Description
Technical Field
The invention relates to the field of mobile communication, in particular to a method for positioning a mobile terminal by utilizing beam characteristics.
Background
With the development of mobile communication technology, mobile communication terminals are widely used in daily life, and there are many Positioning modes of mobile terminals, the most commonly used are Global Positioning System (GPS) in the united states, Global NAVIGATION Satellite System (Global NAVIGATION SATELLITE SYSTEM, GLONASS) in russia, Galileo Positioning System (GSNS) in europe, and BeiDou NAVIGATION Satellite System (BDS) in china at present. Satellite Positioning methods are mainly used in the military, and are now commonly used in civilian areas, and in mobile communication systems, in order to increase the search speed of mobile terminals and improve the Positioning accuracy, Assisted Global Positioning System (AGPS) is generally used. Although the use of satellite positioning can solve the basic positioning requirement of people, in practical use, especially indoor use, the mobile terminal cannot receive satellite signals, so that the satellite positioning mode cannot be used.
Since the satellite positioning method is not suitable for indoor positioning, solutions have also been proposed in mobile communication systems, such as Location Based Service (LBS), which have high requirements for network establishment cost and are not widely popularized in practical life. Of course, many methods for positioning a mobile terminal in a wireless manner have been proposed in the meantime, but the basic principle is to use the mobile terminal to interact with a plurality (at least 3) of base stations, and then determine the position of the mobile terminal according to the positions of the base stations and the distance between the base station and the mobile terminal. Based on the principle, the method is not particularly applied to actual engineering. The main reasons are the following:
firstly, the method comprises the following steps: the mobile terminal needs to obtain the specific positions of at least 3 base stations, and needs to consume a large amount of signaling resources, particularly, the mobile terminal needs to obtain the position information of the base stations of the adjacent cells, and the mobile terminal needs to interact with a plurality of base stations to complete the process;
secondly, the method comprises the following steps: the mobile terminal needs to acquire the distance between the mobile terminal and the base station and needs to acquire the distance of at least 3 base stations to complete positioning, so that great difficulty is brought to actual practical use, and the signaling load between the mobile terminal and the base station is increased;
thirdly, the method comprises the following steps: if the positioning of the base station to the mobile terminal is completed, information coordination is required among a plurality of base stations to complete the positioning of the mobile terminal, and the base station selected for positioning by the mobile terminal is not fixed, which increases signaling transmission among the base stations.
For the above reasons, there is no way to use the base station to determine the location of the mobile terminal.
At present, in a mobile terminal, a cell positioning mode is basically used, so that in use, the mobile terminal can only obtain an approximate location range of itself, the positioning accuracy is mainly determined by a cell coverage radius, the larger the coverage radius of a serving cell is, the more inaccurate the mobile terminal is positioned, and the positioning range is different from hundreds of meters to kilometers. In a word, no method for providing a perfect indoor positioning solution in the field of mobile communication exists at present.
In a 5G mobile communication system, due to the use of high-band radio resources, massive MIMO use is possible, and currently, in the third Generation Partnership Project (3 GPP), it is determined that FR1(Frequency Range1) and FR2(Frequency Range 2) in the 5G used band are both used with phased array antennas of massive MIMO, so in a 5G base station system, beams may be used instead of cells.
The target object positioning by utilizing the beam directivity is widely applied to the current phased array radar, but the radar system mainly uses the beam sent by the radar to determine the direction of the target object after the target object is transmitted back. In the phased array radar system, because a target object cannot acquire radar key parameters and no communication link exists, the target object cannot determine the position of the target object even if a scanning beam emitted by a radar can be checked.
With the development of mobile communication, in the current 5G system, due to high working frequency, large-scale MIMO has become one of the indispensable technologies of 5G, the phased array technology of radar is also transplanted to the 5G base station antenna system, a communication link exists between the base station and the mobile terminal, and the base station can acquire the information of the mobile terminal part, which provides conditions for the base station to position the mobile terminal.
In signal processing, the radar uses an array antenna to solve the problem of detection and positioning of a target object, but based on radar transmission beams, the target object transmits signals, and finally the azimuth angle and the distance of the target object relative to the array antenna are calculated, but the method is not suitable for positioning of a mobile terminal.

As shown in fig. 4, when the mobile terminal starts position location, the mobile terminal starts to search for a synchronization signal/Physical broadcast signal Block (SS/PBCH Block), and measures the transmission power of the SS/PBCH Block to form a measurement list;
if the mobile terminal can receive K SS/PBCH Block signals from the same antenna array, recording the received Power (SS-RSRP) of the SS/PBCH Block, respectively, representing the Power of the kth SS/PBCH received by the mobile terminal as SS _ RSRP _ K, and reporting each measured SS _ RSRP to the base station by the mobile terminal, wherein K is {1,2, ·, K };

PathLoss_k=SS_PBCH_BlockPower_k-SS_RSRP_k。
in the process of calculating the distance between the mobile terminal and the antenna, as shown in fig. 5, the mobile terminal selects the SS/PBCH Block with the strongest receiving power value, transmits a Random preamble on a Physical Random Access Channel (PRACH) corresponding to the SS/PBCH Block, and then receives a Random Access Response message (RAR) if the mobile terminal transmits an uplink preamble signal on the specific PRACH in advance by Δ T;
the base station detects the random preamble sent by the mobile terminal on the specific PRACH, and sends the detected timing offset _ time to the mobile terminal through the RAR, so that the transmission delay T between the mobile terminal and the antennadelayCan be represented as TdelayΔ T + offset _ time; and delays the transmission by TdelaySending the data to a base station;

wherein, Path _ Loss represents the Loss of the radio wave transmitted by the ith beam in the air, and Path _ i represents the Loss of the radio wave transmitted by the ith beam with a direction angle in the air.
In practical use, the position between the terminal and the antenna array is relatively fixed, and then different beams thetaiAnd phiiThe values are the same, and are marked as theta, phi and alphaiThen it is a known parameter that can be obtained during the antenna array beam scanning process. When the terminal receives a plurality of wave beams, two wave beams with the strongest signals are selected to form a two-dimensional determinant, and theta and phi are calculated; two wave beams with strongest signals are selected for positioning, and because the moving speed of the mobile terminal in the room is relatively low, the position relation between the mobile terminal and the antenna is approximately regarded as unchanged in the SSB measurement and parameter acquisition process, so that theta and phi of the two wave beams can be regarded as equal, and alpha is regarded as equal1And alpha2For known parameters, it is expressed as:
