Description
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus of the lower reporting links state of high speed downlink packet access (High Speed Downlink Packet Access is called for short HSDPA) multithread configuration and configuration link.
Background technology
Along with the continuous fast development of data service, high speed uplink downlink packet access (High Speed Uplink Packet Access is called for short HSPA) technology is more and more widely used, and to the future development of multi-antenna multi-carrier-wave.Such as, third generation partner program (3rd Generation Partnership Project, be called for short 3GPP) R7 version introduced multiple-input, multiple-output (Multiple-Input Multiple-Output, be called for short MIMO) technology, make Node B (NodeB) to send two transmission blocks to subscriber equipment (UE) from same community by double antenna simultaneously, under different spaces environment, improve data rate or provide velocity of wave to embark on journey advantage to UE; Subsequently, the R8 version of 3GPP has been introduced dual carrier HSDPA (DC-HSDPA) technology, in R9, introduce double frequency-band DC-HSDPA, made NodeB to send HSDPA data to UE from the different frequent points that has intersection to cover Liang Ge community simultaneously, improved the user's impression across whole cell coverage area.
When UE is in edge, two co-frequency cells and carry out soft handover or when More Soft Handoff, often serve the limited ability of eating dishes without rice or wine of HS-DSCH community, and non-service HS-DSCH community in Active Set also has available resources, if can allow non-service cell also send out data to UE as another Serving cell, will greatly improve user's impression, thereby also improve the data throughout of community.Therefore, the R11 version of 3GPP enters on the multithread technology of HSDPA.Distinguish according to the node of shunting, HSDPA multithread technology is divided between the interior shunting of NodeB and NodeB to be shunted.
Report the standard of down-going synchronous state to be divided into two stages.Have for each the down link that activates upstream frequency, UE will carry out these two stages one time, and corresponding down-going synchronous primitive is also reported to high level.Physical layer indicates (CPHY-Sync-IND) and physics step-out instruction (CPHY-Out-of-Sync-IND) two primitive to inform the synchronous regime of the down link that activates upstream frequency by physical layer synchronization.
When high level starts, dedicated physical channels is set up or UE starts synchronous flow process A or synchronous flow process AA, and the first stage is activated, and descending dedicated channel is thought that by high level setting up rear this first stage continues 160ms.At previous 40 milliseconds, UE estimates downlink physical control channel quality or receives the quality of the transmitting power control domain fragment dedicated physical channel frames from related service high speed descending sharing channel community, if its quality is better than threshold value Qin, report synchronous regime, do not report desynchronizing state.Wherein, if in the time of not the completing of the downlink physical control channel mass measurement of 40ms, this standard hypothesis is not performed.Wherein, Qin is by dependence test implicit difiinition.
Think 160ms after descending dedicated channel has been established when high level, second stage starts.In this stage step-out be synchronously in the news according to different situations.
In the following cases, step-out primitive CPHY-Out-of-Sync-IND is reported to high level, informs the descending step-out of UE:
One, be false if upstream discontinuous transmits activation (UL_DTX_Active), the estimation cycle is previous 160 milliseconds.UE estimation Dedicated Physical Control Channel quality or the quality from the through-put power control domain of the fragment DPCH of primary/secondary service high-speed downlink shared channel in this cycle, its mass value is also poorer than threshold value Qout, report step-out primitive, wherein Qout determines by dependence test is implicit.
Two, be true if upstream discontinuous transmits activation (UL_DTX_Active), the estimation cycle is previous 240 milliseconds.UE estimation Dedicated Physical Control Channel quality or the quality from the through-put power control domain of the fragment DPCH of primary/secondary service high-speed downlink shared channel in this cycle, its mass value is also poorer than threshold value Qout, reports step-out primitive.
Three, all transmission channels all use non-zero length CRC to match downlink dedicated data channel, and 20 transmission blocks that CRC is corrected in the circulation with non-zero of receiving are recently found to be whole CRC check failures.In addition, at previous 160 milliseconds, all reception pieces of CRC are corrected in all circulations of adhering to non-zero length, and its CRC check is all incorrect, reports step-out primitive.
For DPCH, in following situation, use synchronization primitives CPHY-Sync-IND to report to upper strata synchronous regime:
One, on 160 previous millisecond periods, the downlink physical control channel quality of UE estimation is better than threshold value Qin, reports synchronization primitives.
Two, all transmission channels all use non-zero length cyclic redundancy check (CRC) (Cyclic Redundancy Check, be called for short CRC) match downlink dedicated data channel, at certain Transmission Time Interval (Transmission Time Interval of present frame, be called for short TTI) while finishing the circulation of at least one non-zero to correct the transmission block of CRC be correct by CRC check, report synchronization primitives.If do not have transmission block to be received, or the transmission block that finishes not have the circulation of non-zero to have in correcting the transmission block of CRC and previous 160 milliseconds the circulation of a non-zero to correct CRC at certain TTI of present frame is correct by CRC check, just supposes that this standard meets.If the transmission block no one of the circulation of non-zero correction CRC receives in previous 160 milliseconds, this standard is also supposed to meet.In the situation that TFCI is not used, for not using the circulation of non-zero to correct and do not use the transmission channel of the detection of guide property in all transformats, this standard is not considered.
For fragment DPCH, in following situation, report synchronization primitives CPHY-Sync-IND to high-rise.
One, if upstream discontinuous transmits and activates (UL_DTX_Active) is false, on 160 previous millisecond periods, the quality of the through-put power control domain of the fragment DPCH from service high-speed downlink shared channel of UE estimation is better than threshold value Qin, report synchronization primitives CPHY-Sync-IND to high-rise, wherein, Qin determines by dependence test is implicit.
Two, if upstream discontinuous transmits and activates (UL_DTX_Active) is true, on 240 previous millisecond periods, the quality of the through-put power control domain of the fragment DPCH from service high-speed downlink shared channel of UE estimation is better than threshold value Qin, report synchronization primitives CPHY-Sync-IND to high-rise, wherein, Qin determines by dependence test is implicit.
Before introducing HSPDA multithread, define respectively step-out behavior for downward special physical channel and two scenes of fragment DPCH and reported.For having configured descending professional physical channel, step-out standard is the estimation on all downlink data physical channels.For the UE that has configured descending professional fragment physical channel, step-out standard is only on the fragment down physical channel of service high-speed downlink shared channel community, to estimate.Introduce after multithread, current industry is reached common understanding, and is exactly that step-out and synchronous judgement flow process are constant, continues to use the synchronous and step-out criterion of non-multithread, for the UE that configures multithread and downward special physical channel, and industry its step-out behavior of reaching common understanding.But for configuration multithread and descending fragment DPCH, for the operation and the minimizing that improve terminal there is no need Radio Link Failure, ductile step-out and synchronous criterion are proposed.Because if the estimation of the fragment DPCH still based on service high-speed downlink shared channel step-out, determines Radio Link Failure, seem a little too fierce, because UE and assistance services tell DSCH Downlink Shared Channel community keeping contacting in signaling.So-called step-out of extending and synchronous criterion, tell UE to carry out descending step-out estimation in service and assistance services respectively, and when Qie Dangliangge community all meets descending step-out standard separately, descending step-out flow process is triggered.In the time of step-out, if share community or meet synchronization criterion from the fragment DPCH in assistance services high-speed downstream community from service high-speed downlink, step-out flow process is stopped, and is descendingly considered to synchronous.Follow-up further discussion, thinks that this ductile step-out and synchronous criterion there is no need to introduce, and think that gain is little.This ductile criterion is to be based upon the signal scene better than the signal quality of Serving cell of assisting community, and this is infrequent conventionally, is all the best community of signal quality conventionally because mobility principle specifies Serving cell.Even if this scene has occurred, assist community can not change the configuration of terminal, data are not parked in thinks that Serving cell sends, and step-out of Serving cell, the gain that has not had multithread to bring.Because terminal can not start cell update flow process, even can enter a deadlock state again.So suggestion is still used original step-out and synchronous criterion, the step-out based on Serving cell and synchronous judgement, to better start cell update flow process, allow network side know earlier the situation of current wireless link, carries out new suitable configurations to terminal.
Descending step-out main cause is the factors such as wireless environment is bad, interference, weak covering.In non-multithread situation, multilink transmits identical data flow.When a link synchronization failure, data are communicated to UE by good wireless link, and the wireless link of step-out can be deleted by measurement procedure.All down link step-outs, can recover by cell update (Cell Update) process the call drop of trying not.Multithread is to transmit different data flow at different links.A certain the descending step-out of link, the link transmission that the data flow that transmission is not gone down can be rescheduled to, the wireless link wait measurement procedure of this step-out is deleted.But under this background of multithread, can cause the network side configuration that can not upgrade in time, cause the waste of resource.Such as balanced control of data traffic of same frequency double small district's multithread of Fig. 1 cross-node B (being called for short SF-DC), the descending step-out of wireless link between NodeB1 and UE, cause the data of NodeB1 can not send in time UE to, radio network controller (RNC) can be rescheduled to the data of NodeB1 NodeB2 and send.But in order to maintain, business is up to be existed always, possible signal neither be fine for NodeB1, NodeB1 side can receive the channel quality the reporting instruction from UE always, but NodeB1 can estimate certain ability capability value to RNC always, then RNC has and can send data to NodeB1, the data of NodeB1 side can transmit to go down for the second time, the data dispatch that RNC side can not transmit down NodeB1 again transmits to NodeB2, go round and begin again, caused the waste of complexity and the resource of data transfer procedure.
