Above-mentioned its length maybe for 0bit (promptly; Do not have this bit position) be in existing R8/R9/R10 operating such; LTE system for the R11 version; If the RRC signaling be UE some DRX parameter configuration two the cover values, then in DCI information, exist corresponding bit position to be used to indicate current use where to overlap parameter.Where definite use overlaps the value that can use corresponding bit of parameter is directly confirmed, as: if corresponding bit is made as 0, then use the acquiescence value; If corresponding bit is made as 1, then use the expansion value.
Be example with DRX parameter d rx-InactivityTimer still, after expansion RRC signaling, this parameter has two values.Wherein, the original value that has just existed is used as the acquiescence value, at the beginning of system configuration DRX parameter, UE uses and should give tacit consent to value; When UE receives that the respective flag position DRX inactivity timer modification indicator of PDCCH is set to 1, then change it into newly-increased value.If receive that again the respective flag position DRX inactivity timer moddification indicator of PDCCH is set to 0, then changes it into acquiescence value again afterwards.
Instance 3: expansion RRC signaling is the optional value of part DRX parameter configuration two covers of UE, defines the relevant MAC CE of new DRX simultaneously, and the DRX Command MAC CE through redetermination indicates which cover configuration parameter of the current use of UE.Concrete:
Layoutprocedure: expansion RRC signaling is the optional value of part DRX parameter configuration two covers of UE.
This embodiment is consistent with embodiment 1 for the expansion of RRC signaling, and this place provides the situation of while spreading parameter drx-InactivityTimer and onDurationTimer.The method that it may be noted that present embodiment stands good in the situation of spreading parameter drx-InactivityTimer or onDurationTimer only, even expands the situation of other DRX parameter.
Notification procedure: define the relevant MAC CE of new DRX, carry out parameters of choice.
Which DRX parameter new DRX Command MAC CE and the corresponding LCID of definition is used to indicate need change in the MAC agreement.Definition Extended DRX Command MAC CE such as Fig. 8 A, which DRX parameter this MAC CE is used to indicate to be revised as another set of value.
Among the Extended DRX Command MAC CE, the implication of each parameter is as shown in table 1.
In order to identify the DRX Command MAC CE of this redetermination, need to introduce new LCID, utilize the reservation index (as: index 11010) among original LCID, with the transmission of this index sign Extended DRX Command MAC CE, as shown in table 2.
MAC the form that carries Extended DRX Command MAC CE is shown in Fig. 8 B.
In the MAC agreement, introduce new DRX Command MAC CE and corresponding LCID, be used to indicate which DRX parameter can change and changing mode.Be DRX parameter d rx-InactivityTimer and each self-configuring two cover RRC parameter value of onDurationTimer; For above-mentioned two parameters; With the original DRX parameter value that had just existed among this IE (value of drx-Config field indication among the IE MAC-MainConfig) as acquiescence value (value 1), with increasing the value that comprises among the parameter d rx-Config-r11 newly as alternative value (value 2).
With indication drx-inactivitytimer parameter modification among the new DRX Command MAC CE is example, and being located in the RRC configuration allocating default value and being psf1, to dispose alternative value be psf3.When rare of small data, drx-inactivitytimer uses this acquiescence value configuration of psf1; In case the eNB load is heavy slightly, send Extended DRX Command MAC CE, inform that UE brings into use the alternative value psf3 of drx-inactivitytimer parameter; In case the eNB load lightens once more, can send Extended DRX Command MAC CE once more, informs that UE brings into use the acquiescence value psf1 of drx-inactivitytimer parameter.
Instance 4: expansion RRC signaling; The optional value of part DRX parameter configuration two covers for UE; In the RRC signaling, increase the time span of its effect of spreading parameter simultaneously; Expand existing MAC CE then or introduce new MAC CE or expand DCI information, indicate whether to change corresponding DRX values of parameters into the expansion value.Concrete:
Layoutprocedure: expansion RRC signaling.
Still the value with spreading parameter drx-inactivitytimer is an example; The scheme that present embodiment is described need be beyond the value of embodiment 1 spreading parameter drx-inactivitytimer; Also need in the RRC signaling, increase the times N that comes into force of expanded configuration; Detailed directions is the value of operation acquiescence earlier; After the DCI information of the existing DRX Command MAC CE that receives expansion or new DRX Command MAC CE or expansion; When this drx-inactivitytimer of operation; N time (N time can be continuous by expanded configuration value operation drx-inactivitytimer; Also can be discontinuous) after, when moving drx-inactivitytimer once more, reuse this timer of acquiescence value configuration operation (the bit number of this duration of present embodiment hypothesis indication is
bit) of drx-inactivitytimer:
Notification procedure: newly-increased or expansion L2/L1 signaling.
Can expand the DCI information of existing DRX Command MAC CE, newly-increased Extended DRX Command MAC CE or expanded downstream scheduling according to the method for describing in instance 1～instance 3, realize choosing of parameter.
Method with the existing DRX Command MAC CE of expansion in the instance 1 is an example; The concrete grammar of present embodiment is described: after network side has disposed DRX parameter (comprising original RRC parameter and expansion RRC parameter); Receive that R bit is set to before 1 the DRX Command MAC CE, UE confirms the concrete value of drx-inactivitytimer parameter according to the parameter configuration among the drx-Config that carries among the IEMAC-MainConfig.If receive that R bit is set to 1 DRX Command MAC CE, then immediately drx-inactivitytimer is changed into the value of expansion, and the access times of the expansion value that adds up.After the drx-inactivitytimer of UE uses the expansion value to surpass the effective degree upper limit drx-extendedParameterCycle-r11 of RRC setting; UE changes drx-inactivitytimer into concrete value that parameter configuration among the drx-Config that carries among the IEMAC-MainConfig is confirmed the drx-inactivitytimer parameter again, and the modification of this moment does not need the signaling of network side.
Instance 5: do not expand the RRC signaling, the relevant MAC CE of newly-increased DRX reconfigures the DRX parameter that can change flexibly.Concrete:
Layoutprocedure: in the scheme of present embodiment, the RRC signaling is merely the DRX parameter configuration 1 cover value of UE, and this is consistent with existing R8/R9/R10 agreement.
Notification procedure: which DRX parameter new DRX Command MAC CE and the corresponding LCID of definition in the MAC agreement is used to indicate need change.The DRX parameter that can change flexibly can be one or more among drx-InactivityTimer, the onDurationTimer etc.Still need change value with DRX parameter d rx-inactivitytimer is example; Definition Extended DRX Inactivity Timer MAC CE is as shown in Figure 9, and this DRX Command MAC CE is used to indicate the DRX parameter to need drx-inactivitytimer need be revised as which value.
Among the Extended DRX Inactivity Timer MAC CE, the implication of each parameter is as shown in table 3.The corresponding relation of DRX parameter value and bit information as shown in table 4.
In order to identify the DRX Command MAC CE of this redetermination; Need to introduce new LCID; Utilize the reservation index (as: index 11010) among original LCID, with the transmission of this index sign Extended DRX Inactivity Timer MAC CE, as shown in the table:
MAC the form that carries Extended DRX Inactivity Timer MAC CE is shown in Fig. 8 B.
In the MAC agreement, introduce new DRX Command MAC CE and corresponding LCID, be used to indicate which DRX parameter can change and changing mode.The value of drx-inactivitytimer is set is psf1 to the drx-Config field in supposing in RRC configuration through EMAC-MainConfig, and when rare of small data, drx-inactivitytimer uses this RRC signaling value configuration of psf1; In case eNB load is heavy slightly, sends new Extended DRX Inactivity Timer MAC CE, the bit of T4～T0 is set to " 00010 " simultaneously, informs that UE drx-inactivitytimer parameter brings into use the configuration of psf3; In case the eNB load changes once more; Can send Extended DRX Inactivity Timer MAC CE once more; The drx-inactivitytimer parameter of informing UE is brought into use other value configuration; As: the bit of T4～T0 of Extended DRX Inactivity Timer MAC CE is set to " 00110 ", and this moment, the drx-inactivitytimer parameter of UE was brought into use value psf8.
