Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

Fig. 1 is the flow chart of a method for handling carriers of the present invention embodiment, and as shown in Figure 1, the method for the present embodiment can comprise:

Step 101, start timer respectively for each carrier wave entering state of activation in polymerization carrier wave.

For example, after any one carrier wave in polymerization carrier wave enters state of activation, UE all can start timer for this carrier wave, and therefore UE can start timer respectively for multiple carrier wave.

Particularly, suppose that having four carrier waves provides service for UE, is respectively CC1, CC2, CC3 and CC4.In the prior art, suppose that CC1 is main carrier, then CC1 can be in state of activation in DRX cycle always, and when UE receives data on CC1, UE needs to start InactivityTimer, and all non-main carriers are also activated, at the end of InactivityTimer timing, all carrier waves, comprise main carrier and non-main carrier is all deactivated.But, due to different carrier waves, its scheduling time can be different, also namely after non-master carrier activation, be not all have transfer of data on all non-main carriers, and all non-main carriers can only just by unified deexcitation at the end of DRX cycle, for the situation not setting main carrier, the active mode of each carrier wave is more flexible, but each carrier wave all can only just by unified deexcitation at the end of DRX cycle.Therefore, when certain carrier wave there is no transfer of data, the power dissipation of UE when it is in state of activation, can be caused.

Correspondingly, in the present embodiment, UE can start timer for the carrier wave after activation.For example, be the situation of main carrier for CC1, after UE receives data on CC1, CC2 ~ CC4 is activated, and UE can start timer respectively for CC2 ~ CC4.This timer is used for controlling the deexcitation time of CC2 ~ CC4.For the situation not setting main carrier, the activationary time of CC1 ~ CC4 can be identical, also can be different, and therefore, UE can after in CC1 ~ CC4, each carrier wave be activated respectively, for the carrier wave after these activate starts timer respectively.

Whether the carrier wave that step 102, detection start timer receives data in the timing time of described timer.

For example, be the situation of main carrier for CC1, whether UE the upper detection of CC2 ~ CC4 upon activation can have transfer of data; For the situation not setting main carrier, UE can detect whether have transfer of data on CC1 ~ CC4.

If the carrier wave of the described startup timer of step 103 does not receive data in the timing time of the timer of correspondence, then deexcitation process is carried out to this carrier wave.

UE can in the timing time of timer carrier wave upon activation, whether the upper detection of such as CC2 ~ CC4 receives data, if UE does not receive data in timing time on CC2, then UE when the timing time of the timer corresponding with CC1 arrives, can carry out deexcitation process to CC2.In like manner, if UE does not also receive data in timing time on CC3 or CC4, then UE when the timing time of the timer corresponding with CC3 or CC4 arrives, can carry out deexcitation process to CC3 or CC4 respectively.Those skilled in the art can set the timing duration of this timer as required.And, carrier wave in the present embodiment can comprise Physical Downlink Control Channel (PhysicalDownlinkControlChannel, be called for short: PDCCH) and Physical Downlink Shared Channel (PhysicalDownlinkSharedChannel, be called for short: PDSCH).

It should be noted that, the present embodiment does not limit the active mode of each carrier wave, those skilled in the art can adopt any one active mode to carry out activation process to each carrier wave, therefore, the activationary time of each carrier wave can be the same or different, and UE only needs to start timer according to the activationary time of each carrier wave.

In the present embodiment, UE can start timer respectively for the carrier wave after activation, if this carrier wave does not receive any data in the timing time of timer, then deexcitation process is carried out to this carrier wave, thus avoid the problem being also always in state of activation when occurring carrier wave not receiving data, therefore, the power loss of UE is reduced.And DRX cycle is just deactivated after terminating not have the carrier wave of transfer of data also need not wait until, therefore, the deexcitation mode of carrier wave is comparatively flexible always.

Particularly, the embodiment of the present invention can adopt five kinds of implementations to realize the method for handling carriers embodiment shown in Fig. 1, is described successively below.

Wherein, following manner one and mode two can start respectively for each carrier wave entering state of activation non-ly restarts type timer, and this is non-restarts type timer and do not carry out reboot operation when the carrier wave of correspondence receives data.Mode three and mode four can start respectively for each carrier wave entering state of activation restarts type timer, this restart type timer correspondence carrier wave receive data time carry out reboot operation.Mode five can start respectively for each carrier wave entering state of activation non-ly restarts type timer, and arranges one and common restart type timer for all state of activation carrier waves that enters.

Specifically, the implementation of each mode is as follows:

Mode one can comprise:

1) after carrier wave enters state of activation, type timer is restarted for described carrier wave startup is non-.

2) detect described carrier wave and whether receive data in non-timing time of restarting type timer.

3) if described carrier wave does not receive data in the timing time of timer, then deexcitation process is carried out to described carrier wave; If described carrier wave receives data in non-timing time of restarting type timer, then stop described non-Clocked operation of restarting type timer, and time-out carries out deexcitation process to described carrier wave when DRX inactive timer.

In this implementation, UE is the timer that the carrier wave after activating starts is non-ly restart type timer, and namely this non-ly restarts type timer once start, and this carrier wave is follow-up when receiving data, and this is non-restarts type timer and can not restart timing, but stops Clocked operation.

For example, suppose that CC1 is main carrier, then CC1 is state of activation in whole DRX cycle, and when CC1 receives data, CC2 ~ CC4 is activated, and now UE non-ly can restart type timer for CC2 ~ CC4 starts respectively.Suppose that CC2 have received data in non-timing time of restarting type timer, then UE will stop the non-Clocked operation of restarting type timer corresponding with CC2, then CC2 is in state of activation always, until at the end of DRX cycle, also the moment of i.e. main carrier deexcitation, just deexcitation.Suppose that CC3 does not receive data in non-timing time of restarting type timer always, then UE is when non-timing time of restarting type timer arrives, and can carry out deexcitation process to this CC3.For the processing procedure of CC4 and said process similar, repeat no more.For the situation not presetting main carrier, the deexcitation principle of CC1 and the deexcitation principle of above-mentioned CC2, CC3 or CC4 similar, repeat no more.

Therefore, in this implementation, UE can start non-type timer of restarting respectively for the carrier wave after activation, if this carrier wave does not receive any data in non-timing time of restarting type timer, then UE can carry out deexcitation process to this carrier wave, thus avoid the problem being also always in state of activation when occurring this carrier wave not receiving data, therefore, reduce the power loss of UE.And, for the carrier wave not having transfer of data, UE can carry out deexcitation process when non-timing time of restarting type timer arrives to this carrier wave, deexcitation process is carried out at by the time DRX cycle again after terminating for there being the carrier wave of transfer of data, therefore, the deexcitation moment of each carrier wave can change flexibly according to the data dispatch situation on this carrier wave.

Mode two can comprise:

1) after carrier wave enters state of activation, type timer is restarted for described carrier wave startup is non-;

2) detect described carrier wave and whether receive data in described non-timing time of restarting type timer;

3) if described carrier wave does not receive data in non-timing time of restarting type timer, then deexcitation process is carried out to described carrier wave; If described carrier wave receives data in non-timing time of restarting type timer, then stop described non-Clocked operation of restarting type timer; Restart type timer for described carrier wave starts, and when described carrier wave receives data at every turn, described in restarting, restart type timer, when described restart type timer or DRX inactive timer time time-out time, deexcitation process is carried out to described carrier wave.

In this implementation, UE is the timer that the carrier wave after activating starts is non-ly restart type timer, namely this non-restart type timer once start, when this carrier wave receives data, this is non-restarts type timer and can not restart timing, but stops Clocked operation, then UE restarts type timer starting one for this carrier wave, namely this restarts type timer once start, and this carrier wave is follow-up when receiving data again, all will restart type timer and restarts this at every turn.

For example, suppose that CC1 is main carrier, then, when CC1 receives data, CC2 ~ CC4 is activated, and now UE non-ly can restart type timer for CC2 ~ CC4 starts respectively.Suppose that CC2 have received data in non-timing time of restarting type timer, then UE will stop the non-Clocked operation of restarting type timer corresponding with CC2, and restart type timer for CC2 starts one, if CC2 is restarted in the timing time of type timer receive data at this, then this is restarted type timer and restarts timing, if CC2 is restarted in the timing time of type timer do not receive any data at this, when then should restart any one time-out in type timer or the inactive timer of DRX, namely deexcitation process is carried out to CC2, therefore, if CC2 does not receive any data in the timing time of restarting type timer, when the timing time of the timing time of restarting type timer timer more inactive than DRX first arrives, then the deexcitation moment of CC2 is the timing time due in that this restarts type timer, this moment is early than the due in of the timing time of the inactive timer of DRX, also namely early than the moment that DRX cycle terminates, when the timing time of the inactive timer of DRX first arrives than the timing time of restarting type timer, then the deexcitation moment of CC2 is the timing time due in of the inactive timer of this DRX, also it is the moment that DRX cycle terminates.Suppose that CC3 does not receive data in non-timing time of restarting type timer always, then UE is when non-timing time of restarting type timer arrives, and can carry out deexcitation process to this CC3.For the processing procedure of CC4 and said process similar, repeat no more.For the situation not presetting main carrier, the deexcitation process of CC1 ~ CC4 can adopt the processing mode of CC2 or CC3, repeats no more.

Therefore, in this implementation, UE can start non-type timer of restarting respectively for the carrier wave after activation, if this carrier wave does not receive any data in non-timing time of restarting type timer, then UE can carry out deexcitation process to this carrier wave, if this carrier wave receives data in non-timing time of restarting type timer, then UE can restart type timer for this carrier wave starts, only when restarting any one timer expired in type timer or the inactive timer of DRX, then deexcitation process is carried out to this carrier wave.Therefore, this implementation can reduce the power loss of UE, and, for not having the carrier wave of transfer of data in non-timing time of restarting type timer, receive data and in the timing time of restarting type timer started, do not receive the carrier wave of data and in non-timing time of restarting type timer, receive data and in the timing time of restarting type timer started, receive the carrier wave of data in non-timing time of restarting type timer, its deexcitation moment can change flexibly according to the data dispatch situation on this carrier wave.

Mode three can comprise:

1) after carrier wave enters state of activation, type timer is restarted for described carrier wave starts;

2) detect described carrier wave and whether receive data in described timing time of restarting type timer;

3) if described carrier wave does not receive data in the timing time of restarting type timer, then deexcitation process is carried out to described carrier wave; If described carrier wave receives data in the timing time of restarting type timer, type timer is restarted described in then restarting, and when described carrier wave receives data at every turn, type timer is restarted described in restarting, when described restart type timer or DRX inactive timer time time-out time, deexcitation process is carried out to described carrier wave.

In this implementation, UE is the timer that the carrier wave after activating starts is restart type timer, and namely this restarts type timer once start, and this carrier wave is follow-up when receiving data again, all will restart type timer and restarts this at every turn.

For example, suppose that CC1 is main carrier, then, when CC1 receives data, CC2 ~ CC4 is activated, and now UE can restart type timer for CC2 ~ CC4 starts respectively.Suppose that CC2 have received data in the timing time of restarting type timer, then UE can be restarted this and be restarted type timer, make this restart timer and restart timing, if CC2 this restart in the next timing time of type timer do not receive any data and the timing time of the inactive timer of DRX does not also arrive time, the timing time that then UE can restart type timer at this carries out deexcitation process to CC2 when arriving, if the timing time that CC2 restarts the inactive timer of DRX in the next timing time of type timer at this arrives, then UE also will carry out deexcitation process to CC2.Therefore, when UE is all restarted timer restart this in each timing time of restarting timer, then the deexcitation moment of CC2 is the moment of restarting any one time-out in timer or the inactive timer of DRX.Suppose that CC3 does not receive data in the timing time of restarting type timer always, then UE is when the timing time of restarting type timer arrives, and can carry out deexcitation process to this CC3.For the processing procedure of CC4 and said process similar, repeat no more.

Therefore, in this implementation, UE can start respectively for the carrier wave after activation restarts type timer, if this carrier wave does not receive any data in the timing time of restarting type timer, then UE can carry out deexcitation process to this carrier wave, if this carrier wave receives data in the timing time of restarting type timer, then UE can be restarted this and be restarted type timer, only when restarting any one timer expired in type timer or the inactive timer of DRX, then deexcitation process is carried out to this carrier wave.Therefore, this implementation can reduce the power loss of UE, and, for not having the carrier wave of transfer of data and receive the carrier wave of data in the timing time of restarting type timer in the timing time of restarting type timer, its deexcitation moment can change flexibly according to the data dispatch situation on this carrier wave.

Mode four can comprise:

1) after carrier wave enters state of activation, type timer is restarted for all carrier waves start one;

3) if all carrier waves all do not receive data in the timing time of restarting type timer, then deexcitation process is carried out to all carrier waves; If any one carrier wave receives data in the timing time of restarting type timer in all carrier waves, type timer is restarted described in then restarting, and when in all carrier waves, any one carrier wave receives data again, type timer is restarted described in restarting, when described restart type timer or DRX inactive timer time time-out time, deexcitation process is carried out to described carrier wave.

In this implementation, UE is that all carrier waves after activating start one and restart type timer, and namely this restarts type timer once start, and when in all carrier waves, any one carrier wave receives data, UE will be restarted type timer and restarts this.

For example, suppose that CC1 is main carrier, then, when CC1 receives data, CC2 ~ CC4 is activated, and now UE can restart type timer for CC2 ~ CC4 starts one.Then in CC2 ~ CC4 any one carrier wave when receiving data, UE can be restarted this and be restarted type timer, make to restart timer and re-start Clocked operation, until this restart in timer and the inactive timer of DRX have one overtime time, namely UE carries out deexcitation process to all carrier waves.When not presetting main carrier, CC1 ~ CC4 all can adopt above-mentioned deexcitation process.

Therefore, in this implementation, for all carrier waves after activation, UE can safeguard that restarts a type timer, if receive data without any a carrier wave in the timing time of restarting type timer, then UE can carry out deexcitation process to all carrier waves, if there is a carrier wave to receive data in the timing time of restarting type timer, then UE can be restarted this and be restarted type timer, only when restarting any one timer expired in type timer or the inactive timer of DRX, then deexcitation process is carried out to this carrier wave.Therefore, this implementation can reduce the power loss of UE.

Mode five can comprise:

1) after carrier wave enters state of activation, non-ly restart type timer for each carrier wave in all carrier waves starts respectively, and common restart type timer for all carrier waves arrange one;

3) if described carrier wave does not receive data in respective non-timing time of restarting type timer, then deexcitation process is carried out to the non-main carrier not receiving data; If all carrier waves all do not receive data after restarting type timer initiation time-out, then deexcitation process is carried out to all carrier waves; If after all carrier waves separately non-restarts type timer initiation, described non-restart type timer expired before on arbitrary carrier wave first time receive data time, restart type timer described in then starting, and stop the non-Clocked operation of restarting type timer corresponding with the carrier wave receiving data; Described restart type timer initiation after, restart type timer restart described when arbitrary carrier wave receives data; And after restarting type timer initiation, non-restart after type timer receives data or timing time-out on the carrier wave corresponding with it stop Clocked operation, type timer expired is restarted the non-of correspondence, or what all carrier waves shared restarts type timer expired, or during the inactive timer expired of DRX, deexcitation process is carried out to this carrier wave

For example, suppose that CC1 is main carrier, then, when CC1 receives data, CC2 ~ CC4 is activated, and now UE non-ly can restart type timer for CC2 ~ CC4 starts respectively.Suppose that CC2 have received data in the non-timing time of restarting type timer corresponding with it, then UE will stop the non-Clocked operation of restarting type timer corresponding with CC2, and type timer is restarted in startup, and UE is that CC2 ~ CC4 safeguards that restarts a type timer jointly.If CC2 is restarted in the timing time of type timer receive data again at this, then this is restarted type timer and restarts timing, if CC3 have received data in the non-timing time of restarting type timer corresponding with it, then UE also will stop the non-Clocked operation of restarting type timer corresponding with CC3, and restarts this and restart type timer.Therefore, in this implementation, when on this CC2 ~ CC4, first time receives data to UE, this is restarted type timer and will be activated, when follow-up CC2 ~ CC4 receives data at every turn, this is restarted type timer and all can be restarted, until CC2 ~ CC4 does not all have data receiver, and when restarting any one time-out in type timer or the inactive timer of DRX, just deexcitation process is carried out to all carrier waves.For the situation not presetting main carrier, the deexcitation process of CC1 ~ CC4 can adopt the processing mode of CC2 ~ CC4, repeats no more.

Therefore, in this implementation, UE can start non-type timer of restarting respectively for the carrier wave after activation, if this carrier wave does not receive any data in non-timing time of restarting type timer, then UE can carry out deexcitation process to this carrier wave, if this carrier wave receives data in non-timing time of restarting type timer, then UE restart jointly safeguard for all carrier waves restart type timer, only when restarting any one timer expired in type timer or the inactive timer of DRX, then deexcitation process is carried out to all carrier waves.Therefore, this implementation can reduce the power loss of UE, and, for the situation not having transfer of data in non-timing time of restarting type timer, or in non-timing time of restarting type timer, receive data and all carrier waves all do not receive the situation of data and in non-timing time of restarting type timer, receive data and any one carrier wave receives the situation of data in the timing time of restarting type timer started in the timing time of restarting type timer of restarting, its deexcitation moment can change flexibly according to the data dispatch situation on this carrier wave.

It should be noted that, above-mentioned each implementation does not all limit the active mode of each carrier wave, those skilled in the art can adopt any one active mode of the prior art to process, above-mentioned each implementation is only after carrier activation, how to carry out deexcitation process according to the data dispatch situation on each carrier wave.

Fig. 2 is the flow chart of another embodiment of method for handling carriers of the present invention, and as shown in Figure 2, the method for the present embodiment can comprise:

Step 201, receiver media access control (MediaAccessControl, hereinafter referred to as: MAC) layer expanded signalling, obtain the carrier identification and corresponding operative position that comprise in described MAC layer expanded signalling, described operative position is used for expression and activates or deactivating operation carrier wave.

For example, UE can receiving mac layer expanded signalling, such as MACCE expanded signalling, carrier identification and the operative position corresponding with this carrier identification can be comprised in this expanded signalling, wherein, operative position can indicate the UE pair of carrier wave corresponding with corresponding carrier identification to activate or deexcitation process.

Particularly, the present embodiment can be expanded MACCE, thus adopts the MACCE after expansion to carry out bitmap instruction to carrier wave.For unactivated carrier wave, the carrier identification comprised in MACCE expanded signalling i.e. carrier wave unactivated with this is corresponding, and corresponding operative position is instruction UE and carries out activation manipulation to this carrier wave.For the carrier wave activated, the carrier wave that namely carrier identification comprised in MACCE expanded signalling has activated with this is corresponding, and corresponding operative position is instruction UE and carries out deexcitation process to this carrier wave activated.

It should be noted that, the present embodiment also can adopt existing MACCE signaling, such as, MACCE signaling under R8 agreement.When UE receives this MACCE signaling, can activate or deexcitation all carrier waves simultaneously, or when setting main carrier, all non-main carriers be activated or deexcitation.

Step 202, the carrier processing corresponding with described operative position is carried out to the carrier wave corresponding with described carrier identification operate.

After UE receives this MAC layer expanded signalling, the corresponding carrier processing in pre-operation position can be carried out to the carrier wave corresponding with carrier identification and operate.Such as, the carrier identification comprised in MACCE expanded signalling is K1, and its corresponding operative position is 0, represents deactivating operation, then UE can carry out deexcitation process to the carrier wave corresponding with K1.The carrier identification comprised in MACCE expanded signalling is K2, and its corresponding operative position is 1, represents activation manipulation, then UE can carry out activation process to the carrier wave corresponding with K2.

Facing to the otherness of the time of UE receiving mac layer expanded signalling, UE can activate or deactivating operation carrier wave in the different moment, thus controls activation or the deactivation status of carrier wave.

The present embodiment adopts MAC layer expanded signalling, bitmap instruction is carried out to the activation of carrier wave or deactivating operation, thus UE can be made to activate neatly or deactivating operation carrier wave according to this MAC layer expanded signalling, and carrier wave can not be made to be in state of activation, thus reduce the power loss of UE.

Further, in the carrier identification that this MAC layer expanded signalling comprises, can be the Frequency Identification of carrier wave from low to high or from high frequency to low frequency, also can be the numbering of carrier wave, thus make UE can carry out one by one activating or deexcitation process according to the different frequency of carrier wave or different numbering, therefore, this operation more for convenience.

Fig. 3 is the flow chart of another embodiment of method for handling carriers of the present invention, and as shown in Figure 3, the method for the present embodiment can comprise:

Step 301, when on main carrier first time receive data time, activation is carried out to the non-main carrier of the first kind identical with the type of described main carrier and processes.

For example, UE first time when receiving data on main carrier, can the first kind identical with the type of this main carrier be carried out activation and processed by non-main carrier.

Particularly, carrier type can comprise PDCCH and PDSCH, if the main carrier preset is a certain PDCCH carrier wave, then after UE receives data on this PDCCH main carrier, can carry out activation process to the non-main carrier of other PDCCH.If the main carrier preset is a certain PDSCH carrier wave, then after UE receives data on this PDSCH main carrier, activation process can be carried out to the non-main carrier of other PDSCH.

Step 302, when arbitrary carrier wave in the non-main carrier of the first kind upon activation receives data, to the non-main carrier of Equations of The Second Kind carry out activation process.

For the situation that the main carrier preset is PDCCH carrier wave, in step 301, the non-main carrier of PDCCH in all non-main carriers is all activated, and the non-main carrier of PDCCH after these activation all can carry out data dispatch.When having the non-main carrier of any one PDCCH to receive data in the non-main carrier of these PDCCH after activating, then the non-main carrier of remaining PDSCH in all non-main carriers can be carried out activation process by UE.

For the situation that the main carrier preset is PDSCH carrier wave, in step 301, the non-main carrier of PDSCH in all non-main carriers is all activated, and the non-main carrier of PDSCH after these activation all can carry out data dispatch.When having the non-main carrier of any one PDSCH to receive data in the non-main carrier of these PDSCH after activating, then the non-main carrier of remaining PDCCH in all non-main carriers can be carried out activation process by UE.

The required carrier wave activating process can be divided into main carrier and non-main carrier by the present embodiment, for non-main carrier, the non-main carrier of the first kind identical with main carrier type and the non-main carrier of Equations of The Second Kind can be divided into again, when UE receives data on main carrier, UE can carry out activation to the non-main carrier of the first kind identical with group carrier type and process, when only having UE to receive data on the non-main carrier of the first kind, again by Equations of The Second Kind non-master carrier activation, therefore, the present embodiment can carry out activation process to carrier wave stage by stage, in activation processing procedure, the dispatch situation on different carrier can be taken into full account, and activation process can not be carried out to all carrier waves simultaneously, therefore, reduce the power loss of UE, and, relative to prior art, its active mode is comparatively flexible.

Fig. 4 is the flow chart of another embodiment of method for handling carriers of the present invention, and as shown in Figure 4, the method for the present embodiment can comprise:

Step 401, receive on main carrier base station send across carrier dispatching instruction, described across carrier dispatching instruction for dispatching the non-main carrier of the physical downlink control channel PDCCH be activated.

For example, the present embodiment can preset a main carrier, and data dispatch can be carried out in base station on this main carrier.When base station needs to carry out data dispatch on some non-main carriers, this base station can send to UE and indicate across carrier dispatching on this main carrier.In the present embodiment, UE can receive indicating across carrier dispatching of base station transmission on main carrier.In the present embodiment, this main carrier can be PDCCH carrier wave, also can be PDSCH carrier wave.Should across carrier dispatching instruction for dispatching the non-main carrier of the PDCCH be activated, namely base station sends for dispatching indicating across carrier dispatching of the non-main carrier of PDCCH on main carrier.

Step 402, according to described across carrier dispatching instruction, the non-main carrier of described PDCCH carries out PDCCH blind check process.

In the prior art, if non-main carrier is configured to PDSCH, then PDCCH blind Detecting need not be carried out on the non-main carrier of this PDSCH, if not main carrier is configured to PDCCH, then UE needs carrying out blind Detecting to the non-main carrier of this PDCCH always, thus obtains Downlink Control Information etc.And in the non-main carrier of configuration, when the quantity of PDCCH is a lot, the power expended when UE carries out blind Detecting is sizable.

Therefore, in the present embodiment, the first time data dispatch of the non-main carrier of each PDCCH can have been indicated across carrier dispatching by being somebody's turn to do by main carrier, when UE receive that base station sends on main carrier indicate across carrier dispatching time, UE can carry out blind Detecting across carrier dispatching instruction to the non-main carrier of PDCCH according to this.And before this, this PDCCH is non-, and main carrier receives only data and does not carry out blind Detecting.

In specific implementation process, should across the identification information that can carry the non-main carrier of PDCCH needing scheduling in carrier dispatching instruction, thus make UE only carry out blind check process for the non-main carrier of the PDCCH that this identification information is corresponding, and the non-main carrier of other PDCCH still only receives data, and do not carry out blind check process.Should across the identification information that also can not carry the non-main carrier of any PDCCH in carrier dispatching instruction, should across carrier dispatching instruction only as a Trigger message, once UE receives this across carrier dispatching instruction on main carrier, namely UE carries out blind check process to the non-main carrier of all PDCCH.

In the present embodiment, when the PDCCH as non-main carrier only receives and indicates across carrier dispatching, UE starts to carry out blind Detecting to this PDCCH again, and need not carry out blind Detecting to this PDCCH always, thus reduces the power loss of UE.

Fig. 5 is the flow chart of a method for handling carriers of the present invention also embodiment, and as shown in Figure 5, the method for the present embodiment can comprise:

Step 501, on the carrier wave being in state of activation, receive the Indication message that base station sends, described Indication message comprises the identification information of carrier wave of needs activation.

For example, UE can receive the Indication message that base station sends on the carrier wave being in state of activation.

Particularly, in the prior art, for independent DRX (hereinafter referred to as: IndependentDRX) mechanism, InactivityTimer due to each carrier wave needs each self-starting, and the time possibility that each carrier wave is in state of activation is different, if therefore when one of them carrier wave is in state of activation, and other carrier waves are not when being in state of activation, base station, such as eNB can only dispatch the carrier wave being in state of activation, and only after the OnDurationTimer of other carrier waves starts, other carrier waves could be dispatched.Therefore, in the prior art, because each carrier wave needs its respective InactivityTimer of independent maintenance, so base station is when dispatching these carrier waves, its dispatching flexibility is restricted.

In the present embodiment, base station can send Indication message to UE on the carrier wave being in state of activation, can comprise the identification information of the carrier wave that needs activate in this Indication message, this identification information can be the numbering of this carrier wave, also can be the Frequency Identification of this carrier wave.

Step 502, activation is carried out to the carrier wave corresponding with described identification information process.

UE according to this identification information, can carry out activation to the carrier wave corresponding with this identification information and processes, thus makes base station the carrier wave after UE activates can carry out data dispatch.

For example, when carrier wave CC1 is in state of activation, and when CC2 is in unactivated state, base station needs to dispatch CC2, then base station can send an Indication message on CC1, and notice UE starts the InactivityTimer of CC2, thus makes CC2 enter state of activation.

It should be noted that, in the present embodiment, this Indication message can be special PDCCH form, can, by using the particular value in existing PDCCH form, can also be also a MACControlElement.And one or more carrier wave being in unactivated state can be indicated in this Indication message to start InactivityTimer, thus enter state of activation, the schedule information of wait-receiving mode base station simultaneously.

In the present embodiment, base station can send Indication message on the carrier wave activated, need the carrier wave being in unactivated state of scheduling to carry out activation process by this Indication message instruction UE to base station, thus make base station carrier wave upon activation can carry out data dispatch.Therefore, in the present embodiment, any carrier wave can be dispatched neatly by Indication message in base station.

Fig. 6 is the flow chart of method for handling carriers of the present invention another embodiment again, and as shown in Figure 6, the method for the present embodiment can comprise:

Step 601, on main carrier, receive data, and semi-persistent scheduling is configured on main carrier.

For example, main carrier can be in state of activation in DRX cycle always, and therefore data dispatch can be carried out in base station on this main carrier, and UE can receive the data of base station scheduling on this main carrier.

If the moment that step 602 first time on described main carrier receives data is the moment that semi-static data is dispatched, then when once receiving data on described main carrier, activation process is carried out to non-main carrier.

UE can judge whether the moment receiving data on this main carrier is for the first time the moment that semi-static data is dispatched.The moment of so-called semi-static data scheduling, the data periodically can dispatched on the main carrier activated for base station.If the moment that UE judges to receive for the first time data on main carrier is the moment that semi-static data is dispatched, then now UE does not carry out activation process to any non-main carrier, but waits for when upper once main carrier receives data again, then carries out activation process to non-main carrier.

Further, if the moment that UE judges to receive these data is not the moment that static data is dispatched, then UE can carry out activation process to described non-main carrier.

In the present embodiment, UE can by judging on main carrier that whether moment that first time receives data is the activationary time of semi-static data scheduling controlling non-main carrier constantly, thus activation process can be carried out to non-main carrier neatly, and after main carrier receives data, namely can not carry out activation process to non-main carrier by UE, therefore, when the data that the present embodiment can receive at main carrier first are semi-static data, reduce the activationary time of non-main carrier, thus realize the effect reducing power loss.

Fig. 7 is the flow chart that method for handling carriers of the present invention goes back again an embodiment, and as shown in Figure 7, the method for the present embodiment can comprise:

Step 701, before semi-persistent scheduling n frame, determine to need the state information of the carrier wave receiving semi-static scheduling data, wherein n≤4.

Specifically, UE can know the cycle of semi-persistent scheduling in advance.N frame before semi-persistent scheduling, UE can pre-determine the state information needing the carrier wave receiving semi-static scheduling data, thus can determine whether the carrier wave needing to receive semi-static scheduling data can receive this semi-static scheduling data.

If the state information of the described carrier wave of step 702 is deactivation status, then activation process is carried out to described carrier wave, receive described semi-static scheduling data with the carrier wave after making activation process.

If UE determines that the carrier wave needing to receive semi-static scheduling data is in state of activation, then UE can not carry out any operation, and on this carrier wave wait-receiving mode semi-static scheduling data, if UE determines that the carrier wave needing to receive semi-static scheduling data is in deactivation status, then UE can carry out activation process to this carrier wave in advance, thus ensureing the semi-persistent scheduling moment, UE carrier wave upon activation can receive semi-static scheduling data.

It should be noted that, in order to ensure in the semi-persistent scheduling moment, corresponding carrier wave is necessarily in state of activation, and those skilled in the art can as required, the suitably size of adjustment n, if the value of n is larger, then activate process more reliable, but the time that carrier wave is in state of activation also can be longer, the power loss of UE will be more, therefore, those skilled in the art can weigh the value of indices to n and adjust.

In the present embodiment, semi-persistent scheduling can be configured on any carrier wave, therefore the state that the UE carrier wave that in advance some frames can be adopted to determine to need to carry out semi-persistent scheduling is current activates or deexcitation, if deactivation status, then carries out to this carrier wave activations and process.The present embodiment, can carry out activation process to carrier wave neatly according to the time of semi-persistent scheduling, and carrier wave need not be made always to be in state of activation with wait-receiving mode semi-static scheduling data, thus shorten the activationary time of carrier wave, reduce the power loss of UE.

Comprehensive above-mentioned all embodiments are known, and the technical scheme of the embodiment of the present invention proposes new processing method for the deexcitation process of the process after the activation process of carrier wave, non-master carrier activation and carrier wave respectively.Under carrier aggregation scene, any one method above-mentioned can be combined with prior art by the embodiment of the present invention, or is combined by said method.Below first to the optional manner activating process, the optional manner of the optional manner of the process after non-master carrier activation and the deexcitation process of carrier wave is non-to be enumerated respectively, is then described various association schemes.

One, the possibility of process is activated

1) scheme that in prior art, all carrier waves activate simultaneously;

2) implicit expression of the prior art activates scheme: main carrier is in state of activation in DRX cycle always, when first time receives data to UE on main carrier, activates all non-main carriers;

3) display that the embodiment of the present invention provides activates scheme, the scheme of concrete scheme embodiment shown in Figure 2;

4) what the embodiment of the present invention provided divides Class Activation scheme, the scheme of concrete scheme embodiment shown in Figure 3;

5) the activation scheme as shown in Figure 6 that provides of the embodiment of the present invention;

6) the activation scheme as shown in Figure 7 that provides of the embodiment of the present invention.

Two, the energy-efficient treatment scheme after non-main carrier PDCCH activation, the scheme of embodiment specifically shown in Figure 4.

Three, the possibility of deexcitation process

1) in prior art when DTX end cycle, deexcitation process is carried out to all carrier waves.

2) above-mentioned embodiment illustrated in fig. 1 in deexcitation processing mode one;

3) above-mentioned embodiment illustrated in fig. 1 in deexcitation processing mode two;

4) above-mentioned embodiment illustrated in fig. 1 in deexcitation processing mode three;

5) above-mentioned embodiment illustrated in fig. 1 in deexcitation processing mode four;

6) above-mentioned embodiment illustrated in fig. 1 in deexcitation processing mode five;

7) above-mentioned embodiment illustrated in fig. 3 in display deexcitation processing scheme.

Therefore, in the overall plan that carrier wave is processed, activate in processing mode 6 schemes that can process in above-mentioned activation scheme of choosing any one kind of them, deexcitation processing mode can be chosen any one kind of them scheme in 7 kinds of schemes of above-mentioned deexcitation process, the activation processing scheme selected and inactive processing scheme are combined, the complete scheme carrying out activating deexcitation to carrier wave can be obtained.Should be noted, for ensureing the new technical scheme that the technical scheme introducing embodiment of the present invention combined provides, if then select the prior art in above-mentioned activation processing scheme, in deexcitation processing scheme, then need the new deexcitation processing scheme selecting the embodiment of the present invention to provide, if select the prior art in above-mentioned deexcitation processing scheme, then activate the new activation processing scheme that processing scheme then needs to select the embodiment of the present invention to provide.For non-main carrier processing scheme upon activation, it is the possibility in complete assembled scheme.When introducing non-main carrier processing scheme upon activation in assembled scheme, then activate processing scheme and inactive processing scheme all can select prior art.And, for simultaneously for UE provides each carrier wave of service, above-mentioned different technical scheme can be adopted to combine.According to foregoing description, those skilled in the art combine activation deexcitation scheme as required.

To select the 2nd in activation process possibility) plant scheme, energy-efficient treatment scheme is adopted to the PDCCH carrier wave of non-main carrier, 2nd is adopted in deexcitation processing scheme to the PDCCH carrier wave of non-main carrier) plant scheme, the 3rd is adopted in deexcitation processing scheme to PDCCH carrier wave) plant scheme.Fig. 8 is the timing diagram of method for handling carriers of the present invention another embodiment again, as shown in Figure 8, main carrier CC1 is in state of activation in DRX cycle always, when UE receives data on main carrier CC1, carrier wave CC2 ~ CC5 is all activated, and UE is CC2 ~ CC5 starts timer respectively, wherein CC2 and CC4 is PDCCH carrier wave, CC3 and CC5 is PDSCH carrier wave, and what therefore UE was that CC2 and CC4 start is non-ly restart type timer, and what start for CC3 and CC5 is restart type timer.When UE receives data on CC2 and CC3, corresponding with CC2 non-ly restart type timer and stop timing, and when DRX cycle technology, also namely at the end of InactivityTimer timing, UE carries out deexcitation process to CC2; And UE pair of the restart type timer corresponding with CC3 carries out reboot operation.In follow-up InactivityTimer timing time, UE only receives data on CC1, and therefore, CC3 is restarted once restarting type timer, and when again arriving timing time, this UE carries out deexcitation process to this CC3.And for CC4 and CC5, due in the timing time of respective timer, UE is and receives any data on CC4 and CC5, therefore, UE when CC4 and CC5 arrives at the timing time of respective timer, carries out deexcitation process to CC4 and CC5 respectively.

Therefore, as seen from Figure 8, UE can start timer respectively for the carrier wave after activation, if this carrier wave does not receive any data in the timing time of timer, then carries out deexcitation process to this carrier wave, therefore, UE can control the activationary time of carrier wave according to the data dispatch situation on different carrier, as shown in Figure 8, each carrier wave is not be all in state of activation in whole DRX cycle, therefore, the present embodiment reduces the power loss of UE.And as shown in Figure 8, the deexcitation time of each carrier wave can be different, and DRX cycle is just deactivated after terminating not have the carrier wave of transfer of data also need not wait until from start to finish, and therefore, the deexcitation mode of the carrier wave of the present embodiment is comparatively flexible always.And, in the present embodiment, as the PDCCH carrier wave of non-main carrier, namely CC2 and CC4 have employed energy-saving scheme, only receive by main carrier CC1 send indicate across carrier dispatching time, UE starts to carry out blind Detecting to this CC2 and CC4 again, and need not carry out blind Detecting to this CC2 and CC4 always, thus reduces the power loss of UE.

In this implementation, UE can start respectively for the carrier wave after activation restarts type timer, if this carrier wave does not receive any data in the timing time of restarting type timer, then UE can carry out deexcitation process to this carrier wave, if this carrier wave receives data in the timing time of restarting type timer, then UE can be restarted this and be restarted type timer, only when restarting any one timer expired in type timer or the inactive timer of DRX, then carries out deexcitation process to this carrier wave.Therefore, this implementation can reduce the power loss of UE, and, for not having the carrier wave of transfer of data and receive the carrier wave of data in the timing time of restarting type timer in the timing time of restarting type timer, its deexcitation moment can change flexibly according to the data dispatch situation on this carrier wave.

Mode four, startup module 11 restart type timer for starting one for all carrier waves; When processing module 12 does not receive data for any one carrier wave in all carrier waves in the timing time of restarting type timer, deexcitation process is carried out to the carrier wave not receiving data, when in all carrier waves, any one carrier wave receives data in the timing time of restarting type timer, type timer is restarted described in restarting, and when in all carrier waves, any one carrier wave receives data again, type timer is restarted described in restarting, when described restart time-out when type timer or noncontinuity receive DRX inactive timer time, deexcitation process is carried out to described carrier wave.

In the manner, start the corresponding of module 11 and the process of processing module 12 and the implementation four of deexcitation processing method, repeat no more herein.

In this implementation, for all carrier waves after activation, UE can safeguard that restarts a type timer, if receive data without any a carrier wave in the timing time of restarting type timer, then UE can carry out deexcitation process to all carrier waves, if there is a carrier wave to receive data in the timing time of restarting type timer, then UE can be restarted this and be restarted type timer, only when restarting any one timer expired in type timer or the inactive timer of DRX, then deexcitation process is carried out to this carrier wave.Therefore, this implementation can reduce the power loss of UE.

Mode five, start module 11 and non-ly restart type timer for starting respectively for each carrier wave in all carrier waves, and be that all carrier waves arrange one and common restart type timer; Processing module 12, for not receiving data at described carrier wave in respective non-timing time of restarting type timer, carries out deexcitation process to the non-main carrier not receiving data; When all carrier waves all do not receive data after restarting type timer initiation time-out, deexcitation process is carried out to all carrier waves; After all carrier waves separately non-restarts type timer initiation, described non-restart type timer expired before on arbitrary carrier wave first time receive data time, restart type timer described in startup, and stop the non-Clocked operation of restarting type timer corresponding with the carrier wave receiving data; Described restart type timer initiation after, restart type timer restart described when arbitrary carrier wave receives data; And after restarting type timer initiation, non-restart after type timer receives data or timing time-out on the carrier wave corresponding with it stop Clocked operation, type timer expired is restarted the non-of correspondence, or what all carrier waves shared restarts type timer expired, or during the inactive timer expired of DRX, deexcitation process is carried out to this carrier wave.
