The discontinuous reception method for the multi-carrier system comprises that: the terminal acquires discontinuous reception (DRX) parameter information, configured for a multi-carrier user by a network side, over the downlink control channel; and the terminal maintains timers of corresponding carriers and executes related DRX operations according to a current cache state and/or the scheduling conditions of each carrier, wherein the time length of the timer is set according to timer information in the DRX parameter information.
Description
Technical field
The present invention relates to communication technical field, particularly a kind of multicarrier system and discontinuous receiving method thereof and device.
Background technology
Discontinuous reception (Discontinuous Reception at LCR TDD, DRX) in technology, single carrier subscriber equipment (UE) is descending while there is no data activity within a period of time, there is the UE of DRX ability can use DRX mechanism, discontinuous monitoring down control channel, can reach power saving like this, extend the object of the battery of UE.
Here DRX refers to that UE is for the discontinuous monitoring of down control channel, be E-AGCH (E-DCHAbsolute Grant Channel, E-DCH absolute grant channel, E-DCH, Enhanced DedicatedChannel, strengthens dedicated channel), HS-SCCH (Shared Control Channel for HS-DSCH, shared control channel for HS-DSCH, HS-DSCH, High Speed Downlink SharedChannel, high speed descending sharing channel).
DRX mechanism under the CELL_DCH state of single carrier UE in HSPA+ (CELL_DCH state is that Radio Resource is controlled a kind of of (RRC, Radio Resource Control) state) is as follows:
One, the DRX of the HS-SCCH of UE under CELL_DCH mechanism:
If UE has started DRX function, for descending:
If configured DRX timer parameter (Inactivity_Threshold_for_HS_SCCH_DRX_cycle), UE receives after HS-SCCH, after having fed back HS-SICH, UE starts or restarts SCCH_DRX timer, in timer time (Inactivity_Threshold_for_HS_SCCH_DRX_cycle), UE, for the reception of HS-SCCH in RX state, enters DRX state after timer expiry.The RX state here refers to continuous monitoring control channel HS-SCCH, and DRX state refers to discontinuous monitoring control channel HS-SCCH.
If do not configure DRX timer parameter (Inactivity_Threshold_for_HS_SCCH_DRX_cycle), UE receives control channel HS-SCCH according to the DRX pattern of HS-SCCH.
Two, the E-AGCH monitoring mechanism of UE under CELL_DCH:
If UE has started DRX function, for up:
E-AGCH DRX info (set of a part of information element in RRC signaling) does not have, in the situation of configuration, if UE has semi-continuous resource, will monitor continuously E-AGCH so.If configured semi-continuous resource and now configured E-AGCH DRX info, so still monitored E-AGCH according to the mode of DRX.
Shown in Figure 1, if configured E-AGCH Inactivity Monitor Threshold parameter, when UE reports TEBS (Total E-DCH Buffer Status, the total buffer status of E-DCH) be 0, UE receives after ACK (Acknowledgement confirms) feedback of E-HICH, starts AGCH_DRX timer, in timer time, UE, for the reception of E-AGCH in RX state, enters DRX state after timer expiry.If UE under E-AGCH DRX state separately at the MAC-e PDU/MAC-iPDU (protocol Data Unit of MAC-e or MAC-i entity, PDU, Protocol Data Unit, protocol Data Unit, MAC-e and MAC-i are the titles of the entity in MAC layer, do not have Chinese to explain) the middle schedule information (scheduling information, SI) that sends, and indication TEBS is 0, and timer does not start or restarts.If terminal has sent E-PUCH in DRX state, and carried TEBS > 0, terminal enters RX state immediately.When UE reports after TEBS > 0, enter immediately RX (Reception receives continuously) state, terminal can be monitored E-AGCH continuously.
If do not configure E-AGCH Inactivity Monitor Threshold parameter, according to current parameter configuration, even if the timer of E-AGCH DRX does not appear in E-AGCH DRX info, but this timer still must be joined in E-AGCH info, so still can carry out DRX operation according to the mode of timer.
If E AGCH Inactivity Monitor Threshold set timer is endless, think and only have enabling delay just can make terminal enter DRX, once but dispatch terminal or receive the TEBS > 0 of terminal to report, will be considered as terminal and exit DRX, and forever continuous monitoring control channel, and HS-SCCH order also cannot activate DRX.
UE determines the DRX pattern (pattern) when DRX state:
HS-SCCH receives pattern and calculates according to formula below, and the Rx time during DRX is 1 subframe:
((2*CFN-HS_SCCH_DRX?Offset+subframe?number)MODHS_SCCH_DRX?cycle)＝0
Wherein, CFN is System Frame Number; Subframe number is the numbering of two subframes in a radio frames, and first subframe is that 0, the second subframe is 1; HS_SCCH_DRX cycle is that base station sends the cycle of HS-SCCH, unit subframe in DRX pattern; HS_SCCH_DRX Offset is the skew of subframe in DRX cycle, and the time that makes base station send the HS-SCCH of each UE is uniformly distributed, and the subframe position of transmission is determined by formula below, unit subframe.
Fig. 2 has provided HS-SCCH DRX Offset=6, HS-SCCH DRX cycle=4, and the example starting at CFN=1:
The transmission pattern of E-AGCH calculates according to formula below:
((2*CFN-E_AGCH_DRX?Offset+subframe?number)MOD?E_AGCH_DRXcycle)＝0
Wherein, CFN is System Frame Number (radio frames); Subframe number is the numbering of two subframes in a radio frames, and first subframe is that 0, the second subframe is 1; E_AGCH_DRX cycle is that base station sends the cycle of E-AGCH, unit subframe in DRX pattern; E_AGCH_DRX Offset is the skew of subframe in DRX cycle, and the time that makes base station send the E-AGCH of each UE is uniformly distributed, and the subframe position of transmission is determined by formula below, unit subframe.
Meet the CFN of formula above, UE can receive E-AGCH, HS-SCCH.
In sum, the parametric description of DRX is as follows:
About Enabling_Delay: must join, configure after Enabling_Delay radio frames after the DRX parameter in upper table, UE enters DRX state.Can be activated or deexcitation by HS-SCCH orders afterwards.Before Enabling_Delay radio frames, UE can continuous monitoring control channel.
About Inactivity_Threshold_for_HS_SCCH_DRX_cycle: can join, if configuration timer, when UE has received after HS-SCCH or HS-PDSCH, and after feedback HS-SICH, start this timer, in timer time, UE can receive continuously, if timer expiry, UE enters DRX, if UE has received HS-PDSCH and HS-SCCH in this timer, restarts so this timer after feeding back uplink HS-SICH.If timer is configuration not, can be understood as timer is 0.If Inactivity_Threshold_for_HS_SCCH_DRX_cycle set timer is endless, think and only have enabling delay just can make terminal enter DRX, once but scheduling, terminal will exit DRX, and forever continuous monitoring control channel, and HS-SCCH order also cannot activate DRX.
About E_AGCH_Inactivity_Monitor_Threshold: can join, if configuration timer, after UE would report TEBS to be 0, and start this timer received ACK on E-HICH after, in timer time, UE can receive E-AGCH continuously, if timer expiry, UE enters DRX.If UE sends SI separately under E-AGCH DRX state in Mac-e pdu/Mac-i pdu, and TEBS is wherein 0, timer is not restarted (if be originally not activated, do not start so) yet, if terminal has sent E-PUCH in DRX state, and carried TEBS > 0, terminal enters RX state immediately.If do not configure timer, according to current parameter configuration, even if the timer of E-AGCH DRX does not appear in DRX info, but this timer still in E-AGCH info, must join, so still can carry out DRX operation according to the mode of timer.If E_AGCH_Inactivity_Monitor_Threshold set timer is endless, think and only have enabling delay just can make terminal enter DRX, once but dispatch terminal or receive the TEBS > 0 of terminal to report, will be considered as terminal and exit DRX, and forever continuous monitoring control channel, and HS-SCCHorder also cannot activate DRX.For any scene, if terminal will enter RX state after sending TEBS > 0 automatically, terminal can be monitored E-AGCH continuously during TEBS > 0.
During single carrier HSUPA, because UE can not dispatched in base station on a carrier wave, therefore, E-AGCH is when TEBS is greater than 0, and in order to apply for resource transmission business, UE needs continuous monitoring control channel, and after multicarrier is introduced, DRX mechanism can be subject to the impact of multicarrier, influencing factor is as follows:
(1) under multicarrier due to HS-SICH (Shared Information Channel for HS-DSCH, for the shared information channel of HS-DSCH) and E-PUCH (E-DCH Physical Uplink Channel, E-DCH physical uplink channel) on a plurality of carrier waves, launch, if UE is in cell edge, UE power can be limited, if at this moment still use a plurality of carrier waves will affect channel quality, so now for the multicarrier UE that is positioned at cell edge, the portion of carriers in its a plurality of carrier waves now may not dispatched in base station.
(2) due to load reason, certain multicarrier UE can not be dispatched in base station on some carrier waves, although these carrier waves have been configured to this multicarrier UE.
The generation of above two kinds of situations, causes multicarrier UE when monitoring E-AGCH and HS-SCCH, to be subject to the impact of multicarrier, and existing protocol to this scene without any operation, therefore, need clear and definite treatment mechanism.

In order to realize in multicarrier system, the discontinuous reception of terminal to down control channel, in the embodiment of the present invention, terminal is obtained the discontinuous reception DRX parameter information that network side is the user configured down control channel of multicarrier; The situation that terminal is scheduled according to in-cache status and each carrier wave, safeguards the timer of corresponding carrier wave and carries out relevant DRX operation, wherein, the duration of timer is according to timer information setting in described DRX parameter information.In described DRX parameter information, timer information can be shared for all carrier waves of multicarrier user, can be also that multicarrier user's partial carrier wave is shared.
Shown in Figure 3, the method for the embodiment of the present invention comprises the following steps:
Step 301: terminal is obtained the discontinuous reception DRX parameter information that network side is the user configured down control channel of multicarrier.
The shared meaning refers to: during the RRC signal deployment of network, only configure a parameter, such as DRX timer duration, the DRX timer of each carrier wave uses this timer duration independently to create DRX timer.
Step 302: the situation that terminal is scheduled according to in-cache status and/or each carrier wave, safeguard the timer of corresponding carrier wave and carry out relevant DRX operation, wherein, the duration of timer is to set according to timer information in described DRX parameter information.
If the DRX of terminal in state of activation, can safeguard respectively as the DRX timer of the carrier wave of terminal configuration and carry out relevant DRX operation, the wherein carrier wave of corresponding one or several terminal of each DRX timer.
Described down control channel can comprise: strengthen the absolute grant channel E-AGCH of dedicated channel, or, HS-SCCH.
Below lift the implementation procedure of specific embodiment detailed description step 302:
The first situation: safeguard the timer of corresponding carrier wave in step 302 and carry out relevant DRX operation and can realize like this:
Any one DRX timer for terminal, before it is overtime, terminal is monitored continuously E-AGCH on carrier wave corresponding to this timer, if the timer expiry of any carrier wave, monitors and enters DRX state by the pattern monitoring E-AGCH setting the E-AGCH of carrier wave corresponding to timer described in this.Now, described down control channel can be E-AGCH, can be also HS-SCCH.
For example: the down control channel of take illustrates the implementation of the first situation as E-AGCH as example.
(1) if the size of buffer memory becomes and is greater than 0 from 0, terminal is restarted the timer of each carrier wave.
Here, if the size of buffer memory becomes and is greater than 0 from 0, terminal can directly be restarted the timer of each carrier wave, can be to be also greater than 0 schedule information SI to issue the timer of restarting each carrier wave after network side by containing buffer memory; Maybe can also receive the timer of restarting each carrier wave after the E-AGCH of network side scheduling; Maybe can also receive the timer of restarting each carrier wave after the E-HICH of the E-PUCH that carries SI of network side feedback.
(2) before timer expiry, on carrier wave corresponding to each timer, monitor continuously E-AGCH, if receive E-AGCH on corresponding carrier wave, restart the timer of this carrier wave; If the timer expiry of any carrier wave, monitors to the E-AGCH of this carrier wave the DRX state that enters.
The second situation: when described down control channel comprises E-AGCH, if the DRX of terminal is in state of activation, in step 302, safeguard the timer of corresponding carrier wave and carry out relevant DRX operation and can realize like this: before timer expiry, on carrier wave corresponding to each timer, monitor continuously E-AGCH, if the timer expiry of any carrier wave, the E-AGCH on this carrier wave monitors the DRX state that enters.
Can also realize like this:
Before timer expiry, on carrier wave corresponding to each timer, monitor continuously E-AGCH, if the timer expiry of any carrier wave, in current cache for being greater than at 0 o'clock, the E-AGCH on this carrier wave monitors the DRX state that enters, in current cache, be 0 o'clock, stop on this carrier wave and monitor E-AGCH, or stop on all carrier waves and monitor E-AGCH.
(1) if the size of buffer memory becomes and is greater than 0 from 0, terminal is restarted the timer of each carrier wave.
(2) before timer expiry, on carrier wave corresponding to each timer, monitor continuously E-AGCH, if receive E-AGCH on corresponding carrier wave, restart this carrier wave timer; If the timer expiry of any carrier wave, in current cache for being greater than at 0 o'clock, the E-AGCH on this carrier wave monitors the DRX state that enters; In current cache, be 0 o'clock, stop on this carrier wave and monitor E-AGCH, or stop on all carrier waves and monitor E-AGCH.
Wherein, if the timer expiry of any carrier wave stops at the step of monitoring E-AGCH on this carrier wave and specifically can realize like this:
Directly stop on this carrier wave and monitor E-AGCH; Or terminal was fed back on any carrier wave that to carry this buffer memory be empty SI and is stopped on this carrier wave and monitor E-AGCH to network side and after receiving the confirmation ACK of E-HICH of network side; Or, terminal was fed back this buffer memory on this carrier wave or on any carrier wave of this terminal to be 0 SI start another timer to network and after receiving the ACK of E-HICH of network side, until described another timer expiry is all no longer received that E-AGCH stops on this carrier wave and monitored E-AGCH.
If the timer expiry of any carrier wave, stopping at the step of monitoring E-AGCH on all carrier waves can realize like this:
Directly stop on all carrier waves and monitor E-AGCH; Or terminal was fed back on this carrier wave or on any carrier wave of this terminal that to carry this buffer memory be 0 SI and is stopped on all carrier waves and monitor E-AGCH to network side and after receiving the ACK of E-HICH of network side.
In embodiments of the present invention, can on corresponding carrier wave, receive E-AGCH, and after having fed back E-PUCH, restart the timer of this carrier wave; Also can on corresponding carrier wave, receive E-AGCH, and having fed back E-PUCH and having received after the confirmation of E-HICH, restart the timer of this carrier wave.In the time of can also receiving E-AGCH on corresponding carrier wave, directly restart the timer of this carrier wave.
The third situation: when described down control channel comprises E-AGCH, operate if the DRX of terminal in state of activation, safeguards the timer of corresponding carrier wave and carries out relevant DRX, comprising:
If timer expiry corresponding to specific carriers of setting enters DRX state to the monitoring of E-AGCH in described specific carriers; Or, if the timer expiry of the specific carriers of setting, and the buffer memory of current terminal is greater than 0, monitor continuously the E-AGCH of described specific carriers, if the timer expiry of the specific carriers of setting, and the buffer memory of current terminal is 0, the E-AGCH of described specific carriers monitors the DRX state that enters.
If timer corresponding on nonspecific carrier wave is not overtime, on described nonspecific carrier wave, monitor continuously E-AGCH.
If the timer expiry of any carrier wave in nonspecific carrier wave, in current cache for being greater than at 0 o'clock, the E-AGCH on described nonspecific carrier wave monitors the DRX state that enters; In current cache, be 0 o'clock, stop on described nonspecific carrier wave or on all nonspecific carrier waves and monitor E-AGCH; Or,
If the timer expiry of any carrier wave in nonspecific carrier wave, stops monitoring the E-AGCH on described nonspecific carrier wave or stops monitoring the E-AGCH on all nonspecific carrier waves.
In implementation procedure, for the timer of specific carriers, if terminal buffers is greater than at 0 o'clock, timer can not start, and timer only just starts after buffer memory is sky.
And, if the timer expiry of the specific carriers of setting, and be 0 o'clock at the buffer memory of current terminal, the E-AGCH monitoring for described specific carriers can directly enter DRX state; Also can be by after to carry buffer memory be empty SI informing network, for the E-AGCH of described specific carriers, monitor the DRX state that enters; Can also by carrying buffer memory, be empty SI informing network and receive after the confirmation of network, for the E-AGCH of described specific carriers, monitor the DRX state that enters.
For example:
If the size of buffer memory becomes and is greater than 0 from 0, terminal is restarted the timer of each carrier wave;
If timer expiry corresponding to specific carriers of setting enters DRX state to the monitoring of E-AGCH in described specific carriers;
If timer corresponding on nonspecific carrier wave is not overtime, on described nonspecific carrier wave, monitor continuously E-AGCH, and if receive E-AGCH, restart the timer of described nonspecific carrier wave; If the timer expiry of any carrier wave in nonspecific carrier wave, in current cache for being greater than at 0 o'clock, the E-AGCH on described nonspecific carrier wave monitors the DRX state that enters; In current cache, be 0 o'clock, stop on described nonspecific carrier wave or on all nonspecific carrier waves and monitor E-AGCH.
Stop on described nonspecific carrier wave or on all nonspecific carrier waves, monitor E-AGCH and can realize like this:
Directly on described nonspecific carrier wave or on all nonspecific carrier waves, monitor E-AGCH; Or terminal was fed back on this carrier wave or on any carrier wave of this terminal that to carry this buffer memory be 0 SI and is stopped on described nonspecific carrier wave or on all nonspecific carrier waves and monitor E-AGCH to network side and after receiving the ACK of E-HICH of network side.
On described nonspecific carrier wave, monitor continuously E-AGCH, can, receiving E-AGCH and feeding back after E-PUCH, restart the timer of this carrier wave; Also can on described nonspecific carrier wave, monitor E-AGCH continuously, if receive E-AGCH and having fed back E-PUCH and having received after the confirmation of E-HICH, restart the timer of this carrier wave; The in the situation that of can also receiving E-AGCH on described nonspecific carrier wave, directly restart the timer of this carrier wave.
In above-mentioned three examples, in step (1), if the size of buffer memory becomes and is greater than at 0 o'clock from 0, terminal can directly be restarted the timer of each carrier wave, or terminal can be to be greater than 0 SI to issue the timer of restarting each carrier wave after network side by containing buffer memory.Or terminal is to be greater than 0 SI to issue network side and receive the timer of restarting its all carrier waves after network is responded by containing buffer memory, wherein, network is responded and is referred to the confirmation of E-HICH or the scheduling authorization information of E-AGCH.
Lift specific embodiment below and describe technical scheme of the present invention in detail.
It should be noted that, when the DRX of UE is in deactivation status, UE will monitor E-AGCH channel continuously.When the DRX of UE is in state of activation, UE will carry out DRX operation according to following mode.
Embodiment 1:
Shown in Figure 4, the specific implementation process of the embodiment of the present invention 1 is as follows:
Step 401: observe TEBS, and judge the size of TEBS, if TEBS becomes and is greater than 0 from 0, perform step 402, otherwise, can continue to perform step 401.
Step 402: by the DRX timer restart of all carrier waves.
At TEBS from 0 to being greater than 0, UE is restarted the timer of each carrier wave, or the SI with TEBS > 0 is issued to the timer restart of all carrier waves after network side, or after receiving the E-AGCH of network scheduling, restart, or receive after feedback is carried the E-HICH of E-PUCH of SI and restart.
Step 403: the timer of safeguarding each carrier wave according to the scheduling situation of all carrier waves.
Step 404: judged whether timer expiry, if the timer expiry of any one carrier wave, the E-AGCH of this carrier wave of timer expiry monitors the DRX state that enters, otherwise, on this carrier wave, E-AGCH is monitored continuously.
Here, before timer expiry, the carrier wave that this timer is corresponding will be monitored E-AGCH continuously, on this carrier wave, receive after E-AGCH, the timer of this carrier wave will be restarted (or just restarting after having fed back E-PUCH), after the timer expiry of carrier wave, the E-AGCH of this carrier wave monitors the DRX state that enters arbitrarily.

In embodiment 1, each carrier wave can independently enter the state that DRX receives E-AGCH.When network for load or the consideration of other factors when some carrier waves are not dispatched UE, UE can realize reasonable power saving effect.Therefore, the feature of this embodiment is: each starts the multicarrier UE of DRX function, if configured a plurality of work carrier waves, the DRX timer independent maintenance of each carrier wave, so that each carrier wave can independently enter DRX state, realizes good power saving effect.
Embodiment 2:
Shown in Figure 5, the specific implementation of the present embodiment is as follows:
Step 501: observe TEBS, and judge the size of TEBS, if TEBS becomes and is greater than 0 from 0, perform step 502, otherwise, can continue to perform step 501.
Step 502: by the DRX timer restart of all carrier waves.
TEBS is from 0 to the timer that is greater than 0, UE and restarts each carrier wave, or the SI with TEBS > 0 issued to the timer restart of all carrier waves after network side.
Step 503: the timer of safeguarding each carrier wave according to the scheduling situation of all carrier waves.
Step 504: judged whether timer expiry, if the timer expiry of any one carrier wave stops monitoring the E-AGCH of this carrier wave; Or, at the timer expiry of any one carrier wave, continue judgement TEBS, if TEBS is greater than 0, the E-AGCH of this carrier wave is monitored and enters DRX state, if TEBS=0, this carrier wave stops monitoring E-AGCH, if timer is not overtime, monitors continuously the E-AGCH of this carrier wave.
In the present embodiment, before timer expiry, the carrier wave that this timer is corresponding will be monitored E-AGCH continuously, on this carrier wave, receive after E-AGCH, the timer of this carrier wave will be restarted and (or just be restarted after having fed back E-PUCH, or after receiving the confirmation of E-HICH, restart), arbitrarily after the timer expiry of carrier wave, can observe TEBS, if TEBS > 0, the E-AGCH of this carrier wave monitors the DRX state that enters, if TEBS=0, stop monitoring this carrier wave E-AGCH (or UE on this carrier wave or the SI that fed back this TEBS=0 on any carrier wave of this UE to network and receive E-HICH (the E-DCH Hybrid ARQ Indicator Channel of network side, E-DCH mixing automatic repeat request indicating channel, ARQ, Automatic Repeat Request HARQ) ACK just stops monitoring later, or UE on this carrier wave or the SI that fed back this TEBS=0 on any carrier wave of this UE to network and after receiving the ACK of E-HICH of network side, start timer, until timer expiry all no longer receives that E-AGCH just stops monitoring).
It should be noted that, the SI of this TEBS=0 refers to, after the buffer memory of UE becomes 0, UE sent SI informing network side on a certain carrier wave, and during to the timer expiry of other carrier waves, the buffer memory of UE does not change, and other carrier waves also can stop monitoring E-AGCH according to the condition of this TEBS=0 so.
Certainly, the mode that stops monitoring also has a kind of implementation below:
TEBS is from zero to being greater than 0, UE is restarted the timer timer restart of all carrier waves after network side (or the SI with TEBS > 0 is issued) of each carrier wave, before timer expiry, the carrier wave that this timer is corresponding will be monitored E-AGCH continuously, on this carrier wave, receive after E-AGCH, this carrier wave timer will restart (or just restarting after having fed back E-PUCH), arbitrarily after the timer expiry of carrier wave, observe TEBS, if TEBS > 0, the E-AGCH of this carrier wave monitors the DRX state that enters, if TEBS=0, stop monitoring all carrier waves E-AGCH (or UE on this carrier wave or the SI that fed back TEBS=0 on any carrier wave of this UE to network and the E-AGCH that just stops all carrier waves after receiving the ACK of E-HICH of network side monitor).
Embodiment 2 is E-AGCH that UE can discontinuous each carrier wave of monitoring when having transfer of data, when UE buffer memory can stop monitoring control channel E-AGCH, more power saving of UE like this when empty.And safeguard that timer is minimum.Therefore, the feature of this scheme is: during buffer memory non-NULL, each carrier wave independent maintenance DRX timer of UE, so that each carrier wave of UE can be independent enter DRX, the DRX timer expiry of any one carrier wave and UE buffer memory are empty, the E-AGCH that UE can stop this carrier wave or all carrier waves monitors, and realizes best power saving effect.
Embodiment 3:
Shown in Figure 6, the specific implementation process of the present embodiment is as follows:
Step 601: observe TEBS, and judge the size of TEBS, if TEBS becomes and is greater than 0 from 0, perform step 602, otherwise, can continue to perform step 601.
Step 602: by the DRX timer restart of all carrier waves.
TEBS is from zero to the timer that is greater than 0, UE and restarts each carrier wave, or the SI with TEBS > 0 issued to the timer restart of all carrier waves after network side.
Step 603: the timer of safeguarding each carrier wave according to the scheduling situation of all carrier waves.
Step 604: for specific carriers, monitor E-AGCH and enter DRX state during timer expiry, the timer expiry for any carrier wave in other carrier waves, stops monitoring E-AGCH this carrier wave or every other carrier wave; Or, to with other carrier waves in arbitrarily during the timer expiry of carrier wave, continue judgement TEBS, if TEBS > 0, the E-AGCH of this carrier wave monitors and enters DRX state, if TEBS=0 stops monitoring E-AGCH for this carrier wave or every other carrier wave, if timer is not overtime, monitor continuously the E-AGCH of this carrier wave.
In the present embodiment, before timer expiry, the carrier wave that this timer is corresponding will be monitored E-AGCH continuously, on this carrier wave, receive after E-AGCH, the timer of this carrier wave will be restarted (or just restarting after having fed back E-PUCH), one or more specific carrier wave for certain, after the timer expiry of this carrier wave, the E-AGCH of this carrier wave monitors the DRX state that enters; For other carrier waves, after the timer expiry of any one carrier wave of described other carrier waves, stop monitoring described any one carrier wave or stop monitoring all described other carrier waves, or, observe TEBS, if TEBS > 0, the E-AGCH of this any one carrier wave monitors the DRX state that enters, if TEBS=0, stop monitoring the E-AGCH of this carrier wave or every other carrier wave, or UE on this carrier wave or the SI that fed back this TEBS=0 on any carrier wave of this UE to network and after receiving the ACK of E-HICH of network side, just stop monitoring.
In the present embodiment, when TEBS=0, retain one or partial carrier wave and enter DRX state, other carrier waves stop monitoring, and are so both base station scheduling reservation flexibility, can realize again the effect of power saving, are a kind of modes of compromise.
