Specific embodiment
The disclosure proposes the precedent transmission on how to handle old SPcell in multiple illustrative embodiments
Multiple solutions.Specifically, the disclosure proposes same for changing the UL of the old SPcell of process completion post processing in SPcell
Four kinds of embodiments of step state are completed to post-process the activation/deactivation state of old SPcell in SPcell change processes
Three kinds of embodiments handle previous downlink according to old SPcell activation/deactivations state（“DL”）The UE of transmission
Code of conduct/solution, the UL UCI how automatically restarted on old SPcell（“UCI”）It transmits and ensures
Five kinds of embodiments of the synchronization between SeNB and UE in such ULUCI transmission and how to handle previous UL objects
Manage uplink shared channel（“PUSCH”）It transmits and ensures the SeNB in the automatic UL PUSCH transmissions on old SPcell
Five kinds of synchronous embodiments between UE.
As previously mentioned, after SPcell change processes, old SPcell is converted to routine
Scell.Changed Cheng Qian in the SPcell, UL transmission, such as UL PUSCH are certainly existed on the old SPcell（Such as
UL HARQ process transmissions）Transmission, UL UCI transmissions, such as UL detection reference signals（“SRS”）, UL channel quality indicator
（“CQI”）, precoding matrix indicators（“PMI”）And order instruction（“RI”）Transmission etc..In addition, due to being reconfigured in SPcell
Cheng Qian, the old SPcell are always at state of activation, therefore cell packet data inactivity timer sCellDeactivationTimer
There is no operations.In consideration of it, the disclosure also proposed about corelation behaviours of the UE after SPcell reconfiguration courses with suitably
Handle the precedent transmission of old SPcell.
In short, after SPcell change processes are completed, for old SPcell, the disclosure is intended at least solve following ask
Topic：
Problem 1：How the uplink of old SPcell is handled（UL）It is synchronous（“SYN”）State；
Problem 2：After completing SPcell change processes in UE sides, the activation of old SPcell/deactivate how is handled or determined
State living；And
Problem 3：How the previous UL/DL data transmission of old SPcell and ULUCI transmission are handled.
Problem 1. handles the solution of old SPcell UL SYN
In order to ensure correct after SPcell change processes and suitably progress UL transmission, it should identify or determine and is old
The UL SYN states of SPcell, correctly to guide subsequent operations of the UE on old SPcell.For this purpose, under the disclosure proposes
Four illustrative embodiments in face, will lead to different UE behaviors：
Embodiment 1：When SPcell, which is configured, to be completed, UE stops timing advance timer（“TAT”）And then will
The UL synchronous regimes of old SPcell, which are considered as, in vain, that is, thinks UE and old SPcell uplink and asynchronous；
Embodiment 2：SPcell changes process and has no effect on the TAT timers being currently running, and UE will be
Its side checks the timer state after completing SPcell change processes, and
If TAT is still being run, UE and old SPcell uplink synchronous are confirmed；
Alternatively, if TAT stops during SPcell reconfiguration courses/expires, UE and old SPcell UL are same
Step is considered as invalid, that is, determines UE and old SPcell uplinks and asynchronous.
Embodiment 3：Complete after SPcell reconfigures, UE restart TAT timers and confirm UE with it is old
SPcell uplinks are synchronous；
Embodiment 4：The radio resource control that SeNB is transmitted in MeNB to UE（“RRC”）Increase in message additional
Instruction, perform corresponding action to indicate UE, such as stop TAT timers or keep the timer or restart timer
Deng.
According to disclosure embodiment discussed above, for embodiment 1, after the completion of SPcell change processes, such as
Fruit is still running for the TAT timers of old SPcell, then UE will stop the timer and think that old SPcell UL are same
Step state will be no longer valid.Then, UE will not perform any UL transmission until obtaining new timing on the old SPcell
In advance（“TA”）.If for example, the old SPcell is in is in identical timing advance group with new SPcell（“TAG”）
Interior, then it is also invalid that UE, which thinks that the UL of the new SPcell is synchronized,.For this purpose, any UL transmission on new SPcell is started
Before, UE will perform synchronous with the UL of new SPcell.Correspondingly, it is synchronized if obtaining new UL in new SPcell, such as
Uplink PRACH processes competition-based exempt from the uplink PRACH processes competed, then UL synchronous regimes of the UE on old SPcell
Also will automatically restart, so as to which UL transmission can restart.On the other hand, if old SPcell be in it is new
TAG different SPcell, then after SPcell change processes, it is invalid that SeNB, which will be appreciated by UE in the uplink synchronous of old SPcell,
's.For this purpose, SeNB will trigger new uplink random access procedure on old SPcell（Or it is known as uplink in this application
PRACH processes）, it is synchronous with the UL of old SPcell to obtain, so as to restart the transmission of the UL on old SPcell.
In R10/R11, when changing process by HO processes triggering Pcell, the TAT timers of all TAG of source eNB are all
It will be released.In comparison, for the embodiment 2 proposed by the disclosure, SPcell changes process does not influence old
The TAT operations of SPcell.That is, when UE side joints receive SPcell and change order, UE will not stop such as defined in R10
Only or discharge the timer.On the contrary, the TAT timers of the old SPcell of UE military orders continue to run with.SPcell is completed in UE sides to change
After change process, UE will check TAT states：
If TAT timers are still being run, it is still effective that UE thinks that old SPcell UL are synchronized.It is if old
SPcell is in the TAG identical with new SPcell, then it is also effective that UE, which will be considered to the uplink synchronous of new SPcell,.
Therefore, it is not necessary to uplink PRACH processes are performed on new SPcell, unless SeNB requirements UE is done so；
If TAT timers expire during SPcell change processes, UE can consider itself and old SPcell's
UL synchronizes no longer valid.At this point, SeNB can based on the corresponding TAT timer states of its own come detect the situation and really
It is invalid to determine UE to synchronize in the UL of old SPcell.Then, SeNB can or trigger UE to perform on old SPcell
Uplink PRACH processes or enable UE to determine when PRACH processes competition-based are regained with old SPcell's
UL is synchronized.
For embodiment 3, after SPcell change processes are completed, no matter the TAT timers situation of old SPcell such as
What, the TAT timers that UE will restart old SPcell.Next it may be determined that the uplink sync status on old SPcell.
SeNB sides, if detecting the uplink sync status on old SPcell and bad, such as based on old SPcell
Subsequent upstream transmission, then SeNB will trigger uplink PRACH processes on old SPcell with improve again UE with it is old
SPcell UL synchronous regimes.From this point of view, embodiment 3 is highly effective for realizing UE and old SPcell uplink synchronous.
For embodiment 4, SeNB can include indicating to control the behavior of UE by changing RRC information in SPcell
Or action.For example, after SPcell change processes, SeNB can indicate that UE performs the new uplink on old SPcell
PRACH processes.Then, in UE sides, the UL synchronizations for determining or knowing old SPcell have been considered as invalid by UE.Therefore, UE will
Any UL transmission will not be performed on old SPcell, it is synchronous with the UL on old SPcell until regaining.The opposing party
Face, SeNB may also require that UE TAT to be kept to run, and then after the completion of SPcell change processes, can be held in UE sides
Row is such as the operation rules defined in embodiment 2.
In short, above-mentioned four the proposed embodiments of the disclosure can lead to or obtain different UE behaviors, and
Ensure that operations of the UE on old SPcell can be performed correctly.
How problem 2. handles the activation/deactivation state of old SPcell
It is provided according to current R12DC, SPcell will always be at state of activation, therefore in phase life cycle of SPcell
Between, it should there is no the cell packet data inactivity timers of operation（“CellDeactivationTimer”）.Then, this is old
SPcell is converted into the Scell of a routine.And for the Scell of a routine, there should be different activation/go
State of activation, and the old SPcell should be associated with timer CellDeactivationTimer.
In view of above-mentioned, the disclosure suggests how three following embodiments are handled to handle after SPcell process changes
The activation/deactivation state of old SPcell：
Embodiment 1：It is state of activation to keep old SPcell；
Embodiment 2：It is deactivation status to keep old SPcell；And
Embodiment 3：Based on the SeNB being included in SPcell change RRC informations
Order come determine SPcell be in activation or deactivation status.
For embodiment 1, after the completion of SPcell change processes, old SPcell will be considered to be at activation shape
State.However, " activation " state of being somebody's turn to do is only temporarily " to activate ", and different from previous " always state of activation ".Then,
After SPcell change processes are completed, when old SPcell is considered as state of activation, UE should be automatically activated accordingly
SCellDeactivationTimer timers.After the timer expires, UE will be considered to the old SPcell relative to this
The state of activation of UE should be stopped and then be automatically brought into unactivated state.It can be seen that the completely new UE behaviors
It is considered based on the mode that triggered RRC information is run by timer sCellDeactivationTimer.
For embodiment 2, after UE completes SPcell change processes, old SPcell will be considered to be at inactive
State.Then, UE should discharge all corresponding mixed automatic repeat requests（“HARQ”）Process, so as to cause loss of data with
And subsequent redundant retransmission.The embodiment changes RRC information using SPcell and deactivates old SPcell to trigger UE, therefore
It can be considered as the Scell deactivating operations of RRC triggerings, and this is not prescribed by R10/R11.Because version previous
In, activation or deactivation are by medium access control（“MAC”）Control unit（“CE”）Come controlling rather than controlled by RRC processes
System.
For embodiment 3, SeNB provides new instruction in changing RRC information in SPcell, to guide UE behaviors.Example
Such as, if SeNB indicates that UE remains old SPcell relative to the UE to deactivate, UE, which should be performed, to be implemented
New operation defined in mode 1.On the other hand, if SeNB orders UE deactivates old SPcell, UE will perform implementation
New operation defined in mode 2.
No matter in short, take it is any in above-mentioned three kinds of embodiments, UE will ensure that its complete SPcell changed
Correct suitable operation is performed after journey.
How problem 3. handles the previous DL transmission of old SPcell
The problem is related to for after SPcell change processes, for old SPcell activation/deactivation states, i.e. problem
Which embodiment is taken in 2：
State of activation instruction is provided in RRC information for SeNB in the embodiment 1 in problem 2 or embodiment 3
Situation, after the completion of SPcell change processes, old SPcell will remain in state of activation.For the situation, the disclosure proposes
Following UE behaviors/operation：
UE will continue to safeguard and pause at the ongoing DLHARQ processes on old SPcell；
Further, UE continues to keep corresponding DL harq buffers device, until data are correctly received；
UE waits for the further DL dispatch of SeNB（Such as permit（“grant”））To restart or to discharge
The DLHARQ processes of these pauses on the old SPcell；
After SPcell change processes, UE will be automatically resumed the DL transmission for detecting the SeNB on old SPcell,
So as to which UE knows how to handle the DL HARQ processes of the pause on old SPcell.For example,
If SeNB is retransmitted by sending relevant DL licenses to UE on old SPcell to perform DL HARQ,
Recently the DL received is transmitted and is combined to transmit with the information buffered in corresponding buffer by UE；
On the other hand, if UE receives the DL licenses as new transmission, UE will be discharged to be delayed in corresponding HARQ
The information buffered in device is rushed, and the DL received transmission is considered as new transmission.
Alternatively, if taking embodiment 2 in problem 2 or taking embodiment 3 in problem 2 but SeNB will
UE is asked to deactivate old SPcell, then UE will discharge all DL harq buffers devices and SeNB is waited for dispatch new transmission.
In short, based on the above-mentioned each embodiment of the disclosure, it can be seen that the previous DL transmission on old SPcell
It will be treated correctly after the completion of SPcell change processes.
How problem 4. handles the previous UL transmission of old SPcell
As described above, changing Cheng Qian in SPcell, there are UL transmission, such as physical uplink certainly on old SPcell
Link sharing information（“PUSCH”）, PUCCH and UL UCI transmissions, including SRS, CQI/PMI/RI feedback etc..Then, exist
After the completion of SPcell change processes, it is thus necessary to determine that if handling existing UL HARQ operations, how and when restarting UE
Automatically carry out UL UCI transmissions etc..These problems are directed to which embodiment taken in problem 2 and problem 1.
As described in problem 2, when taking embodiment 2, the RRC processes triggering deactivation that SPcell changes is old
SPcell, UE will discharge all previous UL HARQ operations, and stop all ongoing UL UCI transmissions, without examining
Consider the UL synchronous regimes of old SPcell.
On the other hand, if taking the embodiment 1 in problem 3, i.e., after SPcell change processes, old SPcell will
State of activation is kept, if then it needs to be determined that handling UL UCI and UL the HARQ processes on old SPcell, as discussed below
's.For simplified description, it is assumed that the UL of SPcell old after SPcell change processes is synchronized and will be kept.Otherwise, again
Start old SPcell UL synchronize after, it will be considered that embodiment below：
How problem 4.1 after SPcell change processes restarts UL UCI transmissions
UL is transmitted, it is crucial the problem of be when UE will perform UL and transmit, it is necessary to ensure that eNB with UE be it is synchronous,
The UL transmission from UE can be received so as to eNB.In R10/R11, such as the UL UCI of UL SRS/PMI/RI/CQI etc. are passed
It is defeated to be configured by RRC information.Then, eNB will be appreciated by when UE will perform these UL transmission, such as be re-matched based on UL RRC informations
It puts and completes message.However in R12DC scenes, which will be no longer valid, because RRC agreements are only located at MeNB sides, and
SeNB does not know when MeNB receives RRC and reconfigure and completes message.That is, SeNB is difficult to know these automatic UL UCI transmissions
When will start, therefore SeNB is difficult and is less likely to receive UL UCI transmissions on old SPcell.In order to solve this
Problem, the disclosure propose following embodiment：
Embodiment 1：UE restarts triggering UE old when completing uplink PRACH processes on new SPcell
SPcell on UL UCI transmissions.Similarly, UE can also be according to the execution uplink PRACH processes on old SPcell of completing
To trigger the UL UCI transmissions restarted on old SPcell；
Embodiment 2：UE starts triggering UE when carrying out UL UCI transmissions on new SPcell in old SPcell
On restart automation UL UCI transmissions；
Embodiment 3：First dispatch is received on new SPcell（For example, license）When will triggering UE exist
UL UCI transmissions on old SPcell.That is, the data transmission for the first time on new SPcell will trigger UE in old SPcell
On restart UL UCI transmissions；
Embodiment 4：Dispatch is received on old SPcell or is received and indicates old SPcell transmission
UE will be triggered to perform UL UCI transmissions in old SPcell during dispatch.That is, the data for the first time on old SPcell pass
Contribute's triggering restarts UL UCI transmissions on old SPcell；
Embodiment 5：New MAC CE are designed, so as to which SeNB can ask UE to perform old by the MAC CE
SPcell on UL UCI transmissions；
Embodiment 6：Indicate UE on old SPcell by coming from the activation/deactivation MAC CE of SeNB
Perform UL UCI transmissions.For the embodiment, no matter which kind of state old SPcell is in, if SeNB wishes UE old
Start UL UCI transmissions on SPcell, then SeNB will send downwards the activation/deactivation MAC CE of instruction " activation " state.And
At UE sides, when receiving the first MAC CE, UE will automatically restart the UL UCI transmissions on old SPcell.It should
Embodiment is similar to the embodiment 5 that wherein UE behaviors are controlled by SeNB, but the difference lies in embodiment 6 for this purpose
And activation/deactivation MAC CE are used.
For embodiment 1, the time point when UE is completed in the uplink PRACH processes on new SPcell will be used for together
Walk UL UCI transmissions of the UE and SeNB on old SPcell.For example, for the PRACH processes from competition, message 2 is being sent
Afterwards, SeNB knows that UE will be in some period（Such as 4 milliseconds）Restart to perform UL UCI transmissions on old SPcell afterwards.
And in UE sides, when after message 2 are received on new SPcell, UE will be in some period（Such as 4 milliseconds）After restart
UL UCI transmissions are performed on old SPcell.For another example for PRACH processes competition-based, when the transmission of message 4 is used as
Between point synchronize the UL UCI transmissions of UE and SeNB on old SPcell.That is, after message 4 are received, UE will be after 4 milliseconds
Restart UL UCI transmissions on old SPcell, as shown by the embodiment 1 in Fig. 2.
For embodiment 2, when UE starts to perform in the UL UCI transmissions on new SPcell, either by which kind of reality
The mode of applying triggers, and UE will automatically proceed by its UL UCI transmission on old SPcell, this is will be appreciated that for SeNB
When UE will start the UL UCI transmissions on new SPcell.Then, for embodiment 2, when SeNB also will be appreciated by UE
It will start the UL UCI transmissions on old SPcell.It is that is, synchronous in the UL UCI transmissions of UE and SeNB on old SPcell.
The synchronization scenario may refer to embodiment 2 shown in Figure 2.
For embodiment 3, when UE on new SPcell when receiving dispatch, UE will by the use of the reception as when
Between point restart its UL UCI transmission on old SPcell.Reason is that SeNB knows UE when in new SPcell
Upper reception dispatch and therefore SeNB will be appreciated by when UE will start its UL UCI transmission on old SPcell.That is,
The reception of dispatch on new SPcell is used as synchronous UE and SeNB to perform UL UCI transmissions in old SPcell.
Shown in the embodiment 3 in Fig. 2,4 milliseconds after first PDCCH are received on new SPcell, UE will be
UL UCI transmissions are performed on old SPcell.
For embodiment 4, when receiving dispatch on old SPcell or instruction is received old
During the dispatch transmitted on SPcell, UE will restart its UL UCI transmission on old SPcell.Reason and embodiment party
Formula 3 is similar, because SeNB is aware of when that the dispatch for being directed to old SPcell will be received and therefore SeNB should
Know when UE will restart the UL UCI transmissions on old SPcell.Referring to shown by the embodiment 4 in Fig. 2,
4 milliseconds after the first PDCCH received on old SPcell, UE will carry out UL UCI transmissions on old SPcell.
Above-mentioned embodiment 1-4 is directed to the automatism of UE, and the difference lies in each embodiments to have not
Same UL UCI transmissions triggering benchmark or reference.Nevertheless, SeNB can also order UE to perform UL UCI transmissions, such as implement
Proposed by mode 5.R10 is similarly to, wherein UL UCI transmissions are triggered by RRC processes.That is, it is considered that R10/R11UL
UCI transmission is asked by eNB based on RRC processes.In comparison, in R12DC, due to there is no RRC agreements at SeNB,
The disclosure suggests that SeNB restarts the UL UCI transmissions on old SPcell come order UE by MAC CE.For this purpose, this public affairs
It opens and proposes a kind of new MAC CE, which has fairly simple form.For example, the MAC CE only include MAC CE reports
Head and be not followed by MAC CE payloads（Data portion）, and sub-header is only a byte, i.e. R/R/E/LCID, in Fig. 3
Shown by last point, defined in a new Logic Channel Identifier（“LCID”）, UL UCI will be performed by being used to indicate UE
Transmission.Optionally, as shown by next part in Fig. 3, the MAC CE payloads of a byte can be included in the MAC CE,
Instruction UE should perform UL UCI transmissions in which cell.Which is effective and simple, because existing in SeNB
MAC entity.By the above embodiment, the disclosure can be obtained as triggered UL UCI transmissions by RRC information in R10/R11
Same performance.
For embodiment 6, SeNB activation/deactivation MAC CE are used to trigger UE to restart in old SPcell
UL UCI transmissions.Therefore, the present disclosure defines new UE behaviors：It is first to activate/deactivate after SPcell change processes are completed
MAC CE living will trigger UE and perform UL UCI transmissions.
In short, it is feasible that the above embodiment 1-6 restarts UL UCI transmissions for guiding UE on old SPcell
's.Particularly, embodiment 5 ensures that UE and SeNB are fully synchronized in next UL UCI transmissions, so as to reach with
Performance similar R10/R11.
How problem 4.2 after SPcell change processes restarts UL PUSCH transmissions
As noted above, another major issue is how to be handled after the completion of SPcell change processes old
Previous ongoing UL PUSCH transmissions on SPcell（That is, data transmission）.The problem in execution SPcell with changing
Cheng Hou, how to be handled on old SPcell in problem 1 embodiment that UL is synchronized it is related and in problem 2 such as where
The embodiment for managing the activation/deactivation state of old SPcell is related.If it takes the embodiment 2 in problem 2 or takes
Embodiment 3 but old SPcell is deactivated by SeNB requests, then UE should discharge all ongoing UL HARQ processes simultaneously
And also discharge all relevant harq buffer device information.
On the other hand, if thinking that old SPcell is active after SPcell change processes, the disclosure is built
View performs following operation and previously ongoing UL PUSCH is performed on old SPcell to handle.Following discussion is based on
Assuming that it confirmed that UE is synchronous with the UL of old SPcell.
Embodiment 1：Although after the completion of SPcell change processes, old SPcell is maintained as state of activation,
UE will discharge all ongoing ULHARQ processes and discharge all UL harq buffer devices；
Embodiment 2：UE maintains and suspends all ongoing UL HARQ processes.In addition, UE will keep being directed to
In all UL harq buffers devices for the HARQ processes for receiving NACK before this.It is successfully completed on new SPcell in UE
After UL PRACH processes, UE will automatically restart UL transmission on old SPcell（Non-adaptive HARQ is retransmitted）；
Embodiment 3：Similar to embodiment 2, UE maintains and suspends all ongoing UL HARQ processes.Separately
Outside, all UL harq buffers devices that UE will keep the HARQ processes for before receiving in view of this NACK.It is successfully completed in UE
After new SPcell receives first dispatch, it is non-adaptive heavy that UE will automatically restart UL on old SPcell
It passes；
Embodiment 4：Similar to embodiment 2, UE maintains and suspends all ongoing UL HARQ processes.Separately
Outside, all UL harq buffers devices that UE will keep the HARQ processes for before receiving in view of this NACK.But different from embodiment
2, UE should wait for the further UL dispatch for coming from SeNB, to restart the UL that UL retransmitted or discharged these preservations
Harq buffer device.That is, the first UL dispatch received on old SPcell will restart the UL of all pauses of UE
HARQ process operations.
Embodiment 5：Similar to embodiment 2, UE will keep being directed to the HARQ processes of previously received NACK
All UL harq buffers devices.But different from embodiment 2, UE should wait for the further UL dispatch for coming from SeNB,
Corresponding ULHARQ buffers are retransmitted or discharge to restart UL.That is, the UL scheduling letters received on old SPcell
Order will only restart corresponding UL HARQ process operations.If being not received by corresponding UL dispatch, UE should be after
Continuous pause others HARQ processes.
For embodiment 1, after SPcell change processes are completed, even if old SPcell still in state of activation,
UE discharges all ongoing UL harq buffers devices.Therefore, which will lead to unnecessary redundant retransmission but have
The advantage of relative simplicity.
For embodiment 2, UL harq buffers device and ongoing UL HARQ processes are safeguarded.When UE is new
After completing uplink PRACH processes on SPcell, UE will automatically start the UL HARQ processes of those previously received NACK
Non-adaptive UL HARQ on old SPcell are retransmitted.For the embodiment, the reception of message 2 or message 4 will act as together
The time point of UL transmission of the SeNB and UE on old SPcell is walked, as shown in Figure 4.
For embodiment 3, embodiment 2 is similar to, and the difference lies in work as to receive on new SPcell
During first dispatch, UE will restart the non-adaptive HARQ of its UL on old SPcell and retransmit.That is, new
First dispatch on SPcell will act as the time point that UL HARQs of the synchronous SeNB and UE on old SPcell is retransmitted,
As shown in Figure 5.
For embodiment 4, UE will not restart its UL HARQ operation, until receiving head on old SPcell
A dispatch.For the embodiment, UL HARQ processes that only one dispatch will restart all current hangs.
For example, permitted in UE based on the UL in receiving TTI i come after performing corresponding UL HARQ transmissions, though be not received by into
The UL licenses of one step, UE will continue to perform non-adaptive UL HARQ re-transmissions in subsequent TTI, as shown in Figure 6.
For embodiment 5, UE will keep and safeguard all ongoing UL HARQ processes.UE will not be opened again
Begin the UL HARQ processes suspended, until receiving corresponding UL dispatch on old SPcell.That is, when old
When UL dispatch is received on SPcell, UE will only restart corresponding UL HARQ processes, but continue to keep other
UL HARQ suspend.This means that a UL dispatch will only restart a UL HARQ process, this differs markedly from reality
Apply mode 4.As shown in Figure 7, it is assumed that first dispatch is associated with UL HARQ process i, then UE will be by according to receiving
Dispatch performs adaptive re-transmission or performs new transmission, and restarts ULHARQ processes.In next TTI, by
In being not received by corresponding dispatch, UE will continue to suspend UL HARQ process i+1, as indicated by " X " in figure.Rear
In continuous TTI, due to receiving dispatch again, UE will further restart UL HARQ processes i+2 and perform by connecing
The adaptive retransmission indicated by dispatch received or new transmission, and identical process will be carried out persistently.It should be understood that
Be that process here represents that i, i+1, i+2 or i+n etc. are only exemplary, and n according to the difference of original bench mark position and
Suitable value can be taken.
In short, embodiment 1-5 is feasible for the ULHARQ processes for restarting pause on old SPcell, because
It is synchronous with UE on the time point that should restart UL transmission on old SPcell as UE for SeNB.
