Background

In the process of mobile data communication, power variation or resource block hopping (RB hopping) often occurs. For example, the communication signal is switched from a New Radio (NR) signal to a Long Term Evolution (LTE) signal. At this time, the switching time for switching the communication signal needs to be limited to avoid the problem of the increase of the demodulation error rate due to the power change or the resource block hopping. Based on this situation, a Time template (Time mask) is introduced in the 3GPP protocol, which specifies some Time constraints for switching from a signal in an original communication scenario to a new communication scenario, including: the signal power is limited by the ON to OFF transition time (Tp1) in the original communication scenario, by the switching time limit of the switching from the subframe or slot in the original communication scenario to the subframe or slot in the new communication scenario, and by the OFF to ON transition time (Tp2) in the new communication scenario. Generally, the user terminal needs to switch and transmit signals according to the requirements of the time template.

With the deep development of the 5G technology, at present, a communication scene switched from a 5G communication scene to a communication scene of other systems, or a communication scene switched from a communication scene of other systems to a communication scene of 5G systems, is more and more common, and switching of signals based on the provision of a time template in the conventional technology cannot meet the current scene switching requirement, and the disadvantage of insufficient flexibility is more and more obvious.

Before describing specific embodiments of the present application, the terms referred to in the present application are explained:

transition period (Tp): the shortest duration required when the power is turned on or off;

time template (Time mask): the method comprises a first transition duration, a switching duration required by time resource switching and a second transition duration. In the following embodiments, a time length required for an operation of turning off signal power in a signal switching operation is a first transition time length, a time length required for an operation of switching time resources is a switching time length, and a time length required for an operation of turning on signal power is a second transition time length.

Sidelink (SL for short): Device-to-Device (D2D) communication link.

Air interface Uu: virtual interface for wireless transmission between an access network device and a terminal device.

Switching communication scenes: when the first communication scenario is switched to the second communication scenario, the signal power of the first communication scenario needs to be turned off, the first time domain resource of the first communication scenario is switched to the time domain resource of the second communication scenario, and then the signal power of the second communication scenario is turned on, so as to complete the process of switching the first communication scenario to the second communication scenario.

At present, when a corresponding resource location for performing a communication scene switching operation is specifically determined in the conventional technology, especially a 5G communication scene is switched to a communication scene of another system, or a communication scene of another system is switched to a communication scene of a 5G system, because the communication scene of the 5G system is a new communication scene, and a related protocol has less limitation on a time domain resource of the 5G system, when a communication scene of another system and a communication scene of the 5G system are switched to each other, a resource location corresponding to a time template is usually set on the time domain resource of the 5G system. With the deep development of the 5G technology, switching from a 5G communication scenario to a communication scenario of another system, or switching from a communication scenario of another system to a communication scenario of a 5G system is more and more common, and the flexibility of the resource location corresponding to the time template determined based on the conventional technology is insufficient.

Based on the foregoing conventional technology, an embodiment of the present application provides a communication scenario switching method, where a determined target resource location for a terminal device to perform a communication scenario switching operation may be flexibly set on a first time domain resource or on the first time domain resource and a second time domain resource according to a transition duration required by a power switch for a terminal device to transition when the terminal device performs a communication scenario switching and a symbol length of a last symbol of the first time domain resource in a current communication scenario, so that flexibility of the determined target resource location is improved.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a flowchart of a communication scenario switching method according to an embodiment. The execution subject of the method may be the first terminal device 100 or the access network device 300 in the scenario shown in fig. 1, and the embodiment relates to a specific implementation process of how to determine a target resource location for performing a communication scenario switching operation. As shown in fig. 2, the method comprises the steps of:

s201, transition duration when a power switch communication scene of the terminal equipment is switched is obtained.

Specifically, the "power switch" in this embodiment may include a process of switching power from on to off, and may also include a process of switching power from off to on. When the power switch is turned off or turned on, a period of time is usually required to enable the power to reach a preset power value, and therefore, the longest duration required for turning on or off the signal power is usually determined as a transition duration, so that the signal power can be turned on or off within the transition duration. It should be noted that closing or opening a power switch may refer to a specific closing or opening switch or device, for example, the device may refer to a power amplifier, and opening a power switch may refer to opening a power amplifier and an associated switch. When the power of a new communication scenario is turned on, it usually needs T μ s to enable the power to be from 0 to XdBm, where X is a preset power value and T is a transition duration. It should be noted that the transition duration is the longest duration required for turning on or off the power in advance, and the duration required by the terminal device when actually turning on or off the power is usually not longer than the transition duration.

Optionally, the transition duration in this embodiment may be a duration required by the terminal device to switch the power from on to off in the first communication scenario, or may be a duration required by the terminal device to switch the power from off to on in the second communication scenario.

S202, obtaining the symbol length of the last symbol of the first time domain resource in the first communication scene.

The time domain resources may include a plurality of consecutive symbols, each symbol representing a frequency domain resource within a duration. The time domain resources corresponding to different communication scenarios may be the same or different, and this is not limited in this embodiment of the present application.

S203, according to the transition duration and the symbol length, determining the signal switching operation which can be executed by the terminal equipment on the target resource position.

The switching operation is used for switching the terminal device from a first communication scene to a second communication scene, and the target resource position includes a first time domain resource or includes the first time domain resource and a second time domain resource in the second communication scene.

The signal switching operation may refer to an operation required to switch the terminal device from the first communication scenario to the second communication scenario, and may be one operation or a plurality of operations. Optionally, the signal switching operation may be an operation of turning off a power switch, an operation of turning on the power switch, or a switching operation of switching from a first time domain resource in a first communication scenario to a second time domain resource in a second communication scenario.

After the terminal device obtains the transition duration and the symbol length of the last symbol, it may determine the signal switching operation performed by the terminal device on the target resource location. Optionally, the terminal device may determine the signal switching operation performed at the target resource location according to the transition duration and the symbol length of the last symbol, may also determine the signal switching operation performed at the target resource location according to a ratio between the transition duration and the symbol length of the last symbol, and may even determine the signal switching operation performed at the target resource location according to a magnitude relationship between a difference between the transition duration and the symbol length of the last symbol and a preset difference threshold.

Optionally, the "signal switching operation that the terminal device can perform at the target resource location" may be: performing all operations in the signal switching operation on the first time domain resource; or performing a part of the signal switching operation on the first time domain resource, and performing another part of the signal switching operation on the second time domain resource in the second communication scenario; in addition, a part of the operation of one of the signal switching operations may be allocated to be executed on the first time domain resource, and another part of the operation of one of the signal switching operations may be allocated to be executed on the second time domain resource, which is not limited in this embodiment of the present application.

It should be noted that, in this embodiment, the signal switching operation determined by the terminal device may not only occur on the first time domain resource in the first communication scenario, but also occupy the first time domain resource in the first communication scenario and the second time domain resource in the second communication scenario simultaneously, and how to occupy the first time domain resource in the first communication scenario and the second time domain resource in the second communication scenario depends on the obtained transition duration and the symbol length of the last symbol. After the signal switching operation that the terminal device can perform at the target resource location is determined, it is actually equivalent to determining the time template when the terminal device performs communication scene switching. Based on the above description, the resource location corresponding to the time template may include the first time domain resource, or may include the first time domain resource and the second time domain resource, which is highly flexible.

In the signal switching method, by obtaining a transition duration when a power switch communication scenario of the terminal device is switched, and a symbol length of a last symbol of a first time domain resource in a first communication scenario, and further determining, according to the transition duration and the symbol length, a signal switching operation of at least one operation that is required for the terminal device to switch from the first communication scenario to a second communication scenario and that can be executed by the terminal device in a target resource position, where the target resource position includes the first time domain resource, or includes the first time domain resource and a second time domain resource when the terminal device is switched to the second communication scenario, that is, the determined target resource position for the terminal device to execute the communication scenario switching operation, may be determined according to the transition duration required for the power switch transition when the terminal device performs the communication scenario switching, and the symbol length of the last symbol of the first time domain resource in the first communication scenario, the flexible setting has improved the flexibility of the place that the goal resource locates on the resource of the first time domain, or set up on resource of the first time domain and second time domain resource.

Optionally, the signal switching operation includes at least one of the following operations: turn off the power switch, turn on the power switch, and switch the time domain resources.

When a signal switching operation that can be executed by the terminal device at the target resource location is determined according to the transition duration and the symbol length, the signal switching operation may be determined according to a first transition duration and the symbol length when the terminal device switches over the first communication scenario, or may be determined according to a second transition duration and the symbol length when the terminal device switches over the second communication scenario, which is not limited in this embodiment of the present application. The specific process of determining the target resource location according to the first transition duration and the symbol length is described below by the following embodiments.

In one embodiment, when the terminal device acquires the first transition duration, step S203 may be: if the symbol length is greater than or equal to the first transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: and closing the power switch and switching the time domain resources, and determining that the second signal switching operation executed by the terminal equipment on the second time domain resources comprises switching the time domain resources and opening the power switch.

When the first transition duration of the terminal device at the time of communication scene switching is obtained, the symbol length of the last symbol of the first time domain resource may be compared with the first transition duration, and if the symbol length is greater than or equal to the first transition duration, the first signal switching operation performed on the first time domain resource includes: and closing the power switch and switching the time domain resources. Optionally, the terminal device may start to perform switching of the time domain resource at a preset time interval after the power switch is turned off on the first time domain resource, where the preset time interval may be greater than the first transition time interval or equal to the first transition time interval, and this is not limited in this embodiment of the present application; optionally, the terminal device may perform the operation of switching the time domain resource immediately after turning off the power switch for the first transition duration. Optionally, the first signal switching operation includes that the terminal device switches the time domain resource immediately after the power switch is turned off on the last symbol of the first time domain resource at an interval of the first transition duration, that is, the first signal switching operation indicates a timing for performing two operations of turning off the power switch and switching the time domain resource and a specific symbol position occupied by performing the two operations. It should be noted that, in this embodiment, the operation of switching the time domain resource performed on the last symbol of the first time domain resource includes a partial process of switching the time domain resource, and another partial process of switching the time domain resource is performed on the following second time domain resource.

In addition, when the symbol length is greater than or equal to the first transition time length, the terminal device further determines that the second signal switching operation performed on the second time domain resource includes switching the time domain resource and turning on the power switch. As mentioned above, the switching time domain resource occurring on the second time domain resource is another part of the above switching time domain resource. And after the operation of switching the time domain resources is finished, the terminal equipment starts the power switch.

It should be noted that the time duration required for switching the time domain resource may be represented by a switching time duration, and the switching time duration may be a preset time length. Generally, the time length required for switching the time domain resource by the terminal device is not longer than the switching time length.

As can be seen from the description of this embodiment, the signal switching operation may not only occupy the first time domain resource in the first communication scenario, but also occupy the second time domain resource in the second communication scenario, that is, the resource location occupied by the signal switching operation may be flexibly set on the first time domain resource, or on the first time domain resource and the second time domain resource, so as to improve the flexibility of the location of the target resource.

In another embodiment, when the terminal device obtains the first transition duration, step S203 may further be: if the symbol length is greater than or equal to the first transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: and closing the power switch, wherein the second signal switching operation executed by the terminal equipment on the second time domain resource comprises switching the time domain resource and opening the power switch.

When the first transition duration of the terminal device at the time of the communication scene switching is obtained, the symbol length of the last symbol of the first time domain resource may be compared with the first transition duration, and if the symbol length is greater than or equal to the first transition duration, the first signal switching operation performed on the first time domain resource may include only: the power switch is turned off. The second signal switching operation performed by the terminal device on the second time domain resource includes switching the time domain resource and turning on the power switch. Optionally, the terminal device may perform switching the time domain resource after turning off the power switch until the first time domain resource is ended, and perform switching the time domain resource at a preset time interval on the second time domain resource. Optionally, the first signal switching operation may be used to instruct the terminal device to perform switching of the time domain resource immediately after the power switch is turned off until the first time domain resource is finished. Optionally, the first signal switching operation includes the terminal device turning off the power switch on the last symbol of the first time domain resource. The terminal device may start to close the power switch at a starting time of a last symbol on the first time domain resource, or may start to close the power switch at a preset time of the last symbol on the first time domain resource. That is, the above-described first signal switching operation indicates the timing at which the operation of turning off the signal power is performed and the specific symbol position at which the operation is performed.

In addition, when the symbol length is greater than or equal to the first transition time length, the terminal device further determines that the second signal switching operation performed on the second time domain resource includes switching the time domain resource and turning on the power switch. As can be seen from the above description, the switching time domain resource occurring on the second time domain resource is the whole process of the switching time domain resource. And after the operation of switching the time domain resources is finished, the terminal equipment starts the power switch. Optionally, the terminal device may start switching the time domain resource at a preset time interval after the second time domain resource starts, or may start switching the time domain resource at a preset number of symbols at a preset time interval after the second time domain resource starts, which is not limited in the embodiment of the present application. Optionally, the second signal switching operation includes that the terminal device switches the time domain resource at the start time of the second time domain resource, and turns on the power switch after the time domain resource is switched.

As described in this embodiment, the signal switching operation may occupy not only the first time domain resource in the first communication scenario but also the second time domain resource in the second communication scenario, that is, the resource location occupied by the signal switching operation may be flexibly set on the first time domain resource, or on the first time domain resource and the second time domain resource, so as to improve the flexibility of the location of the target resource.

In another embodiment, when the terminal device obtains the first transition duration, step S203 may further be: if the symbol length is smaller than the first transition duration, determining that the first signal switching operation executed by the terminal device on the first time domain resource includes: and closing the power switch, wherein the second signal switching operation executed by the terminal equipment on the second time domain resource comprises the following steps: switching time domain resources and turning on a power switch.

When the first transition duration of the terminal device at the time of communication scene switching is obtained, the symbol length of the last symbol of the first time domain resource may be compared with the first transition duration, and if the symbol length is less than the first transition duration, the first signal switching operation performed on the first time domain resource may include only: the power switch is turned off. The second signal switching operation performed by the terminal device on the second time domain resource includes switching the time domain resource and turning on the power switch. It should be noted that, in this embodiment, a part of the resources occupied by the first transition duration of the communication scene switching is on the last symbol of the first time domain resource, and another part of the process is on the second time domain resource.

Optionally, the first signal switching operation may be used to instruct the terminal device to perform switching the time domain resource on the second time domain resource at an interval of the first transition duration after the power switch is turned off. Optionally, the first signal switching operation includes that the terminal device turns off the power switch at the last symbol of the first time domain resource, and the second signal switching operation includes switching the time domain resource at a preset time, and turning on the power switch after switching the time domain resource; the preset moment is a moment separated by a first transition duration after the moment of turning off the power switch. That is, the first signal switching operation described above indicates the timing at which this operation of turning off the power switch is performed and the specific symbol position at which this operation is performed.

The above embodiment describes a specific process of how to determine the target resource location according to the first transition duration and the symbol length, and the following embodiment describes a specific case of how to determine the target resource location according to the second transition duration and the symbol length.

In one embodiment, the transition duration required by the terminal device to acquire the transition of the power switch when the communication scene is switched may be a second transition duration required by the terminal device to turn on the power switch when the communication scene is switched. The step S203 of determining, according to the transition duration and the symbol length, a signal switching operation that can be performed by the terminal device at the corresponding resource location "may include: if the symbol length is greater than or equal to the second transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: closing the power switch, switching time domain resources and opening the power switch. .

When the second transition duration of the terminal device at the time of the communication scene switching is obtained, the symbol length of the last symbol of the second time domain resource may be compared with the second transition duration, and if the symbol length is greater than or equal to the second transition duration, the first signal switching operation performed on the first time domain resource may include: closing the power switch, switching time domain resources and opening the power switch. Optionally, the terminal device may perform switching the time domain resource on the first time domain resource. Optionally, the first signal switching operation includes that the terminal device turns off the power switch and switches the time domain resource on other symbols before the last symbol, and turns on the power switch on the last symbol. For example, the first signal switching operation may be used to instruct the terminal device to turn on the power switch at a starting time of a last symbol of the first time domain resource, or turn on the power switch at a preset time of the last symbol of the first time domain resource, which is not limited in this embodiment of the application. That is, the first signal switching operation indicates the timing for performing the three operations of turning off the power switch, switching the time domain resource and turning on the power switch, and the specific symbol position occupied for performing the three operations.

As can be seen from the description of this embodiment, the signal switching operation may occupy the first time domain resource in the first communication scenario, and in a possible case, when the first communication scenario is LTE, the corresponding resource location may be determined on the time domain resource corresponding to LTE, so that the flexibility of the determined corresponding resource location is improved.

In one embodiment. The step S203 of determining, according to the transition duration and the symbol length, a signal switching operation that can be performed by the terminal device at the corresponding resource location "may include: if the symbol length is smaller than the second transition duration, determining that the first signal switching operation executed by the terminal device on the first time domain resource includes: closing the power switch, switching time domain resources and opening the power switch.

When the second transition duration of the terminal device during the communication scene switching is obtained, the symbol length of the last symbol of the second time domain resource may be compared with the second transition duration, and if the symbol length is smaller than the second transition duration, the first signal switching operation performed on the first time domain resource may include: closing the power switch, switching time domain resources and opening the power switch. Optionally, the first signal switching operation is used to instruct the terminal device to turn off the power switch on the first time domain resource and to switch the time domain resource, and to turn on the power switch on an adjacent symbol before the last symbol and the last symbol. It should be noted that, in this embodiment, a part of the resources required for the second transition duration required for the terminal device to perform the power-on switching operation may be placed on the last symbol of the first time domain resource, and another part may be placed on the adjacent symbol before the last symbol. That is, the first signal switching operation indicates the timing for performing the three operations of turning off the power switch, switching the time domain resource, and turning on the power switch, and the specific symbol positions occupied for performing the three operations.

As can be seen from the description of this embodiment, the signal switching operation may occupy the first time domain resource in the first communication scenario, and in a possible case, when the first communication scenario is LTE, the target resource location may be determined on the time domain resource corresponding to LTE, so that the flexibility of the location of the target resource is improved.

In this embodiment, the terminal device executes the resources required for the second transition duration required for turning on the power switch, where one part is placed on the last symbol of the first time domain resource and the other part is placed on the second time domain resource. Optionally, the first signal switching operation is used to instruct the terminal device to turn off the power switch on the first time domain resource, switch the time domain resource, and turn on the power switch on the last symbol. The first signal switching operation indicates the timing for performing the three operations of turning off the power switch, switching the time domain resource and turning on the power switch, and the specific symbol positions occupied by performing the three operations. .

In a possible embodiment, when determining the corresponding resource location, the signal switching operation that can be performed by the terminal device at the corresponding resource location may also be determined according to the configuration information of the last symbol, the transition duration, and the symbol length. Optionally, as shown in fig. 3, the method further includes:

The configuration information may be used to indicate a transmission characteristic of a last symbol, where the last symbol is used to adjust a guard interval, may also indicate that the last symbol can be used for signal transmission, and may also indicate that the last symbol is a blank symbol that is not scheduled, which is not limited in this embodiment of the present application. If the current scenario is LTE SL, the configuration information of the last symbol is usually fixedly set to indicate that the last symbol is dedicated to adjusting the guard interval. If the current scene is NR sidelink, the configuration information of the last symbol is also fixedly set to indicate that the last symbol is specially used for adjusting the guard interval.

S302, according to the configuration information, the transition duration and the symbol length of the last symbol, determining the signal switching operation which can be executed by the terminal equipment on the target resource position.

After the configuration information of the last symbol is obtained, the signal switching operation that can be performed by the terminal device at the target resource location can be determined according to the configuration information of the last symbol, the transition duration and the symbol length. In particular, if the configuration information of the last symbol indicates that this symbol is used exclusively for adjusting the guard interval, then this symbol can be fully utilized, on which the terminal device can perform a signal switching operation.

For example, when the configuration information of the last symbol indicates that the symbol is dedicated to adjusting the guard interval, then when the symbol length is greater than or equal to the first transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: and closing the power switch and switching the time domain resources, and determining that the second signal switching operation executed by the terminal equipment on the second time domain resources comprises opening the power switch. The first signal switching operation comprises that the terminal equipment switches the time domain resources at the interval of a first transition duration after the terminal equipment closes the power switch on the last symbol of the first time domain resources.

When the configuration information of the last symbol indicates that the symbol is dedicated to adjusting the guard interval, and when the symbol length is greater than or equal to the first transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: and closing the power switch, and determining that the second signal switching operation performed by the terminal equipment on the second time domain resource comprises switching the time domain resource and opening the power switch. Wherein the first signal switching operation comprises the terminal device turning off the power switch on the last symbol of the first time domain resource. And the second signal switching operation is used for indicating the terminal equipment to switch the time domain resources at the starting moment of the second time domain resources and starting the power switch after the time domain resources are switched.

When the configuration information of the last symbol indicates that the symbol is dedicated to adjusting the guard interval, and when the symbol length is smaller than the first transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: turning off the power switch, and determining that the second signal switching operation performed by the terminal device on the second time domain resource includes: switching time domain resources and turning on a power switch. The first signal switching operation comprises that the terminal equipment closes a power switch at the last symbol of the first time domain resource, the second signal switching operation comprises that the time domain resource is switched at a preset moment, and the power switch is opened after the time domain resource is switched; the preset moment is a moment separated by a first transition duration after the moment of turning off the power switch.

When the configuration information of the last symbol indicates that the symbol is dedicated to adjusting the guard interval, and when the symbol length is greater than or equal to the second transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: closing the power switch, switching time domain resources and opening the power switch. The first signal switching operation comprises that the terminal equipment closes a power switch and switches time domain resources on other symbols before the last symbol, and opens the power switch on the last symbol.

The first signal switching operation comprises the steps that the terminal equipment closes the power switch on the first time domain resource, switches the time domain resource, and opens the power switch on the adjacent symbol before the last symbol.

When the configuration information of the last symbol indicates that the symbol is dedicated to adjusting the guard interval, and when the symbol length is smaller than the second transition duration, determining that the first signal switching operation performed by the terminal device on the first time domain resource includes: closing the power switch, switching time domain resources and opening the power switch. The first signal switching operation is used for instructing the terminal equipment to close the power switch on the first time domain resource, to switch the time domain resource, and to open the power switch on the last symbol.

According to the signal switching method, the terminal equipment introduces the configuration information of the last symbol on the basis of the transition duration and the symbol length after acquiring the configuration information of the last symbol, which is used for indicating that the last symbol is used for adjusting the guard interval, the last symbol can be used for signal transmission or the last symbol is not scheduled as a blank symbol, and the configuration information is used as a factor for determining the signal switching operation which can be executed by the terminal equipment on the target resource position, so that the flexibility of the signal switching operation which can be executed by the terminal equipment on the determined target resource position is further improved.

In one embodiment, the terminal device may determine the signal switching operation that the terminal device can perform at the corresponding resource location directly according to preset configuration information, a transition duration and a symbol length of a last symbol, where the configuration information is used to indicate that the last symbol is used for adjusting a guard interval, the last symbol is used for signal transmission or the last symbol is a blank symbol and is not scheduled.

In this embodiment, the configuration information of the last symbol is preset configuration information, and the configuration information is used to indicate that the last symbol is used for adjusting the guard interval, the last symbol can be used for signal transmission, or the last symbol is a blank symbol and is not scheduled. The method for determining, by the terminal device, the signal switching operation that can be performed by the terminal device at the corresponding resource location according to the configuration information, the transition duration, and the symbol length of the preset last symbol may be similar to that described in the foregoing embodiment, and details are not repeated here.

On the basis of the above-mentioned embodiments, it can also be determined whether the occupied symbol can also be used for data transmission by determining the occupied length of the occupied symbol performing the signal switching operation and the symbol length of the symbol, which is explained by the embodiments shown in fig. 4 to 6 below.

As shown in fig. 4, the method further comprises the steps of:

s401, determining the occupied length occupied by the signal switching operation on a target symbol; the target symbol includes a last symbol, a symbol adjacent to the last symbol in the first time domain resource, or a first symbol in the second time domain resource.

As can be seen from the description of the above embodiments, when performing a signal switching operation, the last symbol on the first time domain resource or a symbol adjacent to the last symbol in the first time domain resource may be used as a starting symbol of the signal switching operation, and the last symbol on the first time domain resource or the first symbol in the second time domain resource may be used as a terminating symbol of the signal switching operation, where these target symbols may be only partially occupied. The embodiment of the application is based on the fact that the target symbols are only partially occupied, and whether the target symbols can be used for data transmission is described. When the occupied length occupied by the signal switching operation on the target symbol is obtained, the occupied length may be determined according to a power variation value on the target symbol, for example, a length in a symbol in which the power variation value exceeds a preset threshold may be determined as the occupied length.

S402, whether the target symbol can be used for signal transmission is determined based on the occupation length and the symbol length of the target symbol.

When determining whether the target symbol is available for signal transmission based on the occupied length and the symbol length of the target symbol, it may be determined whether the target symbol is available for signal transmission by a difference between the occupied length and the symbol length of the target symbol, or by a ratio between the occupied length and the symbol length of the target symbol. Optionally, it is determined whether the target symbol is available for signal transmission based on an overlap relationship between the occupied length and the symbol length of the target symbol.

The overlap relationship may indicate a ratio of the occupied length to the symbol length of the target symbol, may also indicate a remaining symbol length of the target symbol except the occupied length, and may also indicate an absolute value of the occupied length, which is not limited in this embodiment of the present application. For example, when the overlap relation is smaller than a preset overlap threshold, the target symbol may be used for signal transmission. Optionally, it may also be determined whether the target symbol can be used for signal transmission based on the overlap relationship and a modulation and demodulation method of the target symbol. Because different modulation and demodulation methods have different requirements on performance, target symbols corresponding to the modulation and demodulation methods with high performance requirements are not used for signal transmission based on different modulation and demodulation methods. For example, the EVM performance requirement in 256QAM is high, and when the modulation and demodulation method corresponding to the target symbol is 256QAM, the target symbol is not used for signal transmission no matter whether the overlap relationship of the target symbol is smaller than a preset overlap threshold.

In one embodiment, as shown in fig. 5, one possible implementation method of the above-mentioned S402 "determining whether the target symbol is available for signal transmission based on the overlapping relationship between the occupied length and the symbol length of the target symbol" includes:

s501, acquiring the proportion of the occupied length to the symbol length of the target symbol.

And S502, if the proportion is larger than or equal to a first threshold value, determining that the target symbol is not available for signal transmission.

The first threshold may be a preset first threshold, or may also be a first threshold specified by a protocol, which is not limited in this embodiment of the present application.

In one embodiment, as shown in fig. 6, one possible implementation method of the above-mentioned S402 "determining whether the target symbol is available for signal transmission based on the overlapping relationship between the occupied length and the symbol length of the target symbol" includes:

s601, obtaining the remaining symbol length of the target symbol except the occupied length.

And S602, if the length of the residual symbol is smaller than a second threshold value, determining that the target symbol cannot be used for signal transmission.

The second threshold may be a preset second threshold, or a second threshold specified by a protocol, which is not limited in this embodiment of the application.

Optionally, if the occupied length is not 0, it is determined that the target symbol is not available for signal transmission.

The signal switching method determines the occupied length occupied by the signal switching operation in the last symbol, the symbol adjacent to the last symbol in the first time domain resource or the first symbol in the second time domain resource, and determines whether the target symbol can be used for signal transmission based on the occupied length and the symbol length of the target symbol. The target symbol can be used for signal switching operation and signal transmission, so that the use efficiency of the target symbol is greatly improved, and the flexibility of the target symbol is also improved.

In one embodiment, the transition duration may be determined according to a transition time capability supported by the terminal device in the current communication scenario.

In one embodiment, the symbol length of the last symbol may be determined according to the subcarrier spacing in the first communication scenario.

Because the subcarrier intervals in the LTE are all 15KHz, the symbol length of the symbol of the time domain resource in the LTE is determined to be 66.67 μ S, that is, the symbol length of the last symbol is determined to be 66.67 μ S, according to the subcarrier intervals in the LTE are all 15 KHz; on the time domain resource of NR, the subcarrier spacing may be 15KHz, 30KHz, 60KHz, or 120KHz, and then the symbol length of the symbol on the time domain resource of NR corresponding thereto may be determined to be 66.67 μ S, 33 μ S, 17 μ S, or 8.5 μ S, respectively, according to the subcarrier spacing.

Optionally, the switching communication scenario includes:

switching a side link SL communication scene of the new wireless NR system into a SL communication scene of a long term evolution LTE system;

switching the communication scene of the air interface Uu of the new wireless NR system by the communication scene of the new wireless NR system SL;

switching the communication scene of the new wireless NR system SL into the communication scene of an air interface Uu of the long term evolution LTE system;

switching the communication scene of the long term evolution LTE system SL into the communication scene of a new wireless NR system SL;

switching the communication scene of the air interface Uu of the new wireless NR system into the communication scene of the SL of the new wireless NR system;

an air interface Uu communication scene of a long term evolution LTE system is switched to a communication scene of a new wireless NR system SL;

switching a first signal into a second signal in a communication system of the same standard;

and the first channel is switched to the second channel in the communication system of the same standard.
