     DESCRIPTION OF EMBODIMENTS 
     Technical solutions in embodiments of the present application will be clearly and comprehensively described hereunder in conjunction with the accompanying figures of the embodiments of the present application. It is obvious that the described embodiments are merely a part of the embodiments of the present application, rather than all embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without the premise of paying any creative effort should fall into the protection scope of the present application. 
     With the development of communication technologies, a variety of services have been introduced in a 5G (NR, new radio) system, such as both a URLLC (Ultra-reliable low latency communication) service and an eMBB (Enhanced Mobile Broadband) service. However, for different services, signal transmission characteristics thereof are distinct. Taking the URLLC service and the eMBB service as an example, the URLLC service is characterized by achieving ultra-high reliability (e.g., 99.999%) transmission within a short delay (e.g., 1 ms), and the eMBB service is characterized by being insensitivity to delay but with possibly a large number of transmissions. 
     However, the inventor has found, in research on a scenario within which multiple services coexist, that occurrence of occupancy of a signal transmission resource might cause a service conflict when multiple services coexist. For example, for both the URLLC service and the eMBB service, in order to achieve URLLC instantaneous transmission, there will be a conflict between URLLC and eMBB, that is, the URLLC occupies a signal transmission resource that has been allocated to the eMBB, which in turn will cause a conflict between URLLC and eMBB transmission to incur mutual interference therebetween, thereby impacting demodulation performances of URLLC and eMBB. 
     Therefore, the inventor proposes the signal transmission method and apparatus, the mobile terminal and the storage medium in the present application. With the manner provided in the present application, it is achieved that, after the first time-frequency resource of the first service signal to be transmitted is acquired, the starting position and/or the ending position at which the transmission of the first service signal is interrupted in the first time-frequency resource can be further determined according to the received resource indication information, thereby achieving that usage efficiency of signal transmission resources is improved as much as possible on the premise that signal transmission can be stably performed. 
     An introduction will first be made hereunder with regard to an application environment involved in a signal transmission method provide in the present application. 
     As shown in  FIG. 1 , the application scenario involved includes a mobile terminal  100 , a mobile terminal  200 , and a base station  300 . Among them, when the mobile terminal  100  is about to perform a service signal transmission with the base station  300 , the base station may transmit transmission configuration information which is configured corresponding to the service signal to be transmitted, and then the mobile terminal  100  may acquire, from the transmission configuration information, a time-frequency resource allocated to the service signal. In one situation, the mobile terminal  200  may also apply for a service signal transmission with the base station  300  when the mobile terminal  100  is about to transmit or is transmitting a service signal. Similarly, the base station  300  may also transmit transmission configuration information of the service signal to be transmitted by the mobile terminal  200  to the mobile terminal  200 , and then the mobile terminal  200  determines a time-frequency resource allocated to the service signal to be transmitted by the mobile terminal  200  with the base station  300 . 
     After the mobile terminal  200  determines the time-frequency resource of the service signal to be transmitted, the base station  300  may generate resource indication information based on the time-frequency resource, and transmit the resource indication information to the mobile terminal  100 , so that the mobile terminal  100  may determine, according to the received transmission configuration information and the resource indication information, a starting position and/or an ending position at which the transmission of the first service signal is interrupted in the first time-frequency resource, so that usage efficiency of signal transmission resources is improved as much as possible on the premise that signal transmission can be stably performed. 
     It should be noted that the aforementioned environment is an exemplary scenario in which the number of mobile terminals and base stations may not be limited to the number shown in the figure, and in which mutual communication between mobile terminals may also not be limited to being performed via the base station, instead two or more mobile terminals may also directly communicate with each other. 
     Main technical content involved in the embodiments of the present application will be illustrated hereunder. 
     URLLC (Ultra-reliable low latency communication): an abbreviation for ultra-reliable low latency communication, which is characterized by high reliability, low delay, and extremely high availability. 
     eMBB (Enhanced Mobile Broadband): an abbreviation for enhanced mobile broadband, which refers to further improvements of performances such as user experience on the basis of the existing mobile broadband service scenario, mainly in pursuit of the ultimate communication experience among people. As its name implies, the eMMB is a technology dedicated to serving mobile devices such as mobile phones. 
     PUSCH (Physical Uplink Shared Channel): an abbreviation for physical uplink shared channel, which is used to transfer uplink data in addition to control information. Generally, it is medially located in a frequency band and occupies a vast majority of resources. 
     PUCCH (Physical Uplink Control Channel): an abbreviation for physical uplink control channel, which is mainly used to transfer control information upward. Generally, it is located at both ends of a frequency band and occupies a minority of resources. 
     Time-frequency resource: a time-frequency resource may be interpreted as a frequency band required to be used for transmitting a service signal within a certain slot. That is to say, in respect of a time-frequency resource, it has a two-dimensional characteristic in both a time domain dimension and a frequency domain dimension. With reference to  FIG. 2 , when a mobile terminal needs to perform a service transmission, a time-frequency resource allocated by a base station in a time domain is a slot k, and in a frequency domain is a frequency band from a physical resource block j to a physical resource block i. In other words, for the mobile terminal, the time-frequency resource allocated by the base station is the shaded part in  FIG. 2 . 
     Hereinafter, various embodiments of the present application will be described in detail in conjunction with the accompanying figures. 
     Reference may be made to  FIG. 3 , where the present application provides a signal transmission method applied to a mobile terminal, including: 
     S 110 : acquiring transmission configuration information of a first service signal, where the transmission configuration information includes a first time-frequency resource allocated to the first service signal. 
     It should be noted that the first service signal may be interpreted as a service signal to be transmitted by a mobile terminal. In a base station-based service transmission mode, before performing a service transmission, the mobile terminal needs to apply to a base station for a signal transmission resource required for signal transmission. Correspondingly, after receiving a request indicating that the mobile terminal desires to transmit the first service signal, the base station may determine transmission configuration information including a time-frequency resource allocated to the first service signal. Among them, the time-frequency resource for the first service signal can be determined according to the first service signal. As shown in the foregoing content, the time-frequency resource may be interpreted as a frequency band required to be used for transmitting a service signal within a certain slot, then the first time-frequency resource here may be interpreted as a signal transmission resource, allocated by the base station to the first service signal, required for signal transmission. 
     In another mode, the mobile terminal may perform a service signal transmission without resorting to the base station. For example, in a sidelink scenario, the mobile terminal may perform a service signal transmission directly with a further terminal device. In cellular Internet of Things technologies, there is also an important branch, known as Device to Device Communication (device to device communication technology), and a scenario applicable to the device to device communication technology may be interpreted as a sidelink scenario. In this mode, the first service signal may still be interpreted as a service signal to be transmitted by the mobile terminal, and transmission configuration information including a time-frequency resource allocated to the first service signal can be determined by the mobile terminal itself, or can be determined by a further communication terminal that performs transmission of the first service signal with the mobile terminal. As shown in  FIG. 4 , the service signal transmission between the mobile terminal  100  and a mobile terminal  400  involved in  FIG. 4  may be interpreted as a service signal transmission in the sidelink scenario. 
     In yet another mode, the mobile terminal may perform wireless communications with a further terminal by means of an intermediate network device. Exemplarily, the intermediate network device may be a device such as a gateway. Then in this situation, transmission configuration information including a time-frequency resource allocated to the first service signal can be determined by the intermediate network device, and further a first time-frequency resource of the first service signal to be transmitted by the mobile terminal is determined according to the transmission configuration information. 
     It should be noted that the first time-frequency resources determined in the foregoing various modes are similar in nature, that is, each of them may be interpreted as a frequency band required to be used for transmitting a service signal within a certain slot. The difference lies in that: in the mode where the first service signal transmission is performed based on the base station, the determined first time-frequency resource is a time-frequency resource required for the first service signal transmission between the mobile terminal and the base station; in the mode where mobile terminals directly communicate with each other, the determined first time-frequency resource is a time-frequency resource required for the first service signal transmission between the mobile terminals; and in the mode where the mobile terminal may perform wireless communications with a further terminal by means of an intermediate network device, the determined first time-frequency resource is a time-frequency resource required for the first service signal transmission between the mobile terminal and the intermediate network device. 
     In the present embodiment, in addition to the first time-frequency resource, the transmission configuration information may also include at least one of: a service priority, a service type, and a channel type. In an implementation, the transmission configuration information may also simultaneously include a service priority, a service type, and a channel type. 
     S 120 : receiving resource indication information, where the resource indication information is used to indicate a second time-frequency resource in which transmission of a second service signal exists. 
     It should be noted that, during a service signal transmission progress, the mobile terminal needs a signal transmission resource such as a frequency band to carry the transmitted service signal. Different mobile terminals or different services may require different signal transmission resources. Then, in order that it may be convenient for the mobile terminal to timely determine which signal transmission resources are currently occupied, a peer side in communication with the mobile terminal may generate resource indication information and transmit the generated resource indication information to the mobile terminal. 
     As a manner, in the mode where the mobile terminal performs a service signal transmission through the base station, multiple mobile terminals may access the same base station, then the base station may configure different time-frequency resources respectively for the multiple mobile terminals. Further, the base station may synchronize, in the form of resource indication information, the time-frequency resources configured for different mobile terminals to a mobile terminal currently accessing the base station. Among them, the time-frequency resources allocated by the base station to the different mobile terminals may be interpreted as time-frequency resources allocated by the base station to service signals required to be transmitted by the different mobile terminals. Then, after the mobile terminal accessing the base station receives the resource indication information, occupancy of a signal transmission resource of the base station currently being accessed can be determined from the resource indication information. For example, a second time-frequency resource indicating that transmission of a second service signal exists may be acquired. It should be noted that, in an implementation, the time-frequency resource allocated to the second service signal is greater than or equal to the second time-frequency resource. 
     As another manner, in addition to being transmitted by different mobile terminals respectively, the aforementioned first service signal and second service signal may also be transmitted by a same mobile terminal. That is, it is understandable that the first service signal and the second service signal may be initiated by different mobile terminals respectively, or may be initiated by a same mobile terminal. 
     Similarly, in the mode where multiple mobile terminals directly perform a service signal transmission with each other, resource indication information may be generated by a terminal device other than the mobile terminal that executes the signal transmission method provided in the embodiment of the present application, and the generated resource indication information is transmitted to the mobile terminal that executes the signal transmission method provided in the embodiment of the present application. In the mode where the mobile terminal performs a service signal transmission through an intermediate network device, resource indication information may be generated by the intermediate network device and synchronized to a mobile terminal that currently has an established connection with the intermediate network device. 
     S 130 : if it is determined, according to the transmission configuration information and the resource indication information, to interrupt transmission of the first service signal in the first time-frequency resource, determining a starting position and/or an ending position at which the transmission of the first service signal is interrupted. 
     It is understandable that after receiving the resource indication information, the mobile terminal may learn, through the resource indication information, occupancy of a current signal transmission resource and which services specifically occupy the signal transmission resource, and then decide whether there is a conflict between a time-frequency resource of a further service signal and the time-frequency resource of the first service signal transmitted by the mobile station itself. As a manner, whether to interrupt transmission of the first service signal in the first time-frequency resource can be determined according to the transmission configuration information and the resource indication information. 
     If a conflict is detected, a starting position and/or an ending position at which the transmission of the first service signal is interrupted in the first time-frequency resource can further be determined. 
     Exemplarily, reference may be made to  FIG. 5 - FIG. 7 , where a variety of signal interruption modes are shown respectively. 
     As shown in  FIG. 5 , in the mode shown in  FIG. 5 , a resource conflict between a time-frequency resource  20  of a further service signal and a time-frequency resource  10  of the first service signal starts at the beginning of the transmission of the first service signal (that is, a timing t 1  in the figure), and the conflict ends at a timing before an original ending position of the first service signal (that is, a timing t 2  in the figure). Among them, the ending position may be interpreted as a temporal position at which the transmission of the first service signal represented in the first time-frequency resource of the first service signal is originally ended. In this situation, interrupting the transmission of the first service signal starts from a starting position (that is, the timing t 1 ) of the resource conflict, and ends at the original ending position (that is, a timing t 3 ) of the transmission of the first service signal. In this manner, it is understandable that the first service signal will not be transmitted. 
     As shown in  FIG. 6 , in the mode shown in  FIG. 6 , a resource conflict between a time-frequency resource  20  of a further service signal and a time-frequency resource  10  of the first service signal starts at a time during transmission of the first service signal (that is, a timing t 4  in the figure), and the conflict ends at a timing before an original ending position of the first service signal (that is, a timing t 5  in the figure). In this situation, interrupting the transmission of the first service signal starts from a starting position (that is, the timing t 4 ) of the resource conflict, and ends at the original ending position (that is, a timing t 6 ) of the transmission of the first service signal. In this manner, it is understandable that a portion of the first service signal corresponding to a time-frequency resource  11  will be transmitted while a portion thereof corresponding to a time-frequency resource  12  will not be transmitted. 
     As shown in  FIG. 7 , in the mode shown in  FIG. 7 , a resource conflict between a time-frequency resource  20  of a further service signal and a time-frequency resource  10  of the first service signal starts at a time during the transmission of the first service signal (that is, a timing t 7  in the figure), and the conflict ends at a timing at an original ending position of the first service signal (that is, a timing t 8  in the figure). In this situation, interrupting the transmission of the first service signal starts from a starting position (that is, the timing t 7 ) of the resource conflict, and ends at the original ending position (that is, the timing t 8 ) of the transmission of the first service signal. In this manner, it is understandable that a portion of the first service signal corresponding to a time-frequency resource  11  will be transmitted while a portion thereof corresponding to a time-frequency resource  12  will not be transmitted. 
     It should be noted that, as a manner, if a transmission-interrupted service signal corresponding to the first service signal is not decoded successfully, the transmission-interrupted service signal will be retransmitted. 
     The signal transmission method provided in the present application can allows for: acquiring transmission configuration information of a first service signal, where the transmission configuration information includes a first time-frequency resource allocated to the first service signal; and then when receiving resource indication information representing occupancy of a signal transmission resource by a device other than the mobile terminal, if it is determined, according to the transmission configuration information and the resource indication information, to interrupt transmission of the first service signal in the first time-frequency resource, determining a starting position and/or an ending position at which the transmission of the first service signal is interrupted. With the aforementioned manner, it is achieved that, after the first time-frequency resource of the first service signal to be transmitted is acquired, the starting position and/or the ending position at which the transmission of the first service signal is interrupted in the first time-frequency resource can be further determined according to the received resource indication information, thereby achieving that usage efficiency of signal transmission resources is improved as much as possible on the premise that signal transmission can be stably performed. 
     Reference may be made to  FIG. 8 , where the present application provides a signal transmission method applied to a mobile terminal, including: 
     S 210 : acquiring transmission configuration information of a first service signal, where the transmission configuration information includes a first time-frequency resource allocated to the first service signal. 
     S 220 : receiving resource indication information, where the resource indication information is used to indicate a second time-frequency resource in which transmission of a second service signal exists. 
     S 230 : determining, according to the resource indication information and a service priority further included in the transmission configuration information, whether to interrupt transmission of the first service signal in the first time-frequency resource. 
     S 240 : if it is determined, according to the resource indication information and the service priority further included in the transmission configuration information, to interrupt transmission of the first service signal in the first time-frequency resource, determining a starting position and/or an ending position at which the transmission of the first service signal is interrupted. 
     It should be noted that different service signals may be configured with different service priorities due to different transmission contents to be realized. Taking both a URLLC service and an eMBB service as an example, the URLLC service is generally applied in a scenario requiring instantaneous transmission, such as an unmanned driving scenario and a real-time VR image transmission scenario. If the instantaneous transmission of the URLLC service cannot be guaranteed, a serious consequence may be incurred. For example, in the unmanned driving scenario, a vehicle needs to transmit traffic information to a cloud side in real time so that a driving decision can be made at the cloud side; if the traffic information cannot be uploaded to the cloud side in time, it may cause the cloud side unable to make a correct driving decision in time. The eMBB service is generally applied in a communication scenario between mobile terminals. Then through the foregoing comparison, in one mode, the URLLC service may be configured to have a service priority higher than a service priority of the eMBB service. 
     As a manner, the if it is determined, according to the resource indication information and the service priority further included in the transmission configuration information, to interrupt transmission of the first service signal in the first time-frequency resource, determining the starting position and/or the ending position at which the transmission of the first service signal is interrupted includes: 
     if there is a conflicting resource between the first time-frequency resource and the second time-frequency resource, and the second service signal has a service priority higher than the service priority of the first service signal, determining to interrupt the transmission of the first service signal in the first time-frequency resource; or, if there is no conflicting resource between the first time-frequency resource and the second time-frequency resource, or the second service signal has a service priority lower than or equal to the service priority of the first service signal, determining not to interrupt the transmission of the first service signal in the first time-frequency resource. 
     In an implementation, a starting position of the conflicting resource is the starting position at which the transmission of the first service signal is interrupted; and/or, an ending position of the first time-frequency resource is the ending position at which the transmission of the first service signal is interrupted. 
     It should be noted that after acquiring the resource indication information, the mobile terminal may detect, from the resource indication information, which signal transmission resources are currently being occupied and what types of the services occupying the signal transmission resources are. Furthermore, with this manner, a second service signal for which a corresponding time-frequency resource conflicts with the first time-frequency resource can be acquired. After the second service signal is acquired, a corresponding service priority can be queried through the service type of the second service signal. As a manner, a mapping relationship between service types and service priorities may be locally stored in the mobile terminal, then in this manner, the mobile terminal may acquire the service priority of the second service signal by querying the mapping relationship. 
     It should be noted that, in an embodiment of the present application, the first service signal may be a URLLC service, or may be an eMBB service. The second service signal may be a URLLC service, or may be an eMBB service. Exemplarily, as shown in  FIG. 9 , a conflicting resource  21 , a conflicting resource  22 , and a conflicting resource  23  in  FIG. 9  respectively correspond to three conflicting modes between the second time-frequency resource and the first time-frequency resource. Among them, the conflicting resource  21  corresponds to a resource conflict occurring at the beginning of the transmission of the first service signal, and the conflicting resource  22  and the conflicting resource  23  correspond to resource conflicts occurring during the transmission of the first service signal, except that the conflict corresponding to the conflicting resource  22  ends at a position before the original ending position of the transmission of the first service signal. Then, in the situation shown in  FIG. 9 , under a circumstance that the URLLC service has a service priority higher than a service priority of the eMBB service, if the first service signal is the URLLC service and the second service signal is the eMBB service, the transmission of the first service signal will not be interrupted regardless of the conflict mode corresponding to any conflicting resource of the conflicting resource  21 , the conflicting resource  22  and the conflicting resource  23 ; if the first service signal is the eMBB service and the second service signal is the URLLC service, the first service signal will be interrupted regardless of the conflicting mode among the conflicting resource  21 , the conflicting resource  22  and the conflicting resource  23 . For a specific starting position and ending position at which the transmission is interrupted, reference may be made to the content in the foregoing embodiments. 
     In a manner, even if the first service signal and the second service signal have a same service category, different service priorities may be configured accordingly. In this manner, in an implementation, in addition to identifying a service type of a service occupying a signal transmission resource, a device that generates the resource indication information can also identify the service occupying the signal transmission resource being performed by what kind of terminal. For example, even all services are URLLC services, they may be transmitted by a vehicle-mounted terminal device, or transmitted by a VR device. Then, in this manner, in addition to both determining the type of the second service signal and determining the second service signal being performed by what kind of terminal, the mobile terminal may further compare the type of the terminal transmitting the second service signal with its own type to determine whether to interrupt transmission of the first service signal. 
     With the aforementioned manner, the signal transmission method provided in the present application achieves that after the first time-frequency resource of the first service signal to be transmitted is acquired, the starting position and/or the ending position at which the transmission of the first service signal is interrupted in the first time-frequency resource can be further determined according to the received resource indication information, thereby achieving that usage efficiency of signal transmission resources is improved as much as possible on the premise that signal transmission can be stably performed. Moreover, in an embodiment of the present application, the transmission configuration information includes a service priority, thereby achieving that the starting position and/or the ending position at which the transmission of the first service signal is interrupted in the first time-frequency resource are determined according to the service priority included in the transmission configuration information and the resource indication information. 
     Reference may be made to  FIG. 10 , where the present application provides a signal transmission method applied to a mobile terminal, including: 
     S 310 : acquiring transmission configuration information of a first service signal, where the transmission configuration information includes a first time-frequency resource allocated to the first service signal. 
     S 320 : receiving resource indication information, where the resource indication information is used to indicate a second time-frequency resource in which transmission of a second service signal exists. 
     S 330 : determining, according to the resource indication information and a service type further included in the transmission configuration information, whether to interrupt transmission of the first service signal in the first time-frequency resource. 
     S 340 : if it is determined, according to the resource indication information and the service type further included in the transmission configuration information, to interrupt transmission of the first service signal in the first time-frequency resource, determining a starting position and/or an ending position at which the transmission of the first service signal is interrupted. 
     As a manner, the determining, according to the service type and the resource indication information, whether to interrupt transmission of the first service signal in the first time-frequency resource includes:
