Abstract
The present invention relates to user equipment (UE) and method which facilitate high speed-downlink shared channel (HS-DSCH). The present invention discloses a method and system for the UE to perform a serial of actions in order to reduce the latency and potentially prevent loss of PDU transmission during the serving HS-DSCH cell change procedure. A new criterion is introduced for UE generation of the status report of RLC PDU. The UE generates status report of the PDUs as soon as possible following notification of the HS-DSCH cell change indicated by the RRC procedure to more efficiently recover source Node B buffered data. PDU status may be signaled for each AM RLC instance associated with the HS-DSCH transport channel. Furthermore, upon Inter Node B serving HS-DSCH cell change the SRNC may wait for PDU status report before initiating transmission of new data in target cell.
Description
The application be that April 2, application number in 2003 are 03807731.0 the applying date, name is called the dividing an application of Chinese patent application of " subscriber equipment and the method that contribute to high speed-downlink shared channel cell change ".
Technical field
The present invention relates to field of wireless communication.In more specific words it, recover buffered data after the present invention relates to switch in the wireless system from intermediate point distribute data effectively.Comprising the remote network control device (RNC) being coupled in one or more Node B and utilizing adaptive modulation and coding (AMC) and mix the third generation (3G) system automatically heavily send request (H-ARQ) technology (wherein said one or more Node B again successively wireless type be coupled on a plurality of subscriber equipmenies (UE)) is only an example of this kind of system.
Background technology
The third generation (3G) universal terrestrial radio access network (UTRAN) comprises several RNC, and wherein said each RNC all can be coupled in several Node B.Node B is the entity that comprises one or more base stations, wherein the flow of each one or more community of BTS management.
3G frequency division duplexing (FDD) and this RNC of time division duplex (TDD) system general using cushion and dispatch the data that (schedule) is transferred to this UE.Yet, with regard to the IA High Speed Channel of described 3G cellular system, be to cushion and dispatch by Node B the data that will transmit.One of them IA High Speed Channel is for example this high-speed downlink shared channel (HS-DSCH).This Node B of reason is carried out distribute data, therefore the data buffering that must will transmit is in Node B.This structure causes this RNC not obtain the last state of its control packet data community (PDU) transmission of this Node B.Therefore,, once switch in minizone, must coordinate with regard to this cell change the scheduling of described transfer of data.Not so, must be after this cell change, " leakage " or " repeats to transmit to make transfer of data re-synchronization, to avoid the data of transmission ".In 3G network, the switching of minizone is controlled by this RNC.Because being used for controlling the RNC that comprises GaiUE community, can change, therefore data are likely because this switching is missed or repeated.Because each RNC in this structure is associated with several Node B, cause this problem more serious.Due to the switching of UE community, therefore mobile UE requires the possibility that Node B changes to require RNC change to be greater more than it.
This HS-DSCH utilizes AMC to start high speed transmission data, and utilizes H-ARQ to increase the possibility of successfully transmitting data.When this UE must change this and transmitting and receiving the cell associated of UTRAN access point of this service HS-DSCH wireless link, cause serving HS-DSCH cell change.When replacing sense of community and improve to physical channel condition and/or entity capacity, cause this service HS-SDCH cell change.Be different from other channel in 3G network, this HS-DSCH be in Node B, interrupt rather than the RNC in this UTRAN on interrupt.
There are two kinds of HS-DSCH cell change types.When this UE changes two minizones that are associated with this same Node B, it is the service HS-DSCH cell change in Node B.When this UE changes two minizones that are associated with different nodes B, it is the service HS-DSCH cell change between a Node B.With regard to cell change between Node B, the Node B before this service HS-DSCH cell change is called to this source node B; And the Node B after this service HS-DSCH cell change is called to this target node b.
In this RNC and this UE, all have with layer wireless link and control (RLC) entity, provide and automatically heavily send request (ARQ) function as transmission data.This transmission RLC entity sends the sequence number (SN) in this PDU header with signal, and wherein this reception RLC entity utilizes this sequence number to guarantee not missing any PDU between this transmission period.When missed some PDU between this transmission period (because not transmitting in order due to PDU), this reception RLC entity transmit a PDU status report, to notify this transmission RLC entity " some PDU has missed ".Utilize this PDU status report that the state of this transfer of data is described.Wherein this PDU status report is identified described leakage or the sequence number SN of the PDU that receives.As missed PDU, the duplicate of the PDU that this transmission RLC entity can be missed this is transferred to this reception RLC again.
This transmission RLC entity also may receive RLC entity poll pdu status report to this; Or may produce termly status report.The state that this poll provides a mechanism, transmits for PDU described in this transmission RLC entity requests.
The H-ARQ function of this Node B also provides the function that failed transmission is transmitted again again.Although this H-ARQ operation meeting removes some failed transmission and improve the probability of successfully transmitting data, yet finally assure success, what transmit is this rlc protocol layer.
Due to the dynamic change of propagation conditions, thus this HS-DSCH cell change must be carried out rapidly, with maintenance service quality.During this service HS-DSCH cell change, this UE likely stops this and comes transmission in cell-of-origin and reception until while transferring all PDU being stored at present in this source node B.Because this data are dispatched and cushioned to this source node B, and for example, because of described message transmission rate very high (10,000,000 bps or higher), therefore (the particularly switching between Node B), the data that are buffered in this source node B in a large number likely can be missed when this UE carries out service HS-DSCH cell change.One of them is former because do not provide any mechanism in order to the buffered data in this source node B is transferred to this target node b in this UTRAN structure.Once HS-DSCH cell change is provided, because failing to give notice this RNC " data transmission scheduling of Node B " therefore this RNC does not know to have how many data loss to fall (if yes), and this RNC does not also know whether this UE has successfully recovery to confirm this transmission.Therefore once provide after HS-DSCH cell change, as still having data buffering in this source node B, this RNC RLC must recover these data, these data of unlikely leakage to keep transmission.
At present, prior art systems have two kinds preferably mode recover the buffered data in this source node B.After this HS-DSCH cell change: 1) this RNC can be clearly to this UE request PDU state; Or 2) this RNC can only come to suffer stopping place to start transmission cell-of-origin from this, and this UE examines by it not transmitting and will produce this PDU state in order of knowing.
In this first situation, this RNC by this UE of poll with request PDU state clearly, till this RNC must first wait until and set up this physical channel in Gai Xin community.Then, this RNC transmits this PDU status request, and this UE receives and process this request.This UE produces this PDU state, and this PDU state is returned to this RNC, and wherein this RNC processes this PDU state and determines which PDU need transmit again.
In this second situation, this RNC only comes to suffer stopping place to start to transmit PDU cell-of-origin from this, and these data of not transmitting in order of this UE identification are returned to this RNC with generation PDU state.This RNC processes this PDU state and learns which PDU need transmit again.
Any in above-mentioned two situations, while recovering the buffered data in this source node B as need, can remove to process PDU state; Yet, but seriously incured loss through delay the time that this UE its suitable reception is transmitted data again.This is to produce the time of this PDU state because having incured loss through delay this UE, thereby has incured loss through delay the time that this RNC receives this PDU state.
While carrying out transmission as recovered at RLC under affirmation mode, until can transmit data in proper order time, just send data to higher level.In this way, can require this UE to cushion these not sequenced data until can again transmit the PDU of described omission time.This has not only incured loss through delay this transmission, also requires this UE to have internal memory even as big as buffered data until can successfully transmit the data that are stored in this source node B simultaneously.Otherwise this effective speed can reduce, thereby affect service quality.Because internal memory is very expensive, so for designing improperly restrictive condition.
In this way, described before the buffered data of source node B is transferred to target node b, the art methods of first recovering this buffered data can produce extremely bad consequence.A kind of buffered data that can more have in the short period of time this source node B of efficient recovery, with the system and method for suitable maintenance customer's service quality demand, be more desirable.
Summary of the invention
The present invention a kind ofly carries out a succession of action so that shorten the described stand-by period during this service HS-DSCH cell change program and prevent that potentially PDU from when transmission, the method and system of leakage occurring.Introduce new criterion and produce this RLC PDU status report for UE.After having notified this indicated HS-DSCH cell change of this RRC program, this UE just autonomously produces this PDU status report as early as possible, more effectively to recover the buffered data of source node B.Can be (AM) RLC example (instance) of each affirmation mode being associated with this HS-DSCH transfer channel and send PDU state with signal.

Embodiment
Put up with described graphic explanation preferred embodiment of the present invention, wherein in all graphic in, the assembly of same number TYP.
According to the present invention, for after this service HS-DSCH cell change, shorten the stand-by period that this RNC obtains described PDU state and recovers the buffered data of this source node B, therefore after having notified this indicated HS-DSCH cell change of this RRC program, this UE just autonomously sends described PDU state to this RNC.The PDU state of this generation can be used for to each the AM RLC example being associated with this HS-DSCH transfer channel.
With reference to the flow chart of figure 1, illustrate a kind of according to the present invention, the effective method 10 of the buffered data of recovery nodes B.This RNC picks out need provide this HS-DSCH cell change (step 12).Then, notify this Node B " this service HS-DSCH cell change " (step 14).Notify this UE " this service HS-DSCH cell change " (step 16), as indicated via this RRC request message.Also note that may be before step 14 first invocation step 16 and without any disadvantageous consequence.
Once this UE, received this RRC request message (step 18), this UE after indicated this HS-DSCH cell change of notified this RRC program, produce as early as possible the status report (step 20) of this RLC PDU state of indication, to shorten time of delay when recovering the buffered data of this source node B.This UE do not wait in this arbitrary prior art triggering in order to produce PDU state (for example this RNC request produce PDU state, also or this UE detect do not transmit in order data).
This UE can carry out many different alternative methods, with initiation after service HS-DSCH cell change, produce PDU status report.Yet in this, several embodiment are proposed.Preferably, as the first selection, once buffering area, this MAC-hs of having removed this high speed medium access control (MAC-hs) its rearrangement, just notify this RLC.Second is chosen as this RRC notifies this RLC " to indicate the 3rd layer of (L3) RRC program of this service HS-DSCH cell change ".The 3rd, this physical layer can notify this RLC " to receive the HS-DSCH control channel in this Target cell "; Or once HS-DSCH control transitions to this Target cell, this physical layer can be notified this RLC.Those skilled in the art must can be appreciated that also has other method can want to send to from this UE in order to triggering the RLC PDU status message of this RNC.Due to this program, thus produce in the short period of time this PDU state and send this PDU state to this RNC (step 22), thus cause more effectively recovering the buffered data of source node B.
According to step 22, there are several to select to send this PDU status report to this RNC for this UE.The method of this PDU state of described transmission, for how this UE can send the embodiment (non-pre-requisite of the present invention) of this PDU state with signal to this RNC, is wherein to illustrate once there be new criterion, produces PDU state.Preferably, this UE produces RLC status report for each is mapped to AM RLC example on this HS-DSCH transfer channel.
In the second selection, this UE, once obtain PDU status report, sends this PDU status report to this RNC from this UE via this first current uplink message ".With regard to serving cell change in Node B (and supposing that this HS-DSCH transfer channel and radio bearer parameter do not change), the message on this DCCH is " physical channel has been reshuffled ".As this HS-DSCH transfer channel with radio bearer parameter has changed and/or with regard to Serving cell between Node B changes, the message on this DCCH is " transfer channel has been reshuffled ".Can in any RRC signaling message, identify this PDU state.Then, this RNC RRC entity notify this RLC " state of described PDU ", to continue to be again transferred to this target node b.
In the 3rd selects, by this, the status report about the upper new L3 signaling message of DCCH sends this RNC to from this UE to this UE.This new information is controlled to the rrc layer that (RRC) layer sends this RNC to from the Radio Resource of this UE.Then, this RNC notify this rlc layer " state of described PDU ", to continue to be again transferred to this target node b.In this way, the PDU status message shown in this Fig. 1 can comprise two different message " RRC " and " RLC state ".
The special format that note that this PDU status report can change.For example, the form of described PDU status report can comprise: 1) this sequence number (SN) of the described last in proper order PDU that success is transmitted; 2) this highest sequence number SN of the PDU that described success is received; 3) the sequence number SN of the described unsuccessful PDU receiving (PDU that leakage is fallen), wherein this highest sequence number SN of the paramount PDU receiving to described success; 4) or one lists the sequence number tabular of the PDU that reached merit receives.
Once this RNC, receive the message with this PDU state, this RNC RLC processes this PDU status message (step 24), to determine the PDU of described leakage.This RNC recognizes the data of missing because of this cell change now, and the data of this leakage can be transferred to again to this UE (step 26).Note that this message can have many kinds, and may not be only limited in " with this PDU status report ".
Also note that in this specific embodiment of the present invention, this RNC can be in step 16 and 24 data that continue will be transferred in this Target cell of transmission this UE.Because of as while transmitting the data of all bufferings in source node B unsuccessfully, the order of these data will disorderly fall, therefore can force this UE RLC to cushion these data, make data can pass in proper order higher level.This requires this UE to have one and enough stores the internal memory of the chaotic PDU of described order.After having missed any data in proper order, transmission is to be limited on the memory power of UE until successfully transmitted the data in proper order of this leakage.
Refer now to the flow chart of Fig. 2, illustrate a kind of according to the present invention another specific embodiment, the effective method 40 of the buffered data of recovery nodes B.Method 40 is similar to the method 10 shown in figure l, and described in Fig. 2, the mark of step is identical with figure l.Yet, this specific embodiment according to the present invention, method 40 comprises a new step 17, and wherein this RNC stops all down link HS-DSCH that lead to this UE and waits upon defeated until processed this PDU status message (step 24).The time that this specific embodiment postpones while making again to transmit the buffered data of source node B is reduced to the shortest, and has limited and must be buffered in the data volume on this UE.
With regard to this time of delay with regard to the shortizationest, this Node B is not also known the transmission sequence number of RLC, and the transmitting and scheduling in Node B is to take first in first out (FIFO) as basis.Therefore, as the RNC of this Target cell, while just passing on data before this PDU state is processed, can first transmit this data.It is longer that the data of this queue in Node B likely make again to transmit the required time of the buffered data of this source node B.
The present invention is applicable to the HS-DSCH cell change in cell change in cell change between Node B and Node B.In situation (case) in this Node B, this Node B can not be directed to the HS-DSCH data of this buffering this Target cell again due to indoor design problem, therefore this RNC can be designated as the needs that two kinds of situations produce PDU state.This UE also possibly cannot distinguish cell change in cell change and a Node B between a Node B, therefore also cause producing PDU state between Node B with Node B in two kinds of examples.With regard to the data transaction of this buffering cannot being given to the example of cell change between this Node B of this Target cell or in Node B, in this kind of mode, to transmit this PDU state be useful.
Although the present invention has been described in detail in detail, be understood that and do not limit the present invention to there, and can not depart from claim to the present invention in defined marrow and category in wherein doing all changes.
