Description
Technical field
The present invention relates to the communications field, method of measurement and subscriber equipment in a kind of carrier aggregation.
Background technology
In mobile communication system, in order to satisfy the mobility requirement, when subscriber equipment (User Equipment is called for short UE) after certain sub-district and network connect, UE still needs the signal quality of its Serving cell and neighbor cell is measured, so that select proper cell to switch.With evolved Universal Terrestrial Radio Access Network network (Evolved Universal Terrestrial Radio Access Network, abbreviate EUTRAN as) be example, the detailed process that UE measures under the connected state is: network side will be measured control messages and send to UE, wherein, comprise the attribute of measuring sign (measurement identity abbreviates MID as), event type, measuring object and needing to measure in this measurement control messages; UE carries out parameter initialization according to the measurement sign of measuring in the control messages, and obtains each measuring object attribute and the measurement result separately in whole measuring objects of measuring in the control messages; UE carries out the incident assessment according to initialized parameter or predetermined threshold to the measurement result of each measuring object, and the duration by assessing the entry condition of determining to satisfy in whole measuring objects measurement event is more than or equal to the measuring object of scheduled measurement triggered time length (Time To Trigger abbreviates TTT as); UE puts into these measuring objects (this moment, measuring object corresponded to the sub-district) that satisfy the incident entry condition cell list (cells Triggered List) of the measurement sign of this incident correspondence; UE generates measurement report and measurement report is sent to network side according to the measurement result of the measuring object of determining, the measuring object that is comprised in the measurement report all is to obtain from the cell list of the measurement sign of this incident correspondence.
In order to satisfy people to the demand of high bandwidth more, LTE Advance proposes the purpose of the bigger bandwidth of method realization of employing carrier aggregation, this moment, (each carrier wave was called component carrier by a plurality of continuous or discrete carrier waves in a sub-district, Component Carrier) forms, the service of multicarrier can be provided for UE simultaneously.Component carrier can adopt the carrier wave of compatible LTE system, and this carrier wave is called the backward compatibility carrier wave; Component carrier also can adopt the carrier wave of incompatible existing LTE system, and this carrier wave is called non-backward compatible carrier waves, and this carrier wave can only be that Release 10 versions and above UE use.For the subscriber equipment of connected state, a plurality of component carriers of its work are called activation carrier wave collection or scheduling carrier wave collection or service carrier wave collection, can be divided into the up-link carrier collection of UE and the descending carrier collection of UE according to up-downgoing.Descending carrier at UE is concentrated, can also be divided into Physical Downlink Control Channel (Physical downlink control channel, abbreviate PDCCH as) carrier wave collection and Physical Downlink Shared Channel (Physical downlink shared channel, abbreviate PDSCH as) the carrier wave collection, some carrier wave may only provide PDSCH.
In LTE, UE can only be operated on the carrier wave, and this carrier wave is called Serving cell, in LTE Advance, a plurality of component carriers of work comprise one or more Serving cell, if the component carrier of work has only a Serving cell, the carrier wave that UE looks other is resource; If the component carrier of work comprises more than one Serving cell, UE need receive the system message of these several Serving cells simultaneously, and these several Serving cells have independence.
Whether carrier aggregation is continuous on frequency domain by each component carrier, can divide continuous carrier aggregation and discrete carrier aggregation, and so-called continuous carrier aggregation is meant that each component carrier is interconnective on frequency domain; Discontinuous carrier aggregation then refers to it is unconnected between each component carrier on frequency domain.Carrier aggregation by each component carrier whether in identical frequency band, the carrier aggregation and the carrier aggregation of striding frequency band (over multiple frequency bands) that can be divided into single band (single band), so-called single carrier aggregation is meant all component carriers that participate in carrier aggregation all in same frequency band, and single carrier aggregation can be that continuous carrier aggregation also can be discontinuous carrier aggregation; The carrier aggregation that what is called is striden frequency band is meant that the component carrier that participates in carrier aggregation can be derived from different frequency bands.
The measurement report that network based UE sends in carrier aggregation is a plurality of carrier waves of UE configuration effort.In existing measurement configuration, network is respectively UE allocating and measuring task according to each frequency, and UE assesses respectively and satisfies report condition on each frequency (for measurement event, the time of entry condition that refers to satisfy measurement event is more than or equal to TTT; For periodic measurement, refer to satisfy to measure reporting structural environment) the sub-district, UE sends measurement report to network side.Because the measurement of different frequent points configuration may be different from the TTT difference, the entry condition of each frequency measurement event also may be different, the time that causes UE to send the measurement report of different frequent points is different, be the measurement report that network side can not obtain the different frequent points component carrier simultaneously, this is disadvantageous to network side to the different component carrier of this UE management.Network side need increase or the deletion component carrier according to the measurement report of UE is dynamic, if network side once can only obtain the measurement report of one-component carrier wave place frequency, network side once can only be revised the configuration (increasing or deletion) of component carrier on this frequency dynamically, adopts this method network need expend the management that a large amount of space interface signalings could be realized carrier wave.Can more effectively manage the purpose of different component carriers, the measurement configuration that the needs employing is new in order to realize network side.
Problem at network side in the prior protocols in the correlation technique can not obtain different component carrier measurement reports simultaneously and can't manage different component carriers according to existing measurement report does not propose effective solution at present as yet.

For embodiments of the invention are described, at first carry out following description:
In mobile communication system, measuring object is a unit with frequency or the cell set that is positioned at frequency, measuring configuration comprises and (for example measures form that sign, measuring object, measurement report, Event triggered or periodic report) etc., wherein, measure sign and report structure (reporting configuration corresponding to a certain measuring object (measurement object) and specific measurement, be abbreviated as RC, the attribute that expression reports), the different measuring of same measuring object reports the corresponding different measurement sign of structure.Measurement configuration for event type, measurement reports structure corresponding one by one with measurement event (this moment one measure sign described a measuring object and corresponding with it measurement event), and the present measurement event that defines generally comprises the duration of entry condition of lag parameter Hys, incident of the entry condition of incident, the certain threshold Thresh that leaves condition, incident, incident and the side-play amount Offset of incident etc.
In order to satisfy the mobility requirement of UE under the connected state, require UE that the measuring object that satisfies the incident entry condition is measured and reported to Serving cell and adjacent sub-district, some measurement event have been defined at present to Serving cell, for example, the entry condition of definition measurement event is that the signal quality of Serving cell is higher than predetermined threshold, or the signal quality of Serving cell is lower than predetermined threshold; To the measurement event of adjacent sub-district, for example, the entry condition of definition measurement event is that the signal quality of adjacent sub-district is higher than a certain threshold value, or the signal quality of adjacent sub-district is than the high predetermined side-play amount of signal quality of current service cell.
For the measurement report of Event triggered, have two kinds to report form: a kind of is that the Event triggered single reports the measurement report of Event triggered (or be called); Another kind is that Event triggered periodically reports.The Event triggered single reports and is meant that network side has disposed the entry condition of incident for certain UE, after UE detection and assessment measuring object satisfy the entry condition of incident, the measuring object that satisfies the incident entry condition is put into the cell list of the measurement sign of this incident correspondence, only report the one-shot measurement report, the measuring object that this report comprises all obtains from cell list.If in certain time of back, there is new measuring object to satisfy the entry condition of this incident again, UE puts into new measuring object the cell list of the measurement sign of this incident correspondence, report simultaneously new measurement report once more, the measuring object that new measurement report comprises all from this moment cell list obtain, report this moment number of times still for once.
Event triggered periodically reports and is meant that network side has disposed the entry condition of incident for certain UE, after UE detection and assessment measuring object satisfy the entry condition of incident, the measuring object that satisfies the incident entry condition is put into the cell list of the measurement sign of this incident correspondence, reporting measurement reports repeatedly, the times of reporting and the time interval dispose by network side, and the measuring object that the measurement report that at every turn reports comprises all is to obtain from the current cell list that gives the correct time.In the process that this repeatedly reports or after repeatedly reporting end, if there is new measuring object to satisfy the entry condition of incident, UE reports number of times with replacement, new measuring object is put into the cell list of the measurement sign of this incident correspondence, according to the time interval of setting with report the orderly once more reporting measurement result of number of times, the measuring object that each measurement report comprises all is to obtain from the current cell list that gives the correct time then.
To the measurement of measuring object, different systems adopts different method of measurement, all is signal qualitys of reflection sub-district.In LTE, UE measures is the power (Reference Signal Received Power abbreviates RSRP as, and unit is dBm) of the reference signal that receives or quality (the Reference Signal Received Quality of the reference signal that UE receives, abbreviate RSRQ as, unit is dB).In WCDMA, that UE measures is received power (the Received Signal Code Power of Common Pilot Channel, be called for short RSCP, unit is dBm) or the Ec/No of Common Pilot Channel (refer to behind the transmitting terminal spread spectrum on every code channel the energy of each chip and the ratio of band limited white noise power spectral density), unit is dB.UE needs the measurement result of more same type when comparing the signal quality of different districts.When the assessment measuring object satisfies the incident entry condition, complete description to this measuring object not only comprises RSRP or the RSRQ that UE records, specific side-play amount (the frequency specific offset of frequency that also comprises this measuring object, abbreviation Ofn), specific side-play amount (the cell specific offset in sub-district, be called for short Ocn), with the A4 incident that defines among the LTE is example: entry condition is that the signal quality of adjacent sub-district is higher than a certain threshold value, its concrete mathematical description is Mn+Ofn+Ocn-Hys＞Thresh, and Mn is RSRP or the RSRQ that UE records adjacent sub-district in the formula.
