Background

A communication system may generally include a receiving end and a transmitting end, where the transmitting end may be, for example, a base station, and the receiving end may be, for example, a terminal.

In the prior art, for example, a sending end is a base station, and a receiving end is a terminal, where the base station is configured to send, to the terminal, subframes of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), a Physical Broadcast Channel (PBCH), a System Information (SI), and the like, which are generally subframes agreed by a protocol, and when a sending time window of other signals that the base station needs to send includes subframes for sending PSS, SSS, PBCH, SI, and the like, that is, when the subframes for sending PSS, SSS, PBCH, SI, and the like collide with the subframes for sending PSS, SSS, PBCH, SI, and the like, the collision may be resolved in any one of the following two manners: firstly, in a delay (postdone) mode, a time window is expanded, and the number of subframes capable of being used for transmitting other signals in the time window is a preset number; the second, drop (drop) approach, does not expand the time window, and the number of subframes within the time window that can be used to transmit other signals is less than a preset number.

However, with the prior art, the power consumption of the receiving end may be large, or the coverage area of the signal may be small.

Disclosure of Invention

Embodiments of the present application provide a communication method, device, and system, so as to solve the problem in the prior art that power consumption of a receiving end may be large or an applicable coverage of a signal is small.

In a first aspect, an embodiment of the present application provides a communication method, where the communication method is performed by a communication device, and the method includes:

acquiring a first threshold and an initial position of a preset signal, wherein the first threshold is used for determining a collision resolution mode when a candidate time domain transmission unit of the preset signal collides with a specific time domain transmission unit;

and starting from the starting position, sending or receiving the preset signal according to the first threshold value.

In the above scheme, by obtaining a first threshold and an initial position of a preset signal, where the first threshold is used to determine a collision resolution mode when a candidate time domain transmission unit of the preset signal collides with a specific time domain transmission unit, and sending or receiving the preset signal according to the first threshold from the initial position, the collision resolution modes of different specific time domain transmission units can be determined according to the first threshold, so that a problem that power consumption of a receiving end is likely to be large or an applicable coverage range of the signal is small when a discarding mode or a delaying mode is adopted regardless of specific conditions is avoided.

In one possible implementation, the sending or receiving the preset signal according to the first threshold from the starting position includes:

and starting from the starting position, sending or receiving the preset signal by adopting a first collision resolution mode for the mth specific time domain transmission unit, wherein m is an integer which is greater than 0 and less than or equal to the first threshold value.

In the foregoing solution, the preset signal is sent or received by using a first collision resolution manner for the mth specific time domain transmission unit from the starting position, where m is an integer greater than 0 and less than or equal to the first threshold, so that collision resolution manners of different specific time domain transmission units can be determined according to the first threshold.

In one possible implementation, the transmitting or receiving the preset signal according to the first threshold from the starting position further includes:

and adopting a second collision resolution mode for the nth specific time domain transmission unit, wherein n is an integer greater than the first threshold value.

In the above scheme, by adopting the first conflict solution for the mth specific time domain transmission unit and the second conflict solution for the nth specific time domain transmission unit, when the number of the conflicting specific time domain transmissions is large, compromise between the two conflict solution methods can be realized, and the problem that the power consumption of the receiving end is possibly large or the applicable coverage range of the signal is small when the discarding method or the delaying method is adopted without considering specific conditions is avoided.

and if the difference degree is greater than or equal to the first threshold value, transmitting or receiving the preset signal in a discarding mode from the initial position.

In the above scheme, if the delay mode is adopted, the length of the maximum window for receiving the preset signal by the receiving end is greatly increased, and then the discarding mode is adopted, so that the problem of large power consumption of the receiving end is avoided.

In one possible implementation, the method further includes:

and if the difference degree is smaller than the first threshold value, transmitting or receiving the preset signal in a delay mode from the initial position.

In the above scheme, if the delay mode is adopted, the length of the maximum window for receiving the preset signal by the receiving end is not greatly increased, the delay mode is adopted, and therefore the power consumption of the receiving end is ensured within a reasonable range, and meanwhile, the applicable coverage range of the signal can be ensured.

judging whether the number of the specific time domain transmission units in the target time length range is less than or equal to the first threshold value from the starting position; the target duration is associated with a maximum duration of the preset signal;

and if the number of the specific time domain transmission units in the target time length range is less than or equal to the first threshold value from the starting position, transmitting or receiving the preset signal from the starting position.

In the above scheme, if the number of the specific time domain transmission units within the target time length range is small, the preset signal is sent or received from the start position, so that the specific time domain transmission units can not greatly affect the number of the time domain transmission units which can be used for transmitting the preset signal and the length of the maximum window of the receiving end for receiving the preset signal, and therefore the problem that the applicable coverage range of the signal is small due to signal collision with the specific time domain transmission units or the power consumption of the receiving end is large is solved.

In one possible implementation, the method further includes:

and taking the time length corresponding to the maximum window length of the received preset signal when the specific time domain transmission unit is discarded from the starting position determined according to the maximum duration as the target time length.

In one possible implementation, the method further includes:

and if the number of the specific time domain transmission units in the target time length range is larger than the first threshold value from the starting position, not sending or receiving the preset signal.

In the above scheme, if the number of the specific time domain transmission units in the target time length range is large, the preset signal is not sent or received, so that the influence on sending or receiving the preset signal when the number of the specific time domain transmission units is large is avoided, and the problems that the applicable coverage area of the signal is small and the power consumption of a receiving end is large due to the conflict with the specific time domain transmission units are solved.

In a design of a possible implementation, the communication device is a transmitting end, and before transmitting or receiving the preset signal according to the first threshold from the starting position, the method further includes:

and sending indication information to a receiving end, wherein the indication information is used for indicating the first threshold value.

Detailed Description

Fig. 1A is a schematic view of an application scenario in an embodiment of the present application, and as shown in fig. 1A, the application scenario in the embodiment may include: a transmitting end and a receiving end. The transmitting end and the receiving end may be collectively referred to as a communication device. The communication device may obtain a starting position of a preset signal and a first threshold, where the first threshold is used to determine a collision resolution manner when a candidate time domain transmission unit of the preset signal collides with a specific time domain transmission unit; and starting from the starting position, sending or receiving the preset signal according to the first threshold value. Here, for the sending end, specifically, the sending end may start from the starting position and send the preset signal according to the first threshold; for the receiving end, it may specifically be that the starting position starts, and the preset signal is received according to the first threshold. It should be noted that the transmitting end and the receiving end are relative concepts, and when the device 1 transmits to the device 2, the device 1 may be regarded as the transmitting end, and the device 2 may be regarded as the receiving end. When the device 2 transmits to the device 1, the device 2 may be regarded as a transmitting side and the device 1 may be regarded as a receiving side.

It should be noted that the embodiments of the present invention can be applied to any communication system involving a time domain transmission unit, such as a Long Term Evolution (LTE) system, a narrowband band internet of things (NB-IoT), a 5G New Radio (NR) system, a global system for mobile communication (GSM) system, a mobile communication system (UMTS), a Code Division Multiple Access (CDMA) system, a new network system, and the like. For example, as shown in fig. 1B, the communication system provided in this embodiment may include: base Station (BS), User Equipment (UE) 1-UE 6. When the base station serves as the transmitting end, the UE1, the UE2, the UE3 and the UE5 may serve as the receiving ends corresponding to the base station. When the base station serves as a receiving end, the UE1, the UE2, the UE3, and the UE5 may serve as corresponding transmitting ends of the base station. When the UE5 serves as a receiver, the UE4 and the UE6 may serve as a corresponding transmitter for the UE 5. When the UE5 serves as a transmitter, the UE4 and the UE6 may serve as receivers corresponding to the UE 5.

The terminal, which may also be referred to as a user equipment, may include, but is not limited to, a smart phone (e.g., an Android phone, an IOS phone, etc.), a multimedia device, a streaming media device, a personal computer, a tablet computer, a palmtop computer, a Mobile Internet Device (MID), an internet device such as a wearable smart device, and the like.

The base station may be an evolved NodeB (eNB) in LTE, or a base station in a fifth generation (5G) mobile communication system (also referred to as a New Radio (NR)), which may be referred to as a 5G base station (gnnodeb, gNB), or a relay station, or a vehicle-mounted device, a wearable device, and an access network device in a future 5G network or an access network device in a future evolved Public Land Mobile Network (PLMN) network, and the like, and the application is not limited thereto.

Optionally, the specific time domain transmission unit may specifically be a time domain transmission unit that is fixedly used for transmitting one or more specific signals, specific channels, specific data, or the like. Further, the specific time domain transmission unit may be a time domain transmission unit fixed for transmitting a System Information Block (SIB) x, where x is an integer greater than 1. Further optionally, in the narrowband internet of things, time domain transmission units for transmitting system message blocks other than the SIB1-NB are fixed, for example, SIB2-NB, SIB3-NB, and the like.

Optionally, the time domain transmission unit may be a time slot or a subframe, or other time units, which is not limited in this application.

Optionally, the preset signal may specifically be any signal that is sent by the sending end under the control of the starting position and the maximum duration. Further optionally, the preset signal may be a Wake Up Signal (WUS).

Alternatively, the candidate time domain transmission unit may be understood as a time domain transmission unit expected to be used for sending or receiving the preset signal, and specifically, the candidate time domain transmission unit may be associated with a start position and a maximum duration of the preset signal. A collision of the candidate time domain transmission unit with the particular time domain transmission unit may be understood as a candidate time domain transmission unit being a particular time domain transmission unit. Wherein the maximum duration may be expressed in terms of time, e.g., 10 milliseconds (ms); alternatively, the number of time domain transmission units may be represented, for example, 10 time domain transmission units. When 1 time domain transmission unit corresponds to 1ms, both 10ms and 10 time domain transmission units may be equivalent.

Assuming a maximum duration of 10 time domain transmission units, the delay and discard schemes are described below with reference to fig. 2A-2C:

when the candidate time domain transmission unit does not collide with the specific time domain transmission unit, the time domain transmission unit that can be used for transmitting the preset signal is the time domain transmission unit within the maximum duration T as shown in fig. 2A.

When the time domain transmission unit filled with two points in the candidate time domain transmission units is the specific time domain transmission unit and the specific time domain transmission unit filled with the two points adopts the delay mode, the time domain transmission unit which can be used for transmitting the preset signal is the time domain transmission unit without filling in the range of T + T 'in fig. 2B, wherein T' is the duration of the two specific time domain transmission units.

When the time domain transmission units filled with two points in the candidate time domain transmission units are the specific time domain transmission units and the time domain transmission units filled with the two points adopt the discarding mode, the time domain transmission units which can be used for transmitting the preset signal are the time domain transmission units without filling in the range of T as shown in fig. 2C.

As can be seen from fig. 2A to 2C, for the conflicting time domain transmission units, the number of the time domain transmission units that can be used for transmitting the predetermined signal is not affected by the conflict resolved in the delay manner. However, resolving the conflict by the discarding method may affect the number of time domain transmission units that can be used for transmitting the predetermined signal, i.e. the sum of the number of time domain transmission units that can be used for transmitting the predetermined signal and the number of specific time domain transmission units that resolve the conflict by the discarding method is the same as the number of time domain transmission units corresponding to the maximum duration.

It should be noted that in fig. 2A-2, a small rectangular grid can represent a time domain transmission unit.

Taking a communication system as a narrowband internet of things (NB-IoT), a transmitting end as a base station, a receiving end as a terminal, time domain transmission units for transmitting a Narrowband Physical Broadcast Channel (NPBCH), a Narrowband Primary Synchronization Signal (NPSS), a Narrowband Secondary Synchronization Signal (NSSS) and SIB1-NB as time domain transmission units for solving collisions by a delay method, time domain transmission units for transmitting SIBs other than SIB1-NB as specific time domain transmission units, and time domain transmission units as subframes as examples: when a discarding manner is adopted for all specific time domain transmission units, the time domain transmission unit that can be used for transmitting the preset signal is a time domain transmission unit without padding within the range of time T1 in fig. 3A; when the delay scheme is applied to all specific time domain transmission units, the time domain transmission units that can be used for transmitting the preset signal are time domain transmission units without padding within the range of time T2 in fig. 3B.

Referring to fig. 3A and 3B, when a discarding manner is adopted for all specific time domain transmission units, the number of time domain transmission units that can be used for transmitting the preset signal is only 6 time domain transmission units, the number of time domain transmission units that can be used for transmitting the preset signal is small, and there is a problem that the applicable coverage of the signal is small. When all the specific time domain transmission units adopt the delay mode, the time span of the time domain transmission units which can be used for transmitting the preset signal is large, the maximum window length of the receiving end for receiving the preset signal is 74 time domain transmission units, the maximum window length of the receiving end for receiving the preset signal is large, and the problem that the power consumption of the receiving end is large exists. That is, in the prior art, regardless of the specific situation, a processing method of a discarding method or a delaying method is adopted, which may cause a problem that the power consumption of the receiving end is large or the applicable coverage of the signal is small.

It can be seen that all subframes of

radio frames

1 and 2 and the first 9 subframes of radio frame 3 in fig. 3A are candidate time domain transmission units of the default signal. In fig. 3B, all subframes of radio frames 1 to 7 and the first 4 subframes of radio frame 8 are candidate time domain transmission units of the default signal. It should be noted that, in fig. 3A and fig. 3B, the collision resolution method when the time domain transmission unit for transmitting the SIB other than SIB1-NB collides with the candidate time domain transmission unit for the specific time domain transmission unit is mainly discussed, and the collision resolution method when the time domain transmission unit for transmitting NPBCH, NPSS, NSSS, and SIB1-NB collides with the candidate time domain transmission unit may be fixed as the delay method.

It should be noted that, in fig. 3A and fig. 3B, the time domain transmission unit is taken as a subframe, the maximum duration is 20 subframes, one radio frame includes 10 subframes, and the start position of the preset signal is the first subframe of the radio frame 1.

The technical solution of the present application will be described in detail below with specific examples. 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.

Fig. 4 is a flowchart of a communication method according to an embodiment of the present application, where an execution main body of the embodiment may be a communication device. As shown in fig. 4, the method of this embodiment may include:

step 401, acquiring a first threshold and a starting position of a preset signal.

In this step, the first threshold is used to determine a collision resolution manner when the candidate time domain transmission unit of the preset signal collides with a specific time domain transmission unit. The starting position of the preset signal may be obtained through configuration, or may also be agreed by a protocol, which is not limited in this application. The first threshold may be obtained through configuration or may be agreed, and this application does not limit this. When the first threshold is obtained through configuration and the communication device is a base station, the method of this embodiment may further include: and sending indication information to a receiving end, wherein the indication information is used for indicating the first threshold value.

When the first threshold is obtained through configuration and the communication device is a terminal, the method of this embodiment may further include: and receiving indication information sent by a sending end, wherein the indication information is used for indicating the first threshold value. Optionally, the indication information may include the first threshold, or the indication information may include a proportional relationship between the first threshold and a maximum duration of the preset signal.

For example, the maximum duration is 20, when the first threshold is 5, the indication information may indicate 4, and the receiving end may obtain the first threshold 5 by dividing 20 by 4.

For another example, the maximum duration is 20, and when the first threshold is 5, the indication information may indicate

The receiving end can multiply by 20

A first threshold value 5 is obtained.

The conflict resolution means may include a delay means, a discard means, or a discard means. For the receiving end, the abandoning mode may be specifically understood as abandoning receiving the preset signal, that is, not receiving the preset signal; for the transmitting end, the abandoning mode may be understood as abandoning the transmission of the preset signal, i.e. not transmitting the preset signal. Optionally, it may be determined, according to the first threshold, that a delay manner is adopted for all candidate time domain transmission units that collide with a specific time domain transmission unit; or, it may be determined, according to the first threshold, that a discarding manner is adopted for all candidate time domain transmission units that collide with a specific time domain transmission unit; or, it may be determined, according to the first threshold, that a partial delay and partial discard manner is adopted for all candidate time domain transmission units that collide with a specific time domain transmission unit; alternatively, it may be determined to refrain from transmitting or receiving a preset signal according to the first threshold.

Here, the first threshold is used to determine a collision resolution manner when the candidate time domain transmission unit of the preset signal collides with the specific time domain transmission unit, so that collision resolution manners of different specific time domain transmission units can be determined according to the first threshold, and a problem that a receiving end may consume more power or a signal may have a smaller applicable coverage range when a discarding manner or a delaying manner is adopted regardless of specific situations is avoided.

Step 402, starting from the starting position, sending or receiving the preset signal according to the first threshold value.

In this step, when sending or receiving a preset signal, a discarding manner or a delaying manner is not used regardless of specific situations, but the preset signal is sent or received according to a first threshold value of a collision resolution manner used for determining when a candidate time domain transmission unit of the preset signal collides with a specific time domain transmission unit.

Depending on the specific role of the first threshold, optionally, the preset signal may be specifically transmitted or received according to the first threshold from the starting position in any one of the following manners 1 to 3.

Mode 1

Step 402 may specifically include: starting from the starting position, a first collision resolution is adopted for the mth specific time domain transmission unit, wherein m is an integer which is greater than 0 and less than or equal to the first threshold value.

Further optionally, when, starting from the starting position, there is an nth specific time domain transmission unit, where n is an integer greater than the first threshold, step 402 may further include: and sending or receiving the preset signal by adopting a second conflict resolution mode for the nth specific time domain transmission unit.

Optionally, the first conflict resolution mode is a delay mode, and the second conflict resolution mode is a discard mode; or, the first conflict resolution mode is a discarding mode, and the second conflict resolution mode is a delaying mode.

In the method 1, by adopting the first conflict solution for the mth specific time domain transmission unit and the second conflict solution for the nth specific time domain transmission unit, when the number of the conflicting specific time domain transmissions is large, compromise between the two conflict solution methods can be realized, and the problem that the power consumption of the receiving end is large or the applicable coverage range of the signal is small due to the fact that the specific situation is not considered and a discarding method or a delaying method is adopted is avoided.

It should be noted that the number of the specific time domain transmission units in conflict may be less than or equal to the first threshold, and the first conflict resolution manner is adopted for all the specific time domain transmission units. Because the number of the conflicting specific time domain transmission units is small, it can be considered that there is no problem that the power consumption of the receiving end is large or the applicable coverage of the signal is small because the specific situation is not considered for the specific time domain transmission units and a delay manner or a discard manner is adopted.

For example, assuming that the maximum duration is 20 time domain transmission units, the function and the starting position of each time domain transmission unit are as shown in fig. 5, the time domain transmission unit transmitting the SIB other than the SIB1-NB is the specific time domain transmission unit, the first threshold is 5, the first collision resolution manner is the delay manner, and the second collision resolution manner is the discard manner, then starting from the starting position, the first collision resolution manner is adopted for the mth specific time domain transmission unit, the second collision resolution manner is adopted for the nth specific time domain transmission unit, and when the preset signal is transmitted or received, the time domain transmission unit that can be used for transmitting the preset signal is the time domain transmission unit without padding within the time T3 as shown in fig. 5.

As can be seen from fig. 5, in the mode 1, the number of the time domain transmission units that can be used for transmitting the preset signal is 9 time domain transmission units, and compared with the number of the time domain transmission units that can be used for transmitting the preset signal shown in fig. 3A being 6 time domain transmission units, the number of the time domain transmission units that can be used for transmitting the preset signal is increased, so that the problem that the applicable coverage of the signal is small is solved.

As can be seen from fig. 5, in the method 1, the maximum window length of the receiving end for receiving the preset signal is 35 time domain transmission units, and compared with the maximum window length of the receiving end for receiving the preset signal shown in fig. 3B which is 74 time domain transmission units, the maximum window length for receiving the preset signal is reduced, so that the problem of large power consumption of the receiving end is solved.

It should be noted that, in fig. 5, the time domain transmission unit is taken as a subframe, the maximum duration is 20 subframes, one radio frame includes 10 subframes, and the starting position of the preset signal is the first subframe of the radio frame 1.

Mode 2

Step 402 may specifically include: determining the maximum window length of the received preset signal when a delay mode is adopted for the specific time domain transmission unit from the starting position according to the maximum duration of the preset signal;

In the method 2, if the maximum window length of the receiving end receiving the preset signal is increased by a large amount due to the delay method, a discarding method is adopted, so that the problem of large power consumption of the receiving end is avoided.

Further, if the difference degree is smaller than the first threshold, the preset signal is sent or received in a delay manner from the starting position. Here, if the delay mode does not cause the maximum window length of the receiving end for receiving the preset signal to increase greatly, the delay mode is adopted, so that the power consumption of the receiving end is ensured within a reasonable range, and meanwhile, the applicable coverage range of the signal can be ensured.

Optionally, the second threshold is associated with the maximum duration, and specifically may be: the second threshold is equal to the window length corresponding to the maximum duration; or, determining the second threshold according to the maximum duration. Further optionally, the determining the second threshold according to the maximum duration may include: and when a discarding mode is adopted for the specific time domain transmission unit from the starting position, the maximum window length of the preset signal is received and determined according to the maximum duration of the preset signal, and the maximum window length is used as the second threshold.

Optionally, the difference between the maximum window length and the second threshold may be the difference between the maximum window length and the second threshold.

For example, assuming that the maximum duration is 20 time domain transmission units, the second threshold is equal to the window length 20 corresponding to the maximum duration, the maximum window length is 74, and the difference between the maximum window length and the second threshold is 74-20, which is 54, when the first threshold is equal to 20, 54 is greater than 20, and an add drop (drop) manner is adopted; when the first threshold is equal to 60, 54 is less than 60, and an adopt postdone is used.

Mode 3

Step 402 may specifically include: judging whether the number of the specific time domain transmission units in the target time length range is less than or equal to the first threshold value from the starting position; the target duration is associated with a maximum duration of the preset signal;

In the method 3, if the number of the specific time domain transmission units in the target time length range is small, the preset signal is sent or received from the start position, so that the specific time domain transmission units cannot greatly affect the number of the time domain transmission units which can be used for transmitting the preset signal and the maximum window length of the preset signal received by the receiving end, and therefore the problem that the applicable coverage range of the signal is small due to signal collision with the specific time domain transmission units or the power consumption of the receiving end is large is solved.

It should be noted that, in the method 3, the collision resolution method of a specific time domain transmission unit in the process of transmitting or receiving the preset signal from the starting position is not limited. For example, a delayed mode or a dropped mode may be employed.

Further, if the number of the specific time domain transmission units in the target time duration range is greater than the first threshold from the starting position, the preset signal is not sent or received (it may be understood that the preset signal is abandoned to be sent or received this time). Here, if the number of the specific time domain transmission units in the target time duration range is large, the preset signal is not sent or received, so that the influence on sending or receiving the preset signal when the number of the specific time domain transmission units is large is avoided, and the problem that the applicable coverage range of the signal is small or the power consumption of the receiving end is large due to the collision with the specific time domain transmission units is solved.

Optionally, the target duration is associated with the maximum duration, and specifically may be: the target duration is equal to the maximum duration; or, determining the target duration according to the maximum duration. Further optionally, the determining the target duration according to the maximum duration may include: and taking the time length corresponding to the maximum window length of the received preset signal when the specific time domain transmission unit is discarded from the starting position determined according to the maximum duration as the target time length.

In the embodiment shown in fig. 6, the specific manner of transmitting or receiving the preset signal according to the first threshold from the start position should be consistent between the receiving end and the transmitting end, which are both communication ends. For example, the sending end sends the preset signal according to the first threshold in the above manner, and the receiving end may also receive the preset signal according to the first threshold in the above manner.

In this embodiment, a first threshold and an initial position of a preset signal are obtained, where the first threshold is used to determine a collision resolution mode when a candidate time domain transmission unit of the preset signal collides with a specific time domain transmission unit, and the preset signal is sent or received according to the first threshold from the initial position, so that collision resolution modes of different specific time domain transmission units can be determined according to the first threshold, thereby avoiding a problem that a receiving end may consume more power or a signal may have a smaller coverage when a discarding mode or a delaying mode is adopted regardless of specific situations.

Fig. 6 is a flowchart of a communication method according to another embodiment of the present application, where an execution subject of the embodiment may be a communication device. As shown in fig. 6, the method of this embodiment may include:

step 601, judging whether a specific time domain transmission unit exists in a target time length range from the initial position of a preset signal.

In this step, the target duration is associated with a maximum duration of the preset signal. For example, as shown in fig. 2B, assuming that the target duration is a duration corresponding to 7 time domain transmission units, it may be determined that a specific time domain transmission unit exists in the target duration range. If the specific time domain transmission unit does not exist in the target duration range from the start position, step 602 is executed.

Further, if the specific time domain transmission unit exists in the target duration range from the starting position, the process is ended, or step 603 is executed.

It should be noted that, regarding the specific manner of obtaining the start position, reference may be made to the related description in step 401, and details are not described herein again.

Step 602, starting from the starting position, sending or receiving the preset signal.

In this step, the collision resolution manner of the specific time domain transmission unit in the process of transmitting or receiving the preset signal from the starting position is not limited. For example, a delayed mode or a dropped mode may be employed.

Step 603, not sending or receiving the preset signal.

In this step, the step of not sending or receiving the preset signal may be understood as abandoning sending or receiving the preset signal this time.

In this embodiment, whether a specific time domain transmission unit exists in a target time length range from an initial position of a preset signal is determined, and if the specific time domain transmission unit does not exist in the target time length range from the initial position, the preset signal is sent or received from the initial position, so that the number of time domain transmission units which can be used for transmitting the preset signal and the maximum window length of the preset signal received by a receiving end can be prevented from being affected by the specific time domain transmission unit, and the problem that the applicable coverage range is small or the power consumption of the receiving end is large due to signal collision with the specific time domain transmission unit is solved.
