The wireless communication system of evolution can provide higher transmission rate, shorter propagation delay time, and the mobility between 3G (Third Generation) Moblie partnership project (The 3rd Generation Partnership Project, referred to as 3GPP) inter Access System and between 3GPP connecting system and non-3 GPP access system can be supported.
Fig. 1 is Long Term Evolution (Long Term Evolution, referred to as LTE) system/System Architecture Evolution (System Architecture Evolution, referred to as SAE) next generation network configuration diagram, as shown in Figure 1, it comprises Radio Access Network (the Evolved Radio Access Network of evolution, referred to as E-RAN) and the packet core network (Evolved Packet Core Network, referred to as E-PCN) of evolution.Wherein, E-RAN is made up of the base station (eNodeB, referred to as eNB) of evolution, and E-PCN is by Mobility Management Entity (Mobility Management Entity, referred to as MME) and service gateway entity (Serving Gateway, referred to as S-GW) composition.Interface between eNB and core network is S1 interface, and wherein, the interface between eNB and MME is expressed as S1-MME, for completing the chain of command function of mobile management and S1 interface; Interface between eNB and S-GW is expressed as S1-U, for the function such as route, transmission of completing user data.Be connected by X2 interface between eNB, X2 interface is used for the information interaction between the eNB of completing user equipment (User Equipment, referred to as UE) mobile management function in active state and equity.
When subscriber equipment is in connection status in LTE system, network distributes Radio Network Temporary Identifier (Radio Network Temporary Identifier for it, referred to as RNTI), subscriber equipment needs in descending sub frame, detect all Physical Downlink Control Channel (Physical downlink controlchannel, referred to as PDCCH), the PDCCH belonging to this subscriber equipment and the Physical Downlink Shared Channel being positioned at same subframe (Physical downlink shared channel, referred to as PDSCH) is detected according to RNTI.In LTE, radio frames (radio frame) be 10 milliseconds as shown in Figure 2, be made up of 10 subframes (sub-frame), each subframe 1 millisecond, subframe is made up of to subframe 9 subframe 0 in a radio frame, and each subframe is made up of two time slots (slot).The all corresponding System Frame Number (System Frame Number, referred to as SFN) of each radio frames, System Frame Number recycles from 0 to 1023.
Comprise in existing radio resource control RRC (Radio Resource Control) signaling and discontinuous reception (Discontinuous Reception is set, referred to as DRX) information, network settings DRX is the power saving etc. of demand from the viewpoint of business and subscriber equipment.When the subscriber equipment being in connected state does not configure DRX, subscriber equipment needs continuous print to detect PDCCH, detects one's own PDCCH; When being in the user device configuration DRX of connected state, subscriber equipment only needs to detect PDCCH (being in awake state) at activationary time (Active-time) continuous print, and all the other times do not need to detect PDCCH (being in sleep state).Although the use of DRX can reduce the detection of subscriber equipment to PDCCH, but subscriber equipment still needs continuous print to detect PDCCH at Active-time.
In order to meet the demand of people to more high bandwidth, LTE Advance proposes to adopt carrier aggregation (carrier aggregation, be called for short CA) method realize the object of more large bandwidth, now by multiple continuous or discrete carrier wave, (each carrier wave is called component carrier in a community, Component Carrier) composition, can simultaneously for UE provides the service of multicarrier.Component carrier can adopt the carrier wave of compatible LTE system, and this carrier wave is called backward compatibility carrier wave; Component carrier also can adopt the carrier wave of incompatible existing LTE system, and this carrier wave is called non-backward compatible carrier waves, and this carrier wave can only be that Release 10 version and above UE use.

Be described in detail below in conjunction with the specific implementation of example to the embodiment of the present invention.
Example one:
In LTE system, UE is positioned at Serving cell and is in connection status, and UE has the operating carriers of uplink and downlink respectively.UE needs continuous print to detect PDCCH, detects one's own PDCCH according to the RNTI of oneself.In order to realize the present invention, network side is by the schedule information of space interface signaling notice UE subsequent time period, after UE receives this schedule information, to know when network will dispatch oneself in advance, UE just can at suitable time detecting PDCCH, avoids continuous print to detect PDCCH and the invalid computing that causes and energy loss.
Network side is by wireless heterogeneous networks (Radio Resource Control, referred to as RRC) signaling, medium access control layer signaling or physical downlink control channel (Physical Downlink ControlChannel, referred to as PDCCH) etc. space interface signaling schedule information is notified UE, that is: the schedule information of network side notice UE subsequent time period.
Described subsequent time period can be limited temporal information such as 10 milliseconds, also can be the temporal information of endless, and namely network dispatches this UE with certain ad hoc fashion (as periodically) always; Subsequent time period can be after UE receives described space interface signaling back to back a period of time as back to back 10 milliseconds, also can be receive described signaling after non-back to back a period of time, now the mode of acquiescence can be pointed out or adopt to the initial time of this period of time in the signaling, the mode of acquiescence such as from next radio frames (radio frames 10 milliseconds) original position or N number of radio frames original position start.The exact time that network side also can be indicated the initial of subsequent time period by space interface signaling and/or be stopped, namely illustrates the length of subsequent time period by indicating the termination time (or subframe).
Described schedule information can be time or the sub-frame information (namely there is time or the sub-frame information of the PDCCH of this UE) that network side dispatches this UE, also can be time or the sub-frame information of not dispatching this UE.
Medium access control layer signaling is also known as MAC balancing boom (MAC Control Elements, referred to as MAC CE), existing MAC CE comprises buffer status report (Buffer StatusReport), the power headroom (Power Headroom) that UE reports, and also comprises CRNTI, TA order (Timing Advance Command) etc. of network configuration.If network side is by the schedule information of medium access control layer (MAC) signaling UE subsequent time period, in order to realize the schedule information of network side notice UE subsequent time period, need to expand existing MAC CE, make it comprise the schedule information of UE at subsequent time period.
Schedule information can be time or the sub-frame information of this UE of scheduling in back to back 10 milliseconds (subsequent time period) after UE receives this medium access control layer signaling, such as can dispatch this UE back to back 1st millisecond, the 5th millisecond and the 8th millisecond.After UE receives this medium access control layer signaling, only need to detect PDCCH, also without the need to detecting continuously in whole subsequent time period back to back 1st millisecond, the 5th millisecond and the 8th millisecond.All the other times in these back to back 10 milliseconds (subsequent time period), UE can close rf receiver unit to save energy, and these free time also can be utilized to go to obtain the system message (if needing to obtain the system message of adjacent area) of adjacent area or do other thing.
It should be noted that, network side can transmit new schedule information at back to back 5th millisecond or the 8th millisecond, performs the detection of PDCCH after UE receives new schedule information according to new schedule information.

Network side is by wireless heterogeneous networks (Radio Resource Control, referred to as RRC) signaling, medium access control layer signaling or physical downlink control channel (Physical Downlink ControlChannel, referred to as PDCCH) etc. space interface signaling by the schedule information of subsequent time period notice UE, that is, network side notice UE is in the schedule information of these two carrier wave subsequent time period.
Described subsequent time period, can be limited temporal information such as 20 milliseconds, also can be the temporal information of endless, and namely network dispatches this UE with certain ad hoc fashion (as periodically) always; Subsequent time period can be after UE receives described space interface signaling back to back a period of time as back to back 20 milliseconds; Also can be receive described space interface signaling after non-back to back a period of time, now the mode of acquiescence can be pointed out or adopt to the initial time of this period of time in the signaling, the mode of acquiescence such as from next radio frames (radio frames 10 milliseconds) original position or N number of radio frames original position start.
Described schedule information, can be time or the sub-frame information (namely there is time or the sub-frame information of the PDCCH of this UE) that network side dispatches this UE, also can be time or the sub-frame information of not dispatching this UE.Network side can notify the schedule information of UE at these two carrier wave CC (f1) and CC (f2) subsequent time period by descending CC (f1), also can on descending CC (f1) and descending CC (f2), indicate UE in the schedule information of respective carrier wave subsequent time period respectively respectively.If in the schedule information of some descending carrier instruction UE at other carrier wave subsequent time period, network side needs to indicate carrier information in space interface signaling, and carrier information or can represent by carrier index (Carrier Index) or represent by the physical layer identifications of carrier wave or mark of overall importance with frequency representation.
Sometime, UE receives by RRC signaling or MAC signaling or PDCCH the signaling that network side sends at descending CC (f1), comprise this UE in the signaling respectively in the schedule information of descending CC (f1) and descending CC (f2) subsequent time period, in the present embodiment, the original position of subsequent time period adopts default setting, for starting after 10 milliseconds after receiving this signaling, the length of subsequent time period can by signal deployment or default setting, and the length of subsequent time period adopts default setting to be 20 milliseconds in the present embodiment.Schedule information is in 20 milliseconds after receiving signaling after 10 milliseconds, and some specific subframe can dispatch this UE.
UE receives this with after the space interface signaling of schedule information, needs the PDCCH detected continuously in follow-up 10 milliseconds on two carrier waves, only needs the PDCCH detected in specific subframe on respective carrier wave in 20 milliseconds after these 10 milliseconds.In all the other times, UE can close rf receiver unit to save energy, and these free time also can be utilized to go to obtain the system message (if needing to obtain the system message of adjacent area) of adjacent area or do other thing.After future time length, UE needs to detect PDCCH continuously.
It should be noted that, be described for continuous print component carrier in this example, roughly the same with the process of continuous print component carrier to the process of discontinuous component carrier, do not repeat them here.
Example three:
This exemplary application scene is LTE Advance system, and UE is in idle condition in carrier aggregation subdistrict.The component carrier that the community of this carrier aggregation comprises is in frequency band 1 (Band 1), descending have 3 continuous print component carrier CC (f1), CC (f2), CC (f3), up is also 3 continuous print carrier wave CC (f4), CC (f5), CC (f6), it should be noted that, identify this component carrier with the frequency information of each component carrier in this example, but the present invention does not limit to carrier identification mode.Three the equal transmitting system message of descending carrier, beep-page messages.
Sometime, UE is at up CC (f4), and descending CC (f1) initiates Stochastic accessing, successfully accesses the community of this carrier aggregation.Because UE supports multicarrier and service traffics are very large, base station is again for UE is assigned with component carrier UL CC (f5) and UL CC (f6), DL CC (f2) and DL CC (f3), that is, now the up-link carrier collection of UE and the descending carrier collection of UE all comprise three carrier waves.In the present embodiment, network side is by the schedule information of physical downlink control channel PDCCH instruction subsequent time period, and subsequent time period can comprise that subframe receiving PDCCH signaling.
Sometime, network side indicates the schedule information of UE subsequent time period in the PDCCH of DL CC (f1), assuming that it is be 3 at SFN that UE receives this PDCCH, subframe is the moment of 4, UE is in the schedule information of this descending carrier back to back 10 subframes (namely 10 milliseconds) in network side instruction, network side also indicates UE to be 3 at SFN simultaneously, subframe is the number of the moment scheduling UE of 4, namely now network side sends the PDCCH of this UE at several descending carrier, or dispatch the PDCCH number of this UE, network side can also indicate the clear and definite carrier information of this UE of scheduling (by frequency, or carrier index represents, or represent by the physical layer identifications of carrier wave or mark of overall importance, such UE just can only need to detect specific carrier wave, network side can indicate the carrier information not dispatching this UE as an alternative), network side also indicates the number of UE each subframe scheduling UE in back to back 10 subframes (can be dispatch the Physical Downlink Control Channel number of this subscriber equipment in each subframe or dispatch the variable number of this subscriber equipment), and network can also indicate the carrier information of each this UE of subframe scheduling (represent by frequency or carrier index or represent by the physical layer identifications of carrier wave or mark of overall importance).
Network side instruction UE is in the number (or PDCCH number of this UE) of each this UE of subframe scheduling, the detection of UE to multicarrier can be reduced, such as UE in each subframe according to DL CC (f1), CC (f2), CC (f3) detects PDCCH successively, if UE knows the number of network side scheduling oneself in this subframe, just can stop detecting after the PDCCH meeting number being detected, if special UE is after the PDCCH detecting DL CC (f1), one's own PDCCH is detected according to RNTI, know that again present sub-frame scheduling number is 1, UE just can detect the PDCCH of DL CC (f2) and DLCC (f3) again.Equally, if network side instruction UE is at the carrier information of each this UE of subframe scheduling, UE can detect specific carrier wave according to clear and definite carrier information, avoid unnecessary detection.
It should be noted that, network side can only instruction receive the number (variable number dispatching this UE or the PDCCH number of dispatching this UE) of this UE of scheduling of the present sub-frame of PDCCH or dispatch the carrier information of this UE, also can indicate the present sub-frame comprising and receive PDCCH and later each this UE of subframe scheduling of a period of time number or dispatch the carrier information of this UE, a period of time (and then or and then non-) can also be indicated after receiving this PDCCH to dispatch the number of this UE or dispatch the carrier information of this UE.Network side can only indicate this UE in the information of the definite subframe of current carrier scheduling (or not scheduling) this UE, and this UE also can be indicated in the information of the definite subframe of other one or more carrier dispatchings (or not scheduling) this UE.Said method also can combinationally use by network side.
