Embodiment
For technical problem, technical scheme and advantage that the present invention will be solved is clearer, will combine accompanying drawing and specific embodiment to be described in detail below.
In the LTE system, the frequency (F1) at UE place promptly is the frequency at Serving cell place, and the frequency that belongs to UE is a standard, and measurement can be divided into common frequency measurement, different-frequency measure and isosystem measurement.
Serving cell is meant the sub-district at the current place of UE.
Introduce many Microcells (Pico Cell) and sub-district (Small Cell) in the LTE system, be used to promote the throughput and expansion covering of communication system.
For describing conveniently, in following examples, Microcell and sub-district are referred to as adjacent sub-district.Be referred to as for first measuring period measuring period of the prior art, passed through among the present invention to be referred to as for second measuring period measuring period of revising.
In the common frequency measurement process, if UE do not have allocating and measuring gap and discontinuous reception DRX, then first measuring period MP1 be 200 milliseconds; If UE has disposed discontinuous reception DRX, then be 200 milliseconds or DRX*5 first measuring period, and wherein, if the time span of DRX cycle is less than or equal to 40 milliseconds, be 200 milliseconds first measuring period; If the time span of DRX cycle is greater than 40 milliseconds, then be 5 times DRX cycle first measuring period.
In the different-frequency measure process, if UE do not have allocating and measuring gap and discontinuous reception DRX, then first measuring period MP1 be 240*Nfreq millisecond or 480*Nfreq millisecond; If UE has disposed discontinuous reception DRX; When DRX length is less than or equal to 80 milliseconds; Measuring period MP2 when not disposing DRX the measuring period-240*Nfreq millisecond or 480*Nfreq millisecond are identical, if DRX length surpasses 80 milliseconds, then measuring period, MP2 was the 5*Nfreq millisecond.
The embodiment of the invention provides the method for the reference signal of a kind of UE of measurement, is applied to the base station, and is as shown in Figure 1, comprising:
Send second measurement configuration to UE, indicate said UE according to appointment in said second measurement configuration second measuring period measuring adjacent cells reference signal; Wherein, said second measuring period is less than first corresponding in said first measurement configuration measuring period;
Use the technical scheme that is provided; UE is in the process that moves; After receiving second measurement configuration from the base station; Through in second measuring period shorter, adjacent sub-district being measured than first measuring period, can give the base station with more accurate reporting measuring result, make the base station to carry out the switching between the sub-district exactly for UE.
In a preferred embodiment, after the step 103, also comprise:
Reception is from said second measurement report of UE, when confirming that according to said second measurement report distance between residing position of said UE and the adjacent sub-district is more than or equal to said first distance threshold;
Form said first measurement configuration, said first measurement configuration is sent to UE.
According to the strict degree of the demand of measurement, as strict as possible to wide being followed successively by:
1, the common frequency measurement demand under the non-DRX state is the strictest, and the base station does not dispose DRX;
2, the common frequency measurement demand under the DRX state;
3, the different-frequency measure demand under the non-DRX state, the base station does not dispose DRX;
4, the different-frequency measure demand under the DRX state.
The order of the strict degree of in agreement, can making an appointment, UE adopts the frequency at stricter measurement demand measuring adjacent cells place after the indication of receiving the base station, if there is adjacent sub-district to satisfy report condition, report this neighbour sub-district by UE to the base station.
In a preferred embodiment; Second measurement configuration comprises: in said second measurement configuration; Specify UE to carry out common frequency measurement, do not dispose discontinuous reception DRX, and specify the length of said second measuring period; Proportionate relationship between perhaps said second measuring period and said first measuring period, said proportionate relationship is less than 1;
Increase cell, the information of each said adjacent sub-district of expression in said cell.
Wherein, because the base station do not dispose discontinuous reception DRX, so UE no longer calculated for first measuring period according to DRX, but confirmed the length of first measuring period according to existing protocol, and according to formula:
First measuring period * proportionate relationship=second measuring period
Calculate the length of second measuring period.
In an application scenarios, carry out the common frequency measurement under the non-DRX state in the LTE system, UE is in the mobile process; And report first measurement report to the base station always, and put down in writing the neighbor cell that satisfies report condition in first measurement report, the base station is according to roughly judging the residing position of UE from first measurement report of UE; When judging that UE is very near apart from adjacent sub-district; Revise first measurement configuration to form second measurement configuration, as shown in Figure 2, comprising:
Step 1, base station first measurement report through UE judges that UE is very near apart from adjacent sub-district Cell2 and Cell3, so first measurement configuration of revising UE to be forming second measurement configuration, so as UE can be accurately, measuring adjacent cells timely.
Step 2, base station adopt RRC to connect the information that signaling is carried adjacent sub-district of reshuffling.
Particularly, the second new measurement configuration is sent to UE in the base station, and in second measurement configuration, base station notice UE exists Cell2 and these two adjacent sub-districts of Cell3 on the frequency at Serving cell place.
Owing in existing first measurement configuration, the sign of adjacent sub-district is not set specially, therefore need in second measurement configuration, increases cell newly and represent information about adjacent sub-district Cell 2 and Cell 3.
Step 3, UE reshuffles completion to base station feedback RRC connection.
Step 4 after UE receives second measurement configuration, adopts stricter measurement demand, promptly adopts the common frequency measurement demand when not disposing DRX: in 120 milliseconds, measure at least 8 co-frequency cells.
Step 5, UE detects Cell2, and detects Cell 2 and in a period of time, all satisfy report condition, so UE reports second measurement report of the signal quality that comprises Cell2 to give the base station.
Step 6, handover decisions is made according to second measurement report in the base station, and UE switches to adjacent sub-district Cell2 smoothly.
UE need return the RRC connection to the base station and reshuffle the completion signaling after knowing second measurement configuration.UE has adopted short measuring period; Can in shorter measuring period, detect adjacent sub-district Cell2 and Cell3; Obtain more sampled point, can guarantee that the measurement result that UE reports is more accurate, so that the base station of network side can be made correct handover decisions in view of the above.
As UE during, can also comprise step away from Cell2:
Step 7, base station receive second measurement report from UE, confirm that according to second measurement report distance between residing position of UE and the adjacent sub-district is more than or equal to first distance threshold; Second measurement configuration of revising UE sends to UE to form first measurement configuration with said first measurement configuration.
Step 8, UE returns to original measurement demand according to first measurement configuration that receives, and is in the less measurement pattern of power consumption once more.
In a preferred embodiment, second measurement configuration comprises: in said second measurement configuration, specify UE to carry out common frequency measurement, disposed in order to calculating the discontinuous reception DRX of said first measuring period,
And specify the length of second measuring period, the proportionate relationship between perhaps said second measuring period and said first measuring period, said proportionate relationship is less than 1;
Increase cell, the information of each adjacent sub-district of expression in said cell.
Owing to disposed discontinuous reception DRX, so UE can directly calculate for first measuring period according to DRX; Again according to formula: first measuring period * proportionate relationship=second measuring period
Calculate the length of second measuring period.
Perhaps, UE directly confirms the length of second measuring period according to the appointment in second measurement configuration, and only need satisfy condition: the length of second measuring period is smaller or equal to first measuring period that calculates according to DRX.
UE measures with adjacent sub-district frequently; If need satisfy existing measurement demand; Then: in the first measuring period DRX*5=80*5 millisecond=400 milliseconds; Accomplish to be measured received power RSRP and the quality of reception RSRQ of reference signal of the reference signal of 8 co-frequency cells by UE, the physical layer of UE need be in 400 milliseconds sends to first measurement report high level of UE.
In an application scenarios, carry out the common frequency measurement under the DRX state in the LTE system, a sub-district of base station administration is a Serving cell, UE is in connection status in Serving cell.
First measurement configuration when judgement UE is very near from adjacent sub-district, is revised to form second measurement configuration according to roughly judging the residing position of UE from first measurement report of UE in the base station, comprising:
Step 1, base station first measurement report through UE judges that UE is very near from adjacent sub-district Cell2 and Cell3, so first measurement configuration of revising UE to be forming second measurement configuration, so as UE can be accurately, measuring adjacent cells timely.
Step 2, the second new measurement configuration is sent to UE in the base station, and in second measurement configuration, base station notice UE exists two adjacent sub-district-Cell2 and Cell3 on the frequency at Serving cell place.
In second measurement configuration, specify UE to carry out common frequency measurement, dispose DRX, specify the concrete numerical value of second measuring period, the proportionate relationship between perhaps said second measuring period and said first measuring period;
Concrete, can set for second measuring period is 240 milliseconds, perhaps, proportionate relationship is 0.6.
Owing in existing first measurement configuration, the sign of adjacent sub-district is not set specially, therefore need in second measurement configuration, increases cell newly and represent information about adjacent sub-district Cell 2 and Cell 3.
Step 3 after UE receives second measurement configuration, adopts stricter measurement demand, in 240 milliseconds, measures several co-frequency cells.
Step 4, UE detects Cell2, and detects Cell 2 and in a period of time, all satisfy report condition, so UE reports second measurement report of the signal quality that comprises Cell2 to give the base station.
Step 5, base station are made handover decisions in view of the above, and UE switches to Cell2 smoothly.
UE need return the RRC connection to the base station and reshuffle the completion signaling after knowing second measurement configuration.UE has adopted short measuring period; Can in shorter measuring period, detect adjacent sub-district Cell2 and Cell3; Obtain more sampled point, can guarantee that the measurement result that UE reports is more accurate, so that the base station of network side can be made correct handover decisions in view of the above.
In the technical scheme that each embodiment provides, when UE when the adjacent sub-district, measurement configuration is revised in the base station, with indication UE adjustment measurement demand, at this moment, UE need expend more power and go measuring adjacent cells, but this can guarantee that UE obtains accurate measurement result.The base station during away from adjacent sub-district, is adjusted measurement configuration at UE once more, makes UE recover original measurement demand to reduce power consumption.
In a preferred embodiment, indicate said UE according to appointment in said second measurement configuration second measuring period measuring adjacent cells reference signal, comprising:
According to said first measuring period and said proportionate relationship in said second measurement configuration, calculate said second measuring period by said UE.
Shorten the measuring period of UE; The adjacent sub-district of measurement that can be more frequent can be found adjacent adjacent sub-district or macrocell faster, obtains many sampled points; Make measurement result more accurate; The handover decisions that second measurement report that the base station reports according to UE is made is also just more accurate, and UE can accomplish the switching between the adjacent sub-district smoothly, avoids UE can not in time survey the Radio Link Failure problem that adjacent sub-district causes.
