Description

Method for communication based on UE capability, UE and network side equipment

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method for performing communication based on UE capability, a UE, and a network device.

Background

The 5G NR (New Radio) system is a global 5G standard designed based on a New air interface of OFDM (Orthogonal Frequency Division Multiplexing ), and is also a very important cellular mobile technology base for the next generation, and the 5G technology will realize ultra-low delay and high reliability.

In the NR R17 project, in order to support a special application scenario, such as an industrial sensor, a wearable device, a city monitoring device, etc., it is considered to introduce a low-complexity UE, which is applied to a communication scenario with special requirements, and the low-complexity UE has special requirements for transmission delay, power consumption, data transmission rate, etc., and therefore needs to have special characteristics, such as a lower number of transmit and receive antennas, a lower bandwidth, and a characteristic of half duplex FDD (Frequency Division duplex).

For application scenarios of low complexity UEs, the network device may use different scheduling strategies, and therefore needs to identify this type of UE and determine its UE capabilities. Although the current communication supports the reporting of the UE capability, the UE uniformly adopts the parameter set related to the UE to carry out the reporting of the UE capability, the currently defined parameter set related to the UE contains more parameters and does not contain the UE capability parameters applied to the low-complexity UE, so that the current network equipment cannot better identify the terminal with the low-complexity type and determine the UE capability of the terminal. In addition, the current reporting of the UE capability needs to wait for the UE to complete access and activate security before reporting, and the network side device cannot obtain the UE capability in the process of accessing the UE to the network, so that access control cannot be better performed for the UE and different scheduling schemes cannot be adopted. Therefore, after a low-complexity terminal is introduced, the current method for communication based on the UE capability of the user equipment cannot report the UE capability of the type of UE more effectively and enable the network device to identify the type of UE better.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the embodiment of the present application, "and/or" describes an association relationship of associated objects, which means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

For convenience of understanding, terms referred to in the embodiments of the present invention are explained below:

1) random access: the method is a process from the time when a terminal sends a random access preamble to a network to try to access the network to the time when a basic signaling connection is established between the terminal and the network; the random access process comprises the following steps: the UE sends a random access lead code to the network side equipment; after receiving the random access lead code, the network side equipment sends a random access response message to the UE; after receiving the random access response message, the UE sends a random access message 3(MSG3) to the network side device, where the message carries an RRC connection or a recovery request for contention resolution; after receiving the MSG3, the network side sends a contention resolution random access message 4(MSG4), which may carry an RRC connection setup or recovery message. In addition to the above 4-step random access scheme, a 2-step random access scheme is also currently supported. And will not be described in detail herein.

2) URLLC (Ultra Reliable Low Latency Communication) service: the 3GPP defines three major directions of a 5G application scenario as eMBB (mobile broadband enhancement), mtc (mass machine type communication), URLLC (ultra-high reliable ultra-low latency communication); the URLLC and the mMTC are application scenes of the Internet of things, but the respective emphasis points are different, the URLLC mainly reflects the communication requirement between equipment, the mMTC mainly develops in a frequency band below 6GHz, and is applied to a large-scale Internet of things at the same time, so that the information interaction between a user and the equipment is mainly reflected; URLLC service has two basic features, namely high reliability and low delay.

Example 1

The embodiment of the invention is applied to a scene that the UE of a preset type under the 5G NR communicates with the network side equipment, and the R17 project of the 5G NR introduces the UE with low complexity for supporting special application scenes such as industrial sensors, wearable equipment, city monitoring equipment and the like. The requirements of low complexity UEs on latency, power consumption, data rate, etc. are different from those of conventional user terminals UEs. Compared with a conventional user terminal UE, a low-complexity UE is expected to support the following characteristics:

reducing the number of receive antennas RX/transmit antennas TX of the UE; smaller UE bandwidth; support for half duplex FDD mode; relaxed UE processing time; relaxed UE processing capabilities; the physical downlink control channel PDCCH monitoring can be reduced by reducing the number of blind decoding and Control Channel Elements (CCE); supporting extended DRX in idle state and/or Inactive Inactive state; relaxed RRM of fixed devices.

The UE capability is a parameter set related to the UE, and the network side device can make correct scheduling and configuration for the UE after determining the UE capability. Currently, the UE capability is reported in the UE attachment process, and there are two main ways: and reporting the request and actively reporting the request based on the network side. The request report based on the network side mainly relates to two processes: the method comprises the steps that UE capacity request and UE capacity report are carried out, and when the network equipment needs the UE to report the UE capacity, a UE capacity request instruction is sent to the UE; and after receiving the UE capability request instruction, the UE reports the UE capability according to the instruction.

The currently defined parameter set related to the UE does not distinguish capability classification levels, does not include UE capability parameters applied to the low-complexity UE, and introduces the capability supported by the corresponding complexity UE based on the current UE capability reporting scheme, and then for the low-complexity UE, the current UE capability reporting scheme has a high overhead, so that the existing UE capability reporting method cannot report the UE capability of the low-complexity UE more effectively, and therefore, the existing network device cannot better identify a terminal of a low-complexity type and determine the UE capability thereof.

In view of this, an embodiment of the present invention provides a system for performing communication based on UE capability, which is applied to a scenario where a low-complexity user terminal accesses a network and/or reports the UE capability, and a network side device controls UE access and/or confirms the UE capability, as shown in fig. 1, which is a schematic diagram of the system for performing communication based on UE capability provided in the embodiment of the present invention. As shown in the figure, the system for communicating based on UE capability according to the embodiment of the present invention includes a user terminal 101 and a network side device 102.

In the embodiments of the present invention, a user equipment UE may specifically refer to an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a Mobile station in a 5G Network, or a subscribing device in a future evolved Public Land Mobile Network (PLMN) Network, etc.

The network side device may be a next generation Base Station (gNB) in a 5G System, and may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) System, or the like.

For convenience of description, only 1 low-complexity terminal is illustrated in fig. 1, and in an actual system, multiple low-complexity terminals may coexist, which is not described herein again. It should be noted that the above system architecture is only an example of the system architecture applicable to the embodiment of the present invention, and the system architecture applicable to the embodiment of the present invention may also add other entities or reduce part of the entities compared to the system architecture shown in fig. 1.

In the system, the UE 101 is configured to determine a UE capability classification level to which the UE belongs; accessing the network according to the determined UE capability classification level, or reporting the determined UE capability classification level to network side equipment, or accessing the network according to the determined UE capability classification level and reporting the determined UE capability classification level to the network side equipment;

the network side device 102 is configured to control access of a preset type of UE, where the preset type of UE can determine a UE capability classification level to which the preset type of UE belongs; or receiving the UE capability classification grade reported by the UE, and accessing and/or scheduling the UE based on the UE capability classification grade; or controlling the access of the UE of a preset type, wherein the UE of the preset type can determine the capability classification level of the UE, receive the capability classification level of the UE reported by the UE, and perform access or scheduling or access and scheduling on the UE based on the capability classification level of the UE.

The UE 101 is a preset type terminal, in this embodiment, a preset type UE, where the preset type UE can determine a UE capability classification level to which the UE belongs, specifically, different UE capability classification levels are predefined in advance, and the classification level may be defined based on a protocol, for example, a protocol defined by 38.306 in an NR system. Different UE capability level classifications may be defined according to preset information, and optionally, this embodiment may, but is not limited to, classify the UE capability level by using at least one of the following information: the UE service classification level may be a preset UE service communication requirement, a preset UE hardware capability parameter, and a preset application scenario, that is, preset information may be obtained through the UE capability classification level, for example, the communication requirement, the application scenario, or the hardware capability of the UE capability classification level terminal is obtained.

When communication is carried out based on the UE capacity, the UE determines the UE capacity classification level of the UE according to different defined UE capacity classification levels and corresponding capacity parameters.

As an optional implementation manner, in the defined UE capability classification levels, each UE capability classification level corresponds to one UE capability, one UE capability corresponds to at least one capability parameter, and the value of each capability parameter is a preset value, where the capability parameter may be the number of supported transmit/receive antennas, the supported bandwidth, and/or the like, and/or the supported application scenario, the service communication requirement, and the like;

as another optional implementation manner, in the defined UE capability classification levels, each UE capability classification level corresponds to a UE capability range, one UE capability range corresponds to at least one capability parameter, and the value range of each capability parameter is a preset value range, where the capability parameter may be the number of supported transceiving antennas, the supported bandwidth, and/or the like, and/or the supported application scenario, the service communication requirement, and the like.

After the UE determines the UE capability classification level to which the UE belongs, the UE accesses the network according to the determined UE capability classification level, and a possible way is that the network side broadcasts indication information, where the indication information may indicate the UE capability classification level information of the supported access or whether the UE supports the access of a preset type terminal, and the network side may also broadcast access control parameters configured for the preset type terminal or each UE capability classification level, so that the UE determines whether the network side supports the self-access and performs access control to determine whether the network can be accessed, and the UE selects the network access network supporting the self-access.

The UE reports the determined UE capability classification level to the network side, which may be an implicit reporting mode, such as implicit reporting by selecting a corresponding random access resource related to the UE capability level to trigger a random access procedure, thereby reporting through the used random access resource, or implicit reporting by selecting a corresponding random access resource related to the preset type terminal to trigger a random access procedure, thereby reporting through the used random access resource, or explicit reporting, such as reporting through a separate signaling.

The two steps can be implemented independently or in combination, for example, when the access to the network is implemented independently according to the determined UE capability classification level, the UE can select the corresponding network and/or the corresponding random access resource for access according to the UE capability classification information supported by the network side; when the determined UE capability classification level is reported to the network side device independently, the UE may report in a display manner. When the two are combined, the UE can select a corresponding network and/or a corresponding random access resource for access according to UE capability level classification information supported by the network side, and can report its UE capability level classification in an implicit manner or in a display manner during the random access. The two implementation modes can also be implemented together, the UE can select a corresponding network and/or a corresponding random access resource for access according to UE capability classification level information supported by the network side device, can report part of UE capability information, such as a preset type terminal or a UE capability classification level, in a random access process in an implicit manner, and further report a specific UE capability parameter value or a UE capability classification level in a display manner.

Optionally, in this embodiment, a network is accessed according to a UE capability classification level determined by the UE, and the network side device controls access of a preset type of UE, and/or the UE reports the determined UE capability classification level to the network side device, and before the network side device accesses and/or schedules the UE based on the UE capability classification level, the network side device performs at least one of the following:

1) the network side equipment broadcasts indication information through system information so that the UE can determine whether the network side equipment supports the terminal access of the UE capability classification level to which the UE belongs, the UE receives the indication information, and the network side equipment determines whether the network side equipment supports the terminal access of the UE capability classification level to which the UE belongs according to the indication information.

As an optional implementation manner, the indication information is used to indicate whether the network side device supports a preset type of terminal access, and may specifically be represented by a preset value of one bit. Specifically, the network side device broadcasts 1-bit indication information through the system information, and indicates whether to support the preset type of terminal access or not through the value of the indication information. And after receiving the indication information, the UE determines whether the network side equipment supports the UE access according to the value of the indication information, and when determining that the network side equipment supports the access, the UE selects to access the network where the network side equipment is located.

For example, the value of the one-bit indication information is 1, which corresponds to that the network side device supports the terminal access of the preset type, and the value of the indication information is 0, which corresponds to that the network side device does not support the terminal access of the preset type. Then, after the network side device broadcasts the indication information, the corresponding UE may determine whether to access the network where the network side device is located according to the value of the indication information. The preset type of terminal may be a terminal of a specific type, such as a low complexity terminal, or a terminal of a specific application scenario, such as an industrial sensor, or a terminal of all UE capability classification levels, or a terminal of a part or specific UE capability classification levels, or a terminal satisfying a certain service communication requirement, or a terminal satisfying a certain UE hardware capability parameter, or a terminal capable of determining a UE capability classification level to which the terminal belongs.

As another optional implementation manner, the indication information is used to indicate whether the network side device supports terminal access of each UE capability classification level, and may specifically be implemented in a Bitmap manner, where each bit of the indication information corresponds to one UE capability classification level, and a preset value of each bit is used to indicate whether terminal access corresponding to the UE capability classification level corresponding to the bit is supported. Specifically, the network side device broadcasts a Bitmap through system information, and indicates a terminal corresponding to the UE capability classification level supporting access through a value of the Bitmap. And after receiving the indication information, the UE determines whether the network side equipment supports the terminal access corresponding to the UE capability classification level to which the UE belongs according to the value of the indication information, and when determining that the network side equipment supports the access, the UE selects to access the network where the network side equipment is located.

For example, suppose that 8 UE capability classification levels are included, which are UE capability classification levels 1 to 8, respectively, the 8 UE capability classification levels are respectively corresponding to 1 st to 8 th bits in the indication information, a bit value of 1 corresponds to a terminal access of the network side device that supports the UE capability classification level to which the UE belongs, and a bit value of 0 corresponds to a terminal access of the network side device that does not support the UE capability classification level to which the UE belongs. When the network side device only supports the terminal access corresponding to the UE capability class 2 and the UE capability class 3, the indication information is 01100000. After receiving the indication information, the UE may determine, according to the value of each bit of the indication information, that the UE capability classification levels supported by the network side device for access are UE capability classification levels 2 and 3, respectively, and if the UE capability classification level corresponding to the UE is included, determine that the network side device allows the terminal to access, otherwise determine that the network side device does not allow the terminal to access.

2) And the network side equipment broadcasts the access control parameters configured for the preset type of terminal through the system information, and the UE receives the access control parameters and then performs access judgment. And if the network allows access, the UE triggers a random access process to access the network, otherwise, the UE does not access the network.

Specifically, the network side device configures different access control parameters for different preset types of terminals, and notifies the UE through broadcasting, thereby implementing different access control schemes for the preset types of UEs. The preset type of terminal may be a terminal of a specific type, such as a low complexity terminal, or a terminal of a specific scenario, such as an industrial sensor, or a terminal of all UE capability classification levels, or a terminal of a part or specific UE capability classification level.

3) And the network side equipment broadcasts access control parameters configured for the terminals with different UE capability classification levels through system information, and after receiving the access control parameters, the UE selects corresponding access control parameters according to the UE capability classification level of the UE and performs access judgment. And if the network allows access, the UE triggers a random access process to access the network, otherwise, the UE does not access the network.

Specifically, the network side device configures different access control parameters for the terminals of each UE capability classification level, and notifies the UE through broadcasting, thereby implementing different access control schemes for the terminals of different UE capability classification levels. For example, a more relaxed access control parameter is set for the terminal of UE capability class 1, and a more strict access control parameter is set for the terminal of UE capability class 2, so that the terminal of UE capability class 2 is controlled to access the network more strictly.

4) The method comprises the steps that network side equipment broadcasts random access resources and/or random access configuration distributed for a preset type of terminal through system information, UE receives the random access resources and/or the random access configuration, and the preset type of terminal can determine the capability classification level of the UE.

Specifically, the network side device allocates different random access resources and/or random access configurations to terminals of different preset types, and notifies the UE through broadcasting. Therefore, when the UE receives the random access resource and/or the random access configuration which is broadcasted by the network side equipment through the system information and is allocated to the terminal of the preset type, if the preset type of the broadcast is determined to contain the type of the UE, the network is determined to support the terminal of the type to which the UE belongs to access, and the random access resource and/or the random access configuration corresponding to the type of the network is selected to access the network where the network side equipment is located.

5) The network side equipment broadcasts the random access resources and/or the random access configuration distributed to the terminals with different UE capability classification levels through the system information, and the UE receives the random access resources and/or the random access configuration.

Specifically, the network side device allocates different random access resources and/or random access configurations to terminals of different UE capability classification levels, and notifies the UE through broadcasting. Therefore, when the UE receives the random access resource and/or the random access configuration which is broadcasted by the network side equipment through the system information and is allocated to the terminals with different UE capability classification levels, if the broadcasted random access resource and/or the random access configuration comprises the random access resource and/or the random access configuration of the UE capability classification level of the UE, the UE determines that the network supports the access of the terminal with the UE capability classification level to which the UE belongs, and selects the corresponding random access resource and/or the random access configuration according to the UE capability classification level to which the UE belongs to access the network where the network side equipment is located.

After determining the UE capability classification level, the UE may report the determined UE capability classification level to the network side device actively, or report the UE capability classification level after receiving capability request information sent by the network side device. The reporting opportunity may be during the access process or after the UE accesses the network where the network side device is located.

As described above, after the UE determines the UE capability classification level, the two steps may be implemented separately or in combination, and the embodiment of the present invention may be, but is not limited to, implemented by performing at least one of the following steps:

1) when the UE determines that the network side equipment allows the UE to access, access control judgment is carried out according to the UE capability classification level, and if the access is allowed, the access process is triggered;

when the UE determines that the network side device allows the UE to access, the UE performs access control judgment according to the UE capability classification level, and in the specific embodiment, reference is made to the description of determining whether to select an access network by the UE, which is not repeated here.

2) In the random access process, the UE selects a random access resource corresponding to the determined UE capability classification level and triggers the random access process;

and the network side equipment distributes different random access resources for different UE capacity classification levels and transmits the random access resources to the UE through system broadcasting, and the UE selects the random access resources corresponding to the determined UE capacity classification levels in the random access process and triggers the random access process.

And the network side equipment allocates different random access resources for different UE capability classification levels according to the different UE capability classification levels and broadcasts the resources through system information. The UE receives the random access resource broadcasted by the network side equipment, selects the corresponding random access resource for random access according to the determined UE capability classification level of the UE, and the network side equipment determines the UE capability classification level corresponding to the UE according to the random access resource selected when the UE performs random access. Therefore, the UE can implicitly report the UE capability classification level thereof through the random access process by selecting the random access resource consistent with the UE capability classification level through the random access resource distributed for different UE capability classification levels by the network side and triggering the random access process without reporting the specific UE capability classification level to the network side equipment, and the network side equipment can also implicitly determine the UE capability classification level reported by the UE through the random access process.

3) And in the random access process, the UE triggers the random access process by selecting the random access configuration corresponding to the determined UE capability classification level.

And the network side equipment makes different random access configurations for different UE capacity classification levels according to the different UE capacity classification levels and broadcasts the configurations through system messages. The UE receives the random access configuration broadcasted by the network side equipment, selects the corresponding random access configuration for random access according to the determined UE capability classification level to which the UE belongs, the network side equipment configures different random access controls for different UE capability classification levels, and can control the access of the terminals according to different requirements of the terminals with different UE capability classification levels, for example, the terminals with smaller delay requirements are configured with longer random access related timers, so as to improve the access success probability.

The network side equipment controls the access of the UE of the preset type, receives the UE capability classification level reported by the UE, can be implemented independently or in combination, and can be implemented independently or in combination. When the network side device receives the UE capability classification level reported by the UE, it may perform access/scheduling based on the UE capability classification of the UE.

One possible situation is that a random access resource allocated to a preset type of terminal is broadcasted through system information, or a random access resource allocated to terminals with different UE capability classification levels is broadcasted through system information, and a network side device determines the capability classification level of the UE according to a UE capability classification level corresponding to the random access resource through the random access resource used by the terminal in a random access process.

The network side device receives the UE capability classification level reported by the UE, which may be implicitly receiving the UE capability classification level reported by the UE through the random access resource in the random access process or explicitly receiving the UE capability classification level, specifically, when the UE accesses the network where the network side device is located, the UE reports the determined UE capability classification level to the network side device by establishing a message sent in the RRC connection process, and the network side device receives the UE capability classification level reported by the UE or reports the UE capability classification level to the network side device through the UE capability reporting process after the UE accesses the network where the network side device is located.

In this embodiment, the random access resource includes a time-frequency resource and/or a random access Preamble and/or a PUSCH resource, and the random access configuration includes a random access repetition number and/or a random access related timer.

After the UE determines the network where the access network side equipment is located, the determined UE capability classification level is reported to the network side equipment through at least one of the following items:

an RRC connection setup request message;

an RRC connection resume request message;

an RRC reestablishment request message;

MAC layer signaling;

physical layer signaling;

RRC signaling;

an RRC connection setup complete message;

an RRC connection recovery complete message;

RRC reestablishment complete message.

In the embodiment of the invention, the UE capability classification level corresponds to at least one of the following information:

presetting UE service communication requirements;

presetting UE hardware capability parameters;

and (4) presetting an application scene.

The UE service communication requirement parameters include, for example, time delay, rate, and/or power consumption requirements, the UE hardware capability parameters include, for example, the number of antennas, bandwidth capability, and the like, and the application scenario parameters include, for example, an ultra-high-reliability low-time-delay URRLC service, a mass machine type terminal communication mtc service, and the like. Different UE capability levels correspond to different UE service communication requirements and/or UE hardware capabilities and/or application scenarios.

In the embodiment of the invention, the UE which determines the UE capability classification level to which the UE belongs is a terminal of a preset type. The preset type of terminal is at least one of the following:

a low complexity terminal;

the terminal is applied to a preset application scene;

the terminal meets the preset UE service communication requirement;

the terminal meets preset UE hardware capability parameters;

presetting a terminal of UE capability classification grade;

and the terminal of the UE capability classification level can be determined.

In this embodiment, when reporting the UE capability, the UE may report only the UE capability classification level to which the UE belongs, or report only the specific UE capability parameter of the UE, or report the UE capability classification level to which the UE belongs and the specific UE capability parameter. In the predefined different UE capability classification levels and corresponding capability parameters applied to the low-complexity UE, if each UE capability classification level corresponds to a UE capability range, the UE reports the specific UE capability parameters to the network side device, or reports the specific UE capability parameters when the determined UE capability classification level is reported to the network side device. The UE may report the UE capability classification level in the implicit or explicit manner, and report the specific capability parameter through the same message or an additional message.

The following provides possible implementation manners of classifying the classes based on the UE capabilities by the network side device and the UE in conjunction with the flowchart.

The system architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the system architecture and the appearance of a new service scenario.

Example 2

In the embodiment of the present invention, before reporting and determining the UE capability, the UE and the network side device preset the capability classification levels applied to different UEs and their corresponding capability parameters, specifically adopting any one of the following manners:

in the first mode, each UE capability classification level in different UE capability classification levels corresponds to one UE capability, one UE capability corresponds to at least one capability parameter, and the value of each capability parameter is a preset value.

In specific implementation, the corresponding relationship between the UE capability classification level and the capability parameter corresponding to the UE capability may be defined according to at least one of the UE service communication requirement parameter, the UE hardware capability parameter, and the application scenario parameter. Three examples are given below:

1) and dividing the UE capacity classification grades according to the time delay of the UE communication service requirement, and respectively corresponding different UE capacity classification grades to different UE capacities, so that each UE capacity classification grade corresponds to a preset time delay parameter or range in preset UE communication service requirement parameters. The value corresponding to each UE capability parameter is defined based on the preset time delay parameter.

For example, two UE capability classification levels are defined, wherein the delay requirement value corresponding to the UE capability classification level 1 is set to be 5ms, and the delay requirement value corresponding to the UE capability classification level 2 is set to be 10 ms. Namely, the delay parameter 5ms corresponding to the UE capability classification level 1 applied to the preset type UE, and the delay parameter 10ms corresponding to the UE capability classification level 2 applied to the preset type UE.

2) And respectively corresponding different UE capacity classification levels to different UE capacities according to the application scene parameters, so that each UE capacity classification level corresponds to a preset application scene. The value corresponding to each UE capability parameter is defined based on the preset application scene.

For example, two UE capability classification levels are defined, where an application scenario corresponding to the UE capability classification level 1 is set as a URRLC service, and an application scenario corresponding to the UE capability classification level 2 is set as an mtc service. That is, the UE capability classification level 1 applied to the preset type UE corresponds to the URRLC service, and the UE capability classification level 2 applied to the preset type UE corresponds to the mtc service.

3) And according to the antenna parameter and the bandwidth parameter in the UE hardware capability parameter, respectively corresponding different UE capability classification levels to different UE capabilities, wherein each UE capability classification level corresponds to the antenna parameter and the bandwidth parameter in the preset hardware capability parameter, and the value corresponding to each UE capability parameter is defined based on the preset antenna parameter and the preset bandwidth parameter.

For example, two UE capability classification levels are defined, where the UE capability classification level 1 corresponds to the number of transmit/receive antennas 1 × 1 and the bandwidth value 5M, and the UE capability classification level 2 corresponds to the number of transmit/receive antennas 2 × 2 and the bandwidth value 10M. That is, the capability parameters corresponding to the UE capability class 1 applied to the preset type UE are the number of transmit/receive antennas 1 × 1 and the bandwidth value 5M, and the capability parameters corresponding to the UE capability class 2 applied to the preset type UE are the number of transmit/receive antennas 2 × 2 and the bandwidth value 10M.

And in the second mode, each UE capability classification grade in different UE capability classification grades corresponds to one UE capability range, one UE capability range corresponds to at least one capability parameter, and the value range of each capability parameter is a preset numerical value range.

In specific implementation, the corresponding relationship between the UE capability classification level and the capability parameter corresponding to the UE capability range may be defined according to at least one of the UE service communication requirement parameter, the UE hardware capability parameter, and the application scenario parameter.

For example, different UE capability classification levels may be respectively corresponding to different UE capability ranges according to a bandwidth parameter in the UE hardware capability parameters, where the capability parameter corresponding to each UE capability range is a bandwidth parameter in the preset UE hardware capability parameters, and the value range of the capability parameter corresponding to each UE capability range is a preset bandwidth value range. For example, two UE capability classification levels are defined, wherein a bandwidth value range corresponding to the UE capability classification level 1 is set to be 5M-30M, and a bandwidth value range corresponding to the UE capability classification level 2 is set to be 30M-60M. That is, the capability parameter applied to the UE capability class level 1 is a bandwidth parameter range of 5M to 30M, and the capability parameter applied to the UE capability class level 2 is a bandwidth parameter range of 30M to 60M.

In the embodiment of the present invention, when the UE is a low-complexity UE, each UE capability classification level in different UE capability classification levels corresponds to a UE complexity, where one UE complexity corresponds to one UE capability, one UE capability corresponds to at least one capability parameter, and values of the capability parameters are preset values, or one UE complexity corresponds to one UE capability range, one UE capability range corresponds to at least one capability parameter, and values of the capability parameters are preset value ranges.

Different UE capability parameters of different UEs are different, and the corresponding complexity is different, so that different UE complexity can be defined according to the UE capability parameters, different UE capability classification levels correspond to different UE complexity, and the capability parameter corresponding to the UE capability classification level is the capability parameter corresponding to the UE complexity.

In specific implementation, the corresponding relationship between the UE capability classification level and the capability parameter corresponding to the UE complexity may be defined according to at least one of the UE service communication requirement parameter, the UE hardware capability parameter, and the application scenario parameter.

The UE capability classification level may be only applied to a preset type of terminal, for example, only applied to a low complexity terminal, or only applied to a terminal that presets UE service communication requirements, UE hardware capability parameters, and application scenarios.
