Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a scheduling method, apparatus, access network equipment and medium. Background Art

[0002] When scheduling terminal devices in a service cell, the access network device can determine the number of PDCCH (Physical Downlink Control Channel) symbols configured for the terminal devices in the service cell (i.e., the number of symbols occupied by the PDCCH) according to the number of terminal devices currently in an RRC (Radio Resource Control) connection state in the service cell. For example, when the number of terminal devices in an RRC connection state is relatively small, the CORESET (Control resource set) dedicated to users of the entire network can be reconfigured to 1 symbol (i.e., the CORESET occupies 1 symbol), and when the number of terminal devices in an RRC connection state is relatively large, the CORESET dedicated to users of the entire network can be reconfigured to 2 symbols (i.e., the CORESET occupies 2 symbols).

[0003] In the above scheme, when a CORESET occupying 1 symbol overlaps with a CORESET occupying 2 symbols, some resources will be wasted due to the time domain priority allocation method of the CORESET. Summary of the invention

[0065] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0066] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0067] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0068] The downlink time slot contains two resources: PDCCH and PDSCH (Physical Downlink Shared Channel) (i.e., the symbols in the downlink time slot include those occupied by PDCCH and those occupied by PDSCH). The access network device can notify the terminal devices in the serving cell of the CORESET and search space configuration used through RRC signaling. The two parameters, the number of symbols used by CORESET and the monitoring symbol position within the time slot in the search space (monitoringSymbolsWithinSlot), jointly determine the number of symbols allocated to PDCCH in the current time slot (i.e., the number of symbols required to be occupied by PDCCH).

[0069] In related technologies, the number of symbols required to be occupied by the PDCCH can be determined in the following ways:

[0070] The first method is to determine the number of PDCCH symbols configured for the terminal devices in the serving cell (i.e., the number of symbols occupied by PDCCH) according to the number of terminal devices currently in the RRC connected state in the serving cell. For example, when the number of terminal devices in the RRC connected state is relatively small, the dedicated CORESET for all users in the network can be reconfigured to 1 symbol (e.g. Figure 1 In the example, CORESET1 occupies 1 symbol. When the number of terminal devices in the RRC connection state is relatively large, the dedicated CORESET for all users in the network can be reconfigured into 2 symbols (such as Figure 1 CORESET2 in occupies 2 symbols).

[0071] The second method is to allocate 1 symbol dedicated CORESET to all terminal devices in the serving cell, and when the number of terminal devices in the RRC connected state is relatively small, all terminal devices are configured as follows: the symbol occupied by PDCCH is symbol #0 in the time slot ( Figure 2 When the number of terminal devices in the RRC connected state is relatively large, the terminal devices are grouped, and the terminal devices in one group are configured such that the symbol occupied by the PDCCH is symbol #0 in the time slot, and the terminal devices in the other group are configured such that the symbol occupied by the PDCCH is symbol #1 in the time slot ( Figure 2 CORESET2 in ).

[0072] It should be noted that Figure 1 and Figure 2 In the example, the horizontal direction is used to indicate each symbol in the time slot, and the vertical direction is used to indicate each PRB (Physical Resource Block, physical resource block), and, Figure 1 and Figure 2 In the example, only 16 PRBs are used. In actual applications, the number of PRBs is an integer multiple of 6.

[0073] The third method is to determine the number of symbols occupied by the PDCCH based on a periodically statistical CCE (Control Channel Element) occupancy rate method.

[0074] However, the first and second solutions mentioned above will have the problem of wasting resources.

[0075] For example, in the first solution, when the 1-symbol and 2-symbol CORESETs overlap, some resources will be wasted due to the CORESET time domain priority allocation method.

[0076] In the second solution, when the cell level uses 2-symbol PDCCH, the terminal devices need to be grouped. In extreme cases, it may happen that all the symbols scheduled in a time slot are symbol #1, and symbol #0 is vacant. In order to avoid the waste of resources caused by the imbalance of PDCCH resource usage, a more complex terminal grouping balancing and scheduling selection algorithm is required. The implementation is more complex and there is still a risk of resource waste.

[0077] In the third solution, a periodic statistical method is used, and the minimum granularity of the change in the number of symbols occupied by the PDCCH is the statistical period, which is not flexible enough.

[0078] Therefore, in order to solve at least one of the above-mentioned problems, the embodiments of the present application provide a scheduling method, device, access network equipment and medium, wherein the method and the device are based on the same application concept. Since the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0079] The scheduling method, apparatus, access network device and medium provided by the present application are described below with reference to the accompanying drawings. Before describing the embodiments of the present application in detail, for ease of understanding, common technical terms are first introduced:

[0080] The set value interval refers to a pre-set PDCCH resource occupancy value range, wherein the upper limit of the set value interval can be called the PDCCH resource occupancy high threshold (for example, marked as ρ_thr_high), and the lower limit of the set value interval can be called the PDCCH resource occupancy low threshold (for example, marked as ρ_thr_low).

[0081] The first terminal refers to any terminal device or all terminal devices within the service cell of the access network device.

[0082] The second terminal refers to a terminal device newly connected to the service cell of the access network device. At this time, the first terminal may include the second terminal.

[0083] The first symbol quantity refers to the number of symbols required to be occupied by the PDCCH carried by the first time slot when the first time slot is not the first time slot scheduled.

[0084] The second symbol quantity refers to the number of symbols occupied by the PDCCH carried by the second time slot.

[0085] The third number of symbols refers to the number of symbols required to be occupied by the PDCCH carried by the first time slot when the first time slot is the first time slot scheduled.

[0086] The first time slot may be, for example, the current time slot.

[0087] The second time slot refers to a time slot that is located before the first time slot and is of the same type as the first time slot. For example, the second time slot may be a time slot that is closest to the first time slot and is of the same type as the first time slot.

[0088] The third time slot refers to a time slot that is located before the second time slot and is of the same type as the second time slot. For example, the third time slot may be a time slot that is closest to the second time slot and is of the same type as the second time slot.

[0089] The fourth time slot refers to a time slot that is located before the third time slot and is of the same type as the third time slot. For example, the fourth time slot may be a time slot that is closest to the third time slot and is of the same type as the third time slot.

[0090] The first setting value is the value of the target flag bit, which is used to indicate that the number of symbols occupied by the PDCCH carried by two adjacent time slots of the same type is different. For example, the first setting value can be used to indicate that the number of symbols occupied by the PDCCH carried by the second time slot is different from the number of symbols occupied by the PDCCH carried by the third time slot, or the first setting value can be used to indicate that the number of symbols occupied by the PDCCH carried by the third time slot is different from the number of symbols occupied by the PDCCH carried by the fourth time slot.

[0091] The second setting value is the value of the target flag bit, which is used to indicate that the number of symbols occupied by the PDCCH carried by two adjacent time slots of the same type is the same. For example, the second setting value can be used to indicate that the number of symbols occupied by the PDCCH carried by the second time slot is the same as the number of symbols occupied by the PDCCH carried by the third time slot, or the second setting value can be used to indicate that the number of symbols occupied by the PDCCH carried by the third time slot is the same as the number of symbols occupied by the PDCCH carried by the fourth time slot.

[0092] For example, the first setting value may be 1, and the second setting value may be 0, or the first setting value may be 0, and the second setting value may be 1. It should be noted that the above first setting value and the second setting value are only exemplary descriptions, and the present application is not limited thereto. In actual application, the first setting value only needs to be different from the second setting value.

[0093] The first configuration value is the minimum number of symbols that the PDCCH configured by the access network device is allowed to occupy, that is, the minimum number of PDCCH symbols that can be configured. For example, the first configuration value may be 1.

[0094] The second configuration value is the maximum number of symbols that the PDCCH configured for the access network device is allowed to occupy, that is, the maximum number of PDCCH symbols that can be configured. For example, the value range of the second configuration value can be [1,3].

[0096] The scheduling method of the embodiment of the present application can be executed by an access network device.

[0097] Herein, the access network device is taken as an example as a base station. The base station may include multiple cells that provide services for the terminal device. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The access network device may be used to interchange received air frames with Internet Protocol (IP) packets, and serve as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The access network device may also coordinate the attribute management of the air interface. For example, the access network device involved in the embodiments of the present application may be an access network device (Base TransceiverStation, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or an access network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolutionary access network device (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a home evolved Node B (HeNB), a relay node, a home base station (femto), a pico base station (pico), etc., which is not limited in the embodiments of the present application. In some network structures, the access network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be arranged geographically separately.

[0098] The terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. In different systems, the names of the terminal devices may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). The wireless terminal device may communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA) and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, and a user device, but is not limited in the embodiments of the present application.

[0099] like Figure 3 As shown, the scheduling method may include the following steps:

[0100] Step S301, obtaining the actual PDCCH resource occupancy rate in the second time slot before the first time slot; wherein the type of the first time slot is the same as the type of the second time slot, and the type is divided according to the PDCCH carried by the time slot.

[0101] In an embodiment of the present application, the type of time slot can be divided according to the PDCCH carried by the time slot. For example, when the PDCCH carried by a time slot only includes a downlink PDCCH, the type of the time slot can be the first type, and when the PDCCH carried by the time slot includes a downlink PDCCH and an uplink PDCCH, the type of the time slot can be the second type.

[0102] Among them, the downlink PDCCH is used to schedule downlink service channels, and the uplink PDCCH is used to schedule uplink service channels.

[0103] In the embodiment of the present application, the actual PDCCH resource occupancy rate (instantaneous value) of a second time slot that is located before the first time slot and is of the same type as the first time slot may be obtained.

[0104] Step S302: Determine the predicted PDCCH resource occupancy rate in the first time slot according to the type of the second time slot and the actual PDCCH resource occupancy rate in the second time slot.

[0105] In an embodiment of the present application, the predicted PDCCH resource occupancy (or estimated PDCCH resource occupancy) in the first time slot can be estimated or calculated based on the type of the second time slot (such as the first type or the second type) and the actual PDCCH resource occupancy in the second time slot.

[0106] Step S303: determining the number of first symbols required to be occupied by the PDCCH carried in the first time slot according to the predicted PDCCH resource occupancy rate in the first time slot.

[0107] In an embodiment of the present application, the number of symbols (referred to as the first number of symbols in the present application) required to be occupied by the PDCCH carried by the first time slot can be calculated based on the predicted PDCCH resource occupancy rate in the first time slot.

[0108] In a possible implementation method of an embodiment of the present application, the method for calculating the first symbol number is, for example: obtaining the second symbol number occupied by the PDCCH carried by the second time slot, and determining the first symbol number based on the second symbol number and the predicted PDCCH resource occupancy rate in the first time slot.

[0109] As an example, when the predicted PDCCH resource occupancy rate in the first time slot is relatively small, the second number of symbols may be reduced to obtain the first number of symbols.

[0110] As another possible implementation, when the predicted PDCCH resource occupancy rate in the first time slot is relatively large, the second symbol number may be increased to obtain the first symbol number, thereby improving the resource occupancy rate and avoiding resource waste.

[0111] Step S304: Schedule the first terminal in the serving cell in the first time slot according to the first number of symbols.

[0112] In an embodiment of the present application, the first terminal in the service cell of the access network device can be scheduled in the first time slot according to the first number of symbols.

[0113] As a possible implementation manner, the scheduling manner, for example, is: according to the first symbol quantity, determine the starting symbol position corresponding to the PDSCH carried by the first time slot, for example, assuming that the first symbol quantity is M (that is, the symbols available for PDCCH are: symbol #0, #1, ..., #M-1), the symbols available for PSDCH are: symbol #M, #M+1, ..., that is, the starting symbol position can be M. The access network device can send the PDCCH carried by the first time slot to the first terminal in the serving cell, wherein the PDCCH carried by the first time slot is used to carry DCI (Downlink Control Information, downlink control information), and the DCI is used to indicate the starting symbol position.

[0114] The scheduling method of the embodiment of the present application obtains the actual PDCCH resource occupancy rate in the second time slot before the first time slot; determines the predicted PDCCH resource occupancy rate in the first time slot according to the type of the second time slot and the actual PDCCH resource occupancy rate in the second time slot; determines the first number of symbols required to be occupied by the PDCCH carried in the first time slot according to the predicted PDCCH resource occupancy rate in the first time slot; and schedules the first terminal in the service cell in the first time slot according to the first number of symbols. Thus, it is possible to determine the predicted (or estimated) PDCCH resource occupancy rate of the first time slot according to the actual PDCCH resource occupancy rate and time slot type of the second time slot of the same type as the first time slot, thereby determining the number of symbols required to be occupied by the PDCCH carried in the first time slot according to the predicted (or estimated) PDCCH resource occupancy rate of the first time slot, thereby improving resource utilization.

[0115] In order to clearly explain how to obtain the actual PDCCH resource occupancy rate in the second time slot in any embodiment of the present application, the present application also proposes a scheduling method.

[0116] Figure 4 A flowchart of another scheduling method provided in an embodiment of the present application.

[0117] like Figure 4 As shown, the scheduling method can be executed by an access network device and may include the following steps:

[0118] Step S401: Acquire the number of second symbols occupied by the PDCCH carried by the second time slot.

[0119] The type of the second time slot is the same as the type of the first time slot, and the time slot type is divided according to the PDCCH carried by the time slot.

[0120] In an embodiment of the present application, the second time slot is a scheduled time slot, and the number of symbols occupied by the PDCCH carried by the second time slot (referred to as the second number of symbols in this application) is known. Therefore, the access network device can obtain the second number of symbols occupied by the PDCCH carried by the second time slot.

[0121] Step S402, obtaining a first number of CCEs included in a CORESET; wherein the CORESET occupies a single symbol.

[0122] In the embodiment of the present application, the above-mentioned CORESET can be called a single-symbol CORESET, which is a CORESET allocated or configured by the access network device to the first terminal or the second terminal in the service cell.

[0123] In an embodiment of the present application, the access network device can obtain the number of CCEs included in the CORESET (recorded as the first number in the present application).

[0124] Step S403: Acquire a second number of CCEs allocated by the access network device in the second time slot.

[0125] In an embodiment of the present application, the access network device can obtain the number of CCEs allocated to it in the second time slot (referred to as the second number in the present application).

[0126] Step S404: determining an actual PDCCH resource occupancy rate in the second time slot according to the second number, the first number and the second number of symbols.

[0127] In the embodiment of the present application, the actual PDCCH resource occupancy rate in the second time slot may be determined according to the second number, the first number, and the second number of symbols.

[0128] Among them, the actual PDCCH resource occupancy rate in the second time slot is positively correlated with the second number, and the actual PDCCH resource occupancy rate in the second time slot is negatively correlated with the first number, and the actual PDCCH resource occupancy rate in the second time slot is negatively correlated with the second symbol number.

[0129] In a possible implementation method of an embodiment of the present application, the actual PDCCH resource occupancy rate in the second time slot is calculated, for example, by determining an intermediate coefficient based on the product of the first number and the second number of symbols, and determining the actual PDCCH resource occupancy rate in the second time slot based on the ratio of the second number to the intermediate coefficient.

[0130] As an example, the actual PDCCH resource occupancy rate in the second time slot is marked as p_current, the second number is N_alloc_CCE, the first number is N_CCE_single_sym, and the second symbol number is PDCCH_sym, then:

[0131] ρ_current=N_alloc_CCE / (PDCCH_sym*N_CCE_single_sym); (1)

[0132] Step S405: Determine the predicted PDCCH resource occupancy rate in the first time slot according to the type of the second time slot and the actual PDCCH resource occupancy rate in the second time slot.

[0133] Step S406: Determine the number of first symbols required to be occupied by the PDCCH carried in the first time slot according to the predicted PDCCH resource occupancy rate in the first time slot.

[0134] Step S407: Schedule the first terminal in the serving cell in the first time slot according to the first symbol quantity.

[0135] Steps S405 to S407 may be implemented in any manner in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0136] The scheduling method of the embodiment of the present application can effectively calculate the actual PDCCH resource occupancy rate in the second time slot based on the number of second symbols occupied by the PDCCH carried by the scheduled second time slot, the number of CCEs contained in the single-symbol CORESET, and the number of CCEs allocated in the second time slot, thereby improving the effectiveness of obtaining the actual PDCCH resource occupancy rate in the second time slot.

[0137] In order to clearly explain how any embodiment of the present application calculates the predicted PDCCH resource occupancy rate in the first time slot according to the type of the second time slot and the actual PDCCH resource occupancy rate in the second time slot, the present application also proposes a scheduling method.

[0138] Figure 5 A flowchart of another scheduling method provided in an embodiment of the present application.

[0139] like Figure 5 As shown, the scheduling method can be executed by an access network device and may include the following steps:

[0140] Step S501: Acquire the actual PDCCH resource occupancy rate in the second time slot before the first time slot.

[0141] The type of the first time slot is the same as the type of the second time slot, and the type is divided according to the PDCCH carried by the time slot.

[0142] Step S501 can be implemented in any way in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0143] Step S502: Obtain the value of the target flag bit associated with the type of the second time slot in the second time slot.

[0144] Among them, the target flag bit under the second time slot is used to indicate whether the number of symbols occupied by the PDCCH carried by the second time slot and the third time slot is the same, and the third time slot is a time slot located before the second time slot and of the same type as the second time slot.

[0145] In the embodiment of the present application, the value of the target flag bit associated with the type of the second time slot in the second time slot can be obtained.

[0146] As an example, when the type of the second time slot is the first type, the target flag bit associated with the first type may be PDCCH_sym_change_flag_1.

[0147] As another example, when the type of the second time slot is the second type, the target flag bit associated with the second type may be PDCCH_sym_change_flag_2. That is, the target flag bit associated with the first type is different from the target flag bit associated with the second type.

[0148] Step S503, when the value of the target flag bit in the second time slot is the first set value, the actual PDCCH resource occupancy rate in the second time slot is used as the predicted PDCCH resource occupancy rate in the first time slot.

[0149] The first setting value is used to indicate that the number of symbols occupied by the PDCCH carried by the second time slot and the third time slot is different.

[0150] In an embodiment of the present application, when the value of the target flag bit in the second time slot is the first set value, that is, the number of symbols occupied by the PDCCH carried by the second time slot is different from the number of symbols occupied by the PDCCH carried by the third time slot, at this time, the actual PDCCH resource occupancy rate in the second time slot can be used as the predicted PDCCH resource occupancy rate in the first time slot.

[0151] Step S504: determining the number of first symbols required to be occupied by the PDCCH carried in the first time slot according to the predicted PDCCH resource occupancy rate in the first time slot.

[0152] Step S505: Schedule the first terminal in the serving cell in the first time slot according to the first symbol quantity.

[0153] Steps S504 to S505 may be implemented in any manner in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0154] In any embodiment of the present application, when there is no scheduled time slot of the same type before the first time slot, such as when the first time slot is the first time slot to be scheduled, the number of symbols (referred to as the third number of symbols in the present application) required to be occupied by the PDCCH carried by the first time slot can be determined based on the set number of symbols (i.e., the configured initial number of symbols), so that the first terminal in the service cell can be scheduled in the first time slot based on the third number of symbols.

[0155] As an example, the starting symbol position corresponding to the PDSCH carried by the first time slot may be determined according to the third symbol quantity. For example, assuming that the third symbol quantity is N (that is, the symbols available for PDCCH are: symbol #0, #1, ..., #N-1), the symbols available for PSDCH are: symbol #N, #N+1, ..., that is, the starting symbol position may be N. The access network device may send the PDCCH carried by the first time slot to the first terminal in the serving cell, wherein the PDCCH carried by the first time slot is used to carry DCI, and the DCI is used to indicate the starting symbol position.

[0156] The scheduling method of the embodiment of the present application can effectively calculate the predicted PDCCH resource occupancy rate in the first time slot according to the value of the target flag bit associated with the time slot type of the second time slot in the second time slot and the actual PDCCH resource occupancy rate in the second time slot.

[0157] In order to clearly explain how any embodiment of the present application calculates the predicted PDCCH resource occupancy rate in the first time slot according to the type of the second time slot and the actual PDCCH resource occupancy rate in the second time slot, the present application also proposes a scheduling method.

[0158] Figure 6 A flowchart of another scheduling method provided in an embodiment of the present application.

[0159] like Figure 6 As shown, the scheduling method can be executed by an access network device and may include the following steps:

[0160] Step S601: Acquire the actual PDCCH resource occupancy rate in the second time slot before the first time slot.

[0161] The type of the first time slot is the same as the type of the second time slot, and the type is divided according to the PDCCH carried by the time slot.

[0162] Step S602: Obtain the value of the target flag bit associated with the type of the second time slot in the second time slot.

[0163] Among them, the target flag bit under the second time slot is used to indicate whether the number of symbols occupied by the PDCCH carried by the second time slot and the third time slot is the same, and the third time slot is a time slot located before the second time slot and of the same type as the second time slot.

[0164] Steps S601 to S602 may be implemented in any manner in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0165] Step S603, when the value of the target flag bit in the second time slot is a second set value, obtain the predicted PDCCH resource occupancy rate in the second time slot.

[0166] The second setting value is used to indicate that the number of symbols occupied by the PDCCH carried by the second time slot and the third time slot is the same.

[0167] In an embodiment of the present application, when the value of the target flag bit in the second time slot is the second set value, that is, the number of symbols occupied by the PDCCH carried by the second time slot is the same as the number of symbols occupied by the PDCCH carried by the third time slot, at this time, the predicted PDCCH resource occupancy rate in the second time slot can be further obtained.

[0168] The predicted PDCCH resource occupancy rate in the second time slot may be determined according to the type of the third time slot and the actual PDCCH resource occupancy rate in the third time slot.

[0169] That is, each time slot may include two PDCCH resource occupancy rates, one of which is an actual PDCCH resource occupancy rate, and the other is a predicted or estimated PDCCH resource occupancy rate.

[0170] As a possible implementation manner, according to the type of the third time slot and the actual PDCCH resource occupancy rate in the third time slot, a specific manner of determining the predicted PDCCH resource occupancy rate in the second time slot is, for example:

[0171] First, the value of the target flag bit in the third time slot can be obtained; wherein, when the third time slot is the first time slot, the value of the target flag bit in the third time slot is a first set value, and when the third time slot is not the first time slot, the value of the target flag bit in the third time slot is determined according to whether the number of symbols occupied by the PDCCH carried by the third time slot and the fourth time slot are the same. For example, when the number of symbols occupied by the PDCCH carried by the third time slot is different from the number of symbols occupied by the PDCCH carried by the fourth time slot, the value of the target flag bit in the third time slot is the first set value, and when the number of symbols occupied by the PDCCH carried by the third time slot is the same as the number of symbols occupied by the PDCCH carried by the fourth time slot, the value of the target flag bit in the third time slot is the second set value; wherein the fourth time slot is a time slot located before the third time slot and of the same type as the third time slot.

[0172] When the value of the target flag bit in the third time slot is the first set value, the actual PDCCH resource occupancy rate in the third time slot may be used as the predicted PDCCH resource occupancy rate in the second time slot.

[0173] When the value of the target flag bit in the third time slot is the second set value, the predicted PDCCH resource occupancy rate in the second time slot can be determined according to the predicted PDCCH resource occupancy rate in the third time slot and the actual PDCCH resource occupancy rate in the third time slot. For example, the predicted PDCCH resource occupancy rate in the third time slot and the actual PDCCH resource occupancy rate in the third time slot can be weighted and summed according to the configuration weight to obtain the predicted PDCCH resource occupancy rate in the second time slot.

[0174] It should be noted that the calculation method of the predicted PDCCH resource occupancy rate in the second time slot is similar to the calculation method of the predicted PDCCH resource occupancy rate in the first time slot in the subsequent step S604, and will not be described in detail here.

[0175] Step S604: determining the predicted PDCCH resource occupancy rate in the first time slot according to the predicted PDCCH resource occupancy rate in the second time slot and the actual PDCCH resource occupancy rate in the second time slot.

[0176] In the embodiment of the present application, the predicted PDCCH resource occupancy rate in the first time slot may be calculated according to the predicted PDCCH resource occupancy rate in the second time slot and the actual PDCCH resource occupancy rate in the second time slot.

[0177] As a possible implementation method, the method for calculating the predicted PDCCH resource occupancy rate in the first time slot is, for example: according to the configuration weight, the predicted PDCCH resource occupancy rate in the second time slot and the actual PDCCH resource occupancy rate in the second time slot are weighted summed to obtain the predicted PDCCH resource occupancy rate in the first time slot.

[0178] As an example, when the type of the second time slot is the first type, the tag configuration weight is α, the actual PDCCH resource occupancy rate in the second time slot is ρ_current, and the predicted PDCCH resource occupancy rate in the second time slot is ρ 1 ', the predicted PDCCH resource occupancy rate in the first time slot is p 1 , then:

[0179] ρ 1 =(1-α)*ρ 1 '+α*ρ_current; (2)

[0180] As another example, when the type of the second time slot is the second type, the tag configuration weight is α, the actual PDCCH resource occupancy rate in the second time slot is ρ_current, and the predicted PDCCH resource occupancy rate in the second time slot is ρ' 2 , the predicted PDCCH resource occupancy rate in the first time slot is ρ 2 , then:

[0181] ρ 2 =(1-α)*ρ' 2 +α*ρ_current; (3)

[0182] Step S605: determining the number of first symbols required to be occupied by the PDCCH carried in the first time slot according to the predicted PDCCH resource occupancy rate in the first time slot.

[0183] Step S606: Schedule the first terminal in the serving cell in the first time slot according to the first number of symbols.

[0184] Steps S605 to S606 may be implemented in any manner in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0185] As an example, the first setting value is 1, the second setting value is 0, the type of the second time slot is the first type, the target flag bit associated with the first type is PDCCH_sym_change_flag_1, and the initial value of PDCCH_sym_change_flag_1 is 1. The following steps can be used to determine the number of symbols required to be occupied by the PDCCH carried by each time slot:

[0186] 1. For the first time slot of the first type scheduled (hereinafter referred to as the first time slot), the number of time slots required to be occupied by the PDCCH carried by the first time slot is the set number of symbols, and the terminal equipment in the service cell can be scheduled according to the set number of symbols. At the end of the first time slot scheduling, the actual PDCCH resource occupancy rate of the first time slot can be calculated.

[0187] 2. For the second time slot of the first type scheduled (hereinafter referred to as the second time slot), since the value of the target flag bit (i.e., the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_1 associated with the first type in the first time slot is the configured initial value 1, the predicted PDCCH resource occupancy rate of the second time slot is ρ 1 = ...

[0188] Furthermore, it can be determined whether the number of symbols occupied by the PDCCH carried by the first time slot is the same as the number of symbols occupied by the PDCCH carried by the second time slot. If they are the same, PDCCH_sym_change_flag_1 in the second time slot is set to 0; if they are different, PDCCH_sym_change_flag_1 in the second time slot is set to 1.

[0189] After the time slot scheduling of the second time slot is completed, the actual PDCCH resource occupancy rate of the second time slot may be calculated.

[0190] 3. For the third first-type time slot (hereinafter referred to as the third time slot), first, it can be determined whether the value of PDCCH_sym_change_flag_1 in the second time slot is 0. If PDCCH_sym_change_flag_1 in the second time slot is 0, then the predicted PDCCH resource occupancy rate of the third time slot is ρ 1 =(1-α)*ρ 1 '+α*ρ_current, where ρ 1 ' represents the predicted PDCCH resource occupancy rate of the second time slot, and ρ_current represents the actual PDCCH resource occupancy rate of the second time slot. If PDCCH_sym_change_flag_1=1 in the second time slot, then the predicted PDCCH resource occupancy rate of the third time slot is ρ 1 =ρ_current. Then, the predicted PDCCH resource occupancy rate ρ of the third time slot can be 1, determine the number of symbols required to be occupied by the PDCCH carried by the third time slot, so as to schedule the terminal equipment in the service cell according to the number of symbols.

[0191] Furthermore, it can be determined whether the number of symbols occupied by the PDCCH carried by the second time slot is the same as the number of symbols occupied by the PDCCH carried by the third time slot. If they are the same, PDCCH_sym_change_flag_1 in the third time slot is set to 0; if they are different, PDCCH_sym_change_flag_1 in the third time slot is set to 1.

[0192] After the scheduling of the third time slot is completed, the actual PDCCH resource occupancy rate of the third time slot may be calculated.

[0193] 4. The scheduling process of subsequent time slots is similar to that of the second and third time slots, and will not be listed here one by one.

[0194] As another example, the first setting value is 1, the second setting value is 0, the type of the second time slot is the second type, the target flag bit associated with the second type is PDCCH_sym_change_flag_2, and the initial value of PDCCH_sym_change_flag_2 is 1. The following steps can be used to determine the number of symbols required to be occupied by the PDCCH carried by each time slot:

[0195] 1. For the first second type of time slot scheduled (hereinafter referred to as the first time slot), the number of time slots required to be occupied by the PDCCH carried by the first time slot is the set number of symbols, and the terminal devices in the service cell can be scheduled according to the set number of symbols. At the end of the first time slot scheduling, the actual PDCCH resource occupancy rate of the first time slot can be calculated.

[0196] 2. For the second time slot of the second type scheduled (hereinafter referred to as the second time slot), since the value of the target flag bit (i.e., the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_2 associated with the second type in the first time slot is the configured initial value 1, the predicted PDCCH resource occupancy rate of the second time slot is ρ 2 = ...

[0197] Furthermore, it can be determined whether the number of symbols occupied by the PDCCH carried by the first time slot is the same as the number of symbols occupied by the PDCCH carried by the second time slot. If they are the same, PDCCH_sym_change_flag_2 in the second time slot is set to 0; if they are different, PDCCH_sym_change_flag_2 in the second time slot is set to 1.

[0198] After the time slot scheduling of the second time slot is completed, the actual PDCCH resource occupancy rate of the second time slot may be calculated.

[0199] 3. For the third time slot of the second type scheduled (hereinafter referred to as the third time slot), first, it can be determined whether the value of PDCCH_sym_change_flag_2 in the second time slot is 0. If PDCCH_sym_change_flag_2 in the second time slot = 0, then the predicted PDCCH resource occupancy rate of the third time slot is ρ 2 =(1-α)*ρ' 2 +α*ρ_current, where ρ' 2 represents the predicted PDCCH resource occupancy rate of the second time slot, and ρ_current represents the actual PDCCH resource occupancy rate of the second time slot. If PDCCH_sym_change_flag_2=1 in the second time slot, then the predicted PDCCH resource occupancy rate of the third time slot is ρ 2 =ρ_current. Then, the predicted PDCCH resource occupancy rate ρ of the third time slot can be 2 , determine the number of symbols required to be occupied by the PDCCH carried by the third time slot, so as to schedule the terminal equipment in the service cell according to the number of symbols.

[0200] Furthermore, it can be determined whether the number of symbols occupied by the PDCCH carried by the second time slot is the same as the number of symbols occupied by the PDCCH carried by the third time slot. If so, PDCCH_sym_change_flag_2 in the third time slot is set to 0; if not, PDCCH_sym_change_flag_2 in the third time slot is set to 1.

[0201] After the scheduling of the third time slot is completed, the actual PDCCH resource occupancy rate of the third time slot may be calculated.

[0202] 4. The scheduling process of subsequent time slots is similar to that of the second and third time slots, and will not be listed here one by one.

[0203] The scheduling method of the embodiment of the present application can predict the predicted PDCCH resource occupancy rate in the first time slot in a smoothing manner, thereby improving the reliability of the calculation of the predicted PDCCH resource occupancy rate in the first time slot.

[0204] In order to clearly explain how any embodiment of the present application determines the number of first symbols required to be occupied by the PDCCH carried in the first time slot based on the predicted PDCCH resource occupancy rate in the first time slot, the present application also proposes a scheduling method.

[0205] Figure 7 A flowchart of another scheduling method provided in an embodiment of the present application.

[0206] like Figure 7 As shown, the scheduling method can be executed by an access network device and may include the following steps:

[0207] Step S701: Acquire the actual PDCCH resource occupancy rate in the second time slot before the first time slot.

[0208] The type of the first time slot is the same as the type of the second time slot, and the type is divided according to the PDCCH carried by the time slot.

[0209] Step S702: Determine the predicted PDCCH resource occupancy rate in the first time slot according to the type of the second time slot and the actual PDCCH resource occupancy rate in the second time slot.

[0210] Steps S701 to S702 may be implemented in any manner in the embodiments of the present application, and the embodiments of the present application do not limit this and will not be described in detail.

[0211] Step S703, determining whether the predicted PDCCH resource occupancy rate in the first time slot is within a set value range, if so, executing step S704, if not, executing step S705.

[0212] In the embodiment of the present application, the value interval is set to be a pre-set or configured value range.

[0213] In an embodiment of the present application, the predicted PDCCH resource occupancy rate in the first time slot can be compared with the set value range to determine whether the predicted PDCCH resource occupancy rate in the first time slot is within the set value range. If so, execute step S704; if not, execute step S705.

[0214] It should be noted that step S704 and step S705 are two parallel implementation methods. In actual application, only one needs to be executed.

[0215] Step S704: taking the second number of symbols occupied by the PDCCH carried by the second time slot as the first number of symbols.

[0216] In an embodiment of the present application, when the predicted PDCCH resource occupancy rate in the first time slot is within a set value range, the second number of symbols occupied by the PDCCH carried by the second time slot may be used as the first number of symbols.

[0217] Step S705: adjust the second symbol quantity to obtain the first symbol quantity.

[0218] In an embodiment of the present application, when the predicted PDCCH resource occupancy rate in the first time slot is not within a set value range, the second number of symbols can be adjusted to obtain the first number of symbols.

[0219] As a possible implementation method, the adjustment method of the first symbol number is, for example: when the predicted PDCCH resource occupancy rate in the first time slot is less than the lower limit of the set value range, it indicates that the PDCCH resource occupancy rate in the first time slot is relatively low. At this time, in order to improve resource utilization, the second symbol number can be reduced to obtain the first symbol number.

[0220] As an example, when the predicted PDCCH resource occupancy rate in the first time slot is less than the lower limit of the set value range, the second symbol number can be reduced according to the set adjustment step size (for example, 1) to obtain the first reference symbol number, and the first symbol number is determined based on the maximum value between the first configuration value and the first reference symbol number, wherein the first configuration value is used to indicate the minimum number of symbols allowed to be occupied by PDCCH.

[0221] Take the first configuration value and the setting adjustment step size as 1 for example, assuming that the number of symbols occupied by the PDCCH carried by the second time slot is N i ', the number of symbols occupied by the PDCCH carried by the first time slot is N i , then:

[0222] N i =max(1,N i '-1); (4)

[0223] As another possible implementation method, the method for adjusting the first symbol number is, for example: when the predicted PDCCH resource occupancy rate in the first time slot is greater than the upper limit of the set value range, it indicates that the PDCCH resource occupancy rate in the first time slot is relatively high. At this time, in order to improve the rationality of resource allocation, the second symbol number can be increased to obtain the first symbol number.

[0224] As an example, when the predicted PDCCH resource occupancy rate in the first time slot is greater than the upper limit of the set value range, the second symbol number can be increased according to the set adjustment step size to obtain the second reference symbol number, and the first symbol number can be determined based on the minimum value between the second reference symbol number and the second configuration value; wherein the second configuration value is used to indicate the maximum number of symbols allowed to be occupied by PDCCH.

[0225] Taking the adjustment step size as 1 as an example, assuming that the number of symbols occupied by the PDCCH carried by the second time slot is N i ', the second configuration value is N_max, the number of symbols occupied by the PDCCH carried by the first time slot is N i , then:

[0226] N i =min(N_max,N i '+1); (5)

[0227] Step S706: Schedule the first terminal in the serving cell in the first time slot according to the first number of symbols.

[0228] Step S706 can be implemented in any of the embodiments of the present application. The embodiments of the present application do not limit this and will not be described in detail.

[0229] In any embodiment of the present application, the access network device can also configure a CORESET for the newly accessed second terminal when monitoring the access of the second terminal, wherein the CORESET occupies a single symbol and generates a search space configuration based on the second configuration value, so that RRC signaling can be sent to the second terminal, so that the second terminal monitors the search space whose starting symbol position is less than the second configuration value according to the CORESET and search space configuration in the RRC signaling.

[0230] For example, if the second configuration value is marked as N_max, the second terminal can monitor the search space with the starting symbol #0 to N_max-1 according to the RRC signaling.

[0231] The scheduling method of the embodiment of the present application can jointly determine the number of first symbols required to be occupied by the PDCCH carried by the first time slot based on the number of second symbols occupied by the PDCCH carried by the second time slot and the predicted PDCCH resource occupancy rate in the first time slot, thereby improving the reliability of determining the number of first symbols.

[0232] In any embodiment of the present application, the number of symbols used or occupied by the PDCCH in the scheduling process may be adaptively determined by the following steps:

[0233] Step 1: According to the terminal quantity planning, set the maximum number of symbols that the PDCCH is allowed to occupy or use (recorded as the second configuration value in this application, for example, marked as N_max). According to the current protocol, the value range of N_max is 1 to 3. In addition, two PDCCH resource occupancy rate thresholds ρ_thr_low (recorded as the lower limit of the value interval in this application) and ρ_thr_high (recorded as the upper limit of the value interval in this application) can be set.

[0234] Step 2: When a new terminal device (referred to as the second terminal in this application) accesses, a single-symbol CORESET (i.e., CORESET occupies a single symbol) can be configured for the second terminal, and a search space with a monitoring start symbol position of #0 to N_max-1 can be configured. For example, a single-symbol CORESET can be configured as follows: Figure 8 The single symbol CORESET1 is shown.

[0235] It should be noted that Figure 8 In the example, the horizontal direction is used to indicate each symbol in the time slot, the vertical direction is used to indicate each PRB, and, Figure 8 The number of PRBs is 16 for example only. In actual application, the number of PRBs is an integer multiple of 6.

[0236] Step 3: Divide the downlink time slots into two categories: time slots that only carry downlink PDCCH (i.e., time slots of the first type); time slots that carry downlink PDCCH and uplink PDCCH (i.e., time slots of the second type). The downlink PDCCH is the PDCCH that schedules the downlink service channel, and the uplink PDCCH is the PDCCH that schedules the uplink service channel. The predicted (or estimated) PDCCH resource occupancy rates for the two types of time slots are calculated separately: The predicted (or estimated) PDCCH resource occupancy rate of the first type of time slots ρ 1 , the predicted (or estimated) PDCCH resource occupancy rate of the second type of time slots ρ 2 .

[0237] The initial number of symbols occupied by the PDCCH carried by the two types of time slots is set as follows: the initial number of symbols occupied by the PDCCH carried by the first type of time slot is N 1 =1, the number of initial symbols N that the PDCCH carried by the second type of time slot needs to occupy 2 =1; the target flag bit associated with the first type (ie, the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_1 = 1 (initial value), and the target flag bit associated with the second type PDCCH_sym_change_flag_2 = 1 (initial value).

[0238] Step 4: When the PDCCH scheduling in the time slot starts, execute step 5; when the PDCCH scheduling in the time slot ends, execute step 6.

[0239] For the time slots carrying downlink PDCCH and uplink PDCCH, it is necessary to wait until both uplink and downlink scheduling are completed before executing step 6.

[0240] Step 5: When the time slot scheduling starts, the number of symbols required to be occupied by the PDCCH carried by the time slot is determined in the following manner.

[0241] If the current time slot is a time slot that only carries downlink PDCCH (i.e., a time slot of the first type), the number of symbols that the PDCCH carried by the current time slot needs to occupy is PDCCH_sym=N 1 .

[0242] If the current time slot is a time slot that carries downlink PDCCH and uplink PDCCH, the number of symbols that the PDCCH carried by the current time slot needs to occupy is PDCCH_sym=N 2 .

[0243] After the number of symbols required to be occupied by the PDCCH is determined, it may be indicated in the DCI that the PDSCH whose starting symbol position is the symbol #PDCCH_sym is used for downlink scheduling.

[0244] Step 6: After the time slot scheduling is completed, the actual PDCCH resource occupancy rate of the current time slot is updated, and the number of symbols required to be occupied by the PDCCH carried by the next time slot is determined.

[0245] The actual PDCCH resource occupancy rate of the current time slot is ρ_current = N_alloc_CCE / (PDCCH_sym*N_CCE_single_sym), where N_alloc_CCE is the number of CCEs allocated to the current time slot, PDCCH_sym is the number of available symbols in the current time slot (i.e., the number of symbols occupied by the PDCCH carried by the current time slot), and N_CCE_single_sym is the number of CCEs contained in the single-symbol CORESET.

[0246] Step 6.1: Update the predicted PDCCH resource occupancy rate of the next time slot.

[0247] 1. If the current time slot is a time slot of the first type (i.e., a time slot that only carries downlink PDCCH), determine whether the target flag bit associated with the first type (i.e., the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_1 is 0 (i.e., the current time slot is the same as the PDCCH_sym of the most recent first type time slot).

[0248] 2. If the target flag associated with the first type is PDCCH_sym_change_flag_1 = 0, update p 1 =(1-α)*ρ 1 '+α*ρ_current.

[0249] Among them, ρ 1 represents the predicted PDCCH resource occupancy rate of the next time slot, ρ 1 ' indicates the predicted PDCCH resource occupancy rate of the current time slot. α is configured externally and its value range is [0,1].

[0250] 3. If the target flag associated with the first type is PDCCH_sym_change_flag_1 = 1, update ρ 1 =ρ_current.

[0251] For example, for the first time slot of the first type scheduled (hereinafter referred to as the first time slot), PDCCH_sym of the first time slot is 1 (ie, the number of initial symbols configured N 1 ). At the end of the first time slot scheduling, the actual PDCCH resource occupancy of the first time slot can be calculated.

[0252] For the second first-type time slot scheduled (hereinafter referred to as the second time slot), since the value of the target flag bit (i.e., the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_1 associated with the first type is the configured initial value 1, the predicted PDCCH resource occupancy rate of the second time slot is ρ 1 = ... 1 , determine the PDCCH_sym of the second time slot.

[0253] Furthermore, it can be determined whether the PDCCH_sym of the first time slot is the same as the PDCCH_sym of the second time slot. If they are the same, PDCCH_sym_change_flag_1 = 0. If they are different, PDCCH_sym_change_flag_1 = 1. After the time slot scheduling of the second time slot is completed, the actual PDCCH resource occupancy of the second time slot can be calculated.

[0254] For the third time slot of the first type scheduled (hereinafter referred to as the third time slot), determine whether the value of PDCCH_sym_change_flag_1 is 0. If PDCCH_sym_change_flag_1=0, set the value of ρ of the third time slot to 1 =(1-α)*ρ 1'+α*ρ_current, where ρ 1 ' represents the predicted PDCCH resource occupancy rate of the second time slot, and ρ_current represents the actual PDCCH resource occupancy rate of the second time slot. If PDCCH_sym_change_flag_1=1, then let ρ of the third time slot 1 =ρ_current. The subsequent step 6.2 can be adopted to calculate the value of ρ in the third time slot. 1 , determine the PDCCH_sym of the third time slot.

[0255] Furthermore, it can be determined whether the PDCCH_sym of the second time slot is the same as the PDCCH_sym of the third time slot. If they are the same, PDCCH_sym_change_flag_1 = 0. If they are different, PDCCH_sym_change_flag_1 = 1. After the scheduling of the third time slot is completed, the actual PDCCH resource occupancy of the third time slot can be calculated.

[0256] The scheduling process of subsequent time slots is similar to that of the second time slot and the third time slot, and is not listed here one by one.

[0257] 4. If the current time slot is a time slot of the second type (i.e., a time slot carrying downlink PDCCH and uplink PDCCH), determine whether the target flag bit associated with the second type (i.e., the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_2 is 0 (i.e., the current time slot is the same as the PDCCH_sym of the most recent first type time slot).

[0258] 5. If the target flag associated with the second type is PDCCH_sym_change_flag_2 = 0, update p 2 =(1-α)*ρ' 2 +α*ρ_current.

[0259] Among them, ρ 2 represents the predicted PDCCH resource occupancy rate of the next time slot, ρ' 2 Indicates the predicted PDCCH resource occupancy rate of the current time slot.

[0260] 6. If the target flag associated with the second type is PDCCH_sym_change_flag_2 = 1, update p 2 =ρ_current.

[0261] For example, for the first time slot of the second type scheduled (hereinafter referred to as the first time slot), PDCCH_sym of the first time slot is 1 (ie, the number of initial symbols configured is N).2 ). At the end of the first time slot scheduling, the actual PDCCH resource occupancy of the first time slot can be calculated.

[0262] For the second time slot of the second type scheduled (hereinafter referred to as the second time slot), since the value of the target flag bit (i.e., the PDCCH symbol number change flag bit) PDCCH_sym_change_flag_2 associated with the second type is the configured initial value 1, the predicted PDCCH resource occupancy rate of the second time slot is ρ 2 = ... 2 , determine the PDCCH_sym of the second time slot.

[0263] Furthermore, it can be determined whether the PDCCH_sym of the first time slot is the same as the PDCCH_sym of the second time slot. If they are the same, PDCCH_sym_change_flag_2 = 0. If they are different, PDCCH_sym_change_flag_2 = 1. After the time slot scheduling of the second time slot is completed, the actual PDCCH resource occupancy of the second time slot can be calculated.

[0264] For the third time slot of the second type scheduled (hereinafter referred to as the third time slot), determine whether the value of PDCCH_sym_change_flag_2 is 0. If PDCCH_sym_change_flag_2=0, set the value of ρ of the third time slot to 2 =(1-α)*ρ' 2 +α*ρ_current, where ρ' 2 represents the predicted PDCCH resource occupancy rate of the second time slot, and ρ_current represents the actual PDCCH resource occupancy rate of the second time slot. If PDCCH_sym_change_flag_2 = 1, then let ρ of the third time slot 2 =ρ_current. The subsequent step 6.2 can be adopted to calculate the value of ρ in the third time slot. 2 , determine the PDCCH_sym of the third time slot.

[0265] Furthermore, it can be determined whether the PDCCH_sym of the second time slot is the same as the PDCCH_sym of the third time slot. If they are the same, PDCCH_sym_change_flag_2 = 0. If they are different, PDCCH_sym_change_flag_2 = 1. After the time slot scheduling of the third time slot is completed, the actual PDCCH resource occupancy of the third time slot can be calculated.

[0266] The scheduling process of subsequent time slots is similar to that of the second time slot and the third time slot, and is not listed here one by one.

[0267] Further, we can refer to i (i=1,2) value, set N i The value of (i=1,2).

[0268] Step 6.2, determine the PDCCH_sym used in the next time slot (ie, the number of symbols required to be occupied by the PDCCH carried by the next time slot, referred to as the number of PDCCH symbols for short).

[0269] If i <ρ_thr_low, it indicates that the predicted PDCCH resource occupancy rate of the next time slot is low, and the number of PDCCH symbols in the next time slot should be reduced, that is, PDCCH_sym=N in the next time slot i =max(1,N i '-1); where N i 'Indicates PDCCH_sym of the current time slot.

[0270] If i >ρ_thr_high, it indicates that the predicted PDCCH resource occupancy rate of the next time slot is high, and the number of PDCCH symbols in the next time slot should be increased: PDCCH_sym=N i =min(N_max,N i '+1).

[0271] If ρ_thr_low ≤ ρ i ≤ρ_thr_high, then set PDCCH_sym=N i '.

[0272] If the PDCCH_sym of the next time slot is different from the PDCCH_sym of the current time slot, the corresponding flag bit PDCCH_sym_change_flag_i is set to 1, otherwise PDCCH_sym_change_flag_i is set to 0. Wherein, i=1,2.

[0273] In summary, the technical solution provided by this application has at least the following advantages compared with the prior art:

[0274] 1. The scheduling method is more flexible and the PDCCH resource occupancy rate is higher;

[0275] 2. When the number of symbols occupied by PDCCH changes, there is no need to send RRC reconfiguration message to the terminal device. It is completely determined by the access network device, and the number of symbols PDCCH_sym can take effect immediately;

[0276] 3. When counting PDCCH resources, the periodic form is not used. When the parameters are set reasonably, the changes in PDCCH resource occupancy rate can be reflected more quickly, so the solution is more flexible.

[0277] 4. Each terminal device has the ability to use all PDCCH symbols, and there is no need to group the terminal devices. Moreover, the single-symbol CORESET configuration enables the overall PDCCH resources to be allocated in a frequency domain-first manner, with no resource waste and higher resource utilization.

For example, the applicable system can be a global system of mobile communication (Global System of Mobile communication, referred to as GSM) system, code division multiple access (Code Division Multiple Access, referred to as CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, referred to as WCDMA) general packet radio service (General Packet Radio Service, referred to as GPRS) system, long term evolution (long term evolution, referred to as LTE) system, LTE frequency division duplex (Frequency Division Duplex, referred to as FDD) system, LTE time division duplex (time division duplex, referred to as TDD) system, advanced long term evolution (Long Term Evolution Advanced, referred to as LTE-A) system, Universal Mobile Telecommunication System (Universal Mobile Telecommunication System, referred to as UMTS), Worldwide interoperability for Microwave Access (Worldwide interoperability for Microwave Access, referred to as WiMAX) system, 5G new air interface (NewRadio, referred to as NR) system, etc. These various systems include terminals and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.
