Description

The present application relates to the field of communication technologies, and in particular, to an information detection method, a communication device, and a computer-readable storage medium.

Background technique

And mediate downstream data. Therefore, in order to receive DCI, the terminal needs to perform blind detection (BD) on multiple physical downlink control channel (Physical Downlink Control Channel, PDCCH) candidate positions to determine whether there is a DCI sent to itself. Each PDCCH is composed of one or more control channel elements (CCEs).

In the prior art, only the number of PDCCH candidate positions that the terminal needs to perform blind detection and the number of non-overlapping CCEs are specified, that is, the terminal continues to perform blind detection at multiple PDCCH candidate positions until the PDCCH that needs to be detected is reached The number of candidate positions, or until the number of non-overlapping CCEs to be detected.

Therefore, when performing the blind detection in the existing DCI signal detection method, the blind detection can be terminated only when the number of PDCCH candidate positions or the number of non-overlapping CCEs is reached; otherwise, the blind detection process cannot be stopped, which will cause the terminal Continuously performing the blind inspection process consumes a large amount of power.

detailed description

The terms used in the embodiments of the present application are only used to explain specific examples of the present application, and are not intended to limit the present application.

In the following, some terms in this application are explained so as to facilitate understanding by those skilled in the art.

1) The terminal, also known as user equipment (UE), is a device that provides voice and / or data connectivity to users, such as handheld devices with wireless connectivity, vehicle-mounted devices, and so on. Common terminals include, for example, mobile phones, tablet computers, notebook computers, handheld computers, mobile Internet devices (MID), and wearable devices, such as smart watches, smart bracelets, pedometers, and the like.

2) Network equipment, also known as a base station or radio access network (RAN) device, is a device that connects terminals to a wireless network, including but not limited to: evolved Node B (evolved Node B) ENB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (BTS) For example, Home NodeB, or Home NodeB (HNB), Baseband Unit (BaseBand Unit, BBU). In addition, it may also include a Wifi access point (Access Point, AP) and the like.

3) "At least one" means one or more than one; "multiple" means two or more. "And / or" describes the association relationship of related objects, and indicates that there can be three kinds of relationships. For example, A and / or B can mean: there are three cases of A alone, A and B, and B alone. The character "/" generally indicates that the related objects are an "or" relationship.

A specific application scenario of this application may refer to FIG. 1, which is an interaction scenario between a terminal and a network device: the network device communicates with the terminal, and the terminal receives downlink control information sent by the network device, and accepts downlink data sent by the network device or to the network. The device sends uplink data. In this scenario, the terminal performs a blind detection of DCI at multiple PDCCH candidate positions.

Specifically, for a downlink data transmission process between the network device and the terminal, refer to FIG. 2. The network device and the terminal transmit DCI through the PDCCH, transmit downlink data through the physical downlink shared channel (PDSCH), and transmit uplink data through the physical uplink shared channel (PUSCH). DCI carries downlink data scheduling information. Network equipment sends downlink data to the terminal according to the scheduling information in the DCI. After receiving the DCI, the terminal also receives and demodulates the time-frequency resource location and configuration parameters indicated by the DCI. Downlink data; and the terminal may also send uplink data to the network device at the time-frequency resource location and configuration parameter indicated by the DCI.

The scheduling information carried in the DCI may be used to indicate, but not limited to, the following information: telling the terminal what time-frequency resource location is, and / or what configuration parameters are used to receive and demodulate downlink data. For example, the DCI can instruct the terminal at what time-frequency resource location, which modulation and coding strategy (Modulation and Coding Scheme, MCS), and what redundancy version (Redundancy Version, RV) to continue to receive and demodulate downlink data.

In this interaction scenario, the terminal needs to receive the DCI sent by the network device to itself, and it needs to perform blind detection on the candidate position of the PDCCH. That is, the terminal monitors multiple candidate positions of the PDCCH (Candidate). In all DCIs, check whether there is a DCI sent to itself.

In addition, each PDCCH is composed of one or more CCEs, and the number of CCEs contained in one PDCCH is called an aggregation level (AL). In the prior art, there are 5 types of AL, which are: 1, 2, 4, 8, and 16. For example, if a PDCCH is composed of 1 CCE, the AL of the PDCCH is 1; if a PDCCH is composed of 4 CCEs, the AL of the PDCCH is 4.

When the terminal performs a blind DCI test, it will receive multiple DCIs sent to itself. These DCIs may include DCI for scheduling uplink and downlink unicast data, and may also include DCI for other scheduling purposes; and these DCIs may include DCI for non-slot scheduling, and That is, DCI used for scheduling data in this time slot; or, these DCIs may also include DCI used for scheduling across time slots, that is, DCI used for scheduling data in other time slots. At this time, you can refer to Figure 3. Each square in Figure 3 represents a time slot in a cell. In the first time slot, the terminal receives a total of 4 DCIs by monitoring the PDCCH, including 2 One DCI for scheduling downlink data in this time slot, one DCI for scheduling downlink data in the second time slot, and one DCI for scheduling uplink data in the third time slot.

In the existing 5G NR technology, the terminal is subject to the following two constraints when blindly detecting DCI:

1) The number of PDCCH Candidates to be monitored;

2) The number of non-overlapping CCEs to be detected.

Therefore, if the terminal is not configured with carrier aggregation (CA), or if the terminal is configured with CA but the number of configured cells does not exceed 4, the terminal needs to be monitored in each time slot and in each cell. Refer to Table 1 for the maximum number of PDCCH Candidates, and refer to Table 2 for the maximum number of non-overlapping CCEs that the terminal needs to detect.

Table 1

Table 2

Subcarrier interval	Maximum number of non-overlapping CCEs to be detected in each time slot and each cell
15kHz	56
30kHz	56
60kHz	48
120kHz	32

Then, based on the 5G NR technology, only two constraints, the number of PDCCHs that need to be monitored and the number of non-overlapping CCEs that need to be detected, are specified. Then, the terminal can only reach the number of PDCCH candidate positions when performing blind detection. Or the blind test will be terminated only when the number of non-overlapping CCEs is reached; otherwise, the blind test process cannot be stopped.

It can be known from Tables 1 and 2 that under the current blind detection termination conditions, the terminal still needs to detect a large number of DCIs before it can stop the blind detection, and the terminal consumes large power during the blind detection process. Therefore, how to further reduce the power consumption of the terminal during the blind detection process has become an urgent technical problem to be solved.

The technical solution provided in this application aims to solve the above technical problems of the prior art, and proposes the following solutions: The network device configures the terminal to detect the maximum number of DCIs within a certain time-frequency resource range, so as to terminate the blindness through the maximum number. Inspection process, thereby reducing the number of blind inspections and reducing the power consumption of the terminal.

The following specifically describes the technical solution of the present application and how the technical solution of the present application solves the foregoing technical problems in specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

Example one

An embodiment of the present application provides an information detection method. Please refer to the schematic diagram of the interaction process shown in FIG. 4. The method includes the following steps:

S102. The network device determines at least one maximum detection number.

Each maximum detection number is used by the terminal to determine the maximum number of downlink control information DCIs that the terminal can detect when it performs a blind detection of a physical downlink control channel PDCCH within a specified time-frequency resource range.

S104. The network device sends at least one maximum detection number to the terminal.

This is to enable the terminal to stop blind PDCCH detection according to at least one maximum detection number.

S106. The terminal receives at least one maximum detection number sent by the network device.

S108. The terminal performs blind PDCCH detection within a specified time-frequency resource range.

S110. The terminal stops the PDCCH blind detection according to at least one maximum detection number.

The essence of S102 is that the network device configures at least one maximum detection number for the terminal.

The network device configures one or more maximum detection numbers for all DCIs in the terminal, and each maximum detection number is used to determine the maximum of all DCIs that the terminal can detect when the terminal performs blind PDCCH detection within a specified time-frequency resource range. number.

Alternatively, the network device may also configure at least one maximum detection number for the terminal based on the type of DCI.

Specifically, the DCI between the network device and the base station may have multiple different categories. The category division method of the DCI involved in this application may include, but is not limited to, at least one of the format category, the size category, and the use category. Perform DCI classification.

Specifically, the DCI classification method may include, but is not limited to, the following implementation methods:

In a specific implementation scenario, the DCI may be divided into at least two DCI formats according to different DCI formats. For example, according to the DCI format, the DCI is divided into the following types: format 0-0, format 0-1, format 1-0, format 1-1, format 2-0, format 2-1, format 2-2, and format 2-3.

Or, in another specific implementation scenario, category classification may also be performed according to the DCI size. In specific implementation, the size can be characterized according to the bit value of the DCI. For example, according to the size of the bit value of the DCI, DCI whose bit value is greater than a preset threshold is classified into one class, and DCI whose bit value is less than or equal to the preset threshold is classified into another class. It can be known that, when performing the division, there may be one or more preset thresholds. Therefore, the divided DCI categories include at least two categories, and details are not described again.

Or, in another specific implementation scenario, category classification may also be performed according to DCI usage. For example, based on whether DCI is used to schedule data in this time slot, the DCI used to schedule data in this time slot is classified into one type, and DCI used to schedule data in other time slots is classified into another type. For another example, the DCI used for scheduling downlink data may be classified into one type based on whether DCI is used for scheduling downlink data, and the DCI used for scheduling uplink data may be classified into another type. In addition, regarding the classification method according to the use of DCI, multiple use factors can also be considered in combination. Taking the foregoing two examples as an example, DCI can be divided into four categories by combining the two use factors of whether it is used to schedule data in this time slot and whether it is used to schedule downlink data. It can be known that according to the purpose classification of DCI, there can be many other divisions, which are no longer exhaustive.

In addition, in specific implementation, DCI classification may also be performed in combination with the combination of the at least two classification strategies. For example, there is a corresponding relationship between DCI format and usage. Therefore, DCI can be divided into two categories according to the usage corresponding to each DCI format: format 0-0, format 0-1, format 1-0, and format 1-1. These DCI formats are DCIs used for scheduling data; format 2-0, format 2-1, format 2-2, and format 2-3 are another type. These DCI formats are group common DCI.

Based on DCI may have N categories (N is an integer greater than or equal to 1), the maximum detection number is further used to determine the M categories that the terminal can detect when the terminal performs blind PDCCH detection within the specified time-frequency resource range. The maximum number of DCIs. At this time, M is an integer greater than or equal to 1, and M is less than or equal to N.

At this time, the manner in which the network device configures the terminal with at least one maximum detection number may include, but is not limited to, the following implementation manners:

First implementation manner: The network device configures N maximum detection numbers for the terminal, and N is the number of categories of DCI, that is, the N maximum detection numbers correspond to the N-type DCI one-to-one. At this time, each maximum detection number is used to determine the maximum number of types of DCI that the terminal can detect when the terminal performs blind PDCCH detection within a specified time-frequency resource range.

The second implementation method: the network device configures X maximum detection numbers for the terminal, X is a number greater than 1 and less than N, and N is the number of categories of DCI, that is, one maximum detection number corresponds to one or more categories of DCI . At this time, a maximum detection number can be used to determine the maximum number of DCIs that the terminal can detect when the terminal performs blind PDCCH detection within the specified time-frequency resource range; or it can be used to determine the terminal's range of specified time-frequency resources The maximum number of multiple types of DCI that can be detected by the terminal when the PDCCH blind detection is performed within. At this time, some DCI categories have the same maximum detection number. For example, DCI is divided into 3 types, and the network device is configured with 2 maximum detection numbers for the terminal. Among them, one maximum detection number is used to determine the maximum number of detections of one type of DCI, and the other maximum detection number is used to determine the other The maximum number of detections for two types of DCI. Both types of DCI have the same maximum number of detections.

In addition, considering that the implementation scenario where the network device interacts with the terminal may involve multiple terminals, when performing step S102, further consideration may be given to setting a maximum number of detections for different terminals or different types of terminals. The classification method of the terminal may be divided according to needs, and details are not described again. At this time, the method for determining the maximum number of detections is similar to the foregoing method for determining the maximum number of detections based on the category of DCI. You can set a unified maximum number of detections for all terminals, or set a DCI corresponding to each category for each type of terminal The maximum number of detections, or the same maximum number of detections can be set for some terminals among all terminals, which will not be described again. In this implementation scenario, the network device also needs to send to the terminal instruction information indicating which maximum detection number corresponds to which terminal.

An implementation manner of determining at least one maximum detection number according to a category of DCI and an implementation manner of determining at least one maximum detection number according to a category of a terminal may be used in combination, and details are not described again.

In the embodiment of the present application, when the network device determines at least one maximum detection number for the terminal, in addition to considering the terminal type and the type of DCI, the method for setting the maximum detection number is also involved. For example, the network device may determine at least one maximum detection number for all DCIs in a terminal.

At this time, in a specific implementation, the network device may determine a value determined by a value for the terminal as the maximum detection number. For example, the network device may determine a value A for the terminal as the maximum detection number.

Alternatively, the network device may determine a plurality of values determined for the terminal as the maximum detection number. For example, the network device may determine a value set including multiple specific values for the terminal, and determine each value in the value set as the maximum detection number. At this time, each determined maximum detection number is used to determine the terminal. When the physical downlink control channel PDCCH blind detection is performed within a specified time-frequency resource range, the maximum number of downlink control information DCIs that can be detected by the terminal.

In order to facilitate understanding, the embodiment of the present application also provides a form in which the at least one maximum detection number is characterized in a set manner:

In an implementation process, at least one maximum detection number can be characterized by an enumerated set, which can be expressed as: {n1, n2, ..., nx, noLimit}. The enumerated set is used to indicate that the maximum number of detections is One, two ... n, or an unlimited maximum number. Among them, the “noLimit” item can be set or deleted as needed. In specific implementation, it can be implemented by not configuring the parameter for the terminal. For example, its expression can be: {n1 , n2,…, nx}.

In another implementation process, the at least one maximum detection number may also be characterized by means of a set of numeric types. For example, at least one maximum detection number may be characterized by an integer set.

In addition, each maximum detection parameter configured by the network device for the terminal involves the concept of specifying a time-frequency resource range, and the time-frequency resource range involved in the embodiment of the present application includes two dimensions: a time domain dimension and a frequency domain dimension. The specified time-frequency resource ranges corresponding to each maximum detection number can be configured as required, and the specified time-frequency resource ranges corresponding to different maximum detection numbers can be the same or different.

In a specific implementation scenario, the specified time-frequency resource range may include but is not limited to the following:

All active downlink carriers (DL cells) in one or more time slots;

One or more downlink carriers in one or more time slots;

One or more Bandwidth Part (BWP) in one or more time slots;

One or more control resource sets (CORESET);

One or more search spaces Search Space.

In the configuration method of the specified time-frequency resource range, the time slot is a range limitation method in the time domain dimension, DL Cell, downlink carrier, and BWP are the range limitation method in the frequency domain dimension, and CORESET and Search Space both consider the time domain and The way to limit the two dimensions of the frequency domain.

Based on the at least one maximum detection number determined in S102, when the sending step in S104 is performed, all the maximum detection numbers determined in S102 may be sent to the terminal, or a part of all the maximum detection numbers determined in S102 may be the largest. The detection number is sent to the terminal. And, in some possible implementation scenarios, the network device may send the maximum number of detections to the terminal at one time, or may sequentially send multiple maximum number of detections to the terminal in sequence according to a certain frequency or period.

For example, if S102 determines that at least one maximum detection number is: {n1, n2, ..., nx}, when performing step S104, the network device may send the maximum detection number set {n1, n2, ..., nx} to the terminal Or, one or more of the maximum detection numbers, such as n1 and n5, may be sent to the terminal.

An implementation manner of implementing S104 is that the network device sends the at least one maximum detection number to the terminal by using the first control signaling.

The first control signaling involved in the embodiment of the present application may include, but is not limited to, at least one of Radio Resource Control (RRC) signaling, Media Access Control Element MAC CE signaling, and DCI signaling. Species.

In the embodiment of the present application, specifying the time-frequency resource range specifically indicates the time-frequency range of the terminal performing blind PDCCH detection, and is closely related to the maximum detection number.

Then, in an implementation scenario, the configuration information used to indicate the specified time-frequency resource range may be sent to the terminal through the first control signaling together with the maximum detection number. Alternatively, in another implementation scenario, the first control signaling may include only at least one maximum detection number, and the configuration information about the specified time-frequency resource range may be additionally sent to the terminal. For example, the network device sends a configuration information indicating the specified time-frequency resource range to the terminal separately before, after, or at the same time. Alternatively, the network device may also use the configuration information before, after, or at the same time as the execution of S104. The configuration information indicating the specified time-frequency resource range is sent to the terminal together after other information is packaged.

In specific implementation, the configuration information used to indicate the specified time-frequency resource range is configured and sent to the terminal in an information element.

Therefore, when the specified time-frequency resource range configured is all downlink carriers in one or more time slots, the information may be configured in an information element of Physical Cell Group Configuration. in.

Alternatively, when the specified time-frequency resource range configured is one or more downlink carriers in one or more time slots, the information may be configured in an information element of a serving cell configuration (Serving Cell Config).

Alternatively, when the specified time-frequency resource range configured is one or more BWPs in one or more time slots, the information may be configured in the information element BWP.

Alternatively, when the specified time-frequency resource range configured is one or more CORESETs, the information may be configured in an information element of a control resource set (Control Resource Set).

Alternatively, when the specified time-frequency resource range configured is one or more Search Spaces, the information may be configured in the information element Search Space.

Therefore, if at least one maximum detection number is carried in the first control signaling and sent to the terminal, the terminal needs to receive the first control signaling sent by the network device to obtain at least one maximum carried by the first control signaling. Detection number.

It should be noted that if the configuration information used to indicate the specified time-frequency resource range and the maximum number of detections are sent to the terminal through the first control signaling, the terminal may perform the blindness described in S108 after receiving the first control signaling.测 过程。 Inspection process. Conversely, if the configuration information used to indicate the specified time-frequency resource range is sent to the terminal separately from the maximum detection number, the terminal needs to receive these two information before starting the blind detection process described in S108.

In addition, during the PDCCH blind detection process, only one maximum detection parameter is valid at the same time. Therefore, for any terminal, the process of the terminal performing blind detection of PDCCH and stopping blind detection may include the following processing methods:

The first type: the maximum number of detections received by the terminal for all DCIs or types of DCI is one.

If the terminal receives only one maximum detection number for all DCIs of the terminal, the PDCCH blind detection is performed according to the specified time-frequency resource range corresponding to the maximum detection number, and the maximum detection is reached when the number of all detected DCIs reaches the maximum detection. When the number is reached, the PDCCH blind detection process is stopped.

Alternatively, if the DCIs of the N types corresponding to the terminal are respectively corresponding to a maximum detection number, when performing the PDCCH blind detection, the DCI of each type is respectively detected to detect whether the number of DCIs of the type currently detected is the same. The maximum number of detections corresponding to this category is reached, and whether to stop blind PDCCH detection is determined based on the detection results.

The implementation of stopping the PDCCH blind detection according to the detection result may be: stopping the PDCCH blind detection when the number of detected DCIs of any type reaches the maximum detection number corresponding to the type; or, it may also be: detecting When the number of DCIs of each type reaches the maximum number of detections corresponding to the type, the PDCCH blind detection is stopped; or, it may also be: the number of detected DCIs of at least type Y reaches the maximum detection number corresponding to the type, and then stop For PDCCH blind detection, Y is an integer greater than or equal to 1, and Y is less than the total number of categories N of the DCI.

The second type: the maximum number of detections received by the terminal for all DCIs or types of DCI is at least two. In the following, for ease of understanding, a case in which the maximum number of detections for all DCIs received by the terminal is at least two and the specified time-frequency resource range is determined is taken as an example to describe its specific implementation manner.

In this implementation scenario, the network device sends at least two maximum detection parameters to the terminal. Then, which specific maximum detection parameter is valid, that is, which maximum detection parameter can be used as the target detection parameter, and is used to guide the terminal to stop PDCCH blindness. The inspection process needs to be further determined by the following means:

The terminal determines the number of targets in at least one maximum detection number;

If the number of DCIs detected during the PDCCH blind detection process reaches the target number, the terminal stops the PDCCH blind detection.

The number of targets determined by the terminal may be determined based on the terminal.

In a feasible implementation manner, the terminal may determine the target number based on the working mode in which the terminal is located. At this time, referring to FIG. 5, S110 may specifically include the following steps:

S1102: The terminal obtains a working mode in which the terminal is located.

S1104: The terminal determines the target number according to the working mode.

S1106: If it is detected that the number of DCIs reaches the target number during the PDCCH blind detection process, the terminal stops the PDCCH blind detection.

The working mode of the terminal may include: an energy saving mode or a normal mode, wherein a maximum detection number of the normal mode is greater than a maximum detection number of the energy saving mode. Therefore, taking the terminal receiving two maximum detection parameters with different values as an example, when the terminal is in the normal mode, a maximum detection parameter with a larger value is determined as the target number; otherwise, when the terminal is in the energy-saving mode, the terminal A maximum detection parameter with a smaller value is determined as the number of targets.

In the embodiment of the present application, the manner in which the terminal determines the number of targets on its own can also be implemented in various other manners, which is not particularly limited in the embodiment of the present application. For example, the terminal may randomly select a maximum number of detections as the target number among the at least one maximum number of detections received. Or, for another example, the terminal may select a maximum detection number as the target number according to a preset order, such as a numerical value from small to large or from large to small. Or, for another example, the terminal may also randomly select the maximum number of detections with the smallest value among the at least one maximum number of detections as the target number according to the current power state.

In this implementation, there is no need for the network device to configure complicated instruction information or to send additional instruction information, and the terminal does not need to accept or demodulate the information, and compared to the network device, the terminal is more aware of its own energy consumption status. The self-determined number of targets can better meet their own energy consumption needs, and can further reduce the energy consumption of the terminal to a certain extent.

In another feasible implementation manner, the terminal may determine a target number based on an instruction of the network device. At this time, referring to FIG. 6, before executing S110, this may specifically include the following steps:

S109A2, the network device sends instruction information to the terminal.

In the embodiment of the present application, the indication information is used to instruct the terminal to stop blind PDCCH detection according to one target number among at least one maximum detection number.

The network device may send the indication information to the terminal by using the second control signaling. Among them, the second control signaling may include, but is not limited to, at least one of RRC signaling, MAC signaling, and DCI signaling.

In the embodiment of the present application, the first control signaling and the second control signaling may be the same control signaling. At this time, in a possible implementation scenario, the network device sends at least two maximum detection numbers to the terminal through the first control signaling, and the first control signaling carries indication information used to indicate the number of targets.

Alternatively, the first control signaling and the second control signaling may also be two different control signaling. At this time, when the two are different control signaling, the execution sequence of step S109A2 needs to be implemented at any timing before S110, which is not particularly limited in this application, and the process shown in FIG. 6 is only a feasible implementation. Is not intended to limit this application.

S109A4: The terminal receives the instruction information sent by the network device.

S109A6. The terminal determines the number of targets according to the instruction information.

At this time, S110 can be transformed into the following form;

S1106: If it is detected that the number of DCIs reaches the target number during the PDCCH blind detection process, the terminal stops the PDCCH blind detection.

That is, the terminal determines a maximum detection number indicated by the network device as the target number. In this implementation, both the network device and the terminal perform DCI transmission or reception according to the target number. The number of DCIs configured by the network device to the terminal and the number of DCIs received by the terminal match each other, preventing the network device from sending multiple DCIs. However, a situation in which the terminal receives only part of the DCI can avoid the problem of missing useful DCI information to a certain extent and ensure the stability of the communication.

In the embodiments of the present application, it is considered that the terminal's understanding of its own energy consumption status will be more comprehensive. In some special implementation scenarios, the terminal may or have its own desired detection parameters, where the expected detection parameters are used to indicate the maximum number of detections it expects. And / or maximum detection power.

At this time, the method may further include the following steps:

The terminal sends the desired detection parameter to the network device, so that the network device determines at least one maximum detection number or indicates a target number according to the expected detection parameter.

The network device receives a desired detection parameter sent by the terminal.

It should be noted that, in the embodiment of the present application, the execution order of the above two steps is not particularly limited. For example, these two steps can be performed before the target number is confirmed, so that the expected detection number can be used in the process of determining the target number by the network device; or, for example, if these two steps are applied before S102, the expected detection number is made It can act on the network device to configure at least one maximum detection number for the terminal. And, in the embodiment of the present application, there is no particular limitation on whether the network device performs the determination process of the number of targets or at least one maximum number of detections according to the desired detection number. For example, the network device may also use the terminal's expected detection parameters as a reference to guide the determination process of the number of targets or at least one maximum detection number; or the network device may still provide the terminal with the preset configuration rules for the terminal. Configure at least one maximum detection number and determine the number of targets. At this time, it is expected that the detection parameters have no effect on these two processes.

This embodiment of the present application provides a feasible implementation manner. Please refer to FIG. 7. The method includes the following steps:

S109B2, the terminal sends the desired detection parameter to the network device.

S109B4. The network device receives the desired detection parameter.

S109B6. The network device determines a target number among at least one maximum detection number according to the expected detection parameter.

S109B8: The network device sends the indication information for indicating the number of targets to the terminal.

S109B10: The terminal determines the target number according to the instruction information.

At this time, S110 can be transformed into the following form;

S1106: If it is detected that the number of DCIs reaches the target number during the PDCCH blind detection process, the terminal stops the PDCCH blind detection.

In some specific implementation scenarios, a corresponding relationship between the maximum number of detections expected by the terminal and the maximum expected detection power may be further established, and the correspondence may be stored in the terminal and / or the network device.

Taking the process shown in FIG. 7 as an example, if the correspondence is stored in the network device, and the terminal sends the maximum detection power expected by the terminal to the network device, the network device can determine the maximum detection number expected by the terminal based on the correspondence, so that During the execution of S109B4, if the maximum detection number expected by the terminal is one of the at least one maximum detection number sent to the terminal by the network device S104, the network device may directly determine the maximum detection number expected by the terminal as the target number; Alternatively, if the maximum detection number expected by the terminal is one of the at least one maximum detection number sent to the terminal by the network device S104, the network device may determine a maximum detection number whose value is less than the maximum detection number expected by the terminal as The number of goals.

It should also be noted that the information detection method provided in the embodiment of the present application can be used in combination with the solution of stopping the blind PDCCH detection by using the number of PDCCH candidate positions and / or the number of non-overlapping CCEs in the prior art. In specific implementation, as long as the terminal detects that any one of the following three conditions is satisfied, it can stop the blind PDCCH detection:

Reach the number of PDCCH candidates that need to be blindly detected;

Reach the number of non-overlap CCEs that require blind inspection;

The maximum number of DCIs that can be detected within the specified time-frequency resource range is reached.

The technical solutions provided in the embodiments of the present application have at least the following technical effects:

At least one maximum detection number configured and sent by the network device to the terminal, so that when the terminal performs blind PDCCH detection within a specified time-frequency resource range, the terminal can stop the PDCCH blind detection process when the number of detected DCI reaches the maximum detection number, That is, the number of DCIs within the specified time-frequency resource range directly affects the PDCCH blind detection process. The number of blind PDCCH detections by the terminal is reduced by limiting the number of DCIs, thereby achieving the technical effect of reducing the power consumption of the terminal.
