Description
Technical field
The present invention relates to field of wireless communication, relate in particular to the method for initial access under a kind of CELL_FACH (sub-district _ forward access channel) state and the transmission method of initial access signaling.
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 state makes it obtain less packet transfer delay and higher transmission rate through introducing the ascending packet data transmission performance that E-DCH (enhancing-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).The physical-layer techniques of HSUPA uses advanced obtains high-transmission efficient.In the version before the 3GPP Rel-7; The E-DCH transmission is only used under CELL_DCH (cell private channel) state; Signaling or data on DCCH (DCCH) or DTCH (Dedicated Traffic Channel) logic channel are mapped to earlier on the E-DCH transmission channel, are mapped on E-PUCH (enhancing-physical uplink channel) physical channel from 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 (subscriber equipment) distributes by SRNC (service wireless network controller), and resource has periodically and specificity, is suitable for real time business; In dispatching services, be that NodeB (Node B, i.e. base station) distributes sub-district enhanced uplink resource pool by SRNC, be single UE Resources allocation by Node B again.
An E-DCH dispatching services transmission course under the CELL_DCH state is as shown in Figure 1, may further comprise the steps:
101:SRNC thinks to be that UE sets up the E-PUCH Radio Link through the Radio Link foundation request or the radio link reconfiguration request requirement Node B of sending NBAP (node B application part) agreement then for this UE sets up enhanced uplink through admittance control;
102: after Node B receives configuration parameter; Be this UE distribution E-AGCH (enhancing-absolute grant channel) channel and E-RNTI (enhancing-Radio Link temporary mark) from the enhanced uplink common pool of this sub-district, and it returned to SRNC through Radio Link foundation response or the radio link reconfiguration response of NBAP;
103:SRNC initiates radio bearer through RRC (Radio Resource control) agreement to UE and sets up request; Wherein comprise the E-DCH configuration parameter, like 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 configuration parameter, replys radio bearer to network side and sets up completion message.Confirm that according to configuration parameter current E-DCH transport service is available; UE is mapped to that data volume becomes at non-0 o'clock by 0 in the logic channel buffering area on the E-DCH, and UE initiates enhanced random and inserts request, promptly initiates access at random through E-RUCCH (strengthens-inserting ascending control channel at random) channel and asks, and 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 to Node B through UpPCH (ascending pilot channel) channel;
After 106:Node B detects the uplink synchronous code of UE, send affirmation through FPACH (physical access channel) channel;
107:UE selects an E-RUCCH channel on the subframe of confirming, to send enhanced random and inserts request, wherein carries schedule information and the E-RNTI of oneself;
108: Node B adds UE among the competition UE crowd who uses the E-DCH resource after detecting the enhanced random access request of this UE.Node B is dispatched this UE according to QOS (service quality) attribute of current resource situation, UE, UE auxiliary dispatching information etc., after distributing adequate resources for it, sends authorization message through the E-AGCH channel to UE, the last E-RNTI that carries UE of E-AGCH;
After 109:UE detects the E-AGCH that points to oneself, after arriving timing nE-AGCH, on the E-PUCH that authorizes, send data.The last control channel E-UCCH (enhancing-ascending control channel) who follows in addition of E-PUCH, UE carries E-TFCI (indication of enhancing-transformat), HARQ (mixing automatic repeat requests) process number and re-transmission sequence number therein;
110: Node B is decoded to the control channel of following in the E-PUCH channel, obtains transport format information, and data portion is decoded then, and on the E-HICH channel, returns ACK/NACK information.
Under the CELL_FACH state, do not have private processes between Node B and the SRNC, thereby 101 and 102 flow processs do not exist among Fig. 1, the transfer process of E-DCH and transmission course consistent (105 to 110) under the CELL_DCH state.Up logic channel comprises CCCH (CCCH), DCCH and DTCH under the CELL_FACH state.UE sends the CCCH channel during initial the access, and the RRC of transmission (Radio Resource control) initial access signaling comprises:
RRC connection request (RRC Connection Request): be in the link setup message that the UE under free time (Idle) state initiates;
Cell update (Cell Update): be in the initial access message that the UE under the connection status initiates when arriving new sub-district after the district reselecting;
URA upgrades (UTRAN Registration Area Update, the Universal Terrestrial Radio Access Network Acceditation Area upgrades): the initial access message of initiating when being in UE URA_PCH (URA_ physical channel) state under through the new registration area of arrival after the district reselecting.
During initial the access, UE has no specific configuration information, and promptly 103 among Fig. 1 and 104 also do not exist.After initial access signaling such as having only to send to network side, UE just possibly receive configuration signal.Just because of this, also have some problems to need to solve when on E-DCH, carrying out the initial access signaling transmission: as because UE this moment does not have special-purpose E-RNTI, how to send authorization resources information, promptly how to use problems such as E-AGCH channel addressing UE to UE.
A kind of available method is following: for UE distributes public E-RNTI, be used for the initial access signaling transmission, and public E-RNTI and E-RUCCH channel are set up incidence relation.Because the E-RUCCH channel can only be used by a UE at same TTI (Transmission Time Interval); Thereby same public E-RNTI also only possibly use by a UE at one time, therefore avoided the UE more than 1 to use same public E-RNTI simultaneously and the conflict of the public E-RNTI that causes.
After public E-RNTI conflict solves, also need solve the how problem of addressing UE of E-AGCH channel.1 or many E-AGCH channels of distribution are used for the E-DCH transmission under the CELL_FACH state in the sub-district; This one or more E-AGCH channel is selected in the E-AGCH resource pool of sub-district by Node B; These channels can transmit shared resource with the E-DCH under the CELL_DCH state, and are broadcasted in system message by high level.
Node B receives behind the E-RUCCH when using the UE authorization resources of public E-RNTI; The E-AGCH channel uses this public E-RNTI addressing UE; And the last E-RUCCH place time slot of E-AGCH channel place time slot and this UE use has definite sequential relationship, and this sequential relationship is arranged by high level configuration, agreement or indicated through the E-AGCH channel.
Through following two aspects, Node B can be addressed to a concrete UE:
1) comprises the E-RNTI of UE in the crc field of E-AGCH channel;
With under the CELL_DCH state, to carry out E-DCH transmission the same, insert at random when asking when UE sends on the E-RUCCH channel, except carrying schedule information, UE also can with on oneself E-RNTI.Node B can comprise the E-RNTI information of UE in the CRC of E-AGCH channel (CRC) field.The initial access signaling transmit stage, the E-RNTI that UE sends is the E-RNTI with selected E-RUCCH channels associated.
2) the last E-RUCCH interchannel of E-AGCH channel and UE use has definite sequential relationship, and whether UE discerns the E-AGCH channel through this sequential relationship and send out to oneself.Because public E-RNTI can be shared by the UE timesharing in the sub-district, thereby after setting up the sequential relationship of E-AGCH channel and E-RUCCH channel, Node B just can be addressed to a concrete UE.
When more than having solved UE and being in the initial access signaling transmit stage, send insert request at random after, Node B is the problem of addressing UE how.According to above method, after Node B received an E-RUCCH, if the E-RNTI that wherein carries is public E-RNTI, what Node B just can judge that UE need carry out so was the initial access signaling transmission.
The up enhancing of CELL_FACH is based on RLC PDU (wireless link control protocol data cell) length flexibly, and supports the segmentation of MAC (medium access control) layer, and UE accomplishes the transmission of E-DCH packet with new entity MAC-i/is.Thereby when initial access signaling is mapped to E-DCH and goes up transmission, need to consider a kind of situation, be exactly that signaling possibly be divided into the transmission of a plurality of MAC-i bag.In this case, if the not enough UE of the resource that Node B once authorizes accomplishes the transmission of all MAC-i bags, so follow-up mandate just can't be sent down, and UE can only initiate new access at random again with the application resource, and this will bring bigger time delay.

Embodiment
To combine accompanying drawing and embodiment that technical scheme of the present invention is explained in more detail below.
The transmission method of initial access signaling under a kind of CELL_FACH state may further comprise the steps:
A, subscriber equipment send enhanced random to Node B and insert request, carry wherein that to be used to indicate data to be transferred be the indication information of initial access signaling and the data amount information of this data to be transferred;
B, Node B are as judging that according to above-mentioned indication information above-mentioned data to be transferred is an initial access signaling, and then utilizing above-mentioned data amount information and maximum retransmission is the resource that above-mentioned data to be transferred is enough transmitted in above-mentioned subscriber equipment mandate; Wherein, maximum retransmission is by the high-rise HARQ number of retransmissions that disposes to the signaling transmission feature of CCCH channel of network;
C, above-mentioned subscriber equipment transmit above-mentioned data to be transferred on above-mentioned authorization resources.
Wherein, among the step a, it is initial access signaling that above-mentioned subscriber equipment can be indicated above-mentioned data to be transferred through the public E-RNTI that in above-mentioned enhanced random access request, carries its selection; Also can carry particular value that a UE and Node B appointed to indicate above-mentioned data to be transferred be initial access signaling through insert highest priority logical channel signaling amount parameter to be passed or highest priority logical channel parameter in the schedule information of carrying in the request in enhanced random.Can also carry the data amount information of above-mentioned initial access signaling through the buffer state parameter in the schedule information in the above-mentioned enhanced random access request.
The initial down method that inserts of a kind of CELL_FACH state, as shown in Figure 2, may further comprise the steps:
201, user equipment (UE) sends enhanced random to Node B and inserts request, carries wherein that to be used to indicate data to be transferred be the indication information of initial access signaling and the data amount information of above-mentioned data to be transferred;
202, Node B is as judging that according to above-mentioned indication information above-mentioned data to be transferred is an initial access signaling, and then utilizing above-mentioned data amount information and maximum retransmission is that above-mentioned UE authorizes enough resources of the above-mentioned data to be transferred of transmission; Wherein, maximum retransmission is by the high-rise HARQ number of retransmissions that is configured to the signaling transmission feature of CCCH channel of network;
203, UE transmits said data to be transferred on above-mentioned authorization resources, if when above-mentioned resource authorization expires, accomplished the transmission of above-mentioned data to be transferred, then UE initially inserts success; Otherwise, the initial access failure of UE.
If in step 203, UE still has remaining authorization resources not to be used after the transmission of accomplishing above-mentioned data to be transferred, and then it sends a transfer of data to Node B and accomplishes indication information on the Transmission Time Interval of next one mandate; After Node B is received, regain remaining authorization resources.
Can also be in step 203; If UE is when last packet of transmission; Transmission Time Interval and remaining space that the data volume of this packet is not enough to fill up a mandate are enough to transmit a transfer of data and accomplish indication information, and then UE together sends to Node B with last packet and transfer of data completion indication information; After Node B is received, regain remaining authorization resources.
In above-mentioned two kinds of situation, it can be that 0 schedule information or other can be represented the indication information that transfer of data is accomplished for a buffer state parameter value that transfer of data is accomplished indication information.
Wherein, in the step 201, subscriber equipment can carry its public E-RNTI to indicate data to be transferred be initial access signaling through inserting in enhanced random in the request; Also can carry particular value that a UE and Node B appointed to indicate above-mentioned data to be transferred be initial access signaling through insert highest priority logical channel signaling amount parameter to be passed or highest priority logical channel parameter in the schedule information in the request in enhanced random.Can also carry the data amount information of data to be transferred through the buffer state parameter in the schedule information in the enhanced random access request.
Further specify the present invention through an instantiation of the present invention below.
When on E-DCH, carrying out the transmission of initial access signaling, UE is in a kind of in following three kinds of states:
State one: UE is in idle condition, initiates RRC and connects;
State two: UE is in CELL_DCH, CELL_FACH or CELL_PCH (sub-district physical channel), district reselecting has taken place arrived a new sub-district, initiates cell update;
State three: UE is in the URA_PCH state, and district reselecting has taken place, and new sub-district is positioned at a new URA district, and UE initiates URA and upgrades.
When UE need transmit initial access signaling, it carried out the enhanced random access, sent enhanced random through the E-RUCCH channel and inserted request, and it is as shown in table 1 that E-RUCCH goes up parameter entrained in the enhanced random access request in the existing system:
Table 1E-RUCCH goes up information transmitted
| This sub-district, adjacent sub-district path loss (5 bit) | Power headroom (5 bit) | Buffer state (5 bit) | Highest priority logical channel signaling amount to be passed (4 bit) | Highest priority logical channel number (4 bit) | UE identifies (16 bit) |
Wherein, preceding 5 fields are exactly schedule information." buffer state " wherein filled in the data volume of the initial access signaling on the CCCH channel; Because UE this moment has only the CCCH channel to need transmission; Thereby " highest priority logical channel signaling amount to be passed ", " highest priority logical channel number " can be filled in not according to existing method; Can carry other content, as representing that data to be transferred is an initial access signaling through carrying a particular value " 0000 "; " this sub-district, adjacent sub-district path loss ", " power headroom " filled in by existing mode.Last field " UE sign " is filled in the public E-RNTI that UE selects.
Use because public E-RNTI only carries out initial access signaling when transmission at UE, thereby when Node B receives E-RUCCH after, if " UE sign " field carries is public E-RNTI, NodeB just thinks that UE need carry out initial access signaling and transmit so.Certainly, also can exist alternate manner to indicate initialization signaling transmission, indicating data to be transferred such as " the highest priority logical channel signaling amount to be passed " mentioned in above utilizing, " highest priority logical channel number " is initial access signaling.
Because in the initial access signaling transmit stage, UE does not have special-purpose E-RNTI, can't repeatedly authorize.Therefore in the present invention, Node B can accomplish the required whole resources of initial access signaling transmission to the UE primary distribution of carrying out the initial access signaling transmission.
The buffer state that UE reports has been confirmed the resource sum that UE is required with the number of retransmissions of high-rise configuration, also need consider the signaling consumption of MAC layer certainly.When the actual allocated resource; Node B need come comprehensively to carry out concrete resource allocation according to the factors such as situation of the schedule information of UE, the RRM of Node B (Radio Resource control) algorithm, available resources, comprises the number of the TTI that the authorization power of confirming each TTI and channel resource are big or small and required.
Each information field to the influence of resource allocation is in the schedule information:
1, UE " this sub-district, the adjacent sub-district path loss " and " power headroom " that the report size that influences the power mandate of UE;
2, " buffer state ", the size that " this sub-district, adjacent sub-district path loss " and " power headroom " influences a TTI channel resource that report of UE;
After having confirmed the power mandate and channel resource mandate of a TTI, Node B utilizes " buffer state " and " number of retransmissions " also to need what TTI to accomplish transmission with regard to the data of having confirmed UE, and method is following:
1. confirm the length of the maximum MAC-i packet that can transmit in a TTI (hereinafter to be referred as the MAC bag) according to power mandate and channel resource mandate, this process is consistent with E-TFC (enhancing-transformat combination) selection course in the existing system;
2. then, need just can confirm what MAC packets could accomplish the initial access signaling transmission, thereby confirm to accomplish the required resource size (unit: the TTI number) of signaling transmission one time according to " buffer state " that UE reports;
3. last, can confirm final resource size (unit: the TTI number) according to the maximum retransmission of CCCH channel data bag.
Concrete resource authorization process depends on the inside realization of Node B, and this is an iteration trade-off process between the multiple factors such as a data volume request at UE, area interference control, cell available resources.Such as, TTI number excessive (above 8) can influence uplink synchronous control and the power control of UE, and this moment, Node B considered strengthened the authorization resources of single TTI, thereby dwindled the length of TTI.Such as a RRC connection request message-length is 25 bytes (200 bits); Power mandate and the channel resource mandate of supposing Node B allows UE to transmit the data of 162 bits at a TTI, and UE needs 2 MAC bags just maybe this signaling be transmitted to accomplish (wherein also need consider the signaling consumption of MAC layer) so; If the maximum retransmission of the CCCH channel of high-rise configuration is 1, accomplish a RRC connection request message in order to transmit so, UE will send 4 MAC bags at most, and Node B need distribute the resource of 4 TTI to give UE.
In the prior art; The E-AGCH channel can pass through the resource of RDI (Resource Duration Indicator, resource continuous indication) a plurality of TTI of field privilege, maximum 8; As shown in table 2, Node B can utilize this mechanism to accomplish the mandate of initial access signaling transmission.According to last example, Node B can have three kinds of selections, is respectively RDI=4,5,6.
Table 2 resource allocation dial gauge
| RDI (3 bit) | The TTI number of distributing | TTI at interval |
| 0 | 1 | 1 |
| 1 | 2 | 1 |
| 2 | 2 | 2 |
| 3 | 2 | 4 |
| 4 | 4 | 1 |
| 5 | 4 | 2 |
| 6 | 4 | 4 |
| 7 | 8 | 1 |
According to the method in the background information, after UE sends E-RUCCH, on the sequential of confirming, receive the mandate of pointing to own selected public E-RNTI, on authorization resources, transmit the back at interval in the agreement predetermined timing then.After UE accomplishes first MAC bag transmission, on the TTI of ensuing all authorization resources, can retransmit, also can transmit new MAC bag according to the feedback that head passes packet.
If before resource authorization is overtime, accomplished the transmission of initial access signaling, the initial of UE inserted successfully, has 2 kinds of situation this moment:
1, the authorization resources of UE just in time uses up;
2, UE also has the authorization resources of unnecessary TTI.
To first kind of situation, Node B passes to RNC with the successful MAC packet that receives through Iub mouth user plane, sends to upper layer entity after being sorted by RNC, and this moment, UE waited for the response message of network side to initial access.
The reason of second kind of situation appearance has 2 kinds:
1, the re-transmission of packet does not reach maximum retransmission;
The scope of the corresponding data volume of " buffering area " state that 2, UE reports in the existing protocol be not accurate buffer area data volume size, thereby authorization resources has error with actual data volume size.
In order effectively to utilize system resource; It is said that UE can be through in the end carrying the indication that a number is totally lost in a MAC packet; Such as carrying a schedule information; Wherein indication " buffer state " is 0, makes Node B can know that UE has accomplished transfer of data, residual resource is regained be used for other user.When the expiration of the authorization resources of UE, after the data of perhaps receiving UE were accomplished indication, the MAC of this UE that Node B can success receives wrapped and be transmitted to RNC.
If when said resource authorization is overtime, do not accomplish the transmission of initial access signaling, the initial access failure of UE, UE will be initiated the new request of access at random again.After new access was at random accomplished, UE resend initial access signaling.
A concrete initial access signaling transmission course is as shown in Figure 3, and wherein UE initiates the RRC connection request from idle condition.
When 301:UE need initiate the RRC connection, select a carrier wave, and select to be exclusively used in the synchronous code that E-RUCCH inserts on this carrier wave, on available UpPCH subchannel, send this synchronous code; UE selects a FPACH channel according to the rule of existing protocol agreement;
After 302:Node B detects synchronous code, select a FPACH channel, and on corresponding subframe, send and confirm by same rule;
After 303:UE receives affirmation; The E-RUCCH channel that selection is associated with FPACH; And selecting the public E-RNTI be associated with this E-RUCCH, UE fills the information in the E-RUCCH channel, comprises that the metrical information of basis oneself is filled in this sub-district, adjacent sub-district path loss, power headroom; Size according to the corresponding RLC PDU of RRC connection request is filled in " buffer state "; In the UE identification field, fill in selected public E-RNTI;
After 304:Node B receives the E-RUCCH channel; After the Te-agch sub-frame send authorization message through the E-AGCH channel; The enough UE of this authorization resources have sent initial access signaling, in this example, suppose that initial access signaling needs the resource of 4 TTI at most.Consider that there are certain time delay (general E-HICH confirms the next subframe in the E-PUCH transmission) in E-HICH affirmation and E-PUCH between sending; Thereby to needing certain interval between the TTI of UE mandate; So just can make UE before next authorization resources TTI arrives; Obtain the affirmation information of a packet, can accomplish the re-transmission of packet to the packet that does not have successfully to send as early as possible.Thereby suggestion RDI is set to 5, i.e. the TTI at each an authorization resources place sub-frame at interval.
Detect the E-AGCH channel on the Te-agch sub-frame of 305:UE after sending E-RUCCH, after containing the E-RNTI that points to oneself, on the resource of authorizing, send data, be to send to be mapped to the Initial R RC signaling on the CCCH logic channel here.
306:Node B confirms on the timing slip of confirming.
UE is in the transmission and the repeating transmission of the enterprising line data bag of follow-up authorization resources.In the end in new data packets; If 23 bit space of residue are arranged, UE will be used to fill an enhanced random and insert request, and wherein indicating buffer state is 0; After Node B receives, judge and to regain resource after all data retransmissions in should the HARQ entity of UE are all successfully received.If UE has successfully transmitted all packets; And also do not accomplish (not having unnecessary space transmitting scheduling information) to Node B indication transmission; If also have remaining TTI resource this moment, UE can authorize at the next one and send a schedule information on the TTI, and the indication buffer state is 0.
307:Node B gives RNC with the MAC data forwarding that receives after confirming that UE accomplishes the initial access signaling transmission.Node B confirms that UE accomplishes the method for transfer of data: resource has used up or has received the schedule information of UE, and wherein indicating buffer state is 0.
Discussion of the present invention be initial access signaling, initial access signaling all uses the CCCH Channel Transmission.On the CCCH channel, only transmit following signaling:
RRC connection request (RRC Connection Request);
Cell update (Cell Update);
URA upgrades (UTRAN Registration Area Update, the Universal Terrestrial Radio Access Network Acceditation Area upgrades).
But the transmission of CCCH is not equal to the transmission of initial access signaling.Because cell update and URA upgrade the situation that UE periodically updates that also can be used in the sub-district, this moment, UE had the E-RNTI of oneself.When actual formulating standard,, may require the transmission of CCCH all to use the method for the invention in order to simplify and to make things convenient for.Like this, thought of the present invention can expand to the transmission of all CCCH channels.The present invention also has a specific embodiment, is exactly the situation that CCCH goes up transmission, may further comprise the steps:
When 401:UE need initiate the CCCH transmission, select a carrier wave, and select to be exclusively used in the synchronous code that E-RUCCH inserts on this carrier wave, on available UpPCH subchannel, send this synchronous code; UE selects a FPACH channel according to the rule of existing protocol agreement;
After 402:Node B detects synchronous code, select a FPACH channel, and on corresponding subframe, send and confirm by same rule;
After 403:UE receives affirmation; The E-RUCCH channel that selection is associated with FPACH; And selecting the public E-RNTI be associated with this E-RUCCH, UE fills the information in the E-RUCCH channel, comprises that the metrical information of basis oneself is filled in this sub-district, adjacent sub-district path loss, power headroom; Size according to the corresponding RLC PDU of CCCH channel signaling to be passed is filled in " buffer state "; In the UE identification field, fill in selected public E-RNTI, be i.e. all use public E-RNTI during CCCH transmission; The method of another kind of indication CCCH transmission is that " highest priority logical channel number " used a specific logical channel number that is exclusively used in CCCH; Such as " 0000 "; The E-RNTI field of this moment can be filled in according to UE actual allocated situation; When UE is assigned E-RNTI, fill in the E-RNTI of UE self; Otherwise fill in public E-RNTI;
After 404:Node B receives the E-RUCCH channel, if public E-RNTI user, then after the Te-agch sub-frame send authorization message through the E-AGCH channel; If special-purpose E-RNIT user, Node B can not limit and send the time point of authorizing so.The enough UE of this authorization resources have sent this CCCH signaling, in this example, suppose that the CCCH signaling needs the resource of 4 TTI at most.Consider that there are certain time delay (general E-HICH confirms the next subframe in the E-PUCH transmission) in E-HICH affirmation and E-PUCH between sending; Thereby to needing certain interval between the TTI of UE mandate; So just can make UE before next authorization resources TTI arrives; Obtain the affirmation information of a packet, can accomplish the re-transmission of packet to the packet that does not have successfully to send as early as possible.Thereby suggestion RDI is set to 5, i.e. the TTI at each an authorization resources place sub-frame at interval.
405: to detecting the E-AGCH channel on the Te-agch sub-frame of UE after sending E-RUCCH of using public E-RNTI user; User to using special E-RNTI need detect the E-AGCH channel constantly.Behind the E-AGCH that contains the E-RNTI that points to oneself, on the resource of authorizing, send data, be to send to be mapped to the RRC signaling on the CCCH logic channel here.
406:Node B confirms on the timing slip of confirming.
UE is in the transmission and the repeating transmission of the enterprising line data bag of follow-up authorization resources.In the end in new data packets, if 23 bit space of residue are arranged, UE will be used to fill schedule information, and wherein indicating buffer state is 0, after Node B receives, judge and will regain resource after all data retransmissions in should the HARQ entity of UE are all accomplished.If UE has successfully transmitted all packets; And also do not accomplish (not having unnecessary space transmitting scheduling information) to NodeB indication transmission this moment; If also have remaining TTI resource this moment, UE can authorize at the next one and send schedule information on the TTI, and the indication buffer state is 0.
407:Node B gives RNC with the MAC data forwarding that receives after confirming that UE accomplishes the transmission of CCCH signaling.Node B confirms that UE accomplishes the method for transfer of data: resource has used up or has received the schedule information of UE, and wherein indicating buffer state is 0.
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.
