Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, a terminal device, and a network device for switching a communication scenario

Background

During mobile data communication, power change or resource block hopping (RB hoping) often occurs. For example, a communication signal is switched from a New Radio (NR) signal to a Long Term Evolution (LTE) signal. At this time, a switching time for switching the communication signal needs to be limited to avoid the problem of an increase in demodulation error rate due to a power change or resource block hopping. Based on this, 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 in the original communication scenario is limited by the transition time (Tp 1) from ON to OFF, the switching time of the sub-frame or time slot in the original communication scenario to the sub-frame or time slot in the new communication scenario, and the signal power in the new communication scenario is limited by the transition time (Tp 2) from OFF to ON. In general, the ue needs to switch signals according to the requirements of the time templates.

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

Before describing the specific embodiments of the present application, the terminology referred to in the present application will be explained:

transition period (Tp): the shortest time required for power on or off;

time template (Time mask): the method comprises a first transition time period, a switching time period required by time resource switching and a second transition time period. The time required for the operation of turning off the signal power in the signal switching operation in the following embodiment is a first transition time, the time required for the operation of switching the time resource is a switching time, and the time required for the operation of turning on the signal power is a second transition time.

Side Link (SL): a Device-to-Device (D2D) communication link.

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

Communication scene switching: when the first communication scene is switched to the second communication scene, the signal power of the first communication scene is required to be closed, then the first time domain resource of the first communication scene is switched to the time domain resource of the second communication scene, and then the signal power of the second communication scene is started, so that the process of switching the first communication scene to the second communication scene is completed.

At present, when determining the corresponding resource position for executing the communication scene switching operation, the conventional technology particularly switches the 5G communication scene to the communication scene of other modes, or switches the communication scene of other modes to the communication scene of 5G mode, because the communication scene of 5G mode is a new communication scene, the related protocol has less limitation on the time domain resource of 5G mode, so when performing the mutual switching between the communication scene of other modes and the communication scene of 5G mode, the resource position corresponding to the time template is usually set on the time domain resource of 5G mode. With the deep development of 5G technology, switching from a 5G communication scene to a communication scene of another system, or switching from a communication scene of another system to a communication scene of a 5G system, is becoming more and more common, and flexibility of a resource position corresponding to a time template determined based on a conventional technology is not enough.

Based on the above conventional technology, the embodiment of the present application provides a communication scenario switching method, where the 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 set on a first time domain resource and a second time domain resource according to a transition duration required by a power switch transition when the terminal device performs a communication scenario switching, and a symbol length of a last symbol of a first time domain resource in a current communication scenario, so as to improve flexibility of the determined target resource location.

The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail 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 body of the method may be the first terminal device 100 or the access network device 300 in the scenario shown in fig. 1, and this embodiment relates to a specific implementation procedure of how to determine the target resource location for performing the communication scenario switching operation. As shown in fig. 2, the method comprises the steps of:

S201, acquiring the transition time length of the power switch communication scene of the terminal equipment.

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 on, a period of time is generally required to enable the power to reach a preset power value, so the longest time period required for turning on or off the signal power is generally determined as a transition time period, so that the signal power can be turned on or off within the transition time period. It should be noted that, closing or opening a power switch may refer to a specific closing or opening switch or a device, for example, the device may refer to a power amplifier, and opening a power switch may refer to opening a power amplifier and related switches. When starting the power of a new communication scene, it usually needs T μs to change the power from 0 to XdBm, where X is a preset power value and T is a transition period. It should be noted that the transition time is the longest time required by the preset power on or off, and the time required by the terminal device when actually turning on or off the power is usually not longer than the transition time.

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

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

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

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

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

The signal switching operation may be an operation required to switch the terminal device from the first communication scenario to the second communication scenario, and the signal switching operation may be one operation or a plurality of operations. Optionally, the signal switching operation may be an operation of turning off the 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, and the specific content of the signal switching operation is not limited in this embodiment, so long as the operation includes an operation required for switching the terminal device from the first communication scenario to the second communication scenario.

After the terminal device acquires the transition duration and the symbol length of the last symbol, the signal switching operation performed by the terminal device at the target resource location can be determined. Optionally, the terminal device may determine the signal switching operation performed at the target resource location according to the size of the symbol length of the last symbol and the transition time length, or determine the signal switching operation performed at the target resource location according to the ratio between the symbol length of the last symbol and the transition time length, or even determine the signal switching operation performed at the target resource location according to the size relationship between the difference between the symbol length of the last symbol and the difference threshold, which is not limited by the specific manner how the terminal device determines the signal switching operation that can be performed by the terminal device at the target resource location, so long as the transition time length and the symbol length are utilized.

Alternatively, the "signal switching operation that the terminal device can perform at the target resource location" may be: all operations in the signal switching operation are carried out on the first time domain resource; part of operations in signal switching operations can also be performed on the first time domain resource, and the other part of operations can be performed on the second time domain resource in the second communication scene; it is also possible to allocate a part of one of the signal switching operations to be performed on the first time domain resource, and another part of the one of the signal switching operations to be performed on the second time domain resource, which is not limited in the 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 scene, but also occupy the first time domain resource in the first communication scene and the second time domain resource in the second communication scene at the same time, and in particular how to occupy the first time domain resource and the second time domain resource in the second communication scene depends on the acquired transition duration and the symbol length of the last symbol. After determining the signal switching operation that the terminal device can execute at the target resource location, the method is actually equivalent to determining a 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 has higher flexibility.

According to the signal switching method, the transition time length of the power switch communication scene switching of the terminal equipment and the symbol length of the last symbol of the first time domain resource in the first communication scene are obtained, and then the signal switching operation of at least one operation required by the terminal equipment to switch from the first communication scene to the second communication scene can be determined on the target resource position according to the transition time length and the symbol length, wherein the target resource position comprises the first time domain resource or comprises the first time domain resource and the second time domain resource of the terminal equipment to switch from the second communication scene, that is, the determined target resource position for the terminal equipment to execute the communication scene switching operation can be flexibly arranged on the first time domain resource or on the first time domain resource and the second time domain resource according to the transition time length of the last symbol of the first time domain resource of the terminal equipment to execute the communication scene switching operation.

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

When determining the signal switching operation that the terminal device can execute at the target resource location according to the transition duration and the symbol length, the signal switching operation may be determined according to the first transition duration and the symbol length of the terminal device when the first communication scene is switched, or may be determined according to the second transition duration and the symbol length of the terminal device when the second communication scene is switched, which is not limited in the embodiment of the present application. A specific procedure for determining the target resource location based on the first transition length and the symbol length is described below by the following embodiments.

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

When a first transition duration of the terminal device during communication scene switching is obtained, a symbol length of a 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, a first signal switching operation performed on the first time domain resource includes: closing the power switch and switching the time domain resource. Optionally, the terminal device may restart performing switching of the time domain resource at intervals of a preset duration after the power switch is turned off on the first time domain resource, where the preset duration may be greater than or equal to the first transition duration, which 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 the power switch is turned off by a first transition period. 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 by a first transition duration, that is, the first signal switching operation indicates a time sequence of executing the two operations of turning off the power switch and switching the time domain resource and a specific symbol position occupied by executing 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 part of the process of switching the time domain resource, and another part of the process of switching the time domain resource is performed on the second time domain resource described below.

In addition, when the symbol length is greater than or equal to the first transition duration, 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 handover time domain resource occurring on the second time domain resource is another part of the above-mentioned handover time domain resource procedure. And after the operation of switching the time domain resources is finished, the terminal equipment starts a power switch.

It should be noted that, the time period required for switching the time domain resource may be represented by a switching time period, and the switching time period may be a preset time period. In general, the time duration required for switching the time domain resources is not longer than the time duration required for switching the time domain resources actually.

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

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

When the first transition time length of the terminal device during 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 time length, and if the symbol length is greater than or equal to the first transition time length, the first signal switching operation performed on the first time domain resource may only include: 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. Alternatively, the terminal device may execute switching of the time domain resources at preset time intervals on the second time domain resources after turning off the power switch until the first time domain resources end. Optionally, the above first signal switching operation may be used to instruct the terminal device to perform switching of the time domain resources immediately after the power switch is turned off until the first time domain resources are over. Optionally, the first signal switching operation includes the terminal device turning off the power switch on a last symbol of the first time domain resource. The embodiment of the present application does not limit the specific time at which to start to perform the power switch closing, as long as the terminal device can start to perform the power switch closing from the time and can complete the power switch closing operation when the last symbol ends. That is, the above-described first signal switching operation indicates the timing of performing the operation of turning off the signal power and the specific symbol position occupied by performing the operation.

In addition, when the symbol length is greater than or equal to the first transition duration, 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 handover time domain resource occurring on the second time domain resource is the whole process of the handover time domain resource. And after the operation of switching the time domain resources is finished, the terminal equipment starts a power switch. Optionally, the terminal device may restart switching the time domain resources at a preset time interval after the second time domain resources start, or may restart switching the time domain resources at a preset number of symbols after the second time domain resources start. Optionally, the second signal switching operation includes that the terminal device switches the time domain resources at a second time domain resource start time, and opens the power switch after the time domain resources are switched.

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

When the first transition time length of the terminal device in 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 time length, and if the symbol length is smaller than the first transition time length, the first signal switching operation performed on the first time domain resource may only include: 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, the resources occupied by the first transition duration of the communication scene switch are partially on the last symbol of the first time domain resource, and partially on the second time domain resource.

Optionally, the above-mentioned first signal switching operation may be used to instruct the terminal device to perform switching of the time domain resource on the second time domain resource immediately after the first transition period is set after the power switch is turned off. Optionally, the first signal switching operation includes that the terminal equipment turns off the power switch at the last symbol of the first time domain resource, and the second signal switching operation includes that the time domain resource is switched at a preset time, and the power switch is turned on after the time domain resource is switched; the preset time is a time after the time when the power switch is turned off by a first transition time length. That is, the above-described first signal switching operation indicates the timing of performing the operation of turning off the power switch and the specific symbol position occupied by performing the operation.

The above-described embodiments describe a specific procedure of how to determine the target resource location according to the first transition period and the symbol length, and a specific case of how to determine the target resource location according to the second transition period and the symbol length is described below by the following embodiments.

In one embodiment, the transition time period required by the terminal device to obtain the power switch transition when the communication scene is switched may be a second transition time period required by the terminal device to turn on the power switch when the second 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 terminal device performs the first signal switching operation on the first time domain resource includes: turning off the power switch, switching time domain resources, and turning on the power switch. .

When the second transition time length of the terminal device during the communication scene switching is acquired, the symbol length of the last symbol of the second time domain resource may be compared with the second transition time length, and if the symbol length is greater than or equal to the second transition time length, the first signal switching operation performed on the first time domain resource may include: turning off the power switch, switching time domain resources, and turning on the power switch. Alternatively, the terminal device may perform handover of the time domain resource on the first time domain resource. Optionally, the first signal switching operation includes the terminal device performing power switch off and time domain resource switching on other symbols before the last symbol, and 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 the start time of the last symbol of the first time domain resource, or may turn on the power switch at a time preset in the last symbol of the first time domain resource, which is not limited in this embodiment of the present application. That is, the first signal switching operation indicates the timing of 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.

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 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 terminal device performs the first signal switching operation on the first time domain resource includes: turning off the power switch, switching time domain resources, and turning on the power switch.

When the second transition time length of the terminal device during the communication scene switching is acquired, the symbol length of the last symbol of the second time domain resource may be compared with the second transition time length, and if the symbol length is smaller than the second transition time length, the first signal switching operation performed on the first time domain resource may include: turning off the power switch, switching time domain resources, and turning on the power switch. Optionally, the first signal switching operation is used for instructing the terminal device to turn off the power switch on the first time domain resource and switch the time domain resource, and performing power switch on the adjacent symbol before the last symbol and the last symbol. It should be noted that, in this embodiment, the resources required for the second transition period required for the terminal device to perform the power switch on operation may be partially placed on the last symbol of the first time domain resource, and partially placed on the adjacent symbol before the last symbol. That is, the above-described first signal switching operation indicates the timing at which the three operations of turning off the power switch, switching the time domain resource, and turning on the power switch are performed, and the specific symbol positions occupied by the three operations are performed.

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 as to improve flexibility of the location where the target resource is located.

When the second transition time length of the terminal device during the communication scene switching is acquired, the symbol length of the last symbol of the second time domain resource may be compared with the second transition time length, and if the symbol length is smaller than the second transition time length, the first signal switching operation performed on the first time domain resource may include: and closing the power switch, switching time domain resources and opening the power switch. In this embodiment, the terminal device performs the resources required for the second transition period required for turning on the power switch, a part of which is placed on the last symbol of the first time domain resource, and another part of which is placed on the second time domain resource. Optionally, the first signal switching operation is used for indicating 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 at the last symbol. The first signal switching operation indicates the timing of performing 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 the transmission characteristic of the last symbol, may be that the symbol is specially used to adjust the guard interval, may indicate that the symbol can be used for signal transmission, and may indicate that the symbol is a blank symbol that is not scheduled, which is not limited in the embodiment of the present application. If the current scenario is LTE SL, the configuration information of the last symbol is typically 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, determining signal switching operation which can be executed by the terminal equipment at the target resource position according to the configuration information of the last symbol, the transition time length and the symbol length.

After the configuration information of the last symbol is obtained, the signal switching operation which can be executed by the terminal equipment at the target resource position can be determined according to the configuration information, the transition time length and the symbol length of the last symbol. Particularly when the configuration information of the last symbol indicates that the symbol is exclusively used for adjusting the guard interval, the symbol can be fully utilized, and the terminal device can perform signal switching operation on the symbol.

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

When the configuration information of the last symbol indicates that the symbol is specially used for adjusting the guard interval, if the symbol length is greater than or equal to the first transition duration, determining that the terminal device performs the first signal switching operation on the first time domain resource includes: and closing the power switch, wherein 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. The second signal switching operation is used for indicating the terminal equipment to switch the time domain resources at the starting time of the second time domain resources, and opening the power switch after the time domain resources are switched.

When the configuration information of the last symbol indicates that the symbol is specially used for adjusting the guard interval, if the symbol length is smaller than the first transition duration, determining that the terminal equipment performs the first signal switching operation on the first time domain resource includes: closing the power switch, and determining a second signal switching operation performed by the terminal device on a 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 turns off the power switch at the last symbol of the first time domain resource, and the second signal switching operation comprises that the time domain resource is switched at a preset time, and the power switch is turned on after the time domain resource is switched; the preset time is a time after the time when the power switch is turned off by a first transition time length.

When the configuration information of the last symbol indicates that the symbol is specially used for adjusting the guard interval, 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: and closing the power switch, switching time domain resources and opening the power switch. The first signal switching operation includes that the terminal equipment performs power switch closing and time domain resource switching on other symbols before the last symbol, and power switch opening on the last symbol.

When the configuration information of the last symbol indicates that the symbol is specially used for adjusting the guard interval, if 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 comprises: turning off the power switch, switching time domain resources, and turning on the power switch. The first signal switching operation includes that the terminal equipment turns off the power switch on the first time domain resource, performs switching on the time domain resource, and turns on the power switch on an adjacent symbol before the last symbol.

When the configuration information of the last symbol indicates that the symbol is specially used for adjusting the guard interval, if 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 comprises: and closing the power switch, switching time domain resources and opening the power switch. The first signal switching operation is used for indicating the terminal equipment to switch off the power switch on the first time domain resource, switch the time domain resource and switch on the power switch on the last symbol.

According to the signal switching method, after the terminal equipment acquires 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 blank, the configuration information of the last symbol is introduced on the basis of the transition time length and the symbol length and is used as a factor for determining the signal switching operation which can be executed by the terminal equipment at the target resource position, so that the flexibility of the signal switching operation which can be executed by the terminal equipment at 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 the preset configuration information, transition duration and symbol length of the last symbol, where the configuration information is used to indicate that the last symbol is used to adjust the guard interval, that the last symbol is used for signal transmission, or that the last symbol is blank 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 to adjust the guard interval, the last symbol can be used for signal transmission, or the last symbol is blank and is not scheduled. The signal switching operation that the terminal device determines that the terminal device can execute at the corresponding resource position in specific terms of the configuration information, the transition duration and the symbol length of the last symbol, which are preset, may be similar to those described in the foregoing embodiments, and will not be repeated here.

On the basis of the above-described embodiments, it is also possible to determine whether a symbol can also be used for data transmission by determining the occupied length of the occupied symbol for performing the signal switching operation, and the symbol length of the symbol, as will be described below with reference to the embodiments shown in fig. 4 to 6.

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

s401, determining the occupied length of the signal switching operation on the target symbol; the target symbol comprises a last symbol, a symbol contiguous with 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 the signal switching operation, the last symbol on the first time domain resource or the symbol adjacent to the last symbol in the first time domain resource may be used as the start 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 the end symbol of the signal switching operation, where these target symbols may be occupied only partially. The embodiments of the present application describe whether these target symbols can be used for data transmission based on the fact that these target symbols are only partially occupied. When the occupied length occupied by the signal switching operation on the target symbol is obtained, the occupied length may be determined according to the power change value on the target symbol, for example, the length in the symbol in which the power change value exceeds the preset threshold may be determined as the occupied length.

S402, determining whether the target symbol is available for signal transmission based on the occupied length and the symbol length of the target symbol.

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

The overlapping relationship may indicate a proportion 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. For example, the target symbol may be used for signal transmission when the overlap relationship is less than a preset overlap threshold. Alternatively, it may also be determined whether the target symbol can be used for signal transmission based on the overlapping relationship and the modulation-demodulation method of the target symbol. Because the different modulation and demodulation methods have different requirements on the performance, the target symbol corresponding to the modulation and demodulation method with high performance requirement can not be used for signal transmission based on the different modulation and demodulation methods. For example, the EVM performance in 256QAM is very high, and when the modulation and demodulation method corresponding to the target symbol is 256QAM, no matter whether the overlapping relationship of the target symbol is smaller than the preset overlapping threshold, the target symbol is not used for signal transmission.

In one embodiment, as shown in fig. 5, the step 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" one possible implementation method includes:

s501, the proportion of the occupied length to the symbol length of the target symbol is obtained.

S502, if the ratio is greater than or equal to a first threshold value, determining that the target symbol is unavailable for signal transmission.

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

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

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

S602, if the length of the residual symbol is smaller than a second threshold value, determining that the target symbol is not available 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 the embodiment of the present application.

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

According to the signal switching method, 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 is determined, and whether the target symbol can be used for signal transmission or not is determined 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.

Since the subcarrier intervals in LTE are 15KHz, the symbol length of the symbol of the time domain resource in LTE can be determined to be 6667 mu S according to the 15KHz subcarrier intervals in LTE, namely the symbol length of the last symbol is determined to be 66.67 mu S; on the time domain resource of NR, the subcarrier interval may be 15KHz, 30KHz, 60KHz or 120KHz, and the symbol length of the symbol on the corresponding time domain resource of NR may be determined to be 66.67 μS, 33 μS, 17 μS or 8.5 μS according to the subcarrier interval.

Optionally, the switching communication scenario includes:

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

the communication scene of the new wireless NR system SL is switched to the communication scene of the new wireless NR system air interface Uu;
