Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Inventor is found by research, 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) received, no matter be deinterleaving, demodulation, descrambling still separates chnnel coding, not by the interference of these other results of user terminal, there is good independence.Following examples utilize this independence, determine to carry out parallel processing to the RI information deinterleaving parsing of multiple reverse link traffic channel control informations of multiple user terminal, CQI information length, then, again CQI deinterleaving parsing, CQI information and the parallel processing of RI information combination are carried out to the multiple control informations determining CQI information length, thus decrease the stand-by period of system process, reduce the complexity of scheduling.
With reference to Fig. 2, show the flow chart of steps of a kind of reverse link traffic channel control information analytic method according to the embodiment of the present invention one, comprise the following steps:
Step S202: obtain the rank of matrix instruction RI information of each control information in multiple reverse link traffic channel control information and store;
This step is the first obtaining step, the control information that base station receiving terminal sends, a terminal once sends a control information to base station, base station is processing the control information of the multiple user terminals received sometime, first the control information process carried out is RI deinterleaving and parsing, by RI deinterleaving and parsing, obtain RI information.
In this step, RI deinterleaving and parsing are carried out to the control information of user uplink Traffic Channel in base station simultaneously, instead of wait for that the reverse link traffic channel control information of a user determines its CQI information length according to RI information, then after carrying out CQI deinterleaving parsing, carry out RI deinterleaving and the parsing of the control information of next user uplink Traffic Channel again.Such as, the reverse link traffic channel control information of first user is being carried out to RI deinterleaving and namely starting to carry out RI deinterleaving and parsing to second subscriber control information after resolving, meanwhile, another handling procedure RI information after resolving according to first subscriber control information that then starts determine this control information CQI information length, carry out CQI deinterleaving, the like, the program that process RI deinterleaving is resolved and the program parallelization determining CQI information length perform, and multiple subscriber control information is carried out to RI deinterleaving and parsing, determines CQI information length.
That is, while this step of execution, parallel execution of steps S204.
Step S204: use RI information to determine the CQI information length of each control information;
This step is determining step, base station while RI deinterleaving and parsing are carried out in the control information other not being carried out to RI deinterleaving and parsing, to the control information having carried out RI deinterleaving and parsing, according to RI information determination CQI information length.Such as, the CQI information length of second or the 3rd control information, while carrying out RI deinterleaving and parsing to the 3rd or the 4th control information, is determined in base station.
Step S206: CQI deinterleaving and CQI dissection process are carried out to the control information determining CQI information length, obtains the CQI information of this control information;
This step is the second obtaining step, and RI deinterleaving and parsing have been carried out to all in base station, and CQI deinterleaving and parsing are carried out in the control information that CQI information length is determined.Such as, RI deinterleaving and parsing are all being carried out to four control informations in base station, and after determining the CQI information length of four control informations, start to carry out CQI deinterleaving and parsing to first control information, afterwards CQI deinterleaving and parsing are carried out to second control information, meanwhile, RI information and CQI information combination are carried out to the control information having carried out CQI deinterleaving and parsing, this step at one time in section can with step S208 executed in parallel.
Or base station is after having carried out RI deinterleaving and parsing to all control informations, the program only having CQI information length to determine is run, now in order to reduce processing delay, can carry out starting CQI deinterleaving and parsing while CQI information length is determined.Such as, RI deinterleaving and parsing are all being carried out to four control informations in base station, and determine the CQI information length of first three control information, now, the CQI information length of the 4th control information is still had not determine, then can, while the CQI information length determining the 4th control information, start to carry out CQI deinterleaving and parsing to first control information.After the CQI information length of four control informations is all determined, the CQI deinterleaving of executed in parallel control information is resolved and RI information and CQI information combine.
Step S208: the RI information of the CQI information of the control information of acquisition and this control information of storage is reconfigured.
This step is combination step, and such as, the combination of the information of CQI information and RI, while carrying out CQI deinterleaving and parsing to second control information, is carried out in base station to first control information, this step and step S206 can executed in parallel.The above-mentioned of the present embodiment carries out the process of control information United Dispatching parsing as shown in Figure 3 to the control information that multiple user terminal UE sends.In Fig. 3 after UE0 completes RI deinterleaving and parsing, in each time period in one or more time periods that the RI deinterleaving of process UE1 to UEn is resolved, the program parallelization all simultaneously having CQI information length to judge performs.Unlike, after all UE are completed RI deinterleaving parsing, the CQI information length of at least one UE is still had to judge not complete, can namely start at this moment to carry out CQI deinterleaving resolving, also after the CQI information length of all UE can be waited to have judged, then start to carry out CQI deinterleaving parsing (the CQI information length of this all UE has judged that rear mode of just carrying out CQI deinterleaving parsing can increase the time delay of process a little).Then, the CQI deinterleaving of UE is resolved and RI information and CQI information combine 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 correlation technique, press user scheduling to multiple control information to resolve, after current RI deinterleaving completes, namely stop process, enter loitering phase, until after obtaining the RI analytic value of the current UE reported, the CQI information length just starting to carry out current UE judges and CQI deinterleaving and parsing, thus control information process time delay is long, and the time of system wait is also long, and Scheduling Design complexity is high.Pass through the present embodiment, to RI deinterleaving parsing and the parallel disposed of in its entirety of CQI information length judgement of multiple control information, to CQI deinterleaving resolve and RI information and CQI information combination carry out parallel disposed of in its entirety, reach the performance that enhancing system carries out control information parsing, reduce control information and resolve time delay, promote the effect of the performance of whole process.Meanwhile, when carrying out parallel disposed of in its entirety, constantly need not carry out Parameter Switch when processing conversion, thus reducing system call complexity.
