In this article, these embodiments of the present invention may be represented individually or collectively by the term "invention", which is only for convenience, and if more than one invention is actually disclosed, it is not intended to automatically limit the scope of the application to any single invention or inventive concept.

[0042] It is suitable for indoor coverage of 5G systems, in-vehicle coverage of Internet of Vehicles, and in-car coverage of rail transit, etc., for coverage of indoor confined spaces. An antenna is installed outdoors, and the outdoor RF signal is connected to the device of the present invention through an RF cable. After amplifying the uplink and downlink RF signals, the indoor space is covered through the indoor antenna, ensuring that the indoor terminal can communicate with the outdoor base station.

[0043] The device for realizing indoor wireless signal coverage provided by the present invention is arranged between a terminal and a base station, and the terminal communicates with the base station through the device.

[0044] Embodiment 1

[0045] This embodiment provides a device 100 for achieving indoor wireless signal coverage, such as Figure 1 As shown, including:

[0046] The monitoring processing unit 110 monitors the base station signal and analyzes the uplink and downlink timing, and outputs the control signal 10 according to the uplink and downlink timing of the base station signal, and the control signal is used to control the radio frequency signal processing unit 120: open the uplink radio frequency link, or the downlink radio frequency link;

[0047] The control signal 10 correctly distinguishes the uplink and downlink working periods of the base station signal, opens the uplink RF link of the uplink RF signal processing unit 120 during the uplink working period of the base station signal, and opens the downlink RF link of the downlink RF signal processing unit 120 during the downlink working period of the base station signal;

[0048] The monitoring processing unit 110 generates a control signal 10 according to the uplink and downlink working sequence of the base station: during the downlink scheduling period, the control signal 10 is at a high level; during the uplink scheduling period, the control signal is at a low level;

[0049] The protocol frame structure involved in the present invention is as follows Figure 2 As shown;

[0050] When the control signal 10 is at a high level, the downlink radio frequency link is turned on and the uplink radio frequency link is turned off; when the control signal 10 is at a low level, the uplink radio frequency link is turned on and the downlink radio frequency link is turned off.

[0051] Furthermore, the monitoring processing unit 110 includes:

[0052] The main protocol parser 111 monitors the first base station signal, scans the first base station to be connected to the network, and when the first base station is connected to the network but not communicating with the base station, quickly parses the uplink and downlink timing of the first base station signal, and outputs the first control signal 11 to the selection switch 113 according to the uplink and downlink timing of the first base station signal;

[0053] The protocol analyzer 112 monitors the second base station signal, scans the second base station for access, and quickly analyzes the uplink and downlink timing of the second base station signal when the second base station is accessed but not communicating with the base station, and outputs the second control signal 12 to the selection switch 113 according to the uplink and downlink timing of the second base station signal;

[0054] The main protocol analyzer 111 is also used to output a switch selection signal 20 to the selection switch 113;

[0055] The selection switch 113 has an input end connected to the output end of the main protocol parser 111 and the slave protocol parser 112, selects the first control signal 11 or the second control signal 12 as the control signal 10 based on the switch selection signal 20, and outputs the control signal 10 to the RF signal processing unit 120 to control the opening of the RF link.

[0056] When the terminal communicates with the current base station through the main protocol parser 111 or the slave protocol parser 112, the current base station is the first base station connected to the network by the main protocol parser 111 or the second base station connected to the network by the slave protocol parser 112, and the other protocol parser scans a new base station connected to the network, such as a third base station, and generates a control signal;

[0057] When the main protocol analyzer 111 determines that it is necessary to switch to the third base station, the control signal output by the protocol analyzer connected to the third base station to be switched is selected through the switch selection signal 20.

[0058] The master protocol parser 111 and the slave protocol parser 112 transmit instructions or information through a data command interaction channel: when the master protocol parser 111 scans the current base station to be connected to the network, an instruction is sent through the data command interaction channel to notify the slave protocol parser 112 to scan the next base station to be connected to the network; the slave protocol parser 112 sends the received signal strength to the master protocol parser 111 through the data command interaction channel.

[0059] The main protocol parser 111 and the slave protocol parser 112 work together to complete the uninterrupted amplification of the radio frequency signals of different base stations, ensuring that the terminal switches smoothly from one base station to another;

[0060] Specifically, the slave protocol parser 112 monitors the base station signal, scans the second base station in the network, and sends the signal strength of the received base station signal, i.e., the second received signal strength, to the master protocol parser 111 through the data command interaction channel;

[0061] The main protocol parser 11 determines whether to perform base station switching based on the first received signal strength received by itself, the second received signal strength sent from the protocol parser, and the received signal strength switching threshold, and outputs a switch selection signal 20 to instruct the selection switch 113 to select the control signal output by the corresponding protocol parser.

[0062] Since base station signals are introduced into indoor spaces through outdoor antennas via the air interface, the base station transmit power is large, while the terminal transmit power is small. The path loss between the base station and the terminal is large, and the RF signal reaching the terminal is very small. If it is not amplified, the indoor signal will be too small, and the signal power entering the terminal will be less than the receiving sensitivity of the terminal, so that the terminal cannot receive the correct signal, resulting in uplink communication interruption.

[0063] Therefore, the present invention proposes to amplify the radio frequency signal in the channel to eliminate the path loss between the base station and the terminal, thereby ensuring that the base station and the terminal can correctly receive the signal, thereby ensuring reliable communication.

[0064] The radio frequency signal processing unit 120 amplifies the uplink radio frequency signal or the downlink radio frequency signal according to the uplink and downlink signal timing of the base station, and outputs it to the terminal;

[0065] like Figure 1 As shown, the radio frequency signal processing unit 120 includes: a downlink radio frequency link 121 composed of a first link control switch SWT1, a downlink low noise amplifier LNA1, a downlink automatic gain control unit AGC1, a downlink power amplifier PA1, and a second link control switch SWT2;

[0066] An uplink radio frequency link 122 consisting of a second link control switch SWT2, an uplink low noise amplifier LNA2, an uplink automatic gain control unit AGC2, an uplink power amplifier PA2, and a first link control switch SWT1;

[0067] The selection switch 113 outputs the control signal to the first link control switch SWT1, the second link control switch SWT2, the uplink low noise amplifier LNA2, the uplink power amplifier PA2, the downlink low noise amplifier LNA1, and the downlink power amplifier PA1;

[0068] The specific circuit connection is: the first link control switch SWT1 is connected to the input end of LNA1, the output end of LNA1 is connected to the input end of AGC1, the output end of AGC1 is connected to the input end of PA1, and the output end of PA1 is connected to the switch SWT2;

[0069] The second link control switch SWT2 is connected to the input end of LNA2, the output end of LNA2 is connected to the input end of AGC2, the output end of AGC2 is connected to the input end of PA2, and the output end of PA2 is connected to the switch SWT1;

[0070] The first link control switch SWT1 and the second link control switch SWT2 select the uplink radio frequency link 121 or the downlink radio frequency link 122 according to the control signal 10 to ensure normal communication between the base station and the terminal;

[0071] Specifically, SWT1 and SWT2 open the downlink RF link and close the uplink RF link according to the control signal 10: SWT1 connects to the input end of LNA1 and disconnects PA2, SWT2 connects to the output end of PA1 and disconnects LNA2, SWT1 transmits the RF signal transmitted by the base station received by the first antenna to LNA1, and after amplification processing by LNA1, AGC1 and PA1, it is sent to the terminal through the second antenna of the SWT2 link;

[0072] Similarly, SWT1 and SWT2 open the uplink RF link and close the downlink RF link according to the control signal 10: SWT2 is connected to the input end of LNA2 and disconnects PA1, SWT1 is connected to the output end of PA2 and disconnects LAN1, SWT2 transmits the RF signal transmitted by the terminal received by the second antenna to LNA2, and after amplification processing by LNA2, AGC2 and PA2, it is sent to the base station through the first antenna of the SWT1 link; when the control signal is at a high level, the power of LNA1 and PA1 is turned on; and the power of LNA2 and PA2 is turned off at the same time; when the control signal is at a low level, the power of LNA2 and PA2 is turned on; and the power of LNA1 and PA1 is turned off at the same time; the low noise amplifiers LNA1 and LNA2 amplify the uplink low-power RF signal or the downlink low-power RF signal entering the RF signal processing unit to ensure the information quality of the base station RF signal after amplification;

[0073] Automatic gain control units AGC1 and AGC1 control the amplification gain of the uplink and downlink radio frequency links according to the radio frequency link gain control signal 30 output by the main protocol analyzer 111 to ensure that the radio frequency signal of the base station is not distorted;

[0074] Further, the main protocol parser 111 automatically adjusts the gain of the uplink and downlink radio frequency links according to the target output power and the size of the signal input to the device to ensure that the output radio frequency signal is not distorted and the communication quality between the base station and the terminal is guaranteed;

[0075] Specifically, the main protocol analyzer 111 is connected to the uplink automatic gain control unit AGC1 and the downlink automatic gain control unit AGC2, and outputs a radio frequency link gain control signal to AGC1 or AGC2 according to the target output power;

[0076] The power amplifiers PA1 and PA2 further amplify the uplink RF signal or the downlink RF signal to eliminate the link loss between the base station and the terminal.

[0077] Embodiment 2

[0078] The device 100 for realizing indoor wireless signal coverage provided by the present invention is arranged between the terminal and the base station, and the terminal communicates with the base station through the device; the terminal can smoothly switch between the base stations through the device 100 provided by the present invention, and the signal will not be interrupted when switching between the base stations, and the signal will pass normally according to the uplink and downlink timing of the system;

[0079] The main protocol parser 111 and the slave protocol parser 112 work together to achieve uninterrupted amplification of radio frequency signals from different base stations, ensuring that the terminal switches smoothly from one base station to another.

[0080] This embodiment specifically describes how the master protocol parser 111 and the slave protocol parser 112 work together; Figure 3 As shown:

[0081] Exemplarily, the terminal communicates with the base station 1 connected to the network through the main protocol parser 111. The main protocol parser 111 outputs the first control signal 11 according to the signal of the base station 1, and the selection switch selects the first control signal 11 to control the uplink and downlink radio frequency links, and the terminal connects to the base station 1; the first control signal 11 controls the downlink radio frequency link 121 composed of SWT1, LNA1, AGC1, PA1, and SWT2 to be in a working state, and the downlink radio frequency signal of the current base station reaches the terminal;

[0082] When the downlink signal cycle of the current base station 1 is completed, the level polarity of the first control signal 11 changes from a high level to a low level. At this time, the first control signal 11 controls the closing of the downlink radio frequency link composed of SWT1, LNA1, AGC1, PA1, and SWT2, and opens the uplink radio frequency link 122 composed of SWT2, LNA2, AGC2, PA2, and SWT1, so that the radio frequency signal of the terminal can reach the current base station, ensuring that the system can work in TDD half-duplex mode;

[0083] At the same time, the master protocol parser 111 sends an instruction 40 through the data command interaction channel to notify the slave protocol parser 112 to scan the next base station in the network; the slave protocol parser scans the base station 2 in the network, and outputs the second control signal 12 according to the signal of the base station 2; at the same time, the slave protocol parser 112 sends the received signal strength 50 of the base station 2 to the master protocol parser 111 through the data command interaction channel;

[0084] The main protocol parser 11 determines whether to switch base stations according to the first received signal strength received by itself, the second received signal strength sent from the protocol parser, and the received signal strength switching threshold value. When the first received signal strength of base station 1 is lower than the received signal strength switching threshold value and the second received signal strength of base station 2 is higher than the received signal strength switching threshold value, it is determined that switching from base station 1 to base station 2 is required;

[0085] The main protocol analyzer 111 selects the selection switch of the control signal through the switch selection signal 20, so that the uplink and downlink radio frequency links in the device are controlled by the second control signal 12;

[0086] Optionally, when the switch selection signal 20 is at a high level, the selection switch 113 selects the first control signal 11, and when the switch selection signal 20 is at a low level, the selection switch 113 selects the second control signal 12;

[0087] When the uplink and downlink radio frequency links are controlled by the slave protocol parser 112, the master protocol parser 111 automatically scans the next base station 3 to enter the network, and generates the first control signal 11 again according to the uplink and downlink timing output of the base station 3 signal; at the same time, the master protocol parser 111 again compares the first received signal strength received by itself, the second received signal strength sent by the slave protocol parser 112, and the received signal strength switching threshold to determine whether to perform base station switching;

[0088] In this way, under the cooperation of the master-slave protocol parser, the above process works cyclically to ensure that the signal will not be interrupted when switching between base stations, thereby ensuring that the terminal works smoothly and uninterruptedly between different base stations.

[0089] The deployment diagram of this device when actually introducing outdoor wireless signals into indoor areas is as follows: Figure 4 As shown,

[0090] The first link control switch SWT1 is connected to the first antenna, responsible for receiving the radio frequency signal transmitted by the base station, and after amplification through the device of the present patent, it is sent to the terminal through the second antenna of the second link control switch SWT2 link;

[0091] The second link control switch SWT2 is connected to the second antenna, responsible for receiving the radio frequency signal transmitted by the terminal, and after amplifying and processing through the device of this patent, sending it to the base station through the first antenna of the first link control switch SWT1 link.
