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, taking a transmitting end as a base station and a receiving end as a terminal as an example, subframes of the base station for transmitting a primary synchronization signal (primary synchronization signal, PSS), a secondary synchronization signal (subsidiary synchronization signal, SSS), a physical broadcast channel (physical broadcast channel, PBCH), a system message (system information, SI) and the like to the terminal are usually protocol-agreed subframes, and when a transmission time window of other signals to be transmitted by the base station includes subframes for transmitting PSS, SSS, PBCH, SI and the like, that is, a collision with subframes for transmitting PSS, SSS, PBCH, SI and the like, the collision can be resolved in any one of the following two manners: firstly, a delay (postfine) mode expands a time window, wherein the number of subframes in the time window for transmitting other signals is a preset number; second, the drop (drop) method does not expand the time window, and the number of subframes available for transmitting other signals in the time window is smaller than a predetermined number.

However, in the prior art, the power consumption of the receiving end may be larger, or the coverage area of the signal may be smaller.

In the above scheme, if the delay mode is adopted to cause the maximum window length of the preset signal to be greatly increased, the discarding mode is adopted, so that the problem of high power consumption of the receiving end is avoided.

In one possible implementation, the method further comprises:

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

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

In the above scheme, if the number of the specific time domain transmission units in the target duration range is smaller, the preset signals are sent or received from the starting position, so that the specific time domain transmission units can be ensured not to have larger influence on the number of the time domain transmission units which can be used for transmitting the preset signals and the maximum window length of the preset signals received by the receiving end, and the problems that the applicable coverage range of the signals caused by signal conflict with the specific time domain transmission units is smaller or the power consumption of the receiving end is larger are solved.

In one possible implementation, the method further comprises:

And if the number of the specific time domain transmission units in the target time length range is greater 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 more, the preset signals are not transmitted or received, so that the influence on transmitting or receiving the preset signals when the number of the specific time domain transmission units is more is avoided, and the problems that the applicable coverage range of signals caused by conflict with the specific time domain transmission units is smaller, or the power consumption of a receiving end is larger are solved.

Detailed Description

Fig. 1A is a schematic view of an application scenario in the embodiment of the present application, as shown in fig. 1A, the application scenario in the embodiment may include: a transmitting end and a receiving end. Wherein the transmitting end and the receiving end may be collectively referred to as a communication device. The communication device may acquire a starting position of a preset signal and a first threshold, where the first threshold is used to determine a conflict resolution mode when a candidate time domain transmission unit of the preset signal conflicts 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 transmitting end, the preset signal may specifically be sent according to the first threshold, starting at the starting position; for the receiving end, the starting position may be specifically the starting position, and the preset signal is received according to the first threshold value. The transmitting side and the receiving side are relative concepts, and when the device 1 transmits to the device 2, the device 1 may be regarded as the transmitting side, and the device 2 may be regarded as the receiving side. When the device 2 transmits to the device 1, the device 2 may be regarded as a transmitting end, and the device 1 may be regarded as a receiving end.

It should be noted that the embodiments of the present application may be applied to any communication system involving a time domain transmission unit, such as a long term evolution (1ong term evolution,LTE) system, a narrowband internet of things (narrow band internet of things, NB-IoT), a 5G New Radio (NR) system, a global system for mobile communications (global system for mobile communication, GSM), a mobile communication system (universal mobile telecommunications system, UMTS), a code division multiple access (code division multiple access, CDMA) system, and a new network system. For example, as shown in fig. 1B, the communication system provided in this embodiment may include: base Station (BS), user Equipment (UE) 1-UE6. When the base station is used as a transmitting end, UE1, UE2, UE3 and UE5 may be used as receiving ends corresponding to the base station. When the base station is used as a receiving end, UE1, UE2, UE3 and UE5 may be used as transmitting ends corresponding to the base station. When UE5 is used as a receiving end, UE4 and UE6 may be used as corresponding transmitting ends of UE 5. When UE5 is used as a transmitting end, UE4 and UE6 may be used as corresponding receiving ends of UE 5.

The terminal, which may also be referred to as a user equipment, may include, but is not limited to, a smart phone (such as 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 (mobile internet devices, MID), or an internet device such as a wearable smart device, etc.

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)) may be referred to as a 5G base station (gndeb, gNB), or a relay station, or a vehicle 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 (public land mobile network, PLMN) network, or the like, which is not limited in this application.

Alternatively, the specific time domain transmission unit may be specifically a time domain transmission unit fixed 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 message block (system information block, SIB) x, x being an integer greater than 1. Further optionally, in the narrowband internet of things, a time domain transmission unit for transmitting other system message blocks besides SIB1-NB is fixed, for example, SIB2-NB, SIB3-NB, and the like.

Alternatively, 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 the sending end controls to send through the starting position and the maximum duration. Further alternatively, 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 transmitting or receiving the preset signal, and in particular, the candidate time domain transmission unit may be associated with a starting position, a maximum duration of the preset signal. The candidate time domain transmission unit colliding with the specific time domain transmission unit may be understood as the candidate time domain transmission unit being the specific time domain transmission unit. Wherein the maximum duration may be represented by a time, e.g., 10 milliseconds (ms); alternatively, the number of time domain transmission units may be represented, for example, by 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 that the maximum duration is 10 time domain transmission units, the following description is made with reference to fig. 2A to 2C for the delay mode and the discard mode:

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 a time domain transmission unit within the range of the maximum duration T as in fig. 2A.

When two point-filled time domain transmission units in the candidate time domain transmission units are specific time domain transmission units and a delay mode is adopted for the two point-filled specific time domain transmission units, the time domain transmission units which can be used for transmitting the preset signal are time domain transmission units which are not filled in a range of T+T 'as shown in fig. 2B, wherein T' is the duration of the two specific time domain transmission units.

When two point-filled time domain transmission units in the candidate time domain transmission units are specific time domain transmission units and a discarding mode is adopted for the two point-filled time domain transmission units, the time domain transmission units which can be used for transmitting the preset signal are time domain transmission units which are not filled in the range T as shown in fig. 2C.

As can be seen from fig. 2A to fig. 2C, for the time domain transmission units that collide, resolving the collision by using a delay method does not affect the number of time domain transmission units that can be used to transmit the preset signal. However, resolving the conflict by the discard method affects the number of time domain transmission units that can be used for transmitting the preset signal, that is, the sum of the number of time domain transmission units that can be used for transmitting the preset signal and the number of specific time domain transmission units that resolve the conflict by the discard 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 lattice may represent a time domain transmission unit.

Taking a communication system as a narrowband internet of things (narrow band 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 (narrowband physical broadcast channel, NPBCH), a narrowband primary synchronization signal (narrowband primary synchronization signal, NPSS), a narrowband secondary synchronization signal (narrowband subsidiary synchronization signal, NSSS) and an SIB1-NB as fixed time domain transmission units for resolving conflicts in a delay mode, time domain transmission units for transmitting SIBs other than the SIB1-NB as specific time domain transmission units, wherein the time domain transmission units are subframes as examples: when a discarding manner is adopted for 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 that are not filled within the time T1 range as in fig. 3A; when a delay mode is adopted for 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 that are not filled in the time T2 range as in fig. 3B.

Referring to fig. 3A and 3B, when a discard mode 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 less, and there is a problem that the applicable coverage area of the signal is smaller. When a delay mode is adopted for all specific time domain transmission units, the time span of the time domain transmission units which can be used for transmitting the preset signals is larger, the maximum window length of the receiving end for receiving the preset signals is 74 time domain transmission units, the maximum window length of the receiving end for receiving the preset signals is larger, and the problem of larger power consumption of the receiving end exists. That is, in the prior art, a processing method of a discard method or a delay method is adopted regardless of the specific situation, which may result in a large power consumption of the receiving end or a small coverage area for the signal.

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

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 starting position of the preset signal is taken as the first subframe of the radio frame 1 as an example.

The technical scheme of the present application is described in detail below with specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.

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

in step 401, a first threshold and a start position of a preset signal are obtained.

In this step, the first threshold is used to determine a collision resolution mode when the candidate time domain transmission unit of the preset signal collides with the specific time domain transmission unit. The starting position of the preset signal may be obtained through configuration, or may be agreed by a protocol, which is not limited in this application. The first threshold may be obtained through configuration, or may be agreed by a protocol, which is not limited in this application. 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 the indication information may indicate when the first threshold is 5The receiving end can multiply by +.>A first threshold value 5 is obtained.

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

Here, the first threshold is used to determine a conflict resolution mode when the candidate time domain transmission unit of the preset signal conflicts with the specific time domain transmission unit, so that the conflict resolution modes of different specific time domain transmission units can be determined according to the first threshold, and the problem that when a processing mode of a discarding mode or a delay mode is adopted regardless of specific conditions, the power consumption of a receiving end is possibly larger, or the applicable coverage range of the signal is smaller 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 the preset signal is transmitted or received, the preset signal is transmitted or received according to a first threshold value of a collision resolution method when the candidate time domain transmission unit for determining the preset signal collides with the specific time domain transmission unit, instead of adopting a discarding method or a delay method regardless of specific conditions.

Depending on the specific role of the first threshold, the preset signal may be optionally sent or received according to the first threshold from the start position by any one of the following modes 1 to 3.

Mode 1

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

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

Optionally, the first conflict resolution mode is a delay mode, and the second conflict resolution mode is a discard mode; alternatively, the first conflict resolution mode is a discard mode, and the second conflict resolution mode is a delay mode.

In the mode 1, by adopting the first collision resolution mode for the mth specific time domain transmission unit and adopting the second collision resolution mode for the nth specific time domain transmission unit, when the number of specific time domain transmissions of the collision is large, the two collision resolution modes are balanced, so that the problem that the power consumption of the receiving end is large or the applicable coverage range of the signal is small when a discarding mode or a delay mode is adopted regardless of specific conditions is avoided.

It should be noted that the number of colliding specific time domain transmission units may be less than or equal to the first threshold, and the first collision resolution method is adopted for all specific time domain transmission units. Because the number of the conflicting specific time domain transmission units is smaller, the problem that the power consumption of the receiving end is larger or the applicable coverage of the signal is smaller due to the fact that a delay mode or a discarding mode is adopted for the specific time domain transmission units without considering specific conditions can be considered.

For example, assuming that the maximum duration is 20 time domain transmission units, the action and the starting position of each time domain transmission unit are shown in fig. 5, the time domain transmission units for transmitting SIBs other than SIB1-NB are specific time domain transmission units, the first collision resolution mode is a delay mode, the second collision resolution mode is a discard mode, starting from the starting position, the first collision resolution mode is adopted for the mth specific time domain transmission unit, the second collision resolution mode is adopted for the nth specific time domain transmission unit, and when the preset signal is transmitted or received, the time domain transmission units that can be used for transmitting the preset signal are time domain transmission units that are not filled in the time T3 range in fig. 5.

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

As can be seen from fig. 5, in the case of mode 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 of the receiving end for receiving the preset signal is reduced, thereby solving the problem of larger power consumption of the receiving end.

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 taken as the first subframe of the radio frame 1 as an example.

Mode 2

Step 402 may specifically include: determining a maximum window length of the 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 mode 2, if the delay mode is adopted, the maximum window length of the preset signal received by the receiving end is increased greatly, and then the discarding mode is adopted, so that the problem of high 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 mode from the initial position. Here, if the delay mode does not cause the maximum window length of the receiving end for receiving the preset signal to be increased much, the delay mode is adopted, so that the power consumption of the receiving end is ensured to be within a reasonable range, and meanwhile, the applicable coverage range of the signal is ensured.

Optionally, the second threshold is associated with the maximum duration, which may be specifically: 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 receiving the maximum window length of the preset signal as the second threshold value when the discarding mode is adopted for the specific time domain transmission unit from the starting position according to the maximum duration of the preset signal.

Alternatively, the degree of 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=54, when the first threshold is equal to 20, 54 is greater than 20, and a drop (adopt drop) mode is adopted; when the first threshold is equal to 60, 54 is less than 60, and a delay (adopt postpon) mode is adopted.

Mode 3

Step 402 may specifically include: judging whether the number of the specific time domain transmission units in the target duration range is smaller 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 mode 3, if the number of specific time domain transmission units in the target duration range is smaller, the preset signals are sent or received from the starting position, so that it can be ensured that the specific time domain transmission units do not have a larger influence on the number of time domain transmission units capable of transmitting the preset signals and the maximum window length of the preset signals received by the receiving end, and therefore the problems of smaller applicable coverage range of signals caused by signal conflict with the specific time domain transmission units or larger power consumption of the receiving end are solved.

Here, in the method 3, the collision resolution method of the specific time domain transmission unit in the process of transmitting or receiving the preset signal from the start position is not limited. For example, a delay mode or a discard mode may be employed.

Further, if the number of the specific time domain transmission units in the target time duration range from the starting position is greater than the first threshold, the preset signal is not transmitted or received (which may be understood as discarding the transmission or the reception of the preset signal). Here, if the number of the specific time domain transmission units in the target duration range is more, the preset signal is not transmitted or received, so that the influence on transmitting or receiving the preset signal when the number of the specific time domain transmission units is more is avoided, and the problems that the applicable coverage range of the signal is smaller or the power consumption of the receiving end is larger due to the conflict with the specific time domain transmission units are solved.

Optionally, the target duration is associated with the maximum duration, which may specifically 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 receiving the duration corresponding to the maximum window length of the preset signal as the target duration when the discarding mode is adopted for the specific time domain transmission unit from the starting position according to the maximum duration.

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

In this embodiment, a first threshold value and a starting position of a preset signal are obtained, where the first threshold value 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 value from the starting position, so that the collision resolution modes of different specific time domain transmission units can be determined according to the first threshold value, and the problem that when a discarding mode or a delay mode is adopted regardless of specific situations, the power consumption of a receiving end is possibly larger, or the applicable coverage area of the signal is smaller is avoided.

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

Step 601, determining whether a specific time domain transmission unit exists in the target duration range from the start position of the 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 time length is a time length corresponding to 7 time domain transmission units, it may be determined that a specific time domain transmission unit exists in the target time length range. If the specific time domain transmission unit does not exist in the target time duration range from the starting position, step 602 is performed.

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

It should be noted that, for a specific manner of acquiring the start position, reference may be made to the description of step 401, which is not repeated herein.

Step 602, starting to send or receive the preset signal from the starting position.

In this step, the conflict resolution method 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 delay mode or a discard mode may be employed.

Step 603, not sending or receiving the preset signal.

In this step, the preset signal is not transmitted or received, which can be understood as giving up the transmission or reception of the preset signal.

In this embodiment, by determining whether a specific time domain transmission unit exists in a target time length range from a start position of a preset signal, if the specific time domain transmission unit does not exist in the target time length range from the start position, the preset signal is sent or received from the start position, so that it is ensured that the specific time domain transmission unit does not affect the number of time domain transmission units that can be used to transmit the preset signal and the maximum window length of a receiving end for receiving the preset signal, and therefore, the problem that the applicable coverage area caused by signal collision with the specific time domain transmission unit is smaller or the power consumption of the receiving end is larger is solved.
