Referring to fig. 1, fig. 1 is a schematic structural diagram of a mold testing system according to an embodiment of the present disclosure. The module testing system can include, but is not limited to, one or more module testing receiving terminals and one or more module testing transmitting terminals, for example, fig. 1 takes a module testing receiving terminal 1, a module testing receiving terminal 2, a module testing receiving terminal 3, a module testing receiving terminal 4, a module testing transmitting terminal 5 and a central control software as an example, wherein the module testing transmitting terminal 5 can establish a wireless link with the module testing receiving terminal 1 for communication, the module testing transmitting terminal 5 can also establish a wireless link with the module testing receiving terminal 2 for communication, the module testing transmitting terminal 5 can also establish a wireless link with the module testing receiving terminal 3 for communication, and the module testing transmitting terminal 5 can also establish a wireless link with the module testing receiving terminal 4 for communication. The central control software is responsible for collecting the information of the test terminals of different test points (for example, collecting the measurement information of different test receiving terminals and the configuration information transmitted by the test sending terminal), and the central control software intelligently analyzes the collected information to obtain an analysis result and outputs a network specification and network optimization suggestion according to the analysis result. The analog testing system shown in fig. 1 includes, but is not limited to, an analog testing receiving terminal, a central control software, and an analog testing transmitting terminal, and may further include other communication devices, and the number and form of the devices shown in fig. 1 are for example and do not constitute a limitation to the embodiments of the present application.

In the embodiment of the application, the analog testing transmitting terminal represents a site to be selected of the network specification and network optimization, provides a signal source required by analog testing for the analog testing system, and is the core of the whole analog testing system. The module test sending terminal needs to have the characteristic of portability and can be realized by the terminal equipment of the existing communication system. A modular measurement transmitting terminal may refer to various forms of User Equipment (UE), an access terminal, a subscriber unit, a subscriber Station, a Mobile Station (MS), a remote Station, a remote terminal, a Mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment.

In an alternative embodiment, the morphological structure of the modular test sending terminal is as shown in fig. 2, and as shown in fig. 2, the modular test sending terminal may be composed of a smart terminal and a mushroom antenna. The intelligent terminal can use an internet of things chip platform (such as a Chunreng UIS8910DM), and the internet of things chip platform is connected with the remote mushroom antenna through a radio frequency cable. The relevant parameters of the modular test receiving terminal are configured by means of an AT (instruction set) instruction set.

In the embodiment of the application, the modular measurement receiving terminal can sweep the existing network signal and can also scan the signal of the analog sending terminal equipment to provide the measurement information of the covered area. In addition, the modular test receiving terminal also has the characteristic of being portable, and can be terminal equipment similar to the modular test sending terminal, and the description is omitted here. For example, the modular test receiving terminal is in a conventional terminal device form, and an internet of things chip platform (such as a chunsy UIS8910DM) can be directly used.

In an alternative embodiment, a deployment scenario of the module testing system shown in fig. 1 may be as shown in fig. 3a, where the module testing sending terminal and the module testing receiving terminal need to synchronize to an existing network cell, and the module testing sending terminal 5 synchronizes to the existing network cell and specifies to send a cell signal, or synchronizes to a specified module testing cell and specifies to send a cell signal. The module measurement receiving terminal 1, the module measurement receiving terminal 2, the module measurement receiving terminal 3 and the module measurement receiving terminal 4 are synchronized to the current network cell or the appointed module measurement cell, and the current network cell and the appointed cell are measured.

In another alternative embodiment, the deployment scenario of the analog measurement system shown in fig. 1 may be as shown in fig. 3b, where the analog measurement terminal performs "independent networking", and the analog measurement sending terminal 5 is in a coverage loss state, and works as an orphan station to directly send the common signal and the system information to the designated cell. If a plurality of module testing transmitting terminals exist in the module testing system, the module testing transmitting terminal #1 which is started up firstly is in a loss coverage state, and the module testing transmitting terminal # 2 and the module testing transmitting terminal N which are started up subsequently are synchronized to the module testing transmitting terminal #1 according to a starting-up network searching result or work as an isolated station. And the module measurement receiving terminal 1, the module measurement receiving terminal 2, the module measurement receiving terminal 3 and the module measurement receiving terminal 4 measure the cells according to the system information and the monitoring cell list.

In an optional embodiment, after the module testing system shown in fig. 1 is deployed according to the deployment scenario shown in fig. 3a or fig. 3b, the module testing transmitting terminal 5 periodically and cyclically transmits a common signal to the module testing receiving terminal 1, the module testing receiving terminal 2, the module testing receiving terminal 3, and the module testing receiving terminal 4, the module testing receiving terminal 1 completes the residence of the serving cell or periodically measures and reports the serving cell and the neighboring cell according to the received common signal, the module testing receiving terminal 2 completes the residence of the serving cell or periodically measures and reports the serving cell and the neighboring cell according to the received common signal, the module testing receiving terminal 3 completes the residence of the serving cell or periodically measures and reports the serving cell and the neighboring cell according to the received common signal, and the module testing receiving terminal 4 completes the residence of the serving cell or periodically measures and reports the serving cell according to the received common signal, And the adjacent cell carries out periodic measurement and report. Since the modular test transmitting terminal 5 circularly transmits a plurality of signals for a long time, the power consumption of the modular test transmitting terminal 5 is inevitably increased, and the endurance time of the modular test transmitting terminal 5 is influenced.

The application provides a signal transmission method which can be applied to a mode measurement system shown in fig. 1. When the module test receiving terminal is not required to measure the adjacent cell, the module test transmitting terminal 5 does not transmit System Information Block (SIB) of the serving cell to the module test receiving terminal, and informs the module test receiving terminal of normally residing in the cell through a Master Information Block (MIB) carrying message, and the module test receiving terminal measures the signal of the module test transmitting terminal by using a preset paging cycle. The power consumption of the modular measurement sending terminal is reduced, and the endurance time of the modular measurement sending terminal in the network specification and network optimization is prolonged.

Referring to fig. 4, fig. 4 is a schematic flowchart of a signal transmission method according to an embodiment of the present disclosure, where the signal transmission method is applicable to the analog testing system shown in fig. 4, and the signal transmission method is described from the perspective of interaction between an analog testing receiving terminal and an analog testing transmitting terminal. The signal transmission method comprises the following steps:

s401, the module testing sending terminal determines the current module testing scene requirement.

The model measurement scene requirement can be measuring a service cell, periodically measuring the service cell and reporting a measurement result; the requirement of the model measurement scenario can also be to measure a serving cell and an adjacent cell, periodically measure the serving cell and the adjacent cell, and report the measurement result. The adjacent cell can be a same-frequency adjacent cell of the serving cell, can also be a different-frequency adjacent cell of the serving cell, and can also be a same-frequency adjacent cell and a different-frequency adjacent cell of the serving cell.

S402, the module measurement sending terminal sends a first downlink public signal according to the requirement of a module measurement scene; correspondingly, the modular measuring receiving terminal receives the first downlink common signal.

And the reserved field in the MIB in the first downlink common signal is used for indicating whether the system information of the serving cell is included in the first downlink common signal. That is to say, according to the requirements of the model measurement scene, the sending of signals which are not necessary for the resident cell can be reduced, and the endurance time of the network-based excellent model measurement sending terminal can be prolonged.

In an optional embodiment, when the requirement of the measurement scenario is to measure a serving cell, a reserved field in the MIB in the first downlink common signal indicates that system information of the serving cell is not included in the first downlink common signal. It may be that the system information of the serving cell is not included in the first downlink common signal when the reserved field in the MIB indicates the first value. The system information of the serving cell may include SIB1-SIB5, among others. When the neighbor cell does not need to be measured, the frequency point information, the cell list information and the like in the system information of the serving cell are not needed, so that the system information of the serving cell does not need to be sent. When the reserved field in the MIB in the first downlink common Signal indicates that the system information of the serving Cell is not included in the first downlink common Signal, a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Cell Reference Signal (CRS), and the MIB may be included in the first downlink common Signal. As shown in fig. 5, the MIB includes a downlink Bandwidth (dl-Link Bandwidth), a Physical Hybrid ARQ Indicator Channel (PHICH) configuration parameter (phy-configuration), a System Frame Number (SFN), scheduling information of the SIB1, and a reserved field (spare). For example, the spare has 5 bits, and the 5 bits in the spare are all 1, that is, 11111, at this time, the first value indicated by the spare is 31, and the first value 31 indicates that the first downlink common signal does not include the system information of the serving cell, that is, when the spare in the MIB is set to be the first value 31, the first downlink common signal sent by the modular measurement sending terminal does not include SIB1-SIB 5.

In another optional embodiment, when the requirement of the measurement scenario is to measure the serving cell and the neighbor cell, a reserved field in the MIB in the first downlink common signal indicates that the system information of the serving cell is included in the first downlink common signal. It may be that the system information of the serving cell is included in the first downlink common signal when the reserved field in the MIB indicates the second value. At this time, the PSS, SSS, CRS, MIB, and SIB1-SIB5 may be included in the first downlink common signal. For example, the spare has 5 bits, and the 5 bits in the spare are all made to be 0, that is, 00000, at this time, the second value indicated by the spare is 0, and the second value 0 indicates that the first downlink common signal includes the system information of the serving cell, that is, when the spare in the MIB is set to be the second value 0, the first downlink common signal transmitted by the modular test transmitting terminal includes SIB1-SIB 5.

In an optional implementation manner, the modulo measurement transmitting terminal sets the transmission period of the CRS and the MIB in the first downlink common signal to 20ms, and transmits the CRS and the MIB only in the subframe #0 of the radio frame satisfying SFN mod 2 ═ 0. That is to say, the transmission cycle of the CRS and the MIB is increased by the modular measurement transmitting terminal, and retransmission transmission is not performed when the CRS and the MIB are transmitted in the transmission cycle of the CRS and the MIB, so that the frequency of transmitting the CRS and the MIB can be reduced within a certain time, and the data transmission amount of the modular measurement transmitting terminal is reduced, thereby reducing the working time of the modular measurement transmitting terminal, reducing the power consumption of the modular measurement transmitting terminal, and improving the endurance time of the modular measurement transmitting terminal in the network specification and network optimization.

In an optional embodiment, when the requirement of the measurement scenario is to measure the serving cell and the neighboring cell, the SIB1 is transmitted once in a transmission period of the SIB1 in the system information of the serving cell, where the transmission period may also be a scheduling period. That is, when the measurement of the serving cell and the neighbor cell by the measurement-modeled receiving terminal is required, the measurement-modeled transmitting terminal does not perform retransmission transmission when transmitting SIB1 in the transmission period of SIB1, that is, SIB1 is transmitted only in subframe #5 of the radio frame satisfying SFN mod8 equal to 0. The number of times of sending the SIB1 can be reduced, and the data sending amount of the analog testing sending terminal is reduced, so that the working time of the analog testing sending terminal is reduced, the power consumption of the analog testing sending terminal can be reduced, and the endurance time of the analog testing sending terminal in the network specification and network quality is prolonged.

In an alternative embodiment, when the requirement of the mode measurement scenario is to measure the serving cell and the neighboring cells, the mode measurement transmitting terminal sets a transmission period of SIB2-SIB5 in the System Information of the serving cell to 80ms, that is, sets a System Information Window (SI-Window) to 80 ms. Each SIB is contained in only one System Information (SI), each SI is associated with one SI-window, and the SI-windows of different SIs do not overlap with each other, that is, SIB2-SIB5 may be transmitted within the SI-window. The length of the SI-window is the same for all SI and is configurable. Therefore, the length of the SI-window can be set to 80ms, i.e. the scheduling periods of SIB2-SIB5 are all 80 ms. In addition, the SIB2-SIB5 are transmitted once in the transmission period of SIB2-SIB5, that is, the SIB2-SIB5 is transmitted only once in subframe #0 of the first radio frame in the SI-window, that is, the SIB2-SIB5 is not retransmitted in the SI-window. The number of times of sending SIB2-SIB5 can be reduced, and the data sending amount of the analog testing sending terminal can be reduced, so that the working time of the analog testing sending terminal is reduced, the power consumption of the analog testing sending terminal can be reduced, and the endurance time of the analog testing sending terminal in the network specification and network optimization is prolonged.

In an optional implementation manner, the modular test receiving terminal determines whether the first downlink common signal includes the system information of the serving cell according to a reserved field in the MIB in the first downlink common signal. After receiving the MIB, the modular test receiving terminal may analyze the MIB to obtain parameter information in the MIB, and at this time, the modular test receiving terminal may obtain a value indicated by a spare in the MIB, and determine whether to receive SIB1-SIB5 according to the value indicated by the spare, that is, determine whether the first downlink common signal includes system information of a serving cell according to the value indicated by the spare. It may be negotiated in advance that the SIB1-SIB5 is not included in the first downlink common signal when the value indicated by the spare in the MIB is the first value, that the SIB1-SIB5 is included in the first downlink common signal when the value indicated by the spare in the MIB is the second value, or that the SIB1-SIB5 is included in the first downlink common signal when the value indicated by the spare in the MIB is not the first value. Therefore, after the module measurement receiving terminal receives the MIB, the information in the MIB is analyzed, the value indicated by the spare is obtained, when the spare indicates the first value, the first downlink common signal is determined not to include the system information of the service cell, when the spare indicates the second value, the first downlink common signal is determined to include the system information of the service cell, or when the spare does not indicate the first value, the first downlink common signal is determined to include the system information of the service cell. Accordingly, the modular measurement receiving terminal may determine whether system information of the serving cell is included in the first downlink common signal according to the value indicated in the spare, that is, the modular measurement receiving terminal may determine whether to receive the SIB1-SIB5 according to the value indicated in the spare. For example, it may be pre-negotiated that when the spare indicates that the first value is 31, the modular measurement receiving terminal determines that the system information of the serving cell is not included in the first downlink common signal, that is, the modular measurement receiving terminal does not receive SIB1-SIB5 when determining that the spare indicates 31, and when the spare indicates that the second value is 0, the modular measurement receiving terminal determines that the system information of the serving cell is included in the first downlink common signal, that is, the modular measurement receiving terminal receives SIB1-SIB5 when determining that the spare indicates 0.

In an alternative embodiment, when the modular measurement receiving terminal indicates the first value according to the spare in the MIB, it is determined not to receive the SIB1-SIB5, that is, the modular measurement receiving terminal determines that the first downlink common signal does not include the system information of the serving cell. At this time, the module measurement receiving terminal directly resides in the service cell and enters an idle mode, and periodically measures the service cell according to a preset paging cycle and reports a measurement result. During measurement, in order to ensure that a measurement result with higher accuracy is obtained, the number of measurement times in a certain time is as large as possible, but the power consumption is higher as the number of measurement times is larger, so that a more compromised preset paging cycle can be selected in order to take the measurement accuracy and the power consumption into consideration, that is, the preset paging cycle can be set to 640 ms.

In an optional implementation manner, when the mode-measurement receiving terminal indicates the second value according to the spare in the MIB, the mode-measurement receiving terminal determines to receive the SIB1-SIB5, that is, the mode-measurement receiving terminal determines that the first downlink common signal includes the system information of the serving cell. At this time, after receiving the MIB, the modus ponens receiving terminal receives SIB1 according to the transmission period of SIB1, then the modus ponens receiving terminal obtains the scheduling information of SIB2-SIB5 by analyzing SIB1, and the modus ponens receiving terminal receives SIB2-SIB5 according to the scheduling information of SIB2-SIB5, thereby completing cell residence. Then, the module measurement receiving terminal acquires the same-frequency adjacent cell information and different-frequency adjacent cell information of the service cell, enters an idle mode, determines a paging cycle according to the SIB2, periodically measures the service cell and the adjacent cell according to the paging cycle, and reports the measurement result. During measurement, in order to ensure that a measurement result with higher accuracy is obtained, the number of measurement times in a certain time is as large as possible, but if the number of measurement times is larger, the power consumption is higher, so that in order to take the measurement accuracy and the power consumption into consideration, a more compromised paging cycle can be selected, that is, the paging cycle can be set to 640 ms.

When the signal transmission method shown in fig. 4 is applied to the analog testing system, the flow of sending the first downlink common signal by the analog testing sending terminal can be seen in fig. 6. As shown in fig. 6, the step of sending the first downlink common signal by the modular test sending terminal may include the following steps S601-S606:

As shown in fig. 7, the modular test receiving terminal may include the following steps S701 to S710 when receiving the first downlink common signal:

and S701, receiving the PSS/SSS to complete cell synchronization.
