First the DRX control flow of base station side is introduced.
As shown in Figure 1, be the non-continuous receiving control method flow chart of the base station side that the embodiment of the present invention one proposes, its concrete handling process is as follows, comprising:
Step 11, the carrier wave needing to carry out DRX control, in each carrier wave that UE is corresponding, is determined in base station.
Step 12, sends to described UE by the carrier identification of the carrier wave determined, the carrier wave indicating described UE corresponding to the carrier identification received carries out DRX control.
In the embodiment of the present invention one, DRX being carried out to carrier wave and controls to enter sleep state for controlling carrier wave, also can be waken up by sleep state for controlling carrier wave.Introduce the DRX control program under both of these case below respectively.
Situation 1, control carrier wave are by entering sleep state.
When UE control carrier wave enters sleep state, the receiver of this carrier wave can be closed, namely the receiver of the radio frequency link at this carrier wave place is closed, radio frequency link can support several carrier waves, if therefore UE closes the receiver of certain radio frequency link, then all carrier waves on this radio frequency link all enter sleep state.
The embodiment of the present invention one proposes, base station is before carrying out DRX control to the carrier wave of UE, first can determine whether UE can support at least two radio frequency links, if UE can support at least two radio frequency links, the carrier wave that the scheme control UE that then can propose according to the embodiment of the present invention is corresponding enters sleep state, if UE can only support a radio frequency link, then can conventionally in carrier wave corresponding to scheme control UE enter sleep state.
It should be noted that, above-mentioned steps is optional step, even if UE can only support a radio frequency link, the carrier wave that the scheme control UE that also can propose according to the embodiment of the present invention is corresponding enters sleep state.
Determine to enable base station whether UE supports at least two radio frequency links, the embodiment of the present invention one proposes, UE can to base station reporting radio frequency link tenability information, and base station, according to the radio frequency link tenability information received, determines whether UE can support at least two radio frequency links.
Wherein, radio frequency link tenability information can be carried in UE ability information (Capability Information) and report base station by UE.In Capability Information, radio frequency link tenability information 1 bit or multiple bit represents.If represent with 1 bit, then 1 express support for two radio frequency links, two radio frequency links are not supported in 0 expression; If represent with 2 bit, then 10 express support for 2 radio frequency links, 11 express support for 3 radio frequency links.
The base station carrier wave corresponding to UE carries out DRX when controlling, first in each carrier wave that UE is corresponding, select and need to enter dormant carrier wave, concrete, base station is in each carrier wave that UE is corresponding, determine the carrier wave no longer dispatched in setting-up time section, then the carrier wave determined is entered dormant carrier wave as needs.
The embodiment of the present invention one proposes, base station is after selecting and needing to enter dormant carrier wave, directly the carrier wave selected can be confirmed as the carrier wave needing to carry out DRX control, and carrier identification is sent to UE, the carrier wave that instruction UE is corresponding to the carrier identification received carries out DRX control.
In addition, when UE control carrier wave enters sleep state, can close the receiver of this carrier wave, namely close the receiver of the radio frequency link at this carrier wave place, if the radio frequency link at this carrier wave place also comprises other carrier waves, then other carrier waves also correspondingly can enter sleep state.Therefore, in order to not affect the Business Processing of the carrier wave of normal work, the embodiment of the present invention one proposes, base station is after selecting and needing to enter dormant carrier wave, can also according to the radio frequency link at carrier wave place, the carrier wave selected further is screened, using the carrier wave filtered out as needing the carrier wave carrying out DRX control.Concrete screening process is as follows:
The radio frequency link information of UE can report this UE corresponding each carrier wave to base station.The radio frequency link information of each carrier wave that UE is corresponding can be carried in UE Capability Information and report base station, also can set up RRC at UE and connects or dynamically report when carrying out carrier aggregation associative operation.Described radio frequency link information can be the correspondence relationship information between radio frequency link and carrier wave, as shown in table 1:
Table 1:
Described radio frequency link information can be also be positioned at the information on similar and different radio frequency link for those carrier waves, such as, UE reports following information to base station: the carrier wave A of self correspondence and carrier wave B is positioned on same radio frequency link, and carrier wave C is positioned on another one radio frequency link.
Base station is after selecting and needing to enter dormant carrier wave, the radio frequency link information of that report according to UE, that this UE is corresponding each carrier wave, the carrier wave be positioned on same radio frequency link is determined in the carrier wave selected, whether the radio frequency link being positioned at the carrier wave place on same radio frequency link that then judgement is determined also exist other carrier waves, if judged result is no, then the carrier wave on this radio frequency link is confirmed as the carrier wave needing to carry out DRX control.
Such as, the carrier wave that UE is corresponding comprises carrier wave A, carrier wave B, carrier wave C, carrier wave D and carrier wave E, wherein, carrier wave A, carrier wave B and carrier wave C to be positioned on radio frequency link 1, carrier wave D and carrier wave E is positioned on radio frequency link 2, base station selected go out need that to enter dormant carrier wave be carrier wave A, carrier wave B, carrier wave C and carrier wave E, carrier wave A is determined in base station, carrier wave B, carrier wave C is positioned on identical radio frequency link 1, and there are not other carrier waves in radio frequency link 1, therefore by carrier wave A, carrier wave B, carrier wave C confirms as the carrier wave needing to carry out DRX control, and the radio frequency link 2 at carrier wave E place also exists carrier wave D, therefore carrier wave D is not confirmed as the carrier wave needing to carry out DRX control by base station.

Embodiment two
Introduce the DRX control flow of UE side below.
As shown in Figure 4, be the non-continuous receiving control method flow chart that the embodiment of the present invention two proposes, its concrete handling process is as follows, comprising:
Step 41, UE receives carrier identification that base station sends, that need the carrier wave carrying out DRX control.
Step 42, the carrier wave that described UE is corresponding to the carrier identification received carries out DRX control.
In the embodiment of the present invention two, DRX being carried out to carrier wave and controls to enter sleep state for controlling carrier wave, also can be waken up by sleep state for controlling carrier wave.Introduce the DRX control program under both of these case below respectively.
Situation 1, control carrier wave are by entering sleep state.
The method that base station describes according to situation 1 in the embodiment of the present invention one carries out DRX control, select in each carrier wave that UE is corresponding and need to enter dormant carrier wave, using the carrier wave selected as needing the carrier wave carrying out DRX control, and carrier identification is sent to UE.That is, above-mentioned need the carrier wave carrying out DRX control be that base station is selected in each carrier wave that UE is corresponding, need to enter dormant carrier wave.
If base station sends to UE by needing the carrier identification of the carrier wave carrying out DRX control to be carried in MAC PDU, then the process of the carrier identification of UE reception base station transmission is as follows:
UE receives the MAC PDU that base station sends, and then from the MAC PDU received, extract the carrier identification needing the carrier wave carrying out DRX control, the structure of MAC PDU as shown in Figure 2.
Concrete, UE extracts and is used to indicate carrier wave and enters a dormant LCID from the MAC head of MAC PDU, if there is a LCID in MAC head, then UE just thinks that needing to control carrier wave enters sleep state, therefore the position that UE is corresponding with a LCID in MAC control element, extracts the carrier identification needing to enter dormant carrier wave.
Such as, one LCID is 01111, if occur 01111 in MAC head, then UE thinks that needing to control carrier wave enters sleep state, and therefore UE position corresponding with 01111 in MAC control element extracts the carrier identification needing to enter dormant carrier wave.
When carrier identification is carried in base station in MAC control element, the form of bitmap can be adopted to carry, when so UE extracts carrier identification in MAC control element, the carrier wave that can be 1 mark position is confirmed as and is needed to enter dormant carrier wave.
In situation 1, when the carrier wave that UE is corresponding to the carrier identification extracted carries out DRX control, suspend the DRX timer that carrier wave is current, close the receiver of carrier wave, namely close the receiver of the radio frequency link at carrier wave place, make carrier wave enter sleep state.After carrier wave enters sleep state, no longer monitor PDCCH channel.
In addition, the embodiment of the present invention two proposes, and UE can also report self radio frequency link tenability information in advance to base station, to make base station according to the radio frequency link tenability information of UE, determine whether UE can support at least two radio frequency links.Wherein, radio frequency link tenability information can be carried in UE Capability Information and report base station by UE.
Further, UE can also report the radio frequency link information of each carrier wave of self correspondence to base station, enters dormant carrier wave screen to enable base station according to the radio frequency link information that UE reports to needs.The radio frequency link information of each carrier wave can be carried in UE Capability Information and report base station by UE, also can connect setting up RRC or dynamically report base station when carrying out carrier aggregation associative operation.
Situation 2, control carrier wave are waken up by sleep state.
The method that base station describes according to situation 2 in the embodiment of the present invention one carries out DRX control, the carrier wave needing to be waken up by sleep state is selected in each carrier wave that UE is corresponding, using the carrier wave selected as needing the carrier wave carrying out DRX control, and carrier identification is sent to UE.That is, above-mentioned need the carrier wave carrying out DRX control be that base station is selected in each carrier wave that UE is corresponding, need the carrier wave that is waken up by sleep state.
If base station sends to UE by needing the carrier identification of the carrier wave carrying out DRX control to be carried in MAC PDU, then the process of the carrier identification of UE reception base station transmission is as follows:
UE receives the MAC PDU that base station sends, and then from the MAC PDU received, extract the carrier identification needing the carrier wave carrying out DRX control, the structure of MAC PDU as shown in Figure 2.
Concrete, UE extracts the 2nd LCID being used to indicate carrier wave and being waken up by sleep state from the MAC head of MAC PDU, if there is the 2nd LCID in MAC head, then UE just thinks needs to wake dormant carrier wave up, therefore the position that UE is corresponding with the 2nd LCID in MAC control element, extracts the carrier identification needing the carrier wave be waken up by sleep state.
Such as, 2nd LCID is 10001, if occur 10001 in MAC head, then UE thinks needs to wake dormant carrier wave up, and therefore UE position corresponding with 10001 in MAC control element extracts the carrier identification needing the carrier wave be waken up by sleep state.
When carrier identification is carried in base station in MAC control element, the form of bitmap can be adopted to carry, when so UE extracts carrier identification in MAC control element, the carrier wave that can be 1 mark position is confirmed as needs the carrier wave that is waken up by sleep state, flag bit be 0 carrier wave keep sleep state.
In situation 2, when the carrier wave that UE is corresponding to the carrier identification extracted carries out DRX control, the receiver of carrier wave can be opened immediately, control carrier sense PDCCH, carrier wave is waken up by sleep state immediately; Also when the initial time of next DRX cycle arrives, the receiver of carrier wave can be opened, controls carrier sense PDCCH, carrier wave is waken up by sleep state.
The embodiment of the present invention two proposes, UE determines the carrier wave needing to carry out DRX control according to the carrier identification that base station sends after, if need each carrier wave carrying out DRX control not on same radio frequency link, then each carrier wave can be adjusted on same radio frequency link by UE, and reports the radio frequency link information that each carrier wave after adjustment is corresponding to base station.
The step that UE adjusts the radio frequency link at carrier wave place is optional step, and whether network side can perform this step by pre-configured UE.
It should be noted that, when needing the carrier wave of control UE to enter sleep state, base station and UE can conventionally in scheme control carrier wave and carry out sleep state, the method that also can describe according to situation 1 in the embodiment of the present invention one and embodiment two controls carrier wave carry out sleep state; When needing the carrier wave of control UE to be waken up by sleep state, UE can conventionally in scheme wake carrier wave up (after the carrier wave that namely UE is corresponding enters sleep state, when the initial time of next DRX cycle arrives, UE wakes dormant carrier wave up), the method that also can describe according to situation 2 in the embodiment of the present invention one and embodiment two wakes carrier wave up.Specifically comprise following four kinds of combined situation:
