Description
Technical field
The present invention relates to the communications field, particularly relate to a kind of multicarrier discontinuous reception (DRX, DiscontinuousReception) method and system.
Background technology
3G (Third Generation) Moblie Long Term Evolution (LTE, LongTermEvolution) system is by the universal land radio access web (E-UTRAN of evolution, EvolvedUniversalTerrestrialRadioAccessNetwork), packet-based core networks (EPC) composition of subscriber equipment (UE, UserEquipment), evolution.Wherein, E-UTRAN is made up of enhanced base station (eNB), also can be called eNB; UE also can be called terminal; EPC comprises mobile management entity (MME), packet data network gateway (P-GW) and Service Gateway (S-GW).
In LTE system, for saving the battery/power consumption of UE, eNB by wireless heterogeneous networks (RRC) for UE configures DRX function, can monitor activity or the behavior of Physical Downlink Control Channel (PDCCH, PhysicalDownlinkControlChannel) with 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; DRX non-active timer; DRX retransmission timer, 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; DRX start offset value.Optionally, the short cycle timer of DRX and short DRX is also had to circulate.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.
For describing the DRX behavior of UE, introduce the concept of PDCCH subframe.Any subframe can be represented for the UE of Frequency Division Duplexing (FDD) (FDD, FrequencyDividedDuplex) work pattern, PDCCH subframe; Descending sub frame is only referred to for the UE that TDD mode (TDD, TimeDividedDuplex) works, PDCCH subframe and comprises the special subframe of DwPTS.
Activity time: refer to that UE monitors the time of PDCCH in PDCCH subframe.
Medium education contention resolved timer refers to: UE is after have sent the message 3 (Msg3) of random access procedure, and UE should monitor the continuous P DCCH number of sub-frames of PDCCH.
DRX circulation refers to: the duration repeats with the periodicity of one section of possible inactive time.
DRX non-active timer, defines UE continuous print PDCCH number of sub-frames after PDCCH instruction of successfully having decoded has the initial uplink of this UE (Uplink) or descending (Downlink) user data transmission.
DRX retransmission timer, defines maximum continuous P DCCH number of sub-frames when UE expects descending re-transmission at the beginning.
The short cycle timer of DRX, defines the continuous subframes number that UE follows short DRX circulation.
HARQ Loop Round Trip Time timer, define UE expect descending HARQ retransmit before minimum number of sub frames.
Duration timer, defines continuous print PDCCH number of sub-frames when DRX circulation starts.
Fig. 1 shows the basic functional principle of existing LTE system DRX: when being configured with DRX circulation time, and activity time of UE comprises time when duration timer or DRX non-active timer or DRX retransmission timer or medium education contention resolved timer run; Or the dispatch request (SR of the upper transmission of row control channel (PUCCH) physically, SchedulingRequest) be suspended the time of (Pending), that is: UE sends the time that SR waits for uplink authorization (ULGrant); Or there are data in the harq buffer district of correspondence, distribute the uplink authorization contingent time for the HARQ be suspended retransmits; Or after UE successfully receives the accidental access response message for the random access guiding of explicit transmission, not yet receive the new transmission etc. that PDCCH instruction has the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) for UE.
When being configured with DRX, UE performs following operation in each subframe:
If use short DRX to circulate and meet [(SFN × 10)+subframenumber] modulo (shortDRX-Cycle)=(drxStartOffset) modulo (shortDRX-Cycle); If or use long DRX to circulate and meet [(SFN × 10)+subframenumber] modulo (longDRX-Cycle)=drxStartOffset, then start duration timer in corresponding period of sub-frame, or be called that periodicity carries out DRX circulation.For tdd mode, duration timer can start at sub-frame of uplink.Wherein, SFN is the system frame number of record subframe; Subframenumber is number of sub frames; ShortDRX-Cycle is that short DRX circulates; DrxStartOffset is DRX start offset; LongDRX-Cycle is that long DRX circulates.
If overtime in this subframe and in the corresponding soft buffering area of HARQ process data are not successfully decoded, be then corresponding HARQ process initiation DRX retransmission timer.
If receive DRX order medium education unit (DRXcommandMACCE), then stop duration timer; Stop DRX non-active timer.
If in this subframe DRX non-active timer time-out or receive DRXcommandMACCE: circulate if be configured with short DRX, then start or restart the short cycle timer of DRX, use short DRX to circulate; Otherwise use long DRX to circulate.
If the short cycle timer of DRX in this subframe time-out, then uses long DRX to circulate.
During the activity time, for PDCCH subframe, except the subframe operated for half-duplex FDDUE with have except overlapping subframe with measurement clearance, UE needs to perform following operation:
Monitor PDCCH.
If PDCCH indicating downlink sends or has pre-configured descending distribution in this subframe, be then corresponding HARQ process initiation HARQ Loop Round Trip Time timer; For corresponding HARQ process stops DRX retransmission timer.
If PDCCH indicating downlink or up transmission newly, then start or restart DRX non-active timer.
No matter whether UE is at monitoring PDCCH, and when needs receive or send HARQ feedback, UE receives or sends HARQ feedback.
In order to meet the demand of growing large bandwidth high-speed mobile access, third generation partnership project (3GPP, ThirdGenerationPartnershipProjects) senior Long Term Evolution (LTE-A, Long-TermEvolutionadvanced) standard is released.LTE-A adopts series of new techniques to expand frequency domain, spatial domain on LTE basis, improves the availability of frequency spectrum, increases the objects such as power system capacity to reach.Wherein carrier aggregation technology can be polymerized two or more component carrier to support wider frequency band, such as, arrives 100MHz and spectrum aggregating.UE can receive simultaneously/send data on one or more component carriers, can be configured in the component carrier that the different number of descending/up gathering has different bandwidth.The corresponding HARQ entity of each component carrier and transmission channel.In each of the lower row component carrier has respectively one independently PDCCH indicate the Resourse Distribute on this component carrier or the Resourse Distribute on other component carrier, be divided into the situation of downlink resource distribution or uplink authorization, PDCCH have the component carrier index instruction component carrier identification information of 3bit.For expansion component carrier, PDCCH may be there is no, its Resourse Distribute and depend on other and have the component carrier of PDCCH to indicate yet.In LTE-A carrier aggregation, one-component carrier wave may be there is as the Serving cell of UE or be called particular cell, the function such as safety and Non-Access Stratum mobility information (securityandNASmobilityInfo), synchronous, access, system information, paging is provided; Or multiple component carrier is all as the Serving cell of UE, above-mentioned functions is provided, wherein 1 Serving cell can be set to main Serving cell, as witness mark, safety and Non-Access Stratum mobility information (securityandNASmobilityInfo), switching, Stochastic accessing be provided time first-selection or particular cell etc.In multiple component carrier, possible configuration backward compatibility component carrier, non-backward compatible component carrier or expansion carrier wave.Wherein backward compatibility component carrier can provide the UE of LTE system and lte-a system to access, and provides system message, synchronizing channel, random access resource, physical downlink control channel PDCCH etc.Non-backward compatible component carrier can provide the UE of lte-a system to access, system message, synchronizing channel, random access resource etc. are provided, possible configuration or non-configures physical down control channel PDCCH and carry out downlink resource distribution or uplink authorization by the PDCCH of other component carrier, above-mentioned two kinds of component carriers can independently exist.Expansion component carrier generally exists as resource, some may be provided to strengthen or expanded function, adopt identical or different control signal form, may provide or not provide system information, possible configuration or non-configures physical down control channel.The PDCCH monitor set of UE refers to that UE is configured with the component carrier set of PDCCH, and the component carrier of UE in this set monitors PDCCH according to certain condition.The one-component carrier activation that eNB is configured by UE or when dispatching other component carrier, is indicated by the component carrier index (CI) in PDCCH signaling.Correspondingly, upstream components carrier wave also can support carrier aggregation function, configures one or more ascending physical signal control channel PUCCH; Configure one or more ascending physical signal shared channel PUSCH.Component carrier also can refer to downlink component carrier and its pairing upstream components carrier wave, can be 1 to 1 or multipair 1 or 1 to many pair relationhips.
In the DRX scheme of lte-a system carrier aggregation, 3GPP adopts the consistent or common DRX of component carrier or is called that the specific DRX of UE is as basic scheme: the component carrier of all configurations of UE or activation uses identical DRX parameter configuration and identical activity time, wherein any component carrier, namely the component carrier of PDCCH is configured with, can other any component carrier of activation/deactivation.Such scheme is also in the conception stage at present, not yet clearly perfect concrete solution, for the need of supporting the activation/deactivation of component carrier and the behavior of UE on the component carrier of deexcitation still under discussion, tentatively thinking that UE does not monitor PDCCH, do not receive PDSCH on the component carrier of deactivation status, non-receiving system information, the relevant measurement of mobility may be carried out, may carry out or not carry out the relevant measurement of channel quality instruction (CQI), base band and/or radio frequency part module may be closed.

Embodiment
Basic thought of the present invention is: for UE configures multiple component carrier, and multiple component carrier configures identical DRX parameter.Wherein, in multiple component carrier, at least one component carrier periodically starts duration timer; Or when UE periodically starts duration timer, in multiple component carrier, at least one component carrier is in the activity time according to duration timer.
Be described in further detail below in conjunction with the enforcement of accompanying drawing to technical scheme.
DRX method and system provided by the invention, the DRX scheme consistent or common to the component carrier being in the conception stage has carried out improving and specific implementation.
Technical scheme of the present invention mainly comprises following content:
A kind of discontinuous reception method, the method comprises: for UE configures multiple component carrier, multiple component carrier configures identical DRX parameter, the method also comprises: in multiple component carrier, at least one component carrier periodically starts duration timer, or when UE periodically starts duration timer, in multiple component carrier, at least one component carrier is in the activity time according to duration timer.
Here it is to be noted: " the multiple component carrier " that relate to herein is the concept of complete or collected works, " at least one component carrier " is the concept of subset; And the relation of this subset and these complete or collected works is: subset≤complete or collected works.And " component carrier " that do not refer in particular to that relate to is general concept, refer to any component carrier in complete or collected works or subset herein, or relevant to limited scene.Such as, deexcitation previous crops is the component carrier periodically starting duration timer, when being activated from deactivation status, the method also comprises: " component carrier " continues as the component carrier of periodically startup duration timer or change into the component carrier periodically not starting duration timer.Here " component carrier " is relevant with the scene of " deexcitation previous crops is the component carrier periodically starting duration timer; be activated from deactivation status ", that is: " component carrier " can be understood as deexcitation previous crops is the component carrier periodically starting duration timer.The place that other relate to " component carrier " can be understood with this analogy, and the object done like this is terse in order to describe, and does not enumerate herein.
Described multiple component carrier activates or deexcitation according to signaling that is pre-conditioned or eNB; Described multiple component carrier has the identical activity time in state of activation.
It is one or more that the component carrier periodically starting duration timer refers in configured component carrier, and can dynamic change or semi-static change in configured component carrier.
The component carrier periodically starting duration timer, can according to the activation/deactivation Determines of component carrier in configured component carrier when dynamic change or semi-static change; Or can specify according to PDCCH signaling or MACCE or RRC signaling; Or can according to pre-conditioned decision.
Periodically start the component carrier of duration timer, its dynamic change or semi-static change are when being specified by RRC signal deployment, until when reconfiguring other component carriers for periodically starting duration timer according to RRC signaling, periodically start duration timer by other component carriers reconfigured.Here, for other component carriers, comprise two kinds of situations, Yi Zhongshi: be not that this component carrier configuration cycle property starts duration timer, when reconfiguring now, be just that this component carrier configuration cycle property starts duration timer before; Another kind is: before for this component carrier configuration cycle property starts duration timer, when reconfiguring now, configuration attribute before need be changed, such as, this component carrier has been configured to periodically start duration timer before, when reconfiguring now, this component carrier is configured to periodically not start duration timer etc.At this not particularize.
Periodically start the component carrier of duration timer, when its dynamic change or semi-static change are according to pre-conditioned decision, pre-conditioned can be the channel wireless condition of component carrier.Described channel wireless condition within a certain period of time or certain moment meet default threshold value, the CQI value of the PDSCH that such as UE measurement reports is higher than certain value.
Periodically start the component carrier of duration timer, its dynamic change or semi-static change are when being specified by RRC signal deployment, and the identification information of component carrier can configure to UE in same cell with the DRX parameter such as short DRX circulation or long DRX circulation, DRX start offset value.
The component carrier periodically starting duration timer also can be fixed as some component carriers under the RRC_CONNECTED state of UE.RRC_CONNECTED state refers to RRC connection status.
When periodically the component carrier of startup duration timer is fixed as one-component carrier wave, particular cell can be fixed as, until this particular cell is re-equipped as other component carrier, that is, component carrier can be bound mutually with particular cell, when reshuffling particular cell, the component carrier can bound with this configuration change and the bind properties of particular cell.For particular cell, with mention in background technology the same, reaffirm down more here, in LTE-A carrier aggregation, may there is the Serving cell of one-component carrier wave as UE, this Serving cell can be called particular cell, does not repeat.
The component carrier periodically starting duration timer is in state of activation; Be in deactivation status after this component carrier is deactivated, no longer periodically start duration timer.
Each TTI, has at least one-component carrier wave to be in state of activation, periodically starts duration timer.
When component carrier for periodically starting duration timer before described deexcitation being activated from deactivation status, periodicity can being continued as and start the component carrier of duration timer or change into the component carrier periodically not starting duration timer.
When component carrier for periodically not starting duration timer before described deexcitation is activated from deactivation status, component carrier continues can change into as the component carrier or component carrier that periodically do not start duration timer the component carrier periodically starting duration timer.
For periodically starting the component carrier of duration timer after component carrier is activated from deactivation status, active state or inactive state can be in when activating.
For periodically not starting the component carrier of duration timer after component carrier is activated from deactivation status, be in active state when activating.
When component carrier is activated from deactivation status, certain time of delay can be had from when being deactivated to activation, such as, have the processing delay of 1ms; Thus component carrier deactivation status receive activate signaling or according to pre-conditioned activation time, when needing to be in active state, described certain time of delay can be had from deactivation status to active state.
Other component carrier except the component carrier that described periodicity starts duration timer is in state of activation or deactivation status; When these component carriers are in state of activation, be in the activity time until deexcitation always.
Described periodicity starts duration timer and refers to start duration timer according to the configured subframe that long DRX circulates or short DRX circulates and DRX start offset value determines, meets relation: if use short DRX to circulate, [(SFN × 10)+subframenumber] modulo (shortDRX-Cycle)=(drxStartOffset) modulo (shortDRX-Cycle); If or used long DRX to circulate, [(SFN × 10)+subframenumber] modulo (longDRX-Cycle)=drxStartOffset.
The signaling of described eNB refers to PDCCH signaling or MAC balancing boom (MACCE) or RRC signaling.
When described eNB is by signaling deactivation of component carrier, ensure that at least one component carrier is in state of activation, periodically start duration timer.
Component carrier refers to according to pre-conditioned activation:
To the component carrier being in deactivation status, when UE other be in the component carrier of state of activation receives PDCCH indicate descending distribution or the uplink authorization of other component carrier time, be in the component carrier of deactivation status described in activation; Or when UE other be in the component carrier of state of activation receives PDCCH to be indicated descending distribution or the uplink authorization of this component carrier by component carrier index time, be in the component carrier of deactivation status described in activation, and described component carrier refer to described in be in the component carrier of deactivation status; Or when UE receives the new component carrier of RRC signal deployment, described in activation, be in the component carrier of deactivation status; Or when UE during initiating random access procedure, is in the component carrier of deactivation status on the described component carrier being in deactivation status described in activation; Or UE described be in the upper initiation SR of deactivation status time, be in the component carrier of deactivation status described in activation.
According to pre-conditioned deexcitation, component carrier refers to that component carrier is according to its HARQ operation situation deexcitation:
When the DRX duration timer on component carrier or DRX non-active timer time-out; Or all HARQ processes of component carrier all do not have to retransmit at expectation HARQ; Or all HARQ processes of component carrier all do not have DRX retransmission timer in operation, that is: all HARQ processes of component carrier start DRX retransmission timer because decode unsuccessfully in the soft buffering area of HARQ when its HARQ Loop Round Trip Time timer expiry, or all time-out or the stopping of the DRX retransmission timer of all HARQ processes of component carrier; Or the channel load situation of component carrier or channel wireless condition are lower than certain predetermined threshold value; Then component carrier deexcitation.
At each TTI, one-component carrier wave is had at least to be in state of activation; When UE is according to pre-conditioned deactivation of component carrier, more than one component carrier must be had to be in state of activation, if other component carriers all except the unique component carrier being in state of activation are in deactivation status, then can not be in unique component carrier of state of activation described in deexcitation.
If multiple component carrier is in state of activation, then when wherein arbitrary component carrier is in the activity time, other component carrier is corresponding prolongation activity time or deexcitation also.The described activity time comprises time when duration timer or DRX non-active timer or DRX retransmission timer or medium education contention resolved timer run; Or the dispatch request (SR of the upper transmission of row control channel (PUCCH) physically, SchedulingRequest) be suspended the time of (Pending), that is: UE sends the time that SR waits for uplink authorization (ULGrant); Or there are data in the harq buffer district of correspondence, distribute the uplink authorization contingent time for the HARQ be suspended retransmits; Or after UE successfully receives the accidental access response message for the random access guiding of explicit transmission, not yet receive PDCCH instruction when having a new transmission etc. for the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) of UE; Wherein:
If when arbitrary component carrier receives PDCCH indicating downlink or up new transmission, start or restart DRX non-active timer.
UE sends the time that SR waits for uplink authorization, and only can be in the activity time by one-component carrier wave, other component carrier is in deactivation status or DRX inactive time.
There are data in the harq buffer district corresponding when certain component carrier, when the time contingent for the HARQ re-transmission distribution uplink authorization be suspended, only can be in state of activation or activity time by corresponding component carrier, other component carrier is in deactivation status or DRX inactive time.
When after the accidental access response message that UE successfully receives for the random access guiding of explicit transmission, when not yet receiving the new transmission that PDCCH instruction has for the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) of UE, the component carrier of only corresponding receiving random access response message can be in the activity time, other component carrier is in deactivation status or DRX inactive time.
If multiple component carrier is in state of activation, in each subframe, only can start duration timer until deexcitation by one-component carrier cycle, after this component carrier deexcitation, select other one-component carrier cycle to start duration timer until deexcitation.
Whether described eNB with UE is that the component carrier periodically starting duration timer has consistent information to the activation/deactivation state of component carrier, component carrier, between eNB and UE can according to described pre-conditioned judge component carrier described activation/deactivation state, whether periodically start duration timer, or reported by signaling or poll component carrier described activation/deactivation state, whether periodically start duration timer.
In described DRX parameter, for duration timer, each component carrier jointly can use and jointly safeguard a timer; Or use respectively and jointly safeguard respective timer.
