Description
Technical field
The present invention relates to the communications field, particularly relate to the multiple carrier dispatching method in a kind of multicarrier system and device.
Background technology
For providing higher data rate to mobile subscriber, advanced long-term evolution system (Long TermEvolution Advance, be called for short LTE-A) propose carrier aggregation technology (Carrier aggregation, be called for short CA), its objective is subscriber equipment (the User Equipment for having respective capabilities, be called for short UE) larger broadband is provided, improve the peak rate of UE.In LTE, the maximum downstream transmission bandwidth of system support is 20MHz, carrier aggregation the component carrier of two or more (componentcarriers is called for short CC) is aggregating support be greater than 20MHz, the maximum downstream transmission bandwidth being no more than 100MHz.
Due to the burst feature of business, although UE is operated in the bandwidth that flank speed may use at most as many as 5 carrier waves, but in burst gap, the practical business flow of UE is seldom or close to zero, if now UE also continues wait-receiving mode data over a number of carriers, higher power overhead will be caused.In order to extend the operating time of UE, reduce unnecessary battery consumption, the concept of the activation deexcitation of the carrier wave introduced in lte-a system.UE only carries out data receiver on the carrier wave activated, and as the monitoring of PDCCH channel, for temporary transient no carrier wave, do not do PDCCH channel-monitoring, base station by this carrier wave deexcitation, thus can reach the object of power saving.
Single-carrier system, for saving the battery/power consumption of UE, base station can by radio resource control (RRC) for UE configures discontinuous reception (Discontinuous Reception, be called for short DRX) function, for LTE system, activity or the behavior of Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) is monitored for control UE.Under wireless heterogeneous networks connection status, if be configured with DRX, UE is allowed to monitor PDCCH discontinuously; Otherwise UE monitors PDCCH continuously.UE during monitoring PDCCH, the resource can distributed according to PDCCH signaling or receive data according to pre-configured resource on Physical Downlink Shared Channel PDSCH or physically row shared channel PUSCH send data.RRC configures the required timer of DRX operation and relevant parameter, comprising: duration timer (onDurationTimer); DRX non-active timer (drx-InactivityTimer); Medium education contention resolved timer (mac-ContentionResolutionTimer); DRX retransmission timer (drx-RetransmissionTimer), except receiving special down mixing self-retransmission request (HARQ) process of Broadcast Control Channel, each descending HARQ process configuration 1 this timer; Long DRX circulation (longDRX-Cycle); DRX start offset value (drxStartOffset).Optionally, the short cycle timer of DRX (drxShortCycleTimer) and short DRX is also had to circulate (shortDRX-Cycle).Each descending HARQ process, except receiving the special descending HARQ process of Broadcast Control Channel, is also configured with a HARQ Loop Round Trip Time timer (HARQ RTT Timer).
For describing the DRX behavior of UE, introduce the concept of PDCCH subframe.For the UE of Frequency Division Duplexing (FDD) (FDD, Frequency Divided Duplex) work pattern, PDCCH subframe can represent any subframe; For the UE that TDD mode (TDD, Time Divided Duplex) works, PDCCH subframe only refers to descending sub frame and comprises the special subframe of DwPTS.
Activity time (Active Time): refer to that UE monitors the time of PDCCH in PDCCH subframe.Active Time as shown in Figure 1, can be decomposed into several process, and final Active Time has the monitoring PDCCH event of these processes comprehensively to determine.
1) long DRX process: this process is the basic process of DRX.Do not need specific events trigger, configured the parameter of long DRX by RRC, comprise long DRX and circulate, DRX start offset value and duration.UE is meeting the subframe of formula [(SFN*10)+subframe number] modulo (longDRX-Cycle)=drxStartOffset, start onDurationTimer, wherein SFN is radio frames, and subframenumber is subframe numbers.Namely as shown in FIG., UE can take longDRX-Cycle as the cycle, " timing wake up " to carrying out Signal reception, each " waking up " onDurationTimer length, thus reach UE can power saving, the object of the data that may send can be received again in time.
2) short DRX process: compared with long DRX, the cycle of short DRX is shorter, shortDRX-Cycle, UE starts onDurationTimer afterwards, carries out PDCCH monitoring meeting formula [(SFN*10)+subframe number] modulo (shortDRX-Cycle)=(drxStartOffset) modulo (shortDRX-Cycle).Namely the benefit shortening the cycle of DRX can receive the data sent base station timely, and base station does not need to wait a long period could send data to UE, but the harm brought is the power consumption that can increase UE.Open so short DRX process is triggered short DRX process by event in LTE and and only continue for some time.The trigger condition that short DRX process is opened is drx-InactivityTimer time-out or receives the DRX Command sent base station.Namely, data send in a period of time after transmission or under the expection of base station its basic object, and follow-up continuation needs the possibility of transfer of data comparatively large, and UE continues to treat in short DRX process, in order to receiving data timely.But the short DRX duration is controlled by drxShortCycleTimer, namely over time, UE still can enter long DRX process, can reduce power consumption.
3) DRX process is forbidden.This process passes triggering by the head of the upstream or downstream of PDCCH, the length of a continuity drx-InactivityTimer.Namely UE is after generation transfer of data, and the follow-up possibility proceeding data parameters is comparatively large, and UE needs to keep a period of time to monitor base station, in this section of process, do not carry out DRX dormancy.
4) descending re-transmission waiting process.Due to the feature of HARQ procedure, UE is after RTT timer time-out, need to wait for that base station scheduling retransmits, in this process, UE carries out DRX dormancy obviously also can not be managed, so UE can start a retransmission timer, drx-RetransmissionTimer, guarantees that in retransmission processes, UE is in active state always.
5) Conflict solving process.This process is sent by the MSG3 of random access procedure and triggers, when UE carries out Stochastic accessing, when needing to wait for the MSG4 successfully confirmed, enter DRX dormancy obviously also can not manage, so in Conflict solving process, UE needs to remain on active state, until Conflict solving process terminates, this process is limited by mac-ContentionResolutionTimer.
6) SR process.SR process is used for before UE uplink data sending, and request base station is dispatched it.Asking successfully, if do not receive the mandate of base station, UE can continuously send several SR to base station, and in this process, UE needs to keep active state, until success or unsuccessfully cause SRpending end position.
7) uplink retransmission process, in upstream data process of transmitting, UE may send due to data the successful respond unsuccessfully not receiving base station, carries out uplink retransmission.UE needs to keep active state in the process, terminates until retransmit.
8) non-competing Stochastic accessing downlink data is waited for, non-competing Stochastic accessing generally for and triggers UE and obtain uplink synchronous, then can downlink data receiving, after non-competing random process completes, UE needs to keep active, until receive the downstream grants of PDCCH.
So final active time is determined by above 8 processes, wherein 1) and 2) can not work simultaneously, 3) 4) 5) 6) 7) 8) then can with 1) or 2) concurrent, as long as finally have a process need to be in active state, then UE can keep the monitoring of PDCCH in this subframe.Wherein 1) and 2) be DRX process, other belongs to non-DRX process.LTE MAC has taken into account the object of power saving and effective transmission in designing thus.
DRX is still configured according to UE in multi-carrier systems, and namely multiple carrier wave enters activity time or inactive time according to above-mentioned DRX course synchronization simultaneously.Activate deexcitation mechanism then to control for single carrier wave, prior art cannot realize the DRX process synergic work of multi-carrier polymerizing on same UE and this UE.

Embodiment
In order to solve the problem that cannot realize multi-carrier polymerizing and the work of DRX process synergic, The embodiment provides a kind of multiple carrier dispatching method, use the method, can when UE realize carrier aggregation by multicarrier, the activity time of control UE on each carrier wave respectively.
Scheme described in embodiments of the invention does not limit the process activating deexcitation, according to existing disclosed mechanism, base station can be activated carrier wave by explicit signaling or implicit rule, deexcitation can be carried out to carrier wave by explicit signaling or timer, how no matter adopt, the current activation deactivation status (activation status) of unified use is in state of activation on represents current herein, and off represents current and is in deactivation status.
First by reference to the accompanying drawings, embodiments of the invention one are described.
Embodiments of the invention one provide a kind of multiple carrier dispatching method, by activation deactivation status and DRX duration, UE determines whether designated carrier enters the activity time jointly, namely state of activation is at designated carrier, and when UE was in the DRX duration, the designated carrier of UE is in the activity time.When this carrier wave is not in the DRX duration in unactivated state or UE, the designated carrier of UE is in inactive time.
Use the method to complete the flow process of UE activity time control on each carrier wave as shown in Figure 2, comprising:
Step 201, enter the DRX duration;
In this step, judge whether to start the DRX duration according to preset setup rule, be specially expression formula one or expression formula two, as follows:
Expression formula one:
[(SFN*10)+subframe number]modulo(longDRX-Cycle)＝drxStartOffset
Expression formula two:
[(SFN*10)+subframe number]modulo(shortDRX-Cycle)＝(drxStartOffset)modulo(shortDRX-Cycle)
For the situation using longDRX, UE is meeting the subframe of expression formula one, and start onDurationTimer (namely entering the DRX duration), wherein SFN is radio frames, subframenumber is subframe numbers, and longDRX-Cycle is longDRX circulation.
For the situation using shortDRX, UE starts onDurationTimer when meeting expression formula two.OnDurationTimer run duration and so-called DRX duration, UE during this period of time carries out PDCCH monitoring, receives possible signal.
Owing to being configured with the activation status of carrier wave in the embodiment of the present invention, onDurationTimer independently can not represent whether this carrier wave current is in the activity time (active time), it must combine with activation deactivation status, jointly determines.As shown in Figure 3, during T1 subframe, UE judges to meet above-mentioned longDRX or shortDRX formula, starts onDurationTimer, enters DRX start-up time.
Step 202, UE, according to the activation deactivation status of carrier wave and DRX duration, judge whether the activity time entering this carrier wave;
In this step, as shown in Figure 3, activation status due to carrier wave during T1 subframe is still off state, so UE now can not carry out PDCCH reception on this carrier wave, still inactive time is in, until activation status (carrier wave enters activationary time) after T2 transfers the state of on to, UE judges that now onDurationTimer is still in run duration, so UE enters the activity time.
Step 203, UE, after the activation deactivation status of this carrier wave is terminate deexcitation or DRX duration, terminate the activity time of this carrier wave;
In this step, after T3, although activation status is also on state, onDurationTimer time-out, UE still needs to enter inactive time.
In addition, if onDurationTimer is not overtime, but activation status enters off state by state, then UE still enters inactive time.
Below in conjunction with accompanying drawing, embodiments of the invention two are described.
In order to solve the problem that cannot realize multi-carrier polymerizing and the work of DRX process synergic, embodiments provide a kind of multiple carrier dispatching method, the flow process using the multiple carrier dispatching method that provides of the embodiment of the present invention to complete to control each carrier wave activity time as shown in Figure 4, comprising:
Step 401, enter the DRX duration;
In this step, judge whether to start the DRX duration according to preset setup rule, be specially expression formula one or expression formula two, see step 201 in the embodiment of the present invention one.
Step 402, UE, according to the activation deactivation status of carrier wave and DRX duration, judge whether the activity time entering this carrier wave;
In the embodiment of the present invention, under the activation status of UE is the prerequisite of on, if UE enters the DRX time, then this carrier wave enters the activity time.As shown in Figure 5, in the T1 moment, because the activation status of this carrier wave is in off state, although therefore judge to enter the DRX duration according to expression formula one or expression formula two, but because activation status is off state, also do not start onDurationTimer, in the embodiment of the present invention, each CC respectively has an onDurationTimer.For the activity time, appoint and keep original judgment mechanism, namely onDurationTimer start-up time is as the activity time.So T2 to T3 period UE is in inactive time.When arriving T3, UE receives the order of this carrier wave of activation that base station sends, and the activation status arranging this carrier wave is on state, and UE has entered the DRX duration, therefore enters the activity time of this carrier wave, can carry out the reception of the PDCCH on this carrier wave.
Step 403, UE, after the DRX duration terminates, terminate the activity time of this carrier wave;
In this step, after the T4 of onDurationTimer time-out (namely the DRX duration terminates), terminate the activity time of this carrier wave.In this onDurationTimer, even if activation status switches to off state by state, the activity time on this carrier wave also can not terminate.
Below in conjunction with accompanying drawing, embodiments of the invention three are described.
Embodiments of the invention three provide a kind of multiple carrier dispatching method, activation deactivation status and DRX duration determine whether designated carrier enters the activity time jointly, the flow process using the multiple carrier dispatching method that provides of the embodiment of the present invention to complete to control each carrier wave activity time as shown in Figure 6, comprising:
Step 601, enter the DRX duration;
In this step, judge whether to start the DRX duration according to preset setup rule, be specially expression formula one or expression formula two, see step 201 in the embodiment of the present invention one.
Step 602, UE, according to the activation deactivation status of carrier wave and DRX duration, judge whether the activity time entering this carrier wave;
In the embodiment of the present invention, under the activation status of UE is the prerequisite of on, if UE enters the DRX time, then this carrier wave enters the activity time.As shown in Figure 7, in the T1 moment, because the activation status of this carrier wave is in off state, although therefore judge to enter the DRX duration according to expression formula one or expression formula two, but because activation status is off state, also do not start onDurationTimer.For the activity time, appoint and keep original judgment mechanism, namely onDurationTimer start-up time is as the activity time.So T2 to T3 period UE is in inactive time.Until after T3, T3, this carrier wave activation status switch on state by off state, and meet onDurationTimer start condition, UE starts onDurationTimer, enters the DRX duration.In the embodiment of the present invention, the activity time of carrier wave is determined jointly by onDurationTimer and activationstatus, only has onDurationTimer run duration (namely UE is in the DRX duration) and this carrier wave is in state of activation, namely, when activation status is on, carrier wave just enters the activity time.
Step 603, UE, after the DRX duration terminates or carrier wave enters unactivated state, terminate the activity time of this carrier wave;
As shown in Figure 7, UE, in the T4 moment, because the activation status of carrier wave switches to off by, namely switches to unactivated state by state of activation, so this carrier wave enters inactive time.In addition, carrier wave also can enter inactive time after the DRX duration terminates.
It should be noted that, for embodiments of the invention one, two, three, when UE does not configure concrete DRX, (namely UE is always in the activity time, instead of controlled by DRX) time, also can be 1ms for UE configures longDRX-Cycle, onDurationTimer length is the configuration of 1ms, makes UE be in the DRX duration always, also just achieves the compatibility of embodiments of the invention one, embodiment two, embodiment three.
Below in conjunction with accompanying drawing, embodiments of the invention four are described in detail.
Embodiments provide a kind of multiple carrier dispatching method, the activation deexcitation of multicarrier and DRX process time division multiplexing, concrete, be divided into and activate in deexcitation running and activate the outer two parts of deexcitation running.In activation deexcitation running, the activity time of the designated carrier of UE and the activation deactivation status of this carrier wave are consistent.Outside the activation deexcitation duration, UE carries out work according to the existing rule of configuration, if such as UE is configured with DRX, can carry out DRX process, control according to the activity time of DRX duration to each carrier wave of UE.
The multiple carrier dispatching method using embodiment provided by the invention to provide completes the flow process that controls each carrier wave activity time as shown in Figure 8, comprising:
Step 801, startup activate deexcitation running;
In the embodiment of the present invention, the notice that activation deexcitation running starts can use first activation deexcitation signaling, or last activation deexcitation continues first the activation deexcitation signaling triggering after terminating.Can indicate UE after activation deexcitation running starts by this signaling, the activation deactivation status of corresponding carriers switches.Namely, in activation deexcitation running, the state of this carrier wave can also continue to change between activation deexcitation.
Can also start notice signaling by activating deexcitation running, showing instruction or implicit expression regulation in this signaling, to indicate UE after the activation deexcitation running of a designated carrier starts, the activation deactivation status of corresponding carriers switches.
As shown in Figure 9, before T2, UE is in normal DRX process, in the T1 moment, meets onDurationTimer entry condition (concrete entry condition is see step 201 in the embodiment of the present invention one), starts timer, enters the DRX duration.T2 moment UE receives instruction one carrier wave and enters the signaling activating deexcitation running, indicates corresponding carrier wave to enter and activates deexcitation running, and be initially in unactivated state.Activate deexcitation running T3 by T2 to terminate, it starts and terminates to be controlled by explicit signaling, as base station sends the beginning that MAC CE or PDCCH signaling UE activates the deexcitation duration, MAC CE or PDCCH signaling are explicit signaling (or activating deexcitation signaling), end can notify UE by the mode of identical explicit signaling, or determined by activation deexcitation duration timer, from lasting, continue a time span, as 100ms, then UE terminates to activate deexcitation running.The time span of described activation deexcitation running can be predefined, or carries by starting signaling, or high level is configured by semi-static RRC signaling.
Step 802, when the carrier wave of described UE be in activate in deactivation process time, if this carrier wave enters state of activation, then this carrier wave enters the activity time, if this carrier wave switches to unactivated state by state of activation, then this carrier wave enters inactive time;
In this step, according to the activation deactivation status of carrier wave, carrier wave enters inactive time in the T2 moment from the activity time.In activation deexcitation running, the activity time of carrier wave determines by activating deactivation status, and during T3, this carrier wave is activated, and UE is in the activity time on this carrier wave, until T4, till this carrier wave is deactivated.During T4 to T5, UE is in inactive time at this carrier wave.
Step 803, when the carrier wave of described UE is not when activating in deactivation process, if in configuration DRX situation, the DRX duration of this UE terminates, then this carrier wave enters inactive time;
As shown in Figure 9, after T5, UE terminates to activate deexcitation time-continuing process, enters normal DRX process, switches according to the DRX duration between activity time and inactive time.
As shown in Figure 10, can also configure one is the activation deexcitation time-continuing process of deactivation status entirely, keeps UE to be in inactive time at this carrier wave, thus reaches the effect of 0 power consumption.In like manner configure the activation deexcitation time-continuing process that is state of activation entirely, keep UE to be in the activity time at this carrier wave, ensure the continuous reception to bursty data.
For such scheme, when UE does not configure DRX, and this carrier wave is not when activating in deexcitation running, and this carrier wave is in the activity time always.
