-RNTI " information element and its information element of subordinate, can be the one E-RNTI list of every E-RUCCH channel configuration.Having one or more in each list, (number is represented with maxERNTIperERUCCH）The public public E-RNTI information of E-RNTL can be configured by Node B, and be organized in broadcast in system message by RNC.There is the information element that should have in most 16 random access resource profile instance, each profile instance shown in table 1 for main carrier in current system message；Configuration in secondary carrier is identical with the collocation method on main carrier.
The E-AGCH channel informations of table 2
E-AGCH channel resources are selected by Node B from the public E-AGCH resource pools of cell, and are broadcasted in system message after being organized by RNC.Te-agch is the time interval between E-RUCCH dispatch requests and E-AGCH mandates, and it reflects the dispatching and scheduling frequency of system, and the value can also be configured by RNC by Node B selections, finally also broadcasted in system message.If being selected by RNC, Te-agch needs to be allocated to Node B simultaneously.When allowing to carry out the E-DCH transmission under CELL FACH states in cell on multiple frequencies, the E-AGCH channel resources on multiple frequencies should be respectively configured.
11 180900638 UE is initiated before CCCH transmission, it is necessary to obtain above relevant information.
Fig. 4 is a specific CCCH data transmission procedure, the process based on premise be that cell supports CCCH to be mapped on E-DCH to transmit, and UE has E-DCH transmittabilities, specifically comprises the following steps：
401 :When UE needs to initiate RRC connections, UE selects a carrier wave, and selects to be exclusively used in the synchronous code of E-RUCCH accesses on the carrier wave, and the synchronous code is sent in available UpPCH subchannels；UE selects a FPACH channel according to rule one, is designated as FPACHi.
402:Node B are detected after synchronous code, and FPACHi channels are have selected by rule 1, and transmission confirms in the subframe for meeting rule 2.
403:UE is according to the selection of the rule 2 nth bar E-RUCCH channel associated with FPACHi.One public E-RNTI is selected according to system information, when this E-RUCCH is only associated with a public E-RNTI, UE uses the public E-RNTI;When this E-RUCCH is associated with multiple public E-RNTI, UE selects a public E-RNTI according to the rule of protocol conventions.Information in UE filling E-RUCCH channels, and take selected public E-RNTI.
404:Node B are received after E-RUCCH channels, and Node B send resource authorization information on wherein one article public E-AGCH channel in the Te-agch subframe after（Here can also be by the special E-RNTI of E-AGCH channel distributions), now UE can be received the E-AGCH channels for pointing to oneself selected E-RNTI by same sequential agreement.
405:UE detects E-AGCH channels in the Te-agch subframe after sending E-RUCCH, after E-AGCH channels contain E-RNTI (i.e. comprising E-RNTI public UE) for pointing to oneself, data are sent in the resource of mandate, it is to send the Initial R RC signalings being mapped on CCCH logic channels herein, UE can also carry schedule information in a data frame according to data volume situation.
406:Node B it is determined that timing slip on confirmed.
407:Node B are by the E-DCH data forwardings of reception to RNC.
Wherein, in step 405, if UE, which is not detected, points to the E-AGCH channels of oneself, this access failure is shown, UE needs initiating random access procedure again.
