Embodiment
The invention process provides a kind of method for submitting scheduling information, Apparatus and system, for the reporting of scheduling information (SI) mode of two carrier waves provides solution, can dispatch the resource of subscriber equipment on each carrier wave of two carrier waves, improves the flexibility of scheduling of resource.
Below in conjunction with accompanying drawing, the detailed description embodiment of the invention provides in each embodiment method for submitting scheduling information, Apparatus and system.
Referring to Fig. 1, be the schematic flow sheet of method for submitting scheduling information embodiment among the present invention.
The method of present embodiment comprises:
Alternatively, MAC PDU (the Medium AccessControl Protocol Date Unit that the subscriber equipment power headroom of the subscriber equipment power headroom of the state information of described data buffer storage and described first carrier and the second carrier wave is sent at carrier wave, media access control protocol data unit) sends to physical layer in, send to again NodeB (Node Base, base-station node).
The embodiment of the invention provides the method for submitting scheduling information of a kind of pair of carrier wave, the state information of the data buffer storage by obtaining subscriber equipment, and obtain respectively the UPH information of first carrier of subscriber equipment and the UPH information of the second carrier wave, and it is reported to network side, improved the flexibility of two carrier wave reporting scheduling informations.
Schedule information refers to state information, the UPH information of the data buffer storage of subscriber equipment.In embodiments of the present invention, the schedule information that each carrier wave reports, can be the state information of data buffer storage of subscriber equipment and the UPH information of this carrier wave, also can only report the UPH information of this carrier wave, can also be the state information of data buffer storage of subscriber equipment and the UPH information of two carrier waves.
A complete schedule information (being single carrier case dispatching information) is comprised of following four parts:
Wherein, the computational methods of UPH are UPH=P
Max, tx/ P
DPCCH, P wherein
Max, tx=min{Maximumallowed UL TX Power, P
Max, P
MaxIt is the normalized peak power output of UE.P
DPCCHThe power of DPCCH code.
The state information of the data buffer storage of subscriber equipment comprises:
TEBS (Total E-DCH Buffer Status, the buffer status that E-DCH is total): TEBS has determined RRC (Radio Resource Control, Radio Resource control) whole amount of available data of all logic channels of request, also represented simultaneously the data volume that RLC (Radio Link Control, Radio Link control) transmits/can use when retransmitting.
HLBS (Highest priority Logical channel Buffer Status, highest priority logical channel buffer status), HLBS represents that highest priority logical channel takies the situation of buffer.
HLID (Highest priority Logical channel ID, highest priority logical channel sign): when having many highest priority logical channel simultaneously, report buffer to take the highest channel.
Need to prove, when two carrier wave reporting scheduling informations that trigger respectively in pair carrier waves, on the carrier wave of reporting scheduling information that is triggered, the UPH information of the state information of the data buffer storage of report of user equipment and this carrier wave.
Because DPCCH (the Dedicated Physical Control Channel of UPH information and carrier wave, Dedicated Physical Control Channel) transmission code power is relevant, when the two carrier wave of up employing, two differences that carrier wave is disturbed, therefore it is different that used DPCCH sends code power, and the UPH information that reports is also just different.At MAC (Medium Access Control, the media access control) in the entity, for example: in the MAC-e/MAC-i entity, two carrier waves share a buffer, two TEBS that carrier wave reports, what HLBS and HLID represented is same buffer situation, therefore give the correct time carrying out two carrier wave SI, TEBS, HLBS and HLID can only report once, but the UPH informational needs reports respectively, otherwise network side can't calculate the power of the maximum E-DPCH of transmission (E-DCH Dedicated Physical Channel, E-DCH DPCH) on each carrier wave.
The report method of the schedule information of two carrier waves that the embodiment of the invention provides, be specially: by the state information of the data buffer storage of subscriber equipment and the UPH information of first carrier are reported at first carrier, the state information of the data buffer storage of subscriber equipment and the UPH information of the second carrier wave are reported at the second carrier wave; The perhaps UPH information of the state information of the data buffer storage of report of user equipment and this carrier wave on carrier wave in two carrier waves only reports the UPH information of this carrier wave on another carrier wave; Perhaps the state information of the data buffer storage of subscriber equipment and the UPH information of first carrier and the UPH information of the second carrier wave are all reported at first carrier or the second carrier wave.
Referring to Fig. 2, be the schematic flow sheet of the another embodiment of method for submitting scheduling information among the present invention.
In the present embodiment, when main explanation triggers in two carrier waves first carrier and the second carrier wave reporting scheduling information simultaneously, the data buffer storage information of the subscriber equipment in two carrier dispatching information and the UPH information (UPH1) of first carrier are reported in the MAC PDU that first carrier sends; The UPH information (UPH2) of the second carrier wave is reported at the MAC PDU that the second carrier wave sends.
Particularly, two carrier waves are simultaneously during SI reporting, and are content-defined as follows:
Particularly, if when on each carrier wave of described pair of carrier wave, having this moment data to send, select at random the state information of a carrier wave reported data buffer memory and the UPH information of this carrier wave, only report the UPH information of this carrier wave at another carrier wave; Only have when having data to send on the carrier wave of two carrier waves, the carrier wave of then selecting to have data to send reports its UPH information, in the carrier wave reported data buffer status information that does not have data to send and its UPH information.Certainly, when triggering at the same time, if when two carrier waves all do not have data to send, all reported data buffer status information and UPH information separately on two carrier waves.
Need to prove that two carrier dispatching information reportings also can adopt all the time on two carrier waves the mode that reports of reported data buffer status information all and UPH information thereof.
In the present embodiment, for the situation of MAC-e/MAC-i PDU (Protocol Data Unit, protocol Data Unit) filling SI reporting, each carrier wave of two carrier waves is independent reported data state cache information and UPH information separately also.Particularly, if the TBsize-24 that Datasize+Header＜=E-TFCI selects, then partly add DDI (Data Description Indicator at MAC-eHeader, the data description indication) [111111], state information and the UPH information of adding the data buffer storage of subscriber equipment in MAC-e PDU back; If the TBsize-18 that Datasize+Header＜=E-TFCI selects, state information and the UPH information of adding the data buffer storage of subscriber equipment in MAC-e/MAC-i PDU back.
The method for submitting scheduling information that the embodiment of the invention provides triggers two carrier wave reporting scheduling informations of two carrier waves, the UPH information of the state information of reported data buffer memory and this carrier wave on a carrier wave simultaneously; In another carrier wave, only report the UPH information of another carrier wave, improved the efficient of two carrier dispatching information reportings, and according to the two carrier dispatching information that report, can on each carrier wave of two carrier waves, dispatch the resource of subscriber equipment, improve the flexibility of scheduling of resource.
Referring to Fig. 3, be the schematic flow sheet of the another embodiment of method for submitting scheduling information among the present invention.
The difference of present embodiment and embodiment shown in Figure 2 is, the UPH information of the state information of the data buffer storage of subscriber equipment and two carrier waves reports at a carrier wave, network side is as long as receive that from a carrier wave schedule information just can obtain all schedule informations of two carrier waves like this, network side can carry out corresponding RG and the processing of AG scheduling authorization to each carrier wave thus according to the request rate that the UPH of each carrier wave can calculate carrier wave.
In step 300, in the SI of complete 18bit information, increase the UPH information that 5bit identifies another carrier wave, namely expand the schedule information that reports at a carrier wave, form becomes:
Wherein that UPH1 representative is the UPH of carrier wave that carries the SI information of this expansion, and UPH2 represents another carrier wave UPH information.
If but the transmission that the SG of two carrier waves can't the supporting business data is (to the fixing large small mode of PDU, SG can't send a RLC PDU, to the large small mode of variable PDU, SG can't support E-TFCI to send greater than 0 data), so because minimum transmission data corresponding to E-TFCI are 18bit, SI information after expansion this moment can't be transmitted, therefore, for this situation, then report simultaneously the SI information of two 18bit, the form of SI information and the original identical (UPH that comprises data buffer storage state information and this carrier wave.)。
Optionally, report a situation of expanding SI information for two carrier waves, two carrier waves can only use one group of timer T_SIG and T_SING, that is:
In step 301, adopt one group of timer T_SIG and T_SING to trigger simultaneously to report the SI information of two carrier waves; Need to prove that the timing cycle of timer T_SIG and timer T_SING is disposed by network side.
Carry out SI and report for adopting one group of timer to trigger simultaneously two carrier waves, specifically describe as follows:
Situation 1 (Case 1):
Carrier wave 1:SG=" Zero_Grant " or all processes all are in unactivated state
Carrier wave 2:SG=" Zero_Grant " or all processes all are in unactivated state
If TEBS becomes the value greater than 0, trigger two carrier wave SI information that report.
There are the higher priority data to arrive in the transmission buffer device, trigger two carrier wave SI reporting information.
Dispose a SI and trigger timer T_SING information cycle, when carrier wave 1 and carrier wave 2 satisfy simultaneously SG=" Zero_Grant " or all processes and all be in unactivated state, begin to start timer T_SING.Timer T_SING regularly then triggers two carrier wave SI information that report constantly.Timer T_SING restarted after triggering reported two carrier wave SI information.During timing, if enter the state of situation 2 (Case2) or situation 3 (Case3) owing to certain carrier wave SG or process status change, and stop the T_SING timer, start simultaneously timer T_SIG.There is SI to trigger to give the correct time regularly and will restarts timer T_SING.
Situation 2 (Case 2):
Carrier wave 1:SG＜＞" Zero_Grant " and have at least a process to be in state of activation
Carrier wave 2:SG＜＞" Zero_Grant " and have at least a process to be in state of activation
The too little PDU that can not transmit arbitrary MAC-d stream if the SG of TEBS＞0 and certain carrier wave becomes, or the current SG of two carrier waves is during a too little PDU that can not transmit arbitrary MAC-d stream, TEBS becomes the value greater than 0, triggers two carrier wave SI information that report.
If a certain carrier wave E-DCH Serving cell changes, and new Serving cell do not belong to original service E-DCH RLS, triggers two carrier wave SI information that report.
When at least one carrier wave satisfy SG＜＞" Zero_Grant " and when having at least a process all to be in state of activation, begin to start timer T_SIG.Timer T_SIG regularly then triggers the SI information that reports two carrier waves constantly.After triggering reported the SI information of two carrier waves, timer T_SIG restarted.During timing, if owing to two carrier wave SG or process status change the state that enters Case1, trigger SI, and stop the T_SIG timer, restart simultaneously timer T_SING, if this moment TEBS＞0, trigger SI reporting; If enter the state of situation 3 (Case3), T_SIG restarts.If trigger SI reporting information regularly, restart timer T_SIG.
Situation 3 (Case 3):
Carrier wave 1:SG=" Zero_Grant " or all processes all be in unactivated state
Carrier wave 2:SG＜＞" Zero_Grant " and have at least a process to be in state of activation
TEBS becomes value greater than 0 during the too little PDU that can not transmit arbitrary MAC-d stream of too little PDU that can not transmit arbitrary MAC-d stream or carrier wave 2 current SG if the SG of TEBS＞0 and carrier wave 2 becomes, and triggers the SI information that reports two carrier waves;
If the E-DCH Serving cell of carrier wave 2 changes, and new Serving cell do not belong to original service E-DCH RLS, triggers the SI information that reports two carrier waves.
When at least one carrier wave satisfy SG＜＞" Zero_Grant " and when having at least a process to be in state of activation, begin to start timer T-SIG.Timer T_SIG regularly then triggers the SI information that reports two carrier waves constantly.After triggering reported the SI information of two carrier waves, timer T_SIG restarted.During timing, if enter the Case1 state owing to carrier wave SG or process status change, stop the T_SIG timer, restart simultaneously timer T_SING, if this moment TEBS＞0, trigger the SI information that reports two carrier waves; If enter the Case2 state, timer T_SIG restarts.Regularly, when triggering the SI information that reports two carrier waves, restart timer T_SIG.
Need to prove, in Case3, a carrier wave SG=" Zero_Grant " or all processes all be in unactivated state, and another carrier wave SG＜＞" Zero_Grant " and have at least a process to be in state of activation, also can use timer T_SING.
Certainly, Event triggered unit 5001 also can trigger simultaneously reporting scheduling information of two carrier waves, perhaps distinguishes reporting scheduling information, for example when the HARQ bust this, also causes triggering the SI information that reports two carrier waves, particularly:
If two SI information that carrier wave reports respectively, the cycle of waiting timer triggers, and reports respectively the SI information of 18bit.
Otherwise two carrier waves report the SI information of a 23bit.
Because the schedule information of expansion is 23bit, so MAC-e/MAC-i PDU is filled the situation of SI reporting, also to revise accordingly: if the TBsize-29 that Datasize+Header＜=E-TFCI selects, then partly add DDI[111111 at MAC-e Header], the SI information of adding the expansion of 23bit in MAC-e PDU back; If the TBsize-23 that Datasize+Header＜=E-TFCI selects, the SI information of adding the expansion of 23bit in MAC-e/MAC-i PDU back.
No matter be to trigger in Event triggered or cycle, if all do not have transfer of data on two carrier waves, then report respectively the UPH of buffer status information and corresponding carriers at two carrier waves; Only have when having data to send on the carrier wave, report the SI information (UPH1, UPH2, TEBS, HLBS, HLID) of expansion at the carrier wave that transfer of data is arranged; If there are data to send on two carrier waves, can select at random so a carrier wave to send the SI information (UPH1, UPH2, TEBS, HLBS, HLID) of expansion, fill the principle of redundant bit minimum in the time of also can selecting according to E-TFCI and select a carrier wave to send the SI information (UPH1, UPH2, TEBS, HLBS, HLID) of expansion.
Need to prove, adopt the UPH information on two carrier waves, independently report all the time buffer status information and corresponding carriers report mode the time, the one group of timer that provides in the embodiment of the invention also can be provided.When the triggering of timer cycle or Event triggered reporting scheduling information, report full schedule information (UPH1, TEBS, HLBS, HLID) at first carrier, report full schedule information (UPH2, TEBS, HLBS, HLID) at the second carrier wave.
Optionally, in the present embodiment, trigger when reporting two carrier dispatching information, can report UPH1, UPH2, TEBS, HLBS, HLID at first carrier, report UPH2, UPH1, TEBS, HLBS, HLID at the second carrier wave simultaneously.Namely on two carrier waves, all report simultaneously the schedule information of expansion

Timer cycle trigger element 5000 comprises at least one group of timer, be specially timer (T_SIG) and timer (T_SING), the timing cycle of T_SIG and T_SING is used for triggering first carrier and the second carrier wave while reporting scheduling information of two carrier waves by the network side configuration.
Certainly, two carrier waves also can adopt two groups of timers to trigger respectively each carrier wave, when two groups of timers when two carrier waves of same time trigger carry out SI reporting information, also can think simultaneously two carrier wave SI reporting information that trigger.
When first carrier and the second carrier wave were distinguished reporting scheduling information in two carrier waves, first carrier and the second carrier wave disposed respectively one group of timer, and these two groups of timers work alone, and are independent of each other.
Carry out SI and report for adopting one group of timer to trigger simultaneously two carrier waves, specifically describe as follows:
Situation 1 (Case 1):
Carrier wave 1:SG=" Zero_Grant " or all processes all are in unactivated state
Carrier wave 2:SG=" Zero_Grant " or all processes all are in unactivated state
If TEBS becomes the value greater than 0, trigger two carrier wave SI information that report.
There are the higher priority data to arrive in the transmission buffer device, trigger two carrier wave SI reporting information.
Dispose a SI and trigger timer T_SING information cycle, when carrier wave 1 and carrier wave 2 satisfy simultaneously SG=" Zero_Grant " or all processes and all be in unactivated state, begin to start timer T_SING5001.Timer then triggers two carrier wave SI information that report.Timer restarted after triggering reported two carrier wave SI information.During timing, if enter the state of situation 2 (Case2) or situation 3 (Case3) owing to certain carrier wave SG or process status change, and stop the T_SING timer, start simultaneously timer T_SIG.There is SI to trigger to give the correct time regularly and will restarts timer.
Situation 2 (Case 2)
Carrier wave 1:SG＜＞" Zero_Grant " and have at least a process to be in state of activation
Carrier wave 2:SG＜＞" Zero_Grant " and have at least a process to be in state of activation
The too little PDU that can not transmit arbitrary MAC-d stream if the SG of TEBS＞0 and certain carrier wave becomes, or the current SG of two carrier waves is during a too little PDU that can not transmit arbitrary MAC-d stream, TEBS becomes the value greater than 0, triggers two carrier wave SI information that report.
If a certain carrier wave E-DCH Serving cell changes, and new Serving cell do not belong to original service E-DCH RLS, triggers two carrier wave SI information that report.
When at least one carrier wave satisfy SG＜＞" Zero_Grant " and when having at least a process all to be in state of activation, begin to start timer.Timer then triggers the SI information that reports two carrier waves.After triggering reported the SI information of two carrier waves, timer restarted.During timing, if owing to two carrier wave SG or process status change the state that enters Case1, trigger SI, and stop the T_SIG timer, restart simultaneously timer T_SING, if this moment TEBS＞0, trigger SI reporting; If enter the state of situation 3 (Case3), T_SIG restarts.If trigger SI reporting information regularly, restart timer.
Situation 3 (Case 3)
Carrier wave 1:SG=" Zero_Grant " or all processes all be in unactivated state
Carrier wave 2:SG＜＞" Zero_Grant " and have at least a process to be in state of activation
TEBS becomes value greater than 0 during the too little PDU that can not transmit arbitrary MAC-d stream of too little PDU that can not transmit arbitrary MAC-d stream or carrier wave 2 current SG if the SG of TEBS＞0 and carrier wave 2 becomes, and triggers the SI information that reports two carrier waves;
If the E-DCH Serving cell of carrier wave 2 changes, and new Serving cell do not belong to original service E-DCH RLS, triggers the SI information that reports two carrier waves.
When at least one carrier wave satisfy SG＜＞" Zero_Grant " and when having at least a process to be in state of activation, begin to start timer T_SIG.Timer then triggers the SI information that reports two carrier waves.After triggering reported the SI information of two carrier waves, timer restarted.During timing, if enter the Case1 state owing to carrier wave SG or process status change, stop the T_SIG timer, restart simultaneously timer T_SING5001, if this moment TEBS＞0, trigger the SI information that reports two carrier waves; If enter the Case2 state, timer T_SIG restarts.Regularly, when triggering the SI information that reports two carrier waves, restart timer.
Need to prove, in case3, a carrier wave SG=" Zero_Grant " or all processes all be in unactivated state, and another carrier wave SG＜＞" Zero_Grant " and have at least a process to be in state of activation, also can use timer T_SING.
Certainly, Event triggered unit 5001 also can trigger simultaneously reporting scheduling information of two carrier waves, perhaps distinguishes reporting scheduling information, for example, when the HARQ bust this, also causes triggering the SI information that reports two carrier waves, particularly:
If two SI information that carrier wave reports respectively, the cycle of waiting timer triggers, and reports respectively the SI information of 18bit.
Otherwise two carrier waves report the SI information of a 23bit.
