The speed of response, so as to improve the process performance of physical layer in the case where saving resource, reserved more processing times
To high-rise relevant scheduling or other processing.
As shown in Figure 1, the uplink receiving method of present embodiment, including：
Step 101：Parameter analysis of electrochemical subsystem shift to an earlier date N number of subframe to it is received by high level issue physical layer modulation message,
Cell-level relevant information and UE grades of relevant informations etc. carry out parameter calculating, determine channel and signal that may be present, and may
The physical layer process parameter of existing channel and signal；
UE grades of relevant informations are used for the parameter for determining which channel and signal and channel and signal.
The layer sequential distribution each with system of the value of N and function division are related, are usually 2.
Step 102：When definite PUSCH is channel that may be present, the processing of PUSCH and PUCCH multiplexings is carried out；
In a step 101 if according to the physical layer modulation message received, the UE is judged there are PUSCH, and have except SR
Outer control message needs to demodulate (whether there are PUCCH), then by the demodulation parameter (bag of the ascending control information of the UE
It is contained in physical layer parameter) it is multiplexed on PUSCH；If it is determined that the s UE are there are PUCCH, there is no PUSCH, then determining should
The control information of UE is in PUCCH channels.
As shown in Fig. 2, on the PUSCH of the demodulation parameter multiplexing of the above-mentioned ascending control information by UE, including：
Step 201：Judge whether the dispatch request (SR) of UE reaches the cycle, if reached, perform step 202；Otherwise,
Perform step 203；
Step 202：The relevant parameter of SR is added in the demodulation parameter of UCI (ascending control information)；
Step 203：Judge whether that the ACK/NACK for having been received by UE demodulates message, if received, perform step 204；
Otherwise, step 205 is performed；
Step 204：The ACK relevant parameters demodulated are added in the demodulation parameter of UCI；

Step 208：The demodulation parameter of UCI outside removing SR is passed to PUSCH processing subsystems；
Step 209：The demodulation parameter of UCI comprising SR is passed to PUSCH processing subsystems.
Step 103：When determining may be simultaneously present SRS and PUSCH, the preliminary inspection whether SRS conflicts with PCSCH is carried out
Survey, when determining may be simultaneously present SRS and PUCCH, carry out the Preliminary detection whether SRS conflicts with PUCCH；
As shown in figure 3, the Preliminary detection that SRS conflicts with PUSCH or progress SRS with PUCCH is carried out, including：
Step 301：Judge whether UE is in the cycle of SRS, if it is, performing step 302；Otherwise, it determines do not send out
Raw conflict；
It can learn whether UE is in the cycle of SRS according to the parameter of UE.
Step 302：Judge whether include the detection information of SR in UCI, if do not included, perform step 303；Otherwise,
Determine not clash；
Step 303：Judge whether to include the detection information of CQI in UCI, if included, perform step 304；Otherwise, really
It is fixed not clash；
Step 304：Abandon the processing information of SRS, it is believed that UE does not send SRS.
In UE there is no SR (when the reason for judging SR is that CQI conflicts with positive SR, it will abandon CQI), but there are CQI
When (ACK/NACK whether there is it is not intended that), it may appear that SRS conflicts with PUCCHFormat2/2a/2b's or PUSCH, UE meetings
Abandon SRS, the processing such as corresponding base station uplink receiving system also avoids the need for measuring the SRS of UE, otherwise carry out SRS's
Processing.
Step 104：After uplink receiver, which receives, eats dishes without rice or wine data, it is respectively started at each Channel Processing subsystem and signal
Subsystem is managed, makes to be in ready state, includes PUCCH processing subsystems, PUSCH processing subsystems and SRS processing subsystems, root
Channel task and/or signal task are sent at corresponding Channel Processing subsystem and/or signal according to the testing result of conflict
Reason subsystem is handled；
Each Channel Processing subsystem and signal processing subsystem are Concurrent Subsystem, and need not interact letter between each other
Breath.
Multiple subsystems can be completed by multiple CPU or Core or IP.
Same UE may be simultaneously present SRS and PUSCH, or there are SRS and PUCCH at the same time, i.e. may be same for a UE
When by SRS and PUSCH, or SRS and PUCCH are sent into two subsystems and handled, exist conflict when, it is preliminary by conflicting
After detection for a UE be in the case of more a moment only to SRS, PUSCH and PUCCH one of them at
Reason..
Step 105：Subsystems after treatment, comprehensive decision subsystem carry out comprehensive descision to demodulation result, really
The demodulation result reported is needed calmly, and reports demodulation result to high level.
As shown in figure 4, carrying out integrating judgement to demodulation result, determine to need the demodulation result reported, including：
Step 401：Judge that UE whether there is PUSCH, if it is present performing step 402；Otherwise, step 405 is performed；
Step 402：Judge that UE whether there is SRS, if it is present performing step 403；Otherwise, step 404 is performed；
Step 403：Determine to report the demodulation result of PUSCH and SRS, and reported；
Step 404：Determine to report the demodulation result of PUSCH, and reported；
Step 405：Judge that UE whether there is SRS, if it is present performing step 406；Otherwise, step 409 is performed；
Step 406：Judge that UE whether there is PUCCH, if it is present performing step 407；Otherwise, step 408 is performed；
Step 407：Determine to report the demodulation result of PUCCH and SRS, and reported；
Step 408：Determine to report the demodulation result of SRS, and reported；
Step 409：Judge that UE whether there is PUCCH, if it is present performing step 410；Otherwise, terminate, without appointing
What demodulation result reports；
Step 410：Determine to report the demodulation result of PUCCH, and reported.
PUCCH not only needs the detection for being conflicted and being multiplexed, the various control letter that PUCCH is included with PUSCH and SRS
Breath is equally also required to detection and the multiplexing process to conflict, specific processing is realized described below there is also conflict and multiplexing.
As shown in figure 5, the ACK/NACK of multiple ACK resources on PUCCH is demodulated, including：
Step 501：Signal-to-noise ratio (SNR) in potential ACK/NACK resources a to M (M >=1) existing for PUCCH inside or
Signal power measures, and obtains signal-to-noise ratio or the measured value of signal power；
Step 502：By obtained measured value and thresholding PCfgIt is compared, judges whether that measured value is more than thresholding PCfg
Resource, if it does not exist, then perform step 503；If it is present perform step 504；
Inside PUCCH there are the potential ACK/NACK resources of M in the case of, M is up to 4 (TDD multiplexings), at this time, elder generation
SNR in each ACK/NACK resources is measured, measured value PSNR, and by the measured value of signal-to-noise ratio and thresholding PCfgThan
Compared with.For the sake of simplicity, and based on the bottom of signal make an uproar difference it is little the fact, the measurement to SNR can be weakened as to signal power
Measurement, the measured value of signal power is PSignal, by the measured value P of signal powerSignalWith thresholding PCfgCompare.
Step 503：If PSignal, k＜ PCfg, (k=0,1...M-1), i.e., there is no measured value to be more than thresholding PCfgMoney
Source, then the testing result judgement in ACK/NACK resources is DTX (Discontinuous Transmission, discontinuous biography
It is defeated), i.e., UE does not send ACK/NACK；
Step 504：The resource of measured value maximum is selected, ACK/NACK solutions are carried out to the resource of the measured value maximum of selection
Adjust；
If Sum (Countif (PSignal, k＞ PCfg))=1, (k=0,1...M-1), the condition in Countif is true
When, the value of Countif is 1, is otherwise 0, i.e., there was only one in measurement result is higher than thresholding, then selected as measured value is higher than door
Limit PCfgResource carry out ACK/NACK demodulation；
If Sum (Countif (PSignal, k＞ PCfg)) ＞ 1, i.e., there are multiple measurement results be higher than thresholding resource, that
The demodulation of ACK/NACK is carried out to the highest resource of measured value.
Step 505：Processing is demodulated to other resources of PUCCH.
The detection carried out in present embodiment to ACK/NACK resources and demodulation process, can be no longer required for physical layer
Layer issues the exact demodulation resources of ACK, improves the efficiency of channel demodulation.
The optimization that can be realized to the method for ACK/NACK detection thresholds, is taken using the method based on average and variance
The gate method of generation reality, i.e., be more than a certain proportion of situation of average (this ratio usually relatively appearance in signal if there is variance
Easily choose), you can the corresponding resource of maximum variance is chosen to be demodulation object, if do not occurred, then it is assumed that be not reaching to thresholding
Resource, the demodulation result of ACK/NACK is regarded as DTX.
As shown in fig. 6, for CQI existing for PUCCH inside and Positive SR (positive dispatch request) in the case of conflicting
Detection, including：
Step 601：Judge whether UCI includes the detection information of SR, if including execution step 602；Otherwise, perform
Step 605；
Step 602：Whether detection SR sends, that is, it is Negative (negative) SR or PositiveSR to detect SR；
Step 603：Judge whether SR is Positive SR, if it is, performing step 604；Otherwise, step is performed
605；
Step 604：Determine that UE can abandon CQI, then the demodulation of CQI is also abandoned in base station, and records the mark for detecting SR；
Step 605：If SR is Negative SR, the demodulation module for starting CQI is handled in the resource of CQI.
As shown in fig. 7, the detection for SR in the case ofs conflicting with ACK existing for PUCCH inside, including：
Step 701：Judge whether UCI includes the detection information of SR, if including execution step 702；Otherwise, perform
Step 705；
Step 702：ACK/NACK is detected in the resource of SR；
Step 703：Judge whether testing result is DTX, if it is not, then performing step 704；Otherwise, step is performed
705；
Step 704：Record detects the mark of SR and the result of ACK/NACK；
Step 705：ACK/NACK is demodulated again in the resource of ACK/NACK.
There is a situation where that ACK/NACK conflicts with Positive SR for PUCCH inside, can first be carried out in the resource of SR
The demodulation of ACK/NACK, then determines the need for further re-starting in ACK/NACK resources further according to testing result
ACK/NACK is demodulated.If the ACK/NACK results detected in SR resources are DTX, i.e. signal power is not up to detection threshold,
It is considered that SR is Negative, ACK/NACK channels are demodulated again in the resource of ACK/NACK.
As shown in figure 8, (it is primarily referred to as high level to match somebody with somebody in the case of conflict with CQI for ACK/NACK existing for PUCCH inside
It is the situation that ACK/NACK and CQI cannot be passed altogether to put UE) detection, including：
Step 801：Judge that the high-rise CQI and ACK/NACK that whether configures can be passed altogether, if configuration can pass altogether, perform step
802；If configuration can not pass altogether, step 803 is performed；
Step 802：CQI and ACK/NACK is detected in CQI resources；
Step 803：ACK/NACK is detected in the resource of ACK/NACK；
Step 804：Judge whether testing result is DTX, if it is not, then performing step 805；Otherwise, step is performed
806；
Step 805：Record the result of ACK/NACK；
Step 806：CQI is detected in the resource of CQI.
ACK/NACK can be first individually detected with the situation about conflicting of CQI in ACK/NACK resources, be such as DTX, then
CQI resources are detected again, otherwise abandon the demodulation of CQI channels.In the case of high level configuration can be with simultaneous transmission, directly
The demodulation of CQI and ACK/NACK is carried out in CQI resources.
