Description

Technical Field

[0001] The present invention relates to the field of communications, and in particular to a method and terminal equipment for monitoring a physical downlink control channel (PDCCH), and a computer-readable storage medium. Background Art

[0002] In the existing Physical Downlink Control Channel (PDCCH) configuration, the PDCCH search space is semi-statically configured by the Radio Resource Control (RRC). Due to the diversity and constant changes in terminal device services, this semi-static PDCCH search space configuration may not always be able to match the changing service characteristics and scheduling intervals well. For example, the PDCCH search space configured by the network device for the terminal device corresponds to a smaller PDCCH monitoring period. The terminal device currently initiates a service with a larger packet transmission interval. Since the terminal device needs to consume power when monitoring the PDCCH, from the perspective of terminal device power saving, without affecting the service transmission delay, the terminal device prefers to use a PDCCH search space with a larger corresponding PDCCH monitoring period. However, the configuration of the PDCCH monitoring period cannot be adjusted dynamically, which is obviously not conducive to power saving of the terminal device. Summary of the invention

[0026] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] In order to provide a higher data transmission rate and improve user experience, the 5G next-generation mobile communication system (Newradio, NR) further increases the system bandwidth based on 4G. In 5G NR, for frequency bands below 6GHz, the maximum bandwidth supported by a single carrier is 100MHz; for frequency bands above 6GHz, the maximum bandwidth supported by a single carrier is 400MHz.

[0028] For a large carrier bandwidth, such as 100MHz, the bandwidth required by the terminal device is often very limited. If the terminal device is always required to detect and measure over the entire bandwidth, it will pose a great challenge to the power consumption of the terminal device and will not be conducive to power saving of the terminal device. Therefore, the concept of working bandwidth (Bandwidth Part, BWP) is introduced in 5G NR, that is, a part of continuous bandwidth is divided in the entire large bandwidth carrier for terminal devices to send and receive data. The terminal device only needs to perform related operations within this part of the bandwidth configured by the network device, thereby achieving the effect of energy saving of the terminal device.

[0029] Based on the 5G NR Rel-15 standard, for each service cell of the terminal device, the network device Radio Resource Control (RRC) can configure one or more BWPs for the terminal device on this service cell, and the maximum number of configurable BWPs is 4. At each moment, the terminal device can only have 1 activated downlink (DL) BWP and 1 activated uplink (UL) BWP on this service cell, and the terminal device can only send and receive data on the activated BWP. The following 4 methods can be used to implement BWP switching:

[0030] (1) BWP switching based on Physical Downlink Control Channel (PDCCH);

[0031] (2) BWP switching based on RRC (re)configuration;

[0032] (3) BWP switching based on timer timeout;

[0033] (4) BWP switching caused by random access initialization.

[0034] The terminal device receives the PDCCH sent by the network device to obtain the downlink or uplink scheduling information, thereby further completing the reception and transmission of service data. The time when the network device schedules the terminal device is not fixed. Since there is no relevant signaling to inform the terminal device whether the network device has sent the PDCCH to the terminal device, the terminal device needs to blindly detect the PDCCH. In order to reduce the complexity of the terminal device's blind detection, it is necessary to limit the set of blindly detected PDCCHs. Therefore, the concept of search space is introduced, that is, the set of PDCCH resources that the terminal device needs to blindly detect.

[0035] 5G NR PDCCH configuration: User Equipment (UE) monitors PDCCH on the PDCCH search space configured by the network device. The network device can configure up to 10 PDCCH search spaces for each DL BWP of the UE. Each PDCCH search space corresponds to a PDCCH monitoring period, and each search space is indexed by a search space (Search Space) identifier (Identity, Id). Each PDCCH search space is associated with a control resource set (Control Resource Set), each Control Resource Set corresponds to a frequency domain location, and each Control Resource Set is indexed by a Control Resource Set Id. The network device can configure up to 3 ControlResource Sets for each DL BWP of the UE.

[0036] However, in the existing Physical Downlink Control Channel (PDCCH) configuration, the PDCCH search space is semi-statically configured by the Radio Resource Control (RRC). Due to the diversity and constant changes in terminal device services, this semi-static PDCCH search space configuration may not always be able to match the changing service characteristics and scheduling intervals well. For example, the PDCCH search space configured by the network device for the terminal device corresponds to a smaller PDCCH monitoring period. The terminal device currently initiates a service with a larger packet sending interval. Since the terminal device needs to consume power when monitoring the PDCCH, from the perspective of terminal device power saving, without affecting the service transmission delay, the terminal device would rather use a PDCCH search space with a larger corresponding PDCCH monitoring period. However, the configuration of the PDCCH monitoring period cannot be adjusted dynamically, which is obviously not conducive to power saving of the terminal device.

[0052] The technical solution of the present invention is further described below by way of embodiments:

[0053] 1. A solution in which a network device sends an activation instruction and / or a deactivation instruction to a terminal device. Figure 2 As shown, it is a schematic diagram of an embodiment of a method for monitoring a physical downlink control channel PDCCH in an embodiment of the present invention, which may include:

[0054] 201. The network device sends configuration information to the terminal device.

[0055] The terminal device receives the configuration information sent by the network device. It can be understood that the configuration information can be RRC configuration information. The configuration information is used by the terminal device to configure at least one PDCCH search space, or at least one PDCCH search space group, or at least one control resource set, or at least one control resource set group for each downlink bandwidth.

[0056] Optionally, the configuration information is used for the terminal device to configure at least one downlink bandwidth (DL BWP).

[0059] Optionally, the initial state of at least one PDCCH search space, the initial state of at least one PDCCH search space group, the initial state of at least one control resource set, or the initial state of at least one control resource set group may be an activated state, or a deactivated state, or may be indicated as an activated / deactivated state in the indication information sent by the network device.

[0060] 203.

[0061] The indication information includes an activation instruction and / or a deactivation instruction; the status information includes information in an activated state and / or information in a deactivated state.

[0062] It can be understood that the network device activates and / or deactivates part of the PDCCH search space according to the service requirements and power saving requirements of the terminal device, and sends activation instructions and / or deactivation instructions to the terminal device. Among them, the service requirements can be understood as the quality of service (Quality of Service, QOS), and the power saving requirements are reported by the terminal device to the network device through auxiliary information.

[0063] Optionally, the indication information is used to indicate status information of at least one PDCCH search space, status information of at least one PDCCH search space group, status information of at least one control resource set, or status information of at least one control resource set group.

[0064] Optionally, status information of at least one PDCCH search space group, status information of at least one control resource set, or status information of at least one control resource set group is used to determine status information of at least one PDCCH search space.

[0065] Optionally, (1) when at least one PDCCH search space is configured,

[0066] An activation instruction is used for the terminal device to activate a corresponding first PDCCH search space in at least one PDCCH search space, determine that the first PDCCH search space is in an activated state; monitor the PDCCH in the first PDCCH search space in the activated state; and / or,

[0067] The deactivation instruction is used for the terminal device to deactivate the corresponding second PDCCH search space in at least one PDCCH search space, determine that the second PDCCH search space is in a deactivated state; and stop monitoring PDCCH in the second PDCCH search space in the deactivated state.

[0077] Optionally, the indication information is indicated by a bitmap.

[0078] Exemplarily, the indication information, i.e., the activation instruction, and / or the deactivation instruction, can be indicated using a bitmap. For example, a bitmap with a length of 10 bits, the i-th bit represents the state of the i-th SearchSpaceId (SearchSpaceId-i). The value of this bit is 1, which means that SearchSpaceId-i is in the activated state, and 0, which means that SearchSpaceId-i is in the deactivated state. Alternatively, 1 represents the deactivated state, and 0 represents the activated state.

[0079] It can be understood that, through the bitmap, the network device can simultaneously activate or deactivate multiple PDCCH search spaces, multiple PDCCH search space groups, multiple control resource sets, or multiple control resource set groups.

[0080] Optionally, the indication information is carried in a medium access control control unit MAC CE or downlink control information DCI.

[0081] Exemplarily, the indication information may include but is not limited to being implemented through the following signaling:

[0082] (1) Define a new medium access control (MAC) control element (CE). Here, the PDCCH search space is used as an example to illustrate, such as the activation / deactivation MAC CE of the PDCCH search space. For this purpose, a new logical channel (LC) ID needs to be introduced to identify the MAC CE. The MAC CE may also require a serving cell ID and / or a BWP ID to indicate which BWP of which specific cell.

[0083] It can be understood that, for the indication information of the PDCCH search space group, the control resource set, or the control resource set group, reference can be made to the description of the indication information of the above-mentioned PDCCH space, which will not be repeated here.

[0084] (2) The existing DCI format may be extended, or a new DCI format may be introduced, to represent the indication information.

[0089] It should be noted that, in the embodiment of the present invention, steps 201-204 are optional steps.

[0103] And / or, the terminal device determines the status information of at least one PDCCH search space, which may include: the terminal device deactivates the corresponding second control resource set in at least one control resource set according to the deactivation instruction, and determines that all PDCCH search spaces associated with the second control resource set in the deactivated state are in the deactivated state; the terminal device performs PDCCH monitoring processing on at least one PDCCH search space according to the status information of at least one PDCCH search space, which may include: the terminal device stops monitoring PDCCH on all PDCCH search spaces associated with the second control resource set in the deactivated state.

[0104] 4) When at least one control resource set group is configured,

[0105] The terminal device determines the status information of at least one PDCCH search space, which may include: the terminal device activates the corresponding first control resource set group in the at least one control resource set group according to the activation instruction, and determines that all PDCCH search spaces associated with each control resource set in the first control resource set group that is in an activated state are in an activated state; the terminal device performs PDCCH monitoring processing on the at least one PDCCH search space according to the status information of the at least one PDCCH search space, which may include: the terminal device monitors the PDCCH on all PDCCH search spaces associated with each control resource set in the first control resource set group that is in an activated state.

[0106] And / or, the terminal device determines the status information of at least one PDCCH search space, which may include: the terminal device deactivates the corresponding second control resource set group in the at least one control resource set group according to the deactivation instruction, and determines that all PDCCH search spaces associated with each control resource set in the second control resource set group in the deactivated state are in the deactivated state; the terminal device performs PDCCH monitoring processing on at least one PDCCH search space according to the status information of the at least one PDCCH search space, which may include: the terminal device stops monitoring PDCCH on all PDCCH search spaces associated with each control resource set in the second control resource set group in the deactivated state.

[0107] For example, Figure 3 FIG. 1 is a schematic diagram of activating or deactivating a PDCCH search space in an embodiment of the present invention. The terminal device stops monitoring the PDCCH on the deactivated PDCCH search space and starts monitoring the PDCCH on the activated PDCCH search space according to the received PDCCH search space activation / deactivation instruction.

[0108] In an embodiment of the present invention, an activation / deactivation mechanism is introduced for at least one PDCCH search space, at least one PDCCH search space group, at least one control resource set, or at least one control resource set group statically configured by RRC, and the network device can activate / deactivate one or more PDCCH search spaces, PDCCH search space groups, control resource sets, or control resource set groups. The terminal device monitors PDCCH at the time-frequency resource positions corresponding to these activated PDCCH search spaces, PDCCH search space groups, control resource sets, or control resource set groups. Among them, different services have different requirements for PDCCH search space. For example, for Ultra-reliable and Low Latency Communications (URLLC) services, a denser PDCCH search space can be used; on the contrary, for Enhanced Mobile Broadband (eMBB) services or delay-insensitive Internet of Things (IoT) services, a sparser PDCCH search space can be used. Moreover, the introduction of the PDCCH search space activation / deactivation mechanism facilitates network equipment to more flexibly control PDCCH monitoring of terminal equipment, thereby achieving a reasonable balance between service scheduling and power saving of terminal equipment.

[0109] Second, all automatic deactivation solutions are implemented. Figure 4 As shown, it is a schematic diagram of another embodiment of a method for monitoring a physical downlink control channel PDCCH in an embodiment of the present invention, which may include:

[0110] 401. The network device sends configuration information to the terminal device.

[0111] 402. The terminal device configures at least one PDCCH search space, at least one PDCCH search space group, at least one control resource set, or at least one control resource set group for each downlink bandwidth according to the configuration information.

[0112] It should be noted that steps 401 and 402 can refer to Figure 2 Steps 201 and 202 in the illustrated embodiment will not be described in detail here.

[0113] 403. The terminal device configures a deactivation timer according to the configuration information.

[0114] The terminal device configures the deactivation timer according to the configuration information, which can be explained in different situations, as shown below:

[0147] The terminal device performs PDCCH monitoring processing on at least one PDCCH search space according to the state information of at least one PDCCH search space, including:

[0148] The terminal device monitors the PDCCH on all PDCCH search spaces associated with the third control resource set in an activated state; or, the terminal device stops monitoring the PDCCH on all PDCCH search spaces associated with the third control resource set in a deactivated state.

[0149] (4) at least one control resource set group includes a third control resource set group;

[0150] The terminal device determines the state information of at least one PDCCH search space, which may include:

[0151] If the terminal device receives a PDCCH sent by the network device on any PDCCH search space associated with any control resource set in the third control resource set group, the terminal device starts or restarts a fourth deactivation timer corresponding to the third control resource set group;

[0152] If the fourth deactivation timer times out, and the terminal device determines that the third control resource set group is the only control resource set group in an activated state, the terminal device does not perform an automatic deactivation operation, and determines that all PDCCH search spaces associated with each control resource set in the third control resource set group in an activated state are in an activated state; or, if the fourth deactivation timer times out, and the terminal device determines that the third control resource set group is not the only control resource set group in an activated state, the terminal device performs an automatic deactivation operation, and determines that all PDCCH search spaces associated with each control resource set in the third control resource set group in a deactivated state are in a deactivated state;

[0153] The terminal device performs PDCCH monitoring processing on at least one PDCCH search space according to the state information of at least one PDCCH search space, which may include:

[0154] The terminal device monitors PDCCH on all PDCCH search spaces associated with each control resource set in the third control resource set group that is in an activated state; or, the terminal device stops monitoring PDCCH on all PDCCH search spaces associated with each control resource set in the third control resource set group that is in a deactivated state.

[0155] For example, Figure 5 FIG. 1 is a schematic diagram of automatically deactivating a PDCCH search space in an embodiment of the present invention. Taking the PDCCH search space as an example, the terminal device executes the deactivationTimer mechanism in all PDCCH search spaces, which may include:

[0156] When a terminal device receives a PDCCH sent by a network device on a certain PDCCH search space, the terminal device starts or restarts the deactivation Timer corresponding to the search space; when the deactivation Timer corresponding to a certain PDCCH search space times out, the terminal device determines whether the search space is the only search space in an activated state; if so, the terminal device does not perform an automatic deactivation operation and continues to monitor the PDCCH on the PDCCH search space; if not, the terminal device automatically deactivates the PDCCH search space and stops monitoring the PDCCH on the PDCCH search space.

[0157] It should be noted that, in the embodiment of the present invention, for at least one PDCCH search space, at least one PDCCH search space group, at least one control resource set, or at least one control resource set group that performs automatic deactivation, after automatic deactivation, it is also possible to use Figure 2 The mechanism of the activation instruction and / or the deactivation instruction in the illustrated embodiment may be specifically referred to Figure 2 The embodiments shown will not be described in detail here.

[0158] In an embodiment of the present invention, an automatic deactivation mechanism is introduced for at least one PDCCH search space, at least one PDCCH search space group, at least one control resource set, or at least one control resource set group statically configured by RRC, and each PDCCH search space, each PDCCH search space group, each control resource set, or each control resource set group runs its own deactivation Timer. When the deactivation Timer corresponding to a PDCCH search space, a PDCCH search space group, a control resource set, or a control resource set group times out, the terminal device determines whether the PDCCH search space is the only PDCCH search space in an activated state. If it is the only PDCCH search space in an activated state, automatic deactivation is not performed; or, the terminal device determines whether the PDCCH search space group is the only PDCCH search space group in an activated state. If it is the only PDCCH search space group in an activated state, automatic deactivation is not performed; or, the terminal device determines whether the control resource set is the only control resource set in an activated state. If it is the only control resource set in an activated state, automatic deactivation is not performed; or, the terminal device determines whether the control resource set group is the only control resource set group in an activated state. If it is the only control resource set group in an activated state, automatic deactivation is not performed.

[0159] Among them, different services have different requirements for PDCCH search space. For example, for Ultra-reliable and Low Latency Communications (URLLC) services, a denser PDCCH search space can be used; on the contrary, for Enhanced Mobile Broadband (eMBB) services or latency-insensitive Internet of Things (IoT) services, a sparser PDCCH search space can be used. Moreover, the introduction of an automatic deactivation mechanism can save the activation / deactivation signaling overhead of network devices and achieve a reasonable balance between service scheduling and terminal device power saving.

[0160] 3. Some solutions do not implement automatic deactivation. Figure 6 As shown, it is a schematic diagram of another embodiment of a method for monitoring a physical downlink control channel PDCCH in an embodiment of the present invention, which may include:

[0161] 601. The network device sends configuration information to the terminal device.

[0162] 602. The terminal device configures at least one PDCCH search space, at least one PDCCH search space group, at least one control resource set, or at least one control resource set group for each downlink bandwidth according to the configuration information.

[0164] 603. The terminal device configures a deactivation timer according to the configuration information.

[0165] The terminal device configures the deactivation timer according to the configuration information, which can be explained in different situations, as shown below:

[0166] (1) When the configuration information includes the fifth duration of the fifth deactivation timer and the specific information of the third target PDCCH search space, the terminal device configures the fifth deactivation timer; wherein the specific information of the third target PDCCH search space is used to indicate that the fifth deactivation timer is not applied to the third target PDCCH search space, and the fifth deactivation timer corresponds to other PDCCH search spaces in at least one PDCCH search space except the third target PDCCH search space.

[0167] (2) When the configuration information includes the sixth duration of the sixth deactivation timer and the specific information of the target PDCCH search space group, the terminal device configures the sixth deactivation timer;

[0170] (4) When the configuration information includes the eighth duration of the eighth deactivation timer and the specific information of the target control resource set group, the terminal device configures the eighth deactivation timer; wherein the specific information of the target control resource set group is used to indicate that the eighth deactivation timer does not apply to the target control resource set group, and the eighth deactivation timer corresponds to other control resource set groups in at least one control resource set group except the target control resource set group.

[0172] It can be understood that the configured deactivation timer (deactivation Timer) is the longest PDCCH monitoring time allowed for a terminal device not to receive a PDCCH in the PDCCH search space, and is applicable to other PDCCH search spaces in at least one PDCCH search space except the target PDCCH search space, other PDCCH search space groups in at least one PDCCH search space group except the target PDCCH search space group, other control resource sets in at least one control resource set except the target control resource set, or other control resource set groups in at least one control resource set group except the target control resource set group.

[0173] 604. The terminal device determines status information of at least one PDCCH search space according to the configuration information.

[0174] It should be noted that step 604 in the embodiment of the present invention can refer to Figure 4Step 404 in the illustrated embodiment will not be described in detail here. Optionally, the timing of steps 403 and 404 is not limited.

[0175] 605. The terminal device performs PDCCH monitoring processing on at least one PDCCH search space according to status information of at least one PDCCH search space, where the status information includes information in an activated state and / or information in a deactivated state.

[0176] It should be noted that, in an embodiment of the present invention, the terminal device determines the status information of at least one PDCCH search space according to the configuration information, and performs PDCCH monitoring processing on at least one PDCCH search space according to the status information of the at least one PDCCH search space. For other PDCCH search spaces in at least one PDCCH search space except the third target PDCCH search space, other PDCCH search space groups in at least one PDCCH search space group except the target PDCCH search space group, other control resource sets in at least one control resource set except the target control resource set, or other control resource set groups in at least one control resource set group except the target control resource set, reference can be made to the following. Figure 4 The description in the illustrated embodiment will not be repeated here.

[0177] Optionally, the PDCCH search space, PDCCH search space group, control resource set, and control resource set group used in the automatic deactivation mechanism in the embodiment of the present invention may also use Figure 2 The mechanism of activating the instruction in the embodiment shown is to activate it. For details, please refer to Figure 2 The description in the illustrated embodiment will not be repeated here.

[0178] Optionally, although the automatic deactivation mechanism is not applied, it can also be applied to the third target PDCCH search space in at least one PDCCH search space, the target PDCCH search space group in at least one PDCCH search space group, the target control resource set in at least one control resource set, and the target control resource set group in at least one control resource set group. Figure 2 The mechanism of deactivating the instruction in the embodiment shown is to deactivate it. For details, please refer to Figure 2 The description in the illustrated embodiment will not be repeated here.

[0179] Optionally, the terminal device performs PDCCH monitoring processing on at least one PDCCH search space according to state information of at least one PDCCH search space, which may include:

[0180] (1) The terminal device monitors the PDCCH in the third target PDCCH search space in an activated state, or stops monitoring the PDCCH in the third target PDCCH search space in a deactivated state, according to the indication information of the third target PDCCH search space;

[0181] (2) The terminal device monitors the PDCCH on all PDCCH search spaces in the target PDCCH search space group in an activated state according to the indication information of the target PDCCH search space group, or stops monitoring the PDCCH on all PDCCH search spaces in the target PDCCH search space group in a deactivated state;

[0182] (3) The terminal device monitors the PDCCH on all PDCCH search spaces associated with the target control resource set in an activated state, or stops monitoring the PDCCH on all PDCCH search spaces associated with the target control resource set in a deactivated state, according to the indication information of the target control resource set;

[0184] For example, Figure 7 As shown, it is a schematic diagram of partially automatically deactivating the PDCCH search space in an embodiment of the present invention. Taking the PDCCH search space as an example for explanation, it is assumed that the network device configures PDCCH search space 1 as a PDCCH search space that cannot be deactivated. The terminal device executes the deactivation Timer mechanism in other PDCCH search spaces other than the target PDCCH search space, which may include: when the terminal device receives a PDCCH sent by the network on a certain PDCCH search space, the terminal device starts or restarts the deactivation Timer corresponding to the PDCCH search space; when the deactivation Timer corresponding to a certain PDCCH search space times out, the terminal device automatically deactivates the PDCCH search space and stops listening to the PDCCH on the PDCCH search space.

[0185] The target PDCCH search space cannot be automatically deactivated, so in the worst case, when no PDCCH is sent in all PDCCH search spaces, there is still a target PDCCH search space in an activated state for use by the network device to schedule the PDCCH.

[0186] In an embodiment of the present invention, an automatic deactivation mechanism can be introduced for at least one PDCCH search space, at least one PDCCH search space group, at least one control resource set, or at least one control resource set group statically configured by RRC, and each PDCCH search space, each PDCCH search space group, each control resource set, or each control resource set group runs its own deactivation timer; wherein the network device specifies that the target PDCCH search space does not run the deactivation timer, specifies that the target PDCCH search space group does not run the deactivation timer, specifies that the target control resource set does not run the deactivation timer, or specifies that the target control resource set group does not run the deactivation timer, that is, it cannot be automatically deactivated. Among them, different services have different requirements for PDCCH search space. For example, for Ultra-reliable and Low Latency Communications (URLLC) services, a denser PDCCH search space can be used; on the contrary, for Enhanced Mobile Broadband (eMBB) services or latency-insensitive Internet of Things (IoT) services, a sparser PDCCH search space can be used. In addition, the introduction of an automatic deactivation mechanism can save the activation / deactivation signaling overhead of network devices, achieving a reasonable balance between service scheduling and terminal device power saving.

[0197] Combine the following Fig.10 A detailed introduction to the various components of the mobile phone:

[0198] The RF circuit 1010 can be used for receiving and sending signals during information transmission or calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 1080 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 1010 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 1010 can also communicate with the network and other devices through wireless communication.

[0199] The memory 1020 can be used to store software programs and modules. The processor 1080 executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory 1020. The memory 1020 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 1020 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

Optionally, the touch panel 1031 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 1080, and can receive and execute commands sent by the processor 1080.
