Description
Technical field
The present invention relates to discontinuous reception (DRX, the Discontinuous Reception) technology in the communications field, relate in particular to discontinuous reception optimization method and device on a kind of multicarrier.
Background technology
Long Term Evolution (LTE) technology of 3G (Third Generation) Moblie partnership (3GPP) has adopted the key technology that improves transmission rate on interface aloft, such as OFDM (OFDM), multiple-input and multiple-output (MIMO), high order modulation etc., target is to reach up 50Mbit/s, the rate requirement of descending 100Mbit/s.In order further to improve transmission rate and other performance, 3GPP determines that senior Long Term Evolution (LTE-A) is as the follow-up enhancing version of LTE, multi-carrier polymerizing, via node, collaborative multipoint reception/technology such as transmitting have been adopted, target is to reach up 500Mbit/s, the rate requirement of descending 1Gbit/s.Wherein, carrier aggregation is to improve the main means of transmission rate request.So-called carrier aggregation, refer to that subscriber equipment (UE) can receive simultaneously/send data on a plurality of component carriers, can there is in the different numbers of descending/up configuration the component carrier of different bandwidth, corresponding one of each component carrier mixes automatic repeat request (HARQ) media access control layer (MAC) entity, and all HARQ MAC entities are by dispatch/priority treatment MAC(Scheduling/priority MAC) entity control.On component carrier, there is an independent Physical Downlink Control Channel (PDCCH) to indicate the resource on this component carrier or other component carrier to distribute.Network can be distributed in business datum and on each component carrier, transmit to improve transmission rate.Fig. 1 is the structural representation of carrier aggregation; business datum is through PDCP (PDCP; Packet data convergence protocol) entity and wireless link are controlled (RLC; Radio link control) after entity; by scheduling/priority treatment MAC entity partitioning, give corresponding HARQ MAC entity; after HARQ MAC entity handles, submit to corresponding component carrier; wherein PDCP entity is encrypted, compresses/integrity protection business datum, and RLC entity carries out dividing processing to the data through PDCP entity handles according to Radio Resource.
DRX technology is the technology that UE is used for saving electric energy, and basic principle is: the discontinuous monitoring of UE PDCCH channel, reduces the electric energy loss of associated components.DRX has carried out standard in LTE R8, and its configuration mechanism is as follows: at UE, in Radio Resource, control under idle (RRC IDLE) state, the DRX parameter configuration of UE is provided by system information, that is, under IDLE state, the DRX parameter of UE is common configuration; At RRC, connect under (RRC Connected) state, the DRX parameter configuration of UE is provided by dedicated control signaling, that is, when UE is successfully linked into after network, the specific DRX parameter of network configuration UE.DRX parameter comprises: DRX cycle (DRX cycle), comprise long DRX cycle (Long DRX-Cycle), short DRX cycle (Short DRX-Cycle), DRX start offset (DRX Start Offset), and some timers below, comprising:
Monitor duration timer (On Duration Timer): stipulated to monitor when DRX cycle starts continuous PDCCH number of sub frames.
DRX non-active timer (DRX-Inactivity Timer): UE monitors continuous PDCCH number of sub frames after successfully decoding and being designated as the PDCCH of descending/uplink user data initial transmission, namely refer to that UE is after having received the initial transmission of PDCCH indication, the activity time of prolongation (Active Time).
MAC-contention solves timer (MAC-Contention Resolution Timer): in random access procedure, after MSG3 sends, UE monitors continuous PDCCH number of sub frames.
DRX retransmission timer (DRX-Retransmission Timer): UE monitors continuous PDCCH number of sub frames while having started to expect descending re-transmission.
The time of UE is divided into DRX parameter configuration the most at last: monitor the activity time (Active Time) of PDCCH and do not monitor the inactive time (Inactive Time) of PDCCH.Wherein, the activity time comprises: after monitoring the time, the UE that wait for uplink grant (UL grant) after duration timer, DRX non-active timer and DRX retransmission timer time, the UE when operation sends dispatch request (SR) and retransmitting/send MSG3, MAC-contention solves time that the UL to be allocated such as the time of waiting for PDCCH after MSG2 after (non-competing access) of having received timer running time, UE, UE authorize etc.The DRX mechanism of LTE R8 is also closely connected with other processes that are arranged in MAC layer: for up, UE completes after random access, to network, send SR request scheduling, UE is in activity time state, network sends the first UL of biography to UE and authorizes, UE receives that rear startup DRX non-active timer is to monitor follow-up possible PDCCH, after treated time delay, carry out uplink (UL transmission), when treated again, delay in certain regulation subframe confirmation of receipt/non-confirmation (ACK/NACK), and monitor UL and authorize, if receive NACK, but do not have UL to authorize, so the delivery time in next this process is carried out to non-self-adapting re-transmission, for descending, UE receives downstream grants (DL assignment), starts HARQ timer two-way time (RTT timer), if HARQ is when two-way time, timer expired, do not complete decoding, so startup DRX retransmission timer is completed to re-transmission to monitor PDCCH.In addition, when receiving component carrier DRX MAC command control unit (DRX MAC Command CE), by UE change current short/long period type, cancel the active state of current DRX cycle simultaneously.
To sum up, although the angle from single component carrier, these mechanism are applicable equally on component carrier above, but due to the component carrier separate configurations on LTE-A PDCCH channel, for uplink authorization or downstream grants, and PDCCH can comprise a carrier identification, to distribute the resource of this component carrier and other component carriers, therefore LTE-A need to introduce some new DRX mechanism and is beneficial to go out to send from whole angle be optimized, and improves the performance of UE.Current scheme is that component carrier is divided into anchor carrier and non-anchor carrier, and anchor carrier has complete DRX configuration, and as the main method of monitoring PDCCH, non-anchor carrier is active sniffing PDCCH not, when anchor carrier is notified, then monitors PDCCH.Yet because non-anchor carrier does not have fixing DRX cycle, therefore within most of the time, can not send the information such as periodic CQI/PMI/RI and SRS, bring difficulty to the scheduling of resource based on channel quality.
