Description
Technical field
The present invention relates to field of wireless communication, relate in particular under a kind of CELL_FACH (residential quarter _ forward access channel) state addressing and the addressing method of UE (user terminal) when E-DCH (enhanced-dedicated transmission channel) transmission CCCH (Common Control Channel).
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 E-DCH (enhanced-dedicated transmission channel) 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 efficiency of transmission.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-mapping 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, wherein the resource of non-scheduling service is that UE (user terminal) distributes by SRNC (service wireless network controller), the non-scheduling service resource has periodically and specificity, is suitable for real time business; In dispatching services, be that NodeB (Node B) distributes residential quarter enhanced uplink resource pool by SRNC, be single UE Resources allocation by Node B.
An E-DCH dispatching services transmission course under the CELL_DCH state as shown in Figure 1.
101:SRNC is through admitting control to think and can set up enhanced uplink for this UE, wireless link or wireless links reconfiguration course requirement Node B by NBAP (Node B Application Protocol, Node B application protocol) agreement are that UE sets up the E-PUCH Radio Link;
102: Node B receives configuration parameter, and being that from the up common pool of the enhancing of this residential quarter this UE distributes E-AGCH (enhancings-absolute grant channel) channel and E-RNTI (enhancings-Radio Network Temporary Identifier), the wireless link by NBAP responds or radio link reconfiguration responds and returns to SRNC;
103:SRNC is by RRC (Radio Resource Control, Radio Resource control) agreement is initiated radio bearer to UE and is set up order (radio bearer is set up request), wherein comprise the E-DCH configuration parameter, such 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 radio bearer and sets up request, obtains configuration parameter, replys radio bearer foundation to network side and finishes response message.UE determines that according to configuration parameter current E-DCH transport service is available; Become when non-zero by 0 when UE is mapped in the logic channel buffering area on the E-DCH data volume, UE initiates E-RUCCH (strengthens-accessing at random ascending control channel) random access procedure, accesses at random to comprise step 105-107:
105:UE selects to be exclusively used in the uplink synchronous code (SYNC_UL) that E-DCH accesses at random, sends by UpPCH (ascending pilot channel) channel;
After 106:Node B detects the uplink synchronous code of UE, send affirmation by FPACH (physical access channel) channel;
107:UE selects an E-RUCCH channel to send dispatch request (random access request) in the subframe of determining, wherein carries the E-RNTI of oneself;
108: after Node B detects the random access request of this UE, UE is added among the competition UE group who uses the E-DCH resource, according to current resource situation, the QoS of UE (Quality Of Service, service quality) attribute, UE auxiliary dispatching information etc. are dispatched this UE, after distributing suitable resource, send authorization message by the E-AGCH channel to UE, carry the E-RNTI of UE on the E-AGCH;
After 109:UE detects the E-AGCH that points to oneself, at timing n
E-AGCHAfter, UE sends data at the E-PUCH that authorizes, also have a control channel E-UCCH (enhancing-ascending control channel) who follows at E-PUCH, UE carries E-TFCI (indication of enhancing-transformat), HARQ (mixed automatic retransfer request) process number and re-transmission sequence number therein;
110: Node B is decoded to the control channel of following in the E-PUCH channel, obtain transport format information, then data portion is decoded, and returns ACK/NACK (confirming/retransmit) information at E-HICH (E-DCH HARQ confirms indicating channel) channel.
Up logic channel comprises CCCH (Common Control Channel), DCCH and DTCH under the CELL_FACH state.The RRC signaling that sends at the CCCH channel has:
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 (residential quarter-paging channel) and URA_PCH (UTRAN universal terrestrial access network Acceditation Area-paging channel) state initiates;
URA upgrades (URA Update): the UE of URA_PCH state initiates to upgrade.
When under the CELL_FACH state, carrying out the E-DCH transmission, because this state is not supported dedicated link, thereby can only carry out dispatching services, and Fig. 2 was mapped to a kind of rational flow process of E-DCH when upper with CCCH, and this flow process is consistent with initial E-DCH transmission course under the CELL_DCH state.
201-203: be in the Idle state or be in the UE of CELL_PCH, URA_PCH attitude, initiate up access, when namely sending RRC connection request or cell update request or URA and upgrade by the CCCH logic channel, at first carry out the uplink random access procedure.In this process, uplink synchronous code uses and is exclusively used in the synchronous code that E-DCH accesses at random, UE receives that Node B after the synchronous code that the FPACH channel is sent is confirmed, initiates at random access at the E-RUCCH channel that is associated, and wherein needs to carry the E-RNTI of schedule information and UE.
After 204:Node B detects the dispatch request of UE, by E-AGCH channel authorization resource, carry the E-RNTI of UE on the E-AGCH.
After 205:UE detects the E-RNTI that points to oneself, send data in the resource of authorizing, 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 at the timing slip of determining.
207:Node B with the E-DCH data retransmission that receives to RNC.
When the data of UE on CCCH do not transmit when finishing, Node B can continue to continue scheduling UE by the E-AGCH channel, and continues the process of above 204-207.
RNC can send response message after receiving the Initial R RC signaling of UE, such as the RRC connection request for UE, RNC can send the RRC connection and set up message.In this message, RNC can be the information (being mapped on the DCCH logic channel) of UE configuration signal radio bearer aspect, and for the relevant resource of UE configuring E-DCH, such as E-RNTI.This moment, UE can reply the RRC connection setup complete message at E-DCH, and can according to the CELL_DCH state under identical E-DCH transmission course transmit.
Flow process shown in Figure 2 can be used for CCCH and be mapped to transmission on the E-DCH, and it is consistent with E-DCH transmission course under the CELL_DCH state.Because UE does not also have specific configuration information during the upper transmission of CCCH, thereby some problems need to solve: how to distribute the E-RNTI of UE, E-AGCH is certain specific UE of addressing how.A kind of simple mode is to broadcast several public E-RNTI by system broadcast message, UE selects one of them as the E-RNTI of oneself, but this can cause the conflict of E-RNTI, that is: may there be a plurality of UE to use simultaneously same E-RNTI, cause accurately concrete UE of addressing of Node B, and then cause the conflict of authorization resources.

Embodiment
The present invention is based on the at random Access Algorithm in the existing system.In existing TD-SCDMA (TD SDMA) system, the random access channel resource in E-RUCCH and traditional PRACH (Physical Random Access Channel) sharing system, 2 kinds are accessed by synchronous code at random and distinguish.Synchronous code in the residential quarter is divided into 2 groups, and one group is exclusively used in the PRACH access; Another group is exclusively used in the E-RUCCH access.System can dispose many FPACH channels, and a FPACH channel is related with many Random Access Channel.
After UE sends the synchronous code of E-DCH special use, according to a FPACH interception confirming of following rules selection information.
Rule one: the corresponding relation of uplink synchronous code and FPACH channel number satisfies: i=N mod M
Wherein N represents the channel number that available FPACH total number of channels, i in the random access resource profile instance that synchronous code numbering, M represent the UE use represents 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.The relation of FPACH and E-RUCCH interchannel satisfies:
Rule two: the subframe numbers SFN ' of FPACHi and the relation of PRACH channel number satisfy: (SFN ' mod LEi)=n
E-RUCCHi
n
E-RUCCHi＝0，…，N
E-RUCCHi-1；
N wherein
E-RUCCHiThe number of the E-RUCCH channel relevant with i FPACH, N
E-RUCCHiBe not more than LEi; LEi is the E-RUCCH transport block length, and general value is 1,2 (units: subframe); SFN ' is the system subframe numbers of terminal when FPACHi receives affirmation, and mod is modular arithmetic.
After UE receives confirmation, select an E-RUCCH channel according to rule two, in second subframe receiving after FPACH confirms, send random accessing message.When the E-RUCCH transport block length is odd number greater than the subframe numbers of 1 and second subframe, wait for again subframe emission.
Below specifically can be with reference to 3GPP physical layer protocol TS25.224.Can find out from the rule 2 that above random access procedure uses, 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 occur, that is: an E-RUCCH channel only may be used by a UE at synchronization.
The present invention sets up related with the E-RUCCH channel E-RNTI, same public E-RNTI also only may be used by a UE at one time, thereby the conflict of the public E-RNTI that avoids UE more than 1 to use same public E-RNTI and cause as described in Figure 3, is specially:
310, in the residential quarter, distribute one or more public E-RNTI, and be associated with random access channel resource, so that every enhancing accesses the corresponding one or more public E-RNTI of ascending control channel E-RUCCH at random;
Wherein, public E-RNTI resource is distributed by Node B; Public E-RNTI will be shared by the UE in the residential quarter.
Public E-RNTI and in system message, broadcast with the corresponding relation of E-RUCCH channel;
The public E-RNTI that each E-RUCCH is corresponding on the same carrier wave is different, and the public E-RNTI that each E-RUCCH is corresponding on the different carrier can be identical, also can be different.
320, when UE has selected an E-RUCCH to initiate the uplink random access, in E-RUCCH, fill the E-RNTI of UE, the E-RNTI that wherein fills is the public E-RNTI that is associated with this E-RUCCH channel;
When the corresponding a plurality of public E-RNTI of an E-RUCCH channel, after UE has selected an E-RUCCH, can be according among certain rules selection a plurality of public E-RNTI related with this E-RUCCH, the selective rule of public E-RNTI can be arranged by agreement, can for:
1) selects public E-RNTI by self the sign (ID) of UE: such as IMSI mod K=k, wherein IMSI (international mobile subscriber identity) is that ID, the K of UE are and the public E-RNTI number of this E-RUCCH channels associated, and k is exactly the sequence number of the public E-RNTI of UE use;
2) select E-RNTI according to current subframe numbers, such as SFN ' mod K=k, wherein SFN ' is subframe numbers (if 2 subframes of E-RUCCH leap that UE sends E-RUCCH, get so the subframe numbers of the first subframe), K is and the public E-RNTI number of this E-RUCCH channels associated that k is exactly the sequence number of the public E-RNTI of UE use;
3) UE selects a public E-RNTI as the E-RNTI of oneself at random.
330, after Node B receives the uplink random access of UE by the E-RUCCH transmission, carry out resource authorization by E-AGCH to public E-RNTI user (namely using the UE of public E-RNTI), wherein, the E-RUCCH interchannel of E-AGCH channel and UE has definite sequential relationship.
After public E-RNTI conflict solves, also need to solve the how problem of addressing UE of E-AGCH channel.Mandate when 1 or many E-AGCH channels of distribution are for the transmission of the E-DCH under the CELL_FACH state in the residential quarter, this one or more E-AGCH channel is selected one or more E-AGCH channels by Node B in the E-AGCH resource pool of residential quarter, these channels can with the CELL_DCH state under E-DCH transmission shared resource, and broadcasted in system message by high level.
When Node B receives the backward public E-RNTI subscriber authorisation resource of E-RUCCH, the E-AGCH channel uses public E-RNTI addressing UE, and the E-RUCCH that the last time of E-AGCH channel and this UE sends has definite sequential relationship, and this sequential relationship is by high level configuration or agreement agreement or pass through the indication of E-AGCH channel.
Node B specifically comprises by the method for E-AGCH channel addressing UE:
1) comprises the E-RNTI of UE in the crc field of E-AGCH channel;
The same as carrying out E-DCH transmission under the CELL_DCH state, as UE during in E-RUCCH channel transmission dispatch request, UE can be with upper oneself E-RNTI, i.e. the E-RNTI that selects in public E-RNTI of UE.Node B can comprise the E-RNTI information of UE in the CRC of E-AGCH channel (cyclic redundancy check (CRC)) field.
2) the E-RUCCH interchannel of E-AGCH channel and UE has definite sequential relationship, and UE identifies the E-AGCH channel by this sequential relationship and whether is sent to oneself.
Since the E-RUCCH resource be the residential quarter in the UE time-division share, this means that also a plurality of UE understand shared public E-RNTI of time-divisions the residential quarter in, thereby can set up sequential relationship by E-AGCH and E-RUCCH interchannel and determine to issue on earth which UE's.Can be based on fixing sequential relationship (method 1) or sequential relationship (method 2) flexibly between E-AGCH and the E-RUCCH.
Method 1: by high level configuration or by agreement agreement E-AGCH authorize and the E-RUCCH dispatch request between sequential relationship, such as between the two every how many subframes or how many time slots of interval.UE at sequential (i.e. the sequential of high-rise configuration or agreement agreement) the detection E-AGCH channel of regulation, if this E-AGCH channel comprises the selected E-RNTI of UE oneself, just thinks to issue oneself after successfully sending the E-RUCCH channel; If do not detect, not success of this authorized application then is described, UE can consider again to initiate dispatch request.
Method 2: this is authorized for the dispatch request on the E-RUCCH in which subframe in the indication of E-AGCH channel, UE need to be after initiating dispatch request, after namely sending the E-RUCCH channel, continuous detecting E-AGCH channel, if comprised the E-RNTI that UE oneself selects on the E-AGCH channel, also need basis persond eixis wherein to judge whether it is one's own mandate.
For fear of compatibility issue, persond eixis can utilize the EGSN field on the E-AGCH, certainly the invention is not restricted to use this field to carry out persond eixis, under the CELL_DCH state, this field is counted for the E-AGCH to same user and then is carried out power control, can't use this field when CCCH transmits.This field is 3bits, and the present invention reuses it and is persond eixis, be used to indicate E-AGCH and send subframe and E-RUCCH and send interval between the subframe, concrete mode can for:
The numerical value of the subframe numbers at E-RUCCH transmission subframe numbers=E-AGCH transmission place-EGSN indication-constant offset amount.
The constant offset amount can be by agreement agreement or high-rise configuration, and unit is subframe.Such as, the constant offset amount is 7, the subframe numbers that current E-AGCH sends the place is that 240, EGSN is 5 o'clock, this authorize for E-RUCCH to send subframe numbers be 228.That is be that the user who uses this E-RNTI to send E-RUCCH in 228 will receive this E-AGCH channel at subframe numbers.For UE, UE is after sending E-RUCCH, the E-AGCH channel is monitored in beginning continuously after the indicated number of sub-frames of constant offset amount, if comprise the public E-RNTI that oneself selects on the E-AGCH channel, and sending subframe numbers according to the E-RUCCH that the persond eixis field calculates is exactly when oneself sending the subframe numbers at E-RUCCH place, just to think that this E-AGCH sends to oneself.Because system's subframe numbers is the integer between the 0-255, when the equation back is negative, should add 255 these side-play amounts.
By public E-RNTI and E-RUCCH set up incidence relation and set up that E-AGCH authorizes and the E-RUCCH dispatch request between sequential relationship, can solve the CCCH channel mapping and can't address problem with addressing UE to the E-DCH channel the time owing to lack specific configuration information.
TD-SCDMA in the 3GPP system is based on the multicarrier framework at present.Support on the carrier wave of E-DCH transmission, all can set up random access resource (comprising that synchronous code sends UpPCH, FPACH and E-RUCCH resource) and E-DCH Traffic Channel E-PUCH and control channel (E-AGCH and E-HICH).Because random access resource and the E-DCH control channel of each carrier wave all are separate configurations, thereby the public E-RNTI that the E-RUCCH channel is associated on the different carrier can reuse (namely, that can dispose is identical), and the public E-RNTI that each E-RUCCH channel is associated on the same carrier wave should be different.
More than be the principle explanation, the below describes according to specific embodiment.
In this example, the sequential between E-AGCH mandate and the E-RUCCH dispatch request is disposed by high level.
High-rise at first need to dispose CCCH and be mapped to E-DCH required information element when upper, information related to the present invention comprises:
Public E-RNTI information and with the incidence relation (as shown in table 1) of E-RUCCH channel, the information (as shown in table 2) of E-AGCH channel.
The public E-RNTI of table 1 and E-RUCCH channels associated relation
Related to the present invention in the table 1 is " public E-RNTI " information element and subordinate's thereof information element, can be E-RNTI tabulation of every E-RUCCH channel configuration.In each tabulation public E-RNTI of one or more (number represent with maxERNTIperERUCCH) is arranged.Public E-RNTI information can be by Node B configuration, and is organized in the system message by RNC and broadcasts.For main carrier maximum 16 random access resource profile instance are arranged in the system message at present, should have the information element shown in the table 1 in each profile instance; Configuration on the auxiliary carrier wave is identical with collocation method on the main carrier.
Table 2E-AGCH channel information
The E-AGCH channel resource is selected from the public E-AGCH resource pool in residential quarter by Node B, and by in system message, broadcasting behind the RNC tissue.Te-agch is the time interval between E-RUCCH dispatch request and E-AGCH authorize, and it has reflected dispatching and the scheduling frequency of system, and this value can be selected also can be disposed by RNC by Node B, finally also broadcasts in system message.If selected by RNC, Te-agch need to dispose simultaneously to Node B.When the E-DCH transmission that allows on a plurality of frequencies in the residential quarter to carry out under the CELL_FACH state, should dispose respectively the E-AGCH channel resource on a plurality of frequencies.
UE need to 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 residential quarter supports CCCH to be mapped to the upper transmission of E-DCH, and UE has the E-DCH transmittability, specifically comprises following steps:
When 401:UE need to initiate the RRC connection, UE selected a carrier wave, and selected to be exclusively used on this carrier wave the synchronous code of E-RUCCH access, sent this synchronous code at available UpPCH subchannel; UE selects a FPACH channel according to rule one, is designated as FPACHi.
After 402:Node B detects synchronous code, select the FPACHi channel by rule 1, and sent affirmation in the subframe that satisfies rule 2.
The n bar E-RUCCH channel that 403:UE is associated with FPACHi according to rule 2 selections.Select a public E-RNTI according to system information, when this E-RUCCH was only related with a public E-RNTI, UE used this public E-RNTI; When this E-RUCCH was related with a plurality of public E-RNTI, UE was according to public E-RNTI of rules selection of agreement agreement.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, Node B after Te-agch subframe on wherein public E-AGCH channel send resource authorization information (here also can by the E-RNTI of E-AGCH channel allocation special use), this moment, UE can receive the E-AGCH channel that points to own selected E-RNTI by same sequential agreement.
Te-agch the subframe of 405:UE after sending E-RUCCH detects the E-AGCH channel, contain the E-RNTI (namely comprising the public E-RNTI of UE) of sensing oneself when the E-AGCH channel after, send data in the resource of authorizing, 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 at the timing slip of determining.
407:Node B with the E-DCH data retransmission that receives to RNC.
Wherein, in the step 405, if UE does not detect the E-AGCH channel that points to oneself, show this access failure, UE needs again initiating random access procedure.
Industrial applicibility
The present invention utilizes the relation of each interchannel in the at random Access Algorithm in the existing system to design addressing method, make public E-RNTI and E-RUCCH channel bind mutually, make E-AGCH mandate and E-RUCCH channel to set up sequential relationship, can reach like this a user's of unique identification purpose.The present invention is based on existing random access procedure and E-DCH transfer process, simply available.
