The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the strength of the pressure from the change in capacitance.

The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message.

Example 1

The wireless communication module 160 shown in fig. 1 may specifically include a first communication unit and a second communication unit, and the processor 110 may include a main control unit. The problem that a time domain conflict may exist between a first communication unit and a second communication unit is a problem to be solved by the embodiments of the present application.

Based on the above, an embodiment of the present application provides a method for solving coexistence interference, where the principle of the method is as follows: the first communication unit and the second communication unit respectively inform the main control unit of the occupation condition of the time unit. And the main control unit judges whether the time domain occupation conditions of the first communication unit and the second communication unit conflict. And if the two conflict, the main control unit coordinates the two. For example, time units used for communication are newly allocated to both, or conflicting time units are allocated to communication units with higher traffic priority, and the like, without limitation.

As shown in fig. 2, an embodiment of the present invention provides a process of a method for solving coexistence interference, where a main control unit in the process may be specifically located in the processor 110 in fig. 1, and a first communication unit and a second communication unit may be specifically located in the wireless communication module 160 in fig. 1, and the process includes:

s200: the first communication unit determines a first time unit occupied by communication and sends a first indication to a main control unit, wherein the first indication is used for indicating the first time unit.

For example, the master control unit may send a clock synchronization signal to the first communication unit. Accordingly, the first communication unit receives the clock synchronization signal. The clock synchronization signal may also be referred to as a synchronization signal, a synchronization clock signal, and the like, without limitation. The first communication unit determines one or more time units based on the clock synchronization signal. In the one or more time units, a first time unit is determined. For example, the master control unit may periodically transmit the clock synchronization signal with a period of 1 s. The first communication unit increases the manner from the start point to the time domain by 1s with the start time of receiving the clock synchronization signal as the start point. And dividing the 1s into a plurality of time units according to the preset duration of the time unit. Finally, a first time unit for communication, or communication occupancy, is determined from the plurality of time units.

S201: and the second communication unit determines a second time unit occupied by communication and sends a second instruction to the main control unit, wherein the second instruction is used for indicating the second time unit.

For example, the master unit may send a clock synchronization signal to the second communication unit. For the clock synchronization signal, reference may be made to the above description of S200, and a description thereof will not be provided. Correspondingly, the second communication unit receives the clock synchronization signal, determines a plurality of time units according to the clock synchronization signal, and determines the second time unit occupied or used for communication in the plurality of time units. Regarding the process of the second communication unit determining the second time unit, the process of the first communication unit determining the first time unit is similar to the above S200, and will not be described here.

S202: the master control unit receives the first indication and the second indication, and reallocates the occupiable time units for the first communication unit and/or the second communication unit when the first time unit indicated by the first indication and the second time unit indicated by the second indication overlap, and notifies the first communication unit and/or the second communication unit of the reallocated time units.

For example, after receiving the first indication and the second indication, the main control unit may determine the first time unit according to the first indication, and determine the second time unit according to the second indication. The main control unit judges whether the first time unit and the second time unit have overlap, and the overlap can be complete overlap or partial overlap. For example, the first time unit includes N time slots, where N is an integer greater than 0, and the second time unit includes M time slots, where M is an integer greater than 0. The first time unit overlaps the second time unit, and specifically, at least one time slot included in the first time unit overlaps at least one time slot included in the second time unit. If there is an overlap between the first time unit and the second time unit, the above step of S202 is performed. Accordingly, the first time unit and/or the second time unit may communicate using the reallocated time units. If there is no overlap between the first time unit and the second time unit, no operation may be performed, or the first time unit and/or the second time unit may be notified and communication may be performed according to the determined time unit.

In one embodiment, the master control unit may reallocate the time units that may be occupied for the first communication unit and/or the second communication unit according to the service priority. For example, when there is an overlap between a first time unit indicated by the first indication and a second time unit indicated by the second indication, the overlapped time units are referred to as overlapped time units. When the service priority of the first communication unit is higher than that of the second communication unit, the main control unit may reallocate a third time unit that may be occupied by communication for the second communication unit, and the third time unit is not overlapped with the first time unit. The master control unit may notify the second communication unit of the third time unit. Correspondingly, the second communication unit can utilize or occupy the third time unit for communication, and the first communication unit can utilize or occupy the first time unit for communication, so that the time domain occupation of the second communication unit and the time domain occupation of the first communication unit are ensured not to conflict. When the main control unit allocates the third time unit to the second communication unit, the following method may be adopted: the main control unit determines the overlapping time unit of the two units, and the main control unit removes the overlapping time unit part from the second time unit originally occupied by the second communication unit to form a third time unit. Or, the main control unit can determine a first time unit occupied by the first communication unit for communication, and reallocate a third time unit for the second communication unit based on the first time unit, wherein the allocation principle is to ensure that the third time unit and the first time unit are not overlapped completely.

And when the service priority of the second communication unit is higher than that of the first communication unit, the main control unit can reallocate a fourth time unit which can be occupied by communication for the first communication unit, and the fourth time unit is not overlapped with the second time unit. The master unit may notify the fourth time unit to the first communication unit. Accordingly, the first communication unit may communicate using the fourth time unit, and the second communication unit may communicate using the second time unit. For example, the master unit may determine an overlap time cell where the two overlap. The main control unit removes the overlapping time unit part from the first time unit originally occupied by the first communication unit to form a fourth time unit. Or, the main control unit can determine a second time unit occupied by the second communication unit, and reallocate the fourth time unit for the first communication unit based on the second time unit, wherein the second time unit and the fourth time unit are not overlapped completely.

It should be understood that in the embodiments of the present application, words such as "first", "second", etc. are used for distinguishing between the descriptions, and are not to be construed as indicating or implying relative importance, nor order. The main control unit may be an independent controller in the electronic device, or may be a main control unit in a single product, and the like, without limitation. The communication unit, which may also be referred to as a wireless unit, may be a wireless functional device with independent operation capabilities, such as a WIFI functional device, a BT functional device, a UWB functional device. Alternatively, the communication unit may be a wireless subsystem in a single product, and the like, without limitation. The time unit is a time domain unit for data transmission, and may include a radio frame (radioframe), a subframe (subframe), a slot (slot), a mini-slot (mini-slot), and a time domain symbol (symbol), which is not limited. For example, in a 5G New Radio (NR), one radio frame may include 10 subframes, one subframe may include one or more slots, and specifically, how many slots one subframe includes are related to a subcarrier interval.

Based on the method for solving interference collision provided in fig. 2, as shown in fig. 3, an application scenario is provided, which is only an illustrative example and is not a limitation to the embodiment of the present application. As shown in fig. 3, a main control unit and a plurality of wireless units are included in this scenario. In fig. 3, a plurality of wireless units including Wi-Fi, Bluetooth (BT), Global Navigation Satellite System (GNSS), Network Access Delay (NAD), Ultra Wide Band (UWB), millimeter wave (mmWave), vehicle networking (V2X), and others are exemplified. The main control unit shown in fig. 3 may be specifically the main control unit in the process shown in fig. 2, and the plurality of wireless units shown in fig. 3 may specifically include the first wireless unit and the second wireless unit in the process shown in fig. 2, or may be described that the first wireless unit and the second wireless unit in the process shown in fig. 2 may be specifically any two wireless units in the plurality of wireless units shown in fig. 3.

The main control unit may be an independent controller, or may be a main control unit of a single product, without limitation. The wireless unit may be a wireless-capable device having independent operation capabilities, such as a WI-FI-capable device, a BT-capable device, and a UWB-capable device. Or may be a wireless subsystem in a single product, without limitation.

Still referring to fig. 3, in the embodiment of the present application, two signal lines, namely, a signal line ① and a signal line ②, are mainly included, where the signal line ① is a hardware synchronization signal line for outputting a clock synchronization signal, the clock synchronization signal may be a 1Hz pulse-per-second digital signal, and the signal line is physically connected to all wireless units that need to solve the coexisting interference data.

In the embodiment of the application, the main control unit can provide hardware synchronization clock signals and software service priority judgment, the wireless unit feeds back the occupation situation based on the hardware synchronization clock signals, and uses the allowed time slot to process services according to the feedback of the main control unit. The master control unit outputs a synchronization clock signal to which the other wireless units are connected and based on this signal as a synchronization reference. Each wireless unit divides the time slot information based on the synchronous reference and matches the time slots which need to be occupied by the wireless unit. And transmits the information to the master control unit through the existing traffic channel. The main control unit combines the current service priority to configure the occupiable time slot information of each wireless unit and transmits the information to the corresponding wireless unit through the service channel.

In the embodiment of the present application, as shown in fig. 4, a first communication unit is taken as a WIFI unit, and a second communication unit is taken as a BT unit for example, so as to describe the embodiment. The main control unit can send clock synchronization signals to the WIFI unit and the BT unit, the WIFI unit and the BT unit can determine reference time slots based on the clock synchronization signals, and the WIFI unit and the BT unit respectively determine the conditions of occupying the time slots according to the reference time slots. For example, as shown in fig. 7, the slot occupancy of the WIFI unit may be: slot 0, slot 1, slot 2, slot 6, slot 7, slot 8, and slot 9 in band 1. The slot occupancy of the BT unit may be: slot 1, slot 2, slot 3, slot 4, and slot 5 in band 1. It is understood that, in the embodiment of the present application, the time slot division of different frequency bands may be the same or different, and is not limited. The method provided by the embodiment of the application can be suitable for time slot conflicts of the same frequency band, time slot conflicts of different frequency bands and the like, and is not limited. In the embodiment of the present application, a time slot collision of the same frequency band is taken as an example for explanation.

After determining the time slot occupation conditions of the WIFI unit and the BT unit, the main control unit can combine the current service scene to allocate time slots for the WIFI unit or the BT unit to be reallocated. For example, as shown in fig. 8, considering that the priority of BT is higher than that of WIFI, WIFI may be required to disable slot 1 and slot 2 to transmit traffic data. In a scene that WIFI and BT coexist, the connection rate of BT can be effectively improved.

In this embodiment of the present application, a centralized processing manner may be adopted, all wireless devices may be synchronized by the clock synchronization signal, and each wireless device divides a time slot based on the clock synchronization signal to express a time domain signal of a frequency band that needs to be occupied. The main control unit feeds back the allowed time slots by combining the application conditions of a plurality of wireless devices, the service priority and the like, and avoids the interference problem through the centralized management of the main control. Meanwhile, by adopting the scheme of the embodiment of the application, the complexity can be reduced in hardware, and compared with the scheme of processing the coexistence of the wireless devices through 3-4 hard wires in the prior art, the method and the device for processing the coexistence of the wireless devices have the advantages of being simple in structure, convenient to use and low in cost. By adopting the scheme of the application, only 1 hard wire is needed, and the hard wire design is simplified. The scheme of the embodiment of the application can expand the interference problem of the subsequent newly-added wireless unit very conveniently and flexibly. Only newly added equipment is connected to the same clock synchronization signal, and the time slot occupation situation is matched, so that the system design does not need to be changed in a large scale, and the compatibility is better.

Example two

As shown in fig. 5, an embodiment of the present application further provides a method for solving coexistence interference, and the internal configurations of the first terminal device and the second terminal device in the method are shown in the electronic device 100, and will not be described here. The method specifically comprises the following steps:

s501: the network equipment respectively sends clock synchronization signals to the first terminal equipment and the second terminal equipment. Accordingly, the first terminal device and the second terminal device receive the clock synchronization signal.

S502: the first terminal equipment determines a first time unit occupied by the first terminal equipment in communication according to the clock synchronization signal.

For example, the first terminal device may determine at least one time unit according to the clock synchronization signal, and the first terminal device determines the first time unit in the at least one time unit.

S503: and the second terminal equipment determines a second time unit occupied by the communication of the second terminal equipment according to the clock synchronization signal.

For example, the second terminal device may determine the at least one time unit according to the clock synchronization signal, and the second terminal device may determine the second time unit according to the at least one time unit.

S504: and the second terminal equipment sends a first instruction to the first terminal equipment, wherein the first instruction is used for indicating a second time unit occupied by the communication of the second terminal equipment. Accordingly, the first terminal device receives the first indication.

S505: when the first time unit and the second time unit overlap, the first terminal device redistributes the time unit which can be occupied for the first terminal device and/or the second terminal device.

For example, the first time unit includes P slots, the second time unit includes Q slots, P and Q are both integers greater than 0, and the overlap between the first time unit and the second time unit may specifically be that at least one of the P slots overlaps with at least one of the Q slots, and the overlap may be complete overlap or partial overlap.

In this embodiment, when the service priority of the first terminal device is higher than the service priority of the second terminal device, the first terminal device may reallocate an occupiable third time unit for the second terminal device, where the third time unit is not overlapped with the first time unit. For example, the first terminal device may reallocate the third time unit to the second terminal device in the following manner: the first terminal equipment determines a time unit of which the first time unit and the second time unit are overlapped; the first terminal equipment removes the overlapped time units from a second time unit occupied by the original communication of the second terminal equipment to generate a third time unit; or, the first terminal device may determine a first time unit occupied by the first terminal device for communication, and reallocate a third time unit for the second terminal device based on the first time unit, where a criterion for allocating the third time unit is: the allocated third time unit does not overlap with the first time unit.

Or, when the service priority of the second terminal device is higher than the service priority of the first terminal device, the first terminal device allocates an occupiable fourth time unit to the first terminal device again, and the fourth time unit is completely not overlapped with the second time unit. For example, the first terminal device may reallocate the fourth time unit to the first terminal device in the following manner: the first terminal equipment determines a time unit of which the first time unit and the second time unit are overlapped; the first terminal equipment removes the overlapped time units from the first time units originally occupied by the first terminal equipment to generate a fourth time unit; or, the first terminal device determines a second time unit occupied by the second terminal device for communication, and allocates a fourth time unit to the first terminal device again by taking the second time unit as a reference, where a criterion for allocating the fourth time unit is as follows: the fourth time unit and the second time unit are not overlapped.

Or the first terminal device reallocates an occupiable fifth time unit for the first terminal device and reallocates an occupiable sixth time unit for the second terminal device, wherein the fifth time unit and the sixth time unit are not overlapped.

Accordingly, in this embodiment of the present application, after the first terminal device reallocates the time unit that can be occupied for the second terminal device, the first terminal device needs to notify the second terminal device of the reallocated time unit, and accordingly, the second terminal device performs communication based on the reallocated time unit. For example, if the first terminal device reallocates the third time unit or the sixth time unit to the second terminal device, the first terminal device needs to notify the second terminal device of the third time unit or the sixth time unit. Accordingly, the second terminal device communicates based on the third time unit or the sixth time unit.

Based on the method provided in fig. 5, the present application provides a specific example, as shown in fig. 6, which includes a satellite device, a device 1, and a device 2. The satellite device may correspond to the network device in fig. 5, the device 1 may correspond to the terminal device 1 in fig. 5, and the device 2 may correspond to the terminal device 2 in fig. 5. The method comprises the following steps:

the satellite device transmits a clock synchronization signal, which may be embodied as a Pulse Per Second (PPS), to the device 1 and the device 2, respectively. The device 1 determines the wireless signal occupancy based on the clock synchronization signal. For example, referring to fig. 5, the time slots occupied by the wireless signal of the device 1 include time slot 1 to time slot 5. The device 2 determines the wireless signal occupancy based on the clock synchronization signal. For example, referring to fig. 5, the time slots occupied by the wireless signal of the device 2 include time slot 0, time slot 1, time slot 2, time slot 6, time slot 7, time slot 8, and time slot 9. The device 1 and the device 2 can select to avoid the wireless transmission of the device or require an opposite terminal to avoid the wireless transmission based on the priority of the service level.

The service priority of the device 1 is set to be higher than that of the device 2, the device 2 can inform the device 1 of the time slot occupation condition of the device 2, and correspondingly, the device 1 can reallocate the time slot based on the time slot occupation conditions of the device 1 and the device 2. Or, the service priority of the device 2 is higher than that of the device 1, the device 1 may notify the device 2 of the slot occupation of the device 1, and the device 2 may reallocate the slots based on the slot occupation of the device 1 and the slot occupation of the device 2.

The scheme of this application, in being particularly useful for narrow and small space in the car, have the unordered communication between a plurality of independent mobile units, optimize the wireless performance of coexistence scene.
