As shown in fig. 1, the system architecture 1000 may include one or more of terminal devices 1001, 1002, 1003, a network 1004 and a server 1005. The network 1004 is used to provide a medium for communication links between the terminal devices 1001, 1002, 1003 and the server 1005.

In these fields, a wireless network control system based on 5G can be adopted, and high reliability and low time delay need to be ensured in a scene with frequent man-machine cooperation or interaction.
However, in the related art, the same transmission logic is usually used for different types of control signals, and for the control signals requiring low time-ductility, serious consequences may be caused, and the stability and safety of the system cannot be ensured.

Through the embodiment of the disclosure, positions can be distributed aiming at different types of control signals, so that the system can preferentially process the relatively urgent control signals, the stability and the safety of the system are improved, and the low time delay and the reliability of the system are further ensured.
Hereinafter, steps S210 to S230 of the signal transmission method in the present exemplary embodiment will be described in more detail with reference to the drawings and the embodiments.
Step S210, acquiring a control signal, and acquiring a signal type of the control signal;
in an example embodiment of the present disclosure, a control signal may be acquired. Specifically, the control signals, including those sent by the microprocessor to the memory and input/output device interface circuits, include: read/write signals, chip select signals, interrupt response signals, and the like; other components may also be included to feed back to the CPU, such as: interrupt application signals, reset signals, bus request signals, device ready signals, etc. For example, the control signal may be a signal received by the rnc, and the control signal may be used to indicate an action to be performed by the rnc after the rnc receives the control signal.
It should be noted that the present disclosure does not limit the specific form of the user control signal.
In an example embodiment of the present disclosure, after the control signal is obtained through the above steps, a signal type of the control signal may be acquired. In particular, the signal type of the control signal may be used to distinguish between different control signals. Wherein the control signals can be classified from multiple dimensions.
By way of example, the signal types of the control signal may include a continuous-time signal, a discrete-time signal; the signal type of the control signal may also include analog signals, digital signals, discrete signals; the signal type of the control signal may also include a periodic type signal, an event trigger type signal.
It should be noted that, the present disclosure is not limited to the specific classification of the signal type of the control signal and the specific manner of obtaining the signal type of the control signal.
In an example embodiment of the present disclosure, a periodicity of the control signal may be acquired, and a signal type of the control signal is determined according to the periodicity of the control signal. Referring to fig. 3, determining the signal type of the control signal according to the periodicity of the control signal may include the following steps S310 to S320:
step S310, acquiring the periodicity of the control signal;
in step S320, the signal type of the control signal is determined according to the periodicity of the control signal.
In an example embodiment of the present disclosure, after the control signal is obtained through the above steps, the periodicity of the control signal may be obtained, and the signal type of the control signal may be determined according to the periodicity of the control signal. The signal type of the control signal comprises a periodic type signal and an event trigger type signal. Specifically, the control signal of the periodic type signal means that the time domain characteristic of the control signal is periodic, the period of the control signal means the time interval between two identical signals, and the event trigger type signal means that the time domain characteristic of the control signal is non-periodic.
In an example embodiment of the present disclosure, the periodicity of the control signal may be obtained, and the signal type of the control signal may be determined according to the periodicity of the control signal. Specifically, the periodicity of the control signal may be determined by a period analysis method, the signal type of the control signal having the periodicity may be determined as a periodic type signal, and the signal type of the control signal having no periodicity may be determined as an event trigger type signal.
For example, zero-crossing detection, pulse shaping, etc. may be used to determine the periodicity of the control signal.
It should be noted that the present disclosure is not limited to a specific manner of obtaining the periodicity of the control signal.
Through the above steps S310 to S320, the periodicity of the control signal can be obtained, and the signal type of the control signal is determined according to the periodicity of the control signal. Through the embodiment of the disclosure, the control signal can be divided into the periodic type signal and the event trigger type signal according to the periodicity, so that the control signal is distributed according to the priority of the periodic type signal and the event trigger type signal, and the stability and the safety of the system are improved.
Step S220, acquiring time domain resources for transmitting control signals, and determining the distribution positions of the control signals in the time domain resources according to the signal types of the control signals;
in an example embodiment of the present disclosure, a time domain resource for transmitting a control signal may be acquired. Specifically, the time domain resource for transmitting the control signal refers to a resource for transmitting the control signal under the time domain definition. For example, the time domain resource may include a frame, a subframe, a slot, etc., where the length of the frame is 10ms, one frame includes 10 subframes, each subframe is 1ms, and each subframe includes 2 slots.
It should be noted that, the present disclosure is not limited to a specific type of time domain resource for transmitting the control signal.
In an example embodiment of the present disclosure, after the signal type of the control signal and the time domain resource in which the control signal is transmitted are obtained through the above steps, the allocation position of the control signal in the time domain resource may be determined according to the signal type of the control signal. Specifically, different control signal allocation methods may be determined according to different signal types, and allocation positions of the control signals in the time domain resources may be determined according to the different control signal allocation methods.
For example, the signal type of the control signal includes a periodic type signal and an event trigger type signal, where the event trigger type signal has a higher processing priority, and the periodic type signal has a lower processing priority, and when the control signal whose signal type is the event trigger type signal is received, the control signal may be allocated to a position in the time domain resource that is farther forward, and when the control signal whose signal type is the periodic type signal is received, the control signal may be allocated to a position in the time domain resource that is farther backward, so as to preferentially process the control signal whose signal type is the event trigger type signal.
It should be noted that, the present disclosure does not make any particular limitation on the specific manner of determining the allocation position of the control signal in the time domain resource according to the signal type of the control signal.
In an example embodiment of the present disclosure, when the signal type of the control signal is a periodic type signal, the control signal may be uniformly allocated in the time domain resource to determine an allocation position of the control signal in the time domain resource. Specifically, when the signal type of the received control signal is a periodic type signal, it may be indicated that the processing priority of the control signal is low, and therefore the control signal may be uniformly distributed in the time domain resource.
For example, the time domain resource has 11 air interface resource locations, the control signal may be allocated to a sixth air interface resource location, the next control signal (periodic type signal) is allocated to a third air interface resource location, the next control signal (periodic type signal) is allocated to a ninth air interface resource location, and so on, to implement uniform allocation of the control signal, where the air interface resource location refers to a resource location that is not occupied in the resource locations, or a resource location that is not occupied in the time domain resource.
It should be noted that, the present disclosure is not limited specifically to the specific manner of uniformly distributing the control signals in the time domain resources.
In an example embodiment of the present disclosure, the control signals may be uniformly allocated to the time domain resources according to a distance product maximization principle. The distance product maximization principle is that, when the first two control signals are received, the first two control signals are respectively allocated to a first resource position and a last resource position of the time domain resource, when the control signals are received again, the control signals are allocated to a target resource position, and the product of the number of air interface resource positions before the target resource position and the number of air interface resource positions after the target resource position is maximized.
Specifically, the empty resource location refers to a resource location having multiple resource locations in the time domain resource, and an unoccupied resource location in the resource locations, or an unoccupied resource location in the resource locations.
For example, the time domain resource has 12 air interface resource locations, and a first control signal may be allocated to a first air interface resource location (a first air interface resource location), a second received control signal may be allocated to a last air interface resource location (a twelfth air interface resource location), and a third received control signal may be allocated to a sixth air interface resource location, where the sixth air interface resource location is preceded by 4 air interface resource locations (a second air interface resource location, a third air interface resource location, a fourth air interface resource location, and a fifth air interface resource location), and the sixth air interface resource location is followed by 5 air interface resource locations (a seventh air interface resource location, an eighth air interface resource location, a ninth air interface resource location, a tenth air interface resource location, and an eleventh air interface resource location), that is, the number of air interface resource locations before the sixth air interface resource location is 4, the number of air interface resource locations after the sixth air interface resource location is 5, the product of the number of air interface resource locations before the sixth air interface resource location and the number of air interface resource locations after the sixth air interface resource location is 20, that is, the product is the largest when a control signal is allocated to the sixth air interface resource location, the control signal can be allocated to the ninth air interface resource location when the next control signal is received, 2 air interface resource locations (the seventh air interface resource location, the eighth air interface resource location) are before the ninth air interface resource location, 2 air interface resource locations (the tenth air interface resource location, the eleventh air interface resource location) are after the ninth air interface resource location, that is, the number of air interface locations before the ninth air interface resource location is 2, the number of air interface resource positions after the ninth air interface resource position is 2, and the product of the number of air interface resource positions before the ninth air interface resource position and the number of air interface resource positions after the ninth air interface resource position is 4, that is, when a control signal is allocated to the ninth air interface resource position, the product is the largest, and so on, the allocation of the control signal is realized, that is, the principle of the largest distance product described in this embodiment.
Through the embodiment of the disclosure, the control signals can be uniformly distributed in the time domain resource to determine the distribution position of the control signals in the time domain resource, so that the stability and the safety of the system can be improved, and the low time delay and the reliability of the system can be further ensured.
In an example embodiment of the present disclosure, when the signal type of the control signal is an event trigger type signal, the control signal may be allocated in the time domain resource on a near basis to determine an allocation position of the control signal in the time domain resource. The near-term is that a plurality of resource positions in the time domain resource have a signal processing sequence, and the control signal is allocated to the air interface resource position which is processed firstly under the condition that the signal processing sequence of the allocated control signal in the current time domain resource is not influenced.
For example, the time domain resource has 5 resource locations (a first resource location, a second resource location, a third resource location, a fourth resource location, and a fifth resource location, wherein the processing order of the resource locations is the first resource location, the second resource location, the third resource location, the fourth resource location, and the fifth resource location), wherein the first resource location, the second resource location, and the fifth resource location are occupied resource locations, and the third resource location and the fourth resource location are empty resource locations, at this time, the control signal may be allocated to the third resource location, so as to realize allocating the control signal according to the principle of proximity.
It should be noted that, the present disclosure is not limited specifically to the specific manner of allocating the control signal in the time domain resource according to the proximity principle.
Through the embodiment of the disclosure, the control signals with the signal types as the event triggering types can be distributed at the positions closer to the front, so that the control signals are processed preferentially, and the stability and the safety of the system are improved.
In an example embodiment of the present disclosure, candidate allocation positions of a control signal in a time domain resource may be determined according to a signal type of the control signal, a remaining allocation space of the candidate allocation positions may be obtained, and when the remaining allocation space of the candidate allocation positions is greater than or equal to a signal size of the control signal, the candidate allocation positions may be determined as the allocation positions of the control signal in the time domain resource. Referring to fig. 4, when the remaining allocation space of the candidate allocation location is greater than or equal to the signal size of the control signal, determining the candidate allocation location as the allocation location of the control signal in the time domain resource may include the following steps S410 to S420:
step S410, determining candidate allocation positions of the control signals in the time domain resources according to the signal types of the control signals, and acquiring residual allocation spaces of the candidate allocation positions;
in an example embodiment of the present disclosure, after determining the signal type of the control signal, the candidate allocation position of the control signal in the time domain resource may be determined according to the signal type of the control signal. Specifically, the candidate allocation positions of the control signals in the time domain resources may be determined according to the manner provided by the embodiments of the present disclosure.
In an example embodiment of the present disclosure, a remaining allocation space of the candidate allocation location may be obtained. Specifically, the allocation positions may correspond to frames, subframes, time slots, and the like, and in each allocation position, control signals of different sizes may be borne, that is, the allocation position has allocation control, and after the candidate allocation position is determined according to the above steps, the remaining allocation space of the candidate allocation position may be obtained.
For example, a frame is 10ms in length, a frame includes 10 subframes, each subframe is 1ms, each subframe includes 2 slots, and each slot can store 7 symbols, so that for one allocation location (the allocation space of the allocation location is one slot), 7 symbols can be stored, and if the allocation location already stores 2 symbols, the remaining allocation space of the allocation location is 5 symbols.
It should be noted that, the present disclosure does not specifically limit the specific manner of obtaining the remaining allocation space of the candidate allocation location.
In step S420, when the remaining allocation space of the candidate allocation positions is greater than or equal to the signal size of the control signal, the candidate allocation positions are determined as the allocation positions of the control signal in the time domain resource.
In an example embodiment of the present disclosure, after determining the remaining allocation space of the candidate allocation location through the above steps, the magnitude relationship between the remaining allocation space of the candidate allocation location and the signal size of the control signal may be determined, and when the remaining allocation space of the candidate allocation location is greater than or equal to the signal size of the control signal, the candidate allocation location is determined as the allocation location of the control signal in the time domain resource. Specifically, the remaining allocation space of the candidate allocation location is greater than or equal to the signal size of the control signal, which indicates that the candidate allocation location can be used for carrying the control signal, and therefore, the candidate control signal can be determined as an allocation bit of the control signal in the time domain resource, and further, if the remaining allocation space of the candidate allocation location is smaller than the signal size of the control signal, other allocation locations in the time domain resource need to be selected as allocation locations for carrying the control signal.
Through the above steps S410 to S420, the candidate allocation positions of the control signal in the time domain resource may be determined according to the signal type of the control signal, the remaining allocation space of the candidate allocation positions may be obtained, and when the remaining allocation space of the candidate allocation positions is greater than or equal to the signal size of the control signal, the candidate allocation positions may be determined as the allocation positions of the control signal in the time domain resource.

Specifically, the control signals may be allocated according to allocation positions of the control signals in the time domain resource, and transmitted in an allocated order, so that a subsequent system receives the control signals and then processes the control signals according to a receiving order.
It should be noted that, the present disclosure does not specifically limit the specific manner of transmitting the control signal according to the allocated position of the control signal in the time domain resource.

step S510, sending the distribution position of the control signal in the time domain resource to the terminal equipment;
step S520, the terminal device transmits the control signal according to the allocated position of the control signal in the time domain resource.

Specifically, when the terminal device needs to send the control signal, the type of the control signal may be sent to a scheduling terminal device or a server executing the scheme, the scheduling terminal device or the server determines the allocation position of the control signal in the time domain resource, and the scheduling terminal device or the server sends the scheduling result to the terminal device.
