The embodiment of the present invention relates to the physical layer of LTE system, and the module related to mainly contains: RF (radio-frequency module), MC (physical layer main control software module), UL_RAPC (uplink random access control module), CSR_GAPC (Cell searching different-frequency measure module) and TPU (clock control module).Wherein:
RF is used for receiving and sending signal of eating dishes without rice or wine.In LTE system, up-downgoing shares a RF module;

TPU provides clock reference for each hardware module, for each software module provides precise time timing.
As shown in Figure 2, one embodiment of the invention proposes a kind of method coordinated LTE system Stochastic accessing and conflict with different-frequency measure, comprising:
Step S101, MC receive and forward the high-rise random access request sent to UL_RAPC, receive and forward the high-rise different-frequency measure request sent to CSR_GAPC;
Wherein, the relevant parameter configuration information from high level is carried in random access request and different-frequency measure request, the random access request from high level received together is forwarded to UL_RAPC together with relevant parameter configuration information, by the different-frequency measure request forward from high level to CSR_GAPC by MC.
Step S102, UL_RAPC are according to random access request, CSR_GAPC according to different-frequency measure request, and in conjunction with different-frequency measure mark, the fiducial time provided with TPU, control RF carries out work respectively.
Wherein, different-frequency measure mark comprises is safeguarded by MC, is used for marking that the first different-frequency measure of current high level configuration different-frequency measure state identifies, and is safeguarded by UL_RAPC, is used for marking the second different-frequency measure that current random access procedure seizes different-frequency measure state and identifies.When the first different-frequency measure is designated true time, show that current high level is configured to preferentially carry out different-frequency measure; When the second different-frequency measure is designated true time, show that random access procedure does not seize different-frequency measure, preferentially carry out different-frequency measure.In the present embodiment, the initial condition of two different-frequency measure marks is set to: the initial condition of the first different-frequency measure mark is false; The initial condition of the second different-frequency measure mark is true.
When random access request and different-frequency measure request are forwarded to UL_RAPC and CSR_GAPC by MC respectively, MC arranges the first different-frequency measure simultaneously and is designated very.
The present embodiment forwards high level requests information by MC and arranges different-frequency measure initial condition, and UL_RAPC is by inquiry first different-frequency measure mark and safeguard the second different-frequency measure mark, and the fiducial time provided by TPU, control RF carries out Stochastic accessing work; CSR_GAPC is by inquiry second different-frequency measure mark, and the fiducial time provided by TPU, control RF carries out different-frequency measure work.
When conflicting on Stochastic accessing and different-frequency measure not life period, UL_RAPC and CSR_GAPC concurrent working.Until the different-frequency measure from high level configuration receiving MC forwarding stops or Stochastic accessing exits request and quits work respectively.
When Stochastic accessing and conflicting in different-frequency measure life period, UL_RAPC and CSR_GAPC according to predetermined priority with respective mode of operation.
As shown in Figure 3, in step S102, UL_RAPC is according to random access request, and in conjunction with different-frequency measure mark, the fiducial time provided with TPU, the step that control RF carries out work comprises:
Step S1021, UL_RAPC select random access guiding resource according to random access request, determine to send random access guiding subframe time;
Step S1022, is designated true time when inquiring the first different-frequency measure, obtains the different-frequency measure time;
Step S1023, the next and different-frequency measure time not afoul transmission random access guiding subframe time according to current system Stochastic accessing state confirmation;
Step S1024, registration TPU time-event, control RF sends leading at the random access guiding subframe time selected, and the second different-frequency measure mark is set to vacation;
Step S1025, after Stochastic accessing is sent completely, is set to true by the second different-frequency measure mark.
Current system Stochastic accessing state comprises non-competing Stochastic accessing state and/or competition Stochastic accessing state.
Particularly, the working method of UL_RAPC is as follows:
1, UL_RAPC receives the random access request that MC forwards, and line parameter of going forward side by side configures;
2, carry out random access procedure resource selection, determine to send random access guiding subframe time;
3, inquiring different-frequency measure mark A is true time, calculates the concrete subframe time of different-frequency measure;
4, confirm next leading transmission subframe, make its time not with different-frequency measure time conflict;
According to the different conditions of current system Stochastic accessing, there are following three kinds of situations:
1) during non-competing Stochastic accessing, present frame eNB selectes leader resource and conflicts with different-frequency measure, avoids present frame and sends, send random access guiding in next frame same asset;
2) when TDD system standard (PRACH Mask Index is equal to zero) competes Stochastic accessing, the subframe scope of not conflicting with different-frequency measure is selected to carry out resource selection, if all subframe all exists conflict, then the next available sub-frame not in different-frequency measure time range is selected to carry out random access guiding resource selection;
3) during the competition Stochastic accessing of other situations, when selected random access guiding send resource conflict with different-frequency measure time, in the next available sub-frame or not in different-frequency measure time range, use same parameter to carry out resource selection.
5, register TPU time-event, front 2 subframes (be less than CSR_GAPC operation RF and the need the time) time being predefined in transmission random access guiding wakes Stochastic accessing module up;
6, the time alarm that UL_RAPC receives TPU module is activated work, first check whether the first different-frequency measure mark is true: if be true, whether the random access guiding that then query count has been selected sends resource and conflicts with different-frequency measure, if there is conflict, then turns back to resource selection step 4;
7, determine that random access guiding transmission does not exist with different-frequency measure to conflict, calculate random access guiding and send required parameter, line correlation of going forward side by side is arranged, and sends leading in allocated resource;
8, the second different-frequency measure mark is set to vacation, carries out the leading step afterwards of random access procedure;
9, after this time Stochastic accessing is sent completely (comprising access success or access failure), the second different-frequency measure mark is set to true.
As shown in Figure 4, in step S102, CSR_GAPC is according to different-frequency measure request, and in conjunction with different-frequency measure mark, the fiducial time provided with TPU, the step that control RF carries out work comprises:
Step S1026, CSR_GAPC are according to the different-frequency measure request determination different-frequency measure time;
Step S1027, when CSR_GAPC inquires the first different-frequency measure mark and the second different-frequency measure mark is true time, according to different-frequency measure time registration TPU time-event, control RF carries out different-frequency measure work.
Particularly, the working method of CSR_GAPC is as follows:
1, CSR_GAPC receives the different-frequency measure request that MC forwards;
2, inquire about first, second different-frequency measure mark, if both are true, according to different-frequency measure time started registration TPU time-event, carry out different-frequency measure cycling for control RF;
3, TPU time-event wakes CSR_GAPC up, and control RF carries out different-frequency measure work;
4, different-frequency measure result reports MC, until the different-frequency measure work receiving MC forwarding stops request.
According to LTE protocol regulation, need to avoid different-frequency measure when sending random access guiding, and after leading end before sending, the priority of random access procedure is higher than different-frequency measure.Because uplink random access belongs to different modules from different-frequency measure, can not use radio frequency resource each other, once there is work conflict, then need by using different-frequency measure mark mark current operating state, order carries out work simultaneously.Stochastic accessing belongs to process complexity in addition, and simultaneously sudden do not have periodic physical process more by force, so Stochastic accessing is as major maintenance different-frequency measure identification module, and different-frequency measure only needs to carry out work according to the second different-frequency measure mark.
As shown in Figure 5, below for a Stochastic accessing and different-frequency measure conflict process, above-described embodiment is described.For simplicity, FDD system is supposed, when system-frame 0, high level configures random access request when subframe 0, and subframe 1 configures different-frequency measure request, and the subframe 0 and 6 of network side configuration is simultaneously random access guiding available resources, different-frequency measure, from 4 subframes, lasts till the 9th subframe, cycle 40ms.Set the first different-frequency measure simultaneously and be designated different-frequency measure mark A, the second different-frequency measure is designated different-frequency measure mark B, and concrete Conflict solving step is as follows:
1, System Frame Number 0, the 0th subframe, MC forwards random access request and configures to UL_RAPC module;
2, System Frame Number 0, the 0th subframe, UL_RAPC receives request, and carries out resource selection, after checking different-frequency measure mark A, does not find conflict, is selected in subframe 6 sends random access guiding according to network configuration parameters, and register TPU time-event and wake up in the 4th subframe;
3, System Frame Number 0, the 1st subframe, MC receives high-rise configuration different-frequency measure request and is forwarded to CSR_GAPC module, and it is true for configuring different-frequency measure mark A simultaneously, and arranges subframe 4 for the different-frequency measure time started;
4, System Frame Number 0, the 1st subframe, CSR_GAPC judges that different-frequency measure mark A and B is very, and registration TPU time-event wakes up in the 2nd subframe;
5, System Frame Number 0, the 2nd subframe, TPU wakes CSR_GAPC module up, CSR_GAPC block configuration different-frequency measure parameter, obtains RF control (switching radio frequency 2 subframe time consuming time), and starts to carry out different-frequency measure in the 4th subframe, continue 6 subframe time;
6, System Frame Number 0,4th subframe, CSR_GAPC starts to carry out different-frequency measure on the one hand, TPU time-event wakes UL_RAPC module up on the other hand, and RAPC module checks that different-frequency measure mark A is true, and calculating different-frequency measure sends with random access guiding and conflicts, re-start resource selection, avoid within the scope of different-frequency measure, select next frame the 0th sub-frame resources to send leading, and register TPU time-event and wake UL_RAPC module up when the 8th subframe;
7, System Frame Number 0, the 8th subframe, TPU time-event wakes UL_RAPC module up.It is true that UL_RAPC detects different-frequency measure mark A, after calculating and finding that different-frequency measure and random access guiding send and do not conflict, calculates leading parameter and is configured, preparing to send random access guiding after 2 subframes, different-frequency measure being identified B simultaneously and be set to very;
8, System Frame Number 0, at the end of the 9th subframe, the 6ms time of different-frequency measure ends, and measurement result is reported protocol stack, check different-frequency measure mark A be very after, registration TPU time-event wakes CSR_GAPC module up in System Frame Number 4 the 2nd subframe;
9, System Frame Number 1, the 0th subframe, Stochastic accessing send leading, and when Stochastic accessing does not complete afterwards pro-jobs level higher than different-frequency measure;
10, System Frame Number 4,2nd subframe TPU time-event wakes CSR_GAPC module up, CSR_GAPC checks that different-frequency measure mark A is true, continues to check different-frequency measure mark B, if be also true, then calculate relevant parameter and arrange, control radio-frequency module and proceed different-frequency measure in the 4th subframe, if contrary different-frequency measure is designated vacation, show current Stochastic accessing still for priority higher stage, this time different-frequency measure work is not done, and registers TPU time-event and wake up in System Frame Number 8 the 2nd subframe;
11, Stochastic accessing completes, and different-frequency measure is identified B and is set to very, and conflict does not exist.
As can be seen from above-mentioned example:
1), random access guiding needs to calculate GAP position, when guaranteeing to send leading not within the scope of different-frequency measure 2 times;
2), random access guiding finds different-frequency measure provisional configuration conflicting with leading transmission before sending, and need according to GAP position, use parameter current re-starts resource selection;
3), CSR_GAPC checks that mark A and B is when being true, and just can carry out work;
4), after MC receives high-rise configuration Stochastic accessing or different-frequency measure exit message, conflict does not exist, and two modules work separately.
It should be noted that at this, when simultaneously PRACH MASK INDEX is 0 to TDD system standard, UL_RAPC receive random access request first resource selection time, need in selected subframe and carry out Stochastic choice within the scope of continuous 2 subframes afterwards to send resource.Now, UL_RAPC is by calculating, if find that 3 continuous subframes exist the available sub-frame resource not within the scope of different-frequency measure, just within the scope of this, carry out resource selection, simultaneously can according to Stochastic choice resource location, separately in selected subframe (before) or last subframe, one is selected to send resource as subsequent use, after UL_RAPC is waken up by TPU event, find that first time is selected and different-frequency measure work conflict, directly can check whether selection for subsequent use also conflicts, send density to strengthen random access guiding, raise the efficiency.
