Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of dispatching method.
Background technology
In order to guarantee that TD SDMA inserts (TD-SCDMA) system and Long Term Evolution plan-time division multiplexing (LTE-TDD) system coexists in same geographic area, that is: guarantee that TD-SCDMA system and LTE-TDD system the situation that time slot intersects do not occur in the same moment, need carry out the scheduling of ascending time slot and descending time slot according to certain strategy in TD-SCDMA system and LTE-TDD system.The time slot intersection is meant: synchronization, the time slot type in TD-SCDMA system and LTE-TDD system is different.For example: suppose to be engraved in the TD-SCDMA system when a certain and be scheduled as ascending time slot, and in the LTE-TDD system, be scheduled as descending time slot, the time slot intersection then occurred.
In actual applications, TD-SCDMA system and the LTE-TDD system that is in the same geographic area may be with being operated in a frequency range, such as 2300MHz～2400MHz frequency range; Also may be operated in different frequency range respectively, at 2010MHz～2025MHz frequency range or 1880MHz～1920MHz, and the LTE-TDD system works is in 2300MHz～2400MHz frequency range such as the TD-SCDMA system works.The present situation that respectively TD-SCDMA system under the both of these case and LTE-TDD system is coexisted in same geographic area is introduced below.
Because under the situation of TD-SCDMA system and LTE-TDD system same frequency section, when planning LTE-TDD, alignd to the boundary of time slot of TD-SCDMA system in subframe border in the LTE-TDD system, therefore, prior art has proposed strategy as shown in Figure 1 and has solved TD-SCDMA system and the LTE-TDD system time slot cross-cutting issue in same geographic area with frequency range.Referring to Fig. 1:
DwPTS represents descending pilot frequency time slot, and UpPTS represents uplink pilot time slot, and DL TS represents descending time slot, and UL TS represents ascending time slot.TS0～TS6 shown in Fig. 1 the 1st row is the time slot 0～time slot 6 in the subframe of TD-SCDMA system.Subframe 0～subframe 4 shown in Fig. 1 the 2nd～6 row is 5 subframes in the field of LTE-TDD system, and wherein, subframe 1 is fixed for transmitting pilot signal.The length of a subframe equals the length of a field in the LTE-TDD system in the TD-SCDMA system, is 5ms.
According to Fig. 1 the 1st row and the 2nd row, for needs and UL: DL is 5: 1, and TS1～TS5 is scheduling to the LTE-TDD system that ascending time slot, TS6 are scheduling to the TD-SCDMA coexistence of systems of descending time slot, can adopt UL: DL=3: 1 proportioning is carried out timeslot scheduling, and the end of subframe 4 is alignd with the end of TS5, subframe 2～subframe 4 is scheduling to ascending time slot, subframe 0 is scheduling to descending time slot.Described UL: DL represents the ratio of ascending time slot number and descending time slot number.
According to Fig. 1 the 1st row and the 3rd row, for needs and UL: DL is 4: 2, and TS1～TS4 is scheduling to the LTE-TDD system that ascending time slot, TS5 and TS6 are scheduling to the TD-SCDMA coexistence of systems of descending time slot, can adopt UL: DL=2: 2 proportioning is carried out timeslot scheduling, and the end of subframe 3 is alignd with the end of TS4, subframe 2 and subframe 3 are scheduling to ascending time slot, subframe 0 and subframe 4 are scheduling to descending time slot.
According to Fig. 1 the 1st row and the 4th row, for needs and UL: DL is 3: 3, and TS1～TS3 is scheduling to the LTE-TDD system that ascending time slot, TS4～TS6 are scheduling to the TD-SCDMA coexistence of systems of descending time slot, can adopt UL: DL=2: 2 proportioning is carried out timeslot scheduling, and the end of subframe 3 is alignd with the end of TS3, subframe 2 and subframe 3 are scheduling to ascending time slot, subframe 0 and subframe 4 are scheduling to descending time slot.
According to Fig. 1 the 1st row and the 5th row, for needs and UL: DL is 2: 4, and TS1 and TS2 are scheduling to the LTE-TDD system that ascending time slot, TS3～TS6 are scheduling to the TD-SCDMA coexistence of systems of descending time slot, can adopt UL: DL=1: 3 proportioning is carried out timeslot scheduling, and the end of subframe 2 is alignd with the end of TS2, subframe 2 is scheduling to ascending time slot, subframe 0, subframe 3 and subframe 4 are scheduling to descending time slot.
According to Fig. 1 the 1st row and the 6th row, for needs and UL: DL is 1: 5, and TS1 is scheduling to the LTE-TDD system that ascending time slot, TS2～TS6 are scheduling to the TD-SCDMA coexistence of systems of descending time slot, can adopt UL: DL=0: 4 proportioning is carried out timeslot scheduling, and the end of subframe 1 is alignd with the end of TS1, subframe 0, subframe 2～subframe 4 all are scheduling to descending time slot.
Under the situation of TD-SCDMA system and LTE-TDD coexistence of systems, the dual-mode terminals of supporting two nets of TD-SCDMA system and LTE-TDD system to switch need be measured the received power (RSRP) of reference channel of LTE-TDD and the quality of reception (RSRQ) of reference channel under the TD-SCDMA pattern, that is: the 1st and the 2nd common pilot symbols of DwPTS that need measurement LTE-TDD system.
The present inventor finds: according to Fig. 1, under the proportioning strategy shown in the 2nd, 3,5,6 row, the time of occurrence of the 1st～2 common pilot symbols of the DwPTS of LTE-TDD system corresponds to the TS0 in the TD-SCDMA system.Because TS0 is usually as time slot, base station (Node B) will periodically issue broadcast message in the TS0 of each field, therefore, when needs are measured the DwPTS of LTE-TDD system, dual-mode terminal can temporarily not receive the data of TS0, and utilize the DwPTS of this time measurement LTE-TDD system, this processing mode can't impact the regular traffic of this dual-mode terminal.
Yet under the proportioning strategy that the TD-SCDMA system employing 3: 3 shown in Fig. 1 the 4th row, LTE-TDD system adopt 2: 2, the time of occurrence of the 1st～2 common pilot symbols of the DwPTS of LTE-TDD system corresponds to the TS6 in the TD-SCDMA system.TS6 is the descending time slot in the TD-SCDMA system, and dual-mode terminal need receive the business datum that Node B issues at TS6, therefore, and can't be in the measurement of TS6 realization to the LTE-TDD system.And can't realize measurement to the LTE-TDD system also just can't realize TD-SCDMA system and LTE-TDD system in same geographic area, coexist under dual-mode terminal switch to the LTE-TDD system.
Under the situation of TD-SCDMA system and LTE-TDD system different frequency range, subframe border in the LTE-TDD system does not require to the alignment of the boundary of time slot of TD-SCDMA system, and prior art does not propose feasible technical scheme as yet and is used to realize measurement to the LTE-TDD system.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Main thought of the present invention is by being provided for carrying out the measuring period of LTE-TDD systematic survey, and when dispatching, for each dual-mode terminal that need carry out the LTE-TDD systematic survey kept one period that is not scheduled in each measuring period, thereby, dual-mode terminal can carry out the LTE-TDD systematic survey in the time that it is not scheduled, and then realizes that TD-SCDMA system and LTE-TDD system coexist in same geographic area.
Fig. 2 is the schematic flow sheet of dispatching method of the present invention.Method shown in Figure 2 is used under the condition that TD-SCDMA system and LTE-TDD system coexist in same geographic area, realizes the measurement of dual-mode terminal to the LTE-TDD system, and referring to Fig. 2, this method comprises:
Step 201: the measuring period that is provided for carrying out the LTE-TDD systematic survey.
In this step, the purpose that be set described measuring period is periodically the LTE-TDD system to be measured.When specific implementation, the Node B in the TD-SCDMA system can determine whether newly supposed the base station of LTE-TDD system around it according to the network configuration cases in the practical application, and be set described measuring period in view of the above.
Below with described measuring period correspondence the number of frame be expressed as N.Preferably, N should be more than or equal to 2.
Step 202: the dual-mode terminal of determining to carry out the LTE-TDD systematic survey.
According to prior art, Node B can determine the common geographic range that covers in this area under one's jurisdiction and LTE-TDD system usually, thereby can determine to carry out the geographic range of LTE-TDD systematic survey.
In this step, Node B can determine the position that each dual-mode terminal is current according to the Bo Dajiao (DOA) of each received dual-mode terminal, and judge whether described position is within the geographic range that described needs carry out the LTE-TDD systematic survey, need carry out within the geographic range of LTE-TDD systematic survey if the position of certain dual-mode terminal is in, then this dual-mode terminal is defined as carrying out the dual-mode terminal of LTE-TDD systematic survey.
Step 203: when dispatching, for each dual-mode terminal that need carry out the LTE-TDD systematic survey kept one period that is not scheduled in each measuring period.
By this step, can guarantee that each dual-mode terminal has one period that is not scheduled in each measuring period.Utilize this time that is not scheduled, dual-mode terminal can carry out the measurement of LTE-TDD system.
When the operation of the described retention time of specific implementation, whether be operated in same frequency range according to TD-SCDMA system and LTE-TDD system, the present invention provides diverse ways respectively.
First kind of situation: as previously mentioned, when TD-SCMDA system and LTE-TDD system works with frequency range the time, only under following scene, can't realize in the bimodulus measurement to the LTE-TDD system:
The timeslot scheduling strategy of TD-SCMDA system is: the time slot 1～time slot 3 in each frame is scheduling to ascending time slot, time slot 4～time slot 6 is scheduling to descending time slot;
The timeslot scheduling strategy of LTE-TDD system is: subframe 2 and subframe 3 in each field are scheduling to ascending time slot, and subframe 0 and subframe 4 are scheduling to descending time slot;
In the described LTE-TDD system in the end of the subframe 3 of each field and the described TD-SCMDA system end of the time slot 3 of each frame align.
At this scene, this step can be when dispatching, for each dual-mode terminal that need carry out the LTE-TDD systematic survey keeps a time slot that is not scheduled 6 in each measuring period, make dual-mode terminal in its time slot that is not scheduled 6, to carry out the LTE-TDD systematic survey.
And for the data that originally need in this time slot that is not scheduled 6, pass to dual-mode terminal down, can be dispatched to and transmit in time slot 4 in this frame or the time slot 5, also can be dispatched in the next frame and transmit.This may cause that the time slot 4 of this frame and time slot 5 loads are big slightly, but can not influence the normal transmission of data.
When specific implementation, can adopt mode at random to determine which dual-mode terminal is not scheduled on the time slot 6 of present frame.For example: suppose 30 dual-mode terminals of current existence, set measuring period, the number of frame of correspondence was 5, no matter taked which kind of selection mode, as long as make described 30 dual-mode terminals have the chance that once is not scheduled on the time slot 6 in per 5 frames.For the load of balanced each time slot, can in each frame, select 6 dual-mode terminals at random, the time slot 6 of this frame is not dispatched to described 6 dual-mode terminals.
Preferably, can also adopt following method provided by the invention to carry out the selection of dual-mode terminal:
At first, distribute different integer M for different dual-mode terminals; Wherein, 0＜=M＜N;
Then, for each dual-mode terminal, when the eligible SFN mod of frame number SFN N=M, the time slot in this frame 6 is not dispatched to described dual-mode terminal.
It is easy to adopt above-mentioned preferred approach not only to realize, and can guarantee the load of time slot 6 and the load balance of other time slots.If different usefulness adopts identical M per family, time slot 4 will occur and time slot 5 loads are too big, and time slot 6 loads very gently or at all there is not the situation of load.
Second kind of situation: when TD-SCMDA system and LTE-TDD system works during at different frequency range, in this step, can be when dispatching, for each dual-mode terminal that need carry out the LTE-TDD systematic survey keeps the subframe of a TD-SCDMA who is not scheduled in each measuring period, make dual-mode terminal can in the subframe that it is not scheduled, carry out the LTE-TDD systematic survey.For the data that originally need to transmit in this this subframe of not being scheduled, can be dispatched in another subframe in the same frame or other frame and transmit, since every one section measuring period time corresponding just need keep a subframe that is not scheduled, therefore, can not influence the normal transmission of data.
Be similar to first kind of situation, under second kind of situation, also can adopt following method provided by the invention to carry out the selection of dual-mode terminal:
At first, distribute different integer M for different dual-mode terminals; Wherein, 0＜=M＜N;
Then, for each dual-mode terminal, when the eligible SFN mod of frame number SFN N=M, give described dual-mode terminal with a uncomfortable degree of subframe in this frame.
Step 204: described needs carried out LTE-TDD systematic survey dual-mode terminal and carry out the LTE-TDD systematic survey in the times that it is not scheduled.
Before this step, Node B need notify dual-mode terminal to carry out the LTE-TDD systematic survey usually.When specific implementation, Node B can notify according to mode same as the prior art and need carry out LTE-TDD systematic survey dual-mode terminal and carry out the LTE-TDD systematic survey, for example: by existing measuring command notice dual-mode terminal, do not repeat them here.
So far, finish dispatching method of the present invention.
As seen from the above-described embodiment, dispatching method provided by the invention, by being provided for carrying out the measuring period of LTE-TDD systematic survey, and definite dual-mode terminal that need carry out the LTE-TDD systematic survey, then when dispatching, for each dual-mode terminal that need carry out the LTE-TDD systematic survey kept one period that is not scheduled in each measuring period, thereby, dual-mode terminal can carry out the LTE-TDD systematic survey in the time that it is not scheduled, and then has realized that TD-SCDMA system and LTE-TDD system coexist in same geographic area.
For the TD-SCDMA system and the LTE-TDD system that are operated in frequency range, the present invention takes to keep in each measuring period for each dual-mode terminal that need carry out the LTE-TDD systematic survey mode of a time slot that is not scheduled 6, makes dual-mode terminal to carry out the LTE-TDD systematic survey in its time slot that is not scheduled 6; And for TD-SCDMA system that is operated in different frequency range and LTE-TDD system, the present invention keeps the subframe of a TD-SCDMA who is not scheduled for each dual-mode terminal that need carry out the LTE-TDD systematic survey in each measuring period, thereby dual-mode terminal can carry out the LTE-TDD systematic survey in the subframe that it is not scheduled.
Enforcement of the present invention need not the intervention of dual-mode terminal, also need not extra signaling support, and realization is simple, cost is low.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
