Embodiment

Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.

The technical scheme of various embodiments of the present invention is applicable to the situation of carrying out multicarrier DRX configuration under the CA technology.Be that example describes with the LTE system below, in LTE R8, the DRX technical scheme of UE is to be that UE carries out the DRX configuration by network side configuration network element under the connection status, and the DRX parameter of configuration can comprise following several usually:

DRX cycle, i.e. basic long DRX cycle and optionally short DRX cycle, short DRX cycle is enabled under certain condition and is stopped using behind certain hour;

The side-play amount (drxStartOffset) that first duration timer (on duration timer) and first duration timer are opened, each DRX cycle are waken the back up and are continued to monitor in the determined time range of first duration timer;

Second duration timer (inactivity-timer) will continue monitoring when UE successfully receives before entering sleep after the new transmitting and scheduling PDCCH in the time range of the second duration timer defined;

After certain data block decoding failure, the possible descending re-transmission duration timer (Retrans Timer) that UE waits for.

The monitoring waveform that UE monitors according to the DRX parameter of network configuration unit configuration can be as shown in Figure 1, UE periodically wakes up from sleep state according to long DRX cycle, and the lasting PDCCH that monitors, if during monitoring, successfully do not detect the transmitting and scheduling PDCCH of oneself, then after first duration timer, reenter sleep state; An if new transmitting and scheduling PDCCH who successfully detects oneself, as among Fig. 1 1. shown in, then start second duration timer, changing short DRX cycle simultaneously over to monitors, send respectively at 2. and 3. some place and when receiving PDCCH, just start second duration timer respectively again, and before second duration timer is overtime, continue to monitor PDCCH; If the some time is inscribed the decoded packet data failure that row sends, for example 1. decoding at some place failure is according to mixing automatic repeat requests (Hybrid-ARQ; Hereinafter to be referred as: HARQ) technology is retransmitting lasting monitoring the in duration timer (Retrans Timer) scope afterwards at the descending retransfer scheduling timer of setting (HARQ RTT Timer).When the short DRX cycle of setting number does not constantly receive PDCCH, then change long DRX cycle over to.

UE needs to keep state of activation and is called activationary time (active time) in the descending time unification definition that PDCCH is monitored according to the DRX configuration, and visible activationary time comprises first duration timer, second duration timer and retransmits time timer running time and other time that may be scheduled.Time outside the activationary time is the length of one's sleep, and UE can enter sleep state, stops to monitor.UE carries out state of activation or dormant replacing according to DRX cycle.

Embodiment four

The flow chart of the implementation method of a kind of discontinuous reception configuration that Fig. 5 provides for the embodiment of the invention four, present embodiment can dispose network element by network side and carry out based on above-described embodiment two, and the method for present embodiment comprises the steps:

Step 501, network side configuration network element receive the ability information that UE reports, and obtain configuration reference information call number from ability information;

Step 502, network side configuration network element are inquired about each self-corresponding configuration reference information of at least two CC of UE in the mapping table of this locality according to configuration reference information call number;

In the present embodiment, can a pre-configured mapping table in network side configuration network element and UE, stored the permutation and combination between the various configuration reference informations of CC in the mapping table, for example embody this UE and support several CC, each CC uses information such as which rf chain and frequency range thereof, and each CC shares the information of rf chain, each combination is with a configuration reference information call number sign, UE only need report configuration reference information call number, and network side configuration network element can be inquired about the configuration reference information of knowing each CC voluntarily according to configuration reference information call number.This scheme has reduced the amount of information that UE need report, and can save network transmission resource.

Step 503, network side configuration network element are divided at least one carrier wave set according at least two each self-corresponding configuration reference informations of CC with each CC;

Step 504, network side configuration network element is each carrier wave set configuration DRX parameter, and the DRX parameter of each carrier wave set and the CC in each carrier wave set identified is issued to UE, so that UE monitors simultaneously to the CC of each carrier wave set.

The technical scheme of the various embodiments described above is carried out by network side configuration network element, particularly, can dispose Radio Resource control (the Radio Resource Control that comprises in the network element by network side; Hereinafter to be referred as: RRC) layer or media interviews control (Medium Access Control; Hereinafter to be referred as: MAC) layer is carried out, and perhaps two-layerly cooperates execution by this.

The technical scheme of various embodiments of the present invention has solved the problem of carrying out the DRX configuration under the various CA technology of prior art proposition effectively.

1, disposes the technical scheme of identical DRX parameter than each CC of prior art, the technical scheme that the embodiment of the invention provides need not limit each CC and have identical DRX behavior, be that each CC need not be in state of activation simultaneously or be in sleep state simultaneously, each CC can control whether be in state of activation independently according to the transfer of data needs, thereby can avoid waste of electric energy;

2, than the DRX behavior difference of each CC of prior art; and dispose the technical scheme of different DRX parameters; be subject to the realization of UE; UE can use same rf chain structure to realize a plurality of CC usually; though so be the DRX parameter difference of each CC configuration; but because with enjoying rf chain, so a plurality of CC can open or close simultaneously simultaneously.As shown in Figure 6, the DRX behavior of CC1 and CC2 is different, but because CC1 and CC2 share rf chain, so in fact UE adopts different DRX parameters to monitor the CC1﹠amp that is equivalent to the third line; The waveform of CC2, listening period does not shorten, thereby can not reduce power consumption.The technical scheme of present embodiment can be distributed identical DRX parameter for the CC that shares same rf chain, and each interior CC of carrier wave set has identical DRX behavior, and electric energy therefore can avoid waste.

3, than the DRX behavior difference of each CC of prior art, and dispose the technical scheme of different DRX parameters, when a plurality of CC have independently DRX behavior, the intersection mapping relations that may have PDCCH, in physical layer such situation might appear namely, the PDCCH of a CC is placed on another CC and goes up indication, and for example the PDCCH of CC1 and CC2 is placed on the CC1, and does not carry the PDCCH of oneself on the CC2.CC2 must follow the paces of CC1, and CC2 must be in state of activation when CC1 was in state of activation, and CC1 is in state of activation else if, and CC2 is in sleep state, at this moment occurs the PDCCH of CC2 on the CC1, and CC2 has little time to activate at once and receives data.So, if CC1 and the different DRX parameter of CC2 configuration then can occur the listening period of CC1 and CC2 actual needs is superposeed to monitor, thereby can not reduce power consumption.The technical scheme of present embodiment makes that by for the CC that uses same CC carrying PDCCH distributes identical DRX parameter each CC in the carrier wave set has identical DRX behavior, and electric energy therefore can avoid waste.

On the basis of the various embodiments described above, CC is carried out the division of carrier wave set, be not limited to be the identical DRX parameter of each carrier wave set configuration, can also after according to the configuration reference information each CC being divided at least one carrier wave set, be identical Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (the Cell Radio Network Temporary Identifier of each CC distribution of same carrier wave set; Hereinafter to be referred as: C-RNTI), Timing Advance (Time Advance; Hereinafter to be referred as: TA) and/or physical-layer cell identifier (Physical CellIdentifier; Hereinafter to be referred as: PCI).

C-RNTI is for the sequence of signaling bag and packet being carried out scrambling and descrambling, the embodiment of the invention is adopted as the technological means that all CC in the same carrier wave set distribute same C-RNTI, make UE when descrambling, each CC in the same carrier wave set can use the signaling bag of the control channel of identical C-RNTI and data channel transmission and packet to carry out descrambling, can simplify the complexity that UE detects, improve detection efficiency.

TA is the transmitting time in advance of each CC of UE required setting when sending upward signal.Since different UE may with eNodeB between have different distances, different CC may have different transmission characteristics, the used time may be different on wireless propagation path to cause signal.So may there be the problem that can't arrive eNodeB at synchronization in the wireless sub-frame of upward signal, therefore TA need be set.Each upward signal that eNodeB sends UE earlier carries out time of reception to be surveyed, and determines the time of delay of each upward signal according to result of detection, thereby indicates UE how long should shift to an earlier date when this CC sends upward signal.Each CC that the embodiment of the invention is provided as same carrier wave set arranges the technological means of identical TA, if CC does not use via node to transmit in the carrier wave set, then can distribute identical TA, upward signal sends can only adopt a TA value, and then UE can only need to preserve a TA value.

And, before each CC that is same carrier wave set distributes identical TA, can also carry out the upward signal time of reception at least one CC in the carrier wave set and survey, determine the TA that all CC share in this carrier wave set according to result of detection.Then eNodeB need not repeatedly carry out the TA that operation that time of reception surveys can be determined all CC in the carrier wave set, has reduced live load.

PCI is the sign of UE employed decoding sequence when obtaining the residential quarter physical resource.Each CC in a carrier wave set can use identical PCI, then eNodeB need not be respectively the different PCI of each CC configuration, when aggregation information list informations such as each PCI and frequency points corresponding are sent to all UE by eating dishes without rice or wine, also can reduce traffic volume, reduce empty overhead.

On the basis of various embodiments of the present invention, can also be after according to the configuration reference information at least two CC being divided at least one carrier wave set, be that at least one interior CC of a carrier wave set divides the control channel that is used in control channel, as independent use carrier wave.

Each CC can be divided into two kinds, uses carrier wave and expansion carrier wave (Extension Carrier) separately.The so-called carrier wave that uses separately namely can control channel and the CC of data, can use separately.So-called expansion carrier wave namely is merely able to transmit data, and passes through the CC of other CC control channels, and therefore expanding carrier wave is non-independent use carrier wave.

The CC of same carrier wave set needs to open simultaneously, and at least one CC that therefore is adopted as in the carrier wave set divides the control channel that is used in control channel as the technical scheme of using carrier wave separately, can reach the effect of saves energy.Because if all CC in the same carrier wave set are the expansion carrier wave, when then the CC of this carrier wave set opens, also need the independent use carrier wave in another carrier wave set also to open, namely all CC of another carrier wave set also need to open, and have significantly increased power consumption.

The technical scheme of various embodiments of the present invention is not limited in the LTE network, can be widely used in having multicarrier, carry out the DRX configuration in the sending/receiving system under a plurality of simultaneous resource situation.

Embodiment five

The flow chart of the implementation method of the another kind of discontinuous reception configuration that Fig. 7 provides for the embodiment of the invention five, present embodiment can be carried out by UE, comprises the steps:

Step 701, UE obtain each the self-corresponding configuration reference information of at least two CC of self;

Step 702, UE will dispose reference information and report network side configuration network element, or will report network side configuration network element according to the carrier wave set information that the configuration reference information is divided at least one carrier wave set with at least two CC;

Step 703, UE identify from DRX parameter and the CC each carrier wave set that network side configuration network element is received as each carrier wave set configuration.

In the present embodiment, UE can directly report the configuration reference information of each CC such network side configuration network element such as eNodeB, also can carry out the division of carrier wave set according to the configuration reference information voluntarily for UE, carrier wave set information after then will dividing reports network side configuration network element, for each carrier wave set configuration DRX parameter, be handed down to UE by network side configuration network element again.

The configuration reference information is the foundation of configuration DRX parameter as described in the aforementioned embodiment, also as the foundation of dividing carrier wave set, and can be for the mapping relations of the PDCCH of the rf chain information of CC correspondence and/or each CC etc.

When the configuration reference information comprises the corresponding rf chain information of each CC, will at least two CC be divided at least one carrier wave set according to the configuration reference information and be divided into a carrier wave set for the CC that will have the same radio frequency chain information.

When the configuration reference information comprised the mapping relations of PDCCH of each CC, will at least two CC being divided at least one carrier wave set according to the configuration reference information can be divided into a carrier wave set for the CC that will adopt same CC to carry PDCCH.

Preferably in conjunction with the mapping relations of rf chain information and PDCCH, will have the same radio frequency chain information or adopt the CC of same CC carrying PDCCH to be divided into a carrier wave set.

Reporting of carrier wave set information can be reporting of independent message in the present embodiment, also can be to be carried in the ability information to report.Carrier wave set information can be the sign of carrier wave set, and for example, a carrier wave set sign is corresponding with the sign of one or more CC, represents namely which CC is this carrier wave set comprise.
