Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The inventor is through discovering; In the process that receiving terminal is resolved the RI information in the reverse link traffic channel control information (comprising RI information and CQI information) that receives; No matter be deinterleaving, demodulation, descrambling is still separated chnnel coding; Do not receive the interference of these other results of user terminal, have independence preferably.Following examples are utilized this independence; RI information deinterleaving to a plurality of reverse link traffic channel control informations of a plurality of user terminals is resolved, the CQI message length confirms to carry out parallel processing; Then; Again CQI deinterleaving parsing, CQI information and the parallel processing of RI information combination are carried out in a plurality of control informations of having confirmed the CQI message length, thereby reduced the stand-by period of system handles, reduced the complexity of scheduling.
With reference to Fig. 2, show flow chart of steps according to a kind of reverse link traffic channel control information analytic method of the embodiment of the invention one, may further comprise the steps:
Step S202: the rank of matrix indication RI information and the storage of obtaining each control information in a plurality of reverse link traffic channel control informations;
This step is first obtaining step; The control information that the base station receiving terminal sends; A control information is once sent to the base station in terminal, and is handling the control information of a plurality of user terminals of receiving sometime the base station, and it is RI deinterleaving and parsing that the control information of at first carrying out is handled; Through RI deinterleaving and parsing, obtain RI information.
In this step; The base station simultaneously to the user uplink Traffic Channel control information carry out RI deinterleaving and parsing; Rather than the reverse link traffic channel control information of waiting for a user confirms its CQI message length according to RI information, carries out carrying out after the CQI deinterleaving is resolved the RI deinterleaving and the parsing of the control information of next user uplink Traffic Channel more again.For example; After first user's reverse link traffic channel control information being carried out the RI deinterleaving and being resolved, promptly begin second subscriber control information carried out RI deinterleaving and parsing; Meanwhile; RI information after another handling procedure then begins to resolve according to first subscriber control information confirm this control information the CQI message length, carry out the CQI deinterleaving; And the like, handle the program of RI deinterleaving parsing and the program parallelization of definite CQI message length and carry out, a plurality of subscriber control informations are carried out RI deinterleaving and parsing, confirm the CQI message length.
That is, when carrying out this step, executed in parallel step S204.
Step S204: use RI information to confirm the CQI message length of each control information;
This step is for confirming step, and the CQI message length to having carried out the control information of RI deinterleaving and parsing, is confirmed according to RI information in the base station when RI deinterleaving and parsing are carried out in the control information of other not being carried out RI deinterleaving and parsing.For example, the CQI message length of second or the 3rd control information is confirmed in the base station when RI deinterleaving and parsing are carried out in the 3rd or the 4th control information.
Step S206: CQI deinterleaving and CQI dissection process are carried out in the control information of having confirmed the CQI message length, obtain the CQI information of this control information;
This step is second obtaining step, and RI deinterleaving and parsing have been carried out to all in the base station, and CQI deinterleaving and parsing are carried out in the control information that the CQI message length is confirmed.For example; RI deinterleaving and parsing are all being carried out to four control informations in the base station, and after having confirmed the CQI message length of four control informations, begin CQI deinterleaving and parsing are carried out in first control information; Afterwards CQI deinterleaving and parsing are carried out in second control information; Simultaneously, RI information and CQI information combination are carried out in the control information of having carried out CQI deinterleaving and parsing, this step at one time the section in can with step S208 executed in parallel.
Perhaps, the base station is after having carried out the RI deinterleaving and having resolved to all control informations, and the program running that only has the CQI message length to confirm in order to reduce processing delay, can carry out starting CQI deinterleaving and parsing when the CQI message length is confirmed at this moment.For example; RI deinterleaving and parsing are all being carried out to four control informations in the base station; And confirmed the CQI message length of first three control information, at this moment, still had the CQI message length of the 4th control information not confirm; Then can in the CQI message length of confirming the 4th control information, begin CQI deinterleaving and parsing are carried out in first control information.After the CQI of four control informations message length was all confirmed, the CQI deinterleaving of executed in parallel control information was resolved and RI information and CQI information combination.
Step S208: the RI information of this control information of the CQI information of the control information of obtaining and storage is reconfigured.
This step is a combination step, and for example, the combination of the information of CQI information and RI is carried out to first control information in the base station when CQI deinterleaving and parsing are carried out in second control information, and this step and step S206 can executed in parallel.The process that the parsing of control information uniform dispatching is carried out in the above-mentioned control information to a plurality of user terminal UE transmissions of present embodiment is as shown in Figure 3.After UE0 had accomplished the RI deinterleaving and resolved, in each time period in one or more time periods that the RI deinterleaving of handling UE1 to UEn is resolved, the program parallelization that all has the CQI message length to judge was simultaneously carried out among Fig. 3.Different is; After all UE have accomplished RI deinterleaving parsing; Still there is the CQI message length of at least one UE to judge completion; Can promptly begin to carry out CQI deinterleaving resolving at this moment, also can wait the CQI message length of all UE judge to accomplish after, begin to carry out the CQI deinterleaving again and resolve (the CQI message length of this all UE judge just carry out the time delay that mode that the CQI deinterleaving resolves can increase processing a little after accomplishing).Then, the CQI deinterleaving of UE is resolved and RI information and CQI information combination executed in parallel.
To sum up, in the present embodiment, step S202 and step S204 executed in parallel, step S206 and step S208 executed in parallel.
In the correlation technique, a plurality of control informations are dispatched parsing by the user, after current RI deinterleaving is accomplished; Promptly stop to handle, get into loitering phase, after the RI of the current UE that obtains reporting analytic value; Just begin to carry out the judgement of CQI message length and the CQI deinterleaving and the parsing of current UE; Thereby control information processing time-delay is long, and the time of system wait is also long, and the scheduling design complexity is high.Pass through present embodiment; The RI deinterleaving of a plurality of control informations is resolved and the parallel disposed of in its entirety of CQI message length judgement; The CQI deinterleaving is resolved and RI information and the CQI information combination disposed of in its entirety that walks abreast; Reach enhanced system and carried out the performance that control information is resolved, reduced control information and resolve time delay, promoted the effect of the performance of entire process.Simultaneously, when walking abreast disposed of in its entirety, need not constantly when treatment conversion, carry out the parameter conversion, thereby reduce the system call complexity.
With reference to Fig. 4, show schematic flow sheet according to a kind of reverse link traffic channel control information analytic method of the embodiment of the invention two.Present embodiment all sends a control information to the base station with each UE among three UE; Totally three control informations; It is example that these three control informations are handled on base station parallel ground; This parallel processing process is divided into seven time periods, and setting the control information of three UE processing sequence successively is UE1, UE2, UE3.
The control information analytic method of present embodiment may further comprise the steps:
Step S402: in the very first time section, RI deinterleaving and parsing are carried out to the control information of UE1 in the base station, obtain RI information and the storage of UE1;
In first time period, earlier one in a plurality of control informations (being the control information of UE1) carried out RI deinterleaving and parsing, to obtain the RI information of this control information, the ID of this RI information and UE1 is stored together.
Step S404: in second time period, RI deinterleaving and parsing are carried out to the control information of UE2 in the base station, obtain RI information and the storage of UE2, simultaneously the CQI message length are carried out in the control information of UE1 and confirm;
In this step, in second time period, RI deinterleaving and parsing are carried out in the control information to UE2 in the base station, in the time of storage RI information and ID, according to the RI information that obtains among the step S402 CQI message length are carried out in the control information of UE1 and confirm.
Step S406: in the 3rd time period, RI deinterleaving and parsing are carried out to the control information of UE3 in the base station, obtain RI information and the storage of UE3, simultaneously the CQI message length are carried out in the control information of UE2 and confirm;
Step S408: in the 4th time period, the base station is carried out the CQI message length to the control information of UE3 and is confirmed, simultaneously, begins CQI deinterleaving and parsing are carried out in the control information of UE1;
Through this step, the RI deinterleaving of UE1, UE2 and UE3 is resolved and the CQI message length is confirmed all to accomplish.Simultaneously; In order to reduce time delay; Carry out when the CQI message length confirms in the control information of having only UE3, CQI deinterleaving and parsing are carried out in the control information that starts UE1, make the two executed in parallel; Making so also has two processing procedures carrying out together in the 4th time period, thereby has further reduced the control information processing delay.
Step S410: in the 5th time period, CQI deinterleaving and parsing are carried out to the control information of UE2 in the base station, simultaneously CQI information and RI information combination are carried out in the control information of UE1;
In this step, resolving the CQI of UE1, after the CQI information of acquisition UE1; During according to parsing CQI, the ID of CQI control information corresponding is the ID of UE1, obtains the information storage addresses of UE1; With the RI information and the CQI information combination of information storage addresses, perhaps, CQI information is connected to the RI information of this address storage after; Become the control information after the parsing, the control information dissection process of UE1 is accomplished.
Step S412: in the 6th time period, CQI deinterleaving and parsing are carried out to the control information of UE3 in the base station, simultaneously, CQI information and RI information combination are carried out in the control information of UE2;
Through this step, the control information of UE2 is resolved and is accomplished.
Step S414: in the 7th time period, CQI information and RI information combination are carried out to the control information of UE3 in the base station.
Through this step, the control information of three UE is resolved all and is accomplished.
With reference to Fig. 5, show flow chart of steps according to a kind of reverse link traffic channel control information analytic method of the embodiment of the invention three.In the present embodiment, two control informations of sending with two UE are example.Make a start at UE, first user UE1 accounts for a Resource Block, and 10 RI data, 15 ack msgs, 24 CQI data and 110 DATA data are arranged; Second user UE2 accounts for a Resource Block, and 12 RI data, 8 ack msgs, 30 CQI data and 102 DATA data are arranged, and be as shown in Figure 6.

Step S508: scheduler module is judged the CQI raw information length of respective user according to the RI analysis result of UE1, and the length of calculating after this user CQI encodes is 24; Scheduler module issues the RI data length of UE2 simultaneously, and de-interleaving block takes out 12 RI data of this user, accomplishes deinterleaving, and the result to deinterleaving carries out the demodulation scramble process then.
Step S510: the result of the RI demodulates information descrambling of UE2 is sent into the RI parsing module, and the RI that accomplishes this user resolves, and the result of parsing divides two-way, offers scheduler module on the way, and one the tunnel deposits among the RAM together with control information packet header according to user totem information.
Step S512: scheduler module is judged the CQI raw information length of respective user according to the RI analysis result of UE2, and the length of calculating after this user CQI encodes is 30; Scheduler module is handed down to de-interleaving block with ACK information and the CQI message length of UE1 simultaneously, successively takes out 15 ack msgs, 24 CQI data.
Step S514: with ack msg that obtains after the UE1 deinterleaving and CQI data, carry out the demodulation descrambling, and give corresponding parsing module, accomplish the parsing of ACK information and CQI information with result.
Step S516: when the ACK of UE1 information and the completion of CQI information analysis, from RAM, read this user's RI analytic value, organize word again, be written in the control information bag with CQI information that obtains and CQI message length information.
Being 32 with the system bus bit wide is example, and concrete packing process is: after CQI resolves end, be index with the ID; Obtain the corresponding information storage addresses of this ID, the RI information that deposits in before taking out from this address is then with RI information and CQI information; And the length of CQI information puts together, forms the bus data of 32 bit wides, the control information after obtaining resolving; Thereby reduce the length of control information bag, save the required RAM resource that takies, alleviate the pressure of system bus.
Step S518: scheduler module is handed down to de-interleaving block with ACK information and the CQI message length of UE2, successively takes out 8 ack msgs, 30 CQI data.
Step S520: with ack msg that obtains UE2 after the deinterleaving and CQI data, carry out the demodulation descrambling, and give corresponding parsing module, accomplish the parsing of ACK information and CQI information with result.
Step S522: when the ACK of UE2 information and the completion of CQI information analysis, from RAM, read this user's RI analytic value, organize word again, be written in the control information bag with CQI information that obtains and CQI message length information.
Step S524: after two users' control information bag packing finished, disposable control information with two users reported high layer software.
