Description
Technical field
The present invention relates to the discontinuous reception (DRX of component carrier in the carrier aggregation system, DiscontinuousReception) definite technology of activity time (active time) relates in particular to discontinuous definite method and the device that receives the activity time in a kind of carrier aggregation system.
Background technology
Third generation partner program (3GPP, 3rd Generation Partnership Project) with senior Long Term Evolution plan (LTE-A, LTE-Advanced) system is defined as the follow-up enhancing version of Long Term Evolution plan (LTE, Long TermEvolution).The LTE-A system has adopted technology such as multi-carrier polymerizing, via node, collaborative multiple spot reception/emission, and target is the rate requirement that reaches up 500Mbit/s, descending 1Gbit/s.Wherein, carrier aggregation is to improve the main means of transmission rate request.So-called carrier aggregation, be meant subscriber equipment (UE, User Equipment) reception/transmission data on a plurality of component carriers simultaneously, can have the component carrier of different bandwidth in descending/different numbers of up configuration, corresponding one of each component carrier mixes automatic repeat requests (HARQ, Hybrid Automatic Repeat reQuest) medium access control (MAC, MediaAccess Control) entity, all HARQ MAC entities are controlled by scheduling/priority treatment MAC entity.In addition, can dispose an independent Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) on the component carrier and indicate the resource allocation on well-behaved loading gage ripple or other component carrier.Network can be distributed in business datum and transmit on each component carrier to improve transmission rate.
Discontinuous reception technique (DRX, Discontinuous Reception) is the technology that UE is used for saving electric energy, and according to the associated description of LTE R8 standard, the DRX basic principle is: the discontinuous monitoring of UE PDCCH, and to reduce the electric energy loss of associated components.DRX is at LTE version 8 (R8, Release 8) in carried out standard, its configuration mechanism is as follows: at Radio Resource control (RRC, Radio ResourceControl) under IDLE (free time) state, the DRX parameter configuration of UE realizes by system message, that is to say that the DRX parameter of UE is a common configuration under the IDLE state.Under RRC Connected state, the DRX parameter configuration of UE is notified UE by dedicated control signaling.The DRX parameter comprises: DRX cycle (DRX cycle) comprises long period longDRX-Cycle and short period shortDRX-Cycle, start offset drxStartOffset and following timers:
Continue to monitor timer (onDurationTimer): stipulated PDCCH number of sub frames continuous when DRX cycle begins.
Discontinuous receiving inactive timer (drx-InactivityTimer): UE successfully decodes and monitors continuous PDCCH number of sub frames behind the PDCCH that is designated as descending/uplink user data initial transmission, just refer to UE after the initial transmission of having received the PDCCH indication, the active time time of prolongation.
Medium access control contention solves timer (mac-ContentionResolutionTimer): in the random access procedure, Msg3 sends the continuous subframes number that back UE monitors PDCCH.
Continuous PDCCH number of sub frames when discontinuous retransmission timer (drx-RetransmissionTimer): UE has begun to expect to monitor descending the re-transmission.
Mix automatic repeat requests timer two-way time (HARQ RTT Timer): UE is restarted after receiving downlink command automatically.
The time of UE is divided into activity time (active time) of monitoring PDCCH and the inactive time (non-active time) of not monitoring PDCCH to the DRX parameter configuration the most at last.Wherein, activity time comprises timer ondurationtimer, DRXinactivitytimer and the drx-RetransmissionTimer time when operation, UE sends service dispatching request (SR, Service Request) time of uplink authorization (UL grant) is waited in the back, UE has sent Access Probe (RAP at random, Random access preamble) receiving random access response (Random access Response is waited in the back, RAR) time, macContentionResolutionTimer running time behind the UE repeating transmission/transmission Msg3, UE has received the time of (non-competing access) back wait PDCCH behind the Msg2, the time of UL grant to be allocated such as UE etc.DRX mechanism among the LTE R8 also is closely connected with other processes that are arranged in the MAC layer: for up, after UE finishes and inserts at random, send the SR request scheduling to network, UE is in active time state, network sends new biography UL grant to UE, UE receives that the back starts DRX inactivity timer to monitor follow-up possible PDCCH, carry out uplink (UL transmission) after the treated time delay, delay when treated again in certain regulation subframe and receive (just reply/react and answer) ACK/NACK, and monitoring UL grant, if receive NACK, but do not have UL grant, will carry out non-self-adapting so at the delivery time of next process and retransmit.For descending, after UE receives downstream arrangements (DL assignment), start HARQ RTT timer, if when HARQ RTT timer expires, do not finish decoding, will start drx-RetransmissionTimer so and finish re-transmission with monitoring PDCCH.In addition, when receiving DRX MAC Command CE, UE is changed current short/long period type, cancel the active state of current DRX cycle simultaneously.
Though angle from single component carrier, more than these mechanism suitable equally on component carrier, but since LTE-A on the component carrier separate configurations PDCCH channel, be used for uplink assignment UL grant or descending distribution DL assignment, therefore, LTE-A need improve the performance of UE based on the DRX mechanism of LTE R8.In addition, the carrier aggregation technology of LTE-A has three types for receiver, is respectively discontinuous carrier polymerization and the polymerization of interband discontinuous carrier in continuous carrier polymerization in the band, the band.For continuous carrier polymerization in the band, can adopt single broadband reception device or discrete receiver to receive.For discontinuous carrier polymerization in the band, the polymerization of interband discontinuous carrier, single broadband receiver poor-performing can adopt discrete receiver to receive.For these three types of carrier waves, standard common recognition (baseline) is that each component carrier adopts general DRX scheme at present, the active time time that is described component carrier is identical, and layer 1 (L1) signaling of component carrier can be dispatched other component carrier resource.When component carrier has been received the PDCCH of the first biography of indication, all component carriers will start/restart DRX inactivity timer, and this DRXinactivity timer shares for all component carriers, so all component carriers will be monitored PDCCH.When component carrier is received the UL grant of indication new biography, component carrier will start/restart DRX inactivitytimer, after a fixed response time, carry out the UL transmission, after a fixed response time, will enter active time and carry out the UL transmission, when receiving DRX commandMAC control unit (DRX command MAC CE), stop Onduration timer and DRX inactivity timer.
How to realize the active time mechanism of above-mentioned DRX in the LTE-A system, not corresponding regulation does not have the technical scheme that relates to above-mentioned treatment mechanism at present yet in the related protocol.
