Description
Technical field
The present invention relates to the communications field, relate in particular to the discontinuous reception of a kind of multicarrier (DRX, Discontinuous Reception) method and system.
Background technology
3G (Third Generation) Moblie Long Term Evolution (LTE, Long Term Evolution) system is by the universal land radio access web (E-UTRAN of evolution, Evolved Universal Terrestrial Radio AccessNetwork), the packet-based core networks (EPC) of subscriber equipment (UE, User Equipment), evolution are formed.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 the LTE system, for saving battery/power consumption of UE, it is UE configuration DRX function that eNB may control (RRC) by Radio Resource, with the activity or the behavior of control UE monitoring Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel).Under Radio Resource control connection state, if disposed DRX, UE is allowed to monitor discontinuously PDCCH; Otherwise UE monitors PDCCH continuously.UE during monitoring PDCCH, the resource that can be distributed according to the PDCCH signaling or send data on the shared channel PUSCH receiving data on the Physical Downlink Shared Channel PDSCH or go physically according to pre-configured resource.RRC configuration DRX operates required timer and relevant parameter, comprising: duration timer; The DRX non-active timer; The DRX retransmission timer, except that down mixing self-retransmission request (HARQ) process that receives the Broadcast Control Channel special use, 1 this timer of each descending HARQ process configuration; Long DRX circulation; DRX start offset value.Optionally, also have short cycle timer of DRX and short DRX circulation.Each descending HARQ process except that the descending HARQ process that receives the Broadcast Control Channel special use, also disposes a HARQ Loop Round Trip Time timer.
For describing the DRX behavior of UE, introduced the notion of PDCCH subframe.For the UE of Frequency Division Duplexing (FDD) (FDD, Frequency Divided Duplex) pattern work, the PDCCH subframe can be represented any subframe; For the UE of TDD mode (TDD, Time Divided Duplex) work, the PDCCH subframe only refers to descending sub frame and comprises the special subframe of DwPTS.
Activity time: refer to that UE monitors the time of PDCCH in the PDCCH subframe.
Medium access control competition solves timer and refers to: UE is after the message 3 (Msg3) that has sent random access procedure, and UE should monitor the continuous P DCCH number of sub-frames of PDCCH.
The DRX circulation refers to: the duration follows the periodicity of one section possible inactive time to repeat.
The DRX non-active timer has defined UE continuous PDCCH number of sub-frames after the PDCCH indication of successfully having decoded has the initial uplink (Uplink) of this UE or descending (Downlink) user data transmission.
The DRX retransmission timer, maximum continuous P DCCH number of sub-frames when having defined UE and expecting descending re-transmission at the beginning.
The short cycle timer of DRX has defined UE and has followed the continuous subframes number that short DRX circulates.
HARQ Loop Round Trip Time timer has defined UE and has expected that descending HARQ retransmits minimum number of sub frames before.
Duration timer has defined PDCCH number of sub-frames continuous when the DRX circulation begins.
Fig. 1 shows the basic functional principle of the existing DRX of LTE system: when having disposed the DRX circulation time, the time the when activity time of UE comprises duration timer or DRX non-active timer or DRX retransmission timer or the operation of medium access control competition solution timer; Or go control channel (PUCCH) physically and go up the time that the dispatch request (SR, Scheduling Request) that sends is suspended (Pending), that is: UE sends the time that SR waits for uplink authorization (UL Grant); Or there are data in corresponding harq buffer district, is that the HARQ that is suspended retransmits and distributes the contingent time of uplink authorization; Or after UE successfully receives accidental access response message at the random access guiding of explicit transmission, do not receive the new transmission etc. that the PDCCH indication has the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) at UE as yet.
When having disposed DRX, UE carries out following operation in each subframe:
If use short DRX circulation and satisfy [(SFN * 10)+subframe number] modulo (shortDRX-Cycle)=(drxStartOffset) modulo (shortDRX-Cycle); If perhaps use long DRX circulation and satisfy [(SFN * 10)+subframe number] modulo (longDRX-Cycle)=drxStartOffset,, or be called and periodically carry out DRX and circulate then at corresponding period of sub-frame startup duration timer.For tdd mode, duration timer can start at sub-frame of uplink.Wherein, SFN is the system frame number of record subframe; Subframe number is a number of sub frames; ShortDRX-Cycle is short DRX circulation; DrxStartOffset is the DRX start offset; LongDRX-Cycle is long DRX circulation.
If the data in this subframe in the overtime and soft buffering area of corresponding HARQ process are not successfully decoded, then be corresponding HARQ process initiation DRX retransmission timer.
If receive DRX order medium access control units (DRX command MAC CE), then stop duration timer; Stop the DRX non-active timer.
If it is overtime or receive DRX command MACCE: as if disposed short DRX circulation, then to start or restart the short cycle timer of DRX, use short DRX circulation at this subframe DRX non-active timer; Otherwise use long DRX circulation.
Cycle timer is overtime in this subframe if DRX is short, then uses long DRX circulation.
During the activity time, for the PDCCH subframe, removing for the subframe of half-duplex FDD UE operation with measurement clearance has except the overlapping subframe, and UE need carry out following operation:
Monitor PDCCH.
If the PDCCH indicating downlink sends or in this subframe pre-configured descending distribution is arranged, and then is corresponding HARQ process initiation HARQ Loop Round Trip Time timer; For corresponding HARQ process stops the DRX retransmission timer.
If PDCCH indicating downlink or up new transmission then start or restart the DRX non-active timer.
No matter whether UE is monitoring PDCCH, and when needs received or send the HARQ feedback, UE received or send the HARQ feedback.
In order to satisfy the demand that growing big bandwidth high-speed mobile inserts, third generation partnership project (3GPP, Third Generation Partnership Projects) releases senior Long Term Evolution (LTE-A, Long-Term Evolution advanced) standard.LTE-A adopts series of new techniques that frequency domain, spatial domain are expanded on the LTE basis, to reach purposes such as improving the availability of frequency spectrum, increase power system capacity.Wherein carrier aggregation technology can the two or more component carriers of polymerization to support wideer frequency band, for example, arrive 100MHz and spectrum aggregating.UE is reception/transmission data on one or more component carriers simultaneously, can be configured in descending/different numbers of up gathering and have the component carrier of different bandwidth.Corresponding HARQ entity of each component carrier and transmission channel.Have respectively on each downlink component carrier one independently PDCCH indicate resource allocation on the well-behaved loading gage ripple or the resource allocation on other component carrier, the situation that is divided into downlink resource distribution or uplink authorization has the component carrier index of 3bit to indicate the component carrier identification information on the PDCCH.For the expansion component carrier, may there be PDCCH, its resource allocation and depend on other and have the component carrier of PDCCH to indicate yet.In the LTE-A carrier aggregation, may exist the one-component carrier wave as the Serving cell of UE or be called particular cell, provide safety and Non-Access Stratum mobility information (security and NAS mobility Info), synchronously, functions such as access, system information, paging; Perhaps a plurality of component carriers are 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 (securityand NAS mobility Info), switching, first-selection when inserting at random or particular cell etc. are provided.In a plurality of component carriers, possible configuration backward compatibility component carrier, non-backward compatible component carrier or expansion carrier wave.Wherein the backward compatibility component carrier can provide the UE of LTE system and LTE-A system to insert, and system message, synchronizing channel, random access resource, physical downlink control channel PDCCH etc. are provided.The non-backward compatible component carrier can provide the UE of LTE-A system to insert, system message, synchronizing channel, random access resource etc. are provided, possible configuration or non-configures physical down control channel PDCCH and PDCCH by other component carrier carry out downlink resource and distribute or uplink authorization, and above-mentioned two kinds of component carriers can independently exist.The expansion component carrier generally exists as resource, and some enhancings or expanded function may be provided, and adopts identical or different control signaling format, may provide or not provide system information, possible configuration or non-configures physical down control channel.The PDCCH of UE monitors collection and refers to that UE has disposed the component carrier set of PDCCH, and the component carrier of UE in this set monitored PDCCH according to certain condition.ENB activates by one-component carrier wave that UE disposed or when dispatching other component carrier, indicates by the component carrier index (CI) in the PDCCH signaling.Correspondingly, the upstream components carrier wave also can be supported the carrier aggregation function, disposes one or more ascending physical signal control channel PUCCH; Dispose one or more ascending physical signal shared channel PUSCH.Component carrier also can refer to the upstream components carrier wave of downlink component carrier and its pairing, can be 1 pair 1 or many to the pair relationhip more than 1 or 1 pair.
In the DRX of LTE-A system carrier aggregation scheme, 3GPP has adopted the consistent or common DRX of component carrier or has been called the specific DRX of UE and used identical DRX parameter configuration and identical activity time as the component carrier of all configurations of basic scheme: UE or activation, wherein any component carrier, promptly disposed the component carrier of PDCCH, can other any component carrier of activation.Such scheme also is in the conception stage at present, clearly imperfect as yet concrete solution, for the activation that whether needs to support component carrier and the behavior of UE on the component carrier of deexcitation still under discussion, think tentatively that UE does not monitor PDCCH, do not receive PDSCH on the component carrier of deactivation status, non-receiving system information, may carry out the relevant measurement of mobility, may carry out or not carry out the relevant measurement of channel quality indication (CQI), may close base band and/or radio frequency part module.

Embodiment
Basic thought of the present invention is: for UE disposes a plurality of component carriers, and the identical DRX parameter of a plurality of component carrier configurations.Wherein, at least one component carrier periodically starts duration timer in a plurality of component carriers; Perhaps, when UE periodically started duration timer, at least one component carrier was in the activity time according to duration timer in a plurality of component carriers.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
DRX method and system provided by the invention have carried out improving and specific implementation to the component carrier unanimity or the common DRX scheme that are in the conception stage.
Technical scheme of the present invention mainly comprises following content:
A kind of discontinuous reception method, this method comprises: for UE disposes a plurality of component carriers, the identical DRX parameter of a plurality of component carrier configurations, this method also comprises: at least one component carrier periodically starts duration timer in a plurality of component carriers, when perhaps UE periodically started duration timer, at least one component carrier was in the activity time according to duration timer in a plurality of component carriers.
Here it is to be noted: " a plurality of component carrier " that relate to herein is complete or collected works' notion, and " at least one component carrier " is the notion of subclass; And this subclass and these complete or collected works' relation is: subclass≤complete or collected works.And " component carrier " that do not refer in particular to that relate to herein is general notion, refers to any component carrier in complete or collected works or the subclass, and be perhaps relevant with the scene that is limited.Such as, the deexcitation previous crops is for periodically starting the component carrier of duration timer, when deactivation status was activated, this method also comprised: " component carrier " continues as periodically and starts the component carrier of duration timer or change into the component carrier that does not periodically start duration timer.Here " component carrier " is relevant with the scene of " the deexcitation previous crops is for periodically starting the component carrier of duration timer; be activated from deactivation status ", that is: " component carrier " can be understood as the deexcitation previous crops for periodically starting the component carrier of duration timer.Other places that relate to " component carrier " can be understood with this analogy, and the purpose of doing like this is terse in order to describe, and does not enumerate one by one herein.
Described a plurality of component carrier activates or deexcitation according to the signaling of pre-conditioned or eNB; Described a plurality of component carrier has the identical activity time in state of activation.
Periodically start one or more in the component carrier that the component carrier of duration timer refers to be disposed, and can dynamic change or semi-static variation in the component carrier that is disposed.
The component carrier that periodically starts duration timer can be according to the activation state decision of component carrier in the component carrier that is disposed when dynamic change or semi-static variation; Perhaps can be according to PDCCH signaling or MAC CE or the appointment of RRC signaling; Perhaps can be according to pre-conditioned decision.
Periodically start the component carrier of duration timer, its dynamic change or semi-static variation are to dispose under the situation of appointment by the RRC signaling, until reconfigure other component carriers according to the RRC signaling is when periodically starting duration timer, periodically to start duration timer by other component carriers that reconfigure.Here, at other component carriers, comprise two kinds of situations, a kind ofly be: be this component carrier configuration cycle property startup duration timer, when reconfiguring now, just be this component carrier configuration cycle property startup duration timer before; Another kind is: be this component carrier configuration cycle property startup duration timer before, when reconfiguring now, need configuration attribute before 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 or the like.At this particularize not.
Periodically start the component carrier of duration timer, its dynamic change or semi-static variation are under the situation according to pre-conditioned decision, pre-conditionedly can be the channel wireless condition of component carrier.Described the channel wireless condition within a certain period of time or certain satisfy default threshold value constantly, for example the CQI value of the PDSCH that reports of UE measurement is higher than certain value.
Periodically start the component carrier of duration timer, its dynamic change or semi-static variation are to dispose under the situation of appointment by the RRC signaling, and the identification information of component carrier can dispose in same cell to UE with short DRX circulation or DRX parameters such as long DRX circulation, DRX start offset value.
The component carrier that periodically starts duration timer also can be fixed as some component carriers under the RRC_CONNECTED of UE state.The RRC_CONNECTED state refers to the RRC connection status.
When the component carrier that periodically starts duration timer is fixed as the one-component carrier wave, can be fixed as particular cell, is other component carrier until this particular cell by reprovision, that is to say, component carrier can be bound mutually with particular cell, when reshuffling particular cell, the component carrier that can bind with this configuration change and the bind properties of particular cell.At particular cell, with mention in the background technology the same, reaffirm down again that here in the LTE-A carrier aggregation, may have the Serving cell of one-component carrier wave as UE, this Serving cell can be called particular cell, does not give unnecessary details.
The component carrier that periodically starts duration timer is in state of activation; This component carrier is in deactivation status after by deexcitation, no longer periodically starts duration timer.
Each TTI has at least the one-component carrier wave to be in state of activation, periodically starts duration timer.
Before the described deexcitation for the component carrier that periodically starts duration timer when deactivation status is activated, can continue as periodically and start the component carrier of duration timer or change into the component carrier that does not periodically start duration timer.
Before the described deexcitation for the component carrier that periodically do not start duration timer when deactivation status is activated, component carrier continues can change into the component carrier that periodically starts duration timer as component carrier that does not periodically start duration timer or component carrier.
Component carrier is activated the back for periodically starting the component carrier of duration timer from deactivation status, can be in active state or inactive state when activating.
Component carrier is activated the back for periodically not starting the component carrier of duration timer from deactivation status, is in active state when activating.
When component carrier is activated from deactivation status, during from deexcitation to activation can there be certain time of delay, the processing delay of 1ms is for example arranged; Thereby component carrier receives in deactivation status and activates signaling or during according to pre-conditioned activation, need be under the situation of active state, and can be arranged described certain time of delay from the deactivation status to the active state.
Other component carrier except that the component carrier of described periodicity startup 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 long DRX circulation of being disposed or the subframe that short DRX circulates and DRX start offset value is determined, satisfies relation: if use weak point DRX circulation then [(SFN * 10)+subframe number] modulo (shortDRX-Cycle)=(drxStartOffset) modulo (shortDRX-Cycle); If perhaps use long DRX circulation then [(SFN * 10)+subframe number] modulo (longDRX-Cycle)=drxStartOffset.
The signaling of described eNB refers to PDCCH signaling or MAC control unit (MAC CE) or RRC signaling.
When described eNB passes through signaling deexcitation component carrier, guarantee that at least one component carrier is in state of activation, periodically start duration timer.
Component carrier is meant according to pre-conditioned activation:
To being in the component carrier of deactivation status,, activate the described component carrier that is in deactivation status when UE receives PDCCH when indicating the descending distribution of other component carrier or uplink authorization on other is in the component carrier of state of activation; Perhaps on being in the component carrier of state of activation, other receives PDCCH when indicating the descending distribution of well-behaved loading gage ripple or uplink authorization as UE by the component carrier index, activate the described component carrier that is in deactivation status, and described well-behaved loading gage ripple refers to the described component carrier that is in deactivation status; Perhaps when UE receives the new component carrier of RRC signaling configuration, activate the described component carrier that is in deactivation status; Perhaps when UE initiates random access procedure on the described component carrier that is in deactivation status, activate the described component carrier that is in deactivation status; Perhaps UE described be in deactivation status on when initiating SR, activate the described component carrier that is in deactivation status.
Component carrier is meant that according to pre-conditioned deexcitation component carrier is according to its HARQ operational circumstances deexcitation:
DRX duration timer or DRX non-active timer on component carrier are overtime; Perhaps all HARQ processes of component carrier all do not have to retransmit at expectation HARQ; Perhaps all HARQ processes of component carrier all do not have the DRX retransmission timer in operation, that is: not because of the soft buffering area decoding of HARQ failure starts the DRX retransmission timer, perhaps the DRX retransmission timer of all HARQ processes of component carrier is all overtime or stop when its HARQ Loop Round Trip Time timer expiry for all HARQ processes of component carrier; Perhaps 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, have at least the one-component carrier wave to be in state of activation; UE is during according to pre-conditioned deexcitation component carrier, must have more than the one-component carrier wave and be in state of activation, if all other component carriers except that the unique component carrier that is in state of activation have been in deactivation status, then can not the described unique component carrier that is in state of activation of deexcitation.
If a plurality of component carriers are in state of activation, when then wherein arbitrary component carrier is in the activity time, also corresponding prolongation activity time of other component carrier or deexcitation.Time when the described activity time comprises duration timer or DRX non-active timer or DRX retransmission timer or the operation of medium access control competition solution timer; Or go control channel (PUCCH) physically and go up the time that the dispatch request (SR, Scheduling Request) that sends is suspended (Pending), that is: UE sends the time that SR waits for uplink authorization (UL Grant); Or there are data in corresponding harq buffer district, is that the HARQ that is suspended retransmits and distributes the contingent time of uplink authorization; Or after UE successfully receives accidental access response message at the random access guiding of explicit transmission, do not receive the PDCCH indication as yet when the new transmission etc. of the Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) at UE is arranged; Wherein:
When if arbitrary component carrier receives PDCCH indicating downlink or up new transmission, start or restart the DRX non-active timer.
UE sends the time that SR waits for uplink authorization, and only the one-component carrier wave is in the activity time, and other component carrier is in deactivation status or DRX inactive time.
When there are data in the harq buffer district of certain component carrier correspondence, for the HARQ that is suspended retransmits under the situation of distributing the contingent time of uplink authorization, can be in state of activation or activity time by only corresponding component carrier, other component carrier is in deactivation status or DRX inactive time.
