Abstract

The utility model discloses a wireless transmitting/receiving unit (WTRU) used for survey report; the WTRU is used for the survey report in an evolution general land radio access network (E-UTRAN) and regular survey report triggered by events. The wireless transmitting/receiving unit (WTRU) monitoring comes from the special reference signal of a service community and communities nearby, to detect report events defined by E-UTRAN. Once the report events are detected, WTRU sends the survey report to the network. The survey value can be referred to the signal receiving quality (RSRQ). Once the report events are detected, WTRU can regularly send the survey report triggered by the events. WTRU can send dispatching request to the network for the regular survey report triggered by the events. If the regular survey report triggered by the events is terminated before the times is set, WTRU can send the termination instruction. If more reports need to be sent after a specified number of regular reports are sent, WTRU can send the delay request.

Description

Be configured in EUTRAN, carry out measurement report to support the ambulant WTRU of WTRU

Technical field

The application relates to radio communication.

Background technology

Follow the trail of third generation partner program (3GPP) Long Term Evolution (LTE) and insert (E-UTRA) and evolved universal terrestrial radio access network (E-UTRAN) with the development evolved universal terrestrial radio.The target of E-UTRA and E-UTRAN is to obtain to support high data rate, the low radio access network that postpones, has the packet-optimized system of improved power system capacity and coverage rate.For example, in LTE, will in down link and up link, use OFDM to insert (OFDMA) and frequency division multiplexing (FDMA) air interface technologies respectively, rather than current 3GPP code division multiple access (CDMA) technology.

In order to support the mobility among the E-UTRAN, subscriber equipment (UE) need be finished the switching measurement of correlation of adjacent cell.Measurements of neighboring cells should be finished in the actual and typical scheduling scene on a large scale, and described scene is included in sub-district on the service frequency, belongs to the sub-district of another frequency or adopts the sub-district of other access technology, such as universal terrestrial radio access network (UTRAN) and global system for mobile communications (GSM)/enhanced data rates for gsm evolution (EDGE) radio access network (GERAN) system.

UE is when particular event takes place or termly to the network-reporting measurement result.In some cases, UE has the ability to start regular reporting when incident takes place.Mix report mechanism according to this, when the particular measurement result was on predetermined threshold, UE switched to the regular reporting regular reporting of Event triggered (that is, by) after this incident of report.

Major advantage by the regular reporting of Event triggered is that network need not dispose regular reporting with the unlimited time cycle.This has a benefit, has promptly significantly reduced signaling consumption, because regular reporting only just begins when needed.Another benefit is not resemble regular reporting, and UE does not need to report measurement result when network facet does not need them.

Need be characterised in that corner effect (corner effect) by a typical case of the regular reporting of Event triggered, wherein on path loss, have a sudden change.Because such accident, network wishes to receive regular reporting.These situations are more typical in some places of dense city environment.

In the measurement report canonical domain of measuring control messages, which incident UTRAN notice UE should trigger measurement report.Listed incident is the tool box that UTRAN can therefrom choose reporting event, these reporting events be finish switch estimation function or other radio network functionality needed.Measure any measuring amount of all these allocate events.

The tradition report mechanism has some problems to finish in the LTE network.At first, at present, definition does not reflect the LTE incident of LTE concrete property.For the defined incident of Universal Mobile Telecommunications System (UMTS) has reflected the channel and the frame structure of cdma system, and they cannot be applied to have the LTE system based on the frame structure of OFDM.For example, the main Common Pilot Channel of using in UMTS (CPICH) that is used for event definition no longer is applicable to the LTE system, because CPICH exists not again.Therefore reflection LTE should be provided the incident of system performance.

Secondly, in the LTE system, be not used in the mechanism of reporting by the periodic measurement of Event triggered.The mechanism of using in UMTS can not be directly used in the regular reporting by Event triggered of LTE, because in order to utilize system resource better, not being the UE assigned with dedicated channel in LTE, also no longer is that the LTE operation that comprises measurement and measurement report keeps efficient set.Therefore, shoulding be LTE provides and improves mechanism.

The 3rd, in the LTE system, there is not dedicated uplink channel.Therefore, request and scheduling uplink resources are essential with the mechanism that is used for the periodic measurement report after particular event.

The utility model content

A kind of equipment that is used for measurement report and is reported by the periodic measurement of Event triggered in E-UTRAN is disclosed.Wireless transmitter/receiver unit (WTRU) monitoring is from the cell specific reference signal of Serving cell and one or more adjacent cells, to detect by the reporting event that is the E-UTRAN definition.In case detect reporting event, WTRU just sends measurement report to network.Measuring numerical value can be Reference Signal Received Quality (RSRQ).After detecting reporting event, WTRU can send the measurement report by Event triggered termly.WTRU can send the dispatch request of being reported by the periodic measurement of Event triggered to network.If just be terminated before being reported in set point number by the periodic measurement of Event triggered, WTRU can send and stop indication.Report that if sent the regular reporting that specifies number but still needed to send more then WTRU can send and prolong request.

Embodiment

The term of hereinafter quoting " WTRU " is including, but not limited to the subscriber equipment of subscriber equipment (UE), mobile radio station, fixing or moving user unit, beep-pager, cell phone, PDA(Personal Digital Assistant), computer or any other type that can move in wireless environment.The term of hereinafter quoting " Node B " including, but not limited to the base station, site controller, access point (AP) or the interface equipment of any other type that can in wireless environment, move.

In order to support the mobility among the E-UTRAN, the cell specific reference signal that WTRU comes monitor service sub-district and one or more adjacent cells according to the configuration from E-UTRAN that provides via the measurement control messages.E-UTRAN notice WTRU should should trigger the periodic measurement report to which incident of network-reporting and which incident.Based on the measurement report of being reported, E-UTRAN finishes and switches estimation function and other radio network functionality.

Fig. 1 shows the dissimilar switching that need be supported in E-UTRAN.Switching in the LTE is in the intrasystem switching of LTE, and switching between LTE or between RAT is whereabouts and from the switching of non-LTE system (for example, UTRAN or GERAN).Switching can be to switch between interior switching of the intrasystem frequency of LTE or frequency in the LTE.Switching can be in same frequency and the switching in receiving bandwidth in the intrasystem frequency of LTE, perhaps in same frequency but the switching outside receiving bandwidth.Switching between the intrasystem frequency of LTE can be whereabouts and from the switching of another E-UTRAN Frequency Division Duplexing (FDD) (FDD) frequency, or whereabouts and from the switching of E-UTRAN time division duplex (TDD) frequency.

Three kinds of different types of measurement event in the LTE system, have been defined: reporting event between reporting event and RAT between reporting event, frequency frequently.

Reporting event reports to network in will be frequently, with to the capable estimation of the intrasystem frequency inscribe of LTE swap-in.Frequently reporting event is defined as follows in.

Frequently measurement report event-1 in: the measurement numerical value on the non-service LTE sub-district (that is adjacent cell) becomes and is better than serving measurement numerical value on the LTE sub-district with certain difference (margin).For example, if the RSRQ that the Reference Signal Received Quality (RSRQ) of adjacent cell exceeds Serving cell in measuring frequently is to preset difference, then WTRU gives network with this event report.If adjacent cell RSRQ is better than Serving cell RSRQ and becomes the redirecting cell candidate, E-UTRAN can come order WTRU to report that under connection status this incident is to prepare redirecting cell to measure difference, be lower than serving cell threshold if perhaps measure Serving cell RSRQ, can trigger interior frequently the switching.

Frequently measurement report event-2 in: measure optimum adjacent cell and exceed serving cell threshold with predetermined difference.For example, the RSRQ of adjacent cell is that best and described measurement result exceeds serving cell threshold to preset difference in other adjacent cell in measuring frequently, and the RSRQ of Serving cell is still under serving cell threshold the time, and WTRU gives network with this event report.E-UTRAN can order WTRU to report this incident under connection status, switches in the possible frequency preparing.

Frequently measurement report event-3 in: the measurement numerical value on the service LTE sub-district becomes and is better than absolute threshold.For example, if measure Serving cell RSRQ on the Serving cell minimum threshold, then WTRU gives network with this event report.E-UTRAN can order this WTRU to report this incident under connection status, to stop to prepare possible switching or redirecting cell or to measure about the WTRU of ambulant other type of WTRU.E-UTRAN also can use this event report to stop the measurement clearance distribution.In case this incident takes place, if configuration before the picture, WTRU can stop about in the ambulant all possible frequency on adjacent cell or LTE measurement between frequency, or the RAT measurements.

Frequently measurement report event-4 in: the measurement numerical value on the service LTE sub-district becomes than absolute threshold value difference.For example, if the RSRQ that measures Serving cell under serving cell threshold, then WTRU gives network with this event report.Serving cell threshold can be the minimum RSRQ value of standard definition or be the minimum RSRQ value of specific LTE cell configuration.E-UTRAN can order WTRU to report that under connection status this incident is with the order of preparing possible switching or redirecting cell or measure about the WTRU of ambulant other type of WTRU (comprise measurement clearance distribute).WTRU can give E-UTRAN with this event report under connection status, and starts the interior LTE measurement of frequency on the adjacent cell or other measurement of being ordered by E-UTRAN.

Frequently measurement report event-5 in: measure all frequently in the LTE adjacent cells RSRQ all under the adjacent cell threshold value and Serving cell RSRQ under serving cell threshold.The adjacent cell threshold value can be identical with Serving cell or can be different system configuration threshold values.E-UTRAN can order WTRU to report that under connection status this incident needs to activate LTE measurement or activation RAT measurements between frequency to indicate.This also is that E-UTRAN is begun the indication that distributes for LTE between needed frequency or RAT measurements allocating and measuring gap.

Frequently reporting event is reported to network between, to estimate switching between the intrasystem frequency of LTE.Frequently reporting event is defined as follows between.

Inter-frequency measurement reporting event-1: at present the estimation quality of the LTE frequency of using under certain threshold value and the estimation quality of untapped LTE frequency on certain threshold value.Untapped frequency is that WTRU has been measured by order but is not used in the frequency of connection.The frequency of using is the frequency that WTRU has been measured and just has been used at present connect by order.WTRU can give E-UTRAN with this event report, and E-UTRAN can order WTRU, and the general load and the resources supplIes of frequency of utilization are not finished switching between frequency based on that.

Inter-frequency measurement reporting event-2: be in the adjacent cell RSRQ that does not use the LTE frequency band and be in its ad eundem entity optimum and on dependent thresholds.This threshold value can derive based on system command by network configuration or by WTRU.E-UTRAN can order WTRU to report that under connection status LTE switches this incident between possible frequency to indicate.

Reporting event is reported to network between RAT, to estimate between LTE or to switch between RAT.Reporting event is defined as follows between RAT: at present the estimation quality of the LTE frequency of using under the certain threshold level and the estimation quality of another system (another RAT) on certain threshold level.WTRU can give this event report E-UTRAN, and E-UTRAN can consult with another system/RAT, and WTRU carries out switching between RAT with order.

For all above-mentioned measurement event, can order delayer (hysteresis) and/or timer to trigger measurement by E-UTRAN to avoid ping-pong.

Switch for LTE between frequency, when the measurement numerical value of untapped LTE frequency band was better than the measurement numerical value of the present LTE frequency band that uses, WTRU gave network with this event report.Owing to switch (promptly between frequent frequency, switch to another frequency in the LTE system) not that system and WTRU aspect are desired, therefore should carry out measurement to LTE frequency band between untapped frequency, with guarantee carried out have under the situation that switches to untapped LTE frequency band a plurality of LTE sub-district support WTRU in this frequency band stable operation with the certain hour cycle.

For the quality of measuring the LTE frequency band better and guarantee that WTRU operates in the stability in the minimum time cycle of frequency band after LTE between frequency switches, LTE frequency quality estimation not only comprise from might originate, whole broadband powers that receive of common signal channel (co-channel) and adjacent-channel interference and thermal noise, the RSRQ measurement result that also comprises WTRU may observe sub-district, if WTRU is switched to the LTE frequency band thus, then this WTRU will have at least the minority sub-district and can carry out resident (campon) and operation with the certain hour cycle for it, and ping-pong between frequency not.The measurement numerical value of frequency band also can be E-UTRAN carrier wave received signal strength indicator (RSSI), is used to be reflected in interference and the noise that the cell load of assembling on this frequency band adds the surrounding.

For WTRU measures and estimate the quality of reception of untapped LTE frequency band, network has disposed following parameter for this measurement:

(1) minimum RSRQ threshold value; The RSRQ that measures of the sub-district of selecting for the frequency mass measurement (that is, in the sub-district that can measure in the set of cells) must be equal to or greater than minimum RSRQ threshold value;

(2) be used for the minimum of frequency mass measurement and the sub-district of optional maximum number (that is the set of cells the measured element of minimum or optional maximum number);

(3) trigger delayer and timer of measuring and the weighted value that is used to estimate the RSRQ measurement result;

(4) be used for to measure the untapped LTE band cells information of the sub-district of set of cells; This information can generate by the sub-district that detection is used for the RSRQ measurement by the E-UTRAN configuration or by WTRU.In either case, having the sub-district that is lower than the RSRQ threshold value is not included in and can measures in the set of cells.If the sub-district in the setting maximum number sub-district that can measure in the set of cells, then obtains the individual sub-district of N (N is the setting maximum number of the sub-district that is used to measure) based on the RSRQ value that measures more than qualified.

By calculating summation, derive the quality estimation value of untapped LTE frequency band, and described quality estimation value can be converted into required report measurement unit from each RSRQ result that can measure the sub-district in the set of cells.This summation can only be used the result of each common single subdistrict or can use certain weighted value to eliminate unexpected fluctuating for optimum and/or the poorest RSRQ value.Can comprise the number that to measure the sub-district for the frequency quality measurement reports of network, with the stop condition of indication after may switching to this frequency.

Explain periodic measurement reporting process below with reference to Fig. 2 and 3 by Event triggered.Frequently interior measurement report event-1 is explained this process as an example.Yet, should be noted that any one above-mentioned measurement report event can trigger the periodic measurement report, and the periodic measurement reporting process by Event triggered of Xie Shiing is that all other measurement report event are connected with in all categories here, and can be applicable to any of these measurement report event, described all categories comprises in LTE frequently/switch between frequently and LTE between/RAT between switch instances.

Fig. 2 has set forth the periodic measurement report that is triggered by frequently interior measurement report event-1.Fig. 3 is by the flow chart of the process 300 of the periodic measurement of Event triggered report in the LTE system.WTRU detects measurement report event (in this example, frequently interior measurement report event-1), (step 302).As shown in Figure 2, when the measurement numerical value on the Serving cell reference channel becomes when being higher than the reporting range value, detect reporting event at t1.WTRU will be sent to network (step 304) by the measurement report of Event triggered.WTRU checks whether regular reporting is set as zero (step 306) at interval then.If report is set as zero at interval, then do not start regular reporting and process 300 end.If report is not set as zero at interval, then WTRU begins periodic measurement report (step 308).

Carry out the periodic measurement report of predetermined number of times at appointed interval.In each periodic measurement report at interval, (t2 among Fig. 2 and t3), WTRU is sent to E-UTRAN with measurement report.

By E-UTRAN report interval and required report number are set in measuring control messages.Can for some reporting events some reports interval and parameter be set at one time.Measurement report can comprise the measurement numerical value about the sub-district in the monitored set of cells in candidate collection and/or the report difference.Monitored set of cells comprises that WTRU need finish the sub-district of measurement.

Stop the periodic measurement report after the number of times that is provided with, this number of times is specified by E-UTRAN.In addition, if satisfy the sub-district (outside the incident scope) of report criterion if, also can stop the periodic measurement report if E-UTRAN or WTRU have upgraded candidate collection based on new measurement result and estimation result or sent the measurement report of maximum number.For example, as shown in Figure 2, be lower than the reporting range value, then can stop the periodic measurement report if the measurement numerical value on the Serving cell reference channel becomes at t4.

Explained later is used to support the scheduling of resource process by the periodic measurement report of Event triggered in LTE.About measurement report and scheduling of resource three kinds of situations are arranged by Event triggered.First kind of situation is to have only an incident to be triggered at present.The secondth, triggered two or more measurement reports approximately at one time.The third situation is for regular reporting has triggered incident, and the incident that formerly is triggered has triggered reporting event before finishing.

Fig. 4 is the flow chart that is used to support under the situation of having only an incident to be triggered by the process 400 of the scheduling of resource of the periodic measurement report of Event triggered.When regular reporting is triggered (step 402), need report measurement result at specific interval.In order to carry out regular reporting, WTRU determines whether whether the cycle whether available uplink resource, described uplink resource are enough to carry periodic measurement information and described uplink resource satisfy the required report of periodic measurement report (step 404) at interval.If all these conditions all are satisfied, then WTRU is used for periodic measurement report (step 406) with described uplink resource.

If any one in these conditions all do not satisfy, then WTRU sends to dispatch request the evolved Node B (eNB) (step 408) that is used for new regular uplink resource allocation.This dispatch request can comprise the resource needed amount and the number of the report that need be sent by WTRU.The granularity of resource request (granularity) is can be in standard designated and sent with signal based on the size of the measurement report that is used for different measuring numerical value and incident by E-UTRAN.WTRU can ask a plurality of minimum particle size resources based on event number and measurement report numerical value.

Then, WTRU receives from the regular resource allocation of the up link of eNB (step 410).When eNB distributes the regular resource of up link, eNB can be based on E-UTRAN specified or Resources allocation that WTRU asks (that is, repetition number and cycle).If the resource needed amount is not pointed out that in resource request then eNB can come Resources allocation based on standard volume.WTRU uses the uplink resource that is assigned with to send measurement report (step 412).

Can before the report that specifies number, stop periodic measurement.Under these circumstances, WTRU can send to E-UTRAN with stopping indication.This termination indication can be sent to eNB together with last measurement report.Replacedly, can send the termination indication individually via L1 or L2 signaling (for example, in medium access control system (MAC) header).

When reaching the report that specifies number, may need to prolong periodic measurement.If sent the regular reporting that specifies number, but still need to send more report, then WTRU can send to eNB to prolong regular uplink resource with prolonging request.Described prolongation request can be contained in the measurement report or can send via L1 or L2 signaling.The new report number that WTRU can specify WTRU to send in prolonging request.Replacedly, if do not specify the number of report, then can distribute and the last identical number of regular reporting by eNB.

In about same Time Triggered under the situation of some incidents, the process of regular reporting and scheduling of resource is similar to process 400.The report that the different reports by Event triggered can have identical distance and/or specify number maybe can have different intervals and/or the report that specifies number.A plurality of reports can be combined in together or be reported respectively.If it is not enough to distribute to the uplink resource of WTRU at present, then can send extra resource request to E-UTRAN.

Dispatch request can be all event request resources that is triggered.Can in dispatch request each incident (if their differences) allocated resource amount and report interval.If some reports are combined in together, then should be regular reporting and ask sum with the Resources allocation amount.

If any periodic measurement report by Event triggered all need stop before predetermined number of times, then WTRU can send to eNB with stopping indication.Replacedly, WTRU can use or consume the resource that is assigned with and do not change.The uplink resource that is assigned with can not be long-lasting, and WTRU can use it for any purpose, also can it not used to save the signaling consumption between WTRU and the E-UTRAN.When finishing the report that specifies number, if any one of the periodic measurement that is triggered report need be extended, then WTRU can prolong request for this report sends.

May be the regular reporting trigger event, have reporting event trigger event end formerly to be triggered before simultaneously.Can be respectively the regular reporting request new resources request that is triggered subsequently.New report can combine with the regular reporting that is triggered before.

Fig. 5 is the block diagram of exemplary WTRU 500.This WTRU comprises measuring unit 502, controller 504 and transceiver 506.Measuring unit 502 is applicable to the measurement numerical value of measurement from the cell specific reference signal of Serving cell as indicated above and adjacent cell.Described measurement numerical value can be frequently interior measurement, inter-frequency measurement or RAT measurements.Controller 504 is applicable to aforesaid whole the measurement and reporting process of control.Controller 504 detects for the reporting event of E-UTRAN definition and via described transceiver 506 and sends measurement report.

Controller 504 can send the periodic measurement report by Event triggered as mentioned above termly.Controller 504 is applicable to that also the resource of being distributed for periodic measurement report transmission dispatch request and use by Event triggered sends the periodic measurement report by Event triggered.If just stopped the periodic measurement report by Event triggered before set point number, then controller 504 can send and stop indication.If sent the regular reporting that specifies number but still needed to send more report, then controller 504 can send and prolong request.
