Description

Dispatching method, equipment and system

Technical field

The present invention relates to the communications field, particularly a kind of dispatching method, equipment and system.

Background technology

in radio communication, HS-SCCH(High Speed Shared Control Channel can be passed through in the base station, High-Speed Shared Control Channel) and HS-PDSCH(High Speed Physical Downlink Shared Channel, high-speed physical downlink shared channel (HS-PDSCH)) to HSDPA(High Speed Downlink Packet Access, the high speed downlink packet access) user dispatches, comprise again more special DC HSDPA(Dual-Carrier High Speed Downlink Packet Access in this HSDPA user, two carrier wave high speed downlink packet accesses) user.

When dispatching for DC HSDPA user:

After DC HSDPA user accesses the residential quarter of supporting DC HSDPA technology, can receive simultaneously from the information of the HS-SCCH of two alien-frequency districts and the data of HS-PDSCH, one in these two alien-frequency districts is the main plot, by the main carrier transmission of data signals, another is auxiliary residential quarter, by auxiliary carrier transmission data-signal.Simultaneously, DC HSDPA user is by up HS-DPCCH(High Speed Dedicated Physical Control Channel, Dedicated Physical Control Channel) with ACK(Acknowledgement, confirmation) and CQI(Channel Quality Indicator, the channel quality indication) information is returned the base station of feeding, complete physical layer HARQ(Hybrid Automatic Repeat Request, the mixed automatic retransfer request) function.

Support the UE(User Equipment of DC HSDPA technology, subscriber equipment) need to monitor simultaneously maximum 6 HS-SCCH from two alien-frequency districts, the power consumption of UE is larger; In addition, introduce again MIMO(Multiple Input Multiple Output on the basis of DC HSDPA technology, multiple-input, multiple-output) after technology, up HS-DPCCH can take more ascending resource, has increased the load of base station side.

For the problems referred to above, when lower the or load base station reaches max threshold in the volume of transmitted data of UE, can issue the deexcitation instruction by HS-SCCH is SC HSDPA(Single-Carrier High Speed Downlink Packet Access with the status modifier of UE, the access of single carrier high speed downlink packet) state, it is auxiliary carrier wave deexcitation, only keep the transmission that main carrier carries out data-signal, reach the purpose that reduces UE power consumption and reduce load of base station.After auxiliary carrier wave deexcitation, can also issue activation instruction by HS-SCCH UE is reactivated the state into DC HSDPA, i.e. auxiliary carrier activation improves the speed of UE.

When dispatching for HSDPA user:

HSDPA User support HS-SCCH less operation(follows without HS-SCCH) pattern, the basic principle of HS-SCCH less operation is to reduce the transmission of following channel HS-SCCH of HSDPA low speed business, namely do not need to follow HS-SCCH when HS-PDSCH new biography data, need to follow the HS-SCCH new model of HS-SCCH during data retransmission.

When, descending transmission retransmission rate better at wireless environment is low, under HS-SCCH less operation pattern, do not need to follow HS-SCCH during due to the new biography data, HS-SCCH power can be saved in the base station, for weak overlay area, because the HS-SCCH channel may consume cell power more than 10%, so can promote the throughput of weak overlay area after HS-SCCH power saves, enlarge cell coverage area; Simultaneously, reduce the transmission of HS-SCCH and can save the HS-SCCH code source, can be at a TTI(Transmission Time Interval, Transmission Time Interval thereby descending) in the more UE of scheduling, improve downlink capacity; But, due to the UE number increase of descending scheduling, up HS-DPCCH feedback becomes many, so ascending load can have increased slightly; Concerning UE, after using HS-SCCH less operation pattern, UE need to carry out blind Detecting to the HS-PDSCH channel, therefore needs the original more power of consumption rate, and power consumption is large.

At present, can issue the deexcitation instruction by HS-SCCH is non-HS-SCCH less operation pattern with the status modifier of UE, reaches the purpose that reduces UE power consumption and reduce the base station ascending load; Equally, also can issue activation instruction by HS-SCCH the state of UE is reactivated the pattern into HS-SCCH less operation, reach the purpose that promotes cell capacity.

In sum, DC HSDPA user auxiliary carrier activation deexcitation technology and HSDPA user HS-SCCH less operation activate the deexcitation technology all can in the situation that do not increase space interface signaling expense fast and flexible realize the UE status modifier.

In realizing process of the present invention, the inventor finds that there is following shortcoming at least in prior art:

No matter be the auxiliary carrier activation deexcitation of DC HSDPA user technology, or HSDPA user HS-SCCH less operation activates the deexcitation technology, send the instruction of activation or deexcitation by HS-SCCH when the base station after, the state of UE can not change immediately.Send instructions to from the base station in the interval during this period of time of UE state change, the behavior of base station side and UE side may be inconsistent, in such cases, the situation of lost data frames easily occurs, and then make the behavior of base station side and the state of UE the inconsistent of longer time occur, cause performance loss.

Embodiment

For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.

Embodiment one

The embodiment of the present invention provides a kind of dispatching method, and referring to Fig. 1, method flow is specific as follows:

101: send status command to HSDPA UE, this status command comprises activation instruction or deexcitation instruction;

102: whether the state that judges this UE changes;

103: before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy.

Wherein, this default scheduling strategy guarantees that the descending scheduling behavior is consistent with the state of this UE.

The method that the embodiment of the present invention provides, in the time interval before changing by the state from the transmission status command to UE, carry out descending scheduling for this UE according to default scheduling strategy, clear and definite base station sends the behavior of controlling equipment side and UE side after the instruction of activation or deexcitation by HS-SCCH, the descending scheduling behavior of controlling equipment is consistent with the state of UE, has improved the performance of system.

Embodiment two

The embodiment of the present invention provides a kind of dispatching method, the method is except being applicable to WCDMA(Wideband Code Division Multiple Access, Wideband Code Division Multiple Access (WCDMA)) and TDSCDMA(Time Division-Synchronous Code Division Multiple Access, the CDMA (Code Division Multiple Access) that time-division is synchronous) outside system, can also be applied to other communication systems.The embodiment of the present invention only base station in the WCDMA describes as example according to R9 release protocol scheduling DC HSDPA user, but is not limited to this.

Referring to Fig. 2, method flow is specific as follows:

201: send status command to DC HSDPA UE, this status command comprises auxiliary carrier activation instruction or auxiliary carrier wave deexcitation instruction;

Wherein, because the application scenarios of the present embodiment is for the DC HSDPA user in the R9 release protocol of WCDMA, that is to say, when UE was DC HSDPA subscriber equipment, this status command specifically comprised auxiliary carrier activation instruction or auxiliary carrier wave deexcitation instruction.

Particularly, can be the network equipment, such as the base station, send status command by HS-SCCH to UE, the auxiliary carrier wave of activation or deexcitation UE.In the WCDMA system, when sending auxiliary carrier activation instruction to UE, be the SC HSDPA state of UE will be activated to be DC HSDPA state; When sending auxiliary carrier wave deexcitation instruction to UE, be to be SC HSDPA state with the DC HSDPA state deexcitation of UE.Be understandable that, in process, status command can be only a kind of in auxiliary carrier activation instruction or auxiliary carrier wave deexcitation instruction, and follow-up flow process is substantially similar.In the description of the embodiment of the present invention, be only easy in order to narrate with both purposes of describing of putting together.

202: whether the state that judges this UE changes, and if not, execution in step 203, and if so, execution in step 204;

Wherein, whether the state that judges this UE changes, be specifically as follows according to the confirmation information that whether gets this UE and judge whether the state of this UE changes, (do not get feedback information if get the feedback information of this UE, just certainly can not get confirmation yet), although or the feedback information that gets, this feedback information is not ACK(Acknowledgement, confirmation), the state that judges this UE does not change.

Particularly, for this step, at first can obtain by up HS-DPCCH the feedback information of this UE, this feedback information may be ACK, NACK(Negative Acknowledgement, deny information) and DTX(Discontinuous Transmission, discontinuous transmission) in a kind of.Feedback information can be stored in the base station and send in the corresponding uplink frame of frame of status command by HS-SCCH.If do not get feedback information, judge that the auxiliary Carrier State of this UE does not change; If the feedback information that gets is NACK or DTX(is not namely ACK), judge also that the auxiliary Carrier State of this UE does not change; Be ACK if get feedback information, judge that the auxiliary Carrier State of this UE changes.

203: if the state of this UE does not change, before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy, after the state of this UE changes, execution in step 204;

Wherein, if the state of this UE does not change, before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy, this default scheduling strategy guarantees that the scheduling behavior on auxiliary carrier wave is consistent with the auxiliary Carrier State of this UE.Default scheduling strategy herein is specially:

Do not carry out the descending scheduling for this UE; Or,

Carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE; Or,

Only carry out descending scheduling for this UE at main carrier.

Particularly, do not carry out the descending scheduling for this UE, namely from sending status command to UE within the time interval of the auxiliary Carrier State change of UE, base station side does not issue the data of any scheduling by main carrier and auxiliary carrier wave pin to this UE.Simultaneously, receive the uplink frame that this UE sends.

Carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE, namely from sending status command to UE within the time interval of the auxiliary Carrier State change of UE, base station side issues data according to original scheduling mode before sending status command to this UE to this UE.Simultaneously, receive the uplink frame that this UE sends.

Only carry out descending scheduling for this UE at main carrier, namely from sending status command to UE within the time interval that the auxiliary Carrier State of UE changes, base station side is only dispatched this UE by main carrier, issues data to this UE.Simultaneously, receive the uplink frame that this UE sends.

In actual applications, can select any one in above-mentioned three kinds of default scheduling strategies to implement.

Further, the state of UE does not change the two kinds of situations that comprise:

The first situation is not get feedback information, in such cases, continues to obtain feedback information;

The second situation is to have got feedback information but be not ACK, in such cases, can repeat the step that sends status command to UE.

In the second situation, after the number of times that repeats the step that sends status command to UE surpasses maximum retransmission, can carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE.Wherein, the embodiment of the present invention does not specifically limit maximum retransmission, can set according to actual conditions, as being made as 4 times.

In a word, the feedback information that no matter does not get feedback information or get is NACK or DTX, or repeat in the middle of the process of UE transmission status command, the state of this UE does not all change, before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy, and after the state of this UE changes, execution in step 204.

204: if the state of this UE changes, carry out descending scheduling for this UE according to the state of status command appointment, flow process finishes;

Particularly, in case determine that the state of UE changes, the descending scheduling for this UE according to auxiliary carrier activation or the deactivation status of status command appointment, is carried out in the base station.Such as, if the auxiliary carrier wave after the UE state changes is state of activation, carry out descending scheduling for this UE by main carrier and auxiliary carrier wave; If the auxiliary carrier wave after the UE state changes is deactivation status, carry out descending scheduling for this UE by main carrier.

On the other hand, after the state of UE changes, carry out up HS-DPCCH frame according to the state after changing immediately and send.

Further, for the method that the embodiment of the present invention provides, concrete example is described as follows:

The time that each frame takies is 1 TTI, the 1TTI=3slot(time slot).The base station issues a bar state instruction fully needs 1 TTI, and after 4 TTI after status command issues fully, UE returns to feedback information.After sending status command for a certain UE, whether be that ACK judges whether the state of UE changes according to the feedback information of UE, divide following two kinds of situations to process according to timing relationship:

The first situation: feedback information is ACK, referring to Fig. 3:

At the 1st TTI, send status command by HS-SCCH to UE;

Do not get feedback information in the 1st to the 5th TTI, in the interval, the state of UE does not change during this period of time, carries out descending scheduling for this UE according to default scheduling strategy;

At the 6th TTI, the base station gets the feedback information of UE, obtains frame corresponding to the status command with HS-SCCH that this feedback information sends by up HS-DPCCH from UE, and is judged as ACK;

At the 6th TTI, the base station begins auxiliary Carrier State according to the status command appointment and carries out descending scheduling for this UE;

Carrying out up HS-DPCCH frame according to the state after changing immediately after the auxiliary Carrier State of UE changes sends.

The second situation: feedback information is NACK or DTX, referring to Fig. 4:

At the 1st TTI, send status command by HS-SCCH to UE;

At the 6th TTI, the base station gets the feedback information of UE, obtains frame corresponding to the status command with HS-SCCH that this feedback information sends by up HS-DPCCH from UE, and is judged as NACK or DTX;

Retransmit status command at the 7th TTI to UE;

Be natural number more than or equal to 1 at the 6th * N+6(N, N represents number of retransmissions) individual TTI base station gets the feedback information of UE, this feedback information, judges this feedback information by obtaining frame corresponding to the status command with HS-SCCH of up HS-DPCCH transmission from UE:

If be judged as ACK, process by the first situation, be namely natural number more than or equal to 1 at the 6th * N+6(N, N represents number of retransmissions) individual TTI base station begins state according to the status command appointment and carries out descending scheduling for this UE, carries out the transmission of frame by up HS-DPCCH according to the state after changing immediately after the state of this UE changes;

If be judged as NACK or DTX, continue to retransmit status command to UE, wherein from the 1st TTI to receiving that ACK(is that the state of UE changes) or reach maximum retransmission during, all carry out descending scheduling for this UE according to default scheduling strategy.

After the number of times that retransmits surpasses maximum retransmission, carry out descending scheduling for this UE according to send original scheduling mode before status command to UE.

The method that the embodiment of the present invention provides, in the time interval before changing by the state from the transmission status command to UE, carry out descending scheduling for this UE according to default scheduling strategy, clear and definite base station sends the behavior of controlling equipment side and UE side after the instruction of activation or deexcitation by HS-SCCH, the descending scheduling behavior of controlling equipment is consistent with the state of UE, improved the performance of system, specific as follows:

When default strategy is from sending status command within the time interval of the state change of UE, when not carrying out the descending scheduling for this UE, simplify system's realization, avoided the re-transmission that causes after loss that the auxiliary Carrier State of base station side scheduling and UE may the inconsistent existing Frame that causes and loss; Simultaneously, in the interval during this period of time of not carrying out for the descending scheduling of this UE, other UE can be dispatched in the base station, have ensured descending throughput and the Systems balanth of base station.Be applicable to auxiliary carrier activation deexcitation scene.

When default strategy is from sending status command within the time interval of the state change of UE, when sending original scheduling mode before status command to UE and carry out descending scheduling for this UE, make base station side remain consistent with reception with the state of UE with data dispatch on auxiliary carrier wave at main carrier; Simultaneously, carry out also having reduced for the descending scheduling of this UE the complexity that base station side is processed according to original scheduling mode send status command to UE before, preferably in situation, the data of UE side are downloaded impression and also can not descended at channel condition.Mainly be applicable to auxiliary carrier wave deexcitation scene.

When default strategy is from sending status command within the time interval of the state change of UE, only when main carrier carries out descending scheduling for this UE, no matter activate or the auxiliary carrier wave of deexcitation, UE can be not influenced by the data message of the up HS-DPCCH transmission of main carrier, be the ACK information that base station side can correctly be resolved single carrier, also can compatible ACK information of resolving the main carrier of two carrier waves, make the transmission of information not be subjected to base station side and inconsistent impact of UE side state; Simultaneously, before having solved after instruction issues UE response ACK, the subsequent treatment risk of data dispatching is surveyed in the base station, has promoted the reliability of system.Be applicable to auxiliary carrier activation and deexcitation scene.

Embodiment three

The embodiment of the present invention provides a kind of dispatching method, and the method can also be applied to other communication systems except being applicable to WCDMA and TDSCDMA system.The embodiment of the present invention only base station in the WCDMA describes as example according to R7 release protocol scheduling HSDPA user (comprising DC HSDPA user), but is not limited to this.

Referring to Fig. 5, method flow is specific as follows:

501: send status command to HSDPA UE, this status command comprises HS-SCCH less operation mode activation instruction or HS-SCCH less operation pattern deexcitation instruction;

Wherein, because the application scenarios of the present embodiment is for the HSDPA user in the R7 release protocol of WCDMA, that is to say, when UE was the HSDPA subscriber equipment, this status command specifically comprised HS-SCCH less operation mode activation instruction or HS-SCCH less operation pattern deexcitation instruction.

Particularly, can be the network equipment, such as the base station, send status command by HS-SCCH to UE, the HS-SCCH less operation pattern of activation or deexcitation UE.In the WCDMA system, when sending the instruction of HS-SCCH less operation mode activation to UE, be to be HS-SCCH less operation pattern with UE from original mode activation; When sending HS-SCCH less operation pattern deexcitation instruction to UE, be to be original pattern with UE from the deexcitation of HS-SCCH less operation pattern.Under HS-SCCH less operation pattern, UE both can be according to HS-SCCH less operation mode receive data when the state of UE, also can be according to original mode, i.e. and non-HS-SCCH less operation mode receive data.If but the state of UE under non-HS-SCCH less operation pattern, UE is according to non-HS-SCCH less operation mode receive data so.Therefore, the base station adopts HS-SCCH less operation mode or original mode can dispatch transmission for the UE that is under HS-SCCH less operation pattern; And for the UE that is under non-HS-SCCH less operation pattern, adopt original mode to dispatch transmission.

Be understandable that, in process, status command can be only a kind of in HS-SCCH less operation mode activation instruction or HS-SCCH less operation pattern deexcitation instruction, and follow-up flow process is substantially similar.In the description of the embodiment of the present invention, be only easy in order to narrate with both purposes of describing of putting together.

502: whether the state that judges this UE changes, and if not, execution in step 503, and if so, execution in step 504;

Particularly, for this step, at first can obtain by up HS-DPCCH the feedback information of this UE, this feedback information may be ACK or DTX.Feedback information can be stored in the base station and send in the corresponding uplink frame of frame of status command by HS-SCCH.If do not get feedback information, judge that the HS-SCCH less operation mode state of this UE does not change; If the feedback information that gets is DTX(is not namely ACK), judge also that the HS-SCCH less operation mode state of this UE does not change; Be ACK if get feedback information, judge that the HS-SCCH less operation mode state of this UE changes.

503: if the state of this UE does not change, before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy, after the state of this UE changes, execution in step 504;

Wherein, if the state of this UE does not change, before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy, this default scheduling strategy guarantees that descending scheduling behavior is consistent with the HS-SCCH less operation pattern of this UE employing.Default scheduling strategy herein is specially:

Do not carry out the descending scheduling for this UE; Or,

Carry out descending scheduling for this UE according to non-HS-SCCH less operation pattern.

Particularly, do not carry out the descending scheduling for this UE, namely from sending status command to UE within the time interval of the HS-SCCH less operation mode state change of UE, base station side is no longer dispatched transmission processing to this UE.Simultaneously, receive the uplink frame that this UE sends.

Carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE, namely from sending status command to UE within the time interval of the HS-SCCH less operation mode state change of UE, base station side issues data according to original scheduling mode before sending status command to this UE to this UE.Simultaneously, receive the uplink frame that this UE sends.

Carry out descending scheduling for this UE according to non-HS-SCCH less operation pattern, namely from sending status command to UE within the time interval of the HS-SCCH less operation mode state change of UE, base station side is dispatched this UE according to non-HS-SCCH less operation pattern (being original mode), issues data to this UE.Simultaneously, receive the uplink frame that this UE sends.

In a word, the feedback information that no matter does not get feedback information or get is DTX, or repeat in the middle of the process of UE transmission status command, the state of this UE does not all change, before the state of this UE changes, carry out descending scheduling for this UE according to default scheduling strategy, and after the state of this UE changes, execution in step 504.

504: if the state of this UE changes, carry out descending scheduling for this UE according to the state of status command appointment, flow process finishes;

Particularly, in case determine that the state of UE changes, the descending scheduling for this UE according to HS-SCCH less operation pattern or the non-HS-SCCH less operation pattern of status command appointment, is carried out in the base station.Such as, if be HS-SCCH less operation pattern after the UE state changes, can adopt HS-SCCH less operation mode or original mode to carry out descending scheduling for this UE; If be non-HS-SCCH less operation pattern after the UE state changes, adopt original mode to carry out descending scheduling for this UE.

The first situation: feedback information is ACK, referring to Fig. 3:

At the 1st TTI, send status command by HS-SCCH to UE;

At the 6th TTI, the base station begins HS-SCCH less operation mode state according to the status command appointment and carries out descending scheduling for this UE;

Carrying out up HS-DPCCH frame according to the state after changing immediately after the HS-SCCH less operation mode state of UE changes sends.

The second situation: feedback information is DTX, referring to Fig. 4:

At the 1st TTI, send status command by HS-SCCH to UE;

At the 6th TTI, the base station gets the feedback information of UE, obtains frame corresponding to the status command with HS-SCCH that this feedback information sends by up HS-DPCCH from UE, and is judged as DTX;

Retransmit status command at the 7th TTI to UE;

If be judged as DTX, continue to retransmit status command to UE, wherein from the 1st TTI to receiving that ACK(is that the state of UE changes) or reach maximum retransmission during, all carry out descending scheduling for this UE according to default scheduling strategy.

When default strategy is from sending status command within the time interval of the state change of UE, when not carrying out the descending scheduling for this UE, simplified system's realization, make the data dispatch of base station side remain consistent with reception with the UE state, to such an extent as to avoided the loss of the Frame that may occur to cause high-rise the re-transmission; Simultaneously, base station side can be dispatched other UE within the time period of not dispatching this UE, improves the base station down throughput, has promoted systematic function.

When default strategy be from sending in the time interval that status command changes to the state of UE, when sending original scheduling mode before status command to UE and carry out descending scheduling for this UE, reduced as far as possible the complexity of base station side processing; Before UE returns to ACK, change is not made in the scheduling of UE, preferably in situation, the throughput of residential quarter and power system capacity can not descend at channel condition.

when default strategy is from sending status command within the time interval of the state change of UE, when carrying out descending scheduling for this UE according to non-HS-SCCH less operation pattern, no matter the UE state is to be transformed into non-HS-SCCH less operation pattern from HS-SCCH less operation pattern, or be transformed into HS-SCCH less operation pattern from non-HS-SCCH less operation pattern, UE can carry out the data receiver of non-HS-SCCH less operation mode (being original mode), avoid like this adopting HS-SCCH less operation mode to dispatch to be sent in and activated the frame losing that may occur in deactivation process.

Embodiment four

Judge module 602 is used for judging whether the state of this UE changes after sending module 601 sends status command to HSDPA UE;

Scheduler module 603 was used for before the state of judge module 602 these UE of judgement changes, and carried out descending scheduling for this UE according to default scheduling strategy, and this default scheduling strategy guarantees that descending scheduling behavior is consistent with the state of this UE.

Wherein, when this UE was DC HSDPA subscriber equipment, sending module 601 specifically comprised auxiliary carrier activation instruction or auxiliary carrier wave deexcitation instruction to the status command that this UE sends.When sending auxiliary carrier activation instruction to UE, be the SC HSDPA state of UE will be activated to be DC HSDPA state; When sending auxiliary carrier wave deexcitation instruction to UE, be to be SC HSDPA state with the DC HSDPA state deexcitation of UE.

Correspondingly, should guarantee that the scheduling behavior on auxiliary carrier wave was consistent with the auxiliary Carrier State of this UE by default scheduling strategy, scheduler module 603 carry out for the concrete mode of the descending scheduling of this UE according to the scheduling strategy of presetting be: do not carry out the descending scheduling for this UE; Or, carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE; Or, only carry out descending scheduling for this UE at main carrier.Particularly, do not carry out the descending scheduling for this UE, namely from sending status command to UE within the time interval of the auxiliary Carrier State change of UE, base station side does not issue the data of any scheduling by main carrier and auxiliary carrier wave pin to this UE.Simultaneously, receive the uplink frame that this UE sends.Carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE, namely from sending status command to UE within the time interval of the auxiliary Carrier State change of UE, base station side issues data according to original scheduling mode before sending status command to this UE to this UE.Simultaneously, receive the uplink frame that this UE sends.Only carry out descending scheduling for this UE at main carrier, namely from sending status command to UE within the time interval that the auxiliary Carrier State of UE changes, base station side is only dispatched this UE by main carrier, issues data to this UE.Simultaneously, receive the uplink frame that this UE sends.In actual applications, can select any one in above-mentioned three kinds of default scheduling strategies to implement.

When this UE was the HSDPA subscriber equipment, sending module 601 specifically comprised HS-SCCH less operation mode activation instruction or HS-SCCH less operation pattern deexcitation instruction to the status command that this UE sends.When sending the instruction of HS-SCCH less operation mode activation to UE, be to be HS-SCCH less operation pattern with UE from original mode activation; When sending HS-SCCH less operation pattern deexcitation instruction to UE, be to be original pattern with UE from the deexcitation of HS-SCCH less operation pattern.Under HS-SCCH less operation pattern, UE both can be according to HS-SCCH less operation mode receive data when the state of UE, also can be according to original mode, i.e. and non-HS-SCCH less operation mode receive data.If but the state of UE under non-HS-SCCH less operation pattern, UE is according to non-HS-SCCH less operation mode receive data so.Therefore, the base station adopts HS-SCCH less operation mode or original mode can dispatch transmission for the UE that is under HS-SCCH less operation pattern; And for the UE that is under non-HS-SCCH less operation pattern, adopt original mode to dispatch transmission.

Correspondingly, scheduling strategy that should be default guarantees that the descending scheduling behavior is consistent with the HS-SCCH less operation pattern that this UE adopts, scheduler module 603 carry out for the concrete mode of the descending scheduling of this UE according to the scheduling strategy of presetting be: do not carry out the descending scheduling for this UE; Or, carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE; Or, carry out descending scheduling for this UE according to non-HS-SCCH less operation pattern.Particularly, do not carry out the descending scheduling for this UE, namely from sending status command to UE within the time interval of the HS-SCCH less operation mode state change of UE, base station side is no longer dispatched transmission processing to this UE.Simultaneously, receive the uplink frame that this UE sends.Carry out descending scheduling for this UE according to send original scheduling mode before status command to this UE, namely from sending status command to UE within the time interval of the HS-SCCH less operation mode state change of UE, base station side issues data according to original scheduling mode before sending status command to this UE to this UE.Simultaneously, receive the uplink frame that this UE sends.Carry out descending scheduling for this UE according to non-HS-SCCH less operation pattern, namely from sending status command to UE within the time interval of the HS-SCCH less operation mode state change of UE, base station side is dispatched this UE according to non-HS-SCCH less operation pattern (being original mode), issues data to this UE.Simultaneously, receive the uplink frame that this UE sends.In actual applications, can select any one in above-mentioned three kinds of default scheduling strategies to implement.

Particularly, judge module 602, concrete being used for judges according to the confirmation information that whether gets this UE whether the state of this UE changes, if do not get the feedback information of this UE or the feedback information that gets is not confirmation, judges that the state of this UE does not change.

Further, the state of UE does not change the two kinds of situations that comprise: the first situation is not get feedback information, in such cases, continues to obtain feedback information; The second situation is to have got feedback information but be not ACK, and in such cases, referring to Fig. 7, this equipment also comprises:

Retransmission module 604, the feedback information that is used for getting at judge module 602 is not ACK, after the state that judges this UE does not change, repeats sending module 601 and sends the step of status command to UE.

Further, referring to Fig. 8, this equipment also comprises:
