Embodiments provide the method for submitting scheduling information of a kind of pair of carrier wave, by obtaining the state information of the data buffer storage of subscriber equipment, and obtain the UPH information of the first carrier of subscriber equipment and the UPH information of the second carrier wave respectively, and be reported to network side, improve the flexibility of two carrier wave reporting scheduling information.
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 the data buffer storage of subscriber equipment and the UPH information of this carrier wave, also only can report the UPH information of this carrier wave, can also be the state information of the data buffer storage of subscriber equipment and the UPH information of two carrier waves.
A complete schedule information (i.e. single carrier case dispatching information) is made up of following four parts:
Wherein, the computational methods of UPH are UPH=P
max, tx/ P
dPCCH, wherein P
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 determines RRC (Radio Resource Control, wireless heterogeneous networks) whole amount of available data of all logic channels of asking, show also simultaneously RLC (Radio Link Control, wireless spread-spectrum technology) transmission/retransmit time can data volume.
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 identify): when to there is many highest priority logical channel simultaneously, report buffer to take the highest channel.
It should be noted that, when triggering two carrier wave reporting scheduling informations in two carrier wave respectively, on the carrier wave being triggered reporting scheduling information, the state information of the data buffer storage of report of user equipment and the UPH information of this carrier wave.
Due to DPCCH (the Dedicated Physical Control Channel of UPH information and carrier wave, Dedicated Physical Control Channel) transmission code power relevant, when the two carrier wave of up employing, two differences that carrier wave is disturbed, therefore it is different that DPCCH used sends code power, and the UPH information reported is also just different.At MAC (Medium Access Control, medium education) in entity, such as: in MAC-e/MAC-i entity, two carrier waves share a buffer, TEBS, HLBS and HLID representative that two carrier waves report be same buffer situation, therefore carrying out two carrier wave SI gives the correct time, TEBS, HLBS and HLID can only report once, but UPH informational needs reports respectively, otherwise network side cannot calculate the power of maximum transmission E-DPCH on each carrier wave (E-DCH Dedicated Physical Channel, E-DCH DPCH).
The report method of the schedule information of two carrier waves that the embodiment of the present invention provides, be specially: reported on first carrier by the state information of the data buffer storage by subscriber equipment and the UPH information of first carrier, the UPH information of the state information of the data buffer storage of subscriber equipment and the second carrier wave is reported on a second carrier; Or the state information of the data buffer storage of report of user equipment and the UPH information of this carrier wave on a carrier wave in two carrier wave, another carrier wave only reports the UPH information of this carrier wave; Or 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 on first carrier or the second carrier wave.
See Fig. 2, it is the schematic flow sheet of the another embodiment of method for submitting scheduling information in the present invention.
In the present embodiment, when main explanation triggers first carrier and the second carrier wave reporting scheduling information in two carrier wave simultaneously, report in the MAC PDU that the UPH information (UPH1) of the data buffer storage information of the subscriber equipment in two carrier dispatching information and first carrier is sent at first carrier; The MAC PDU that the UPH information (UPH2) of the second carrier wave sends at the second carrier wave is reported.
Particularly, the while of two carrier waves during SI reporting, content-defined as follows:
Step 200, reports the SI information of complete 18bit at first carrier, comprise in this SI information: the UPH (5bit) of first carrier, TEBS (5bit), HLBS (4bit), HLID (4bit).
Step 201, changes to 5bit by the SI information of another carrier wave, only reports the UPH information of this carrier wave in this carrier wave; Particularly, only report UPH (5bit) information of this carrier wave at the second carrier wave, the state information (TEBS, HLBS, HLID) of the data buffer storage of subscriber equipment reports no longer on a second carrier.
Particularly, if when now having data to send on each carrier wave of described pair of carrier wave, the state information of a Stochastic choice 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 two carrier wave carrier wave has data to send, then select the carrier wave having data to send to report its UPH information, the carrier wave reported data buffer status information sent not having data 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 respective UPH information on two carrier waves.
It should be noted that, two carrier dispatching information reporting also can adopt the reporting schemes of all reported data buffer status information and UPH information thereof on two carrier waves all the time.
In the present embodiment, MAC-e/MAC-i PDU (Protocol Data Unit, protocol Data Unit) is filled to the situation of SI reporting, each carrier wave also independent reported data state cache information and respective UPH information of two carrier wave.Particularly, if the TBsize-24 that Datasize+Header <=E-TFCI selects, then add DDI (Data Description Indicator in MAC-eHeader part, data describe instruction) [111111], after MAC-e PDU, add state information and the UPH information of the data buffer storage of subscriber equipment; If the TBsize-18 that Datasize+Header <=E-TFCI selects, after MAC-e/MAC-i PDU, add state information and the UPH information of the data buffer storage of subscriber equipment.
The method for submitting scheduling information that the embodiment of the present invention provides, triggers two carrier wave reporting scheduling informations of two carrier wave simultaneously, the state information of reported data buffer memory and the UPH information of this carrier wave on a carrier wave; The UPH information of another carrier wave is only reported in another carrier wave, improve the efficiency of two carrier dispatching information reporting, and according to the two carrier dispatching information reported, can dispatch the resource of subscriber equipment on each carrier wave of two carrier wave, improve the flexibility of scheduling of resource.
See Fig. 3, it is the schematic flow sheet of the another embodiment of method for submitting scheduling information in the present invention.
The difference of the embodiment shown in the present embodiment and Fig. 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, as long as such network side receives from a carrier wave all schedule informations that schedule information just can obtain two carrier waves, network side can calculate the request rate of carrier wave according to the UPH of each carrier wave, can carry out the process of corresponding RG and AG scheduling authorization thus to each carrier wave.
In step 300, in the SI information of a complete 18bit, increase the UPH information that 5bit identifies another carrier wave, namely expand the schedule information reported on a carrier wave, form becomes:
Wherein that UPH1 representative is the UPH of the carrier wave of the SI information of carrying this expansion, and UPH2 represents another carrier wave UPH information.
If but the SG of two carrier waves all cannot the transmission of supporting business data (to the large small mode of fixing PDU, SG cannot send a RLC PDU, to the large small mode of variable PDU, SG cannot support that the data that E-TFCI is greater than 0 send), so because the transmission data that minimum E-TFCI is corresponding are 18bit, SI information now after expansion cannot be transmitted, therefore, for this situation, then report the SI information of two 18bit, the form of SI information (comprises the UPH of data buffer storage state information and this carrier wave with originally identical simultaneously.)。
Optionally, report a situation expanding SI information for two carrier waves, two carrier waves only can 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 to report the SI information of two carrier wave simultaneously; It should be noted that, the timing cycle of timer T_SIG and timer T_SING is configured by network side.
Two carrier waves are triggered for employing one group of timer carry out SI and report simultaneously, specifically describe as follows:
Situation 1 (Case 1):
Carrier wave 1:SG=" Zero_Grant " or all processes are all in unactivated state
Carrier wave 2:SG=" Zero_Grant " or all processes are all in unactivated state
If TEBS becomes the value being greater than 0, trigger and report two carrier wave SI information.
There are higher priority data to arrive in transmission buffer device, trigger two carrier wave SI reporting information.
Configure a SI shot timers information cycle T_SING, when carrier wave 1 and carrier wave 2 meet SG=" Zero_Grant " or all processes are all in unactivated state simultaneously, start to start timer T_SING.Timer T_SING timing instant then, triggers and reports two carrier wave SI information.After triggering reports two carrier wave SI information, timer T_SING restarts.During timing, if enter the state of situation 2 (Case2) or situation 3 (Case3) due to certain carrier wave SG or process status change, and stop T_SING timer, start timer T_SIG simultaneously.Have SI to trigger during timing to give the correct time and will restart 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
If TEBS > 0 and the SG of certain carrier wave become a too little PDU that can not transmit arbitrary MAC-d and flow, or the current SG of two carrier waves is too little when can not transmit the PDU that arbitrary MAC-d flows, TEBS becomes the value being greater than 0, triggers and reports two carrier wave SI information.
If a certain carrier wave E-DCH Serving cell changes, and new Serving cell does not belong to original service E-DCH RLS, triggers and reports two carrier wave SI information.
When at least one carrier wave meets SG < > " Zero_Grant " and when having at least a process to be all in state of activation, start to start timer T_SIG.Timer T_SIG timing instant then, triggers the SI information reporting two carrier waves.After triggering the SI information reporting two carrier wave, timer T_SIG restarts.During timing, if enter the state of Case1 due to two carrier wave SG or process status change, trigger SI, and stop T_SIG timer, restart timer T_SING simultaneously, if now TEBS > 0, trigger SI reporting; If enter the state of situation 3 (Case3), T_SIG restarts.If trigger SI reporting information during timing, restart timer T_SIG.
Situation 3 (Case 3):
Carrier wave 1:SG=" Zero_Grant " or all processes be all in unactivated state
Carrier wave 2:SG < > " Zero_Grant " and have at least a process to be in state of activation
If TEBS > 0 and the SG of carrier wave 2 become too little when can not transmit that a PDU that arbitrary MAC-d flows or the current SG of carrier wave 2 is too little can not transmit the PDU that arbitrary MAC-d flows TEBS become the value being greater than 0, trigger the SI information reporting two carrier waves;
If the E-DCH Serving cell of carrier wave 2 changes, and new Serving cell does not belong to original service E-DCH RLS, triggers the SI information reporting two carrier waves.
When at least one carrier wave meets SG < > " Zero_Grant " and when having at least a process to be in state of activation, start to start timer T-SIG.Timer T_SIG timing instant then, triggers the SI information reporting two carrier waves.After triggering the SI information reporting two carrier wave, timer T_SIG restarts.During timing, if enter Case1 state due to carrier wave SG or process status change, stop T_SIG timer, restart timer T_SING simultaneously, if now TEBS > 0, trigger the SI information reporting two carrier waves; If enter Case2 state, timer T_SIG restarts.During timing, when triggering the SI information reporting two carrier wave, restart timer T_SIG.
It should be noted that, in Case3, a carrier wave SG=" Zero_Grant " or all processes be all 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 trigger element 5001 also can trigger two carrier wave reporting scheduling information simultaneously, or difference reporting scheduling information, such as, when HARQ transmission failure, also causes triggering the SI information reporting two carrier waves, particularly:
If the SI information that two carrier waves report respectively, the cycle of waiting timer triggers, and reports the SI information of 18bit respectively.
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 to the situation of SI reporting, also to revise accordingly: if the TBsize-29 that Datasize+Header <=E-TFCI selects, then add DDI [111111] in MAC-e Header part, after MAC-e PDU, add the SI information of the expansion of 23bit; If the TBsize-23 that Datasize+Header <=E-TFCI selects, after MAC-e/MAC-i PDU, add the SI information of the expansion of 23bit.
No matter be that event triggers or the cycle triggers, if two carrier waves all do not have transfer of data, then on two carrier waves, report the UPH of buffer status information and corresponding carriers respectively; Only have when a carrier wave has data to send, the carrier wave having transfer of data reports the SI information (UPH1, UPH2, TEBS, HLBS, HLID) of expansion; If two carrier waves have data to send, so can send the SI information (UPH1, UPH2, TEBS, HLBS, HLID) expanded by Stochastic choice carrier wave, fill redundant bit minimum principle when also can select according to E-TFCI and select a carrier wave to send the SI information (UPH1, UPH2, TEBS, HLBS, HLID) of expansion.
It should be noted that, when employing independently reports the reporting schemes of UPH information of buffer status information and corresponding carriers all the time on two carrier waves, also can use the one group of timer provided in the embodiment of the present invention.When timer period triggers or event triggers reporting scheduling information, report full schedule information (UPH1, TEBS, HLBS, HLID) at first carrier, report full schedule information (UPH2, TEBS, HLBS, HLID) on a second carrier.
Optionally, in the present embodiment, trigger when reporting two carrier dispatching information, UPH1, UPH2, TEBS, HLBS, HLID can be reported at first carrier, report UPH2, UPH1, TEBS, HLBS, HLID on a second carrier simultaneously.Namely on two carrier waves, all report the schedule information of expansion simultaneously
