The measurement work of the terminal to be located shown in FIG. 1 is performed by the remote unit. In the specific implementation, the measurement work of the terminal to be positioned is performed by the remote unit, and the extension unit may be used for positioning. The terminal performs measurements. Then, if the measurement work of the terminal to be located is performed by the extension unit, FIG. 2 exemplarily shows another distributed system network topology diagram provided by the embodiment of the present application, as shown in FIG. 2 .

Embodiment 1 and FIG. 3 exemplarily show a schematic diagram of a positioning method provided by an embodiment of the present application. As shown in FIG. 3, the method includes the following steps:

S101: The baseband unit sends configuration information to the measurement unit, where the configuration information includes frame number information of the baseband unit, time-frequency resource information to be measured, and measurement type information of the terminal to be located.

S102: The measurement unit receives configuration information sent by the baseband unit.

S103: The measurement unit performs measurement on the terminal to be measured according to the configuration information to obtain a measured value;

S104: The measurement unit sends the measurement result to the baseband unit, where the measurement result includes the measurement value, the identifier of the remote unit, and the time-frequency resource information of the terminal to be located;

S105: The baseband unit receives the measurement result sent by the measurement unit, where the measurement result includes the measurement value, the identifier of the remote unit, and the time-frequency resource information of the terminal to be located, and the measurement value is obtained by the measurement unit according to the configuration information.

S106: The baseband unit determines, according to the time-frequency resource information of the terminal to be located in the measurement result, multiple measurement results of the terminal to be located, and the measurement result is used for positioning the terminal to be located.

In S101, the baseband unit sends configuration information to the measurement unit, where the configuration information includes frame number information of the baseband unit, time-frequency resource information to be measured, and measurement type information of the terminal to be located. In a specific implementation, the configuration information may further include resource configuration information required to parse the measurement type information of the terminal to be located in the cell carried by the measurement unit. The measurement type information may be the received power in the specific implementation, or may be the arrival angle and the time advance amount, and the measurement type information is the received power or the arrival angle and the time advance amount, which is determined by which positioning algorithm is adopted, for example, if Using the field strength fingerprint method, then the measurement type information is the received power. If the AOA+TA (AOA: Angle of arrival, TA: timing advance, time advance) algorithm is used, then the measurement type information is reached. Angle and time advance.

After S101, before S102, the method further includes: the measuring unit receives the frame number synchronization request sent by the baseband unit; and the measuring unit completes the frame number synchronization with the baseband unit according to the frame number synchronization request. Specifically, after the measurement unit receives the frame number synchronization request sent by the baseband unit, the measurement unit first synchronizes the frame number of the local measurement unit with the frame number of the baseband unit according to the frame number synchronization request, because all measurement units under the common cell Both are synchronized with the baseband unit frame number of the local cell. Therefore, the frame numbers of the respective measurement units under the common cell can be guaranteed to be synchronized. Since the baseband unit knows which terminal data is carried by the frame number, it can ensure that the measurement result sent by the subsequent measurement unit to the baseband unit belongs to which terminal, thereby ensuring the correct correspondence between the measurement result of the subsequent measurement unit and the terminal. Wherein, the measuring unit is a remote unit; or the measuring unit is an expansion unit connected to the remote unit.

The S201 receives the configuration information sent by the baseband unit, where the measurement unit directly receives the configuration information of the baseband unit, the remote unit receives the configuration information about the baseband unit forwarded by the extension unit, and the remote unit receives the configuration information. The configuration information about the baseband unit forwarded by the superior remote unit.

In S103, the measuring unit performs measurement on the terminal to be measured according to the configuration information, and specifically, if the measurement type is the arrival angle and the timing advance, the measurement unit receives the positioning signal of the terminal to be located reported by the remote unit, And parsing each received positioning signal to obtain time information and/or angle information of each positioning signal arrival. Another case: If the measurement type is the measurement process of the received power, it will not be described here.

S103 specifically includes: the extension unit receives IQ data of the remote unit corresponding to the extension unit; and the extension unit performs measurement on the terminal to be measured according to the configuration information and the IQ data to obtain a measured value. Specifically, the remote unit receives the positioning signal sent by the terminal to be located, that is, IQ (in-phase quadrature) data, and sends the IQ data to the extension unit, and the extension unit transmits the IQ data and the baseband according to the remote unit. The configuration information sent by the unit is measured by the terminal to be measured to obtain a measured value. The work of measuring the location of the terminal according to the configuration information of the baseband unit can be performed by the remote unit or by the extension unit. Based on this, it can be seen that the solution of the present application has flexibility.

In S104, the measurement unit sends the measurement result to the baseband unit, and the measurement result includes the measurement value, the identifier of the remote unit, and the time-frequency resource information of the terminal to be located. Specifically, the measurement unit includes the measurement value and the identifier of the remote unit. The time-frequency resource information of the terminal to be located is sent to the baseband unit, where the measured value may be time information and/or angle information of the arrival, or may be received power. Since the measurement unit transmits the measurement result to the baseband unit, instead of transmitting the front end signal, that is, the IQ signal, to the baseband unit through the remote unit as in the prior art, simply transmitting the IQ signal will occupy too many front ends. The bandwidth is returned, which affects the application extension. However, this application only transmits the measurement result to the baseband unit, which can overcome the problem that the front end occupies too much backhaul bandwidth.

In S106, the baseband unit determines a plurality of measurement results of the terminal to be located according to the time-frequency resource information of the terminal to be located in the measurement result, and the measurement result is used for positioning the terminal to be located. Specifically, the baseband unit determines, according to the time-frequency resource information of the same to-be-located terminal, the plurality of remote units to determine a plurality of measurement results of the same terminal to be located, and determine the number of the terminal to be located. The measurement result can ensure that the positioning operation is performed on the terminal to be positioned according to the plurality of measurement results of the terminal to be located.

After S106, the method further includes: performing positioning operations according to multiple measurement results of the terminal to be located, which can be implemented in the following two manners:

The first baseband unit determines the location information of the terminal to be located according to the multiple measurement results of the terminal to be located. Specifically, the baseband unit performs a positioning operation according to multiple measurement results of the terminal to be located, and outputs the positioning result to determine the to-be-positioned. Location information of the terminal.

Manner 2: The baseband unit sends the plurality of measurement results of the terminal to be located to the positioning calculation server, so that the positioning calculation server determines the location information of the terminal to be located according to the plurality of measurement results of the terminal to be located. Specifically, the baseband unit sends the plurality of measurement results of the terminal to be located to the positioning calculation server, and the positioning calculation server performs a positioning operation according to the plurality of measurement results of the terminal to be located, and outputs the positioning result to determine the position information of the terminal to be located.

The positioning operation is performed according to the plurality of measurement results of the terminal to be located, and the positioning operation may be performed by the baseband unit or the positioning calculation server, and may be selected according to a specific situation to be determined by the baseband unit or the positioning calculation. The server performs the positioning operation, so based on this, the solution of the present application has flexibility.

Optionally, determining location information of the terminal to be located includes: determining, from the plurality of measurement results of the terminal to be located, M measurement results whose measurement value is greater than a threshold; determining, according to the identifier of the remote unit in the M measurement results, to be determined Location information of the bit terminal. Specifically, if there are four measurement results of the terminal to be located and the threshold is set to 1, the measurement result that the measured value is greater than 1 from the four measurement results of the terminal to be located is the first three, that is, the value of M. 3: Determine location information of the terminal to be located according to the identifier of the remote unit in the determined three measurement results. The setting of the threshold size is set according to a specific implementation situation. Specifically, after the positioning calculation server or the baseband unit receives the plurality of measurement results of the terminal to be located, the positioning quality of the terminal may be sorted according to the order of the signal receiving quality. Among the plurality of measurement results, M measurement results larger than the threshold are selected. Determining the measurement result that meets the threshold size from the plurality of measurement results according to the set threshold value, and determining the terminal to be located according to the selected measurement result that meets the threshold size and the identifier of the remote unit corresponding to the measurement result. The location information can reduce the computational complexity and improve the accuracy of the positioning.

The embodiments of the present application are further described in detail below with reference to the accompanying drawings.

In the embodiment of the present application, the distributed system coverage system adopts GSM, and the used positioning algorithm is the field strength fingerprint method. FIG. 4 exemplarily shows the measurement time diagram of the GSM system, as shown in FIG. 4 . Since the GSM system is a pure time division system, only one UE per slot per communication is in communication. For the field strength fingerprint method, the remote unit only needs to complete each remote carrier unit for each carrier of the carried cell. The received power of the time slot is measured.

The measured values are gathered together to obtain the receiving power of each remote unit in the current measurement granularity of UE0, that is, the positioning calculation server can perform the positioning operation. In the second embodiment of the present application, the configuration information includes the frame number information of the baseband unit, the time-frequency resource information to be measured, and the measurement type information of the terminal to be located, where the measurement type information in the configuration information is the received power, because the remote unit exists. The method of directly connecting to the baseband unit may also be connected to the baseband unit after being cascaded by the upper K-stage remote unit. Therefore, the configuration information received by each remote unit, including directly from the baseband unit, is also It includes configuration information from a baseband unit that has been forwarded by the upper K-class remote unit. After receiving the frame number information, each remote unit first synchronizes the local frame number of the local remote unit with the baseband unit, and since all the remote units of the shared cell are synchronized with the baseband unit of the local cell, each of the common cells The timing and frame number of the remote unit can ensure synchronization.

In the second embodiment of the present application, one cell includes 8 carriers, and each carrier adopts dual antennas (sampling rate is 1.92 M), and each channel of IQ is represented by 32 bits, and the existing distributed positioning method is adopted, and each remote unit is achieved. The front-end backhaul bandwidth required for positioning is: 8 (carrier) * 1.92 (IQ sampling rate) * 32 (IQ bit width) = 491.52 Mbps, and each remote unit used in this embodiment is required to achieve the positioning of the front end. The transmission bandwidth is: 8 (carrier) * 8 (time slot) * 8 (power intensity bit width) / 4.615 ms (length per frame) = 11 Kbps, as can be seen from the second embodiment of the present application, the application only needs to be in the remote unit Increasing the power statistics function of each time slot, the action is only a simple multiplication and accumulation, and does not bring the load pressure to the remote unit, so that the same application for realizing the distributed system positioning can be achieved, and each remote unit is achieved. The front-end backhaul bandwidth required for positioning is reduced to about 4,534 points of the prior art. It can be seen that the present application has the advantages of low cost and low bandwidth processing.

Based on the foregoing embodiment 2, the distributed overlay system of the embodiment further includes an extension unit. Therefore, the action performed by the remote unit on the measurement may also be performed by the extension unit, thereby completing the front-end independent measurement backhaul. The goal.

Embodiment 3 The whole process is similar to the above embodiment. The difference is that the remote unit receives the positioning signal of the terminal to be located, and the remote unit sends the received positioning signal to the extension unit, and the extension unit sends the positioning signal according to the received positioning signal and the baseband unit. The configuration information is measured by the measurement type information of the positioning terminal, and the measurement unit sends the measurement result to the baseband unit. The subsequent other processes are the same as those in the above embodiment, and therefore are not described herein again.

In the third embodiment of the present application, one cell includes 8 carriers, and each carrier adopts dual antennas (sampling rate is 1.92 M), and each channel of IQ is represented by 32 bits, each cell includes four extension units, and each extension unit includes 8 pulls. For remote unit accounting, the existing distributed positioning method is adopted. The front-end backhaul bandwidth between the extension unit and the baseband unit is: 8 (carrier number) * 1.92 (IQ sampling rate) * 32 (IQ bit width) * 4 (extension) The number of units is *8 (the number of remote units connected per extension unit) = 15.36 Gbps, and the backhaul bandwidth using this embodiment is: 8 (carrier) * 8 (time slot) * 8 (power intensity bit width) *4 (number of extension units) *8 (number of remote units connected per extension unit) / 4.615 ms (length of time per frame) = 3.467 Mbps. As can be seen from the embodiment of the present application, this application only needs to increase each in the extension unit. The power statistics function of the time slots, the action is only a simple multiplication and accumulation, and does not bring the load pressure to the expansion unit, so that the application for the distributed system positioning can also be implemented, and the front-end backhaul bandwidth is reduced to the prior art. One of the 4536 points, it can be seen that the application has low cost, low bandwidth Rational advantage.

In summary, according to the method of the present application, since the remote unit independently measures the measurement type of the terminal positioning, and the remote unit reports the measurement result to the baseband unit, the front-end backhaul can effectively reduce the excessive bandwidth requirement. The problem, at the same time, because the support positioning application only involves the measurement type required for positioning, the overhead is small, and the integration is convenient in the existing remote unit, and no additional cost is added. Therefore, the application has low cost and low bandwidth requirement. The advantages.

The measured value is obtained. The final measurement unit sends the measurement result to the baseband unit, where the measurement result includes the measured value, the identifier of the remote unit, and the time-frequency resource information of the terminal to be located.

A higher cost phenomenon does not increase the additional cost; on the other hand, since the measurement unit transmits the measurement result to the baseband unit, instead of the front-end signal, that is, IQ (in-phase quadrature, as in the prior art) The in-phase orthogonal signal is transmitted back to the baseband unit through the remote unit. Simply speaking, the transmission of the IQ signal will occupy too much front-end backhaul bandwidth, affecting application expansion, and the present application only transmits the measurement result to the baseband unit, which can overcome The front end occupies a problem of excessive backhaul bandwidth.
