Embodiment
Fig. 1 is the flow chart that the present invention realizes the method for CPC, as shown in Figure 1, comprising:
Step 100: the UE being in CPC pattern, reconfigures AP parameter according to CPC cycle parameter.
Before introducing CPC technology, because UE transmission data are continuous, as long as so the AP time division multiplexing cycle ensures that Resources allocation is reasonable, ensure that each UE takies equilibrium search time of base station, the length of integration and the length of non-integration can according to the performance of signal and load balancing configurations, ensure that the resource of base station search within this time is average, in the non-integrating time of a UE, the data of other UE of integration; And the application of CPC technology, make to reselect cycle of integration according to the cycle of CPC, ensure not have integrated noise when UE does not send signal by the integration when UE sends signal.So UE is once switch into CPC pattern, the length of Resourse Distribute and AP all will change according to CPC cycle parameter.
CPC pattern comprises CPC_Cycle1 pattern and CPC_Cycle2 pattern two kinds, and the UE being in CPC pattern is the UE being in CPC_Cycle1 pattern, or is in the UE of CPC_Cycle2 pattern.
When UE is in CPC pattern, (DTX) technology is launched owing to adopting downlink discontinuous, need the difference according to the configuration of CPC cycle parameter, AP parameter is reshuffled to the pattern in data burst (Burst) cycle adapting to new CPC pattern, thus guarantee that configuration AP searches within the Burst cycle of CPC.
An AP is cycle and the blanking cycle of Multipath searching data; The CPC cycle is that the CPC that agreement specifies sends the cycle of data and do not send the cycle of data.
Step 101: according to CPC cycle and AP situation, abandons the ADP packet that AP interior during non-Burst in the CPC cycle reports.
Those skilled in the art will know that, in CPC pattern, each task has Multipath searching task activity or pause period (AP, Active Pending) concept, at the non-integration (Distance) of AP in the cycle (namely in blanking cycle), task is not carried out integration and is not reported magnitude delay function (ADP, Amplitude Delay Profile) yet.The present invention utilizes the concept of AP, what achieve non-Burst period ADP data in the CPC cycle abandons operation, Fig. 2 is the principle schematic of the present invention to the process of ADP packet when being in CPC pattern, as shown in Figure 2, when being in CPC pattern and CPC_Cycle is greater than AP, now need to abandon the ADP packet that AP interior during non-Burst in the CPC cycle reports, as shown in the dotted box portion in Fig. 2, in Fig. 2, software AP and hardware AP is that expression can be realized by software or hardware, such as, by software, abandoning of ADP packet is judged, then operational order is handed down to abandoning of hardware implementing ADP packet.
In Multipath searching, namely there is coherence time and blanking time, every a few frame search multipath a period of time in the time division multiplexing in different relevant cycles, remaining time blanking, the inventive method utilizes blanking cycle to shield the cycle not sending signal in the CPC cycle, and search in the cycle sending signal, utilize the different AP time division multiplexing cycles to realize the process of CPC, achieve the process of the Multipath searching to CPC pattern.As in Fig. 2, there is signal the position of the corresponding Burst of the AP in integration period, in integration period; Do not have during signal and do not have integration data yet, the gap periods inside as AP in Fig. 2 there is not integration data, by the inventive method, has just in time fallen noise in this position full-shield.
Further, when UE switches between CPC pattern, the inventive method also comprises: according to CPC cycle stage before and after AP and switching, and process CPC reprovision also selects CPC to switch entry-into-force time point.
CPC has Three models: non-CPC pattern (CPC_NONE), CPC pattern 1 (CPC_Cycle1, also referred to as a CPC pattern), CPC pattern 2 (CPC_Cycle2, also referred to as the 2nd CPC pattern).When switching between CPC pattern, there is following restriction:
(1) UE does not directly enter CPC pattern from non-CPC pattern, and can only enter CPC pattern by reprovision wireless link;
(2) reprovision wireless link can not directly enter CPC_Cycle2 pattern, and only has first reprovision to enter CPC_Cycle1 pattern, then enters CPC_Cycle2 pattern by switching between CPC pattern;
(3) abandoning in order to ADP packet when processing switching, needs maintenance two intermediatenesses, i.e. CPC intermediateness 1 (CPC_MODE1_PENDING) and CPC intermediateness 2 (CPC_MODE2_PENDING).Wherein, CPC_MODE2_PENDING is the intermediateness being switched to CPC_Cycle2 pattern from CPC_Cycle1 pattern, and CPC_MODE1_PENDING is the intermediateness being switched to CPC_Cycle1 pattern from CPC_Cycle2 pattern;
(4) by the mode of reprovision wireless link, CPC_NONE can be turned back to from any state, comprise CPC_Cycle1 pattern and CPC_Cycle2 pattern and two intermediatenesses.
The schematic diagram that when Fig. 3 is wireless link of the present invention increase reprovision, the switching state of CPC pattern is safeguarded, as shown in Figure 3, under non-CPC pattern, UE is in CPC_NONE pattern, under CPC_NONE pattern, allow the reprovision wireless link message (Reconfig to CPC1) initiating to enter into CPC_Cycle1 pattern, in addition, also allow the increase chain circuit message (Reqadd/Reconfig RLs with CPC0) initiating to be switched to CPC_NONE pattern;
When UE is in CPC_Cycle1 pattern, the CPC initiating to be switched to CPC_Cycle2 is allowed to switch (Req swith to CPC2), or be switched to the reprovision wireless link message (Req Reconfig to CPC0) of CPC_NONE pattern, when UE enters CPC_Cycle2 pattern from the switching of CPC_Cycle1 pattern, first UE enters CPC_MODE2_PENDING state, after CPC switching message comes into force, more really proceed to CPC_Cycle2 pattern;
When UE is in CPC_Cycle2 pattern, the CPC initiating to be switched to CPC_Cycle1 pattern is allowed to switch (Req swith to CPC1), or be switched to the reprovision wireless link message (Req Reconfig to CPC0) of CPC_NONE pattern, when UE enters CPC_Cycle1 pattern from the switching of CPC_Cycle2 pattern, first UE enters CPC_MODE1_PENDING state, after CPC switching message comes into force, more really proceed to CPC_Cycle1 pattern.
Wherein, the intermediateness that CPC_MODE1_PENDING state and CPC_MODE2_PENDING state are safeguarded for software, during the state that mediates, the reprovision wireless link message (Req Reconfig to CPC0) being switched to CPC_NONE pattern can also be initiated.In Fig. 3, the pattern of three dash area displays is actual CPC pattern.Concerning hardware, CPC pattern is not known, and only need to start AP in the time of specifying according to the parameter of AP.
Under CPC pattern, need border behavior when accurately process CPC pattern switches, accurately select the switching entry-into-force time point of new CPC pattern, to avoid the search carrying out multipath during the non-Burst of CPC and the impact calculated systematic function.The new AP parameter of accurate configuration is with the appropriate ADP data abandoned during non-CPC Burst.CPC pattern is switched to the selection of entry-into-force time point, principle is the Burst head in the CPC cycle of new CPC pattern after finding nearest switching, using this Burst head as switching entry-into-force time point.Such as, in actual applications, determine that switching entry-into-force time point to come into force a same function used with determining AP undated parameter, when CPC pattern is switched, the parameter passing to this function is the length in new CPC cycle, and like this, what search out is exactly the nearest Burst head of target CPC pattern.
The correlation of CPC parameter and AP parameter comprises:
(1) the CPC cycle 2 (also referred to as the 2nd CPC cycle) during CPC_Cycle2 pattern is in, the multiple in the CPC cycle 1 (also referred to as a CPC cycle) during for being in CPC_Cycle1 pattern;
(2) permission AP is the multiple in CPC cycle 2, or common divisor; Require that AP is more than or equal to (>=) discontinuous transmission cycle 1 (DTX cycle1), and be the multiple of DTX Cycle1.
During the ADP data that the present invention reports during the switching processing CPC and CPC, follow following principle:
At the run duration of CPC_Cylce1 pattern and CPC_Cylce2 pattern, do not abandon any ADP data;
If AP is less than (<) the CPC cycle 2, then when configuring the AP parameter under CPC_Cycle2 pattern, extend AP interval to covering whole CPC_Cycle2 pattern;
When being switched to CPC_Cycle1 pattern from CPC_Cycle2 pattern, restart AP at the boundary point of CPC_Cycle1 pattern, this renewal may occur in the interim of an AP, instead of AP head;
Be switched to CPC_Cycle2 pattern from CPC_Cycle1 pattern, and when AP>=CPC the cycle 2, restart AP at the boundary point of CPC_Cycle2 pattern, this renewal may occur in the interim of an AP, instead of AP head;
Be switched to CPC_Cycle2 pattern from CPC_Cycle1 pattern, and when AP<CPC the cycle 2, between the Burst starting point of switching point to next CPC_Cycle2 pattern, if there is ADP packet to export, then abandon this ADP packet.
