Optionally, when the duration of the first unlicensed spectrum resource is not less than measurement duration thresholding, user equipment judgement is surveyed Whether the physics duration of one unlicensed spectrum resource of flow control is greater than measurement delay thresholding, measures the object of the first unlicensed spectrum resource It is a length of when reason to reach from this initial position to first unlicensed spectrum resource duration measured of the first unlicensed spectrum resource Measure the physics duration between the position of duration thresholding.When the physics duration for measuring the first unlicensed spectrum resource is not more than measurement Delay gate is prescribed a time limit, and the first reference signal that user equipment sends base station in the first unlicensed spectrum resource measures, and Measurement result progress layer 3 is filtered；It prescribes a time limit, uses when the physics duration for measuring the first unlicensed spectrum resource is greater than measurement delay gate Family equipment ignores the measurement result of the unlicensed spectrum resource measured；Alternatively, when the first unlicensed spectrum resource of measurement Physics duration be greater than measurement delay gate prescribe a time limit, user equipment by the measurement result of the first unlicensed spectrum resource measured into Row layer 3 filters.Wherein, duration thresholding is measured, to can be derived that the first unlicensed spectrum resource required for accurate results Shortest time；Measurement delay thresholding, when to can be derived that accurate results, when the first unlicensed spectrum resource, can continue Longest physical time.It measures duration thresholding and measurement delay thresholding can be by eNB by signal deployment, it can also be preparatory by UE Setting.

It should be noted that a length of natural duration when physics in the embodiment of the present invention.

Optionally, when base station sends the second reference signal in the second unlicensed spectrum resource, user equipment receives institute State the second reference signal that base station is sent in the second unlicensed spectrum resource；Then, the second reference signal is measured, the Two unlicensed spectrum resources are the unlicensed spectrum resource that base station does not compete.User equipment measurement is in send that position sends the The energy value of two reference signals, sending position is the position that base station sends the second reference signal in the second unlicensed spectrum resource It sets, sends position and determined according to the configuration information that base station is sent.Then judge measurement the second reference signal energy value whether Greater than threshold value, when the energy value of second reference signal of measurement is greater than threshold value, user equipment determines the institute of measurement Stating the second reference signal is available reference signal；When the energy value of the second reference signal of measurement is not more than threshold value, user Equipment determines that the second reference signal of measurement is interference signal.

503, user equipment sends measurement report to base station according to measurement result.

Wherein, measurement report carries in the radio resource control RRC signaling that the user equipment is sent.

Optionally, measurement result includes meeting preset condition or being unsatisfactory for preset condition, and preset condition is to preset.With With preset preset condition and two kinds of measurement reports of preset condition can be unsatisfactory in the equipment of family, user equipment is according to measurement result to base It stands and sends corresponding measurement report；Alternatively, only a kind of preset measurement report, user equipment send to base station and measure in user equipment It include different measurement results in report.

It should be noted that further including the other information of the unlicensed spectrum resource of measurement in measurement report, for example, non-award The mark of frequency spectrum resource affiliated subdistrict is weighed, can be pre-configured with by the configuration information that base station is sent.

Since the cell signal of unlicensed spectrum is not continuous, coverage area of the UE in the cell signal of unlicensed spectrum It is interior, the signal of cell also can be not necessarily real-time monitored, so UE cannot carry out the cell signal quality of unlicensed spectrum Measurement.Compared with prior art, the information for the first unlicensed spectrum resource that UE reception base station is sent in the embodiment of the present invention is right The first reference signal that base station is sent in the first unlicensed spectrum resource measures, and is sent according to measurement result to base station Measurement report.UE, can be in the first unlicensed spectrum resource after the information for receiving the first unlicensed spectrum resource One reference signal quality measures, and realizes measurement of the UE to the cell signal quality of unlicensed spectrum.

Further embodiment of this invention provides a kind of method for measuring cell signal quality, base station is used for, as shown in figure 8, institute The method of stating includes:

601, base station sends the information of the first unlicensed spectrum resource to user equipment (UE).

Wherein, it is the unlicensed spectrum resource that user equipment (UE) competes that the first unlicensed spectrum resource, which is base station,.

Optionally, base station can send media access control control unit MAC CE signaling or physical down control letter to UE Road PDCCH signaling.MAC CE signaling or PDCCH signaling carry the information of the first unlicensed spectrum resource, MAC CE signaling format To preset.

602, base station sends the first reference signal in the first unlicensed spectrum resource.

Wherein, base station can also send the second reference signal, the second unlicensed spectrum in the second unlicensed spectrum resource Resource is the unlicensed spectrum resource that base station does not compete.

Optionally, the second reference signal is arranged when sending the second reference signal in the second unlicensed spectrum resource in base station The interference level for sending position and the second unlicensed spectrum threshold value, in the previous moment for sending position, detection second is non- Authorize the interference level of frequency spectrum.When interference level is greater than the threshold value of interference level, the second reference is not sent sending position The interference level of the second unlicensed spectrum is detected in next previous moment for sending position in signal, base station；When interference level not Greater than interference level threshold value when, base station send position send the second reference signal.

603, base station receives the measurement report that user equipment (UE) is sent.

Wherein, to include user equipment non-award base station first according to the information of the first unlicensed spectrum resource measurement report The measurement result that the first reference signal sent on power frequency spectrum resource measures.

It should be noted that can be determined the need for according to the result of report after eNB receives the measurement report that UE is sent For the cell of the unlicensed spectrum of UE activation measurement.

Since the cell signal of unlicensed spectrum is not continuous, coverage area of the UE in the cell signal of unlicensed spectrum It is interior, the signal of cell also can be not necessarily real-time monitored, so UE cannot carry out the cell signal quality of unlicensed spectrum Measurement.Compared with prior art, the information of the first unlicensed spectrum resource is sent to UE by base station in the embodiment of the present invention, and The first reference signal is sent in first unlicensed spectrum resource；When UE sends measurement report, measurement report is received.UE is being received To after the information of the first unlicensed spectrum resource, the first reference signal quality in the first unlicensed spectrum resource can be carried out Measurement, realizes measurement of the UE to the cell signal quality of unlicensed spectrum.

Further embodiment of this invention provides a kind of method for measuring cell signal quality, for UE to the small of unlicensed spectrum The measurement that area's signal quality carries out, worked with UE is on the authorization frequency spectrum of eNB (Evolution Node B, evolution base station) Example, when existing authorization frequency spectrum resource is unable to satisfy UE demand, eNB is that UE increases unlicensed spectrum resource, and the present invention is implemented Example is by taking eNB only sends reference signal in the unlicensed spectrum resource competed as an example, as shown in Figure 9, which comprises

701, evolution base station eNB is that user equipment (UE) increases unlicensed spectrum resource.

Wherein, eNB carries out data transmission according to present case to determine whether needing to increase unlicensed spectrum resource for UE, For example, the portfolio of UE is bigger, the cell of existing authorization frequency spectrum is unable to satisfy the demand of demand data transmission；Alternatively, eNB Heavier loads, when needing unlicensed spectrum resource to share a part of flow, eNB can for UE increase unlicensed spectrum Resource.

702, eNB is the cell that UE configures unlicensed spectrum.

Wherein, eNB needs to increase unlicensed spectrum resource as UE after transmitting data, to configure for UE by judging to obtain The cell of unlicensed spectrum.ENB completes to configure by RRC signaling for UE, and indicates that this cell is to have competed in the signaling Unlicensed spectrum cell, for example, in RRC signaling indicating cell ID, or the letter such as period is configured in RRC signaling Breath, user equipment can go out the cell that this cell is the unlicensed spectrum competed according to the information inference of configuration.

703, eNB is that UE competes unlicensed spectrum resource.

Wherein, base station competes unlicensed spectrum resource after the cell for configuring unlicensed spectrum for UE for UE.Unauthorized frequency The unlicensed spectrum resource that spectrum resource is divided into the unlicensed spectrum resource competed again and does not compete.Base station is UE in this step The unlicensed spectrum resource competed belongs to the cell for the unlicensed spectrum that base station in step 702 is UE configuration.

704, eNB sends reference signal in the unlicensed spectrum resource competed.

Wherein, eNB sends reference signal in the unlicensed spectrum resource competed, so that UE is in the resource competed The measurement for carrying out signal sends the mode of signal, such as sends the period etc. of signal, needs to configure in advance or pre- according to certain The mode of definition carries out.The reference signal that eNB is sent can be CRS (Cell-specific Reference Signals, it is small Area's own reference signal) or DMRS (Demodulation Reference Signal, demodulated reference signal) etc..

705, eNB sends the information of the unlicensed spectrum resource competed to UE.

Wherein, eNB needs the unlicensed spectrum that will be competed to provide after the unlicensed spectrum resource competed for UE configuration Source information notifies the UE of all cells for being configured with unlicensed spectrum, and no matter these UE for being configured with the cell of unlicensed spectrum are No be active requires to notify.The mode of notice can newly define the format of MAC CE, notify UE using MAC CE, Or use PDCCH DCI format (Digital Copyright Identifier format, digital publishing rights unique identification Accord with format) Lai Tongzhi UE, UE or the method notice using broadcast are perhaps notified by dedicated signaling such as RRC signaling.eNB The information of the unlicensed spectrum resource competed sent to UE may include the duration of the unlicensed spectrum resource competed, or The unlicensed spectrum resource start and end time etc. that person competes.It should be noted that step 704 and step 705 are not It is stringent successive to execute sequence.

706, UE receives the information of the unlicensed spectrum resource competed.

Wherein, after the information for the unlicensed spectrum resource that UE reception competes, judge the unlicensed spectrum competed Whether cell activates.The cell needs of unlicensed spectrum can just carry out data transmission upon activation, if the unauthorized frequency competed The cell of spectrum has activated, then UE listens to PDCCH (physical down control letter according to the unlicensed spectrum resource information competed Road) scheduling information and according to transmitting scheduling information data；It, cannot be into if the cell of the unlicensed spectrum competed does not activate The transmission of row data.

It should be noted that whether the cell no matter eNB is the unlicensed spectrum that UE is competed activates, eNB is arrived in competition After unlicensed spectrum resource, the unlicensed spectrum resource information that notice UE is competed is required, UE competes eNB for UE non- The cell signal quality of authorization frequency spectrum measures.

707, UE measures the eNB reference signal sent in the unlicensed spectrum resource competed.

It should be noted that UE measures the eNB reference signal sent in the unlicensed spectrum resource competed When, the unlicensed spectrum resource competed for needing to measure meets measurement demand, that is, the unlicensed spectrum money competed measured The duration in source is not less than measurement duration thresholding, and the total physics duration measured can just obtain accurate no more than measurement delay thresholding Measurement result.Measuring duration thresholding and measurement delay thresholding be able to can also be set in advance by eNB by signal deployment by UE It sets.

Wherein, it if one section of unlicensed spectrum resource that base station competes is not able to satisfy measurement duration thresholding, needs Accurate results can just be obtained by measuring in multistage unlicensed spectrum resource.Meanwhile if multistage unlicensed spectrum resource object Duration is managed in measurement delay thresholding, then UE can measure to obtain precise measurement knot in multistage unlicensed spectrum resource Fruit；If the physics duration of multistage unlicensed spectrum resource is more than measurement delay thresholding, UE needs restart to measure, and will Accumulative measurement duration is reset before.Measurement delay gate is limited the use of cannot be too long in the physical time delays that limitation UE is measured, physics Overlong time then will lead to measurement result failure.

For example, as shown in Figure 10, T1, T2 and T3 are the unlicensed spectrum resource durations that base station competes.If T1 is greater than Equal to measurement duration thresholding, then UE can obtain accurate measurement result in this section of resource of T1.If T1 is less than measurement duration door Limit, then UE needs continue to measure in this section of resource of T2, if T1+T2 be more than or equal to measurement duration thresholding, UE T1+T2 this two Can Duan Ziyuan obtain whether the physical time that accurate measurement result also needs to measure from T1 to T2 is less than or equal to measurement delay Thresholding.UE measures physical time from T1 to T2, i.e. t2 this period, if is less than or equal to measurement delay thresholding, if t2 is small In being equal to measurement delay thresholding, then UE this two sections of resources can obtain accurate measurement result in T1+T2；If t2 is greater than measurement Postpone thresholding, then UE needs to abandon the measurement result obtained in this section of resource of T1 or UE for the measurement knot in this section of resource of T1 Fruit is still used as normal outcome to be handled, and then UE will start to measure and recalculate survey in the resource that T2 this section competes Measure duration.If T1+T2 is greater than measurement duration thresholding, UE can compare measurement in the lucky position for meeting measurement duration thresholding Postpone thresholding, that is, when UE measures T21 in T2, the duration of this two sections of resources of T1+T21 meets measurement duration thresholding just, then UE need by from T1 to T21 the physics duration of this section of resource with measurement postpone thresholding be compared；Remaining duration in T2, i.e., T22 can be used as the effective time measured next time.Same reason, if T1+T2 is still unable to satisfy measurement duration door Limit then needs relationship that is this section of resource of T3 is cumulative up, while needing to compare t1 and measurement delay thresholding.

For example, as shown in figure 11, T1, T2 and T3 are the unlicensed spectrum resource durations that base station competes, duration door is measured It is limited to t, measurement delay gate is limited to t '.UE on the left of the unlicensed spectrum measure, a length of T1's competes when measuring first Unlicensed spectrum resource, since T1 is less than t, then UE precise results in order to obtain, the competition of a length of T2 is arrived when needing to continue measurement Unlicensed spectrum resource, judging that T1+T2 is greater than measurement duration thresholding t, and when actually T1+T2 ' can meet measurement Long thresholding, and the physics duration of measurement process is less than measurement delay gate and is limited to t ', then UE obtains primary essence in the range of T1+T2 True measurement result.After obtaining accurate measurement result, the unlicensed spectrum resource of Shi Changwei T2 competed is also remaining, So UE can when a length of T2 remaining time of the unlicensed spectrum resource competed be considered as measurement next time and start.Under In one-shot measurement, due to when a length of T2 remaining time of the unlicensed spectrum resource competed be less than t, UE needs clock synchronization a length of The unlicensed spectrum resource of T3 competed measures, but UE is obtained according to T3 judgement, in the physics duration of measurement process Reach measurement delay gate when being limited to t ', is unable to satisfy measurement duration duration thresholding this period of (T2-T2 ')+T3 ', at this time UE Way there are two types of: first, t limitation range in, measurement result is considered as normal measurement result, and is handled；Second, UE By from when a length of T3 competition to unlicensed spectrum resource start time enter a new wheel measurement.In second of processing method In, UE for (T2-T2 ') measurement processing method also there are two types of: first, UE loses the measured value of this part, second, UE is still Using this part measured value as normal value processing.

Optionally, the method for determining available unlicensed spectrum resource, can also be aobvious by MAC CE or PDCCH for eNB Formula informs that the unlicensed spectrum resource which specific section of UE competes can be in conjunction with the available unlicensed spectrum resource of composition；Or Person, eNB combine the rule for forming available unlicensed spectrum resource by the unlicensed spectrum resource that RRC information informing UE is competed Then, such as the number of segment of the unlicensed spectrum resource that competes, the unlicensed spectrum resource that competes allow to be spaced.

708, UE filters measurement result progress layer 3.

Wherein, layer 3 be filtered into the density of average summation or the bandwidth according to shared by resource rope and/or measuring reference signals into Row weighted sum etc..

709, UE sends measurement report to eNB.

Wherein, it after UE carries out the filtering of layer 3 according to measurement result, sends and surveys to base station when meeting measurement report and requiring Amount reports that the measurement situation containing unlicensed spectrum in measurement report, measurement report can pass through the up-link carrier for authorizing frequency spectrum It sends.

710, eNB receives the measurement report that UE is sent.

It should be noted that further including the other information of the unlicensed spectrum resource of measurement in measurement report, for example, non-award The mark for weighing frequency spectrum resource affiliated subdistrict, can be pre-configured with by base station in the configuration information that step 702 is sent.

It should be noted that can be determined the need for according to the result of report after eNB receives the measurement report that UE is sent For the cell for the unlicensed spectrum that UE activation has measured.Or if the cell of unlicensed spectrum has activated, eNB can be with Judge whether to discharge or replace the cell of the unlicensed spectrum according to measurement result.

Since the cell signal of unlicensed spectrum is not continuous, coverage area of the UE in the cell signal of unlicensed spectrum It is interior, the signal of cell also can be not necessarily real-time monitored, so UE cannot carry out the cell signal quality of unlicensed spectrum Measurement.Compared with prior art, the embodiment of the present invention provide in eNB by configuration information and the unlicensed spectrum resource that competes Information is sent to UE, and sends the first reference signal in the unlicensed spectrum resource competed；UE receives the configuration that eNB is sent The information of information and the unlicensed spectrum resource competed, the competition that eNB is sent in the unlicensed spectrum resource competed To reference signal measure, and according to measurement result to eNB send measurement report.UE receive compete it is unauthorized After the information of frequency spectrum resource, the reference signal quality in the unlicensed spectrum resource competed can be measured, be realized Measurement of the UE to the cell signal quality of unlicensed spectrum.

Further embodiment of this invention provides a kind of method for measuring cell signal quality, for UE to the small of unlicensed spectrum The measurement that area's signal quality carries out, by taking UE work is on the authorization frequency spectrum of eNB as an example, when existing authorization frequency spectrum resource can not expire When sufficient UE demand, eNB is that UE increases unlicensed spectrum resource, and the embodiment of the present invention is with eNB simultaneously in the unauthorized frequency competed For sending reference signal on spectrum resource and the unlicensed spectrum resource not competed, as shown in figure 12, which comprises

For example, eNB is respectively with the fixed period in the unlicensed spectrum resource competed and the unauthorized frequency not competed Reference signal is sent on spectrum resource, but the fixed cycle that reference signal is sent in the unlicensed spectrum resource not competed is small In in the unlicensed spectrum resource not competed send reference signal fixed cycle, so as to reduce to this system or other be The interference of system.Reference signal can be CRS, DMRS etc..ENB is in the unlicensed spectrum resource competed and what is do not competed non-award The method that power frequency spectrum resource sends reference signal needs to be allocated to UE by RRC signaling, which can be by authorizing frequency spectrum It is sent to UE.

Optionally, eNB sends the mode of reference signal in the resource not competed, can also be in regular hour window Interior selection low interfering resource emits sparse reference signal, to reduce eNB interference caused by this system or other systems as far as possible. As shown in figure 13, in the region for the transmitted on resources reference signal not competed in dotted line frame, it is assumed that eNB has in dotted line frame Three positions send reference signal, and eNB detects interference water of the unlicensed spectrum before sending reference signal position first Flat, if interference level is higher than threshold value, the position for sending reference signal is avoided in eNB selection, i.e. eNB is not being sent with reference to letter Number position send reference signal, and continue to test it is next transmission reference signal point position before interference level, if interference Level is lower than threshold value, then eNB is sending reference signal point position transmission reference signal.The threshold value of interference level is pre- by eNB If.
