Description
Technical field
The present invention relates to wireless communication field, relate in particular to the method for locating terminal and the equipment that are applied to multicarrier system.
Background technology
LTE-A(LTE Advanced, the evolution of LTE, wherein LTE is that the English of Long Term Evolution is called for short, i.e. Long Term Evolution) peak rate of system compares and improves a lot with LTE system, requires to reach descending 1Gbps, up 500Mbps.Meanwhile, LTE-A system requirements and LTE system have good compatibility.Based on improve peak rate, with LTE system compatible and the needs that make full use of frequency spectrum resource, LTE-A system has been introduced carrier aggregation (Carrier Aggregation, CA) technology.
Carrier aggregation technology refers to the Equipment at UE(User, subscriber equipment) a plurality of cell(of polymerization community simultaneously), a plurality of cell can provide the mechanism of data transport service simultaneously for UE.In the system of carrier aggregation, the carrier wave that each cell is corresponding can be continuous or discrete at frequency domain, for LTE system compatible, the maximum bandwidth of each member carrier is 20MHz, the bandwidth between each member carrier can be identical or different.
Under carrier aggregation, terminal works little divided into a main plot PCell(Primary Cell) and several auxiliary community SCell(Second Cell), the work of most of control and signaling has been born in main plot, as sent the uplink feedback of downlink data, CQI(Channel Quality Indicator, channel quality indication) report, ascending pilot frequency transmission etc., auxiliary community is mainly as resource, bears the function of transfer of data.
In carrier aggregation scene, due to different carrier may exist different communication environments (for example, different frequencies, or network side altogether location cause the communication environments different), may there is different uplink timing advances in same terminal therefore on different carrier waves.
When carrier aggregation, also exist the carrier wave of polymerization not to be total to the scene of location, the uplink timing advance on different carrier waves is different.If the signal to noise ratio difference of different carrier waves or Measurement bandwidth are different, also can be influential to the certainty of measurement of location.
The terminal location location technology of side Network Based comprises CELL_ID location technology and TA+AOA location technology.CELL_ID localization method is the localization method covering based on community, adopts the position of known Serving cell geography information estimating target UE.This service cell information can be by calling, paging, TA(Tracking Area, tracking area) mode such as renewal obtains.TA+AOA localization method has been considered Timing Advance (being TA, Timing Advance) and arrival bearing's's (being AOA, Angele of Arrival) factor on the basis of CELL_ID localization method, thereby reach, locates more accurately object.
Base station obtains by smart antenna the AOA that UE transmits, and UE is in take on the ray that base station is starting point, and the angle that ray is rotated counterclockwise from direct north is AOA.The principle of TA+AOA location technology is: the time difference that the acquisition of TA can be received and be sent by terminal to report UE, add base station measurement to reception and the time difference of transmission calculate (TA that the method calculates is referred to as TA TYPE1), also can by base station measurement, obtain (TA that the method calculates is referred to as TA TYPE2) by special-purpose random access procedure.TA is multiplied by the light velocity divided by 2, has represented that UE is with the distance between base station, and as shown in Figure 1, UE just, in take base station on the circumference that the center of circle, terminal and base station distance are radius, just can obtain the position of terminal according to the angle information of AOA.
Use TA+AOA method to carry out terminal positioning and relate generally to following flow process: location-server obtains the measurement capability of terminal, and determines required measuring amount, asks base station initiated measurement of correlation; Base station reports measurement of correlation result and positional information to location-server, and location-server carries out position calculation.
In TA type1, need terminal to provide measuring UE Rx-Tx time difference(is the time difference that UE receives and sends) measurement.The required precision of this measurement is as shown in 36.133 agreements:
Table 1, the requirement of UE Rx-Tx time difference certainty of measurement
Table 1 has provided the certainty of measurement requirement of UE Rx-Tx time difference when signal to noise ratio (ê s/Iot) >=-3dB.When Measurement bandwidth≤3MHz, precision is ± 20Ts; When Measurement bandwidth >=5MHz, certainty of measurement is ± 10Ts.Signal to noise ratio, lower than-3db, is not carried out required precision, means in this case, and certainty of measurement can be poor, probably do not reach ± 20Ts.
TA+AOA localization method is only applied to the localization method of ，Shi Dan community, main Serving cell at present, and the effect of location depends on the measurement effect of this community.In fact the measurement accuracy of TA and AOA can be subject to environment, signal strength signal intensity, and the impact of the factors such as interference, in different frequencies, multipath effect may be different.In poor signal quality, in the situation of the low and little bandwidth of signal to noise ratio, the precision of measurement is not high yet.After introducing multicarrier system, terminal may be simultaneously operated under many communities, at present can only be in Pcell(Primary cell, main plot) on carry out the location of TA+AOA.In the situation that the channel quality on Pcell declines, the precision of this measurement can variation.
