The relay reception antenna unit 210 may receive the base station location information from the base station 110. [ In this case, each of the n relay receive antennas 210-n may be a directional antenna formed in a direction different from each other. For example, the n relay receive antennas 210-n may be a directional antenna formed in different directions in the vertical and / or horizontal directions. Therefore, the relay receiving antenna unit 210 can receive the base station position information, which is a directional high-frequency signal transmitted from the base station 110 located at a different height, without missing.

The relay apparatus reception signal processing unit 220 converts the base station position information received from the relay reception antenna unit 210 into a low frequency signal IF signal and converts the base station position information into a digital signal, 230). ≪ / RTI > The relay apparatus received signal processing unit 220 may include an LNA (Low Noise Amplifier), an AD converter, and the like.

For example, the relay apparatus control unit 230 can generate base station distance information using the signal power level of the base station position information. That is, the base station 110 can always transmit the base station position information of a constant power level, and a look-up table (not shown) for the change of the signal power level according to the distance is stored in the storage unit table may be stored in advance. At this time, the relay apparatus controller 230 may estimate the separation distance between the relay apparatus 120 and the base station 110 by comparing the power level of the received base station position information with the lookup table.

For example, the relay apparatus control unit 230 may generate the base station distance information using the time at which the base station position information is received. That is, the base station 110 may transmit the base station position information including information on the time when the base station position information is transmitted.

As described above, the relay apparatus control unit 230 may generate the base station distance information, but the base station distance information may be generated by the terminal 130. [ Accordingly, the relay apparatus controller 230 transmits information about the power level of the base station position information and / or the time when the base station position information is received to the relay apparatus position information so as to generate the base station distance information in the terminal 130 And transmits the data to the terminal 130. In order to reduce the calculation load of the relay apparatus control unit 230, the terminal 130 may preferably generate the base station distance information.

The relay apparatus control unit 230 includes a k-th relaying antenna 210-k that receives the base station position information among the n relaying antennas 210-1, 210-2, ..., 210- k is a natural number equal to or less than n), and generates base station direction information. For example, when the kth relay receiving antenna 210-k is moved in the horizontal direction corresponding to +60 degrees (clockwise) and the vertical direction corresponding to -30 degrees (upward) with respect to the front surface of the relay apparatus 120 The relay apparatus control unit 230 determines that the base station 110 is located in the vertical direction of +60 degrees (clockwise) in the forward direction and -30 (upward) in the forward direction of the relay apparatus 120 have. This is because the base station position information corresponds to a directional high frequency signal.

[ Also, the terminal receiving antenna unit 310 may include p terminal receiving antennas 310-1, 310-2,... 310-p (where p is a natural number of 2 or more).

First, the terminal reception antenna unit 310 may receive the relay apparatus location information from the relay apparatus 120. In this case, each of the p UE reception antennas 310-p may be a directional antenna formed in a direction different from each other. For example, the p relaying antennas 210-n may be directional antennas formed in different directions in the vertical and / or horizontal directions. It is possible to receive the relay apparatus position information, which is a directional high frequency signal, without missing.

The terminal reception signal processing unit 320 converts the relay apparatus position information received from the terminal reception antenna unit 310 into a low frequency signal IF signal and converts it into a digital signal, 330). ≪ / RTI > The terminal reception signal processing unit 320 may include an LNA (Low Noise Amplifier), an AD converter, and the like.

The terminal control unit 330 analyzes the relay apparatus location information processed by the terminal reception signal processing unit 320 and stores information on the distance between the terminal 130 and the relay apparatus 120 Quot;). ≪ / RTI > For example, the terminal control unit 330 may generate relay apparatus distance information using the signal power level of the relay apparatus position information. That is, the relay apparatus 120 can always transmit relay apparatus position information of a constant power level, and a storage unit (not shown) of the terminal 130 stores a look- up table may be stored in advance. At this time, the terminal control unit 330 may estimate the separation distance between the relay apparatus 120 and the terminal 130 by comparing the power level of the received relay apparatus location information with the lookup table.

For example, the terminal control unit 330 may generate the relay apparatus distance information using the time at which the relay apparatus position information is received. That is, the relay apparatus 120 may transmit the relay apparatus position information including information on the time when the relay apparatus position information is transmitted. At this time, the terminal control unit 330 may estimate the separation distance between the relay apparatus 120 and the terminal 130 using the time difference between the time of receiving the relay apparatus position information and the time difference of the relay apparatus position information.

The terminal control unit 330 also receives the relay station location information from the p terminal reception antennas 310-1, 310-2, ... 310-n, and h is a natural number equal to or less than p), thereby generating relay apparatus direction information. For example, when the h-th terminal receiving antenna 210-h is formed in the vertical direction corresponding to +45 degrees (clockwise) and +10 degrees (upward) corresponding to the front surface of the terminal 130 The terminal control unit 330 can recognize that the relay apparatus 120 is positioned in the horizontal direction of +45 degrees (clockwise) and the +10 degree (upward) vertical direction of the terminal 130. [ Since the relay apparatus position information corresponds to a directional high-frequency signal.

In addition, the terminal control unit 330 can estimate the position (including the altitude) of the relay apparatus 120 using the relay apparatus position estimation information (included in the relay apparatus position information). As described above, the base station position information includes information on the position of the base station 110 (for example, GPS coordinate values and the like), and the base station distance information includes information on the distance between the base station 110 and the relay apparatus 120 And the base station direction information includes information on the horizontal and / or vertical direction of the relay apparatus 120. [ Accordingly, the terminal control unit 330 can estimate the position of the relay apparatus 120 using the base station position information, the base station distance information, and the base station direction information.

On the other hand, if the base station distance information is not included in the relay apparatus position estimation information, the terminal control unit 330 uses the information on the signal power levels of the base station position information, the base station direction information, The position can be estimated. The base station 110 can always transmit base station position information of a constant power level and a lookup table corresponding to the signal power level change according to the distance of the base station position information is stored in the storage unit (not shown) up table may be stored in advance. At this time, the terminal control unit 330 may estimate the separation distance between the relay apparatus 120 and the base station 110 by comparing the power level of the received base station position information with the lookup table.

If the base station distance information is not included in the relay apparatus position estimation information, the terminal control unit 330 determines whether the base station position information, the base station direction information, and the base station position information are received from the relay apparatus 120 The position can be estimated. The terminal control unit 330 can generate the base station distance information using the time when the base station position information is received by the relay apparatus 120. [ That is, the base station 110 may transmit the base station position information including information on the time when the base station position information is transmitted. At this time, the terminal control unit 330 can estimate the separation distance between the relay apparatus 120 and the base station 110 using the time difference between the time when the base station position information is received in the relay apparatus 120 and the time difference between the base station position information and the base station position information will be.

Also, the terminal control unit 330 can estimate the location of the terminal 120 using the estimated location of the relay apparatus 120, the relay apparatus distance information, and the relay apparatus direction information. Since the position of the relay apparatus 120 is estimated as described above and information on the distances between the terminal 130 and the relay apparatus 120 and the vertical direction and the vertical direction are generated, Can be estimated.

The terminal transmission signal processing unit 340 amplifies the signal processed by the terminal reception signal processing unit 320 and processes it by processing it as an analog high frequency signal. The terminal transmission signal processing unit 340 may include a DA converter, a power amplifier, and the like.

The terminal transmission antenna unit 350 can transmit the analog high frequency signal processed by the terminal transmission signal processing unit 340 to the outside through the q terminal transmission antenna unit 350.

As described above, since the terminal position estimation system according to the present invention can estimate the terminal position in the room using a single AP (i.e., the relay apparatus 120), it is possible to accurately estimate the terminal position in the room, The position can be estimated.

However, Will be collectively referred to as being performed in the relay apparatus 120 or the terminal 130 for convenience.

In step S410, the relay apparatus 120 can receive the base station position information from the base station 110. [ In this case, the relay apparatus 120 may have n relay receive antennas, and each of the n relay receive antennas may be a directional antenna formed in different directions from each other. Accordingly, the relay apparatus 120 can receive the base station position information, which is the directional high-frequency signal transmitted from the base station 110, without missing.

In step S420, the relay apparatus 120 may generate relay apparatus position estimation information. That is, the relay apparatus 120 can generate the base station direction information by analyzing the horizontal direction and / or the vertical direction in which the kth relay receiving antenna that receives the base station position information among the n relay receiving antennas is formed. This is because the base station position information corresponds to a directional high frequency signal. Or relay apparatus 120 may analyze base station location information to generate base station distance information. For example, the relay apparatus 120 may generate the base station distance information using the signal power level of the base station position information. That is, the base station 110 can always transmit the base station position information of a constant power level, and a look-up table for the change of the signal power level according to the distance is stored in advance in the storage unit of the relay apparatus 120 May be stored. At this time, the relay apparatus 120 may estimate the separation distance between the relay apparatus 120 and the base station 110 by comparing the power level of the received base station position information with the lookup table.

In another example, the relay apparatus 120 may generate the base station distance information using the time at which the base station position information is received. That is, the base station 110 may transmit the base station position information including information on the time when the base station position information is transmitted. At this time, the relay apparatus 120 may estimate the separation distance between the relay apparatus 120 and the base station 110 by using the time difference between the time of receiving the base station position information and the time difference of the base station position information.

Alternatively, the relay apparatus 120 may transmit information on the power level of the base station position information and / or information on the time when the base station position information is received so that the terminal 130 can generate the base station distance information, (In this case, the base station distance information may not be included in the relay apparatus position estimation information).

In step S430, the relay apparatus 120 generates relay apparatus position information including the base station position information, the base station distance information, and the base station direction information, and transmits the relay apparatus position information to the terminal 130. [

In step S440, the terminal 130 may receive the relay apparatus position information from the relay apparatus 120. [ The terminal 130 may generate the relay apparatus direction information by analyzing the horizontal direction and / or the vertical direction in which the h-th terminal receive antenna receiving the relay apparatus position information among the p terminal reception antennas is formed. Since the relay apparatus position information corresponds to a directional high-frequency signal.

In step S450, the terminal 130 may generate relay apparatus distance information by analyzing the relay apparatus position information. For example, the terminal 130 may generate relay apparatus distance information using the signal power level of the relay apparatus position information. That is, the relay apparatus 120 can always transmit the relay apparatus position information of a constant power level, and a look-up table for the change of the signal power level according to the distance is stored in the storage unit of the terminal 130 And may be stored in advance. At this time, the terminal 130 may estimate the separation distance between the relay apparatus 120 and the terminal 130 by comparing the power level of the received relay apparatus location information with the lookup table.

In another example, the terminal 130 may generate relay apparatus distance information using the time at which the relay apparatus position information is received. That is, the relay apparatus 120 may transmit the relay apparatus position information including information on the time when the relay apparatus position information is transmitted. At this time, the terminal 130 may estimate the separation distance between the relay device 120 and the terminal 130 using the time difference between the time at which the relay device location information is received and the time at which the relay device location information is transmitted.

In step S460, the terminal 130 can estimate the position of the relay apparatus 120 using the base station position information (included in the relay apparatus position information) and the relay apparatus position estimation information. The base station position information includes information on the position of the base station 110 (for example, GPS coordinates, etc.), and the base station distance information included in the relay apparatus position estimation information is transmitted to the base station 110 and the relay apparatus 120 And the base station direction information includes information on the horizontal direction and / or the vertical direction in which the base station 110 is located based on the front surface of the relay apparatus 120. [ Accordingly, the terminal 130 can estimate the position of the relay apparatus 120 using the base station position information, the relay apparatus position estimation signal base station distance information, and the base station direction information.

Or the terminal 130 generates base station distance information using information on the power level of the base station position information included in the base station position information and the relay apparatus position estimation information and / or information on the time when the base station position information is received And the location of the relay apparatus 120 may be estimated using the generated base station distance information.

In step S470, the terminal 130 may estimate the position of the terminal 120 using the position of the relay apparatus 120, the relay apparatus distance information, and the relay apparatus direction information estimated in step S470. Since the position of the relay apparatus 120 has been estimated and information on the distance, horizontal direction and / or vertical direction of the distance between the terminal 130 and the relay apparatus 120 has been generated as described above, It is possible to estimate the position of the display unit 130.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood that the invention may be varied and varied without departing from the scope of the invention.
